  • 5       WARNINGS AND PRECAUTIONS

    5.1       New Primary Malignancies

    Cutaneous Malignancies

    In the COMBI-d study in patients with unresectable or metastatic melanoma, the incidence of basal cell carcinoma in patients receiving MEKINIST and dabrafenib was 3.3%. Among the 7 patients receiving MEKINIST with dabrafenib who developed basal cell carcinoma, 2 experienced more than one occurrence (range: 1 to 3). Cutaneous squamous cell carcinomas and keratoacanthoma (cuSCC) and new primary melanoma occurred in 3% and 0.5% of patients receiving MEKINIST and dabrafenib, 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 MEKINIST plus dabrafenib, respectively.

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

    Perform dermatologic evaluations prior to initiation of MEKINIST when used with dabrafenib, every 2 months while on therapy, and for up to 6 months following discontinuation of the combination. No dose modifications of MEKINIST are recommended in patients who develop new primary cutaneous malignancies.

    Non-Cutaneous Malignancies

    Based on its mechanism of action, dabrafenib may promote growth and development of malignancies with activation of RAS through mutation or other mechanisms [refer to the Full Prescribing Information for dabrafenib]. In the COMBI-d, COMBI-AD, and BRF113928 studies, non-cutaneous malignancies occurred in 1.4%, 1%, and 1.1% of patients receiving MEKINIST plus dabrafenib, respectively.

    Monitor patients receiving MEKINIST and dabrafenib closely for signs or symptoms of non-cutaneous malignancies. No dose modification is required for MEKINIST in patients who develop non-cutaneous malignancies.

    5.2       Hemorrhage

    Hemorrhages, including major hemorrhages defined as symptomatic bleeding in a critical area or organ, can occur with MEKINIST.

    In the COMBI-d study, the incidence of hemorrhagic events in patients receiving MEKINIST and dabrafenib was 19%. Gastrointestinal hemorrhage occurred in 6% of patients receiving MEKINIST in combination with dabrafenib. In the COMBI-d study, 1.4% of patients receiving MEKINIST and dabrafenib developed fatal intracranial hemorrhage. No fatal hemorrhagic events were observed in the COMBI-AD study. In Study BRF113928, fatal hemorrhagic events occurred in 2.2% of patients receiving MEKINIST with dabrafenib; these events were retroperitoneal hemorrhage and subarachnoid hemorrhage.

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

    5.3       Colitis and Gastrointestinal Perforation

    Colitis and gastrointestinal perforation, including fatal outcomes, have been reported in patients taking MEKINIST as a single-agent and when administered with dabrafenib. Across clinical trials of MEKINIST, colitis occurred in 0.6% of patients and gastrointestinal perforation occurred in 0.3% of patients.

    Monitor patients closely for colitis and gastrointestinal perforations.

    5.4       Venous Thromboembolism

    In the COMBI-d study, deep venous thrombosis (DVT) and pulmonary embolism (PE) occurred in 2.8% of patients receiving MEKINIST and dabrafenib. In the COMBI-AD study, DVT and PE occurred in 2% of patients receiving MEKINIST and dabrafenib. In Study BRF113928, DVT and PE occurred in 4.3% of patients receiving MEKINIST and dabrafenib.

    Advise patients to immediately seek medical care if they develop symptoms of DVT or PE, such as shortness of breath, chest pain, or arm or leg swelling. Permanently discontinue MEKINIST for life threatening PE. Withhold MEKINIST for uncomplicated DVT and PE for up to 3 weeks; if improved, MEKINIST may be resumed at a lower dose level [see Dosage and Administration (2.7)].

    5.5       Cardiomyopathy

    Cardiomyopathy, including cardiac failure, can occur with MEKINIST.

    In the METRIC study in patients with unresectable or metastatic melanoma, cardiomyopathy [defined as cardiac failure, left ventricular dysfunction, or decreased left ventricular ejection fraction (LVEF)] occurred in 7% of patients receiving MEKINIST; no chemotherapy-treated patient developed cardiomyopathy. Four percent of patients required discontinuation and/or dose reduction of MEKINIST. Cardiomyopathy resolved in 10 of 14 patients.

    Across clinical trials of MEKINIST as a single agent, 11% of patients developed evidence of cardiomyopathy [decrease in LVEF below institutional lower limits of normal (LLN) with an absolute decrease in LVEF ≥ 10% below baseline] and 5% demonstrated a decrease in LVEF below institutional LLN with an absolute decrease in LVEF of ≥ 20% below baseline.

