Aptevo Therapeutics Inc. announced that APVO436, in combination with venetoclax and azacitidine, achieved a 100% clinical benefit rate (CBR) in venetoclax treatment naïve AML patients. The data, which was presented in a poster session at the 64thAmerican Society of Hematology (ASH) Annual Meeting and Exposition in New Orleans, also showed that APVO436, when given in combination with this standard-of-care regimen, was observed to be generally safe and well tolerated.
