- At primary analysis, ASCEMBL met its primary endpoint of significant superiority in major molecular response rate at 24 weeks for asciminib (ABL001) vs. bosutinib in patients previously treated with two or more tyrosine-kinase inhibitors (TKIs)1
- Despite advances in chronic myeloid leukemia (CML) care, many patients are at risk of disease progression, and sequential TKI therapy may be associated with increased resistance and intolerance2-7
- By specifically targeting the ABL myristoyl pocket, STAMP inhibition has the potential to help address resistance and intolerance in later treatment lines for CML8-14; additional studies seek to evaluate asciminib in earlier lines of therapy15
- ASCEMBL results will be submitted for presentation at an upcoming medical meeting and shared with regulatory authorities; FDA has granted asciminib Fast Track designation
BASEL, Switzerland I August 26, 2020 I Novartis announced today that, at primary analysis, the Phase III ASCEMBL study met its primary endpoint of statistically significant superiority in major molecular response (MMR) rate at 24 weeks for asciminib (ABL001) vs. bosutinib1. The study evaluates asciminib – a novel investigational treatment specifically targeting the ABL myristoyl pocket (STAMP) – in adult patients with Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase (Ph+ CML-CP) previously treated with two or more tyrosine-kinase inhibitors (TKIs)1. Patients with failure or intolerance to the most recently administered TKI therapy were included in the trial1.
“Our ability to treat patients with TKIs changed CML care forever. However, the risk of disease progression is a reality for many patients – especially those who experience resistance to sequential TKI therapy or those who cannot adhere to treatment due to the daily impact of intolerable side effects16,” said John Tsai, MD, Head of Global Drug Development and Chief Medical Officer, Novartis. “We are incredibly grateful to the patients and investigators around the world who participated in this study. These results with asciminib are a testament to our commitment to further transform CML care – this time through STAMP inhibition, by exploiting a natural regulatory mechanism of the ABL kinase.”
Data from the ASCEMBL trial will be submitted for presentation at an upcoming medical meeting, and results will be shared with regulatory authorities. The U.S. Food and Drug Administration (FDA) has granted Fast Track designation for asciminib.
Findings from earlier studies of asciminib were presented during past annual meetings of the European Hematology Association, and some details can be found here13,14.
About asciminib (ABL001)
Asciminib (ABL001) is an investigational treatment specifically targeting the ABL myristoyl pocket (STAMP). As a STAMP inhibitor, asciminib may help address tyrosine-kinase inhibitor (TKI)-resistance and intolerance in later treatment lines of chronic myeloid leukemia (CML)8-14, and it is being studied in several clinical trials in hopes of helping patients across multiple treatment lines of CML7,10,11,13-15,17.
ASCEMBL is a Phase III, multicenter, open-label, randomized study comparing the oral investigational treatment asciminib (ABL001) versus bosutinib in patients with Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase (Ph+ CML-CP) previously treated with two or more tyrosine-kinase inhibitors (TKIs)1. Patients with failure or intolerance to the most recently administered TKI therapy were included in the trial1.