    In the COMBI-d study, evidence of cardiomyopathy (decrease in LVEF below the institutional LLN with an absolute decrease in LVEF ≥ 10% below baseline) occurred in 6% of patients receiving MEKINIST and dabrafenib and resulted in dose interruption (4.4%), dose reduction (2.4%), and permanent discontinuation (1.5%) of MEKINIST. Cardiomyopathy resolved in 10 of 12 patients receiving MEKINIST and dabrafenib.

    In the COMBI-AD study, cardiomyopathy, defined as a decrease in LVEF below the institutional lower limit of normal with an absolute decrease in LVEF > 10% below screening, occurred in 3% of patients receiving MEKINIST with dabrafenib 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 MEKINIST with dabrafenib.

    In Study BRF113298, cardiomyopathy, defined as a decrease in LVEF below the institutional lower limit of normal with an absolute decrease in LVEF > 10% below baseline, occurred in 9% of patients receiving MEKINIST with dabrafenib and resulted in dose interruption and permanent discontinuation of MEKINIST in 5% and 2.2% of patients, respectively. Cardiomyopathy resolved in 4 of 8 patients receiving MEKINIST and dabrafenib.

    Assess LVEF by echocardiogram or multigated acquisition (MUGA) scan before initiation of MEKINIST as a single agent or with dabrafenib, one month after initiation, and then at 2- to 3-month intervals while on treatment. Withhold MEKINIST for up to 4 weeks if absolute LVEF value decreases by 10% from pretreatment values and is less than the lower limit of normal. For symptomatic cardiomyopathy or persistent, asymptomatic LV dysfunction of > 20% from baseline that is below LLN that does not resolve within 4 weeks, permanently discontinue MEKINIST [see Dosage and Administration (2.7)].

    5.6       Ocular Toxicities

    Retinal Vein Occlusion (RVO)

    Across clinical trials with MEKINIST, the incidence of RVO was 0.2%. RVO may lead to macular edema, decreased visual function, neovascularization, and glaucoma.

    Urgently (within 24 hours) perform ophthalmological evaluation for patient-reported loss of vision or other visual disturbances. Permanently discontinue MEKINIST in patients with documented RVO [see Dosage and Administration (2.7)].

    Retinal Pigment Epithelial Detachment (RPED)

    Retinal pigment epithelial detachment (RPED) can occur with MEKINIST administration. Retinal detachments may be bilateral and multifocal, occurring in the central macular region of the retina or elsewhere in the retina. In melanoma and NSCLC trials, routine monitoring of patients to detect asymptomatic RPED was not conducted; therefore, the true incidence of this finding is unknown.

    Perform ophthalmological evaluation periodically and at any time a patient reports visual disturbances. Withhold MEKINIST if RPED is diagnosed. If resolution of the RPED is documented on repeat ophthalmological evaluation within 3 weeks, resume MEKINIST. Reduce the dose or discontinue MEKINIST if no improvement after 3 weeks [see Dosage and Administration (2.7)].

    5.7       Interstitial Lung Disease

    In clinical trials of single-agent MEKINIST, ILD or pneumonitis occurred in 2% of patients. In the METRIC study, 2.4% of patients treated with MEKINIST developed ILD or pneumonitis; all five patients required hospitalization. In the COMBI-d, COMBI-AD, and BRF113928 studies, 1.0%, < 1%, and 2.2% of patients receiving MEKINIST and dabrafenib developed pneumonitis, respectively.

    Withhold MEKINIST in patients presenting with new or progressive pulmonary symptoms and findings including cough, dyspnea, hypoxia, pleural effusion, or infiltrates, pending clinical investigations. Permanently discontinue MEKINIST for patients diagnosed with treatment-related ILD or pneumonitis [see Dosage and Administration (2.7)].

    5.8       Serious Febrile Reactions

    Serious febrile reactions and fever of any severity accompanied by hypotension, rigors or chills, dehydration, or renal failure, can occur when MEKINIST is administered with dabrafenib.

    Fever (serious and non-serious) occurred in 57% of patients with unresectable or metastatic melanoma receiving MEKINIST and dabrafenib. Approximately one-half of the patients who received MEKINIST and dabrafenib and experienced pyrexia had three or more discrete episodes.

    Across clinical trials of MEKINIST administered with dabrafenib in patients with unresectable or metastatic melanoma, serious febrile reactions or fever of any severity complicated by severe rigors/chills, hypotension, dehydration, renal failure, or syncope, occurred in 17% of patients receiving MEKINIST and dabrafenib. 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 MEKINIST for fever higher than 104ºF or for serious febrile reactions or fever accompanied 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 MEKINIST 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.

