A Phase 3 interventional study of Obrixtamig and Ezabenlimab in Advanced Cancer, sponsored by Boehringer Ingelheim. Not yet recruiting at 15 sites in 6 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-10.
Sponsored by Boehringer Ingelheim · Phase 3, Interventional, and Treatment
This study is open to adults with advanced cancer who received obrixtamig (BI 764532) in one of several previous studies and benefited from treatment. The goal of this study is to find out how well participants who received obrixtamig in a previous study tolerate obrixtamig. Obrixtamig is an antibody-like molecule that may help the immune system fight cancer.
Participants in this study continue receiving obrixtamig and any other study or standard of care anti-cancer medicines they received in their previous study at the same doses and following the same treatment schedule. Treatments are given in 3-week cycles as infusions into a vein.
Participants can stay in the study as long as they benefit from treatment and can tolerate it. During this time, they visit the study site regularly. During the visits, study doctors check participants' health and take note of any unwanted effects.
Boehringer Ingelheim is the lead sponsor of 2,304 studies on the registry; 62 are open to participants now.
Of its 167 completed or terminated interventional studies of FDA-regulated products, 123 (74%) have results posted.
