Brief Summary:
A Phase 1/2, Open-label, Multicenter, Dose Escalation and Expansion Study of the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Tuspetinib (HM43239) in Patients with Relapsed or Refractory Acute Myeloid Leukemia (AML)

Condition or disease Intervention/treatment Phase
Relapsed or Refractory Acute Myeloid Leukemia Drug: Tuspetinib Drug: Venetoclax Oral Tablet Phase 1 Phase 2

Detailed Description:
This is a Phase 1/2, open-label, multi-center study to assess the efficacy, safety, tolerability, pharmacokinetics, including recommended phase 2 dose (RP2D) of tuspetinib (HM43239) monotherapy in subjects with relapsed or treatment-refractory acute myeloid leukemia (AML).

Other Name: HM43239

Experimental: Part C Dose Expansion (tuspetinib as a single agent)
Part C, dose expansion, consists of 2 arms (tuspetinib as a single agent or tuspetinib plus venetoclax). Patients will be randomly assigned to either arm based on the number of slots available. The initial tuspetinib dose for the single arm will be 120mg.
Drug: Tuspetinib
Daily (QD), continuous dosing
Other Name: HM43239

Experimental: Part C Dose Expansion (Combination Arm - tuspetinib and venetoclax)