    5.9       Serious Skin Toxicity

    In the METRIC study, the overall incidence of any skin toxicity, the most common of which were rash, dermatitis acneiform rash, palmar-plantar erythrodysesthesia syndrome, and erythema, was 87% in patients receiving MEKINIST. Severe skin toxicity occurred in 12% of patients treated with MEKINIST. Skin toxicity requiring hospitalization occurred in 6% of patients treated with MEKINIST, most commonly for secondary infections of the skin requiring intravenous antibiotics or severe skin toxicity without secondary infection. Reductions in the dose of MEKINIST were required in 12% and permanent discontinuation of MEKINIST was required in 1% of patients with skin toxicity.

    In the COMBI-d study, the overall incidence of any skin toxicity was 55% for patients receiving MEKINIST and dabrafenib. No serious or severe cases of skin toxicity occurred in patients treated with MEKINIST and dabrafenib. Reductions in the dose of MEKINIST were required in 5% of patients receiving MEKINIST and dabrafenib and no patients required permanent discontinuation of MEKINIST for skin toxicity.

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

    Withhold MEKINIST for intolerable or severe skin toxicity. Resume MEKINIST at reduced doses in patients with improvement or recovery from skin toxicity within 3 weeks [see Dosage and Administration (2.7)].

    5.10       Hyperglycemia

    In the COMBI-d study, 27% of patients with a history of diabetes who received MEKINIST and dabrafenib required more intensive hypoglycemic therapy. Grade 3 and Grade 4 hyperglycemia based on laboratory values occurred in 5% and 0.5% of patients receiving MEKINIST and dabrafenib, respectively.

    Monitor serum glucose levels upon initiation and as clinically appropriate when MEKINIST is administered with dabrafenib in patients with pre-existing diabetes or hyperglycemia.

    5.11       Risks Associated with Combination Treatment

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

    5.12       Embryo-Fetal Toxicity

    Based on findings from animal studies and its mechanism of action, MEKINIST can cause fetal harm when administered to a pregnant woman. Trametinib was embryotoxic and abortifacient in rabbits at doses greater than or equal to those resulting in exposures approximately 0.3 times the human exposure at the recommended clinical dose. If MEKINIST is used during pregnancy, or if the patient becomes pregnant while taking MEKINIST, advise the patient of the potential risk to a fetus [see Use in Specific Populations (8.1)].

    Advise female patients of reproductive potential to use effective contraception during treatment with MEKINIST and for 4 months after treatment. Advise patients to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, while taking MEKINIST [see Use in Specific Populations (8.1)].

    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 MEKINIST administered as a single agent in 329 patients with various solid tumors and exposure to MEKINIST administered with dabrafenib in 559 patients with unresectable or metastatic melanoma and 93 patients with NSCLC. MEKINIST as a single agent was evaluated in 329 patients including 107 (33%) exposed for greater than or equal to 6 months and 30 (9%) exposed for greater than or equal to one year. MEKINIST as a single agent was studied in open-label, single-arm trials (N = 118) and in an open-label, randomized, active-controlled trial (N = 211; the METRIC study). The median age was 54 years, 60% were male, > 99% were White, and all patients had unresectable or metastatic melanoma. All patients received 2 mg once-daily doses of MEKINIST.

    Unresectable or Metastatic BRAF V600E or V600K Mutation Positive Melanoma

    MEKINIST Administered as a Single Agent

    Table 3 presents adverse reactions identified from analyses of the METRIC study, a randomized, open-label trial of patients with BRAF V600E or V600K mutation-positive unresectable or metastatic melanoma receiving MEKINIST (N = 211) 2 mg orally once daily or chemotherapy (N = 99) (either dacarbazine 1,000 mg/m2 every 3 weeks or paclitaxel 175 mg/m2 every 3 weeks) [see Clinical Studies (14.1)]. Patients with abnormal LVEF, history of acute coronary syndrome within 6 months, or current evidence of Class II or greater congestive heart failure (New York Heart Association) were excluded. The median duration of treatment with MEKINIST was 4.3 months. In this study, 9% of patients receiving MEKINIST experienced adverse reactions resulting in permanent discontinuation of trial medication. The most common adverse reactions resulting in permanent discontinuation of MEKINIST were decreased left ventricular ejection fraction (LVEF), pneumonitis, renal failure, diarrhea, and rash. Adverse reactions led to dose reductions in 27% of patients treated with MEKINIST. Rash and decreased LVEF were the most common reasons cited for dose reductions of MEKINIST.

