Phase 1/2a Clinical Trial of BI-1206, a Monoclonal Antibody to CD32b (FcyRIIB), in Combination with Rituximab in Subjects with Indolent B-Cell Non-Hodgkin Lymphoma That has Relapsed or is Refractory to Rituximab

Full description

This is a Phase 1/2a, dose escalation, consecutive-cohort, open-label trial of BI-1206 in combination with rituximab in subjects with indolent relapsed or refractory B-cell NHL, subtypes FL (except FL grade 3B), MZL, and MCL. The trial consists of 2 main parts: Phase 1 with two different Arms assessing IV or SC dosing of BI-1206,with dose escalation cohorts and selection of the RP2D of IV dosing (ivRP2D)and the RP2D of SC dosing (scRP2D) of BI-1206 in combination with rituximab (administered IV). Phase 2a with two expansion cohorts evaluating the ivRP2D and scRP2D of BI-1206 in combination with rituximab (administered IV). Subjects in each phase (Phase 1 and 2a) and dosing Arms will receive 1 cycle of induction therapy with BI-1206 in combination with rituximab. Subjects who show clinical benefit (complete response [CR], partial response [PR], or stable disease [SD]) at Week 6 will continue onto maintenance therapy and receive BI-1206 ( using the same dose and route of administration as induction therapy) and rituximab once every 8 weeks (relative to previous maintenance dose) for up to 6 maintenance cycles, or up to 1 year from first dose of BI-1206 (whichever occurs first).
