SCEMBLIX®▼ (asciminib) resulted in fewer all-grade and grade ≥3 AEs vs bosutinib2,3
The ASCEMBL trial population was not restricted to Ph+ patients with CML-CP.2 SCEMBLIX is indicated in adults with Ph+ CML-CP previously treated with two or more TKIs and without a known T315I mutation.1
Patients receiving SCEMBLIX and bosutinib, respectively, experienced:
WEEK 24:2
WEEK 96:3
Most frequent all-grade AEs by Week 96 (occurring in ≤20% of patients in any treatment arm)3
Analysis ongoing at the time of data cut-off: 6 October 2021.
aThrombocytopenia includes: thrombocytopenia and platelet count decreased.
bNeutropenia includes: neutropenia and neutrophil count decreased.
Adapted from Hochhaus, et al. 2023.3
Please refer to the Summary of Product Characteristics for further information on risk management, key contraindications, warnings and side effects.1
By Week 96, all-grade AEs leading to dose adjustment or interruption, occurred in 42.3% of patients receiving SCEMBLIX vs 64.5% of patients receiving bosutinib.3
The median duration of exposure (range) by the data cutoff was 23.7 (0.0–46.2) months on SCEMBLIX and 7.0 (0.2–43.3) months on bosutinib.3
Patients on SCEMBLIX experienced fewer all-grade/grade ≥3 AEs vs bosutinib and required fewer dose modifications2,3
Patients taking SCEMBLIX experienced lower treatment discontinuation vs bosutinib2
Discontinuation rates due to AEs at Week 242
Patients still on treatment at time of cut off*3
Consistent with the primary analysis, the most common AEs leading to discontinuation were thrombocytopenia (3.2%) and neutropenia (2.6%) for SCEMBLIX and increased ALT (3.9%) and neutropenia (3.9%) for bosutinib at the cut-off date.*

Myelosuppression1
Thrombocytopenia, neutropenia and anaemia occurred in patients receiving SCEMBLIX. Severe (NCI-CTCAE grade 3 or 4) thrombocytopenia and neutropenia events were reported during treatment with SCEMBLIX. Myelosuppression was generally reversible and managed by temporarily withholding treatment. Complete blood counts should be performed every two weeks for the first 3 months of treatment and then monthly thereafter, or as clinically indicated. Patients should be monitored for signs and symptoms of myelosuppression.
Based on the severity of thrombocytopenia and/or neutropenia, the dose should be reduced, temporarily withheld or permanently discontinued.
Pancreatic toxicity1
Pancreatitis and asymptomatic elevation of serum lipase and amylase, including severe reactions, occurred in patients receiving SCEMBLIX.
Serum lipase and amylase levels should be assessed monthly during treatment with SCEMBLIX, or as clinically indicated. Patients should be monitored for signs and symptoms of pancreatic toxicity. More frequent monitoring should be performed in patients with a history of pancreatitis. If serum lipase and amylase elevation are accompanied by abdominal symptoms, treatment should be temporarily withheld and appropriate diagnostic tests should be considered to exclude pancreatitis.
Based on the severity of serum lipase and amylase elevation, the dose should be temporarily withheld, reduced or permanently discontinued.
QT prolongation1
QT prolongation occurred in patients receiving SCEMBLIX.
It is recommended that an electrocardiogram is performed prior to the start of treatment with SCEMBLIX, and monitored during treatment as clinically indicated. Hypokalaemia and hypomagnesaemia should be corrected prior to SCEMBLIX administration and monitored during treatment as clinically indicated.
Caution should be exercised when administering SCEMBLIX concomitantly with medicinal products with a known risk of torsades de pointes, or in patients who have a history of or predisposition for QTc prolongation or uncontrolled or significant cardiac disease including bradycardia.
Hypertension1
Hypertension, including severe hypertension, occurred in patients receiving SCEMBLIX.
Hypertension should be monitored and managed using standard antihypertensive therapy during treatment with SCEMBLIX as clinically indicated.
Hepatitis B reactivation1
Reactivation of hepatitis B virus (HBV) has occurred in patients who are chronic carriers of this virus following administration of other BCR::ABL1 tyrosine kinase inhibitors (TKIs). Patients should be tested for HBV infection before the start of treatment with SCEMBLIX.
HBV carriers who require treatment with SCEMBLIX should be closely monitored for signs and symptoms of active HBV infection throughout therapy and for several months following termination of therapy.
Lactose1
Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.
Sodium1
This medicinal product contains less than 1 mmol sodium (23 mg) per film-coated tablet, that is to say essentially “sodium free.”
Patients taking SCEMBLIX experienced lower treatment discontinuation vs bosutinib2
