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.

( 6.1 ) Most common select laboratory abnormalities (≥ 20%) are lymphocyte count decreased, leukocyte count decreased, platelet count decreased, neutrophil count decreased, calcium corrected decreased, lipase increased, cholesterol increased, uric acid increased, alanine aminotransferase (ALT) increased, alkaline phosphatase (ALP) increased, hemoglobin decreased, triglycerides increased, creatine kinase increased, amylase increased, and aspartate aminotransferase (AST) increased.

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 pooled safety population described in the WARNINGS AND PRECAUTIONS reflect exposure to SCEMBLIX at 10 mg to 200 mg orally twice daily (between 0.25 to 5 times the recommended dosage for the 80 mg daily dosage and between 0.05 times and up to the recommended dosage for the 200 mg twice daily dosage) in 556 patients enrolled in one of three clinical trials, including patients with Ph+ CML in CP receiving SCEMBLIX as monotherapy: study CABL001J12301 (ASC4FIRST), study CABL001A2301 (ASCEMBL) and study CABL001X2101 [see Clinical Studies (14)] .

Among the 556 patients receiving SCEMBLIX, the median duration of exposure to SCEMBLIX was 123 weeks (range, 0.1 to 439 weeks), with 79% of patients exposed for at least 48 weeks and 71% of patients exposed for at least 96 weeks, respectively.

The most common (≥ 20%) adverse reactions in patients who received SCEMBLIX were musculoskeletal pain, rash, fatigue, upper respiratory tract infection, headache, abdominal pain, arthralgia, and diarrhea.

Adverse Reactions in Patients with Newly Diagnosed Ph+ CML-CP The ASC4FIRST clinical trial randomized 405 patients with newly diagnosed Ph+ CML-CP to receive SCEMBLIX 80 mg once daily or investigator selected tyrosine kinase inhibitors (IS-TKIs).

IS-TKIs included imatinib (400 mg once daily), nilotinib (300 mg twice daily), dasatinib (100 mg once daily), or bosutinib (400 mg once daily) [see Clinical Studies (14.1)] .

The safety population (received at least 1 dose of SCEMBLIX) included 200 patients with newly diagnosed Ph+ CML-CP.
