ClinicalTrials ID:NCT03571568

Patient View

This Phase 1/2a trial evaluates BI-1206 with rituximab in relapsed/refractory indolent B-cell NHL. It includes dose escalation and expansion cohorts. Eligible participants are adults with specific NHL subtypes, measurable disease, and prior rituximab treatment. BI-1206 is administered at 375 mg/m2. Participants showing clinical benefit may receive maintenance therapy.

Patient Parameters

Program Overview

Phase 1/2a Clinical Trial of BI-1206, a Monoclonal Antibody to CD32b (FcyRIIB), in Combination with Rituximab with or without Acalabrutinib in Subjects with Indolent B-Cell Non-Hodgkin Lymphoma That has Relapsed or is Refractory to Rituximab

Description

This is a Phase 1/2a, multicenter, dose escalation, consecutive-cohort, open-label trial of BI-1206 in combination with rituximab with or without acalabrutinib in subjects with indolent relapsed or refractory B-cell NHL, sub-types FL (except FL grade 3B), MZL, and MCL.

Phase 2a, consists of signal seeking cohorts followed by a randomized, parallel, two-arm dose optimization.

The trial consists of 2 main parts:

Phase 1

  • Dose Escalation, with two different Arms assessing IV or SC dosing of BI-1206 in combination with rituximab, with dose escalation cohorts and selection of the IV and SC doses of BI-1206 for Phase 2a

Phase 2a

  • Dose Expansion, with one expansion cohort evaluating the selected IV dose of BI-1206 in combination with rituximab
  • Signal Seeking, assessing IV and SC dosing of BI-1206 in combination with rituximab and acalabrutinib. The Signal Seeking will consist of a Safety Run-in and an Expansion
  • Dose Optimization to select the recommended dose of BI-1206 in combination with rituximab and acalabrutinib