    MEKINIST Administered with Dabrafenib

    The safety of MEKINIST, administered with dabrafenib, was evaluated in 559 patients with previously untreated, unresectable or metastatic, BRAF V600 mutation-positive melanoma who received MEKINIST 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 both trials, patients received MEKINIST 2 mg orally once daily and dabrafenib 150 mg orally twice daily until disease progression or unacceptable toxicity. The trials 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), history of RVO or RPED, QTcB interval ≥ 480 msec, uncontrolled hypertension, uncontrolled arrhythmias, active brain metastases, or known history of G6PD deficiency.

    Among these 559 patients, 197 (35%) were exposed to MEKINIST for > 6 months to 12 months while 185 (33%) were exposed to MEKINIST for > 1 year. The median age was 55 years (range: 18 to 91), 57% were male, and 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 LDH at baseline, and 0.5% had a history of brain metastases.

    The most commonly occurring adverse reactions (≥ 20%) for MEKINIST in patients receiving MEKINIST plus dabrafenib were: pyrexia, nausea, rash, chills, diarrhea, vomiting, hypertension, and peripheral edema.

    The demographics and baseline tumor characteristics of patients enrolled in the COMBI-d study are summarized in Clinical Studies [see Clinical Studies (14.1)]. Patients receiving MEKINIST plus dabrafenib had a median duration of exposure of 11 months (range: 3 days to 30 months) to MEKINIST. Among the 209 patients receiving MEKINIST plus dabrafenib, 26% were exposed to MEKINIST for > 6 months to 12 months while 46% were exposed to MEKINIST for > 1 year.

    In the COMBI-d study, adverse reactions leading to discontinuation of MEKINIST occurred in 11% of patients receiving MEKINIST plus dabrafenib; the most common were pyrexia (1.4%) and decreased ejection fraction (1.4%). Adverse reactions leading to dose reductions of MEKINIST occurred in 18% of patients receiving MEKINIST plus dabrafenib; the most common were pyrexia (2.9%), neutropenia (1.9%), decreased ejection fraction (1.9%), and rash (1.9%). Adverse reactions leading to dose interruptions of MEKINIST occurred in 46% of patients receiving MEKINIST plus dabrafenib; the most common were pyrexia (18%), chills (7%), vomiting (6%) and decreased ejection fraction (4.8%).

    Adjuvant Treatment of BRAF V600E or V600K Mutation-Positive Melanoma

    The safety of MEKINIST when administered with dabrafenib 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 (14.2)]. Patients received MEKINIST 2 mg orally once daily and dabrafenib 150 mg orally twice 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 MEKINIST in combination with dabrafenib 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 1. Patients receiving MEKINIST in combination with dabrafenib had a median duration of exposure of 11 months (range: 0 to 12) to MEKINIST. Among the 435 patients receiving MEKINIST in combination with dabrafenib, 72% were exposed to MEKINIST for > 6 months.

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

    Adverse reactions resulting in discontinuation and dose interruptions of MEKINIST occurred in 24% and 54% of patients, respectively; the most common for each were pyrexia and chills. Adverse reactions leading to dose reductions of MEKINIST occurred in 23% of patients; the most common were pyrexia and ejection fraction decrease.

    Metastatic, BRAF V600E Mutation-Positive NSCLC

    The safety of MEKINIST when administered with dabrafenib 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 MEKINIST 2 mg orally once daily and dabrafenib 150 mg orally twice 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 (14.3)].

    Among these 93 patients, 53 (57%) were exposed to MEKINIST and dabrafenib for > 6 months and 27 (29%) were exposed to MEKINIST and dabrafenib 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 commonly occurring 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 MEKINIST occurred in 19% of patients; the most common were pyrexia (2.2%), ejection fraction decreased (2.2%), and respiratory distress (2.2%). Adverse reactions leading to dose reductions of MEKINIST occurred in 30% of patients receiving MEKINIST plus dabrafenib; the most common were pyrexia (5%), nausea (4.3%), vomiting (4.3%), diarrhea (3.2%), and neutropenia (3.2%). Adverse reactions leading to dose interruptions of MEKINIST occurred in 57% of patients receiving MEKINIST plus dabrafenib; the most common were pyrexia (16%), vomiting (10%), neutropenia (8%), nausea (5%), and ejection fraction decreased (5%).

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

    The safety of MEKINIST when administered with dabrafenib 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 MEKINIST or dabrafenib. Patients received MEKINIST 2 mg orally once daily and dabrafenib 150 mg orally twice daily until disease progression or unacceptable toxicity.

    Among these 100 patients, 46 (46%) were exposed to MEKINIST and dabrafenib for > 6 months and 23 (23%) were exposed to MEKINIST and dabrafenib 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.

