Clinical Trials

Trial Description:
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 enroll 7 tumor-specific cohorts: urothelial bladder cancer, biliary tract cancer, cervical cancer, endometrial cancer, ovarian cancer, pancreatic cancer, and rare tumors.

Study hypothesis: Trastuzumab deruxtecan will show meaningful clinical activity and a favorable risk benefit profile in selected HER2-expressing solid tumors.

Eligibility Requirements:
- Locally advanced, unresectable, or metastatic disease based on most recent imaging.
- The respective cohorts for patient inclusion are:
- Cohort 1: Biliary tract cancer
- Cohort 2: Bladder cancer
- Cohort 3: Cervical cancer
- Cohort 4: Endometrial cancer
- Cohort 5: Epithelial ovarian cancer
- Cohort 6: Pancreatic cancer
- Cohort 7: Rare tumors: This cohort will consist of patients with tumors that express HER2, excluding the tumors mentioned above, and breast, non-small cell lung cancer, gastric cancer, and colorectal cancer.
- Progressed following prior treatment or who have no satisfactory alternative treatment option.
- Prior HER2 targeting therapy is permitted.
- HER2 expression for eligibility may be based on local or central assessment.
- Has measurable target disease assessed by the Investigator based on RECIST version 1.1.
- Has protocol- defined adequate organ function including cardiac, renal and hepatic function.
Exclusion Criteria:
- History of non-infectious pneumonitis/ILD that required steroids, current ILD, or where suspected ILD that cannot be ruled out by imaging at screening
- Lung-specific intercurrent clinically significant severe illnesses
- Uncontrolled infection requiring intravenous (IV) antibiotics, antivirals, or antifungals
- Pleural effusion, ascites or pericardial effusion that requires drainage, peritoneal shunt, or Cell-free and Concentrated Ascites Reinfusion Therapy (CART
- Known Somatic DNA mutation of HER2 (ERBB2) without tumoral HER2 protein expression.
- Primary diagnosis of adenocarcinoma of the breast, adenocarcinoma of the colon or rectum, adenocarcinoma of the gastric body or gastro-esophageal junction, or non-small cell lung cancer.
- Medical conditions that may interfere with the subject's participation in the study.
