Filter by:The purpose of this study is to describe patterns in disease management and to describe clinical outcomes, as well as to identify factors influencing physician treatment decisions including reason(s) for treatment choices and trigger(s) for treatment changes and to document healthcare resource utilization used to manage treatment-related complications.
This research is being done to test the safety and anti-cancer activity of the combination of an investigational drug called orteronel, with a drug called itraconazole in the treatment of castration-resistant prostate cancer. Orteronel is an investigational drug known as a 17,20-lyase enzyme inhibitor, meaning that it blocks the formation of male sex hormones. Itraconazole is approved by the Food and Drug Administration (FDA) for the treatment of various fungal infections such as fingernail/toenail infections and other more serious fungal infections. While it has shown evidence of activity against prostate cancer in prior studies, it is not approved for use in cancer. The FDA is allowing the use of orteronel and itraconazole in this research study. In addition to its antifungal properties, itraconazole was discovered to function to block angiogenesis (blood vessel formation to tumors) to block a cellular pathway thought to be important in prostate cancer known as the Hedgehog pathway. Investigators hypothesize that blocking male sex hormone production with orteronel will increase reliance on the Hedgehog pathway in prostate cancer cells which can then be blocked with itraconazole and that the combination of these two drugs will be more effective than either alone.
This study is comparing the safety and effectiveness of abiraterone acetate alone, followed by the addition of prednisone (when the participant's disease worsens or the physician feels it would lessen symptoms of toxicity) versus the current approved treatment regimen which involves the concomitant use of prednisone in conjunction with abiraterone acetate. Additionally, this study is also examining why participants stop responding to treatment with abiraterone acetate by evaluating blood and tissue.
The goal of this clinical study is to determine the safety, tolerability, pharmacokinetics and activity of Seviteronel, a lyase-selective inhibitor of CYP17, in patients with castration-resistant prostate cancer (CRPC).
This study is designed to evaluate the safety and efficacy of combining abiraterone (with prednisone) with cabozantinib in chemotherapy-naïve subjects with bone-metastatic castration-resistant prostate cancer (CRPC).
Until today no current diagnostic tool exists to identify an early objective response when patients with castration-resistant prostate cancer were treated by abiraterone acetate or enzalutamide. According to the Prostate Cancer Working Group, the investigators have to wait 12 weeks before the first evaluation. To know soon that the treatment is effective will be decisive for the oncologist, even more in palliative situation where second effects can't be imposed to patients. In post-docetaxel, the F-choline PET-CT could be used to assess the response of this new therapy. Moreover, the investigators suppose that we can assess an early stage if there is an objective therapeutic response, at 6 weeks of treatment, in order to avoid unnecessarily and expansive treatment. The aim of this study is to assess if it is possible to determine early (6 weeks of treatment)if a F-choline PET-CT could predict the response to abiraterone acetate or enzalutamide in post-docetaxel.
The primary purpose of this research is to describe patient characteristics predictive of an imaging study positive for distant metastases in patients with castration-resistant prostate cancer and no known distant metastases.
A study to evaluate the bioavailability (BA) of a single oral dose of MDV3100 (enzalutamide) formulated as a solid spray dried tablet compared to oral liquid-filled capsules, and the safety and tolerability of oral formulations. Subjects are admitted to the clinic from days 1 to 5, followed by outpatient assessments up to Day 50. They return to the clinic for an end of study visit (ESV) 7-10 days after the last pharmacokinetic (PK) sampling or after early withdrawal.
A drug-drug interaction study to investigate the potential pharmacokinetic interaction between MDV3100 and a cocktail of substrates for pioglitazone (CYP2C8 substrate), S-warfarin (CYP2C9 substrate), omeprazole (CYP2C19 substrate), and midazolam (CYP3A4 substrate).
This randomized phase II trial studies how well glycosylated recombinant human interleukin-7 (CYT107) after vaccine therapy works in treating patients with castration-resistant prostate cancer that has spread to other areas of the body or has not responded to at least one type of treatment. Biological therapies, such as glycosylated recombinant human interleukin-7, may stimulate the immune system in different ways and stop tumor cells from growing. Vaccines made from white blood cells mixed with tumor proteins may help the body build an effective immune response to kill tumor cells. It is not yet known whether glycosylated recombinant human interleukin-7 works better with or without vaccine therapy in treating prostate cancer.
