This indication is approved under accelerated approval based on major molecular response rate [see Clinical Studies (14.1)] . Continued approval for this indication may be contingent upon verification of clinical benefit in a confirmatory trial(s). Previously treated Ph+ CML in CP. Ph+ CML in CP with the T315I mutation. SCEMBLIX is a kinase inhibitor indicated for the treatment of adult patients with: Newly diagnosed Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML) in chronic phase (CP).
Dosage

( 2.1 ) Recommended Dosage in Ph+ CML in CP with the T315I Mutation: 200 mg orally twice daily. ( 2.2 ) Avoid food for at least 2 hours before and 1 hour after taking SCEMBLIX. ( 2.5 ) Swallow tablets whole. Do not break, crush, or chew the tablets. ( 2.5 ) 2.1 Recommended Dosage in Patients with Newly Diagnosed or Previously Treated Ph+ CML-CP The recommended dose of SCEMBLIX is 80 mg taken orally once daily at approximately the same time each day or 40 mg orally twice daily at approximately 12-hour intervals. The recommended dose of SCEMBLIX is taken orally without food.
Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions can occur with SCEMBLIX and are discussed in greater detail in other sections of the labeling: Myelosuppression [see Warnings and Precautions (5.1)] Pancreatic Toxicity [see Warnings and Precautions (5.2)] Hypertension [see Warnings and Precautions (5.3)] Hypersensitivity [see Warnings and Precautions (5.4)] Cardiovascular Toxicity [see Warnings and Precautions (5.5)] Most common adverse reactions (≥ 20%) are musculoskeletal pain, rash, fatigue, upper respiratory tract infection, headache, abdominal pain, arthralgia, and diarrhea.
Interactions
7 DRUG INTERACTIONS Strong CYP3A4 Inhibitors: Closely monitor for adverse reactions during concomitant use of SCEMBLIX at 200 mg twice daily. ( 7.1 ) Itraconazole Oral Solution Containing Hydroxypropyl-β-cyclodextrin: Avoid concomitant use of SCEMBLIX at all recommended doses. ( 7.1 ) Certain Substrates of CYP3A4: Closely monitor for adverse reactions during concomitant use of SCEMBLIX at 80 mg total daily dose. Avoid use of SCEMBLIX at 200 mg twice daily. ( 7.2 ) Substrates of CYP2C9: Avoid concomitant use of SCEMBLIX at all recommended doses. 80 mg total daily dose: If unavoidable, reduce the CYP2C9 substrate dosage as necessary. ( 7.2 ) 200 mg twice daily: If unavoidable, consider alternative therapy with non-CYP2C9 substrate.
Warnings
5 WARNINGS AND PRECAUTIONS Myelosuppression: Severe thrombocytopenia and neutropenia events may occur. Monitor complete blood counts regularly during therapy and manage by treatment interruption or dose reduction. ( 2.4 , 5.1 ) Pancreatic Toxicity: Monitor serum lipase and amylase. Interrupt, then resume at reduced dose or discontinue SCEMBLIX based on severity. Evaluate for pancreatitis when lipase elevation is accompanied by abdominal symptoms. ( 2.4 , 5.2 ) Hypertension: Monitor blood pressure and manage hypertension as clinically indicated. Interrupt, dose reduce, or stop SCEMBLIX if hypertension is not medically controlled. ( 2.4 , 5.3 ) Hypersensitivity: May cause hypersensitivity reactions. 4 CONTRAINDICATIONS None. None. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Based on findings from animal studies and the mechanism of action, SCEMBLIX can cause embryo-fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)] . There are no available data on SCEMBLIX use in pregnant women to evaluate a drug-associated risk. Animal reproduction studies in pregnant rats and rabbits demonstrated that oral administration of asciminib during organogenesis induced structural abnormalities, embryo-fetal mortality, and alterations to growth ( see Data ).
