New combo attack on lung cancer: adding radiation to immunotherapy and chemo
NCT ID NCT03774732
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 3 trial tests whether adding radiation to the standard combination of pembrolizumab (an immunotherapy) and chemotherapy can improve survival in people with advanced non-small cell lung cancer. About 327 participants with stage IIIB/IV disease will receive either the triple therapy or standard care. The goal is to see if radiation boosts the immune response against tumors outside the radiation field.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pembrolizumab (a drug that helps the immune system fight cancer) combined with chemotherapy (carboplatin, paclitaxel, nab-paclitaxel, cisplatin, or pemetrexed) and radiation therapy
- What this could lead to
- If successful, this combination could extend survival for people with advanced lung cancer beyond current standard treatments.
- What could go wrong
- This is a Phase 3 trial, but the added radiation may increase side effects without improving outcomes. Results may not apply to all lung cancer types.

INCLUSION CRITERIA: 1. Patient must have signed a written informed consent form prior to any study specific procedures 2. Histologically or cytologically confirmed advanced (stage IIIB/IIIC/IV), squamous or non-squamous NSCLC 3. NSCLC patients eligible for treatment with pembrolizumab and chemotherapy according to the European Marketing Authorization: 1. squamous: in combination with carboplatin and either paclitaxel or nab-paclitaxel 2. non squamous with no EGFR or ALK positive mutations: in combination with pemetrexed and a platinum based chemotherapy 4. Patient ≥18 of age 5. Eastern Cooperative Oncology Group (ECOG) performance status 0 - 1 6. Life expectancy \>3 months 7. Measurable lesion as assessed by RECIST version 1.1 8.

Patients must have adequate organ function defined by the following laboratory results obtained within 14 days prior to the first study treatment: 1. absolute neutrophil count of ≥1 500 /mm³ 2. platelets ≥ 100 000/mm³ 3. haemoglobin \>9 g/dL (transfusions allowed) 4. creatinine clearance \>60 mL/min 5. bilirubin ≤1.5 X upper limit of normal (ULN) (unless Gilbert's syndrome where 3 X ULN is permitted) 6. serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 X ULN (unless documented liver metastasis where ≤5 X ULN is permitted) 7. Alkaline phosphatase (ALP) ≤2.5 X ULN (unless documented bone or liver metastasis where ≤5 X ULN is permitted) 8. International normalized ratio (INR), prothrombin (PT), and prothrombin time (PTT) ≤1.5 X ULN (unless the subject is receiving anticoagulant therapy) 10.
