  • 5       WARNINGS AND PRECAUTIONS

    5.1       New Primary Malignancies

    Cutaneous Malignancies

    In the BREAK-3 study in patients with unresectable or metastatic melanoma, cutaneous squamous cell carcinomas and keratoacanthomas (cuSCC) occurred in 7% of patients receiving TAFINLAR.

    Across clinical trials of TAFINLAR monotherapy, the incidence of cuSCC was 11%. Of those patients who developed new cuSCC, approximately 33% developed one or more cuSCC with continued administration of TAFINLAR.

    In the COMBI-d study in patients with unresectable or metastatic melanoma, the incidence of basal-cell carcinoma (BCC) in patients receiving TAFINLAR in combination with trametinib was 3.3% compared with 6% of patients receiving single-agent TAFINLAR. Among the 7 patients receiving TAFINLAR with trametinib who developed BCC, 2 experienced more than one occurrence (range: 1 to 3). Cutaneous squamous cell carcinomas and keratoacanthomas and new primary melanoma occurred in 3% and 0.5% of patients receiving TAFINLAR with trametinib, respectively.

    In the COMBI-AD study in the adjuvant treatment of melanoma, cuSCC and new primary melanoma occurred in 1% and < 1% of patients receiving TAFINLAR plus trametinib, respectively.

    In Study BRF113928 in patients with NSCLC, cuSCC occurred in 3.2% of patients receiving TAFINLAR plus trametinib.

    Perform dermatologic evaluations prior to initiation of TAFINLAR, every 2 months while on therapy, and for up to 6 months following discontinuation of TAFINLAR.

    Non-cutaneous Malignancies

    Based on its mechanism of action, TAFINLAR may promote the growth and development of malignancies with activation of RAS through mutation or other mechanisms [see Warnings and Precautions (5.2)]. In the COMBI-d, COMBI-AD, and BRF113928 studies, non-cutaneous malignancies occurred in 1.4%, 1%, and 1.1% of patients receiving TAFINLAR with trametinib, respectively.

    Monitor patients receiving TAFINLAR for signs or symptoms of non-cutaneous malignancies. Permanently discontinue TAFINLAR for RAS mutation-positive non-cutaneous malignancies [see Dosage and Administration (2.7)].

    5.2       Tumor Promotion in BRAF Wild-Type Tumors

    In vitro experiments have demonstrated paradoxical activation of MAP-kinase signaling and increased cell proliferation in BRAF wild-type cells which are exposed to BRAF inhibitors. Confirm evidence of BRAF V600E or V600K mutation status prior to initiation of TAFINLAR as a single agent or in combination with trametinib [see Indications and Usage (1.6), Dosage and Administration (2.1)].

    5.3       Hemorrhage

    Hemorrhage, including major hemorrhage defined as symptomatic bleeding in a critical area or organ, can occur when TAFINLAR is administered with trametinib.

    In the COMBI-d study, the incidence of hemorrhagic events in patients receiving TAFINLAR with trametinib was 19% compared with 15% of patients receiving single agent TAFINLAR. Gastrointestinal hemorrhage occurred in 6% of patients receiving TAFINLAR with trametinib compared with 3% of patients receiving single agent TAFINLAR. Intracranial hemorrhage was fatal in 1.4% of patients receiving TAFINLAR with trametinib. No fatal hemorrhagic events were observed in the COMBI-AD study. In Study BRF113928, fatal hemorrhagic events occurred in 2.2% of patients receiving TAFINLAR with trametinib; these events were retroperitoneal hemorrhage and subarachnoid hemorrhage.

    Permanently discontinue TAFINLAR for all Grade 4 hemorrhagic events and for any Grade 3 hemorrhagic events that do not improve. Withhold TAFINLAR for Grade 3 hemorrhagic events; if improved, resume at the next lower dose level.

    5.4       Cardiomyopathy

    In the COMBI-d study, cardiomyopathy [defined as a decrease in LVEF ≥ 10% from baseline and below the institutional lower limit of normal (LLN)] occurred in 6% of patients receiving TAFINLAR with trametinib and 2.9% of patients receiving single agent TAFINLAR. Development of cardiomyopathy in patients receiving TAFINLAR and trametinib resulted in dose interruption or discontinuation of TAFINLAR in 4.4% and 1.0% of patients, respectively. In patients receiving single-agent TAFINLAR, development of cardiomyopathy resulted in dose interruption, reduction, or discontinuation in 2.4%, 0.5%, and 1.0% of patients, respectively. Cardiomyopathy resolved in 10 of 12 patients receiving TAFINLAR with trametinib and in 3 of 6 patients receiving single agent TAFINLAR.

    In the COMBI-AD study, cardiomyopathy (defined as a decrease in LVEF below the institutional LLN with an absolute decrease in LVEF > 10% below screening) occurred in 3% of patients receiving TAFINLAR with trametinib and resulted in discontinuation, dose reduction, and dose interruption of drug in 0.2%, 1.6%, and 2.1% of patients, respectively. Cardiomyopathy resolved in 12 of 14 patients receiving TAFINLAR with trametinib.

    In Study BRF113928, cardiomyopathy (defined as a decrease in LVEF below the institutional LLN with an absolute decrease in LVEF > 10% below baseline) occurred in 9% of patients receiving TAFINLAR with trametinib and resulted in dose interruption and permanent discontinuation of TAFINLAR in 3.2% and 2.2% of patients, respectively. Cardiomyopathy resolved in 4 of 8 patients receiving TAFINLAR and trametinib.

    Assess LVEF by echocardiogram or multigated acquisition (MUGA) scan before initiation of TAFINLAR with trametinib, one month after initiation of TAFINLAR, and then at 2- to 3-month intervals while on treatment. Withhold TAFINLAR for symptomatic cardiomyopathy or asymptomatic LV dysfunction of > 20% from baseline that is below institutional LLN. Resume TAFINLAR at the same dose level upon recovery of cardiac function to at least the institutional LLN for LVEF and absolute decrease ≤ 10% compared to baseline [see Dosage and Administration (2.7)].

    5.5       Uveitis

    Uveitis occurred in 1% of patients receiving TAFINLAR across multiple clinical trials and in 2% of patients receiving TAFINLAR with trametinib across randomized unresectable or metastatic melanoma trials. Treatment employed in clinical trials included steroid and mydriatic ophthalmic drops.

    Monitor patients for visual signs and symptoms of uveitis (e.g., change in vision, photophobia, eye pain). If iritis is diagnosed, administer ocular therapy and continue TAFINLAR without dose modification. If severe uveitis (i.e., iridocyclitis) or if mild or moderate uveitis does not respond to ocular therapy, withhold TAFINLAR and treat as clinically indicated. Resume TAFINLAR at the same or lower dose if improves to Grade 0 or 1. Permanently discontinue TAFINLAR for persistent Grade 2 or greater uveitis of > 6 weeks [see Dosage and Administration (2.7)].

    5.6       Serious Febrile Reactions

    Serious febrile reactions and fever of any severity complicated by hypotension, rigors or chills, dehydration, or renal failure, can occur with TAFINLAR.

    The incidence and severity of pyrexia are increased when TAFINLAR is administered with trametinib compared with TAFINLAR as a single agent [see Adverse Reactions (6.1)].

    In the BREAK-3 study, the incidence of fever (serious and non-serious) was 28% in patients receiving TAFINLAR and 10% in patients receiving dacarbazine. Serious febrile reactions and fever of any severity complicated by hypotension, rigors or chills occurred in 3.7% of patients receiving TAFINLAR.

