First, I must apologize for having ignored the blog over the last two weeks. I have been intensely focused on the launch of a new project that we at Malecare have been developing. It has managed to take up every available second of my time. At this moment, I am not able to describe much [...]
An alternative to standard hormone therapy (ADT) using luteinizing hormone-releasing hormone (LHRH) analogs like leuprolide (Lupron®, Eligard®), goserelin (Zoladex®), triptorelin (Trelstar®), and histrelin (Vantas®) for men with advanced prostate cancer, but often not used is estradiol (a form of estrogen). When estrogens were first used as a therapy for men with advanced prostate cancer they [...]
We have long known that Zoledronic Acid (Zometa) decreases a man’s risk of developing skeletal-related events (SREs) in men with castration-resistant advanced prostate cancer (CRPC) and bone metastases. In a phase III study that evaluated efficacy and safety of earlier treatment with Zometa in men with advanced prostate cancer which is still castration-sensitive found that [...]
Ra-223 (Alpharadin)is an alpha-pharmaceutical targeting bone metastases (mets) with high-energy, short-range (< 100 ?m) alpha-particles. Currently it has been submitted to the FDA for approval, which we hope will happen by August 2013. In the phase 3, double-blind, randomized, multinational ALSYMPCA study, Ra-223 significantly improved overall survival (OS) in men with castrate resistant advanced prostate [...]
Another interesting research abstract presented at the Genitourinary Cancers Symposium in Orlando Florida this month found that men with prostate cancer who were on chemotherapy who had also received anticoagulant (blood-thinners) medications experienced improved overall survival rates compared to men who did not take anticoagulants drugs. This retrospective study involved the reviewed of the medical [...]
Ra-223 is an investigational alpha-pharmaceutical targeting bone metastases (mets) with high-energy, short-range alpha-particles. The recently completed phase 3, double-blind, randomized, multinational ALSYMPCA study showed that Ra-223 significantly improved over all survival (OS) in CRPC men with bone mets by a median increase of 3.6 months compared with placebo (median OS: 14.9 vs 11.3 mo; P [...]
At the recent 2013 2013 Genitourinary Cancers Symposium there was an abstract presented that updated data from the COU-AA-302 clinical trial of Abiraterone Acetate (Zytiga) with prednisone. The updated data confirms that Zytiga with prednisone improves overall survival (OS) in men with metastatic castrate resistant prostate cancer (mCRPC) post-docetaxel therapy (chemotherapy)(Lancet Oncol 2012;13:983-92). The trial [...]
There was a recent interview in the Pharma Strategy Blog with Dr. Bertrand Tombal , an academic urologist in Belgium. Dr. Tomal discussed several of the new advances in the treatment od advanced prostate cancer with an emphasis on the potential future of Enzalutamide (Xtandi). Like bicalutamide (Casodex), Xtandi works by blocking (inhibiting) testosterone from [...]
Men who are diagnosed with high risk prostate cancer, meaning they are more likely to develop advanced prostate cancer are usually treated with Radiotherapy (RT) and long term androgen blockade (AB). Currently, we do not know what is the optimal duration of AB. Looking at this problem, the researchers conducted a randomized study to compare [...]
More on Sipuleucel-T (Provenge) from the 2013 The last two abstracts that I want to speak about that were presented at the conference that pertained to Provenge speak to its efficacy. The first looks at changes in circulating tumor cells (CTC) and the second to the onset of the use of opioid painkillers. Abstract #40 [...]
