Phase 2 BAT trial from downunder: WOMBAT trial

[Maxone73]

The WOMBAT Trial (Working Out M0 Bipolar Androgen Therapy) investigates the efficacy of bipolar androgen therapy (BAT) in extending metastasis-free survival for patients with M0 castration-resistant prostate cancer (CRPC) experiencing rising PSA levels on darolutamide, without visible metastases.

This Phase 2, open-label trial targets 69 participants in New South Wales, Australia, with recruitment spanning November 2024 to August 2027.

Participants will receive testosterone enanthate (500mg, intramuscularly) in 56-day cycles, alongside darolutamide and standard castration therapy. The study also examines safety, PSA progression, quality of life, and hormone kinetics. Sponsored by Bayer and led by the ANZUP Cancer Trials Group, this innovative trial aims to redefine CRPC treatment pathways by reintroducing testosterone in controlled bursts.

The above website is for aPatent by dr Bieber for “dogosterone” very important for dogs who have been brutally operated on by spaying and neutering instead of doing it by sparring the hormone producing organs in our lovely pets.

That patent is a great read and my baby is doing so much better.

Great find and very important to us warriors like me who are doing BAT with daro.

Is there a way to get their algorithm i wonder.

Very promising trial and I especially love the name -- WOMBAT !!! Most urologists hate the idea of BAT or T replacement therapy. Maybe a change may be coming.

[KocoPr in reply to fast_eddie]

That’s due to their training on expensive pharma solutions.

[PCaWarrior in reply to KocoPr]

Education plays a large part. MMost practicing MOs were taught that T is the enemy. My MO is in her thirties and had no problem with my doing BAT.
