  • 3 DOSAGE FORMS AND STRENGTHS

    25 mg capsules: pale orange oblong soft capsule with red ink imprint ‘PKC NVR’.

  • 4 CONTRAINDICATIONS

    RYDAPT is contraindicated in patients with hypersensitivity to midostaurin or to any of the excipients [see Description (11)]. Hypersensitivity reactions have included anaphylactic shock, dyspnea, flushing, chest pain, and angioedema (e.g., swelling of the airways or tongue, with or without respiratory impairment) [see Adverse Reactions (6.1)].

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Embryo-Fetal Toxicity

    Based on its mechanism of action and findings from animal reproduction studies, RYDAPT may cause fetal harm when administered to pregnant women. In animal studies, midostaurin caused embryo-fetal toxicities, including late embryo-fetal death and reduced fetal birth weight, with delays in fetal growth at doses lower than the recommended human dose. Advise pregnant women of the potential risk to the fetus. Verify the pregnancy status of females of reproductive potential within 7 days prior to initiating RYDAPT therapy. Advise females of reproductive potential to use effective contraception during treatment with RYDAPT and for at least 4 months after the last dose. Advise males with female partners to use effective contraception during treatment with RYDAPT and for 4 months after the last dose [see Use in Specific Populations (8.1, 8.3), Clinical Pharmacology (12.1)].

    5.2 Pulmonary Toxicity

    Cases of interstitial lung disease and pneumonitis, some fatal, have occurred in patients treated with RYDAPT as monotherapy or with chemotherapy. Monitor patients for pulmonary symptoms. Discontinue RYDAPT in patients who experience signs or symptoms of interstitial lung disease or pneumonitis without an infectious etiology.

  • 6 ADVERSE REACTIONS

    The following serious adverse reactions are described elsewhere in the labeling:

    • Pulmonary Toxicity [see Warnings and Precautions (5.2)]

    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.

    Acute Myeloid Leukemia

    The safety evaluation of RYDAPT (50 mg twice daily with food) in patients with newly diagnosed FLT3 mutated AML is based on a randomized, double-blind, trial of RYDAPT (n = 345) or placebo (n = 335) with chemotherapy [see Clinical Studies (14.1)]. The overall median duration of exposure was 42 days (range 2 to 576 days) for patients in the RYDAPT plus chemotherapy arm versus 34 days (range 1 to 465 days) for patients in the placebo plus chemotherapy arm. On the RYDAPT plus chemotherapy arm, 35% of patients completed induction and consolidation therapy, compared to 25% of patients on the placebo plus chemotherapy arm.

    The most frequent (incidence greater than or equal to 20%) adverse drug reactions (ADRs) in the RYDAPT plus chemotherapy arm were febrile neutropenia, nausea, mucositis, vomiting, headache, petechiae, musculoskeletal pain, epistaxis, device-related infection, hyperglycemia, and upper respiratory tract infections. The most frequent Grade 3/4 adverse reactions (incidence ≥ 10%) were febrile neutropenia, device-related infection and mucositis.

    The most frequent serious adverse reaction (≥ 10%) in patients in the RYDAPT plus chemotherapy arm was febrile neutropenia (16%), which occurred at a similar rate in the placebo arm (16%).

    Discontinuation due to any adverse reaction occurred in 9% of patients in the RYDAPT arm versus 6% in the placebo arm. The most frequent (> 1%) Grade 3/4 adverse reactions leading to discontinuation in the RYDAPT arm was renal insufficiency (1%).

    Excluding deaths due to disease progression, no fatal adverse reactions occurred in the study. Overall, the most frequent non-treatment related cause of death in the RYDAPT plus chemotherapy arm was sepsis (2%) and occurred at a similar rate in the placebo arm (2%).

    Table 2 presents the frequency category of adverse reactions reported in the randomized trial in patients with newly diagnosed FLT3 mutated AML. Adverse reactions are listed according to body system. Within each body system, the adverse reactions are ranked by frequency, with the most frequent reactions first. Table 3 presents the key laboratory abnormalities from the same randomized trial in patients with newly diagnosed FLT3 mutated AML.

