Midostaurin is a kinase inhibitor sold in the U.S. under 2 brand and generic names, for acute myeloid leukemia, hematologic neoplasms and systemic mastocytosis. Below: what the FDA label says, every product that contains it, what the pills look like, and its recall record.
From the FDA label for Rydapt (application NDA207997). Other midostaurin products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.
AML : 50 mg orally twice daily with food. ( 2.1 , 2.2 , 2.4 ) ASM, SM-AHN, and MCL : 100 mg orally twice daily with food. ( 2.3 , 2.4 ) 2.1 Patient Selection Select patients for the treatment of AML with RYDAPT based on the presence of FLT3 mutation positivity [see Clinical Studies (14)] . Information on FDA-approved tests for the detection of FLT3 mutation in AML is available at: http://www.fda.gov/CompanionDiagnostics. 2.2 Recommended Dosage in Acute Myeloid Leukemia The recommended dose of RYDAPT for patients with AML is 50 mg orally twice daily with food on Days 8 to 21 of each cycle of induction with cytarabine and daunorubicin and on Days 8 to 21 of each cycle of consolidation with high-dose cytarabine. For a description of the experience with single-agent treatment with RYDAPT beyond induction and consolidation [see Clinical Studies (14.1)] . 2.3 Recommended Dosage in ASM, SM-AHN, and MCL The recommended dose of RYDAPT for patients with ASM, SM-AHN, and MCL is 100 mg orally twice daily with food. Continue treatment until disease progression or unacceptable toxicity occurs. Table 1 provides recommendations for dose modifications of RYDAPT in patients with ASM, SM-AHN, and MCL. Monitor patients for toxicity at least weekly for the first 4 weeks, every other week for the next 8 weeks, and monthly thereafter while on treatment. Table 1: RYDAPT…
The following serious adverse reactions are described elsewhere in the labeling: Pulmonary Toxicity [see Warnings and Precautions (5.2)] AML : The most common adverse reactions (≥ 20%) were febrile neutropenia, nausea, mucositis, vomiting, headache, petechiae, musculoskeletal pain, epistaxis, device-related infection, hyperglycemia, electrocardiogram (ECG) QT prolonged, and upper respiratory tract infection. ( 6.1 ) ASM, SM-AHN, or MCL : The most common adverse reactions (≥ 20%) were nausea, vomiting, diarrhea, edema, musculoskeletal pain, abdominal pain, fatigue, upper respiratory tract infection, constipation, pyrexia, headache, and dyspnea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Novartis Pharmaceuticals Corporation at 1-888-669-6682 and/or at https://report.novartis.com/ or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 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…

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)]. Hypersensitivity to midostaurin or any of the excipients. ( 4 )
Strong CYP3A4 Inhibitors : Strong CYP3A4 inhibitors may increase exposure to midostaurin and its active metabolites. Consider alternative therapies that do not strongly inhibit CYP3A4 or monitor for increased risk of adverse reactions. ( 7.1 ) Strong CYP3A4 Inducers : Avoid concomitant use as strong CYP3A4 inducers decrease exposure to midostaurin and its active metabolites. ( 7.1 ) CYP2B6, BCRP, OATP1B1 Substrates : Dose adjustments for coadministered CYP2B6, BCRP, and OATP1B1 substrates may be necessary with RYDAPT. ( 7.2 ) 7.1 Effect of Other Drugs on RYDAPT 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 a The 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). b The induction potency of St. John’s wort may vary widely based on preparation. Clinical Impact Coadministration of RYDAPT with strong CYP3A inhibitors may increase midostaurin concentrations. The increase in midostaurin concentrations may be pronounced if strong CYP3A…
