Brief Summary:

Acute myeloid leukemia (AML) is one of the most aggressive blood cancers, with a very low survival rate and few options for participants who are unable to undergo intensive chemotherapy, the current standard of care. This study is to evaluate how safe lemzoparlimab is and how it moves within the body when used along with azacitidine and/or venetoclax in adult participants with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Adverse events and maximum tolerated dose (MTD) of lemzoparlimab will be assessed.

Lemzoparlimab (TJ011133) is being evaluated in combination with azacitidine and venetoclax for the treatment of acute myeloid leukemia (AML) and with azacitidine with/without venetoclax for myelodysplastic syndrome (MDS). Study doctors place the participants in 1 of 5 groups, called treatment arms. Each group receives a different treatment. Adult participants with a diagnosis of AML or MDS will be enrolled. Around 80 participants will be enrolled in the study in approximately 50 sites worldwide.

Participants will receive lemzoparlimab (IV) once weekly (Q1W), venetoclax oral tablets once daily (QD) for 28 days (AML participants) or 14 days (MDS participants) and Azacitidine by SC or IV route QD for 7 days of each 28-day cycle.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests and checking for side effects.
