Long-term outcomes after first-line tislelizumab plus chemotherapy in advanced squamous NSCLC

Long-Term Efficacy and Safety Analysis of First-Line Tislelizumab in Patients With Advanced Squamous NSCLC: a Retrospective Real-World Study Based on RATIONALE-307

Observational Cancer Institute and Hospital, Chinese Academy of Medical Sciences · NCT07478809

This project collects long-term survival data from people with advanced squamous non-small cell lung cancer who received first-line tislelizumab plus chemotherapy in RATIONALE-307 to see who benefited most.

What this trial studies

This retrospective observational effort gathers extended follow-up and survival information on participants in the RATIONALE-307 trial who received first-line tislelizumab plus chemotherapy. Investigators will use medical records and registry data to capture overall survival, duration of response, and other long-term outcomes beyond the original trial period. Analyses will search for clinical and demographic factors associated with greater durable benefit and may include subgroup comparisons. No new treatments are given; the project aims to enrich real-world evidence on long-term immunotherapy effectiveness in squamous NSCLC.

Who should consider this trial

Good fit: Ideal candidates are people with advanced squamous NSCLC who participated in the RATIONALE-307 trial and were alive at the end of that trial's follow-up period.

Not a fit: Patients who did not enroll in RATIONALE-307, who have non-squamous NSCLC, or who had a documented death before RATIONALE-307 completion are not eligible and would not directly benefit from this retrospective analysis.

Why it matters

Potential benefit: If successful, the findings could help identify which patients with squamous NSCLC are most likely to experience long-term survival after first-line tislelizumab plus chemotherapy.

How similar studies have performed: Other trials of PD-1/PD-L1 immunotherapies in advanced NSCLC have shown durable responses and long-term survival in subsets of patients, though long-term real-world data specific to tislelizumab in squamous NSCLC remain limited.
