Study Details

Study Description

Brief Summary

This is a Phase 1 platform protocol designed to evaluate various targeted agents for the treatment of relapsed/refractory aggressive Non-Hodgkin's Lymphoma (NHL).

Condition or Disease	Intervention/Treatment	Phase
NHL DLBCL Non-hodgkin's Lymphoma Diffuse Large B Cell Lymphoma	Drug: AZD9150 Drug: Acalabrutinib Drug: AZD6738 Drug: Hu5F9-G4 Drug: Rituximab Drug: AZD5153	Phase 1

Detailed Description

This is a Phase 1 platform protocol designed to evaluate various targeted agents for the treatment of relapsed/refractory aggressive Non-Hodgkin's lymphoma (NHL). Each study arm will be conducted in a predefined disease subset. All study arms are open label and allocation to each study arm will not be randomized.

As this master platform protocol has multiple study arms, subjects can be screened for several study arms at once. Likewise, a subject who ends participation in one study arm may be rescreened for participation in another (separate) study arm.

The primary objective of the study is to evaluate the safety of targeted agents for the treatment of relapsed/refractory aggressive Non-Hodgkin's Lymphoma (NHL). This protocol has a modular design, with the potential for future treatment arms to be added via protocol amendment.

Outcome Measures

Primary Outcome Measures

Safety of the study treatments when given in combination [Incidence of adverse events] [Through to study completion, an average of 1 year]
Incidence of adverse events

Secondary Outcome Measures

Assessment of the efficacy of each treatment by evaluation of overall response rate using RECIL 2017 response criteria [Through to study completion, an average of 1 year]
The overall response rate (ORR) is defined as the rate of subjects who achieve either a partial response (PR) or complete response (CR) as assessed by investigators before receiving any other anticancer therapy.
Duration of response (DOR) using RECIL 2017 response criteria for the anti-tumour activity of each therapy. [Through to study completion, an average of 1 year]
Duration of Response (DOR) is defined as the time from the first objective response of CR or PR to the time of documented disease progression or death due to any cause, whichever occurs first.
Progression free survival (PFS) using RECIL 2017 response criteria for the anti-tumour activity of each therapy. [Through to study completion, an average of 1 year]
Progression free survival (PFS) is defined as the time from first dose date to documented objective disease progression, or death from any cause, whichever occurs first. Disease progression will be determined by the investigators per standard response criteria as outlined in each respective study arm.
Overall Survival (OS) [From the beginning of treatment until the date of death from any cause, assessed up to 12 months]
Overall Survival (OS) is defined as the time from first dose until the date of death from any cause.
