Phase 2/3RecruitingCanadian Cancer Trials GroupNCT04093167Data as of May 2026

Treatment: PembrolizumabThe standard or usual treatment for this disease is pembrolizumab given by needle into the veins (IV). Some cancers shed DNA (circulating tumour DNA or ctDNA) or genes (biomarkers) into the blood, and levels of these biomarkers may be able to tell researchers how people respond to treatment with pembrolizumab before they feel worse, or the cancer is worse on imaging tests. Researchers are studying how levels of these biomarkers can show how cancers are responding to treatment and whether adding chemotherapy to pembrolizumab based on detection of ctDNA can offer better results.

Extracted eligibility criteria

Cancer type

Non-Small Cell Lung Carcinoma

Biomarker criteria

Required: EGFR wild-type

Confirmed EGFR and ALK mutation-negative disease based on testing consistent with local guidelines.

Required: ALK wild-type

Confirmed EGFR and ALK mutation-negative disease based on testing consistent with local guidelines.

Required: PD-L1 (CD274) TPS ≥ 50% (Tumour Proportion Score (TPS) ≥ 50%)

Patients must have a PD-L1 test result from a certified laboratory indicating PD-L1 expression Tumour Proportion Score (TPS) ≥ 50%. Patients with lower PD-L1 TPS scores treated with single agent pembrolizumab consistent with local guidelines and regulatory approvals may be eligible following discussion with CCTG.

Disease stage

Required: Stage IV, III

Metastatic disease required

Histologically or cytologically confirmed metastatic NSCLC. Patients with stage III disease are eligible if they are not candidates for surgical resection or definitive chemoradiation.

Performance status

ECOG 0–2(Ambulatory, capable of self-care)

Prior therapy

Cannot have received: concurrent anti-cancer therapy or investigational anti-cancer agents

Concurrent treatment with other anti-cancer therapy or other investigational anti-cancer agents

Lab requirements

Blood counts

White Blood Cells ≥ 2.0 x 10^9/L (2000/μL); Absolute neutrophils ≥ 1.5 x 10^9/L (1500/μL); Platelets ≥ 100 x 10^9/L (100 x 10^3/μL)

Kidney function

Serum creatinine or Creatinine clearance ≤ 1.5 x ULN OR ≥ 40 mL/min

Liver function

Bilirubin ≤ 1.5 x ULN; AST and/or ALT ≤ 3 x ULN, < 5 x ULN for patients with liver metastases

Adequate hematology and organ function to continue immunotherapy or receive standard platinum combination therapy (must be done prior to registration for ctDNA testing) and prior to enrollment and randomization).
