Efficacy of IBI-322 with Lenvatinib for Extensive Stage Small Cell Lung Cancer

Real-World Study on the Efficacy of IBI-322 in Combination With Lenvatinib for the Treatment of Extensive Stage Small Cell Lung Cancer and Assessment of Biomarkers

Observational Hunan Province Tumor Hospital · NCT05991180

This study is trying to see how well the combination of IBI-322 and Lenvatinib works for people with extensive-stage small cell lung cancer who haven't had success with their first treatment.

What this trial studies

This observational study aims to collect real-world data on the effectiveness of IBI-322 in combination with Lenvatinib for patients with extensive-stage small cell lung cancer (SCLC). It focuses on patients who have not responded to first-line treatment with PD-(L)1 inhibitors or have progressed after initial responses. The study will gather epidemiological data without intervening in the current medical practices of the participants. By analyzing this data, the study seeks to provide insights into treatment outcomes in a real-world setting.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with extensive-stage SCLC who have not responded to or have progressed after first-line PD-(L)1 inhibitor therapy.

Not a fit: Patients who have not been treated with PD-(L)1 inhibitors or those with early-stage SCLC may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable information on the effectiveness of a new treatment combination for patients with extensive-stage SCLC.

How similar studies have performed: While this approach is observational and builds on existing treatment paradigms, similar studies have shown promise in understanding treatment efficacy in real-world settings.
