Brief Summary

This is a proof-of-concept study designed to investigate HER3-DXd monotherapy in locally advanced unresectable or metastatic solid tumors. The study is enrolling cohorts of participants with melanoma \[cutaneous/acral\], squamous cell carcinomas of the head and neck (SCCHN), HER2-negative gastric cancer ovarian carcinoma, cervical cancer, endometrial cancer, bladder cancer, esophageal carcinoma, pancreatic carcinoma, prostate cancer, second-line gastric cancer, lung cancer, and breast cancer.
