Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with relapsed or refractory indolent B-cell non-Hodgkin lymphoma who have previously received at least one rituximab-based therapy.

Probably not a fit

Patients who have had an allogenic bone marrow or stem cell transplant within the last 12 months or have active chronic graft versus host disease may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the safety and efficacy of BI-1206, a monoclonal antibody, in combination with rituximab, with or without acalabrutinib, for patients with indolent B-cell non-Hodgkin lymphoma that has relapsed or is refractory to previous treatments. The trial is divided into two phases: Phase 1 focuses on dose escalation to determine the optimal dosing of BI-1206, while Phase 2a includes dose expansion and optimization based on the findings from Phase 1. Participants will be monitored for treatment response and safety throughout the trial.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat indolent B-cell non-Hodgkin lymphoma.

How similar studies have gone: Other studies have shown promise with similar combination therapies in treating B-cell non-Hodgkin lymphoma, indicating potential for success in this approach.
