Heat Shock Protein (HSP) 70 to Quantify and Characterize Circulating Tumor Cells

This study investigates the ability of heat shock protein HSP70 to isolate and quantify circulating tumor cells (CTCs) in patients with advanced or metastatic tumors. CTCs will be isolated from peripheral blood before antineoplastic treatment and again after three months. Isolation using HSP70 will be compared with standard CTC isolation by EpCAM. Additionally, imaging parameters of the primary tumor (if available) and metastases will be analysed and correlations between molecular alterations and imaging parameters will be assesed.

225Ac-J591 Plus 177Lu-PSMA-I&T for mCRPC

This is a phase I/II dose-escalation study of 225Ac-J591 administered together with 177Lu-PSMA-I&T (also known as PNT2002). The two study drugs are 225Ac-J591 and 177Lu-PSMA-I&T. Both drugs are designed to deliver radiation to prostate cancer cells; they are known as radionuclide conjugates (radiation linked to antibodies/molecules that recognize prostate cancer cells). The first phase of the study (phase I) will determine the highest dose of the study drug that can be safely given. The second phase of the study (phase II) will determine the effectiveness of the drug combination in patients with prostate cancer.

Start: June 2021

Radiation Hypofractionation Via Extended Versus Accelerated Therapy (HEAT) For Prostate Cancer

Accelerated Hypofractionation Radiotherapy for prostate cancer of 36.25 Gy delivered in 5 fractions will not be inferior to the standard treatment of 70.2 Gy given in 26 fractions with respect to two-year failure defined as a positive biopsy two years post treatment completion or earlier evidence of biochemical or clinical failure.

pTVG-HP DNA Vaccine With or Without pTVG-AR DNA Vaccine and Pembrolizumab in Patients With Castration-Resistant, Metastatic Prostate Cancer

This trial will evaluate the use of one versus two DNA vaccines, delivered concurrently with PD-1 blockade using pembrolizumab followed by treatment with pembrolizumab alone, and delivered over a prolonged period of time (for a maximum of 2 years (32 cycles) or until radiographic progression) on the treatment of castrate-resistant, metastatic prostate cancer. The hypothesis to be tested is that delivering two vaccines with PD-1 blockade will elicit a greater frequency and magnitude of tumor-directed CD8+ T cells, and thereby increase the percentage of patients experiencing objective anti-tumor effect as measured by PSA declines and/or objective radiographic responses. Participants must be 18 years of age or older and can expect to be on treatment for 2 years (32 cycles) and on study for up to 4 years (including 2 years of follow up via phone).

Start: October 2019

Nivolumab and Ipilimumab Treatment in Prostate Cancer With an Immunogenic Signature

The primary objective is to test the following hypothesis: Patients with metastatic castrate resistant prostate cancer that have progressed following at least one line of therapy and have an immunogenic signature will respond to combined PD-1 and CTLA4 inhibition.

Start: February 2018

MRI-Mapped Dose-Escalated Salvage Radiotherapy Post-Prostatectomy: The MAPS Trial

The investigators hypothesize that increasing radiation dose to the functional MRI-defined lesion in the prostate bed will result in an improved initial complete response (reduction in prostate-specific antigen (PSA) to < 0.1 ng/mL), which is related to long-term outcome biochemically. Biomarker expression levels differ in the DCE-MRI enhancing and non-enhancing tumor regions (when applicable). 10-15% of men undergoing RT have free circulating DNA (fcDNA) or tumor cells (CTC) that are related to an adverse treatment outcome. Prostate cancer-related anxiety will be reduced in the MRI targeted SRT arm, because the patients will be aware that the dominant tumor will be targeted with higher radiation dose (compared to those pts who were treated on standard arm prior to its closure).

Start: July 2012

Study of Drug 1 (Enzalutamide) Plus Drug 2 (Relacorilant) for Patients With Prostate Cancer

Stereotactic Ablative Radiotherapy (SABR) of Pelvis and Prostate Targets For High Risk Prostate Cancer

Since high risk prostate cancer requires higher radiation, this study is being done to determine the maximum tolerated dose of radiation to the prostate and pelvic regions. Also to determine the feasibility and safety of each treatment fraction by using cone-beam Computed Tomography(CT) information and high speed Graphics Processing Unit based computation treatment planning systems. We also plan to determine the safety of treatment to the prostate. Health-related quality of life will be measured as part of current clinical practice. Determine the maximum tolerated dose (MTD) or to safely escalate dose to the pelvic nodal using 90 day acute toxicity endpoint Determine feasibility and safety of adaptive real time re-planning of the pelvic nodal region at each treatment fraction by using cone-beam CT (CBCT) information and high speed GPU based computation treatment planning systems Determine the safety and tolerability of 9.5 Gy per fraction in five fractions (47.5 Gy total dose) to the prostate Determine the feasibility and safety of temporal enhanced ultrasound for prostate lesion tracking during radiation therapy To follow tumor related outcomes (i.e. PSA control, progression-free survival (PFS), distant metastasis (DM) free survival, and overall survival (OS) Health-related quality of life (HRQOL) will be measured as part of current clinical practice Patients in each dose cohort will all be treated as a single group for dose escalation. There will be two levels of dose escalation-to prostate lesions and to pelvic lymph node region. Prostate/SV PTV will be treated at a fixed dose of 9.5 Gy per fraction for 5 fractions (47.5 Gy) based on our previous phase I/II study experiences. The starting dose for the dose escalation to the pelvic region PTV will be 4.5 Gy per fraction for 5 fractions (total dose= 22.5 Gy). Subsequent cohorts of patients will receive an additional 0.5 Gy per treatment (total 2.5 Gy per escalation). The starting dose for MRI-visible prostatic lesions will be 10 Gy and subsequent cohorts will receive an additional 0.5Gy per treatment (total of 2.5Gy per escalation).