    In the COMBI-d and COMBI-v studies, fever occurred in 54% of patients receiving TAFINLAR with trametinib. Approximately one-half of the patients who received TAFINLAR with trametinib and experienced pyrexia had 3 or more discrete episodes.

    Serious febrile reactions or fever of any severity complicated by severe rigors or chills, hypotension, dehydration, renal failure, or syncope, occurred in 17% of patients with unresectable or metastatic melanoma receiving TAFINLAR with trametinib. Fever was complicated by severe chills/rigors in 0.4%, dehydration in 1.8%, renal failure in 0.5%, and syncope in 0.7% of patients.

    Withhold TAFINLAR for fever of greater than or equal to 101.3ºF, or fever complicated by hypotension, rigors or chills, dehydration, or renal failure, and evaluate for signs and symptoms of infection. Monitor serum creatinine and other evidence of renal function during and following severe pyrexia. Refer to Table 2 for recommended dose modifications for adverse reactions [see Dosage and Administration (2.7)]. Administer antipyretics as secondary prophylaxis when resuming TAFINLAR if patient had a prior episode of severe febrile reaction or fever associated with complications. Administer corticosteroids (e.g., prednisone 10 mg daily) for at least 5 days for second or subsequent pyrexia if temperature does not return to baseline within 3 days of onset of pyrexia, or for pyrexia associated with complications such as dehydration, hypotension, renal failure or severe chills/rigors, and there is no evidence of active infection.

    5.7       Serious Skin Toxicity

    Across clinical trials of TAFINLAR administered with trametinib in patients with unresectable or metastatic melanoma, serious skin toxicity occurred in 0.7% of patients.

    Withhold TAFINLAR for intolerable or severe skin toxicity. Resume TAFINLAR at a lower dose in patients with improvement or recovery from skin toxicity within 3 weeks. Permanently discontinue TAFINLAR if skin toxicity has not improved within 3 weeks [see Dosage and Administration (2.7)].

    5.8       Hyperglycemia

    In the BREAK-3 study, 5 of 12 patients with a history of diabetes required more intensive hypoglycemic therapy receiving TAFINLAR. The incidence of Grade 3 hyperglycemia based on laboratory values was 6% in patients receiving TAFINLAR.

    In the COMBI-d study, 27% of patients with a history of diabetes receiving TAFINLAR with trametinib and 13% of patients with a history of diabetes receiving single agent TAFINLAR required more intensive hypoglycemic therapy. Grade 3 and Grade 4 hyperglycemia based on laboratory values occurred in 5% and 0.5% of patients, respectively, receiving TAFINLAR with trametinib. For patients receiving single agent TAFINLAR, 4.3% of patients had Grade 3 hyperglycemia based on laboratory values and no patients had Grade 4 hyperglycemia.

    Monitor serum glucose levels upon initiation and as clinically appropriate when TAFINLAR is administered in patients with preexisting diabetes or hyperglycemia. Initiate or optimize anti-hyperglycemic medications as clinically indicated.

    5.9       Glucose-6-Phosphate Dehydrogenase Deficiency

    TAFINLAR, which contains a sulfonamide moiety, confers a potential risk of hemolytic anemia in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency. Monitor patients with G6PD deficiency for signs of hemolytic anemia while taking TAFINLAR.

    5.10       Risks Associated with Combination Treatment

    TAFINLAR is indicated for use in combination with trametinib. Review the Prescribing Information for trametinib for information on the serious risks of trametinib prior to initiation of TAFINLAR with trametinib.

    5.11       Embryo-Fetal Toxicity

    Based on findings from animal studies and its mechanism of action, TAFINLAR can cause fetal harm when administered to a pregnant woman. Dabrafenib was teratogenic and embryotoxic in rats at doses three times greater than the human exposure at the recommended clinical dose. Advise pregnant women of the potential risk to a fetus. Advise female patients of reproductive potential to use effective non-hormonal contraception, since TAFINLAR can render hormonal contraceptives ineffective, during treatment with TAFINLAR and for 2 weeks after the last dose [see Drug Interactions (7.2), Use in Specific Populations (8.1, 8.3)].

    There are additional adverse reactions associated with trametinib. Refer to the trametinib prescribing information for additional information.

    6.1       Clinical Trials Experience 

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

    The data described in the Warnings and Precautions section reflect exposure to TAFINLAR administered as a single agent in 586 patients with various solid tumors and exposure to TAFINLAR administered with trametinib in 559 patients with unresectable or metastatic melanoma and 93 patients with NSCLC. The safety of TAFINLAR as a single agent was evaluated in 586 patients with BRAF V600 mutation-positive unresectable or metastatic melanoma, previously treated or untreated, who received TAFINLAR 150 mg orally twice daily until disease progression or unacceptable toxicity, including 181 patients treated for at least 6 months and 86 additional patients treated for more than 12 months. TAFINLAR was studied in open-label, single-arm trials and in an open-label, randomized, active-controlled trial. The median daily dose of TAFINLAR was 300 mg (range: 118 to 300 mg).

    Metastatic or Unresectable BRAF V600E or V600K Mutation-Positive Melanoma

    TAFINLAR as a Single Agent

    The safety of TAFINLAR was evaluated in BREAK-3, a multicenter, international, open-label, randomized (3:1), controlled trial allocated 250 patients with unresectable or metastatic BRAF V600E mutation-positive melanoma to receive TAFINLAR 150 mg orally twice daily (n = 187) or dacarbazine 1000 mg/m2 intravenously every 3 weeks (n = 63) [see Clinical Studies (14.1)]. The trial excluded patients with abnormal left ventricular ejection fraction (LVEF) or cardiac valve morphology (≥ Grade 2), corrected QT interval ≥ 480 milliseconds on electrocardiogram, or a known history of glucose-6-phosphate dehydrogenase deficiency. The median duration on treatment was 4.9 months for patients treated with TAFINLAR and 2.8 months for dacarbazine-treated patients. The population exposed to TAFINLAR was 60% male, 99% white, and had a median age of 53 years.

    The most common adverse reactions (≥ 20%) in patients treated with TAFINLAR were, in order of decreasing frequency: hyperkeratosis, headache, pyrexia, arthralgia, papilloma, alopecia, and palmar-plantar erythrodysesthesia syndrome (PPES).

    The incidence of adverse events resulting in permanent discontinuation of study medication in the BREAK-3 study was 3% for patients treated with TAFINLAR and 3% for patients treated with dacarbazine. The most frequent (≥ 2%) adverse reactions leading to dose reduction of TAFINLAR were pyrexia (9%), PPES (3%), chills (3%), fatigue (2%), and headache (2%). Table 3 and Table 4 present adverse reactions and laboratory abnormalities, respectively, of TAFINLAR as a single agent in the BREAK-3 study.

    TAFINLAR with Trametinib

    The safety of TAFINLAR when administered with trametinib was evaluated in 559 patients with previously untreated, unresectable or metastatic, BRAF V600E or V600K mutation-positive melanoma who received TAFINLAR in two trials, the COMBI-d study (n = 209) a multicenter, double-blind, randomized (1:1), active controlled trial and the COMBI-v study (n = 350) a multicenter, open-label, randomized (1:1), active controlled trial. In the COMBI-d and COMBI-v studies, patients received TAFINLAR 150 mg orally twice daily and trametinib 2 mg orally once daily until disease progression or unacceptable toxicity. Both trials excluded patients with abnormal LVEF, history of acute coronary syndrome within 6 months, history of Class II or greater congestive heart failure (New York Heart Association), history of retinal vein occlusion (RVO) or retinal pigment epithelial detachment (RPED), QTcB interval ≥ 480 msec, treatment refractory hypertension, uncontrolled arrhythmias, active brain metastases, or a known history of G6PD deficiency [see Clinical Studies (14.2)].

