Phase 3 Trial of ICLUSIG (ponatinib) Met Primary Endpoint in Newly-Diagnosed Ph+ ALL, a Setting with No Targeted Treatments Approved in the US

Takeda announced that the randomized, Phase 3 PhALLCON trial met its primary endpoint, demonstrating that adult patients with newly-diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) treated with ICLUSIG (ponatinib) plus reduced-intensity chemotherapy achieved higher rates of minimal residual disease (MRD)-negative complete remission (CR) compared to imatinib. MRD-negativity is associated with improvement in long-term outcomes for patients, as reported in literature. ICLUSIG is the only pan-mutational and third-generation tyrosine kinase inhibitor (TKI), targeting BCR::ABL1 and all known single, treatment-resistant mutations, including the most resistant T315I mutation.

“Ph+ ALL is a fast-progressing disease with no targeted treatments currently approved in the frontline for patients in the U.S. There is an urgent need for an effective treatment that can suppress the development of difficult-to-treat mutations, which are associated with poor long-term outcomes,” said Awny Farajallah, MD, Head of Global Medical Affairs Oncology at Takeda. “We are excited to see how ICLUSIG may be able to address this gap in care for these patients and look forward to sharing the results.”

The PhALLCON study is a Phase 3 randomized, international, open-label multicenter trial evaluating the efficacy and safety of ICLUSIG versus imatinib in combination with reduced-intensity chemotherapy as a frontline therapy for adult patients with newly diagnosed Ph+ ALL. In the trial, no new safety signals were observed. Data from this trial will be discussed with regulatory agencies and shared with the scientific community in the future.
