Trilaciclib compared to placebo for patients with extensive stage small cell lung cancer receiving topotecan

A Randomized, Double-Blind, Placebo-Controlled Study of Trilaciclib vs Placebo in Patients With Extensive Stage Small Cell Lung Cancer (ES-SCLC) Receiving Topotecan Chemotherapy

Phase 4 Interventional Pharmacosmos A/S · NCT05874401

This study is testing if a new drug called trilaciclib can help people with advanced small cell lung cancer live longer and feel better while they receive chemotherapy.

What this trial studies

This multicenter, randomized, double-blind, placebo-controlled study aims to evaluate the effectiveness of trilaciclib in improving overall survival in patients with extensive-stage small cell lung cancer (ES-SCLC) who are receiving topotecan. Participants will be randomly assigned to receive either trilaciclib or a placebo before their chemotherapy treatment. The study includes three phases: screening, treatment, and survival follow-up, with patients monitored until disease progression or other specified endpoints. The goal is to determine if trilaciclib can reduce chemotherapy-induced myelosuppression and improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults with confirmed extensive-stage small cell lung cancer who have experienced disease progression after prior chemotherapy.

Not a fit: Patients with a history of treatment with topotecan or trilaciclib, or those with certain severe health conditions, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option that enhances survival rates for patients with ES-SCLC undergoing chemotherapy.

How similar studies have performed: Previous studies have shown promising results with trilaciclib in reducing chemotherapy-induced myelosuppression, making this approach a continuation of established research.
