Filter by:The purpose of this study is to determine whether female partners of African American men can promote initiation of a discussion with a healthcare provider about prostate cancer screening when the partner is supported by a print message designed to provide relevant information and strategies for her to use in this effort.
Eligible subjects must have completed 6 doses of treatment of radium-223 dichloride and experienced no radium-223 dichloride-related SAEs (serious adverse events) or CTCAE (Common Terminology Criteria for Adverse Events) Grade 3 or 4 adverse event during or after the initial course of radium-223 dichloride that led to the discontinuation of treatment. 40 Subjects will be enrolled and will receive up to 6 doses of radium-223 dichloride 50 kBq/kg IV every 4 weeks. The subject will be evaluated for AEs (adverse events) and laboratory tests at each visit every 4 weeks, prior to receiving radium-223 dichloride. After the end of treatment visit the subjects will enter the active follow up period. Related AEs and SAEs and Lab tests will be evaluated at each visit every 4 weeks for the first 12 weeks, then every 12 weeks for up to 2 years after the last dose of radium-223 dichloride. After the 2 years of active follow-up, subjects will enter the long-term follow-up period and will be followed via telephone follow-up at 6-month intervals for late toxicities and survival up to 7 years after the last dose of radium-223 dichloride or until death. Joint safety reviews will regularly take place to oversee safety of the subjects conducted at regular intervals. An interim analysis of the safety data will be conducted during the study.
We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.
The purpose of this study is to evaluate the safety and effectiveness of AD5-SGE-REIC/Dkk-3 in patients with localized prostate cancer.
To evaluate the efficacy and safety of the best standard of care plus BAY88-8223 in Japanese patients with CRPC and bone metastases after a multiple administration
The purpose of this study is to see how long it takes for prostate cancer to come back in patients who have had surgery to remove their prostate gland (radical prostatectomy), while being treated with enzalutamide (formerly known as MDV3100). Enzalutamide is known as an androgen-receptor signaling inhibitor, which means that it blocks activity of the male hormone, testosterone. Most prostate cancers are dependent on testosterone for growth. In this study, patients will take enzalutamide after surgery to see if it keeps their cancer from coming back.
This is a Phase I/IIa study evaluating the safety and feasibility of [89Zr]Df-IAB2M as an immunoPET tracer for metastatic prostate cancer. Individuals participating in this study will have a FDG PET scan, as well as four (4) PET scans (over a 3 day period) following the injection of [89Zr]Df-IAB2M PET tracer. Three different dosing levels will be explored. The purpose of the study is to demonstrate the safety of [89Zr]Df-IAB2M, ability to detect prostate cancer, and optimal time point and dose level for imaging.
External beam radiotherapy (RT) is one of the standard curative treatment options for patients with prostate cancer (PC). Several randomised trials have shown excellent long-term biochemical outcome with higher radiation doses. Nowadays, RT for PC commonly consists of delivering 74-80 Gy in 2 Gy fractions, resulting in an overall treatment time of 7-8 weeks. The sensitivity of different tissues to fractionation changes can be quantified through the α/β ratio in the linear-quadratic model. Dose-response analysis of PC patients treated with both external beam RT and brachytherapy has led to the hypothesis that the α/β ratio of PC is lower than for most other tumors and approaches a value characteristic of late responding tissues. Values between 1.2 and 3.9 Gy have been calculated. If the α/β ratio of PC is indeed low, then hypofractionating RT treatments can theoretically maintain high bioequivalent tumor doses, shorten overall treatment time and decrease late toxicities.The advantages in terms of patient convenience and treatment cost are obvious. There is level I evidence that shows that hypofractionated radiotherapy schedules have at least equivalent biochemical outcome with only a small increase in acute but not late toxicity when compared to conventional fractionation RT schedules. Results on different hypofractionation schedules have been reported, however the optimal hypofractionation is not clear so far. In this randomised trial we would like to compare 2 different radiotherapyschedules: 16 fractions à rato of 4 fractions a week versus 25 fractions à rato of 5 fractions a week. The incidence on acute toxicity and early late toxicity (i.e. within 2 year post radiotherapy) and the impact on quality of life will be registrated and compared. The study will be performed in 2 stages. For stage 1, sample size was calculated to rule out an upper limit of 40% of patients with RTOG grade 2 or worse bowel (GI) complications with an expected rate of 25%, based on a one-stage Fleming-A'Hern design. A power of 83.0% (alpha level 0.038 one-sided) was obtained when including 72 patients per group (144 patients in total). If 22 or more patients out of 72 had grade 2 or worse GI complications, then the study arm was to be rejected. To allow for a dropout of 10%, 160 patients were included in stage 1. Sample size for stage 2 was calculated analogously allowing ruling out an upper limit of 35% of patients with RTOG grade 2 or worse GI complications with an expected rate of 25%. When including 155 patients per group (310 in total) a power of 85.7% (alpha level 0.049 one-sided) was obtained. If 45 or more patients out of 155 had grade 2 or worse GI complications, then the study arm was to be rejected. The sample size for stage 1 and stage 2 combined was set at 346 (173 per group), with a 10% allowance for dropout.
Prostate cancer is the second most incident cancer among male population worldwide. Radiation therapy by itself or along with surgery and chemotherapy are the main treatments for prostate cancer however prostate cancer cells are only modestly responsive or even unresponsive to the cytotoxic effects of radiotherapy. Recently some in vitro and in vivo studies showed radiosensitizing and radioprotective effects for curcumin. No clinical trial has been done in this area and it is not yet known whether radiation therapy is more effective with or without curcumin supplements in treating patients with prostate cancer.
This randomized pilot phase I trial will evaluate if quercetin enhances the uptake of green tea polyphenols in the prostate tissue of men taking green tea extract and undergoing radical prostatectomy. Side effects of green tea extract and quercetin in combination with green tea extract will also be evaluated. In preclinical studies, green tea polyphenols have anticancer and cancer preventative effects in a number of malignancies. Likewise, in preclinical studies quercetin was found to enhance the anticancer effects of green tea. This trial is designed to translate these findings forward in a short-term human intervention trial.
