A Study of Abiraterone Acetate Plus Prednisone With or Without Abemaciclib (LY2835219) in Participants...
Prostate CancerThis study is being done to see how safe and effective abemaciclib is when given together with abiraterone acetate plus prednisone in participants with metastatic castration resistant prostate cancer. Prednisolone may be used instead of prednisone per local regulation.
Study of Pembrolizumab (MK-3475) Plus Olaparib Versus Abiraterone Acetate or Enzalutamide in Metastatic...
Prostatic NeoplasmsThe purpose of this study is to assess the efficacy and safety of the combination of the polyadenosine 5'-diphosphoribose poly (ADP-ribose) polymerase (PARP) inhibitor olaparib and pembrolizumab in the treatment of participants with mCRPC who have failed to respond to either abiraterone acetate or enzalutamide (but not both) and to chemotherapy. The primary study hypotheses are that the combination of pembrolizumab plus olaparib is superior to abiraterone acetate or enzalutamide with respect to: Overall Survival (OS) and Radiographic progression-free survival (rPFS) per Prostate Cancer Working Group (PCWG)-modified Response Evaluation Criteria in Solid Tumors Version 1.1 as assessed by blinded independent central review (BICR) As of Amendment 06, the Data Monitoring Committee (DMC) is no longer applicable. Participants still on treatment may have the option to continue receiving study intervention or SOC if they are deriving clinical benefit, until criteria for discontinuation are met. Participants who are still on study treatment and deriving clinical benefit will no longer have tumor response assessments by BICR. However, local tumor imaging assessments should continue per SOC schedule. In addition, ePRO assessments will no longer be performed and biomarker samples will no longer be collected.
177Lu-PSMA-617 and Pembrolizumab in Treating Patients With Metastatic Castration-Resistant Prostate...
Castration Levels of TestosteroneCastration-Resistant Prostate Carcinoma5 moreThis phase Ib trial studies the dose and schedule of 177Lu-PSMA-617 and pembrolizumab in treating patients with castration-resistant prostate cancer that has spread to other places in the body. 177Lu-PSMA-617 carries a radioactive component which attached to the prostate specific membrane antigen (PSMA) receptor found on tumor cells. Its radiation component destroys the tumor cell. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body?s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving 177Lu-PSMA-617 and pembrolizumab may work better at treating prostate cancer.
Study on Olaparib Plus Abiraterone as First-line Therapy in Men With Metastatic Castration-resistant...
Metastatic Castration-resistant Prostate CancerThe purpose of this study is to evaluate the efficacy and safety (including evaluating side effects) of combination of olaparib and abiraterone versus placebo and abiraterone in patients with metastatic castration-resistant prostate cancer (mCRPC) who have received no prior cytotoxic chemotherapy or new hormonal agents (NHAs) at metastatic castration-resistant prostate cancer (mCRPC) stage.
Biomarker Analysis of Castration-resistant Prostate Cancer Undergoing Treatment With Docetaxel Followed...
Prostate CancerCastration-resistant Prostate CancerThis is a prospective biomarker study of patients with metastatic castration-resistant prostate cancer (mCRPC) undergoing sequential treatment with docetaxel and enzalutamide. The participants will undergo serial pre- and post-therapy blood collection for biomarker analysis as part of the primary objective of the study. The primary goal of this study is to evaluate the association of the AR-V7 status and androgen receptor (AR) gene alterations with PSA response to docetaxel and enzalutamide.
A Trial of Immunotherapy Strategies in Metastatic Hormone-sensitive Prostate Cancer
Metastatic Hormone-sensitive Prostate CancerMetastatic prostate cancer is an incurable disease that typically spreads beyond the prostate. The standard of care is to systemically treat the disease with androgen deprivation therapy (ADT). However, the disease progresses in virtually all patients to the state of castration resistant prostate cancer (CRPC), with a median time to progression of 24 months. Patients with high volume disease (with either visceral metastasis and/or bone metastasis) exhibit a worse prognosis, with a median clinical progression of 14 months. Recently, the CHAARTED and STAMPEDE studies demonstrated that the combination of Docetaxel (chemotherapy) and ADT delayed the clinical progression and improved the survival a median of 14 months (17 for high volume patients). Nevertheless, the prognosis of patients with high volume metastatic disease continues to be poor. Meanwhile the immunotherapy, the use of antibodies that recognize tumoral cells and promote the immune system activity against the cancer, has emerged as a very useful option in many cancers. Among others, the antibodies Nivolumab and Ipilimumab have been approved for the treatment of multiple types of cancer. In this context, SOGUG (Spanish Oncology Genitourinary Group) has designed this new study "PROSTRATEGY" with the objective of evaluating whether the addition of immunotherapy to chemotherapy and ADT improves the prognosis and survival of patients with high volume metastatic hormone-sensitive prostate cancer.
PSCA-CAR T Cells in Treating Patients With PSCA+ Metastatic Castration Resistant Prostate Cancer...
Castration-Resistant Prostate CarcinomaMetastatic Prostate Carcinoma3 moreThis phase I trial studies side effects and best dose of PSCA-chimeric antigen receptor (CAR) T cells in treating patients with prostate stem cell antigen positive (PSCA+) castration resistant prostate cancer that has spread to other places in the body (metastatic). PSCA-CAR T cells are immune cells that have been engineered in the laboratory to kill tumor cells. This is done by using a virus to insert a piece of deoxyribonucleic acid (DNA) into the immune cells that allows them to recognize prostate tumor cells. It is not yet known how well PSCA-CAR T cells works in killing tumor cells in patients with metastatic castration resistant prostate cancer.
Stereotactic Body Radiation Therapy in Treating Patients With Localized Prostate Cancer That Have...
PSA Level Greater Than 0.03PSA Progression3 moreThis phase II trial studies how well stereotactic body radiation therapy works in treating patients with prostate cancer that has not spread to other parts of the body and have undergone surgery. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue.
A Study of Androgen Receptor (AR) Antagonist Apalutamide in Chinese Participants With Metastatic...
Prostatic NeoplasmsThe purpose of this study is to evaluate pharmacokinetics (PK) following a single dose and multiple dose treatment and the safety of apalutamide in Chinese participants with metastatic castration resistant prostate cancer (mCRPC) at dose of 240 milligram (mg).
Biodistribution/Reproducibility Ga-68 PSMA-HBED-CC
Prostatic NeoplasmsThe purpose of this Radioactive Drug Research Committee (RDRC) study is to collect initial data regarding biodistribution, reproducibility, and dosimetry for the radiotracer Ga-68 PSMA-HBED-CC, an agent which may be useful for the early detection of metastatic prostate cancer. Investigators will use a test and re-test design in all patients to determine reproducibility of lesion detection and signal intensity, and will include dynamic imaging in some patients for the purposes of dosimetry. Patients with known metastatic prostate cancer will be recruited and imaged on two occasions within the course of 15 days.