    Among these 559 patients, 199 (36%) were exposed to TAFINLAR for > 6 months to 12 months while 185 (33%) were exposed to TAFINLAR for ≥ 1 year. The median age was 55 years (range: 18 to 91), 57% were male, 98% were white, 72% had baseline ECOG performance status 0 and 28% had ECOG performance status 1, 64% had M1c stage disease, 35% had elevated lactate dehydrogenase (LDH) at baseline and 0.5% had a history of brain metastases.

    The most common adverse reactions (≥ 20%) for TAFINLAR in patients receiving TAFINLAR plus trametinib in the COMBI-d and COMBI-v studies were: pyrexia, rash, chills, headache, arthralgia, and cough. The demographics and baseline tumor characteristics of patients enrolled in the COMBI-d study are summarized in Clinical Studies [see Clinical Studies (14.2)]. Patients receiving TAFINLAR plus trametinib had a median duration of exposure of 11 months (range: 3 days to 30 months) to TAFINLAR. Among the 209 patients receiving TAFINLAR plus trametinib, 26% were exposed to TAFINLAR for > 6 months to 12 months while 46% were exposed to TAFINLAR for > 1 year.

    In the COMBI-d study, adverse reactions resulting in discontinuation of TAFINLAR occurred in 11% of patients receiving TAFINLAR plus trametinib; the most frequent was pyrexia (1.9%). Adverse reactions leading to dose reductions of TAFINLAR occurred in 26% of patients receiving TAFINLAR plus trametinib; the most frequent were pyrexia (14%), neutropenia (1.9%), rash (1.9%), and chills (1.9%). Adverse reactions leading to dose interruptions of TAFINLAR occurred in 56% of patients receiving TAFINLAR plus trametinib; the most frequent were pyrexia (35%), chills (11%), vomiting (7%), nausea (5%), and decreased ejection fraction (5%). 

    Table 5 and Table 6 present adverse reactions and laboratory abnormalities, respectively, observed in the COMBI-d study.

    Adjuvant Treatment of BRAF V600E or V600K Mutation-Positive Melanoma

    The safety of TAFINLAR when administered with trametinib was evaluated in 435 patients with Stage III melanoma with BRAF V600E or V600K mutations following complete resection who received at least one dose of study therapy in the COMBI-AD study [see Clinical Studies (14.3)]. Patients received TAFINLAR 150 mg orally twice daily and trametinib 2 mg orally once daily for 12 months. The trial excluded patients with abnormal left ventricular ejection fraction; history of acute coronary syndromes, coronary angioplasty, or stenting within 6 months; Class II or greater congestive heart failure (New York Heart Association); QTc interval ≥ 480 msec; treatment-refractory hypertension; uncontrolled arrhythmias; or history of retinal vein occlusion. The median age of patients who received TAFINLAR in combination with trametinib was 50 years (range: 18 to 89), 56% were male, 99% were white, 92% had baseline ECOG performance status 0, and 8% had baseline ECOG performance status of 1. Patients receiving TAFINLAR in combination with trametinib had a median duration of exposure of 11 months (range: 0 to 12) to TAFINLAR. Among the 435 patients receiving TAFINLAR in combination with trametinib, 71% were exposed to TAFINLAR for > 6 months.

    The most common adverse reactions (≥ 20%) in patients receiving TAFINLAR in combination with trametinib were: pyrexia, fatigue, nausea, headache, rash, chills, diarrhea, vomiting, arthralgia, and myalgia.

    Adverse reactions resulting in discontinuation, dose reduction, or dose interruption of TAFINLAR occurred in 25%, 35%, and 66% of patients, respectively; the most frequent for each were pyrexia and chills.

    Table 7 summarizes adverse reactions that occurred in at least 20% of patients receiving TAFINLAR in combination with trametinib.

    Metastatic, BRAF V600E-Mutation Positive Non-Small Cell Lung Cancer

    The safety of TAFINLAR when administered with trametinib was evaluated in 93 patients with previously untreated (n = 36) and previously treated (n = 57) metastatic BRAF V600E mutation-positive NSCLC in a multicenter, multi-cohort, non-randomized, open-label trial (Study BRF113928). Patients received TAFINLAR 150 mg orally twice daily and trametinib 2 mg orally once daily until disease progression or unacceptable toxicity. The trial excluded patients with abnormal left ventricular ejection fraction, history of acute coronary syndrome within 6 months, history of Class II or greater congestive heart failure (New York Heart Association), QTc interval ≥ 480 msec, treatment refractory hypertension, uncontrolled arrhythmias, active brain metastases, history of interstitial lung disease or pneumonitis, or history or current retinal vein occlusion [see Clinical Studies (14.4)].

    Among these 93 patients, 53 (57%) were exposed to TAFINLAR and trametinib for > 6 months and 27 (29%) were exposed to TAFINLAR and trametinib for ≥ 1 year. The median age was 65 years (range: 41 to 91); 46% were male; 85% were white; 32% had baseline ECOG performance status 0 and 61% had ECOG performance status 1; 98% had non-squamous histology; and 12% were current smokers, 60% were former smokers, and 28% had never smoked.

    The most common adverse reactions (≥ 20%) in these 93 patients were: pyrexia, fatigue, nausea, vomiting, diarrhea, dry skin, decreased appetite, edema, rash, chills, hemorrhage, cough, and dyspnea.

    Adverse reactions resulting in discontinuation of TAFINLAR occurred in 18% of patients; the most frequent were pyrexia (2.2%), decreased ejection fraction (2.2%), and respiratory distress (2.2%). Adverse reactions leading to dose reductions of TAFINLAR occurred in 35% of patients; the most frequent were pyrexia (10%), diarrhea (4.3%), nausea (4.3%), vomiting (4.3%), and neutropenia (3.2%). Adverse reactions leading to dose interruptions of TAFINLAR occurred in 62% of patients; the most frequent were pyrexia (27%), vomiting (11%), neutropenia (8%), and chills (6%).

    Locally Advanced or Metastatic, BRAF V600E-Mutation Positive Anaplastic Thyroid Cancer

    The safety of TAFINLAR when administered with trametinib was evaluated in a nine-cohort, multicenter, non-randomized, open-label study in patients with rare cancers with the BRAF V600E mutation, including locally advanced or metastatic ATC (Study BRF117019). At the time of the safety analysis, a total of 100 patients were enrolled in the trial, 16 of whom were enrolled in the ATC cohort. The primary safety population included all patients who received at least one dose of TAFINLAR or trametinib. Patients received TAFINLAR 150 mg orally twice daily and trametinib 2 mg orally once daily until disease progression or unacceptable toxicity.

    Among these 100 patients, 46 (46%) were exposed to TAFINLAR and trametinib for > 6 months and 23 (23%) were exposed to TAFINLAR and trametinib for ≥ 1 year. The median age was 59.5 years (range: 18 to 85); 62% were male; 85% were white; and 31% had baseline ECOG performance status 0 and 59% had ECOG performance status 1.

    The adverse reaction profile among all patients and among patients in the ATC cohort was similar to that observed in other approved indications.

  • 7       DRUG INTERACTIONS

    7.1       Effects of Other Drugs on TAFINLAR

    Strong inhibitors of CYP3A4 or CYP2C8 may increase the concentration of dabrafenib [see Clinical Pharmacology (12.3)]. Substitution of strong inhibitors of CYP3A4 or CYP2C8 is recommended during treatment with TAFINLAR. If concomitant use of strong inhibitors of CYP3A4 or CYP2C8 is unavoidable, monitor patients closely for adverse reactions when taking strong inhibitors.