Search for Predictive Factors of Resistance to Treatment for Metastatic Castration-resistant Prostate Cancer by Studying the Expression of microRNAs

Several drugs are available for metastatic castration resistant prostate cancer such as chemotherapy (docetaxel, cabazitaxel) and novel hormonal agents (abiraterone, enzalutamide), in France. The oncologist has to choose between those two type of treatment, without any biological predictor of efficacy for his patient. It is always difficult to choose knowing that 30 to 50% of patients won't benefit from the treatment chosen. It shows why resistant mechanisms to treatment need to be elucidated. MicroRNA (miR) are short RNA, implicated in messenger ribonucleic acid (mRNA) regulation. Evidence is emerging that miR is implicated in prostate cancer response to treatment. It would be interesting to determine if a miR profile can predict treatment response to chemotherapy and/or to novel hormonal agents.

Development and Evaluation of a Therapeutic Education Intervention in Prostate Cancer Patients Treated With Radical Prostatectomy to Improve Their Sexuality

Prostate cancer is the most common cancer in France (54,000 cases in 2011). About 20,000 radical prostatectomies (PR) per year are performed. Despite the progress of PR over the past 20 years, the rate of erectile dysfunction post PR varies between 30 and 90% and only 16% of operated men recover their pre-treatment erections. There is currently no validated post-prostatectomy rehabilitation protocol. The associations of patients, including the National Association of Prostate Cancer Patients have a very strong demand for treatment of sexual problems after treatment.

Androgen Deprivation Therapy Muscle Protein Metabolism and Blood Glucose

Prostate cancer (PCa) patients receiving androgen deprivation therapy (ADT) (e.g., Zoladex), experience troublesome side effects during and after treatment (e.g., loss of lean body mass (LBM) and increased fat mass). Although the negative effects of ADT on muscle mass are well documented, the cellular effects of ADT on muscle tissue are still largely unknown, and studies investigating the mechanisms are highly warranted. Furthermore, understanding the cellular mechanisms through which ADT negatively influences muscle mass and glucose metabolism is important so that appropriate measures can be taken to counteract muscle wasting and comorbidities during ADT. Thus, PCa patients on ADT (Zoladex), along with non-ADT treated PCa patients serving as controls, will be invited to participate in this study, that aims to investigate the influence of ADT on the basal muscle protein turnover, as well as the responses to strength training. Secondary aims are to investigate between-group differences in blood glucose and insulin responses following a meal).

Use of Indocyanine Green During Pelvic Lymph Node Dissection in Prostate Cancer.

Standard treatment of local or locally advanced prostate cancer is radical prostatectomy (RRP) surgery. During RRP in certain patients extended lymph node dissection (ELND) is recommended. to detect eligible patients for ELND some nomograms based on clinical factors of them is used. The Briganti nomogram is one of them. If the patient has 7% or more probability on Briganti nomogram, then ELND is recommended. But ELND is complicated surgical procedure and may cause labor lost and cost. It is aimed here to show whether the ICG based fluorescence imaging during laparoscopy may yield higher accuracy to detect metastatic LNs than the conventional ELND?

Prostate Cancer - Patient Empowerment Program

Each year over 20,000 men are diagnosed with prostate cancer in Canada with the majority undergoing some form of treatment option. Radical prostatectomy and/or radiation therapy are common procedures that are effective in the treatment of prostate cancer. However, they typically incur both short- and long-term side effects (e.g. urinary incontinence, sexual dysfunction, reduced physical function, etc) that can negatively impact one's quality of life. This study aims to educate and teach pre- (as opposed to most common post-) habilitation - preventive life habits aimed to empower men and address many of the issues faced by men undergoing radical prostatectomy or other active forms of prostate cancer treatments. The investigators hypothesize that daily text and email reminders, in addition to connecting men with other men undergoing similar challenges, will improve participant adherence to the pre-habilitation program. Secondary objectives will assess change in mental health, physical fitness, urological symptoms, state of relaxation, and quality of life parameters before and after the program.
