Active clinical trials for "Prostatic Neoplasms"

Prostate cancer biochemical recurrence (BCR) occurs in 20-50% of patients following radical prostatectomy or radiotherapy. Due to significant risk of side effects and uncertainty about the benefits, physicians and patients are seeking alternatives to delay androgen deprivation therapy (ADT) for non-metastatic BCR. Long-chain omega-3 fatty acids (LCn3), mainly found in seafood and fatty fish, have beneficial effects against prostate cancer in pre-clinical experimental studies and randomized clinical trials of intermediate prostate cancer outcomes. The current observational evidence also supports testing LCn3 in prostate cancer patients. LCn3 have beneficial effects on inflammation, cardiovascular, psychological, and other outcomes, contrasting sharply with ADT-associated side effects. Investigators propose to conduct a pilot randomized placebo-controlled trial to determine the effects over one year of an innovative LCn3 supplement (5g of omega-3-rich fish oil daily, including 4g of monoglycerides eicosapentaenoic acid (MAG-EPA)) in 40 men experiencing BCR or prostate cancer progression after a curative treatment. This project proposes a simple intervention by dietary supplementation that could eventually help to prevent or delay ADT-related side effects and thus could contribute to diminish the heavy individual and societal burden of prostate cancer. The clinical data generated by this pilot trial will serve as basis for a larger-scale phase II clinical trial.

In prior studies, the investigators synthesized 177Lu-EB-PSMA-617 by conjugating a truncated Evans Blue (EB) molecule and DOTA chelator onto PSMA-617 and labeled it with 177Lu to increase the tumor accumulation and retention for radioligand therapy，and then the investigators evaluated the dosimetry of 177Lu-EB-PSMA-617 and response to single low-dose treatment in patients with metastatic castration-resistant prostate cancer(mCRPC). This study was performed to evaluate the safety and therapy response to 177Lu-EB-PSMA-617 in patients with mCRPC. This is an open-label, randomized study. Different groups with doses of 1.11GBq (30 mCi), 2.00 GBq (54 mCi) and 3.7GBq (100 mCi)of 177Lu-EB -PSMA617 will be injected intravenously. All patients will undergo 68Ga-PSMA PET/CT scans before and after the treatment.

100 mCi of [177Lu]Ludotadipep, the dose determined in the phase 1 clinical trial (FC705-1), was administered repeatedly up to 6 times at intervals of 8 weeks (±2 weeks) to patients with metastatic castration resistant prostate cancer (mCRPC) in order to assess the safety and efficacy.

This trial will evaluate whether the immune-sensitizing effects of immunotherapy (Pembrolizumab) and radiation with or without a PARP-inhibitor (Olaparib) will increase the effects of immunotherapy in men with high-risk localized prostate cancer.

ADT with or without robot-assisted PSMA-radioguided surgery for patients with recurrent prostate cancer.

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.

This clinical trial will evaluate the safety and efficacy of [161Tb]Tb -PSMA-I&T in men with metastatic castration-resistant prostate cancer (mCRPC).

This trial is testing whether a molecularly targeted chemotherapy drug called abemaciclib and an immunotherapy drug called atezolizumab, alone or in combination, are effective in shrinking or preventing the growth of metastatic prostate cancer. The trial is also testing the safety of the combination of abemaciclib with atezolizumab.

A Phase 1/2a, open-label, multicenter study of intramuscular (i.m.) PRL-02 depot in participants with advanced prostate cancer.

NUV-868-01 is a first-in human, open- label, Phase 1/2 dose escalation and expansion study in patients with advanced solid tumors. The Phase 1 and 1b portions include patients with advanced solid tumors and are designed to determine the safety and the dose(s) of NUV-868 to be used as monotherapy and in combination with olaparib or enzalutamide for the Phase 2 portion. In Phase 2, NUV-868 in combination with olaparib or enzalutamide will be given to determine the safety and efficacy of these study treatments. One cohort of patients (with enzalutamide-naïve metastatic castration-resistant prostate cancer) will be randomized to receive either NUV-868 monotherapy, enzalutamide monotherapy, or the combination of NUV-868 + enzalutamide. Patients will self-administer NUV-868 orally daily in 28-day cycles as monotherapy in Phases 1 and 2. In Phases 1b and 2, patients will self-administer NUV-868 orally daily in 28-day cycles in combination with olaparib or enzalutamide daily at standard prescribed doses (Phase 1b) or at the recommended Phase 2 combination dose (RP2cD) that is determined in Phase 1b. Patients will be treated until disease progression, toxicity, withdrawal of consent, or termination of the study.