    7.2       Effects of TAFINLAR on Other Drugs

    Dabrafenib decreased the systemic exposures of midazolam (a CYP3A4 substrate), S-warfarin (a CYP2C9 substrate), and R-warfarin (a CYP3A4/CYP1A2 substrate) [see Clinical Pharmacology (12.3)]. Monitor international normalized ratio (INR) levels more frequently in patients receiving warfarin during initiation or discontinuation of dabrafenib. Coadministration of TAFINLAR with other substrates of these enzymes, including dexamethasone or hormonal contraceptives, can result in decreased concentrations and loss of efficacy [see Use in Specific Populations (8.1, 8.3)]. Substitute for these medications or monitor patients for loss of efficacy if use of these medications is unavoidable.

    Risk Summary

    Based on findings from animal reproduction studies and its mechanism of action [see Clinical Pharmacology (12.1)], TAFINLAR can cause fetal harm when administered to a pregnant woman. There is insufficient data in pregnant women exposed to TAFINLAR to assess the risks. Dabrafenib was teratogenic and embryotoxic in rats at doses three times greater than the human exposure at the recommended clinical dose of 150 mg twice daily (see Data). Advise pregnant women of the potential risk to a fetus.

    In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%-4% and 15%-20%, respectively.

    Data

    Animal Data

    In a combined female fertility and embryo-fetal development study in rats conducted during the period of organogenesis, developmental toxicity consisted of embryo-lethality, ventricular septal defects, and variation in thymic shape at a dabrafenib dose of 300 mg/kg/day [approximately three times the human exposure at the recommended dose based on area under the curve (AUC)]. At doses of 20 mg/kg/day or greater (equivalent to the human exposure at the recommended dose based on AUC), rats demonstrated delays in skeletal development and reduced fetal body weight.

    8.2       Lactation

    Risk Summary

    There are no data on the presence of dabrafenib in human milk, or the effects of dabrafenib on the breastfed infant, or on milk production. Because of the potential for serious adverse reactions in breastfed infants, advise women not to breastfeed during treatment with TAFINLAR and for 2 weeks following the last dose.

    8.3       Females and Males of Reproductive Potential

    Pregnancy Testing

    Verify pregnancy status in females of reproductive potential prior to initiating TAFINLAR.

    Contraception

    Based on data from animal studies and its mechanism of action, TAFINLAR can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1)].

    Females

    Advise female patients of reproductive potential to use effective contraception during treatment with TAFINLAR and for 2 weeks after the last dose. Counsel patients to use a non-hormonal method of contraception since TAFINLAR can render hormonal contraceptives ineffective [see Drug Interactions (7.2)].

    Males

    To avoid potential drug exposure to pregnant partners and female partners of reproductive potential, advise male patients (including those who have had vasectomies) with female partners of reproductive potential to use condoms during treatment with TAFINLAR and for at least 2 weeks after the last dose.

    Infertility

    Females

    Advise female patients of reproductive potential that TAFINLAR may impair fertility. A reduction in fertility was observed in female rats at dose exposures equivalent to the human exposure at the recommended dose. A reduction in the number of corpora lutea was noted in pregnant rats at dose exposures approximately three times the human exposure at the recommended dose [see Nonclinical Toxicology (13.1)].

    Males

    Advise male patients of the potential risk for impaired spermatogenesis which may be irreversible. Effects on spermatogenesis have been observed in animals treated with dabrafenib at dose exposures up to three times the human exposure at the recommended dose [see Nonclinical Toxicology (13.1)].

    8.4       Pediatric Use

    The safety and effectiveness of TAFINLAR as a single agent or with trametinib have not been established in pediatric patients.

    Juvenile Animal Toxicity Data

    In a repeat-dose toxicity study in juvenile rats, an increased incidence of kidney cysts and tubular deposits were noted at doses as low as 0.2 times the human exposure at the recommended adult dose based on AUC. Additionally, forestomach hyperplasia, decreased bone length, and early vaginal opening were noted at doses as low as 0.8 times the human exposure at the recommended adult dose based on AUC.

    8.5       Geriatric Use

    Of the 586 patients with various solid tumors who received single agent TAFINLAR, 22% were aged 65 years and older. Of the 187 patients with melanoma who received single-agent TAFINLAR in the BREAK-3 study, 21% were aged 65 years or older [see Clinical Studies (14.1)]. No overall differences in the effectiveness or safety of TAFINLAR were observed between geriatric patients as compared to younger adults in the BREAK-3 study.

    Of the 994 patients with melanoma who received TAFINLAR plus trametinib in the COMBI-d, COMBI-v, and COMBI-AD studies [see Clinical Studies (14.2, 14.3)], 21% were aged 65 years and older and 5% were aged 75 years and older. No overall differences in the effectiveness of TAFINLAR plus trametinib were observed between geriatric patients as compared to younger adults across these melanoma studies. The incidences of peripheral edema (26% vs. 12%) and anorexia (21% vs. 9%) were increased in geriatric patients as compared to younger adults in these studies.

    Of the 171 patients with NSCLC who received TAFINLAR in Study BRF113928, there were insufficient numbers of geriatric patients to determine whether they respond differently from younger adults [see Clinical Studies (14.4)].

    Of the 26 patients with ATC who received TAFINLAR in Study BRF117019, 77% were aged 65 years and older, and 31% were aged 75 years and older [see Clinical Studies (14.5)]. This study in ATC did not include sufficient numbers of younger adults to determine whether they respond differently compared to geriatric patients.

    8.6       Renal Impairment

    Dose adjustment is not recommended for patients with mild (GFR 60 to 89 mL/min/1.73 m2) or moderate (GFR 30 to 59 mL/min/1.73 m2) renal impairment. An appropriate dose has not been established for patients with severe (GFR ≤ 30 mL/min/1.73 m2) renal impairment [see Clinical Pharmacology (12.3)].

    8.7       Hepatic Impairment

    Dose adjustment is not recommended for patients with mild (bilirubin ≤ upper limit of normal (ULN) and alanine aminotransferase (AST) > ULN or bilirubin > 1x to 1.5x ULN and any AST) hepatic impairment. As hepatic metabolism and biliary secretion are the primary routes of elimination of dabrafenib and its metabolites, patients with moderate (bilirubin > 1.5x to 3x ULN and any AST) to severe (bilirubin > 3x to 10x ULN and any AST) hepatic impairment may have increased exposure. An appropriate dose has not been established for patients with moderate to severe hepatic impairment [see Clinical Pharmacology (12.3)].

  • 10       OVERDOSAGE

    There is no information on overdosage of TAFINLAR. Since dabrafenib is highly bound to plasma proteins, hemodialysis is likely to be ineffective in the treatment of overdose with TAFINLAR.

  • 12       CLINICAL PHARMACOLOGY

    12.1       Mechanism of Action

    Dabrafenib is an inhibitor of some mutated forms of BRAF kinases with in vitro IC50 values of 0.65, 0.5, and 1.84 nM for BRAF V600E, BRAF V600K, and BRAF V600D enzymes, respectively. Dabrafenib also inhibits wild-type BRAF and CRAF kinases with IC50 values of 3.2 and 5.0 nM, respectively, and other kinases such as SIK1, NEK11, and LIMK1 at higher concentrations. Some mutations in the BRAF gene, including those that result in BRAF V600E, can result in constitutively activated BRAF kinases that may stimulate tumor cell growth [see Indications and Usage (1)]. Dabrafenib inhibits cell growth of various BRAF V600 mutation-positive tumors in vitro and in vivo.