  • 8       USE IN SPECIFIC POPULATIONS

    8.1       Pregnancy

    Risk Summary

    Based on its mechanism of action and findings from animal reproduction studies, MEKINIST can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There is insufficient data in pregnant women exposed to MEKINIST to assess the risks. Trametinib was embryotoxic and abortifacient in rabbits at doses greater than or equal to those resulting in exposures approximately 0.3 times the human exposure at the recommended clinical dose (see Data). If MEKINIST is used during pregnancy, or if the patient becomes pregnant while taking MEKINIST, advise the patient of the potential risk to the 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 reproductive toxicity studies, administration of trametinib to rats during the period of organogenesis resulted in decreased fetal weights at doses greater than or equal to 0.031 mg/kg/day (approximately 0.3 times the human exposure based on AUC at the recommended dose). In rats, at a dose resulting in exposures 1.8-fold higher than the human exposure at the recommended dose, there was maternal toxicity and an increase in post-implantation loss.

    In pregnant rabbits, administration of trametinib during the period of organogenesis resulted in decreased fetal body weight and increased incidence of variations in ossification at doses greater than or equal to 0.039 mg/kg/day (approximately 0.08 times the human exposure at the recommended dose based on AUC). In rabbits administered trametinib at 0.15 mg/kg/day (approximately 0.3 times the human exposure at the recommended dose based on AUC) there was an increase in post-implantation loss, including total loss of pregnancy, compared with control animals.

    8.2       Lactation

    Risk Summary

    There are no data on the presence of trametinib in human milk, or the effects of trametinib on the breastfed infant, or on milk production. Because of the potential for serious adverse reactions in breastfed infants from MEKINIST, advise women not to breastfeed during treatment with MEKINIST and for 4 months following the last dose.

    8.3       Females and Males of Reproductive Potential

    Contraception

    Based on its mechanism of action and findings from animal reproduction studies, MEKINIST 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 MEKINIST and for 4 months after the last dose. Advise patients to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, while taking MEKINIST.

    Infertility

    Females: Advise female patients of reproductive potential that MEKINIST may impair fertility. Increased follicular cysts and decreased corpora lutea were observed in female rats at dose exposures equivalent to 0.3 times the human exposure at the recommended dose [see Nonclinical Toxicology (13.1)].

    8.4       Pediatric Use

    The safety and effectiveness of MEKINIST as a single agent or in combination with dabrafenib have not been established in pediatric patients.

    Juvenile Animal Data

    In a repeat-dose toxicity study in juvenile rats, decreased bone length and corneal dystrophy were observed at doses resulting in exposures as low as 0.3 times the human exposure at the recommended adult dose based on AUC. Additionally, a delay in sexual maturation was noted at doses resulting in exposures as low as 1.6 times the human exposure at the recommended adult dose based on AUC.

    8.5       Geriatric Use

    Clinical trials of MEKINIST as a single agent did not include sufficient numbers of subjects aged 65 and older to determine whether they respond differently from younger subjects.

    Of the 994 patients with melanoma randomized to receive MEKINIST plus dabrafenib in the COMBI-d, COMBI-v, and COMBI-AD studies, 21% were aged 65 years and older and 5% were aged 75 years and older. No overall differences in the effectiveness of MEKINIST plus dabrafenib were observed in elderly patients as compared to younger patients across the melanoma studies. The incidences of peripheral edema (26% vs. 12%) and anorexia (21% vs. 9%) increased in elderly patients as compared to younger patients in the metastatic melanoma studies.

    Clinical studies of MEKINIST in NSCLC did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

    8.6       Hepatic Impairment

    No dose adjustment is recommended in patients with mild hepatic impairment [see Clinical Pharmacology (12.3)]. The appropriate dose of MEKINIST has not been established in patients with moderate or severe hepatic impairment.

    8.7       Renal Impairment

    No dose adjustment is recommended in patients with mild or moderate renal impairment [see Clinical Pharmacology (12.3)]. The appropriate dose of MEKINIST has not been established in patients with severe renal impairment.

  • 10       OVERDOSAGE

    The highest doses of MEKINIST evaluated in clinical trials were 4 mg orally once daily and 10 mg administered orally once daily on 2 consecutive days followed by 3 mg once daily. In seven patients treated on one of these two schedules, there were two cases of retinal pigment epithelial detachments for an incidence of 28%.

    Since trametinib is highly bound to plasma proteins, hemodialysis is likely to be ineffective in the treatment of overdose with MEKINIST.

