Active clinical trials for "Prostatic Neoplasms"

This is a prospective, interventional pilot study to evaluate the feasibility of randomizing patients diagnosed with prostate cancer to different treatment schemes according to their risk. Patients with a diagnosis of prostate adenocarcinoma (confirmed by biopsy), without signs of metastasis outside the pelvis in the staging study and without prior radiotherapy (RT) to the pelvic region will be recruited. The definition of risk group from the international guide National Comprehensive Cancer Network will be used. Low risk Favorable intermediate risk Unfavorable intermediate risk High risk The use of hormonal blocking will be at the discretion of each treating physician. The radiotherapy simulation will be carried out according to the institutional protocol for the treatment of prostate cancer. According to the risk group of the patients, the following randomization will be carried out: Low / intermediate favorable risk: Patients will be randomized to receive SBRT to prostate 36.25 Gy in 5 fractions, alternate days or weekly, with VMAT (technique and 6 Mega-voltage (MV) X-rays vs to SBRT to prostate 26 Gy in 2 fractions, 1 weekly fraction, with VMAT technique and 6 Mv X-rays. The volumes to be treated, ¨Clinical target volume¨ (CTV) will be defined as the prostate, according to the consensus of the Radiation Therapy Oncology Group (RTOG). Intermediate unfavorable risk and high risk: Patients will be randomized to receive SBRT to the prostate and seminal vesicles, 36.25 Gy in 5 fractions, alternate days or weekly, with VMAT technique and 6 MV X-rays vs SBRT to pelvis scheme of 25 Gy in 5 fractions with simultaneous integrated boost up to 36.25 to the prostate and seminal vesicles, with the same technique. Patients with positive pelvic node: Will be randomized to moderate hypofractionated RT , completing a dose of 44 Gy in 20 fractions to the pelvis with a simultaneous integrated boost up to 54-60 Gy in 20 fractions to metastatic lymphadenopathy and prostate with seminal vesicles, completing 60 Gy to prostate and seminal vesicles or to ultra hypofractionated RT to the prostate and macroscopic lymphadenopathy to 35 and 30-35 Gy respectively and 25 Gy in 5 fractions to the elective nodal areas.

OVM-200 will be tested in humans for the first time in Study OVM-200-100. Up to 52 patients aged 18-75 with prostate, lung or ovarian cancer will be enrolled in the Study to find out if OVM-200 is safe to continue studying it in patients with cancer. The Study consists of 2 parts: a dose escalation part and a dose expansion part. In the dose escalation part, up to 4 increasing doses of OVM-200 will be evaluated in small groups of cancer patients to find the recommended dose for the expansion part. The recommended dose of OVM-200 will then be given to cancer patients in the dose expansion part to confirm safety and understand how effective it is against their disease and if there are any side effects. Patients who agree to participate in the Study and pass screening will receive 3 doses of OVM-200 in total at 2-week intervals as an injection under the skin. After completing treatment with OVM-200 patients will be followed up for side effects and to monitor changes in their cancer. Patients will stay on the Study for about 6 months in total during which they will have 10 hospital visits. The Study will run at around 5 sites in the UK.

The study is being conducted to evaluate the efficacy and safety of SHR3680 plus androgen deprivation therapy (ADT) vs. placebo plus ADT in patients with high-risk localized or locally advanced prostate cancer using pathologic complete response (pCR) rate and metastasis-free survival (MFS).

Single-arm phase II trial of 70 men with low- or intermediate-risk prostate cancer receiving magnetic resonance guided adaptive radiotherapy (MRgRT) in 5 fractions of 7.25 Gy, additionally sparing the neurovascular bundles, the internal pudendal arteries, the corpora cavernosa, and the penile bulb for erectile function preservation.

Random assignment between SBRT and conventionally fractionated boost following HDR brachytherapy for prostate cancer.

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Androgens can stimulate the growth of prostate cancer cells. Hormone therapy can fight prostate cancer by androgen deprivation. It is not yet known if neoadjuvant radiation therapy is a more effective therapy for high-risk prostate cancer. PURPOSE: Two-stage randomized trial to compare the effectiveness and safety of neoadjuvant radiotherapy and hormone therapy followed by radical prostatectomy in men with high-risk locally advanced prostate cancer

To evaluate the efficacy and safety of a pembrolizumab therapy of pembrolizumab in combination with standard salvage radiation therapy (SRT) in patients with biochemical recurrence (BCR) of prostate-specific antigen (PSA) persistence after radical prostatectomy (RP).

This phase II trial tests whether relugolix and radiation therapy works to shrink tumors in patients with prostate cancer that has spread in a limited way to 1 to 5 other parts of the body (oligometastatic). Testosterone can cause the growth of prostate cancer cells. Relugolix lowers the amount of testosterone made by the body. This may help stop the growth of tumor cells that need testosterone to grow. Giving relugolix with radiation therapy may help lower the chance of prostate cancer growing or spreading.

The primary objective of this trial is to determine if adjuvant apalutamide in prostate cancer patients at high risk of developing subsequent metastatic disease results in prolonged biochemically recurrence-free survival after radical prostatectomy (RPE) in comparison to standard of care (SOC).

The overall aim of this project is to test the hypothesis that the addition of ADT to metastasis-directed radiotherapy (MDRT) in well-selected PCa patients with oligo-metastatic disease prolongs the metastases progression-free survival (MPFS) compared to MDRT alone.
