NCT00936390
RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells and shrink tumors. Androgens can cause the growth of prostate cancer cells. Androgen-deprivation therapy may lessen the amount of androgens made by the body. It is not yet known whether radiation therapy is more effective with or without androgen-deprivation therapy in treating patients with prostate cancer. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared with radiation therapy given together with androgen-deprivation therapy in treating patients with prostate cancer.
NCT06235099
This is a prospective, open-label Phase 3 study to evaluate copper Cu 64 PSMA I\&T injection for PET/CT imaging in patients with recurrent prostate cancer after radical prostatectomy or radiation therapy.
NCT02861573
The purpose of this study is to assess the safety and efficacy of pembrolizumab (MK-3475) combination therapy in participants with metastatic castration resistant prostate cancer (mCRPC). There will be ten cohorts in this study: Cohort A will receive pembrolizumab + olaparib, Cohort B will receive pembrolizumab + docetaxel + prednisone, Cohort C will receive pembrolizumab + enzalutamide, Cohort D will receive pembrolizumab + abiraterone + prednisone Cohort E will receive pembrolizumab+lenvatinib, Cohort F will receive pembrolizumab+lenvatinib, Cohort G will receive pembrolizumab/vibostolimab coformulation (MK-7684A), Cohort H will receive pembrolizumab/vibostolimab coformulation, Cohort I will receive pembrolizumab+carboplatin+etoposide in Arm 1 and carboplatin+etoposide in Arm 2 and Cohort J will receive belzutifan in Arm1 and Pembrolizumab+belzutifan in Arm 2. Outcome measures will be assessed individually for each cohort.
NCT04848337
Eligible patients will be treated with the combination of lenvatinib and pembrolizumab. A cycle equals 21 days and therapy will continue until radiographic progression, intolerable toxicity, or patient/physician wishes to discontinue protocol therapy. A maximum of 35 cycles may be administered. On Day 1, when both pembrolizumab and lenvatinib are administered, patients should take the lenvatinib per their normal routine.
NCT05334069
This study collects blood and tissue samples from patients with cancer and without cancer to evaluate tests for early cancer detection. Collecting and storing samples of blood and tissue from patients with and without cancer to study in the laboratory may help researchers develop tests for the early detection of cancers.
NCT05884398
The purpose of the study is to determine if the intermittent use of androgen-deprivation therapy (ADT) in participants with metastatic castrate-sensitive prostate cancer (mCSPC) who reached a prostate-specific antigen (PSA) level \< 0.2 nanograms/millilitres (ng/mL) after 6 months of treatment with apalutamide and ADT combination therapy provides non-inferior radiographic progression-free survival (rPFS) and a reduced burden of hot flashes measured as 18-month percent change in severity adjusted hot flash score.
NCT00063882
RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Interstitial brachytherapy uses radioactive material placed directly into or near a tumor to kill tumor cells. Combining interstitial brachytherapy with external-beam radiation therapy may kill more tumor cells. It is not yet known whether interstitial brachytherapy is more effective with or without external-beam radiation therapy in treating prostate cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of interstitial brachytherapy with or without external-beam radiation therapy in treating patients who have prostate cancer.
NCT06379217
The purpose of this study is to evaluate the change in the expression of treatment targets on the surface of tumor cells (Prostate Specific Membrane Antigen (PSMA), Somatostatin Receptor 2 (SSTR2), and Gastrin Releasing Peptide Receptor (GRPR) between the baseline and following targeted radioligand therapy (RLT). Study will use radioligand imaging (RLI) to determine predominantly expressed target on the surface of tumor cells. Based on predominant expression of target, corresponding RLT targeting PSMA, SSTR2, or GRPR RLT will be given for up to 6 cycles every 6 weeks as intravenous (i.v.) injection in participants with metastatic neuroendocrine prostate cancer (mNEPC). Study is planning to enroll approximately 20 participants in \[177Lu\]Lu-PSMA-617 treatment arm, approximately 3 participants in \[177Lu\]Lu-NeoB treatment arm, and approximately 13 participants in \[177Lu\]Lu-DOTA-TATE treatment arm.
NCT04221542
The overall aim of the trial is to evaluate the safety, tolerability, and pharmacokinetics (PK) of AMG 509 (monotherapy and in combination with abiraterone acetate and enzalutamide) and to evaluate preliminary efficacy. As of Protocol Amendment 10 (09 July 2025), only Parts 4A expansion, 6, and 7 are open to accrual.
NCT06056791
This is an open-label, phase I/IIa dose escalation and expansion study of INKmune in men with mCRPC. INKmune is administered to patients intravenously over three doses, at least one-week apart. The study will consist of two stages.
NCT01314118
The purpose of this study is to show that abiraterone acetate plus prednisone added to the current standard of care, gonadotropin-releasing hormone (GnRH) decreases prostate specific antigen (PSA) and prolongs the time until it is evident that the cancer has grown. Additionally, safety information about abiraterone acetate in combination with prednisone will be collected. This will include looking at what side effects occur, how often they occur, and for how long they last.
NCT06991556
This Phase II study aims to evaluate efficacy and safety of the combination of JSB462 (also known as luxdegalutamide) at 100 mg and 300 mg once a day (QD) doses + abiraterone compared with an androgen receptor pathway inhibitor (ARPI, abiraterone or enzalutamide) in participants with metastatic Hormone Sensitive Prostate Cancer (mHSPC) and to select the recommended dose of the combination for phase III. Towards that end, the totality of the efficacy, safety, tolerability and PK data from participants randomized in the study will be evaluated
NCT04489719
This study investigates how well radium-223 works in treating patients with castration-resistant prostate cancer than has spread to the bones (bone metastases). Prostate cancer is the most common cancer in men and the second leading cause of cancer death. Furthermore, many men with notably advanced disease have been found to have abnormalities in DNA repair. The purpose of this research is to study the role of a DNA repair pathway in prostate cancer, specifically in response to administration of radium-223, an FDA-approved drug known to cause DNA damage to cancerous cells. Understanding how defects in the DNA repair pathway affects radium-223 treatment of prostate, may help doctors help plan effective treatment in future patients.
