Treatment: Drugs: AZD2811
AZD2811 will be administered by IV infusion with the specified dose level as reported in arms in 28-day cycles.

Treatment: Drugs: Azacitidine
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.

Treatment: Drugs: Venetoclax
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.

Participants are unsuitable for intensive induction therapy if they are:
* 75 years or

* 75 years of age with clinically significant cardiac or pulmonary dysfunction unrelated to leukaemia, as reflected by at least 1 of the following criteria: Left ventricular ejection fraction (LVEF) =50% Diffusing capacity of the lungs for carbon monoxide (DLCO) =65% of expected Forced expiratory volume 1(FEV1) =65% of expected Chronic stable angina any significant co-morbidities which in the opinion of the treating physician makes the participant unsuitable for intensive induction therapy. This must be documented by the study monitor.
2. AML participants who are unlikely to demonstrate rapid progression such that they would be unable to complete the first cycle of therapy.
3. Provision of signed and dated, written informed consent prior to any study-specific procedures, sampling and analyses.
4. Aged at least 18 years
5. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-2.

Summary
Brief summary
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
