Phase 1B2 Study to Assess Safety and Effectiveness of Ifinatamab Deruxtecan I-DXd in Adults With Recurrent or Metastatic Solid Tumors

What this Trial Is About

Researchers are evaluating the efficacy and safety of ifinatamab deruxtecan I-DXd in adults with various recurrent or metastatic solid tumors. These tumor types include endometrial cancer, head and neck squamous cell carcinoma, pancreatic ductal adenocarcinoma, colorectal cancer, hepatocellular carcinoma, adenocarcinoma of the esophagus, gastroesophageal junction and stomach, urothelial carcinoma, ovarian cancer, cervical cancer, biliary tract cancer, HER2-low and HER2 IHC 0 breast cancer, cutaneous melanoma, and neuroendocrine carcinoma. The study includes multiple phases to assess treatment effects and safety in these diverse groups. Participants receive I-DXd via intravenous infusion, typically dosed at 12 milligrams per kilogram, except in hepatocellular carcinoma where the dose is determined separately. The study is divided into three parts Stage 1, Stage 2, and an optional Stage 3 expansion for endometrial cancer, depending on safety and efficacy results. Each participant starts at Stage 1 and may continue to Stage 2 based on observed data. The hepatocellular carcinoma group includes a safety run-in phase to evaluate tolerability. Participants engage in regular assessments including imaging scans to measure tumor response and disease progression. Researchers monitor treatment-related side effects and collect blood samples to study how the drug behaves in the body over time. The studys main goal is to measure the objective response rate up to about 60 months after the first dose. Safety evaluations continue during treatment and for 47 days after the last dose. Participants may remain in the study for up to five years to track long-term outcomes and overall survival.
