New Clinical Trial: A Phase 2 Study of T-DXd in Patients With Selected HER2 Expressing Tumors (NCT04482309)

WHY IT MATTERS

This trial offers patients with HER2-positive rare cancers like biliary tract, cervical, endometrial, ovarian, and pancreatic cancer access to a targeted therapy that has demonstrated effectiveness in other cancer types—potentially providing a new treatment option where few exist.

Researchers are testing a cancer drug called trastuzumab deruxtecan (T-DXd) in patients with several types of rare and uncommon cancers that have a specific protein marker called HER2. The study includes seven different cancer types in the first part, including bladder, bile duct, cervical, uterine, ovarian, and pancreatic cancers. This drug has already shown promise in breast and stomach cancers, and doctors want to see if it works in these other cancer types too.

NCT ID: NCT04482309 Status: ACTIVE_NOT_RECRUITING Conditions: Part 1: Bladder, Biliary Tract, Cervical, Endometrial, Ovarian, Pancreatic Cancer, Rare Tumors, Any Tumor Type Excluding Breast, Gastric, Colorectal Cancer, Part 2: HER2 Expressing/Amplified Solid Tumors Excluding Breast, Gastric, Colorectal Cancer Phase: PHASE2 Enrollment: 477 Sponsor: AstraZeneca Summary: This is an open-label, multi-center, multi-cohort, Phase 2 study to evaluate the efficacy and safety of trastuzumab deruxtecan (T-DXd) for the treatment of selected HER2-expressing tumors. This study will consist of Part 1 which includes 7 cohorts of: urothelial bladder cancer, biliary tract cancer, cervical cancer, endometrial cancer, ovarian cancer, pancreatic cancer, and rare tumors; and Part 2 which includes 5 cohorts A to E of: A) any tumor type that is HER2 IHC 3+ (excluding breast, gastr

ASK YOUR DOCTOR

If you have one of the cancers listed in this trial and your tumor has HER2 expression, ask your oncologist whether you might be eligible or if there are similar trials currently recruiting in your area.
