Filter by:This randomized, controlled, single center clinical trial aims to evaluate the efficacy and safety of Androgen Deprivation Therapy Combined with Docetaxel for High Risk Prostate Cancer with a six-month treatment cycle.
This phase I study will assess the toxicity profile and efficacy of SBRT (Stereotactic body radiotherapy) in patients with localized prostate cancer who are considered candidates for post-prostatectomy radiation.
Ga-68 PSMA-11 PET/CT is known as useful method for localizing recurred tumor lesions in prostate cancer patients with biochemical recurrence [elevated serum prostate specific antigen (PSA) after radical prostatectomy]. The recent digital PET/CT which is known to show better resolution and sensitivity than analogue PET/CT may have better performance for detecting early small recurred tumor lesions. This study is intended to compare the diagnostic performance (detection rate and positive predictive value) of Ga-68 PSMA-11 PET/CT using analogue PET/CT scanner and digital PET/CT scanner in same patients who had biochemical recurrence of prostate cancer.
This trial is testing whether molecularly targeted oral medications called talazoparib and tazemetostat can be safely combined for the treatment of prostate cancer, and whether the combination is effective in shrinking or preventing the growth of metastatic prostate cancer. The names of the study drugs involved in this study are: - Talazoparib - Tazemetostat
As the most common carcinoma in men, prostate cancer is a significant tumor entity in oncology. In addition to the surgical approach, definitive radiotherapy is an equivalent therapy alternative in the non-metastatic primary situation. However, radiotherapy usually stretches over a period of several weeks (7 to 8 weeks) during which the patient receives irradiation on a daily basis. For this reason and for radiobiological considerations the total treatment time is increasingly shortened. It has been shown in several randomized phase III studies that shorting radiotherapy to about 4 weeks by increasing the single dose (so-called hypofractionation) is possible. Meanwhile there is also more data on extreme hypofractionation (max. 10 radiation sessions) available, however often times, extensive preparations are necessary (such as the invasive introduction of markers into the prostate). The current, prospective, non-randomized, multicentric, Phase II SMILE study is now testing whether the MRI-guided radiotherapy with a greatly shortened radiotherapy of the prostate over 5 radiation sessions is possible and safe.
This is a single arm phase II study of image-guided pencil beam scanning proton SBRT (40Gy RBE in 5 fractions delivered every other day) for patients with low- and intermediate-risk prostate cancer. The primary aim is to assess GU/GI toxicity of proton SBRT and compare this to historic outcomes associated with photon-based prostate SBRT. The primary endpoint is 2-year grade 3+ GU/GI toxicity free rate by CTCAE v5.0, which is expected to be ≥95%. Toxicity will be evaluated by the treating radiation oncologist at least once during SBRT, then following SBRT at 1, 3, 6, 12, 18, and 24 months. The treatment will be considered safe if grade 3 or higher GU/GI toxicity free rate at 2 years is >85% (95% rate expected with a 10% non-inferiority margin). The accrual goal is 61 patients over 3 years. To ensure that unexpected significant toxicity is identified, all grade 3 or higher toxicities will be reported to the study PI and the trial will stop accruing if at any point 4 or more patients experience a grade 3 or higher toxicity after completing SBRT. This is felt to be conservative given the vast experience with photon SBRT at this dose with an expected G3+ toxicity of ~5%. Secondary objectives are to examine patient-reported urinary, gastrointestinal, sexual, and financial outcomes using IPSS, EPIC-26, and COST questionnaires at the same follow-up timepoints as above. Baseline measures of these domains will be obtained prior to treatment as well. Clinical outcomes will also be evaluated with PSA measured at each follow-up, as well as prostate MRI and biopsies at 2 years. Patients will be followed for at least 2 years to determine rates of PSA relapse, salvage treatment, development of metastases, death from prostate cancer, and overall survival. A dosimetric comparison will be performed where each patient will be planned for proton and photon SBRT to determine possible advantages of proton SBRT.
This is a preliminary evaluation of a radiotracer's biodistribution in human subjects. It is a prospective, single-centre, open-label, single group assignment interventional study. Prostate cancer is very common, and PSMA imaging is currently the most accurate means of localizing these tumours. The goal is to evaluate the biodistribution and safety of [68Ga]HTK03149 PET/CT for prostate cancer imaging.
The purpose of the study is to evaluate the safety and efficacy of talazoparib in combination with enzalutamide compared with placebo in combination with enzalutamide in participants with DDR-deficient mCSPC.
This study collects urine from male patients seen at the urology clinic to detect prostate cancer cells, shed in voided urine, using the optical imaging method developed in the laboratory, which targets certain biomarkers expressed on prostate cancer cells. The information learned from this study may allow researchers develop a simple diagnostic test for the management of those patients who have elevated prostate specific antigen (PSA) and are suspected to have prostate cancer. It may also help researchers understand the genetic risk factors associated with prostate cancer.
This intervention includes the introduction of the Prostate Cancer Working Group (PCWG )Smart PSA Screening Guidelines and implementation of patient navigation/ care coordination for men with elevated PSA (>4.0 ng/mL). The guidelines include: 1. What age to start? 2. How often to repeat screening? 3. What age to stop? 4. What PSA threshold should trigger a biopsy referral?