    In Study 1, 205 patients (120 in RYDAPT arm and 85 in placebo arm) who remained in remission following completion of consolidation continued to receive either single agent RYDAPT or placebo for a median of 11 months (range 0.5 to 17 months) with 69 in the RYDAPT arm and 51 in the placebo completing 12 treatment cycles. Common adverse reactions (greater than or equal to 5% difference between the RYDAPT and placebo arms) reported for these patients included nausea (47% vs. 18%), hyperglycemia (20% vs. 13%) and vomiting (19% vs. 5%).

    Systemic Mastocytosis

    Two single-arm, open-label multicenter trials (Study 2 and Study 3) evaluated the safety of RYDAPT (100 mg twice daily with food) as a single agent in 142 adult patients total with ASM, SM-AHN, or MCL. The median age was 63 (range 24 to 82), 63% had an ECOG performance status of 0 or 1, and 75% had no hepatic impairment (bilirubin and AST ≤ ULN) at baseline. The median duration of exposure to RYDAPT was 11.4 months (range 0 to 81 months), with 34% treated for ≥ 24 months.

    The most frequent adverse reactions (≥ 20%), excluding laboratory terms, were nausea, vomiting, diarrhea, edema, musculoskeletal pain, abdominal pain, fatigue, upper respiratory tract infection, constipation, pyrexia, headache, and dyspnea (Table 4). Grade ≥ 3 adverse reactions reported in ≥ 5%, excluding laboratory terms, were fatigue, sepsis, gastrointestinal hemorrhage, pneumonia, diarrhea, febrile neutropenia, edema, dyspnea, nausea, vomiting, abdominal pain, and renal insufficiency (Table 4).

    Adverse reactions led to dose modifications (interruption or reduction) in 56% of patients. Among these, the most frequent adverse reactions (> 5%) were gastrointestinal symptoms, QT prolongation, neutropenia, pyrexia, thrombocytopenia, gastrointestinal hemorrhage, lipase increase, and fatigue. The median time to first dose modification for toxicity was 1.6 months, with 75% of dose modifications first occurring within 5 months of starting treatment.

    Treatment discontinuation due to adverse reactions occurred in 21% of patients. The most frequent adverse reactions causing treatment discontinuation included infection, nausea or vomiting, QT prolongation, and gastrointestinal hemorrhage.

    Serious adverse reactions were reported in 68% of patients, most commonly (≥ 20%) due to infections and gastrointestinal disorders.

    On-treatment deaths unrelated to the underlying malignancy occurred in 16 patients (11%), most commonly from infection (sepsis or pneumonia), followed by cardiac events. Of the on-treatment deaths from disease progression, 4 were also attributable to infection.

    Table 4 summarizes the adverse reactions reported in ≥ 10% of the patients with advanced SM.

  • 7 DRUG INTERACTIONS

    7.1 Effect of Strong Cytochrome P450 (CYP) 3A Inhibitors and Inducers

    Table 6 lists the potential effects of the coadministration of strong CYP3A modulators on RYDAPT.

    Table 6: Drug Interactions With RYDAPT That Affect Midostaurin
      Strong CYP3A Inhibitors
      Clinical Impact
    • Coadministration of RYDAPT with strong CYP3A inhibitors may increase midostaurin concentrations. The increase in midostaurin concentrations may be pronounced if strong CYP3A inhibitors are administered during the first week of RYDAPT administration [see Clinical Pharmacology (12.3)].
    • Increased midostaurin concentrations may increase the risk of toxicity.
      Prevention or Management
    • Consider alternative therapies that do not strongly inhibit CYP3A activity.
    • Alternatively, with coadministration of RYDAPT and strong CYP3A inhibitors, monitor patients for increased risk of adverse reactions, especially during the first week of consecutive RYDAPT administration in advanced SM population, and during first week of RYDAPT administration in each cycle of chemotherapy in AML population.
      ExamplesBoceprevir, clarithromycin, cobicistat, conivaptan, danoprevir and ritonavir, diltiazem, elvitegravir and ritonavir, grapefruit juicea, idelalisib, indinavir and ritonavir, itraconazole, ketoconazole, lopinavir and ritonavir, nefazodone, nelfinavir, paritaprevir and ritonavir and (ombitasvir and/or dasabuvir), posaconazole, ritonavir, saquinavir and ritonavir, tipranavir and ritonavir, troleandomycin, voriconazole
      Strong CYP3A Inducers
      Clinical Impact
    • Coadministration of RYDAPT with strong CYP3A inducers may decrease midostaurin concentrations [see Clinical Pharmacology (12.3)].
    • Decreased midostaurin concentrations may reduce efficacy.
      Prevention or ManagementAvoid coadministration of RYDAPT with strong CYP3A4 inducers.
      ExamplesCarbamazepine, enzalutamide, mitotane, phenytoin, rifampin, St. John’s wortb

