Filter by:The purpose of this study is to test whether acupuncture can improve nocturia in prostate cancer survivors. This is the first time acupuncture is being studied for nocturia in prostate cancer survivors. Researchers will see if acupuncture is a practical treatment option for prostate cancer survivors with nocturia. The study will also look at the effect acupuncture has on nocturia and other symptoms prostate cancer survivors experience such as insomnia, hot flashes, anxiety, depression, tiredness (fatigue), sexual dysfunction, and cognitive (mental) difficulties.
PSMA-PET/CT response measurements after LHRH agonist and upfront enzalutamide therapy in men diagnosed with de novo metastasized hormonal sensitive prostate cancer.
This is an open-label, multi-site study of apalutamide with carotuximab in patients who have progressed on androgen receptor signaling inhibitor (ARSI) therapy. This study will begin with a safety assessment in the first 10 subjects (part 1: Safety Lead-in). If the combination is deemed safe, the trial will proceed to the Phase II stage. The purpose of this study is to compare progression free survival (PFS) between patients receiving apalutamide and apalutamide + carotuximab using Response Evaluation Criteria in Solid Tumors (RECIST 1.1) and Prostate Cancer Working Group 3. The secondary objectives are to describe adverse events related to the intervention, overall response rate (ORR), proportion of patients resistant to apalutamide that benefit from the addition of carotuximab, and to determine the ORR, radiographic PFS, and biochemical PFS in the overall population.
The goal of this study is to establish the value of Circulating Tumour Cell (CTC) positivity in predicting post-RP treatment failure, including BCR and new lesions detected by cancer imaging. We plan to recruit participants who will undergo Radical Prostatectomy (RP). Participants will have their blood samples taken just before surgery and 3 months after the surgery to test for CTCs. Then participants will be followed-up for cancer progression information at 3 month intervals for the first year then yearly intervals after that. Their PSA will be observed over time.
This phase I clinical trial is to evaluate the safety of Prodencel (an autologous dendritic cell therapeutic tumor vaccine.) in patients with metastatic castration-resistant prostate cancer (mCRPC).
This study will establish the preferred dose of lisinopril in men with non-metastatic prostate cancer undergoing radiation treatment. This study will also evaluate the effect of lisinopril on urinary symptoms and the impact of lisinopril on biomarkers and their association with urinary symptoms.
Researchers are looking for a better way to treat men who have biochemically recurrent hormone-naïve prostate cancer. Hormone-naïve prostate cancer is a prostate cancer that has not yet been treated with hormonal therapy including androgen deprivation therapy (ADT). Biochemically recurrence (BCR) means that patients who received local treatment (surgery or radiation therapy) for prostate cancer now present with a rise in the blood level of a specific protein called PSA (prostate-specific antigen) but no detectable cancer or cancer spreading after a treatment that aimed to cure their prostate cancer (e.g. surgery and radiation). This may mean that the cancer has come back as the PSA level can be taken as a marker for prostate cancer development. Although men with BCR may not have symptoms for many years, proper treatment for BCR is important as the cancer may spread to other parts of the body in 7-8 years. In prostate cancer patients, male sex hormones like testosterone (also called androgens) can sometimes help the cancer spread and grow. To reduce androgen levels in these patients, androgen deprivation therapy (ADT) is often used. Second generation androgen receptor inhibitors including Darolutamide and Enzalutamide are available for the treatment of prostate cancer in addition to ADT. These inhibitors work by blocking androgen receptors and preventing it from attaching to proteins in cancer cells in the prostate. It is already known that men with prostate cancer benefit from these treatments. But besides benefits, Darolutamide and Enzalutamide are not without side effects. Clinical studies have shown that treatment with Enzalutamide increase testosterone level in serum, probably because it can pass blood brain barrier and goes into the central nervous system (CNS). The increased testosterone levels are thought to cause some specific side effects including so called feminizing side effects like overdevelopment of the breast tissue in men, and breast tenderness. Darolutamide has a distinct chemical structure and reduced ability to enter the CNS compared with Enzalutamide. That means that Darolutamide potentially leads to fewer and less severe side effects than Enzalutamide. In this study researchers will collect more data to learn to what extent Darolutamide affects serum testosterone levels in men with BCR in hormone-naïve prostate cancer. This study will consist of 2 stages. In stage 1 (also called lead-in phase) all participants will take