A Phase I/II Open-Label Multi-Centre Master Protocol to Evaluate the Safety and Efficacy of AZD0486 Monotherapy or in Combination With Other Anticancer Agents in Participants With Mature B-Cell Malignancies

Description

The purpose of this study is to assess the safety and efficacy of AZD0486 administered as monotherapy or in combination with other anticancer agents in participants with hematological malignancies.This is open-label, multi-center study to evaluate the safety and preliminary efficacy of AZD0486 administered as monotherapy and in combination with other anticancer agents in participants with mature B-cell hematologic malignancies. This master study currently includes 3 substudies and each substudy focusing on a defined population: Substudy 1: Relapsed/refractory (R/R) Chronic lymphocytic leukaemia (CLL)/ Small lymphocytic leukaemia (SLL) Substudy 2: R/R Mantle-cell lymphoma (MCL) Substudy 3: Large B-cell lymphoma (LBCL) or R/R B-cell non-Hodgkin lymphoma (B-NHL) (not applicable to US) The study will have the following sequential periods: 1. Screening period of 28 days 2. Treatment period 3. Follow-up period