    aThe effect of grapefruit juice varies widely among brands and is concentration-, dose-, and preparation-dependent. Studies have shown that it can be classified as a “strong CYP3A inhibitor” when a certain preparation was used (e.g., high dose, double strength) or as a “moderate CYP3A inhibitor” when another preparation was used (e.g., low dose, single strength).

    bThe induction potency of St. John’s wort may vary widely based on preparation.

    Risk Summary

    Based on mechanism of action and findings in animal reproduction studies, RYDAPT may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on RYDAPT use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. In animal reproduction studies, oral administration of midostaurin to pregnant rats and rabbits during organogenesis caused embryo-fetal toxicities, including late embryo-fetal death and reduced fetal birth weight, with delays in fetal growth at doses lower than the recommended human dose (see Data). Advise pregnant women of the potential risk to a fetus.

    The background risk of major birth defects and miscarriage for the indicated population are unknown. Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

    Data

    Animal Data

    When midostaurin was administered to female rats prior to mating and through the first week of pregnancy at a dose of 60 mg/kg/day [approximately 0.1 times the human exposure at the recommended dose based on area under the curve (AUC)], there were increases in pre- and post-implantation loss, including total litter loss, resulting in a reduction in the number of live embryos.

    During organogenesis, midostaurin administered at oral doses greater than or equal to 3 mg/kg/day (approximately 0.004 times the human exposure at the recommended dose by AUC) to pregnant female rats caused late embryo-fetal death. Dilated lateral brain ventricles were observed in offspring of rats given doses greater than or equal to 3 mg/kg/day. Extra rib and reduced fetal birth weight with effects on fetal growth (severe renal pelvic cavitation and widened anterior fontanelle) were observed in the absence of maternal toxicity at the highest dose of 30 mg/kg/day (approximately 0.05 times the human exposure at the recommended dose by AUC). Midostaurin administered orally to pregnant rabbits during organogenesis led to maternal toxicity with spontaneous abortions and some delay in fetal growth (reduced fetal birth weight) at doses greater than or equal to 10 mg/kg/day (approximately 0.01 times the human exposure at the recommended dose by AUC).

    In an oral pre- and postnatal development study in the rat, adverse effects upon maternal performance included dams with signs of dystocia and a lower live litter size at 30 mg/kg/day (approximately 0.05 times the human exposure at the recommended dose by AUC). For the F1 offspring, lower body weights, accelerated complete eye opening and delayed auricular startle ontogeny were noted at 30 mg/kg/day.

    8.2 Lactation

    Risk Summary

    There are no data on the presence of midostaurin or its active metabolites in human milk, the effect on the breastfed infant, or the effect on milk production. Orally administered midostaurin and its active metabolites pass into the milk of lactating rats within 1 hour of a 30 mg/kg/day dose, with approximately 5 times more in the milk of lactating rats compared to plasma. Because of the potential for serious adverse reactions in breastfed infants from RYDAPT advise women not to breastfeed during treatment with RYDAPT and for at least 4 months after the last dose.

    8.3 Females and Males of Reproductive Potential

    Pregnancy Testing

    Pregnancy testing is recommended for females of reproductive potential within seven days prior to initiating RYDAPT.

    Contraception

    Females

    RYDAPT may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment with RYDAPT and for 4 months after the last dose.

    Males

    Males with female sexual partners of reproductive potential should use effective contraception during RYDAPT treatment and for at least 4 months after stopping treatment with RYDAPT [see Nonclinical Toxicology (13.1)].

