Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Use of Enhertu as a Subsequent Line of Therapy in HER2-Positive Metastatic Castration-Resistant Prostate Adenocarcinoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This Phase II clinical trial aims to evaluate the efficacy and safety of Enhertu in HER-2 positive mCRPC who have progressed on prior androgen deprivation therapy and novel hormonal agents, who are either not candidates for or have refused taxane based chemotherapy. Led by Dr. Maneesh Jain at the Washington DC VA, the open label multi center study will include 60 participants treated with Enhertu. Primary endpoints focus on objective response rates, while secondary measures include safety, progression-free survival, overall survival, and quality of life.

Enhertu for HER2 positive metastatic castrate resistant prostate cancer

Group Type EXPERIMENTAL

Enhertu

Intervention Type DRUG

This is an open label, multi-center, single arm, phase II study designed to investigate the anti-tumor activity, efficacy and safety of Enhertu in HER2-positive metastatic castrate-resistant prostate cancer patients who progressed on androgen deprivation therapy and novel hormonal agents (such as Abiraterone and Enzalutamide), who also progressed, refused, or were not candidates to receive taxane-based chemotherapy.
