Triple immunotherapy cocktail shows promise against tough cancers
NCT ID NCT03744468
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested combinations of three immunotherapy drugs—tislelizumab, surzebiclimab, and alcestobart—in 147 adults with advanced solid tumors that had not responded to prior treatments. The goal was to find safe doses and see if the drugs could shrink tumors. The trial is now complete, and results will help guide future research on these combinations.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tislelizumab, surzebiclimab, and alcestobart (three immunotherapy drugs that help the immune system attack cancer)
- What this could lead to
- If successful, this combination could offer a new treatment option for people with advanced solid tumors that have not responded to standard therapies.
- What could go wrong
- This is an early-phase trial (Phase 1/2) with a small number of participants, so results may not apply to all patients. Side effects from immunotherapy can be serious, including immune-related inflammation in healthy organs.

Key Inclusion Criteria: * Participants were aged \>=18 years. * Adequate organ function. * Eastern Cooperative Oncology Group (ECOG) performance status \<=1. * Must have been able to provide a recently obtained archival tumor tissue or fresh tumor biopsy. * The phase 1 dose escalation and phase 2 safety lead-in enrolled participants with histologically/cytologically confirmed advanced/metastatic solid tumors who had previously received standard systemic therapy per local guidelines, unless it was not available, not tolerated or determined not appropriate based on investigators judgement, and had at least 1 evaluable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. * The phase 2 dose expansion enrolled participants with recurrent/metastatic HNSCC (Cohorts 1 and 4) and advanced/metastatic NSCLC (Cohorts 2 and 5), with disease progression that occurred \>=10 weeks from the initiation of anti-PD-1/PD-L1 treatment for locally advanced or metastatic disease and had at least 1 measurable lesion outside of the central nervous system per RECIST v1.1. Key Exclusion Criteria: * A history of severe hypersensitivity reactions to other monoclonal antibodies. * Active autoimmune disease or a history of autoimmune diseases that might relapse or a history of life-threatening toxicity related to prior immune therapy. * Any condition that required systemic treatment with either corticosteroids or other immunosuppressive medication \<=14 days before administration of study drug. * A history of interstitial lung disease, noninfectious pneumonitis or uncontrolled lung diseases. * Prior therapy targeting TIM-3 and/or LAG-3. * The phase 2 dose expansion NSCLC cohorts excluded participants with known sensitizing epidermal growth factor receptor (EGFR) mutation, v-raf murine sarcoma viral oncogene homolog B1 (BRAF) mutation, anaplastic lymphoma kinase (ALK) fusion, or c-ros oncogene 1 (ROS1) fusion.
