Enzalutamide + External Beam Rt For Prostate

Intermediate Risk Prostate Cancer

This research study is evaluating a drug called enzalutamide in combination with external beam radiation therapy as a possible treatment for prostate cancer. Presently, when participants receive hormonal therapy with radiation therapy for prostate cancer, medications are given to reduce testosterone levels in the blood stream. This leads to side effects such as loss of sex drive, erectile dysfunction (ED) and decrease in muscle strength. The purpose of this study is test another form of hormonal therapy with radiation therapy. The medication called enzalutamide will be used with radiation therapy. Instead of lowering testosterone, enzalutamide blocks testosterone in cells. This study will test if enzalutamide when used with radiation will lower the PSA without causing the side effects associated with medications that lower testosterone in the blood stream.

Hypofractionated Radiotherapy for Prostate Cancer

Prostate Cancer

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 alpha/beta 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 alpha/beta 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 alpha/beta 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.

Study of Sipuleucel-T W/ or W/O Radium-223 in Men With Asymptomatic or Minimally Symptomatic Bone-MCRPC...

Prostate Cancer

This clinical trial studies the effect of radium-223 when added to sipuleucel-T for treating castrate-resistant prostate cancer that has spread to the bone. Sipuleucel-T is an autologous cellular immunotherapy designed to stimulate an immune response against prostate cancer. It has been suggested that the immune response may be strengthened by radiation therapy. Therefore this study is testing whether radium-223 added to sipuleucel-T increases the immune response and anti-tumor effect against prostate cancer.

EXTEND Exercise Trial

Non-metastaticHormone naïve Prostate Cancer

This study will examine the effect of supervised exercise training on cardiopulmonary function in men receiving the combination of enzalutamide (ENZ) and androgen deprivation therapy (ADT) for treatment of non-metastatic, hormone-naïve prostate cancer. No study to date has examined the efficacy, tolerability, and safety of exercise training to prevent and/or mitigate common adverse toxicities in men receiving combination androgen suppression therapy for hormone-naïve prostate cancer.

Stereotactic Body Radiation Therapy in Treating Patients With Metastatic Breast Cancer, Non-small...

Male Breast CarcinomaProstate Adenocarcinoma6 more

This phase I trial studies the side effects and the best dose of stereotactic body radiation therapy in treating patients with breast cancer, non-small cell lung cancer, or prostate cancer that has spread to other parts of the body. Stereotactic body radiation therapy delivers fewer, tightly-focused, high doses of radiation therapy to all known sites of cancer in the body while minimizing radiation exposure of surrounding normal tissue.

Phase II Study of SBRT as Treatment for Oligometastases in Prostate Cancer

Oligometastatic Prostate Cancer

This study aims to probe the effect of SBRT as a treatment oligometastases of prostate cancer, regardless of basal treatment received, and I know the response, biochemical control, the progression-free survival as well as their impact on quality of life. Primary Objective: Local and symptomatic oligometastases Control of prostate cancer treated by SBRT. Secondary Objectives: Analyzing biochemical progression rates, progression-free survival, chemotherapy-free survival and overall survival. Analyze toxicities and quality of life of patients before and after treatment

Study of ES414 in Metastatic Castration-Resistant Prostate Cancer

Prostate Cancer

The study will be conducted in 2 Stages. The primary objective of Stage 1 of the study is to identify the maximum tolerated dose (MTD) of ES414 administered intravenously to patients with mCRPC. Secondary objectives are to evaluate the tolerability, pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity, cytokine response, and clinical activity of ES414. The primary objective of Stage 2 of the study is to evaluate the clinical activity of ES414 in patients that have or have not received prior chemotherapy. Secondary objectives are to further characterize the safety profile, PK, PD, and immunogenicity of ES414.
