Filter by:The purpose of this study is to determine the clinical benefits of using a rapidly cycling, non-cross reactive regimen of FDA-approved prostate cancer therapeutic agents in the management of castration resistant prostate cancer. The hypothesis is that the identification of optimal combinations and sequencing of therapies can help prevent or delay the development of therapeutic drug resistance, and can be safely tolerated.
Categorize the clinical parameters and patient determinants that drive physician decision making for treatment selection including Radium-223 for patients with mCRPC.
The research focuses on the safety profile of androgen-deprivation therapy (ADT). The hypothesis is that safety issue, as regards to cardiovascular risk, is not homogenous across the spectrum of androgen-deprivation therapy modalities. Our study will encompass all ADT modalities including intermittent ADT. ADT is a cornerstone therapy in prostate cancer management. Decisions about ADT should weigh improvements in cancer-specific outcomes against potential increased risks for cardiovascular diseases. The potential for harm from ADT should be more precisely defined according to the type of ADT. Those potential risks underscore the importance of better understanding benefits of ADT, especially in contexts where data are still lacking.ADT is also indicated in sexually deviant behavior.
An Open-label extension (OLE), expanded access study, to assess long-term safety of SoluMatrix™ Abiraterone Acetate 500mg (4 x 125 mg qd) with Methylprednisolone (4mg bid) in patients who completed study number CHL-AA-201.
Abiraterone is a selective inhibitor of androgen biosynthesis that potently and irreversibly blocks CYP17, a crucial enzyme in testosterone and estrogen synthesis. A pro-drug of abiraterone, abiraterone acetate (Zytiga®), was developed to overcome its poor bio-availability and is fully converted to the active moiety abiraterone. Abiraterone acetate tablets are administered at a fixed oral dose of 1000mg QD in a fasted state in combination with 10mg prednisolon daily. Abiraterone acetate has a low solubility in aqueous media and a low permeability. The bioavailability of abiraterone acetate is significantly influenced when ingested with food. Ingesting abiraterone acetate with a low fat or a high fat meal resulted respectively in a 5- or 10-fold increase in AUC0-∞. The high and low fat FDA meals used in these food effect studies differ largely from breakfasts taken in everyday life (ca. 800-1000 cal). A continental breakfast contains 160 to 320 calories of which 25-50% is fat, is more compatible with a normal lifestyle and therefore easily sustainable in daily practice. However, the effect of a continental breakfast on the absorption of abiraterone is unknown yet. Furthermore, increasing healthcare costs are a growing concern in all developed countries. Therefore effort should be invested to keep anticancer treatment affordable. A food intervention resulting in a better absorption and enhanced exposure to abiraterone, can lead to a reduced dose, which could significantly impact health care costs for a tumor which is as prevalent as metastatic prostate cancer. Therefore the investigators want to perform a bioequivalent study to investigate what dose of abiraterone with a continental breakfast equals the dose of 1000mg taken in fasted conditions.
The investigators hypothesize software-based fusion/navigation will be accurate to within 3 mm of the reference standard of EM fusion. The investigators aim to evaluate the accuracy of prostate US/MRI software-based fusion/navigation technology.
Cabazitaxel is a second line chemotherapy drug recently approved for the treatment of metastatic castration-resistant prostate cancer. To investigate whether the precautions for the use of cabazitaxel (contraindications, hepatic function, premedication for hypersensitivity, prophylactic treatments, dose and dose adjustment, as well as conditions of administration) are respected in routine practice, an observational cohort study will be implemented in 32 oncology centres of South-West region of France (CABOBS study). The primary objective of this cohort is to evaluate the conformity of cabazitaxel prescriptions with the Summary of Product haracteristics (SPC) in clinical practice (indications and monitoring methods) and according to the conditions of use. Panel of experts were convened to assess the conformity of prescription of cabazitaxel with a Delphi consensus method. The Delphi method is most suited to areas where a limited number of evidences are available to enable a recommendation or guidelines to be drawn. Moreover, all the evaluated items came from an official document provided by the EMA, the SPC of cabazitaxel. Thus, it is expected from the experts to select the most relevant items. In the frame of the CABOBS study, this method will allow to select items of the SPC list according to their importance, and to define the primary objective of conformity to cabazitaxel conditions of use.
The investigators propose to carry out a prospective analysis of physical impact, psychological, cognitive and social of radiotherapy in all patients over 75 years bearer of localized prostate cancer with an indication of curative radiotherapy. This standardized geriatric assessment will collect social information, functional, sensory, cognitive, emotional, motor, nutritional, and medical related to comorbidities . The quality of life of patients will be evaluated by the QLQ C30 (Quality of Life Questionnaire) European Organisation for Research and Treatment of Cancer (EORTC) before starting treatment, at the end of radiotherapy (2 months) and at 6 months. This short follow-up period seems appropriate in this elderly population and will allow an answer within 2 years to the problem raised in clinical practice.
This is a multicenter, cohort study based on medico-administrative data from pathology laboratory registries and drug reimbursement files (CNAM-TS).
We propose to examine the efficacy of couples-based mindfulness-based stress reduction (MBSR) on positive and negative psychological responses to active surveillance (AS) and AS adherence, with a sample of men on AS and their spouses.
