What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

What participation involves

  • Procedures mentioned: Biopsies, Blood draws

Only what the study's summary and detailed description on ClinicalTrials.gov say. Time periods may describe the whole study or a part of it — ask the study team what applies to you.

Show the study's own words
  • "Clinical response as evaluated by changes in serum PSA level and digital rectal examination as well as by histological alterations on re-biopsy and prostatectomy such as the presence of apoptosis, necrosis, tumor proliferation and immunologic response, will be assessed following HSV-tk + valacyclovir treatment."
  • "Blood samples will be taken for systemic immunological response, blood counts and liver functions tests."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

This is a prospective phase II study to assess the efficacy and toxicity of HSV-tk+ valacyclovir gene therapy in combination with androgen deprivation therapy, brachytherapy, external beam radiotherapy, and prostatectomy in previously untreated high-risk prostate cancer.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
