Using Rectal Hydrogel Spacer for Salvage SABR in Prostate Cancer
Prostate CancerThere are several single institutional series that have reported their experience with salvage radiotherapy options that include EBRT, LDR and HDR brachytherapy. Gastrointestinal (GI) toxicity with salvage radiotherapy range between14-58%, respectively for patients undergoing re-irradiation. There is a concern for an increased risk of fistula development in these patients who receive second course of radiation. Hypofractionation using SABR has been utilized in the re-irradiation setting for prostate cancer with good tumor control and toxicity outcomes. In order to decrease the rectal toxicity, dose to the rectum should be kept as low as possible. Several techniques can be used to achieve this: tighter dosimetric dose painting, better patient or organ immobilization or use of a biodegradable gel. The Investigators ropose a phase I study to assess placement of a hydrogel spacer between the prostate and rectum, in an effort to decrease toxicity and improve patient's bowel quality of life.
An Open-label Study Comparing Lutetium (177Lu) Vipivotide Tetraxetan Versus Observation in PSMA...
Oligometastatic Prostate Cancer (OMPC)The purpose of this study is to evaluate the efficacy and safety of lutetium (177Lu) vipivotide tetraxetan (AAA617) in participants with oligometastatic prostate cancer (OMPC) progressing after definitive therapy to their primary tumor. The data generated from this study will provide evidence for the treatment of AAA617 in early-stage prostate cancer patients to control recurrent tumor from progressing to fatal metastatic disease while preserving quality of life by delaying treatment with androgen deprivation therapy (ADT).
This Study is Evaluating a New Radiation Treatment Technique for Patients Who Have Had Prostate...
Recurrent Prostate Cancer After SurgeryThere is significant, proven use of radiation for recurrent prostate cancer after surgical resection. This treatment typically is delivered over seven and a half weeks of daily treatments, presenting a burden to patients and the health care system. Stereotactic body radiation (SBRT) is a radiation technique in which large doses are delivered over a short period of time. To date there is extremely limited evidence in SBRT for recurrent prostate cancer after surgery, with a significantly growing body of evidence for primary SBRT treatment of prostate cancer in men who opt for non-surgical upfront treatment. Additionally, advances in imaging have allowed better detection of the site of recurrence, and novel artificial intelligence aided daily-adaptive radiation therapy have allowed more precise delivery of radiation doses. This study seeks to evaluate the role of Daily-Adaptive with AI-assisted SBRT in the post operative setting utilizing Ethos Plan Adaptive technology in attempt to maintain control and minimize side effects.
Prostate Oligometastatic Cancer Management Driven by Disease Biology et/or Immunoactivity (PROMETEO)...
Oligometastatic Prostate CancerCurrently, despite the advent of next-generation imaging has improved the detection of Oligometastatic prostate cancer (OMPC), prognostic biomarkers able to stratify patients and monitor treatment response are lacking and urgently needed. Mounting evidence suggests that molecular profiling of the disease and host immune activity evaluation can reveal OMPC heterogeneity and address the above unmet clinical need. This study aims at combining the analysis of several biomarkers to improve the prognostic stratification of OMPC patients
A Multi-Center, Prospective, Observational Study of Patients Being Treated With ORGOVYX
Prostate CancerThis is a multi-center, prospective, observational study of patients being treated with ORGOVYX. The goal of this study is to generate real-world evidence about the safety and effectiveness of ORGOVYX in patients with prostate cancer in routine clinical care and the clinical course during treatment with and following cessation of ORGOVYX.
Correlation Between Seminal Vesicle Size and Duration of Sexual Abstinence
Suspected Prostate CancerThe seminal vesicles (SV) are glands that open into the prostatic urethra and secrete seminal fluid, which makes up 50 to 80% of semen. They play an essential role in the male reproductive function. In adults, the size of a seminal vesicle varies from one individual to another. On average, it is 5 to 6 cm long, 1.5 cm wide and 0.5 cm thick. It has a close anatomical relationship with Walsh's vascular-nervous pedicle, which extends the sacro-genital-pubic blades, and is responsible for erection. The reference treatment for localized prostate cancer can consist of two alternatives: either intensity-modulated pelvic radiotherapy with treatment of the entire prostate volume and VS, or surgical removal of the vesiculo-prostatic block in monobloc. It is therefore always extended to the VS. Magnetic resonance imaging (MRI) is now routinely performed for the initial workup of prostate cancer, with a diagnostic and prognostic role, as invasion of the VS by cancer is recognized as a poor prognostic factor. Some radiology centers recommend 3 days of sexual abstinence to allow a proper seminal vesicle study. Various factors, such as serum testosterone levels, autosomal dominant polycystic kidney disease, smoking, and certain drugs such as SILODOSINE, have been identified as factors that can independently vary seminal vesicle size. The duration of sexual abstinence since the last ejaculation also appears to be correlated with seminal vesicle volume. Two recent studies found a correlation between the duration of sexual abstinence and seminal vesicle volume measured on MRI in a young population (median age 35.9 and 46.45 years). This population is not superimposable to that of patients managed for prostate cancer whose average age at diagnosis is 70 years. However, the control and knowledge of the volume of VS, in this specific population, could have an interest in the treatment of prostate cancer: In case of pelvic radiotherapy in order to limit the volume of the organ to be irradiated, the toxicity induced to the adjacent organs being directly associated to the delivered dose. In case of radical vesiculo-prostatectomy, by surgical way, the lateral dissection of the vasculo-nerveous bands is made more difficult in case of voluminous seminal vesicles with an increased risk of nerve damage. Investigators hypothesize that the volume of the VS is correlated with the duration of abstinence. Thus, evacuation of seminal fluid by ejaculation at a defined time before curative treatment of prostate cancer, could improve the functional results of pelvic radiotherapy or surgery.
Mechanisms, Predictors, and Social Determinants of Cardiotoxicity in Prostate Cancer
Prostate CancerCardiotoxicity2 moreThis is an observational study for patients with prostate cancer that will be treated with Androgen Deprivation Therapy. The study will help the investigators learn more about how these medications affect the heart and how those effects relate to patients' medical history and social determinants of health (such as race, gender identity, education, occupation, access to health services and economic resources). Patients on this study will have echocardiograms, blood draws, and answer questions about their symptoms and activity level. Patients will be followed on this study for up to 5 years.
ONC-392 Plus Lutetium Lu 177 Vipivotide Tetraxetan in Patients With mCRPC
Metastatic Castration-resistant Prostate CancerThe goal of this clinical trial is to examine the safety and efficacy of ONC-392 in combination with lutetium Lu 177 vipivotide tetraxetan in metastatic castration resistant prostate cancer patient who have disease progressed on androgen receptor pathway inhibition. The main questions it aims to answer are (1) whether it is safe to combine ONC-392 with lutetium Lu 177 vipivotide tetraxetan, (2) whether the combination increases the radiographic progression free survival (rPFS). Participants will be randomized to two arms in 2:1 ratio. In experimental arm, they will be given ONC-392 10 mg/kg IV infusion, once every 4 weeks for up to 13 cycles or approximately one year, together with lutetium Lu 177 vipivotide tetraxetan 7.4 GBq IV, once every 6 weeks for up to 6 cycles. In active control arm, they will be given standard of care treatment with lutetium Lu 177 vipivotide tetraxetan 7.4 GBq IV, once every 6 weeks for up to 6 cycles.
