DAREON ® -Lung-1: A Study in People With Advanced Small Cell Lung Cancer to Compare Obrixtamig Plus Atezolizumab, Carboplatin, and Etoposide Treatment With Standard Chemoimmunotherapy (NCT07472517)

DAREON ® -Lung-1: A Phase III Multi-center, Open-label, Randomised Trial of Intravenous Obrixtamig in Combination With Atezolizumab, Carboplatin, and Etoposide vs. Atezolizumab, Carboplatin, and Etoposide as First-line Treatment in Patients With Extensive-stage Small Cell Lung Cancer

🟢 Recruiting Phase3 💊 Investigational Drug / Biologic Sponsor: Boehringer Ingelheim

🩺 Plain-English Summary (8th-Grade Level)

This study is open to adults with advanced small cell lung cancer (SCLC). The purpose of this study is to find out if a study medicine called obrixtamig plus standard treatment (atezolizumab, carboplatin, and etoposide) improves survival when compared to standard treatment alone. Obrixtamig is an antibody-like molecule that may help the immune system fight cancer. Another purpose of the study is to test a medical device being developed to measure levels of the tumour marker DLL3. Participants are put into 2 groups randomly, which means by chance. One group receives obrixtamig and standard treatment. The other group receives standard treatment without obrixtamig. All treatments are given as infusions into a vein. Participants are in the study for up to 3 years. During this time, they visit the study site regularly. Participants in the group receiving obrixtamig stay overnight at the study site following the first 2 obrixtamig treatments. At the visits, doctors check the size of the tumour(s). The results are compared between the 2 groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.
