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)
- Conditions
- Small Cell Lung Cancer
- Interventions
- Biological: Ifinatamab Deruxtecan (I-DXd)
- Registration Number
- NCT06780137
- Lead Sponsor
- Merck Sharp & Dohme LLC
- Brief Summary
Researchers are looking for new ways to treat people with extensive-stage small cell lung cancer (SCLC) that has relapsed or is refractory. 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. Researchers want to know if giving gocatamig and/or I-DXd can treat SCLC that did not respond or stopped responding to a prior treatment.
The goals of this study are to learn:
* If gocatamig and I-DXd are safe and well tolerated
* If people who receive gocatamig and I-DXd have their SCLC get smaller or go away
- Detailed Description
This study will consist of two parts. Part 1 will assess the safety, tolerability, and efficacy of gocatamig and I-DXd at dosing intervals of once every 2 weeks (Q2W) and/or once every 3 weeks (Q3W) at doses determined in study MK-6070-001 (NCT: NCT04471727). Part 2 will assess the safety and tolerability of gocatamig in Japanese participants.
