Trastuzumab in HER2-positive Biliary Tract Cancer

• Status: Completed
• Trial end date: 2021-01-04
• Target enrollment: 0
• Participant gender: All

Summary

Trastuzumab is approved for the treatment of HER2-positive breast cancer and gastric cancer. The recent study showed that HER2 overexpression or amplification is noted about 5-15% of total biliary tract cancer patients. The aim of this study is to evaluate the efficacy and safety of trastuzumab in the combination of current standard gemcitabine plus cisplatin.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Changhoon Yoo
• Treatments: Cisplatin; Gemcitabine; Trastuzumab