  • 12       CLINICAL PHARMACOLOGY

    12.1       Mechanism of Action

    Trametinib is a reversible inhibitor of mitogen-activated extracellular signal-regulated kinase 1 (MEK1) and MEK2 activation and of MEK1 and MEK2 kinase activity. MEK proteins are upstream regulators of the extracellular signal-related kinase (ERK) pathway, which promotes cellular proliferation. BRAF V600E mutations result in constitutive activation of the BRAF pathway which includes MEK1 and MEK2. Trametinib inhibits cell growth of various BRAF V600 mutation-positive tumors in vitro and in vivo.

    Trametinib and dabrafenib target two different kinases in the RAS/RAF/MEK/ERK pathway. Use of trametinib and dabrafenib 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

    Administration of 1 mg and 2 mg MEKINIST to patients with BRAF V600 mutation-positive melanoma resulted in dose-dependent changes in tumor biomarkers including inhibition of phosphorylated ERK, inhibition of Ki67 (a marker of cell proliferation), and increases in p27 (a marker of apoptosis).

    Cardiac Electrophysiology

    The heart rate-corrected QT (QTc) prolongation potential of trametinib was assessed in a dedicated study in 32 patients who received placebo on day 1 and MEKINIST 2 mg once daily on days 2-14 followed by MEKINIST 3 mg on day 15. No clinically relevant QTc prolongation was detected in the study.

    In clinical trials in patients receiving MEKINIST in combination with dabrafenib, QTc prolongation > 500 ms occurred in 0.8% of patients, and QTc increased by > 60 ms from baseline in 3.8% of patients.

    12.3       Pharmacokinetics

    The pharmacokinetics of trametinib were characterized following single- and repeat-oral administration in patients with solid tumors and BRAF V600 mutation-positive metastatic melanoma.

    Absorption

    After oral administration of MEKINIST, the median time to achieve peak plasma concentrations (Tmax) is 1.5 hours post-dose. The mean absolute bioavailability of a single oral dose of MEKINIST 2 mg is 72%. The increase in Cmax was dose proportional after a single dose of 0.125 mg (0.0625 times the approved recommended dosage) to 10 mg (5 times the approved recommended dosage) while the increase in AUC was greater than dose proportional. After repeat doses of 0.125 mg to 4 mg daily, both Cmax and AUC increase proportionally with dose. Inter-subject variability in AUC and Cmax at steady state is 22% and 28%, respectively.

    Effect of Food

    Administration of a single dose of MEKINIST with a high-fat, high-calorie meal (approximately 1000 calories) decreased trametinib AUC by 24%, Cmax by 70%, and delayed Tmax by approximately 4 hours as compared with fasted conditions.

    Distribution

    Trametinib is 97.4% bound to human plasma proteins. The apparent volume of distribution (Vc/F) is 214 L.

    Elimination

    The estimated elimination half-life of trametinib based on the population PK model is 3.9 to 4.8 days. The apparent clearance is 4.9 L/h.

    Metabolism

    Trametinib is metabolized predominantly via deacetylation alone or with mono-oxygenation or in combination with glucuronidation biotransformation pathways in vitro. Deacetylation is mediated by carboxylesterases (i.e., carboxylesterase 1b/c and 2) and may also be mediated by other hydrolytic enzymes.

    Following a single dose of [14C]-trametinib, approximately 50% of circulating radioactivity is represented as the parent compound. However, based on metabolite profiling after repeat dosing of trametinib, ≥ 75% of drug-related material in plasma is the parent compound.

    Excretion

    Following oral administration of [14C]-trametinib, greater than 80% of excreted radioactivity was recovered in the feces while less than 20% of excreted radioactivity was recovered in the urine with less than 0.1% of the excreted dose as parent.

    Specific Populations

    Age, Body Weight, and Sex: Age, sex, and body weight do not have a clinically important effect on the exposure of trametinib. There are insufficient data to evaluate potential differences in the exposure of trametinib by race or ethnicity.

    Hepatic Impairment: Based on a population pharmacokinetic analysis in 64 patients with mild hepatic impairment (total bilirubin ≤ ULN and AST > ULN or total bilirubin greater than 1 to 1.5 x ULN and any AST), mild hepatic impairment has no clinically important effect on the systemic exposure of trametinib. The pharmacokinetics of trametinib have not been studied in patients with moderate or severe hepatic impairment.

    Renal Impairment: Based on a population pharmacokinetic analysis in 223 patients with mild renal impairment (GFR 60 to 89 mL/min/1.73 m2) and 35 patients with moderate renal impairment (GFR 30 to 59 mL/min/1.73 m2), mild and moderate renal impairment have no clinically important effects on the systemic exposure of trametinib. The pharmacokinetics of trametinib have not been studied in patients with severe renal impairment.

