Veterans Affairs Seamless Phase II/III Randomized Trial of STAndard Systemic theRapy With or Without PET-directed Local Therapy for OligoRecurrenT Prostate Cancer (VA STARPORT)
Summary: This is a prospective, open-label, multi-center seamless phase II to phase III randomized clinical trial designed to compare SST with or without PET-directed local therapy in improving the castration-resistant prostate cancer-free survival (CRPC-free survival) for Veterans with oligometastatic prostate cancer. Oligometastasis will be defined as 1-10 sites of metastatic disease based on the clinica...
A Phase I, Open-label, Multi-center Study of Radiation Dosimetry, Safety, and Tolerability of Extended Lutetium (177Lu) Vipivotide Tetraxetan Treatment in Chemo-naïve Adults With Metastatic Castration-resistant Prostate Cancer
Summary: The purpose of the study is to assess and evaluate dosimetry, safety, and tolerability following administration of up to 12 cycles of (177Lu) vipivotide tetraxetan (also referred to as \[177Lu\]Lu-PSMA-617 or 177Lu-PSMA-617 and hereafter identified as AAA617) in taxane-naïve adult participants with PSMA-positive mCRPC who progressed on a prior ARPI treatment with normal renal function or mild rena...
A Comparison of Orgovyx (Relugolix) vs Eligard (Leuprolide) on Cardiovascular Function and Biomarkers During Standard of Care Combined ADT (Androgen Deprivation Therapy)-Radiation for Prostate Cancer
Summary: This phase II trial compares the effect of relugolix to leuprolide on cardiac function and performance in patients with prostate cancer. Androgen deprivation therapy (ADT) has been a key component for the treatment of advanced prostate cancer for decades. The term androgen deprivation therapy means lowering a man's testosterone. Long-term studies show that ADT may contribute to a detriment to card...
Phase III Study of Local or Systemic Therapy INtensification DIrected by PET in Prostate CAncer Patients With Post-ProstaTEctomy Biochemical Recurrence (INDICATE)
Summary: This phase III trial tests two questions by two separate comparisons of therapies. The first question is whether enhanced therapy (apalutamide in combination with abiraterone + prednisone) added to standard of care (prostate radiation therapy and short term androgen deprivation) is more effective compared to standard of care alone in patients with prostate cancer who experience biochemical recurre...
Estradiol-mediated Inflammation and Central Sensitization in the Pathophysiology of Endometriosis-associated Pelvic Pain
Summary: The purpose of this study is to better understand how hormone suppression with Relugolix Combination-Therapy (CT) affects pelvic pain, inflammation, and pain sensitivity in women with moderate-to-severe endometriosis associated pelvic pain.
A Phase II Study of Sequential Bipolar Androgen Therapy and ZEN-3694 in Sequence With Enzalutamide + ZEN-3694 in Asymptomatic Patients With Metastatic CRPC: The COSMYC Trial (COmbined Suppression of MYC)
Summary: This research is being done to determine if receiving the combination of testosterone and ZEN-3694 followed by the combination of enzalutamide plus ZEN-3694 will decrease the size of tumors in patients with prostate cancer that has become resistant to castration and other therapies. The investigators also want to determine if dosing first with the combination of testosterone and ZEN-3694 may cause...
The Effect of a Novel Combined Hormonal Treatment Containing a GnRH-antagonist for Uterine Fibroids and Endometriosis on Hemostasis Parameters: a Prospective Cohort Study
Summary: Uterine fibroids and endometriosis are two frequent diseases among women of reproductive age. They can be responsible for chronic and/or menstrual pelvic pain and abnormal uterine bleeding. The first-line management of these conditions relies on medical treatment. Hormonal treatment with contraceptive pill can be effective, although up to 30% of patients do not respond to this line of treatment. I...
Phase 2 Randomized Study to Assess Use of Androgen Deprivation to Enrich PSMA Expression and Improve Sensitivity of Staging PSMA PET/CT: The EnrichPSMA Trial
Summary: This phase II trial studies how well a short course of androgen deprivation therapy (ADT) with relugolix works in increasing expression of prostate-specific membrane antigen (PSMA) and improving diagnostic imaging with PSMA positron emission tomography (PET)/computed tomography (CT) in patients with high risk or very high risk prostate cancer. PSMA PET/CT has become the standard of care in imaging...
Parallel Phase III Randomized Trials of Genomic-Risk Stratified Unfavorable Intermediate Risk Prostate Cancer: De-Intensification and Intensification Clinical Trial Evaluation (GUIDANCE)
Summary: This phase III trial uses the Decipher risk score to guide therapy selection. Decipher score is based on the activity of 22 genes in prostate tumor and may predict how likely it is for recurrent prostate cancer to spread (metastasize) to other parts of the body. Decipher score in this study is used for patient selection and the two variations of treatment to be studied: intensification for higher ...
A Phase II Double-Blinded, Placebo-Controlled Trial of PROstate OligoMETastatic RadiotHErapy With or Without ANdrogen Deprivation Therapy in Oligometastatic Prostate Cancer (NRG Promethean)
Summary: This phase II trial compares the usual treatment of radiation therapy alone to using the study drug, relugolix, plus the usual radiation therapy in patients with castration-sensitive prostate cancer that has spread to limited other parts of the body (oligometastatic). Relugolix is in a class of medications called gonadotropin-releasing hormone (GnRH) receptor antagonists. It works by decreasing th...
The SUGAR Study: (SBRT and Ultrashort GnRH Antagonist-Relugolix) for Clinicogenomic Unfavorable Intermediate Risk Prostate Cancer
Summary: The goal of this clinical trial is to measure the toxicity and effectiveness of the following treatments for cFIR/cgUIR prostate cancer patients. Stereotactic body radiotherapy (SBRT) alone or Stereotactic body radiotherapy (SBRT) combined with Ultrashort GNRH Antagonist called Relugolix (an oral drug). Treatments will be randomly assigned to study patients. The main questions it aims to answer ar...
Trial Evaluating the Safety and Efficacy Of MR-Linac-Guided Radiotherapy as Salvage Treatment After External Beam Radiotherapy Recurrence (TUMORNATOR II)
Summary: The purpose of this study is to assess the impact of prostate-specific membrane antigen/positron emission tomography (PSMA/PET)-informed magnetic resonance (MR)-guided radiation therapy on serious toxicity outcomes in patients with biopsy-proven locally radiorecurrent prostate cancer. The primary aim is to evaluate the safety of delivering MR-Linac-guided stereotactic body radiotherapy (SBRT) afte...