    Infertility

    Based on findings in animals, RYDAPT may impair fertility in females and males of reproductive potential. It is not known whether these effects on fertility are reversible [see Nonclinical Toxicology (13.1)].

    8.4 Pediatric Use

    Safety and effectiveness of RYDAPT have not been established in pediatric patients.

    8.5 Geriatric Use

    Of the 142 patients with advanced SM in clinical studies of RYDAPT, 64 (45%) were aged 65 and over, and 16 (11%) were aged 75 years and over. No overall differences in safety or response rate were observed between the subjects aged 65 and over compared with younger subjects. Greater sensitivity of older individuals cannot be ruled out.

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

    In general, administration for elderly patients should be cautious, based on patient’s eligibility for concomitant chemotherapy and reflecting the greater frequency of concomitant disease or other drug therapy.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Midostaurin is a small molecule that inhibits multiple receptor tyrosine kinases. In vitro biochemical or cellular assays have shown that midostaurin or its major human active metabolites CGP62221 and CGP52421 inhibit the activity of wild type FLT3, FLT3 mutant kinases (ITD and TKD), KIT (wild type and D816V mutant), PDGFRα/β, VEGFR2, as well as members of the serine/threonine kinase PKC (protein kinase C) family.

    Midostaurin demonstrated the ability to inhibit FLT3 receptor signaling and cell proliferation, and it induced apoptosis in leukemic cells expressing ITD and TKD mutant FLT3 receptors or overexpressing wild type FLT3 and PDGF receptors. Midostaurin also demonstrated the ability to inhibit KIT signaling, cell proliferation and histamine release and induce apoptosis in mast cells.

    12.2 Pharmacodynamics

    Cardiac Electrophysiology

    The effect of RYDAPT (75 mg twice daily for 3 days) on the QTc interval was evaluated in a randomized, placebo and moxifloxacin controlled, multiple-dose, blinded, parallel study. There was no clinically significant prolongation of QTc interval or relationship between changes in QTc and concentrations for midostaurin and its active metabolites (CGP62221 and CGP52421). The study duration was not long enough to estimate the effects of the metabolite CGP52421 on the QT/QTc interval.

    In pooled clinical studies in patients with advanced SM, 4.7% patients had a post-baseline QTcF > 480 ms, no patients had a QTcF > 500 ms, and 6.3% patients had a QTcF > 60 ms compared to baseline.

    In a randomized placebo-controlled study in patients with AML, the proportion of patients with QTc prolongation was higher in patients randomized to midostaurin as compared to placebo (QTcF > 480 ms: 10.1% vs 5.7%; QTcF > 500 ms: 6.2% vs 2.6%; QTcF > 60 ms: 18.4% vs 10.7%).

    12.3 Pharmacokinetics

    Midostaurin exhibits time-dependent pharmacokinetics with an initial increase in minimum concentrations (Cmin) that reach the highest Cmin concentrations during the first week followed by a decline to a steady-state after approximately 28 days. The pharmacokinetics of the CGP62221 showed a similar trend. The plasma concentrations of CGP52421 continued to increase after one month of treatment.

    The highest Cmin and steady-state of midostaurin, CGP62221, and CGP52421 were similar when RYDAPT was administered with food at a dose of 50 mg twice daily or 100 mg twice daily.

    Absorption

    The time to maximal concentrations (Tmax) occurred between 1 to 3 hours post dose in the fasted state.

    Effect of Food

    Midostaurin exposure, represented by area under the curve over time to infinity (AUCinf), increased 1.2-fold when RYDAPT was coadministered with a standard meal (457 calories, 50 g fat, 21 g proteins, and 18 g carbohydrates) and 1.6-fold when coadministered with a high-fat meal (1007 calories, 66 g fat, 32 g proteins, and 64 g carbohydrates) compared to when RYDAPT was administered in a fasted state. Midostaurin maximum concentrations (Cmax) were reduced by 20% with a standard meal and by 27% with a high-fat meal compared to a fasted state. Tmax was delayed when RYDAPT was administered with a standard meal or a high-fat meal (median Tmax = 2.5 hrs to 3 hrs) [see Dosage and Administration (2.5)].

