This study is designed to assess the efficacy and safety of ifinatamab deruxtecan (I-DXD) in the following tumor types: endometrial cancer (EC); head and neck squamous cell carcinoma (HNSCC); pancreatic ductal adenocarcinoma (PDAC); colorectal cancer (CRC); hepatocellular carcinoma (HCC); adenocarcinoma of esophagus, gastroesophageal junction, and stomach (Ad-Eso/GEJ/gastric); urothelial carcinoma (UC); ovarian cancer (OVC); cervical cancer (CC); biliary tract cancer (BTC); human epidermal growth factor 2 (HER2)-low breast cancer (BC); HER2 immunohistochemistry (IHC) 0 BC; and cutaneous melanoma.
Participant must have at least 1 lesion, not previously irradiated, amenable to core biopsy and must consent to provide a pretreatment biopsy tissue sample. An archival tumor tissue sample obtained within 6 months of consent and after progression during/after treatment with the participant's most recent cancer therapy regimen is also acceptable.
Participants ages ≥18 years (follow local regulatory requirements if the legal age of consent for study participation is >18 years).
At least 1 measurable lesion on computed tomography (CT) or magnetic resonance imaging (MRI) according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1), as assessed by the investigator.