    Dabrafenib and trametinib target two different kinases in the RAS/RAF/MEK/ERK pathway. Use of dabrafenib and trametinib in combination resulted in greater growth inhibition of BRAF V600 mutation-positive tumor cell lines in vitro and prolonged inhibition of tumor growth in BRAF V600 mutation positive tumor xenografts compared with either drug alone.

    12.2       Pharmacodynamics

    Cardiac Electrophysiology

    The potential effect of TAFINLAR on QT interval was assessed in a dedicated multiple-dose study in 32 patients with BRAF V600 mutation-positive tumors. No large changes in the mean QT interval (i.e., > 20 ms) were detected with dabrafenib 300 mg administered twice daily (two times the recommended dosage).

    In clinical trials, QTc (heart rate-corrected QT) prolongation to ≥ 500 ms occurred in 0.8% (2/264) of patients receiving TAFINLAR plus trametinib and in 1.5% (4/264) of patients receiving TAFINLAR as a single agent. The QTc was increased > 60 ms from baseline in 3.8% (10/264) of patients receiving TAFINLAR plus trametinib and 3% (8/264) of patients treated with TAFINLAR as a single agent. 

    12.3       Pharmacokinetics

    Absorption

    After oral administration, median time to achieve peak plasma concentration (Tmax) is 2 hours. Mean absolute bioavailability of oral dabrafenib is 95%. Following a single dose, dabrafenib exposure (Cmax and AUC) increased in a dose-proportional manner across the dose range of 12 mg to 300 mg, but the increase was less than dose-proportional after repeat twice-daily dosing. After repeat twice-daily dosing of 150 mg, the mean accumulation ratio was 0.73, and the inter-subject variability (CV%) of AUC at steady-state was 38%.

    Effect of Food

    Administration of dabrafenib with a high-fat meal (approximately 1000 calories, 58-75 grams fat, 58 grams carbohydrates, and 33 grams protein) decreased Cmax by 51%, decreased AUC by 31%, and delayed median Tmax by 3.6 hours as compared with the fasted state.

    Distribution

    Dabrafenib is 99.7% bound to human plasma proteins. The apparent volume of distribution (Vc/F) is 70.3 L.

    Elimination

    The mean terminal half-life of dabrafenib is 8 hours after oral administration. Hydroxy-dabrafenib terminal half-life (10 hours) parallels that of dabrafenib while the carboxy- and desmethyl-dabrafenib metabolites exhibit longer half-lives (21 to 22 hours). The apparent clearance of dabrafenib is 17.0 L/h after single dosing and 34.4 L/h after 2 weeks of twice-daily dosing.

    Metabolism

    The metabolism of dabrafenib is primarily mediated by CYP2C8 and CYP3A4 to form hydroxy-dabrafenib. Hydroxy-dabrafenib is further oxidized via CYP3A4 to form carboxy-dabrafenib and subsequently excreted in bile and urine. Carboxy-dabrafenib is decarboxylated to form desmethyl-dabrafenib; desmethyl-dabrafenib may be reabsorbed from the gut. Desmethyl-dabrafenib is further metabolized by CYP3A4 to oxidative metabolites. Mean metabolite-to-parent AUC ratios following repeat-dose administration are 0.9, 11, and 0.7 for hydroxy-, carboxy-, and desmethyl-dabrafenib, respectively. Based on systemic exposure, relative potency, and pharmacokinetic properties, both hydroxy- and desmethyl-dabrafenib are likely to contribute to the clinical activity of dabrafenib.

    Excretion

    Fecal excretion is the major route of elimination accounting for 71% of radioactive dose while urinary excretion accounted for 23% of total radioactivity as metabolites only.

    Specific Populations

    Age, Body Weight, and Sex

    Age has no effect on dabrafenib pharmacokinetics. Pharmacokinetic differences based on sex and on weight are not clinically relevant.

    Patients with Renal Impairment

    The pharmacokinetics of dabrafenib were evaluated using a population analysis in 233 patients with mild renal impairment (GFR 60 to 89 mL/min/1.73 m2) and 30 patients with moderate renal impairment (GFR 30 to 59 mL/min/1.73 m2) enrolled in clinical trials. Mild or moderate renal impairment has no effect on systemic exposure to dabrafenib and its metabolites. No data are available in patients with severe renal impairment.

    Patients with Hepatic Impairment

    The pharmacokinetics of dabrafenib was evaluated using a population analysis in 65 patients with mild (bilirubin ≤ ULN and AST > ULN or bilirubin > 1x to 1.5x ULN and any AST) hepatic impairment enrolled in clinical trials. Mild hepatic impairment has no effect on systemic exposure to dabrafenib and its metabolites. No data are available in patients with moderate (bilirubin > 1.5x to 3x ULN and any AST) to severe (bilirubin > 3x to 10x ULN and any AST) hepatic impairment.

    Drug Interaction Studies

    Effect of Trametinib on Dabrafenib: Coadministration of trametinib 2 mg daily with dabrafenib 150 mg twice daily resulted in a 23% increase in AUC of dabrafenib, a 33% increase in AUC of desmethyl-dabrafenib, and no change in AUC of hydroxy-dabrafenib as compared with administration of dabrafenib.

    Effect of Strong Inhibitors of CYP3A4 or CYP2C8 on Dabrafenib: Coadministration of dabrafenib 75 mg twice daily and ketoconazole 400 mg once daily (a strong CYP3A4 inhibitor) for 4 days increased dabrafenib AUC by 71%, hydroxy-dabrafenib AUC by 82%, and desmethyl-dabrafenib AUC by 68%. Coadministration of dabrafenib 75 mg twice daily and gemfibrozil 600 mg twice daily (a strong CYP2C8 inhibitor) for 4 days increased dabrafenib AUC by 47%, with no change in the AUC of dabrafenib metabolites.

    Effect of Strong Inducers of CYP3A4 or Moderate Inducers CYP2C8 on Dabrafenib: Coadministration of dabrafenib 150 mg twice daily and rifampin 600 mg once daily (a strong CYP3A4 and moderate CYP2C8 inducer) for 10 days decreased dabrafenib AUC by 34%, had no effect on hydroxy-dabrafenib AUC, and decreased desmethyl-dabrafenib AUC by 30%.

    Effect of Acid Reducing Agents on Dabrafenib: Coadministration of dabrafenib 150 mg twice daily and rabeprazole 40 mg once daily for 4 days resulted in a 3% increase in AUC of dabrafenib, a 15% decrease in AUC of desmethyl-dabrafenib, and a 5% increase in AUC of hydroxy-dabrafenib as compared to administration of dabrafenib alone. The changes in exposure of dabrafenib and its metabolites were not clinically relevant.

    Effect of Dabrafenib on CYP Substrates: In vitro data demonstrate that dabrafenib is an inducer of CYP3A4 and CYP2B6 via activation of the pregnane X receptor (PXR) and constitutive androstane receptor (CAR) nuclear receptors. Dabrafenib may also induce CYP2C enzymes via the same mechanism. Coadministration of TAFINLAR 150 mg twice daily for 15 days and a single dose of midazolam 3 mg (a CYP3A4 substrate) decreased midazolam AUC by 65%. Coadministration of dabrafenib 150 mg twice daily for 15 days and a single dose of warfarin 15 mg decreased the AUC of S-warfarin (a CYP2C9 substrate) by 37% and the AUC of R-warfarin (CYP3A4/CYP1A2 substrate) by 33%.

    Effect of Transporters on Dabrafenib: Dabrafenib and its metabolites, hydroxyl-dabrafenib and desmethyl-dabrafenib, are substrates of human P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP), but are not substrates of organic cation transporter (OCT1) or organic anion transporting polypeptide (OATP1A2, OATP1B1, OATP1B3, OATP2B1) in vitro.

