Chidamide plus PD-L1 inhibitor with carboplatin and etoposide for first-line extensive-stage small‑cell lung cancer

Official title: A Prospective, Single-Arm, Single-Center Phase II Study Evaluating the Efficacy and Safety of Chidamide Tablets Combined With PD-L1 Inhibitor, Carboplatin, and Etoposide as First-Line Treatment in Patients With Extensive-Stage Small-Cell Lung Cancer (ES-SCLC)

Run by China Medical University, China · NCT07373964 · Data updated 2026-11-12

This trial will test whether adding chidamide to a PD-L1 inhibitor together with carboplatin and etoposide helps people with extensive-stage small‑cell lung cancer stay progression‑free longer.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults (18–75) with histologically confirmed extensive‑stage SCLC, no prior systemic therapy for ES‑SCLC, ECOG performance status 0–1, measurable disease, and adequate organ function.

Probably not a fit

Patients who previously received HDAC inhibitors or immune checkpoint inhibitors, those with poor performance status, active uncontrolled infections or severe organ dysfunction, or recent other malignancies are unlikely to benefit or be eligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a single-center, single‑arm Phase II study enrolling about 36 patients with previously untreated extensive‑stage small‑cell lung cancer. Participants receive four cycles of induction therapy combining oral chidamide with a PD‑L1 inhibitor, carboplatin, and etoposide, followed by chidamide maintenance until disease progression or unacceptable toxicity. The primary endpoint is progression‑free survival measured by RECIST v1.1, and secondary endpoints include objective response rate, disease control rate, duration of response, overall survival, and safety. Eligible patients must be 18–75 years old with ECOG 0–1, measurable disease, and adequate organ function.

Why it matters

Potential benefit: If successful, the combination could prolong time without disease progression and potentially improve overall survival as a new first‑line option for ES‑SCLC.

How similar studies have gone: PD‑L1 inhibitors combined with platinum‑etoposide have improved outcomes in ES‑SCLC, but adding an HDAC inhibitor like chidamide is largely investigational and has limited prior clinical evidence.
