Phase 1/2a Clinical Trial of BI-1206, a Monoclonal Antibody to CD32b (FcγRIIB), in Combination with Pembrolizumab in Subjects with Advanced Solid Tumors
EU CTIS ID: 2023-509846-36-00
What this study is testing
The primary objectives/endpoints of this trial are to: 1. Assess the safety and tolerability profile of increasing doses of BI-1206, administered intravenously (IV) or subcutaneously (SC), in combination with pembrolizumab in subjects with advanced solid tumors. Phase 1: 2. Identify dose-limiting toxicities (DLTs), determine the maximum tolerated dose (MTD) and select a signal-seeking Phase 2a dose of BI-1206, given via IV infusion or SC injection in combination with pembrolizumab (administered at the standard dose of 200 mg every 3 weeks) to subjects with advanced solid tumors who are experiencing disease progression and have been previously treated with anti-PD1 or PDL1 antibodies. Phase 2a: Select a recommended Phase 2 dose (RP2D) of BI-1206 given via SC injection in combination with pembrolizumab to subjects with non-small cell lung cancer (NSCLC) and uveal melanoma. Document the frequency and occurrence of adverse events (AEs), treatment-emergent adverse events (TEAEs), and immune-related AEs (irAEs).

Who can take part
You may be able to join if
- For Phase 1: Is willing and able to provide written informed consent for the trial.
- Has at least 1 measurable disease lesion as defined by the Response Evaluation Criteria in Solid Tumors (RECIST).
- Is willing to provide an archival tumor tissue sample or newly obtained [core, incisional, OR excisional] biopsy of a tumor lesion not previously irradiated. If the Investigator considers that a tissue biopsy is not safe and/or not technically feasible, then the subject will not be required to undergo the biopsy. a. The Screening biopsy must be performed prior to the first dose of BI-1206 (on non-previously irradiated lesions only), and at least 4 weeks after the last dose of tumor-directed therapy. The biopsy at Screening can be replaced with a formalin- fixed archival tumor tissue sample collected from a previous standard of care biopsy, provided that the biopsy was performed after the subject's last tumor- directed therapy and prior to study entry. Subjects who do not have an archival tissue sample at Screening may still be enrolled in the study.
- Has a life expectancy of ≥12 weeks.
- Participants who are HBsAg positive are eligible if they have received HBV antiviral therapy for at least 4 weeks and have undetectable HBV viral load prior to enrollment.
- Participants with history of HCV infection are eligible if HCV viral load is undetectable at Screening.
You likely can't join if
- Needs doses of prednisolone >10 mg daily (or equipotent doses of other corticosteroids) while on the trial other than as premedication. During the Screening period, doses of up to 20 mg/day may be given but the dose must be reduced to 10 mg/day within 7 days prior to the first dose of study drug. Steroids are allowed as premedication in subjects with allergies to contrast scans.
- Has received a live vaccine within 30 days before the first dose of study treatment. COVID-19 vaccines based on viral RNA or protein fragments, or killed viruses, are allowed. COVID 19 vaccines based on live replicating viral or bacterial vectors are not allowed.
- Has uncontrolled or significant cardiovascular disease as per protocol definition.
- Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated CNS metastases may participate provided they are radiologically stable (without evidence of progression for at least 4 weeks by repeat imaging [performed during Screening]); have no newly-onset or worsening symptomatology of brain metastases; and have not required steroids for at least 14 days before study treatment.
- Has a known psychiatric or substance abuse disorder that would interfere with the subject's ability to cooperate with the requirements of the study.
- Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or lead to participation not being in the best interest of the subject, in the opinion of the Investigator.
