Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - siremadlin
Treatment: Drugs - venetoclax
Treatment: Drugs - azacitidine

Experimental: Arm 1: Unfit adult participants with AML who responded sub-optimally to standard of care - Unfit adult participants with AML who responded sub-optimally to at least 2 and not more than 4 cycles ( 1 cycle=28 days) of first-line venetoclax plus azacitidine therapy

Experimental: Arm 2: Newly diagnosed unfit adult participants with high-risk AML - Unfit adult participants with newly diagnosed AML and with adverse genetic risk stratification (according to ELN 2022)(Except TP53 mutation positive participants).


Treatment: Drugs: siremadlin
Siremadlin is a capsule taken orally once a day (QD) and comes in 10 mg, 20 mg and 30 mg strengths

Treatment: Drugs: venetoclax
Venetoclax is a tablet taken orally once a day (QD) and comes in 10 mg, 50 mg and 100 mg strengths.

Treatment: Drugs: azacitidine
Azacitidine is a powder for suspension for injection or powder for solution for infusion taken intravenously or subcutaneously according to standard local clinical practice
