No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT06780137). This is a study registration, not published results. Lead sponsor: Merck Sharp & Dohme LLC. Recruitment status: RECRUITING. Phase: PHASE1, PHASE2. Study type: INTERVENTIONAL. Enrollment: 327 participants (ESTIMATED). Conditions: Small Cell Lung Cancer. Interventions: BIOLOGICAL: Gocatamig; BIOLOGICAL: Ifinatamab Deruxtecan (I-DXd); BIOLOGICAL: Durvalumab. Primary outcome measures: Number of Participants Who Experience an Adverse Event (AE) , Up to approximately 44 months; Number of Participants Who Experience One or More Dose-Limiting Toxicities (DLTs) , Up to approximately 3 weeks; Number of Participants Who Discontinue Study Intervention Due to an AE , Up to approximately 44 months; Part 1: Objective Response Rate (ORR) , Up to approximately 44 months. 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. 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