    Effect of Dabrafenib on Transporters: Dabrafenib and its metabolites, hydroxy-dabrafenib, carboxy-dabrafenib, and desmethyl-dabrafenib, are inhibitors of OATP1B1, OATP1B3, and organic anion transporter (OAT1 and OAT3) in vitro. Dabrafenib and desmethyl-dabrafenib are inhibitors of OCT2 and BCRP in vitro. Coadministration of TAFINLAR 150 mg twice daily with a single dose of rosuvastatin (a sensitive OATP1B1 and OATP1B3 substrate) increased rosuvastatin Cmax by 2.6-fold, but did not change its AUC.

  • 13       NONCLINICAL TOXICOLOGY

    13.1       Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenicity studies with dabrafenib have not been conducted. TAFINLAR increased the risk of cutaneous squamous cell carcinomas in patients in clinical trials.

    Dabrafenib was not mutagenic in vitro in the bacterial reverse mutation assay (Ames test) or the mouse lymphoma assay, and was not clastogenic in an in vivo rat bone marrow micronucleus test.

    In a combined female fertility and embryo-fetal development study in rats, a reduction in fertility was noted at doses greater than or equal to 20 mg/kg/day (equivalent to the human exposure at the recommended dose based on AUC). A reduction in the number of ovarian corpora lutea was noted in pregnant females at 300 mg/kg/day (which is approximately three times the human exposure at the recommended dose based on AUC).

    Male fertility studies with dabrafenib have not been conducted; however, in repeat-dose studies, testicular degeneration/depletion was seen in rats and dogs at doses equivalent to and three times the human exposure at the recommended dose based on AUC, respectively. 

    13.2       Animal Toxicology and/or Pharmacology

    Adverse cardiovascular effects were noted in dogs at dabrafenib doses of 50 mg/kg/day (approximately five times the human exposure at the recommended dose based on AUC) or greater, when administered for up to 4 weeks. Adverse effects consisted of coronary arterial degeneration/necrosis and hemorrhage, as well as cardiac atrioventricular valve hypertrophy/hemorrhage.

    14.1       BRAF V600E Mutation-Positive Unresectable or Metastatic Melanoma – TAFINLAR as a Single Agent

    BREAK-3 Study

    The safety and efficacy of TAFINLAR as a single agent were evaluated in an international, multicenter, randomized (3:1), open-label, active-controlled trial (the BREAK-3 study; NCT01227889) conducted in 250 patients with previously untreated BRAF V600E mutation-positive, unresectable or metastatic melanoma. Patients with any prior use of BRAF inhibitors or MEK inhibitors were excluded. Patients were randomized to receive TAFINLAR 150 mg orally twice daily (n = 187) or dacarbazine 1000 mg/m2 intravenously every 3 weeks (n = 63). Randomization was stratified by disease stage at baseline [unresectable Stage III (regional nodal or in-transit metastases), M1a (distant skin, subcutaneous, or nodal metastases), or M1b (lung metastases) versus M1c melanoma (all other visceral metastases or elevated serum LDH)]. The main efficacy outcome measure was progression-free survival (PFS) as assessed by the investigator. In addition, an independent radiology review committee (IRRC) assessed the following efficacy outcome measures in pre-specified supportive analyses: PFS, confirmed overall response rate (ORR), and duration of response (DoR).

    The median age of patients in the BREAK-3 study was 52 years. The majority of the trial population was male (60%), white (99%), had an ECOG performance status of 0 (67%), M1c disease (66%), and normal LDH (62%). All patients had tumor tissue with mutations in BRAF V600E as determined by a clinical trial assay at a centralized testing site. Tumor samples from 243 patients (97%) were tested retrospectively, using an FDA-approved companion diagnostic test, THxID™-BRAF assay.

    The median durations of follow-up prior to initiation of alternative treatment in patients randomized to receive TAFINLAR was 5.1 months and in the dacarbazine arm was 3.5 months. Twenty-eight (44%) patients crossed over from the dacarbazine arm at the time of disease progression to receive TAFINLAR.

    The BREAK-3 study demonstrated a statistically significant increase in progression-free survival in the patients treated with TAFINLAR. Table 11 and Figure 1 summarize the PFS results.

    BREAK-MB Study

    The activity of TAFINLAR for the treatment of BRAF V600E mutation-positive melanoma, metastatic to the brain was evaluated in a single-arm, open-label, two-cohort multicenter trial (the BREAK-MB study; NCT01266967). All patients received TAFINLAR 150 mg twice daily. Patients in Cohort A (n = 74) had received no prior local therapy for brain metastases, while patients in Cohort B (n = 65) had received at least one local therapy for brain metastases, including, but not limited to, surgical resection, whole brain radiotherapy, or stereotactic radiosurgery such as gamma knife, linear-accelerated-based radiosurgery, or charged particles. In addition, patients in Cohort B were required to have evidence of disease progression in a previously treated lesion or an untreated lesion. Additional eligibility criteria were at least one measurable lesion of 0.5 cm or greater in largest diameter on contrast-enhanced MRI, stable or decreasing corticosteroid dose, and no more than two prior systemic regimens for treatment of metastatic disease. The major efficacy outcome measure was estimation of the overall intracranial response rate (OIRR) in each cohort.

    The median age of patients in Cohort A was 50 years, 72% were male, 100% were white, 59% had a pre-treatment ECOG performance status of 0, and 57% had an elevated LDH value at baseline. The median age of patients in Cohort B was 51 years, 63% were male, 98% were white, 66% had a pre-treatment ECOG performance status of 0, and 54% had an elevated LDH value at baseline. The intracranial response rate as determined by an independent radiology review committee, masked to investigator response assessments, was 18% (95% CI: 10%, 28%) in Cohort A and 18% (95% CI: 10%, 30%) in Cohort B. The median duration of intracranial response was 4.6 months in both cohorts.

    14.2       BRAF V600E or V600K Unresectable or Metastatic Melanoma – TAFINLAR with Trametinib

    COMBI-d Study and COMBI-v Study

    The safety and efficacy of TAFINLAR administered with trametinib were evaluated in two international, randomized, active-controlled trials: one double-blind trial (the COMBI-d study; NCT01584648) and one open-label trial (the COMBI-v study; NCT01597908). 

    The COMBI-d study compared TAFINLAR and trametinib to TAFINLAR and placebo as first-line therapy for patients with unresectable (Stage IIIC) or metastatic (Stage IV) BRAF V600E or V600K mutation-positive cutaneous melanoma. Patients were randomized (1:1) to receive TAFINLAR 150 mg twice daily and trametinib 2 mg once daily or TAFINLAR 150 mg twice daily plus matching placebo. Randomization was stratified by LDH level (> ULN vs. ≤ ULN) and BRAF mutation subtype (V600E vs. V600K). The major efficacy outcome was investigator-assessed progression-free survival (PFS) per RECIST v1.1 with additional efficacy outcome measures of overall survival (OS) and confirmed overall response rate (ORR).

    The COMBI-v study compared TAFINLAR and trametinib to vemurafenib as first-line treatment therapy for patients with unresectable (Stage IIIC) or metastatic (Stage IV) BRAF V600E or V600K mutation-positive cutaneous melanoma. Patients were randomized (1:1) to receive TAFINLAR 150 mg twice daily and trametinib 2 mg once daily or vemurafenib 960 mg twice daily. Randomization was stratified by lactate dehydrogenase (LDH) level (> ULN vs. ≤ ULN) and BRAF mutation subtype (V600E vs. V600K). The major efficacy outcome measure was overall survival. Additional efficacy outcome measures were PFS and ORR as assessed by investigator per RECIST v1.1.

