Acute Myeloid Leukaemia Clinical Trial
Official title:
A Phase I/II, Open-Label, Multicentre 2-Part Study to Assess the Safety, Tolerability, Pharmacokinetics, and Efficacy of AZD2811 as Monotherapy or in Combination in Treatment-Naïve or Relapsed/Refractory Acute Myeloid Leukaemia Patients Not Eligible for Intensive Induction Therapy.

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

Eligibility | Inclusion criteria 1. AML participants who have either: (a) relapsed or are refractory to standard therapies (the participant may have been treated with standard therapy prior to the diagnosis of AML e.g. for MDS), OR (b) diagnosis of AML (bone marrow blasts = 20%), who are previously untreated for AML, and are not suitable for intensive induction therapy, as defined below (for AZD2811 monotherapy and HMA combination participants only i.e. inclusion criteria 1(b) may only be used to enrol a participant into Groups 1 and 2; previously untreated AML participants may not enrol into Group 3 unless they fulfil inclusion criteria 1(a) above). 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.