    Distribution

    Midostaurin has an estimated geometric mean volume of distribution (% coefficient of variation) of 95.2 L (31%). Midostaurin and its metabolites are distributed mainly in plasma in vitro. Midostaurin, CGP62221, and CGP52421 are greater than 99.8% bound to plasma protein in vitro. Midostaurin is mainly bound to α1-acid glycoprotein in vitro.

    Elimination

    The geometric mean terminal half-life (% coefficient of variation) is 19 hours (39%) for midostaurin, 32 hours (31%) for CGP62221 and 482 hours (25%) for CGP52421

    Metabolism

    Midostaurin is primarily metabolized by CYP3A4. CGP62221 and CGP52421 (mean ± standard deviation) account for 28 ± 2.7% and 38 ± 6.6% respectively of the total circulating radioactivity.

    Excretion

    Fecal excretion accounted for 95% of the recovered dose with 91% of the recovered dose excreted as metabolites and 4% of the recovered dose as unchanged midostaurin. Only 5% of the recovered dose was found in urine.

    Specific Populations

    Age (20-94 years), sex, race, and mild (total bilirubin greater than 1.0 to 1.5 times the upper limit of normal (ULN) or aspartate aminotransferase (AST) greater than the ULN) or moderate (total bilirubin 1.5 to 3.0 times the ULN and any value for AST) hepatic impairment or renal impairment (creatinine clearance (CLCr) ≥ 30 mL/min) did not have clinically meaningful effects on the pharmacokinetics of midostaurin, CGP62221, or CGP52421. The pharmacokinetics of midostaurin in patients with baseline severe hepatic impairment (total bilirubin greater than 3.0 times the ULN and any value for AST) or severe renal impairment (CLCr 15 to 29 mL/min) is unknown.

    Drug Interaction Studies

    Clinical Studies

    Effect of Strong CYP3A4 Inhibitors on Midostaurin

    Coadministration of ketoconazole (400 mg daily for 10 days) with a single dose of RYDAPT (50 mg) on Day 6 increased AUCinf of midostaurin by 10.4-fold and CGP62221 by 3.5-fold and area under the curve over time to last measurable concentrations (AUC0-t) of CGP52421 by 1.2-fold compared to a single RYDAPT dose coadministered with placebo [see Drug Interactions (7.1)].

    Coadministration of itraconazole (100 mg twice daily on Days 22-28 for 13 doses) with multiple doses of RYDAPT (100 mg twice daily on Days 1 to 2 and 50 mg twice daily on Days 3 to 28) increased Day 28 Cmin concentrations of midostaurin by 2.1-fold, CGP62221 by 1.2-fold, and CGP52421 by 1.3-fold compared to the respective Day 21 Cmin concentrations with RYDAPT alone [see Drug Interactions (7.1)].

    Effect of Strong CYP3A4 Inducers on Midostaurin

    Coadministration of rifampicin (600 mg daily on Days 1 to 14) with a single dose of RYDAPT (50 mg) on Day 9 decreased AUCinf of midostaurin by 96% and CGP62221 by 92% and AUC0-t of CGP52421 by 59% [see Drug Interactions (7.1)].

    Effect of Midostaurin on Sensitive CYP3A substrates

    Midazolam (sensitive CYP3A substrate) AUCinf was not affected following 4 days of RYDAPT administration. The clinical relevance of this interaction is unknown as the RYDAPT was administered for only 4 days.

    In Vitro Studies

    Effects of Midostaurin on CYP Enzymes

    Midostaurin inhibits CYP1A2, CYP2C8, CYP2C9, CYP2D6, CYP2E1 and CYP3A; CGP62221 inhibits CYP1A2, CYP2C8, CYP2C9, and CYP3A; and CGP52421 inhibits CYP2D6 and CYP3A in vitro. Midostaurin, CGP52421, and CGP62221 induce CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, and CYP3A in vitro.

    Effects of Midostaurin on Transporters

    Midostaurin inhibits P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP); CGP52421 and CGP62221 inhibit organic anion transporter polypeptide (OATP) 1B1 in vitro.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenicity studies have not been performed with midostaurin.

