Active clinical trials for "Prostatic Neoplasms"

You are being asked to take part in this study because you have prostate cancer that has spread to other parts of the body. This is an investigational study. Prednisone is FDA-approved and commercially available. Abiraterone acetate is FDA-approved and commercially available, but is still being researched. Sunitinib malate is FDA-approved for the treatment of gastrointestinal tumors and renal cell carcinoma, and dasatinib is FDA approved and commercially available for certain types of leukemia. The use of these drugs in prostate cancer and in combination with abiraterone acetate and prednisone is investigational. Up to 180 patients will be enrolled in this study. All will be enrolled at MD Anderson.

The purpose of this study is to evaluate the effectiveness of ProstAtak® immunotherapy in combination with radiation therapy for patients with intermediate-high risk localized prostate cancer. ProstAtak kills tumor cells and stimulates a cancer vaccine effect. Killing tumor cells in an immune stimulatory environment induces the body's immune system to detect and destroy cancer cells. ProstAtak has shown synergy with radiation without added toxicity and lower than expected recurrence rates in previous clinical trials. The hypothesis is that ProstAtak can lead to improvement in the clinical outcome for patients with prostate cancer. Participants will be randomized to the ProstAtak or control arm at a 2:1 ratio. Both arms receive standard external beam radiation therapy. Short-term androgen deprivation therapy may be given but is not required.

This phase I trial studies the side effects and the best dose of Akt inhibitor MK2206 together with hydroxychloroquine in treating patients with advanced solid tumors, melanoma, prostate or kidney cancer. Akt inhibitor MK2206 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as hydroxychloroquine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving Akt inhibitor MK2206 together with hydroxychloroquine may kill more tumor cells than giving either drug alone.

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. It is not yet known which dose of radiation therapy is more effective in treating patients with prostate cancer. PURPOSE: This randomized phase III trial is comparing two radiation therapy regimens in treating patients with prostate cancer receiving hormone therapy.

The purpose of this study is to test the effectiveness of the experimental drug, 177Lu-J591 in combination with ketoconazole and hydrocortisone against prostate cancer.

The hypothesis of the proposed study would be that, due to the six months of total androgen blockade, which would include neoadjuvant hormonal therapy for four months and concomitant hormonal therapy for two months with irradiation, the investigators could reduce local failure rates for these two dosage levels, namely 70 Gy and 76 Gy. Since increasing the dose to the prostate also seems to reduce local relapse rates, the results of the two hormonal therapy groups would be compared with the results of prostate irradiation at doses of 76 Gy. This study would verify the possibility of compensating a six Gy dosage increase of radiation therapy with six months of hormonal therapy between the 70 Gy and 76 Gy groups who received hormonal therapy, and also match these results with a dose escalation to the prostate of 76 Gy. In the future, this could result in more therapeutic choices, such as reducing the doses of radiation therapy and, consequently, its related complications, if hormonal therapy proves to be beneficial; or rather, to continue in the direction of dose escalation for this intermediate-risk patient group, everything being correlated to the side effects of hormonal therapy and irradiation.

Treatment of recurrent oligometastatic prostate cancer may be enhanced by the addition of Hydroxychloroquine to the current treatment regimens. Potential benefits of Hydroxychloroquine include delayed disease progression and delayed initiation of androgen deprivation therapy (ADT), thus lessening morbidity, distressing side effects, and improving functioning and quality of life in men with recurrent prostate cancer. Building on prior research at Markey, patients recently diagnosed with recurrent oligometastatic prostate cancer will be approached about participating in this study. Per standard of care, these patients undergo either surgery or radiation, in addition participants of this clinical trial will also receive Hydroxychloroquine (400 mg per day, oral medication) for 3 months. It is expected that a participant will exhibit a 50% increase of tumor suppressor PAR-4, as well as few, if any, negative side effects from Hydroxychloroquine.

The hypo-FLAME 2.0 study is a multicenter phase II study (n=124) investigating the feasibility and safety of a reduction in the overall treatment time of radiotherapy for prostate cancer patients, making use of hypofractionated stereotactic body radiotherapy with focal boosting. We are looking for the optimal overall treatment time for this treatment strategy in the Hypo-FLAME 2.0 trial. In this study the total treatment time will be halved (15 days) in comparison with the total treatment time in the former hypo-FLAME trial (29 days) (NCT02853110).

This extended clinical investigation is a multicenter, prospective, single arm study intended to provide continued access of the Exablate Model 2100 device (Exablate Prostate) to patients for treatment of prostate lesions and collect additional safety and effectiveness data during the 510(k) preparation and review period.

This phase II trial studies the side effects and how well hypofractionated proton beam radiation therapy works in treating patients with prostate cancer that has not spread to nearby lymph nodes or to other parts of the body. Specialized radiation therapy, such as proton beam radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue.