    Pediatrics: No trials have been conducted to evaluate the pharmacokinetics of trametinib in pediatric patients.

    Drug Interactions

    Effect of Trametinib on CYP Substrates: Based on in vitro studies, trametinib is an inhibitor of CYP2C8, but is not an inhibitor of CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2C19, CYP2D6, or CYP3A4 at a clinically relevant systemic concentration of 0.04 µM. Trametinib is an inducer of CYP3A in vitro. Based on cross-study comparisons, oral administration of MEKINIST 2 mg once daily with a sensitive CYP3A4 substrate had no clinically important effect on the AUC and Cmax of the sensitive CYP3A4 substrate.

    Effect of Transporters on Trametinib: Trametinib is a substrate of P-glycoprotein (P-gp) and bile salt extrusion pump (BSEP). Inhibition of P-gp is unlikely to result in a clinically important increase in trametinib concentrations as trametinib exhibits high passive permeability and bioavailability. Trametinib is not a substrate of breast cancer resistance protein (BCRP), organic anion transporting polypeptide (OATP1B1, OATP1B3, OATP2B1), organic cation transporter 1 (OCT1), multidrug resistance protein 2 (MRP2), or multidrug and toxin extrusion 1 (MATE1) in vitro.

    Effect of Trametinib on Transporters: Based on in vitro studies, trametinib is not an inhibitor of P-gp, BCRP, OATP1B1, OATP1B3, organic anion transporter (OAT1, OAT3), OCT2, BSEP, MRP2, or MATE1 at a clinically relevant systemic concentration of 0.04 µM.

    Effect of Dabrafenib on Trametinib: Coadministration of trametinib 2 mg daily with dabrafenib 150 mg twice daily resulted in no change in AUC of trametinib as compared with administration of trametinib.

    Carcinogenicity studies with trametinib have not been conducted. Trametinib was not genotoxic in studies evaluating reverse mutations in bacteria, chromosomal aberrations in mammalian cells, and micronuclei in the bone marrow of rats.

    Trametinib may impair fertility in humans. In female rats given trametinib for up to 13 weeks, increased follicular cysts and decreased corpora lutea were observed at doses ≥ 0.016 mg/kg/day (approximately 0.3 times the human exposure at the recommended dose based on AUC). In rat and dog toxicity studies up to 13 weeks in duration, there were no treatment effects observed on male reproductive tissues [see Use in Specific Populations (8.3)].

    14.1       BRAF V600E or V600K Mutation-Positive Unresectable or Metastatic Melanoma 

    MEKINIST as a Single Agent  

    The safety and efficacy of MEKINIST were evaluated in an international, multicenter, randomized (2:1), open-label, active-controlled trial (the METRIC study; NCT01245062) in 322 patients with BRAF V600E or V600K mutation-positive, unresectable or metastatic melanoma.

    In the METRIC study, patients were not permitted to have more than one prior chemotherapy regimen for advanced or metastatic disease; prior treatment with a BRAF inhibitor or MEK inhibitor was not permitted. The primary efficacy outcome measure was progression-free survival (PFS). Patients were randomized to receive MEKINIST 2 mg orally once daily (N = 214) or chemotherapy (N = 108) consisting of either dacarbazine 1,000 mg/m2 intravenously every 3 weeks or paclitaxel 175 mg/m2 intravenously every 3 weeks. Treatment continued until disease progression or unacceptable toxicity. Randomization was stratified according to prior use of chemotherapy for advanced or metastatic disease (yes versus no) and lactate dehydrogenase level (normal versus greater than upper limit of normal). Tumor tissue was evaluated for BRAF mutations at a central testing site using a clinical trial assay. Tumor samples from 289 patients (196 patients treated with MEKINIST and 93 chemotherapy-treated patients) were also tested retrospectively using an FDA-approved companion diagnostic test, THxID™-BRAF assay.

    The median age for randomized patients was 54 years, 54% were male, greater than 99% were White, and all patients had baseline ECOG performance status of 0 or 1. Most patients had metastatic disease (94%), were Stage M1c (64%), had elevated LDH (36%), had no history of brain metastasis (97%), and received no prior chemotherapy for advanced or metastatic disease (66%). The distribution of BRAF V600 mutations was BRAF V600E (87%), V600K (12%), or both (less than 1%). The median durations of follow-up prior to initiation of alternative treatment were 4.9 months for patients treated with MEKINIST and 3.1 months for patients treated with chemotherapy. Fifty-one (47%) patients crossed over from the chemotherapy arm at the time of disease progression to receive MEKINIST.

