Filter by:Prostate cancer is the most common non-skin tumor diagnosed in men and the second leading cause of cancer death in men in Western countries. Between 10-20% of patients are diagnosed at metastatic stage and about half of those diagnosed in early stages will develop metastases. After the clinical benefit of mitoxantrone and the improved survival of 2-3 months provided by docetaxel in first line, the second search is driven to look for effective second lines treatments. In recent years, there are new drugs for the treatment of prostate cancer, revolutionizing the therapeutic sequence and survival. Thus, androgen deprivation therapy, treatment of choice, induces an improvement of symptoms in approximately 70-80% of patients, but it is limited by the development of mechanisms of resistance to androgen deficiency. Docetaxel was the first chemotherapy drug to increase survival in patients with metastatic prostate cancer. The second cytotoxic drug approved in the second line treatment of metastatic CRPC has been cabazitaxel. Enzalutamide improves survival in patients with metastatic CRPC who had progressed to chemotherapy and also in patients who had not received chemotherapy. To date, there are no biomarkers available that allow us to identify which patients from a clinical or molecular view are those that will be able to benefit from the treatment options currently available. The presence of the TMPRSS2-ETS rearrangement has been shown to correlate with efficacy in clinical practice abiraterone. There is scientific and preclinical background that makes one suspect that the molecular alteration may influence the same way enzalutamide antiandrogen activity, but it has not been determined to date. The objective of this study is to determine whether the efficacy and safety of enzalutamide, when administered to patients with castration resistant prostate cancer prior to administration of docetaxel is influenced by the presence or absence of the fusion gene TMPRSS2- ETS.
The purpose of the study was to understand if there was benefit in continued treatment with a medicine called enzalutamide, when starting treatment with docetaxel and prednisolone (a standard chemotherapy for prostate cancer), after the prostate cancer had gotten worse when treated with enzalutamide alone.
Asymptomatic men with progressive metastatic Castration-resistant prostate cancer (CRPC) post- treatment with abiraterone acetate (pre-chemotherapy for metastatic disease) will be treated on a randomized, multi-Institutional open label study to determine if treatment with intramuscular T given on a dose/schedule designed to result in rapid cycling from the polar extremes of supraphysiologic to near castrate levels [i.e. Bipolar Androgen Therapy (BAT)] will improve primary and secondary objectives vs. enzalutamide as standard therapy.
The recent data suggest that cancer cells at the origin of prostate cancer metastases can be detected in an early stage. Available techniques allow phenotypic analysis of cancer cells in circulating blood (cellsearch) or in marrow hematopoietic (flow cytometry). Pilot study on 180 patients infected by prostate cancer at all stage of disease, show that c-met marker , integrin alpha 2 and 6 expressed in marrow and quantified by flow cytometry were predictor of metastatic progress. In this new study the investigators will analyze antibody panel by cellsearch and flow cytometry on marrow sample of castration-Resistant prostate cancer patients.
The purpose of this study is to test the safety and side effects "of "ultra-hypofractionated" radiation therapy when used after brachytherapy (radiation implants). This treatment delivers a higher radiation dose with each treatment over a shorter period of time.
Dose finding safety study of VAL201 in cancer patients.
The purpose of this study is to examine the safety and effectiveness (how well the drug works) of two different doses (3 mg/kg and 10 mg/kg) of Ipilimumab (Yervoy™) in patients with metastatic castration resistant prostate cancer.
The purpose of this study is to find out if Radium-223 is effective in reducing cancer pain within 12 weeks of treatment. In order to see if Radium-223 is effective, the patient's level of pain will be followed throughout the study.
This proposed 5-year Redes En Acción research study involves a mixed-methods approach that occurs in two phases across two distinct and diverse HL communities. The RCT involves a 2 X 4 randomized repeated measures design with experimental condition (combined patient navigation [PN] over 3 months with access to LCNS PN services[PNLCNS] vs. a PN only condition) as the between-groups factor, and time-point (baseline/pre-randomization [T1]; post-PNLCNS [about 3-months post-T1; T2], and about 6- [T3] and about 12-months [T4] follow-up post-T2) as the within-groups factor; total follow-up is 15 months. The investigators will compare the effects of the PNLCNS and PN only conditions on QOL and treatment follow-up compliance in 300 (after attrition; n=100, Chicago and n=100, San Antonio) breast, colorectal and prostate HL cancer survivors with no evidence of metastatic disease.
This is an open-label exploratory study of CTAP101 Capsules in patients with bone metastases arising from either breast or prostate cancer, who are taking anti-resorptive therapy.
