An Open-Label, Multi-Center, Phase IIa Trial of PRX302 Treatment of Patients With Locally Recurrent Prostate Cancer After Primary Radiation Therapy
Phase 2
Completed
- Conditions
- Locally Recurrent Prostate Cancer
- Registration Number
- NCT00686088
- Lead Sponsor
- Sophiris Bio Corp
- Brief Summary
The purpose of this study is to determine the therapeutic activity of different concentrations of PRX302 at increasing volumes and/or number of deposits per gram of prostate. Therapeutic activity will be determined based on changes in PSA levels, PSA velocity, PSA doubling time and tumor burden following treatment.