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

    MEKINIST with Dabrafenib

    The safety and efficacy of MEKINIST administered with dabrafenib were evaluated in an international, randomized, double-blind, active-controlled trial (the COMBI-d study; NCT01584648). The COMBI-d study compared dabrafenib plus MEKINIST to dabrafenib plus placebo as first-line treatment 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 MEKINIST 2 mg once daily plus dabrafenib 150 mg twice daily or dabrafenib 150 mg twice daily plus matching placebo. Randomization was stratified by lactate dehydrogenase (LDH) level (greater than the upper limit of normal (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).

    In the COMBI-d study, 423 patients were randomized to MEKINIST plus dabrafenib (n = 211) or dabrafenib 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 with the FDA-approved companion diagnostic test; 85% had BRAF V600E mutation-positive melanoma and 15% had BRAF V600K mutation-positive melanoma.

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

    COMBI-AD (NCT01682083) 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 MEKINIST 2 mg once daily in combination with dabrafenib 150 mg twice 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 the MEKINIST in combination with dabrafenib and 432 to placebo. Median age was 51 years (range: 18 to 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 MEKINIST in combination with dabrafenib arm compared to those randomized to placebo. Efficacy results are presented in Table 13 and Figure 3.

    14.3       BRAF V600E Mutation-Positive Metastatic Non-Small Cell Lung Cancer (NSCLC) 

    In Study BRF113928 (NCT01336634), the safety and efficacy of dabrafenib alone or administered with MEKINIST were evaluated in a multicenter, three-cohort, non-randomized, activity-estimating, open-label trial. 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 with demonstrated disease progression but no more than three prior systemic regimens. Patients in Cohort C could not have received prior systemic therapy for metastatic disease. Patients in Cohort A received dabrafenib 150 mg twice daily. Patients in Cohorts B and C received MEKINIST 2 mg once daily and dabrafenib 150 mg twice daily. The major efficacy outcome was overall response rate (ORR) per RECIST v1.1 as assessed by independent review committee (IRC) and duration of response.

    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 population were: a median age of 66 years; 48% male; 81% White, 14% Asian, 3% Black and 2% Hispanic; 60% former smokers, 32% never smokers, and 8% current smokers; 27% had ECOG performance status (PS) of 0, 63% had ECOG PS of 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, 58% of the 135 previously treated patients had only one line of prior systemic therapy for metastatic disease; 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.

    14.4       BRAF V600E Mutation-Positive Locally Advanced or Metastatic Anaplastic Thyroid Cancer (ATC)

    The safety and efficacy of MEKINIST administered with dabrafenib was evaluated in Study BRF117019 (NCT02034110), an activity-estimating, nine-cohort, multi-center, non-randomized, open-label trial in patients with rare cancers with the BRAF V600E mutation, including locally advanced, unresectable, or metastatic anaplastic thyroid cancer (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 MEKINIST 2 mg once daily and dabrafenib 150 mg twice daily. The major efficacy outcome measure was overall response rate (ORR) per RECIST v1.1 as assessed by independent review committee (IRC) and duration of response (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.

    14.5       Lack of Clinical Activity in Metastatic Melanoma Following BRAF-Inhibitor Therapy

    The clinical activity of MEKINIST as a single agent was evaluated in a single-arm, multicenter, international trial in 40 patients with BRAF V600E or V600K mutation-positive, unresectable or metastatic melanoma who had received prior treatment with a BRAF inhibitor. All patients received MEKINIST at a dose of 2 mg orally once daily until disease progression or unacceptable toxicity.

    The median age was 58 years, 63% were male, all were White, 98% had baseline ECOG PS of 0 or 1, and the distribution of BRAF V600 mutations was V600E (83%), V600K (10%), and the remaining patients had multiple V600 mutations (5%), or unknown mutational status (2%). No patient achieved a confirmed partial or complete response as determined by the clinical investigators.

    What is the most important information I should know about MEKINIST?
    MEKINIST may cause serious side effects, including:
    Risk of new skin cancers. MEKINIST, when used with dabrafenib, may cause skin cancers,
    called cutaneous squamous cell carcinoma, keratoacanthoma, basal cell carcinoma, or melanoma.
    Talk to 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 MEKINIST and dabrafenib, every 2 months during treatment with MEKINIST and dabrafenib and for up to 6 months after you stop taking MEKINIST and dabrafenib 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 MEKINIST with dabrafenib.
    See "What are the possible side effects of MEKINIST?" for more information about side effects.
    What is MEKINIST?
    MEKINIST is a prescription medicine used:
