Testing different doses of BI 764532 for advanced small cell lung cancer

DAREONᵀᴹ-8: A Phase I, Open-label, Dose Escalation and Expansion Trial of Repeated Intravenous Infusions of BI 764532 Combined With Standard of Care (Platinium, Etoposide, and Anti-PD-L1) in Patients With Extensive-stage Small Cell Lung Carcinoma

Phase 1 Interventional Boehringer Ingelheim · NCT06077500

This study is testing different doses of a new drug called BI 764532 to see if it can help adults with advanced small cell lung cancer when used with standard treatments like chemotherapy.

What this trial studies

This study is designed for adults with extensive stage small cell lung cancer who are eligible for standard treatments like chemotherapy and anti-PD-L1 immunotherapy. The main goal is to determine the highest tolerable dose of BI 764532 when combined with standard care. Participants will receive infusions of BI 764532 along with other treatments, and their health will be monitored through regular visits to the study site. The study aims to assess both the safety and efficacy of the treatment regimen over the duration of the trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with confirmed extensive-stage small cell lung carcinoma who have not received prior systemic treatment.

Not a fit: Patients with limited-stage small cell lung cancer or those who have previously undergone systemic treatment for extensive-stage disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes for patients with advanced small cell lung cancer.

How similar studies have performed: Other studies have shown promise with similar immunotherapy approaches, but this specific combination is being evaluated for the first time.
