NCT ID NCT05765825

First seen Apr 30, 2026 · Last updated Jun 19, 2026 · Updated 11 times

Summary

This phase 2 trial is testing a new approach for people with extensive-stage small cell lung cancer who have not had prior treatment. It combines low-dose radiation with standard chemotherapy (cisplatin or carboplatin plus etoposide) and the immunotherapy drug serplulimab. The goal is to see if this combination can delay cancer progression and improve survival. The study enrolled 61 participants across multiple centers.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

serplulimab (an immunotherapy drug), cisplatin or carboplatin (chemotherapy), etoposide (chemotherapy), and low-dose radiotherapy

What this could lead to

If this works, it could point toward a more effective first-line treatment for extensive-stage small cell lung cancer, potentially improving how long people live without their cancer getting worse.

What could go wrong

This is a small, early-phase (phase 2) study with no comparison group, so results are uncertain. The combination of treatments may cause significant side effects, and it is not yet known if it will be better than standard care.