    Midostaurin was not mutagenic in vitro in the bacterial reverse mutation assay (Ames test) or in Chinese hamster V97 cells. Midostaurin increased the frequency of polyploidy cells in an in vitro chromosomal aberrations assay in Chinese hamster ovary cells, but was not clastogenic in an in vivo rat bone marrow micronucleus assay when tested to the maximum tolerated dose (MTD) of 200 mg/kg (1200 mg/m2). This dose was approximately 20-fold the recommended human dose, based on body surface area.

    Reproductive toxicity was observed in a fertility study, in male and females rats given oral doses of midostaurin at 10, 30 and 60 mg/kg/day (approximately 0.01, 0.05, and 0.1 times, respectively, the AUC at the recommended human dose). In males, testicular degeneration and atrophy was observed at doses greater than or equal to 10 mg/kg/day and reduced sperm count and motility, and a decrease in reproductive organ weights were observed at 60 mg/kg/day. In females, increased resorptions, decreased pregnancy rate, and decreased number of implants and live embryos were observed at 60 mg/kg/day. In a 3-month toxicology study in dogs, there was inhibition of spermatogenesis at doses greater than or equal to 3 mg/kg/day (approximately 0.01 times the exposure at the recommended human dose).

  • 14 CLINICAL STUDIES

    14.1 Acute Myeloid Leukemia

    Study 1

    RYDAPT in combination with chemotherapy was investigated in a randomized, double-blind placebo-controlled trial of 717 patients with newly-diagnosed FLT3-mutated AML. In this study, FLT3 mutation status was determined prospectively with a clinical trial assay and verified retrospectively using the companion diagnostic LeukoStrat® CDx FLT3 Mutation Assay, which is an FDA-approved test for selection of patients with AML for RYDAPT treatment. Patients were stratified by FLT3 mutation status: TKD, ITD with allelic ratio less than 0.7, and ITD with allelic ratio greater than or equal to 0.7. Patients with acute promyelocytic leukemia or therapy-related AML were not eligible. Patients were randomized (1:1) to receive RYDAPT 50 mg twice daily (n = 360) or placebo (n = 357) with food on Days 8-21 in combination with daunorubicin (60 mg/m2 daily on Days 1 to 3) /cytarabine (200 mg/m2 daily on Days 1 to 7) for up to two cycles of induction and high dose cytarabine (3 g/m2 every 12 hours on Days 1, 3 and 5) for up to four cycles of consolidation, followed by continuous RYDAPT or placebo treatment according to initial assignment for up to 12 additional 28-day cycles. There was no re-randomization at the start of post consolidation therapy. Patients who proceeded to hematopoietic stem cell transplantation (SCT) stopped receiving study treatment.

    The randomized patients had a median age of 47 years (range 18-60 years), 44% were male, and 88% had a performance status of 0-1. AML was de novo onset in 95%. The percentage of patients with FLT3-ITD allelic ratio < 0.7, FLT3-ITD allelic ratio ≥ 0.7, and FLT3-TKD mutations were identical (per randomized FLT3 stratum) on both arms (48%, 30%, and 23%, respectively). Of the 563 patients with NPM1 testing, 58% had an NPM1 mutation. The two treatment groups were generally balanced with respect to the baseline demographics and disease characteristics, except that the placebo arm had a higher percentage of females (59%) than in the midostaurin arm (52%). NPM1 mutations were identified in 55% of patients tested on the midostaurin arm and 60% of patients tested on the placebo arm.

    A second course of induction was administered to 25% of the patients, 62% initiated at least one cycle of consolidation, 29% initiated maintenance, and 17% completed all 12 planned cycles of maintenance; 21% of the patients underwent SCT in first CR. The overall rate of SCT (induction failure, first CR or salvage after relapse) was 59% (214/360) of patients in the RYDAPT plus standard chemotherapy arm vs. 55% (197/357) in the placebo plus standard chemotherapy arm. All patients were followed for survival.

    Efficacy was established on the basis of overall survival (OS), measured from the date of randomization until death by any cause. The primary analysis was conducted after a minimum follow-up of approximately 3.5 years after the randomization of the last patient. RYDAPT plus standard chemotherapy was superior to placebo plus standard chemotherapy in OS [HR 0.77; 95% confidence interval (CI) 0.63, 0.95; 2 sided p = 0.016] (Figure 1). Because survival curves plateaued before reaching the median, median survival could not be reliably estimated.

