Platform Study for the Treatment of Relapsed or Refractory Aggressive Non-Hodgkin's Lymphoma (PRISM Study) (PRISM)

PRISM: A Platform Protocol for the Treatment of Relapsed/Refractory Aggressive Non-Hodgkin's Lymphoma

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).

Study Overview

• Status: Completed
• Conditions: Diffuse Large B Cell Lymphoma; NHL; Non-hodgkin's Lymphoma; DLBCL
• Intervention / Treatment: Drug: AZD9150; Drug: Acalabrutinib; Drug: AZD6738; Drug: Hu5F9-G4; Drug: Rituximab; Drug: AZD5153

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.
