A Study of AZD0486 Monotherapy or in Combination With Other Anti-Cancer Agents for Mature B-Cell Malignancies

Официальное название

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

Обзор

The purpose of this study is to assess the safety and efficacy of surovatamig (formerly AZD0486) administered as monotherapy or in combination with other anticancer agents in participants with hematological malignancies

Подробное описание

This is open-label, multi-center study to evaluate the safety and preliminary efficacy of surovatamig 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 lymphoma (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
