Interventions

• AZD2811 — DRUG
  AZD2811 will be administered by IV infusion with the specified dose level as reported in arms in 28-day cycles.
• Azacitidine — DRUG
  Azacitidine is supplied in vials of 25 mg/mL powder for suspension for injection. After reconstitution, each vial contains a maximum of 100 mg. Participants should be pre-medicated for nausea and vomiting according to institutional standards before receiving azacitidine. Participants will receive 75 mg/m² on Days 1 through 7 or for 5 consecutive weekdays with rest on the 2 weekend days, and azacitidine dosing the first 2 weekdays of the next week of each 28-day cycle.
• Venetoclax — DRUG
  Venetoclax (VENCLEXTA®) is approved by the FDA for use in combination with azacitidine, or decitabine, or low-dose cytarabine for the treatment of newly-diagnosed AML in adults who are age 75 years or older, or who have comorbidities that preclude use of intensive induction chemotherapy. Venetoclax is planned to be given at a dose of 100 mg orally (PO) on Day 1 and 200 mg (PO) on Days 2- 28 of each 28-day cycle or 100 mg orally (PO) on Day 1, 200 mg PO on Day 2, and 400 mg PO from Days 3 to 28 of each 28-day cycle. The third participant in Group 3 Arm A will only be enrolled after the first 2 participants will receive ≥2 weeks of treatment and have shown no evidence of toxicity observed to be compatible with a DLT.

Study Details

This is a Phase I/II clinical study to determine the maximum tolerated dose (MTD), and schedule, safety, tolerability, pharmacokinetics, and pharmacodynamics of AZD2811 monotherapy or with combination agent(s) in relapsed/refractory acute myeloid leukaemia (AML) participants or treatment-naïve AML participants not eligible for intensive induction therapy. In addition, the study will explore the potential clinical activity by assessing anti-tumour activity in participants. The study was terminated early as a result of AstraZeneca's strategic review across the AZD2811 programme. Part A data were collected for initial cohorts; the MTD/recommended Phase 2 dose (RP2D) dose and schedule of AZD2811 monotherapy or with combination agents were not determined. Part B of the study was not initiated
