Actinium Highlights Transcriptional Reprogramming as a Key Mechanism Underpinning Mutation-Agnostic Activity of Actimab-A in AML at the 2026 American Association of Cancer Research Annual Meeting

April 22, 2026 7:01 AM EDT

Actimab-A combinations enhanced in vivo AML cell killing across multiple preclinical models, independent of mutation status, when combined with standard-of-care targeted and non-targeted therapies including revumenib (menin-KMT2A inhibitor), gilteritinib (FLT3 inhibitor), and azacitidine (hypomethylating agent) - three pillars of modern AML treatment - supporting its potential role as a universal combination backbone

Transcriptional reprogramming identified as a central mechanism showing that Actimab-A combinations don't just add cytotoxicity, they reprogram AML cells from proliferation toward differentiation and apoptosis, providing the mechanistic basis for deeper, more durable MRD-negative responses and reinforcing Actimab-A's role as a...