Darolutamide by mouth twice a day. The study team will monitor and measure testosterone levels in the blood after: - 12 weeks - 24 weeks and - 52 weeks of treatment. The second stage (also called randomized phase) is conditional and depends on the results from the stage 1. It will be conducted if after 24 weeks of treatment with Darolutamide in stage 1: - a mean change in blood testosterone levels is below 45% and - if the feminizing side effects (including overdevelopment of the breast tissue in men, and breast tenderness) will occur less frequently than previously reported. In the second stage of this study all participants will be randomly (by chance) assigned into two treatment groups, taking either Darolutamide twice daily or Enzalutamide once daily by mouth for a minimum of 12 and a maximum of 52 weeks. During both stages of this study the study team will: - do physical examinations - take blood and urine samples - examine heart health using ECG - examine heart and lung health using CPET - check bone density using x-ray scan (DEXA) - check vital signs - check if the participants' cancer has grown and/or spread using CT (computed tomography) or MRI (magnetic resonance imaging) and, if needed, bone scan - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. The study participants who receive Darolutamide in stage 2 can continue to receive their treatments as long as they benefit from the treatment. The participants from the Enzalutamide group can also switch to treatment with Darolutamide after finishing stage 2. The study team will continue to check the participants' health and collect information about medical problems that might be related to Darolutamide until up to 30 days of last dose for those participants who continue on treatment with Darolutamide.
A two-centre prospective cohort phase III study of 18F-PSMA-1007 PET/CT imaging in specific patient populations: 1. Adults patients (≥18 years old) with a history of radical prostatectomy for treatment of prostate cancer, and a serum prostate specific antigen (PSA) ≥ 0.2 mcg/L 2. Adult patients with a history of radiotherapy, cryotherapy, or brachytherapy for treatment of prostate cancer, and a serum PSA progressively rising to ≥ 2 mcg/L (minimum two samples) OR a serum PSA doubling time of < 9 months 3. Adult patients with a history of biopsy-proven prostate cancer and high-risk features for metastatic disease prior to treatment with radical prostatectomy, radiotherapy, cryotherapy, or brachytherapy. High-risk features include a Gleason score ≥ 7, serum PSA ≥ 20 mcg/L, OR minimum clinical T-stage T2c 4. Adult patients who do not meet criteria 1-3 but in whom a 18F-PDAM-1007 PET/CT scan is expected to provide clinical benefit as determined by a Urologist, Radiation Oncologist, Medical Oncologist, or Nuclear Medicine physician (licensed in Alberta) The safety of the investigational 18F-PSMA-1007 tracer will be evaluated in 3 ways: 1. The participant will be screened for adverse effects immediately post-injection 2. The participant will be screened for adverse effects immediately after the scan (approximately 2.5 hours after tracer injection) 3. The participant will be provided an information sheet and contact information for self-reporting of any delayed adverse events (1-7 days post injection) The incidence of and activity of non-specific bone lesions will be quantified and evaluated as follows: 1. All lesions categorized as non-specific bone lesions (PSMA-1007 SUVmax > 2.5 but no corresponding lesion on CT) will be recorded 2. The SUVmax and anatomic location will be recorded for each lesion (max 5 per participant) 3. Recorded lesions will be evaluated a minimum of 1 year post-scan to determine whether they are benign or malignant based on previously published reference standard criteria (Arnfield et al., 2021) 4. Equivocal lesions will be considered unevaluable and will be excluded from assessment of accuracy
This study is a first-in-human, Phase 1, open-label, multicenter study to assess the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and the preliminary efficacy of JANX007 administered as a single agent in adults with metastatic castration-resistant prostate cancer (mCRPC).
Metformin is used widely in the treatment of type 2 diabetes. It has off-label indications for use in the prevention of diabetes and in hyperinsulinar obesity. In medical practices, the implementation of metformin for these off-label indications is variable, often at the level of the provider. Multiple retrospective investigations have also shown a clinical benefit in men with prostate cancer who are incidentally treated with metformin. This pragmatic study will test the feasibility of enrolling patients who have glucose intolerance (as defined by HbA1c of 5.7-6.4%) and/or who have increased BMI (BMI greater than or equal to 25 kg/m2) to a randomized pragmatic study of metformin plus lifestyle modification information versus lifestyle modification information only. For purposes of the scope of this project and the study's feasibility, this will be implemented in a group of prostate cancer patients, who may have additional benefits from metformin.
