Triple threat before surgery: could this combo shrink lung tumors better?
NCT ID NCT06877299
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial is testing whether giving a combination of low-dose radiation, stereotactic body radiotherapy (SBRT), the immunotherapy drug tislelizumab, and standard chemotherapy before surgery can improve outcomes for people with stage II to III non-small cell lung cancer. The study will enroll 30 participants whose tumors are considered removable. The main goal is to see how many patients have no cancer cells left in their surgical samples (pathologic complete response).
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tislelizumab (immunotherapy) plus platinum-based chemotherapy, combined with low-dose radiation and stereotactic body radiotherapy (SBRT)
- What this could lead to
- If successful, this approach could shrink tumors before surgery, potentially improving survival and reducing recurrence in people with resectable non-small cell lung cancer.
- What could go wrong
- This is a small, early-phase (phase 2) study with only 30 participants, so results may not apply to everyone. The combination of radiation, immunotherapy, and chemotherapy also carries risks of serious side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age ≥ 18 and ≤ 75 years; 2. Patients with untreated stage IIA-IIIB non-small cell lung cancer, diagnosed cytologically or histologically (according to the AJCC 9th edition of thoracic tumor staging); 3. Pulmonary lesions will be assessed as resectable or potentially resectable by a multidisciplinary team, including a thoracic surgeon; 4. At least one imaging-measurable lesion according to the Response Evaluation Criteria in Solid Tumors (RECIST v1.1); 5. Ability to provide tumor tissue or cell wax blocks that meet quality control standards for PD-L1 expression testing. Exclusion Criteria: 1. The pathology is small cell lung cancer (SCLC), including lung cancer mixed with SCLC and non-small cell lung cancer (NSCLC); 2. Patients with known EGFR-sensitive mutations or ALK fusion. 3. Previously received the following therapies: anti-PD-1, anti-PD-L1 or anti-PD-L2 drugs or another drug that stimulates or synergistically inhibits T cell receptors; 4. Subjects with any known or suspected autoimmune disorder or immunodeficiency, with the following exceptions: hypothyroidism, hormone therapy is not needed, or well controlled at physiological dose; controlled type I diabetes; 5. Active infection requiring systemic treatment.
