Thymosin α-1's effect on treatment for advanced lung cancer

A Prospective Phase II Controlled Study to Evaluate the Impact of Thymosin Alpha 1 on the Completion Rate of Consolidation Immunotherapy After Radical Radiochemotherapy for Locally Advanced Non-Small Cell Lung Cancer

Phase 2 Interventional Sun Yat-sen University · NCT06139419

This study is testing whether adding thymosin alpha-1 to standard treatment can help people with advanced lung cancer live longer and respond better to their therapy.

What this trial studies

This phase II randomized study investigates the impact of thymosin alpha-1 on the efficacy of concurrent chemoradiotherapy followed by immunotherapy consolidation in patients with locally advanced non-small cell lung cancer (NSCLC). Participants will be randomly assigned to receive either thymosin alpha-1 alongside their treatment or standard care without it. The study aims to evaluate survival outcomes, treatment responses, and any associated toxicities. By comparing these two groups, researchers hope to determine the potential benefits of thymosin alpha-1 in enhancing treatment effectiveness.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with histologically confirmed locally advanced and unresectable NSCLC who have not received prior radiotherapy or surgery.

Not a fit: Patients with active autoimmune diseases, prior small-cell lung carcinoma, or those requiring immunosuppressive therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve survival rates and treatment responses for patients with locally advanced NSCLC.

How similar studies have performed: While the use of thymosin alpha-1 in this context is relatively novel, similar studies have shown promise in enhancing treatment outcomes for cancer patients.
