Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - LY3410738
Treatment: Drugs - Venetoclax
Treatment: Drugs - Azacitidine

Experimental: Dose Escalation Arm A (Monotherapy) - Patients not requiring a strong cytochrome P450 3A4 (CYP3A4) inhibitor.

Experimental: Dose Escalation Arm B (Monotherapy) - Patients requiring a strong CYP3A4 inhibitor for active management or prevention of a lifethreatening condition, such as an azole administered to prevent invasive fungal infection.

Experimental: Dose Escalation Arm C (LY3410738, Venetoclax, and Azacitidine) - Patients with no prior venetoclax therapy and not requiring a strong CYP3A4 inhibitor for active treatment within 7 days of starting LY3410738.

Experimental: Cohort 1 - Patients with relapsed/refractory (R/R) AML harboring an IDH1 R132 mutation who have received a prior IDH inhibitor.

Experimental: Cohort 2 - Patients with R/R AML harboring an IDH1 R132 mutation who have not received a prior IDH inhibitor.

Experimental: Cohort 3 - Patients with R/R MDS, chronic myelomonocytic leukemia (CMML) or other advanced hematologic malignancy harboring an IDH1 R132 mutation.

Experimental: Cohort 4 - Patients with R/R AML, MDS, CMML or other advanced hematologic malignancy harboring IDH2 mutations.

Experimental: Cohort 5 - Patients with newly diagnosed AML, R/R AML, or other advanced hematologic malignancy harboring IDH1 and/or IDH2 mutations with no prior venetoclax therapy. Strong CYP3A4 inhibitor allowed but not required.
