Bipolar Androgen Therapy Yields Promising Results in Prostate Cancer

Bipolar Androgen Therapy Yields Promising Results in Prostate Cancer
Bipolar androgen therapy, where the body is alternately flooded with and starved of testosterone, is safe and effective for the treatment of metastatic prostate cancer, according to a study presented at the 28th Symposium on Molecular Targets and Cancer Therapeutics in Munich, Germany. The researchers, led by Samuel Denmeade, MD, professor of oncology at Johns Hopkins University School of Medicine in Baltimore, presented results from 47 men with metastatic prostate cancer resistant to chemical or surgical treatment who have completed at least three cycles of bipolar androgen therapy. For the study, RESTORE (NCT02090114), the researchers injected a high dose of testosterone (400 mg) into the muscle of the men every 28 days. The men continued to receive luteinizing hormone-releasing hormone (LHRH) agonist therapy to inhibit their natural testosterone production, but stopped treatment with the anti-cancer drugs Zytiga (abiraterone) and Xtandi (enzalutamide) that inhibit androgen receptor signaling, against which they had developed resistance. "Our goal is to shock the cancer cells by exposing them rapidly to very high, followed by very low, levels of testosterone in the blood," Denmeade said in a press release. The first arm of the study looked at 30 men who were treated with testosterone after their disease became resistant to Xtandi and started to progress. The results showed the levels of prostate specific antigen (PSA) decl

    How can I get this information to my Doctor directly. I fit most of these conditions and am on Xtandi now and PSA is back down to 0.47 for now. I am just looking to the future when the Xtandi stops working.
    Thank you for your help, Herschell

    • Jim Davidson says:

      I became resistant to both Casodex and Xtandi. 24 weeks of chemo was a waste of time (except it made my hair curly – a definite improvement). I followed that with several months of a clinical trial. I watched as my cancer beyond my bones to my livers. What finally worked was a combination Opdivo and medical marijuana taken as suppositories. My PSA dropped from 318 down to 0.34. All but three of the 20+ tumors in my liver dissolved. Opdivo worked because I had amplified PD-L1 receptors (>80%). The THC in the marijuana binded to the CB2 receptors on the cancer causing aptopsis and amplifying Opdivo’s T-cell immune response. Moral of the story: There are always options. Even when your three months away from death.

      • Herschell Atkinson says:

        Thanks Jim. It was not clear to me if you tried the BAT or if you went straight to the Opdivo (which I have never heard of) and marijuana?
        Good luck with your treatment,

      • Herschell Atkinson says:

        Good morning Jim.
        Would you mind sharing the information on your doctor and the facility where you are getting this last treatment,i.e. The Opdivo and marijuana.
        I have a very close friend who just found out yesterday that his liver is involved and he is very depressed.
        Would appreciate any information you feel comfortable sharing.
        Thanks, Herschell

            Hello from Sweden Jim, i read about your treatment for advanced PC and got very interested…Im 56 and failed Casodex, just started Xtandi and responding ok…my cancer is seen i 2 lymhnodes…thats the only thing seen on a PET-CT…i had surgery in 2007 and radiation…but no chemo so far…so i guess the Opdivo or Keytuda is further down the line, just want to ask you how you got to take the PD-L1 test…was it just a blood test or how is it done?. Is the combination with medical maijurana important? Hope this reaches you Jim, and i hope to hear from you soon. Best regards//Arne Johansson

      • paul fasoli says:

        very interesting… psa was on the rise….I stopped casadex and finasteride , because it tears your body apart.took it for three years, psa started to rise after off hormone therapy for one year, to 4.5, took cannabis suppositories for one month…psa went to 1.5.
        thanks for reassuring me of my method,i will look into opdivo.
        look into apple cider vinegar enemas. kills candida, kills cancer, they are finding cancer is a fungus, apple cider vinegar kills fungus. regards

    Hello world…Bless you all! I received my 1st shot of testosterone (400mg) on Tuesday 3/28/2017 @ Johns Hopkins in Baltimore, Md. This the transformer study. On Wednesday afternoon, day two, back spasms of excruciating pain developed in my back…feels like the muscles that wrap around the rib cage in my back. I am hurting as I type! Took 2.5 advil…alternating heat and ice. Hot tub helps some! Difficult to relax! Breathing can be painful as well when spasms are pain level 10 on 1 to 10! Called JHH yesterday 3/30! We shall monitor! Pain becomes more severe in afternoon. I am 65 years old…diagnosed in December 2008. Open to suggestions for spasms! Good luck to all!

    • paul fasoli says:

      hi mike, for spasms I would try calcium. magnesium , and zinc, all in one tab, also hot, cold treatment, and quinine sulphate pills or their is quinine in quinine water.
      do you have a tele number for activity doing bap…would like to look into. thank you

    • John Phillipe says:

      Mike, I am considering the BAT Therapy in the future. How are you responding? How are your muscle spasms ?

  3. Stephen B. Strum, MD, FACP says:

    I am a medical oncologist with 34 years in the field of PC (prostate cancer). I can appreciated these messages but they seem to be all over the proverbial playing field.
    PD (programmed death)-1 receptors are determined by tissue biopsy and not by blood. IHC (Immunohistochemistry) is usually the lab technique used to identify Programmed cell death protein 1 (PD-1) and the substances that interact with PD-1 (i.e., ligands PD-L1 and PD-L2). These proteins play a role in causing an immunosuppressive tumor microenvironment. Commercially available agents used to INHIBIT these proteins are called checkpoint inhibitors & include ipilimumab (Yervoy®), pembrolizumab (Keytruda®) & nivolumab (Opdivo®). There are scant articles on the clinical use of these agents in PC, and of those published so far, the results are not startling. So it is with keen interest that I read the comment on nivolumab (Opdivo®) inducing a major response. The dose & scheduling should be shared on this site. However, this thread is SUPPOSEDLY about bipolar androgen therapy (BAT) & not about checkpoint inhibitor therapy. It would have been “nice” to Jim Davidson to relate the specifics of his treatment in his email & not via facebook (of course this is my opinion). And there is nothing in the peer-reviewed literature as recently as a few months ago on the value of any form of cannabis be it THC, cannabidiol (CBD) or any other metabolite on prostate cancer in humans. That so far is all hearsay.

      diagnosis 2007, radiotherapy 2008, Lucrin Hormonreduction 1 year
      T2b, PSA 5,6, 12 needles with cancer, Gleason 4+4
      after treatment: psa 0.5
      recitif 2017, April 2017 1.8, means p.m. 0.1 progression
      what is to do?

    • Dan says:

      Thank You Dr Strum!
      Was there a recent article, with Dr Beer anouncing amazing activity with Keytruda. Is it only people who express pd1 or pdl1 that respond to Keytruda
