Study of Copanlisib in Combination With Standard Immunochemotherapy in Relapsed Indolent Non-Hodgkin's Lymphoma (iNHL) — CHRONOS-4  

Lymphoma, Non-Hodgkin Clinical Trial

Official title: A Phase III, Randomized, Double-blind, Controlled Multicenter Study of Intravenous PI3K Inhibitor Copanlisib in Combination With Standard Immunochemotherapy Versus Standard Immunochemotherapy in Patients With Relapsed Indolent Non-Hodgkin's Lymphoma (iNHL)

Status Terminated

Clinical Trial Summary

The purpose of this study is to assess whether copanlisib in combination with standard immunochemotherapy (rituximab in combination with bendamustine [R-B] and rituximab in combination with a 4 drug combination of cyclophosphamide, doxorubicin, vincristine and prednisone/prednisolone [R-CHOP]) is effective and safe, compared with placebo in combination with standard immunochemotherapy (R-B or R-CHOP) in patients with relapsed iNHL who have received at least one, but at most three, lines of treatment, including rituximab-based immunochemotherapy and alkylating agents.

Clinical Trial Description

Patients should be in need of and fit for immunochemotherapy and should not be resistant to rituximab (resistance defined as lack of response or progression within 6 months of the last date of rituximab administration, including rituximab, and/or rituximab biosimilars, and/or anti-CD20 monoclonal antibody).

This study will be composed of two parts: Safety run-in and phase III part. The purpose of the safety run-in part of this study is to assess whether the drug being tested (copanlisib) in combination with standard immunochemotherapy (R-B or R-CHOP) is safe and at what dose level of the study drug (copanlisib - 45mg or 60 mg) patients are able to tolerate the study treatment combination. In addition to finding a safe and tolerable dose level for the phase III part of the study, efficacy will also be evaluated for patients that stay on the study treatment during the safety run-in. The phase III part of the study started with the determined recommended dose of copanlisib of 60 mg in combination with R-B. Combination treatment of copanlisib at the recommended/approved dose of 60 mg with R-B or R-CHOP was completed in April 2021.

A maximum of 24 patients will take part in the safety run-in part of this study. In the phase III part approximately 520 patients will be randomly assigned to blinded treatment arms of copanlisib plus R-B or R-CHOP or placebo plus R-B or R-CHOP. Combination therapy (copanlisib/placebo with R-B or R-CHOP) will be administered for a maximum of 6 cycles (C1-C6). Copanlisib/placebo (study drug) monotherapy will be administered from C7 onwards. ;
