Novartis Wins Expanded Approval for Scemblix
FDA has granted an accelerated approval to Novartis for its supplemental NDA for Scemblix (asciminib) for the drug’s expanded use in treating newly diagnosed adult patients with Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase (Ph+ CML-CP). Currently, Scemblix is approved for adult patients with Ph+ CML-CP who have been treated previously with two or more tyrosine kinase inhibitors.
The submission was based on data from the Phase 3 ASC4FIRST study comparing Scemblix against investigator-selected (IS) tyrosine kinase inhibitors (imatinib, nilotinib, dasatinib, and bosutinib), which are the standard-of-care (SoC). “Scemblix demonstrated superior major molecular response (MMR) rates in both primary endpoints at week 48 vs. IS SoC TKIs (68% vs. 49.0%) and imatinib alone (69% vs. 40%),” Novartis says. “In newly diagnosed patients, the safety profile was consistent with previous registration studies, with no new safety concerns observed.”