    In the COMBI-d study, 423 patients were randomized to TAFINLAR plus trametinib (n = 211) or TAFINLAR plus placebo (n = 212). The median age was 56 years (range: 22 to 89 years), 53% were male, > 99% were white, 72% had ECOG performance status of 0, 4% had Stage IIIC, 66% had M1c disease, 65% had a normal LDH, and 2 patients had a history of brain metastases. All patients had tumor containing BRAF V600E or V600K mutations as determined by centralized testing, 85% with BRAF V600E mutations and 15% with BRAF V600K mutations.

    In the COMBI-v study, 704 patients were randomized to TAFINLAR plus trametinib (n = 352) or single-agent vemurafenib (n = 352). The median age was 55 years (range: 18 to 91 years), 96% were white, and 55% were male, 6% percent of patients had Stage IIIC, 61% had M1c disease, 67% had a normal LDH, 70% had ECOG performance status of 0, 89% had BRAF V600E mutation-positive melanoma, and one patient had a history of brain metastases.

    The COMBI-d and COMBI-v studies demonstrated statistically significant improvements in OS and PFS. Table 12 and Figures 2 and 3 summarize the efficacy results.

    COMBI-MB Study

    The activity of TAFINLAR with trametinib for the treatment of BRAF V600E or V600K mutation-positive melanoma, metastatic to the brain, was evaluated in a non-randomized, open-label, multi-center, multi-cohort trial (the COMBI-MB study; NCT02039947). Eligible patients were required to have at least one measurable intracranial lesion and to have no leptomeningeal disease, parenchymal brain metastasis greater than 4 cm in diameter, ocular melanoma, or primary mucosal melanoma. Patients received TAFINLAR 150 mg orally twice daily and trametinib 2 mg orally once daily until disease progression or unacceptable toxicity. The major efficacy outcome measure was intracranial response rate, defined as the percentage of patients with a confirmed intracranial response per RECIST v1.1, modified to allow up to five intracranial target lesions at least 5 mm in diameter, as assessed by independent review.

    The COMBI-MB study enrolled 121 patients with a BRAF V600E (85%) or V600K (15%) mutation. The median age was 54 years (range: 23 to 84 years), 58% were male, 100% were white, 8% were from the United States, 65% had a normal LDH value at baseline, and 97% had an ECOG performance status of 0 or 1. Intracranial metastases were asymptomatic in 87% and symptomatic in 13% of patients, 22% received prior local therapy for brain metastases, and 87% also had extracranial metastases.

    The intracranial response rate was 50% (95% CI: 41, 60), with a complete response rate of 4.1% and a partial response rate of 46%. The median duration of intracranial response was 6.4 months (range: 1 to 31 months). Of the patients with an intracranial response, 9% had stable or progressive disease as their best overall response.

    14.3       Adjuvant Treatment of BRAF V600E or V600K Mutation-Positive Melanoma

    COMBI-AD (NCT 01682083) was an international, multi-center, randomized, double-blind, placebo-controlled trial that enrolled patients with Stage III melanoma with BRAF V600E or V600K mutations as detected by the THxID-BRAF assay and pathologic involvement of regional lymph node(s). Patients were randomized (1:1) to receive TAFINLAR 150 mg twice daily and trametinib 2 mg once daily or two placebos for up to 1 year. Enrollment required complete resection of melanoma with complete lymphadenectomy within 12 weeks prior to randomization. The trial excluded patients with mucosal or ocular melanoma, unresectable in-transit metastases, distant metastatic disease, or prior systemic anticancer treatment, including radiotherapy. Randomization was stratified by BRAF mutation status (V600E or V600K) and American Joint Committee on Cancer (AJCC; 7th Edition) stage (IIIa, IIIb, or IIIc). The major efficacy outcome measure was relapse-free survival (RFS), defined as the time from randomization to disease recurrence (local, regional, or distant metastasis), new primary melanoma, or death from any cause, whichever occurred first as assessed by the investigator. Patients underwent imaging for tumor recurrence every 3 months for the first two years and every 6 months thereafter.

    In COMBI-AD, a total of 870 patients were randomized: 438 to TAFINLAR in combination with trametinib and 432 to placebo. Median age was 51 years (range 18-89), 55% were male, 99% were white, and 91% had an ECOG performance status of 0. Disease characteristics were AJCC Stage IIIa (18%), Stage IIIb (41%), Stage IIIc (40%), stage unknown (1%); BRAF V600E mutation (91%), BRAF V600K mutation (9%); macroscopic lymph nodes (65%); and tumor ulceration (41%). The median duration of follow-up (time from randomization to last contact or death) was 2.8 years.

    COMBI-AD showed a statistically significant improvement in RFS in patients randomized to TAFINLAR in combination with trametinib compared to those randomized to placebo. Efficacy results are presented in Table 13 and Figure 4.

    14.4       BRAF V600E Mutation-Positive Metastatic Non-Small Cell Lung Cancer

    The safety and efficacy of TAFINLAR alone or administered with trametinib were evaluated in a multi-center, three-cohort, non-randomized, activity-estimating, open-label trial (Study BRF113928, NCT01336634). Key eligibility criteria were locally confirmed BRAF V600E mutation-positive metastatic NSCLC, no prior exposure to BRAF or MEK-inhibitor, and absence of EGFR mutation or ALK rearrangement (unless patients had progression on prior tyrosine kinase inhibitor therapy). Patients enrolled in Cohorts A and B were required to have received at least one previous platinum based chemotherapy regimen for NSCLC with demonstrated disease progression but no more than three prior systemic regimens. Patients enrolled in Cohort C could not have received prior systemic therapy for metastatic NSCLC. Patients in Cohort A received TAFINLAR 150 mg twice daily. Patients in Cohorts B and C received TAFINLAR 150 mg twice daily and trametinib 2 mg once daily. The major efficacy outcome measure was overall response rate (ORR) per RECIST v1.1 as assessed by independent review committee (IRC) and DoR.

    There were a total of 171 patients enrolled which included 78 patients enrolled in Cohort A, 57 patients enrolled in Cohort B, and 36 patients enrolled in Cohort C. The characteristics of the study population were a median age of 66 years, 48% male; 81% white, 14% Asian, 3% black, and 2% Hispanic; 60% were former smokers, 32% were never smokers, and 8% current smokers; 27% had ECOG performance status (PS) 0, 63% had ECOG PS 1, and 11% had ECOG PS of 2; 99% had metastatic disease of which 6% had brain metastasis at baseline and 14% had liver metastasis at baseline; 11% had systemic anti-cancer therapy in the adjuvant setting and 58% of the 135 previously treated patients had only one line of prior systemic therapy for metastatic disease; and 98% had non-squamous histology.

    Efficacy results are summarized in Table 14.

    In a subgroup analysis of patients with retrospectively, centrally confirmed BRAF V600E mutation-positive NSCLC with the Oncomine Dx Target Test, the ORR results were similar to those presented in Table 14.

    14.5       BRAF V600E Mutation-Positive Locally Advanced or Metastatic Anaplastic Thyroid Cancer

    The safety and efficacy of TAFINLAR administered with trametinib was evaluated in an activity estimating, nine-cohort, multi-center, non-randomized, open-label trial (Study BRF117019; NCT02034110) in patients with rare cancers with the BRAF V600E mutation, including locally advanced, unresectable, or metastatic ATC with no standard locoregional treatment options. Trial BRF117019 excluded patients who could not swallow or retain the medication; who received prior treatment with BRAF or MEK inhibitors; with symptomatic or untreated CNS metastases; or who had airway obstruction. Patients received TAFINLAR 150 mg twice daily and trametinib 2 mg once daily. The major efficacy outcome measure was overall response rate (ORR) per RECIST v1.1 as assessed by independent review committee (IRC) and DoR.

