Glasdegib: uses, dosing, side effects & brands

The following clinically-significant adverse reactions are described elsewhere in the labeling: • QTc Interval Prolongation [see Warnings and Precautions (5.2) ] • Musculoskeletal Adverse Reactions [see Warnings and Precautions (5.3) ] Most common adverse reactions (incidence ≥20%) are anemia, fatigue, hemorrhage, febrile neutropenia, musculoskeletal pain, nausea, edema, thrombocytopenia, dyspnea, decreased appetite, dysgeusia, mucositis, constipation, and rash. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer, Inc. at 1-800-438-1985 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. The safety profile of DAURISMO is based on experience in the BRIGHT AML 1003 study for 111 adults with newly-diagnosed AML and 14 adults with other conditions for which DAURISMO is not indicated [see Clinical Studies (14) ] . Patients were treated with DAURISMO 100 mg daily in combination with low-dose cytarabine (N=84) or low-dose cytarabine alone (N=41). The median duration of treatment in the DAURISMO with low-dose cytarabine arm was 83 days (range 3 to 972 days), and the median duration of…

Table 5. Drug Interactions with DAURISMO Strong CYP3A Inhibitors Clinical Impact • Co-administration of DAURISMO with strong CYP3A inhibitors increased glasdegib plasma concentrations [see Clinical Pharmacology (12.3) ]. • Increased glasdegib concentrations may increase the risk of adverse reactions including QTc interval prolongation [see Warnings and Precautions (5.2) ] . Prevention or Management • Consider alternative therapies that are not strong CYP3A4 inhibitors during treatment with DAURISMO. • Monitor patients for increased risk of adverse reactions including QTc interval prolongation [see Warnings and Precautions (5.2) ]. Strong and Moderate CYP3A Inducers Clinical Impact Co-administration of DAURISMO with strong and moderate CYP3A inducers decreased glasdegib plasma concentrations [see Clinical Pharmacology (12.3) ] . • Decreased glasdegib concentrations may reduce efficacy. Prevention or Management • Avoid co-administration of DAURISMO with strong and moderate CYP3A4 inducers. • If co-administration of DAURISMO with moderate CYP3A4 inducers cannot be avoided, increase the dose of DAURISMO [see Dosage and Administration (2.3) ] . QTc Prolonging Drugs Clinical Impact Co-administration of DAURISMO with QTc prolonging drugs may increase the risk of QTc interval prolongation [see Warnings and Precautions (5.2) ]. Prevention or Management • Avoid co-administration of QTc prolonging drugs with DAURISMO or replace with alternative therapies. • If co-administration of a QTc prolonging drug is unavoidable, monitor patients for increased risk of QTc interval prolongation [see Warnings and Precautions (5.2) ]. • Strong CYP3A4 Inhibitors: Consider alternative therapies that are not strong CYP3A4 inhibitors or monitor for increased risk of adverse reactions, including QTc interval prolongation. ( 7 ) • Strong CYP3A4 Inducers: Avoid concomitant use with DAURISMO. ( 7 ) • Moderate CYP3A4 Inducers: Avoid concomitant use with DAURISMO. If, concomitant use cannot be avoided, increase the dose of DAURISMO. ( 2.3 , 7 ) • QTc Prolonging Drugs: Avoid co-administration with DAURISMO. If co-administration is unavoidable, monitor for increased risk of QTc interval prolongation. ( 7 )
