Researchers are investigating advanced small cell lung cancer SCLC in adults to determine if adding a medicine called obrixtamig to the standard treatment of atezolizumab, carboplatin, and etoposide improves survival compared to the standard treatment alone. Obrixtamig is a molecule designed to help the immune system fight cancer. The study also tests a new medical device that measures levels of the tumour marker DLL3. This is a phase III clinical trial sponsored by Boehringer Ingelheim, using a randomized design to compare treatments. Participants are randomly assigned to one of two groups. One group receives obrixtamig together with the standard treatment, while the other group receives only the standard treatment. All treatments are given through infusions into a vein. Participants receiving obrixtamig will stay overnight at the study site after their first two treatments. The study lasts up to three years, during which tumour size and health status are regularly checked. Throughout the study, participants visit the study site regularly for assessments. Doctors monitor tumour response and check for any side effects or unwanted reactions. The main outcome is overall survival measured up to 36 months. Additional outcomes include progression-free survival, symptom changes, response rates, and monitoring of treatment-related side effects. The study team closely tracks participant health and evaluates quality of life using questionnaires during the first year.