    At the time of efficacy analysis, 23 patients were evaluable for response in the ATC cohort. Three additional patients were enrolled; however, there was insufficient time to assess response of these patients. Among the 26 patients enrolled, the median age was 70 years (range: 49-85); 50% were male, 50% white, 46% Asian; 100% had ECOG performance status of 0 or 1; and 54% had a prior history of differentiated thyroid cancer. Prior anti-cancer treatments included surgery (92%), external beam radiotherapy (81%), and systemic therapy (54%).

    Efficacy results are summarized in Table 15.

    (dabrafenib)
    capsules
    Important information: If your healthcare provider prescribes TAFINLAR for you to be taken with trametinib, also read the Patient Information leaflet that comes with trametinib.
    What is the most important information I should know about TAFINLAR?
    TAFINLAR may cause serious side effects, including:
    Risk of new cancers. TAFINLAR, when used alone or with trametinib, may cause skin cancers,
    called cutaneous squamous cell carcinoma, keratoacanthoma, basal cell carcinoma, or melanoma.
    Talk with your healthcare provider about your risk for these cancers.
    Check your skin and tell your healthcare provider right away about any skin changes including a:
    • new wart
    • skin sore or reddish bump that bleeds or does not heal
    • change in size or color of a mole
    Your healthcare provider should check your skin before treatment with TAFINLAR, every 2 months during treatment with TAFINLAR, and for up to 6 months after you stop taking TAFINLAR to look for any new skin cancers.
    Your healthcare provider should also check for cancers that may not occur on the skin. Tell your healthcare provider about any new symptoms that develop during treatment with TAFINLAR.
    See "What are the possible side effects of TAFINLAR?" for more information about side effects.
    What is TAFINLAR?
    TAFINLAR is a prescription medicine used:
    • alone or in combination with a medicine called trametinib to treat a type of skin cancer called melanoma:
      ○ that has spread to other parts of the body or cannot be removed by surgery, and 
      ○ that has a certain type of abnormal “BRAF” gene.
    • in combination with trametinib, to help prevent melanoma that has a certain type of abnormal “BRAF” gene from coming back after the cancer has been removed by surgery.
    • in combination with trametinib to treat a type of lung cancer called non-small cell lung cancer (NSCLC):
      ○ that has spread to other parts of the body, and 
      ○ that has a certain type of abnormal “BRAF” gene.
    • in combination with trametinib to treat a type of thyroid cancer called anaplastic thyroid cancer (ATC):
      ○ that has spread to other parts of the body and you have no satisfactory treatment options and 
      ○ that has a certain type of abnormal “BRAF” gene
    TAFINLAR should not be used to treat people with wild-type BRAF melanoma, wild-type BRAF NSCLC, or wild-type BRAF ATC.
    Your healthcare provider will perform a test to make sure that TAFINLAR is right for you.
    It is not known if TAFINLAR alone or TAFINLAR with trametinib is safe and effective in children.
    Before you take TAFINLAR, tell your healthcare provider about all of your medical conditions, including if you:
    • have had bleeding problems
    • have heart problems
    • have eye problems
    • have liver or kidney problems
    • have diabetes
    • plan to have surgery, dental, or other medical procedures
    • have a deficiency of the glucose-6-phosphate dehydrogenase (G6PD) enzyme
    • are a male (including one who has had a vasectomy) with a female partner of reproductive potential
      ○ Males (including those who have had a vasectomy) should use condoms during sexual intercourse during treatment with TAFINLAR and for at least 2 weeks after the last dose of TAFINLAR
    • are pregnant or plan to become pregnant. TAFINLAR can harm your unborn baby.
      ○ Females who are able to become pregnant should use effective birth control (contraception) during treatment with TAFINLAR and for 2 weeks after the last dose of TAFINLAR.
      ○ Birth control methods that contain hormones (such as birth control pills, injections, or transdermal systems) may not work as well during treatment with TAFINLAR. You should use another effective method of birth control during treatment with TAFINLAR.
      ○ Talk to your healthcare provider about birth control methods that may be right for you during this time.
      ○ Tell your healthcare provider right away if you become pregnant or think you might be pregnant during treatment with TAFINLAR.
    • are breastfeeding or plan to breastfeed. It is not known if TAFINLAR passes into your breast milk.
      ○ Do not breastfeed during treatment and for 2 weeks after your last dose of TAFINLAR. Talk to your healthcare provider about the best way to feed your baby during this time.
    Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.
    How should I take TAFINLAR?
    • Take TAFINLAR exactly as your healthcare provider tells you. Do not change your dose or stop TAFINLAR unless your healthcare provider tells you.
    • Your healthcare provider may change your dose of TAFINLAR, temporarily stop, or completely stop your treatment with TAFINLAR if you develop certain side effects.
    • Take TAFINLAR 2 times a day, about 12 hours apart.
    • Take TAFINLAR at least 1 hour before or 2 hours after a meal.
    • Do not open, crush, or break TAFINLAR capsules.
    • If you miss a dose of TAFINLAR, take it as soon as you remember. If it is within 6 hours of your next scheduled dose, just take your next dose at your regular time. Do not make up for the missed dose.
    What are the possible side effects of TAFINLAR?
    TAFINLAR may cause serious side effects, including:
    • See “What is the most important information I should know about TAFINLAR?”
    • bleeding problems. TAFINLAR, when taken with trametinib, can cause serious bleeding problems, especially in your brain or stomach, that can lead to death. Call your healthcare provider and get medical help right away if you have any signs of bleeding, including:
      ○ headaches, dizziness, or feeling weak
      ○ cough up blood or blood clots
      ○ vomit blood or your vomit looks like “coffee grounds”
      ○ red or black stool that looks like tar

      ○ see color dots
      ○ halo (see blurred outline around objects)
      ○ eye pain, swelling, or redness
    • fever. Fever is common during treatment with TAFINLAR, but may also be serious. When taking TAFINLAR with trametinib, fever may happen more often or may be more severe. In some cases, chills or shaking chills, too much fluid loss (dehydration), low blood pressure, dizziness, or kidney problems may happen with the fever. Call your healthcare provider right away if you get a fever during treatment with TAFINLAR.
    • serious skin reactions. Rash is a common side effect of TAFINLAR. TAFINLAR can also cause other skin reactions. In some cases these rashes and other skin reactions can be severe or serious, and may need to be treated in a hospital. Call your healthcare provider if you get any of the following symptoms:
      ○ skin rash that bothers you or does not go away
      ○ acne
      ○ redness, swelling, peeling, or tenderness of hands or feet
      ○ skin redness
    • increased blood sugar (hyperglycemia). Some people may develop high blood sugar or worsening diabetes during treatment with TAFINLAR. If you are diabetic, your healthcare provider should check your blood sugar levels closely during treatment with TAFINLAR. Your diabetes medicine may need to be changed. Tell your healthcare provider if you have any of the following symptoms of severe high blood sugar:
      ○ increased thirst
      ○ urinating more often than normal, or urinating an increased amount of urine
    • TAFINLAR may cause healthy red blood cells to break down too early in people with G6PD deficiency. This may lead to a type of anemia called hemolytic anemia where the body does not have enough healthy red blood cells. Tell your healthcare provider if you have any of the following signs or symptoms:
      ○ yellow skin (jaundice)
      ○ weakness or dizziness