    Figure 1: Kaplan-Meier Curve for Overall Survival in Study 1

    Figure

    The analysis of event-free survival (EFS), defined as a failure to obtain a complete remission (CR) within 60 days of initiation of protocol therapy, or relapse, or death from any cause, showed a statistically significant improvement with a median of 8.2 months for RYDAPT plus standard chemotherapy versus 3.0 months for placebo plus standard chemotherapy with HR 0.78 (95% CI 0.66, 0.93) and 2 sided p = 0.005. In an exploratory analysis of EFS defined as a failure to obtain a CR any time during induction, or relapse, or death from any cause with failures assigned as an event on study day 1, the median EFS was 10.6 months for RYDAPT plus standard chemotherapy versus 5.6 months for placebo plus standard chemotherapy with HR 0.72 (95% CI 0.61, 0.86).

    14.2 Systemic Mastocytosis

    Study 2

    A single-arm, open-label, multicenter trial evaluated the efficacy of RYDAPT as a single agent in ASM, SM-AHN, and MCL, collectively referred to as advanced SM. The study enrolled 116 adult patients with relapse or progression to 0, 1, or 2 prior regimens for SM. The study excluded patients with serum creatinine > 2.0 mg/dL, hepatic transaminases > 2.5 x upper limit of normal (ULN) or > 5 x ULN if disease-related, total bilirubin > 1.5 x ULN or > 3 x ULN if disease-related, QTc > 450 msec, cardiovascular disease including left-ventricular ejection fraction < 50%, or any pulmonary infiltrates. In addition, the study excluded patients with acute-stage or life-threatening AHN. Patients received RYDAPT 100 mg orally twice daily in 28-day cycles until disease progression or intolerable toxicity.

    Of the 116 patients treated, a study steering committee identified 89 patients who had measurable C-findings and were evaluable for response. The median age in this group was 64 years (range 25 to 82), 64% of patients were male, and nearly all patients (97%) were Caucasian. Among these patients, 36% had prior therapy for SM, and 82% had the KIT D816V mutation detected at baseline. Their median duration of treatment was 11 months (range < 1 to 68 months), with treatment ongoing in 17%.

    Efficacy was established on the basis of confirmed complete remission (CR) plus incomplete remission (ICR) by 6 cycles of RYDAPT by modified Valent criteria for ASM and SM-AHN (Table 7). Table 7 shows responses to RYDAPT according to modified Valent criteria. Confirmed major or partial responses occurred in 46 of 73 patients with a documented KIT D816V mutation, 7 of 16 with wild-type or unknown status with respect to KIT D816V mutation, and 21 of 32 having prior therapy for SM.

Response after 6 cycles of RYDAPT was determined using a computational algorithm. The efficacy of RYDAPT for MCL was based on the CR results by these criteria. There were 115 patients evaluable for response assessment, of whom 47 (41%) had prior therapy for SM, and 93 (81%) had a documented D816V mutation at baseline. Table 8 provides the results of this analysis. Overall response by modified IWG-MRT-ECNM criteria was reported for 16 (17%) of 93 patients with a documented D816V mutation, and in 8 (17%) of 47 patients having prior therapy for SM.

    Study 3

    Study 3 was a single-arm, multicenter, open-label trial of 26 patients with advanced SM. RYDAPT was administered orally at 100 mg twice daily with food. The median age in this group was 64 years, 58% of patients were male and most were Caucasian (81%). Eligibility criteria were similar to Study 2. By Valent criteria per investigator assessment, of 17 patients with SM-AHN, 10 achieved a response (1 partial, 9 major) by 2 cycles that was sustained for at least 8 weeks. Patients who received concomitant corticosteroids were included. Of the 6 patients with MCL, 1 achieved partial response and 1 achieved major response. Median DOR for either group had not been reached, with DOR ranging from 3.4+ to 79.2+ months in patients with SM-AHN and 28.6+ to 32.1+ months in patients with MCL. The subtype of SM in the remaining 3 patients was unconfirmed.
