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
