Ponatinib bests older TKIs against Ph+ALL

For 3-year OS, however, ponatinib was superior to the pooled data for the other TKIs, at 79% versus 50%, translating into an OR of 4.49 (P = .050).

The authors acknowledged that the study was limited by differences in treatment regimens and centers, and a limited ability to adjust for patient characteristics, due to the study’s reliance on only those covariates published across different studies. Head-to-head comparison trials are needed to confirm their results, they noted.

Nonetheless, “[w]e believe that the improved efficacy of ponatinib combined with chemotherapy for newly diagnosed Ph+ALL might prevent the need for allogeneic SCT,” they wrote.

Ariad Pharmaceuticals funded the study. Dr. Jabbour and three coauthors reported research funding from the company; other study authors reported employment or other financial relationships with Ariad or its parent company Takeda.
