Breakthrough for Novartis’ Scemblix in Leukemia
FDA has granted Novartis a breakthrough therapy designation for Scemblix (asciminib) for treating adult patients with newly diagnosed Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase. Novartis says the designation was based on positive data from the Phase 3 ASC4FIRST study, in which Scemblix met both primary endpoints with superior major molecular response rates at week 48 compared to investigator-selected tyrosine kinase inhibitors (imatinib, nilotinib, dasatinib and bosutinib) and compared to imatinib alone. Scemblix also showed a favorable safety and tolerability profile with fewer adverse events and treatment discontinuations vs. standard-of-care therapies, the company adds.
