Gocatamig is a new type of immunotherapy that uses a person's immune system to find and destroy cancer cells. Ifinatamab deruxtecan (also known as I-DXd) is a drug which binds to a specific target on cancer cells and delivers treatment to destroy those cells. Durvalumab is a different type of immunotherapy that also destroys cancer cells. Researchers want to know if giving gocatamig, I-DXd, and gocatamig with I-DXd or durvalumab can treat SCLC that did not respond or stopped responding to a prior treatment. The goals of this study are to learn: \* If gocatamig alone, I-DXd alone, and gocatamig with I-DXd or durvalumab are safe and well tolerated \* If people who receive gocatamig alone, I-DXd alone, and gocatamig with I-DXd or durvalumab have their SCLC get smaller or go away Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Short title** A Study to Evaluate the Safety and Efficacy of Gocatamig (MK-6070) and Ifinatamab Deruxtecan (I-DXd) in Participants With Relapsed/Refractory Extensive-Stage Small Cell Lung Cancer (MK-6070-002) Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Official title** A Phase 1b/2 Open-Label Clinical Study to Evaluate the Safety and Efficacy of MK-6070 and Ifinatamab Deruxtecan (I-DXd) in Participants With Relapsed/Refractory Extensive-Stage Small Cell Lung Cancer Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) ## Status and phase **Control arm** Open label Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Registry reports results** No Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Listing at source** Listed Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Recruitment status** Recruiting Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Phase** Phase 1/Phase 2 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Study type** Interventional Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) ## Dates **Completion date** 2029-04-27 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **First posted** 2025-01-17 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Registry last updated** 2026-08-28 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Primary completion date** 2029-04-27 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Start date** 2025-02-27 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) ## Size and sites **Participants** 327 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Participant count basis** Estimated Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Planned participants** 327 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Protocol amendments** 5 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Number of sites** 46 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) ## Sponsor and oversight **Data monitoring committee** No Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Registry sponsor category** Industry Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Lead sponsor** Merck Sharp & Dohme LLC Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Source registry** ClinicalTrials.gov Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) ## Identifiers **Registry ID** NCT06780137 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **ClinicalTrials.gov ID** NCT06780137 Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) **Registry record** Open registry record Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) ## Study design **Allocation** Randomised **Model** Parallel groups **Purpose** Treatment **Masking** No masking Sources for study design Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06780137) ## Outcomes ### Primary outcomes 1.
