New drug combo targets Hard-to-Treat cancers in early trial
NCT ID NCT05981703
First seen Jun 24, 2026 · Last updated Sep 15, 2026 · Updated 5 times
Summary
This early-phase study is testing a new drug called BGB-26808, either alone or with another drug (tislelizumab), in people with advanced solid tumors that have not responded to standard treatments. The main goal is to find a safe dose and check for side effects. About 217 participants will take part across multiple centers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BGB-26808 (HPK1 inhibitor) and tislelizumab (anti-PD-1 antibody)
- What this could lead to
- If successful, this could lead to a new treatment option for people with advanced solid tumors that have stopped responding to other therapies.
- What could go wrong
- This is an early Phase 1 trial focused on safety and dosing, so it is too soon to know if the drug will work. Side effects are possible, and the drug may not shrink tumors.

Inclusion Criteria: 1. Able to provide a signed and dated written informed consent prior to any study-specific procedures, sampling, or data collection. 2. Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 1. 3. Phase 1a: Participants with histologically or cytologically confirmed advanced, metastatic, and unresectable solid tumors that are immune-sensitive who have previously received standard systemic therapy, or for whom treatment is not available or not tolerated, or for whom treatment is determined not appropriate based on investigator's judgment and who have not received prior therapy targeting hematopoietic progenitor kinase 1 (HPK1). 4. Phase 1b: Participants with histologically confirmed locally advanced unresectable or metastatic tumor types and who have not had prior systemic treatment. Participants who received prior systemic therapy in a neo-adjuvant or adjuvant setting with curative intent for nonmetastatic disease must have experienced a disease-free interval of ≥ 6 months from the last dose of systemic therapy prior to the first dose of study treatments. 5. ≥ 1 measurable lesion per RECIST v1.1. 6. Able to provide an archived tumor tissue sample. 7. Adequate organ function. 8. Females of childbearing potential must be willing to use a highly effective method of birth control for the duration of the study, and for ≥ 90 days after the last dose of BGB-26808, or for ≥ 120 days after the last dose of tislelizumab, or for up to ≥ 270 days after the last dose of chemotherapy. 9. Nonsterile males must be willing to use a highly effective method of birth control for the duration of the study treatment period and for ≥ 90 days after the last dose of BGB-26808, or for ≥ 120 days after the last dose of tislelizumab, or for ≥ 180 days after the last dose of chemotherapy. Exclusion Criteria: 1. Prior treatment with anti-PD-1, anti-PD-L1, anti-PD-L2, anti-TIGIT, anti-CTLA4, or any other antibody or drug specifically targeting T-cell costimulation or checkpoint pathways. 2. Uncontrollable pleural effusion, pericardial effusion, or ascites requiring frequent drainage or medical intervention. 3. Clinically significant bleeding from the gastrointestinal tract within 28 days before the first dose of study treatment(s). 4. Active leptomeningeal disease or uncontrolled, untreated brain metastasis. 5. Active autoimmune diseases or history of autoimmune diseases that may relapse 6. Any malignancy ≤ 3 years before the first dose of study treatment(s) except for the specific cancer under investigation in this study and any locally recurring cancer that has been treated with curative intent (eg, resected basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the cervix or breast). 7. Any condition that required systemic treatment with either corticosteroids (\> 10 mg daily of prednisone or equivalent) or other immunosuppressive medication ≤ 14 days before the first dose of study treatment(s). 8. History of interstitial lung disease, noninfectious pneumonitis, or uncontrolled lung diseases including pulmonary fibrosis, acute lung diseases. 9. Uncontrolled diabetes. 10. Infection (including tuberculosis infection) requiring systemic (oral or intravenous) antibacterial, antifungal, or antiviral therapy ≤ 14 days before the first dose of study treatment(s). Note: Other protocol defined Inclusion/Exclusion criteria may apply.
