VA-BAT Trial Summary

This trial will test whether intermittent high-dose testosterone therapy can shrink tumors in men with DNA repair deficiency.

Who is the study for?
This trial is for men over 18 with advanced prostate cancer that's resistant to hormone therapy. They must be on androgen deprivation treatment, have specific gene mutations (ATM, CDK12, CHEK2), and an ECOG Performance Status <2. Excluded are those with dementia, other cancers being treated, liver metastases or significant heart disease.Check my eligibility
What is being tested?
The study tests if high dose testosterone can benefit patients whose prostate cancer has DNA repair deficiencies due to ATM, CDK12 or CHEK2 alterations. It's a prospective study checking the hypothesis that genetically unstable tumors respond well to this treatment.See study design
What are the potential side effects?
While not explicitly listed in the provided information, potential side effects of high dose testosterone may include acne, sleep apnea, enlarged breasts, testicular shrinkage and increased risk of certain cardiovascular events.
