Active clinical trials for "Prostatic Neoplasms, Castration-Resistant"

The purpose of this trial is to evaluate a new drug, HTL0039732, that will be administered on its own (as a monotherapy) and in combination with atezolizumab or with other approved anti-cancer therapies, in participants with advanced solid tumours.

Study CP-MGC018-02 is a study of vobramitamab duocarmazine (MGC018) in combination with lorigerlimab. The study is designed to characterize safety, tolerability, pharmacokinetics (PK), immunogenicity, pharmacodynamics, and preliminary antitumor activity. Participants with relapsed or refractory, unresectable, locally advanced or metastatic solid tumors including, but not limited to, mCRPC, melanoma, pancreatic cancer, hepatocellular carcinoma (HCC), ovarian cancer, and renal cell carcinoma (RCC) will be enrolled. Vobramitamab duocarmazine and lorigerlimab are administered separately on Day 1 of every 4-week (28-day) cycle at the assigned dose for each cohort. Participants who do not meet criteria for study drug discontinuation may receive study drugs for up to 2 years. Tumor assessments are performed every 8 weeks for the initial 6 months on study drugs, then every 12 weeks (± 21 days) until progressive disease (PD). Participants will be followed for safety throughout the study. .

The purpose of this randomized trial is to investigate the efficacy and toxicity of percutaneous high-dose radiotherapy in patients with oligometastases of hormone refractory prostate cancer. The effectiveness will be tested in comparison to an observation group, in which no further therapy is initially given. Treatment can be stereotactically hypofractionated or conventionally fractionated.

The purpose of this study is to assess the safety, efficacy, tolerability, and toxicity of docetaxel alone, in combination with BMS-986218, or in combination with nivolumab plus BMS-986218 in men who have metastatic castration-resistant prostate cancer (mCRPC) that progressed after novel antiandrogen therapy and have not received chemotherapy for mCRPC.

The purpose of this study is to evaluate the effects of 4 cycles of combinatory immunotherapy (ipilimumab and nivolumab), followed by monotherapy nivolumab in participants with immunogenic metastatic castration-resistant prostate cancer.

First-in-human, open-label, sequential dose escalation and expansion study of CPI-0209 in patients with advanced solid tumors and lymphomas. CPI-0209 is a small molecule inhibitor of EZH2.

The purpose of this study is to see if a prostate cancer marker in the blood (mGSTP1) can be used to guide chemotherapy treatment. Based on the level of this blood marker, some men may be able to have breaks in treatment rather than having chemotherapy continuously which is the current standard of care. This study will tell us if having these treatment breaks guided by mGSTP1 can improve how men feel during treatment while still treating the prostate cancer effectively. Docetaxel is a chemotherapy drug that is approved to treat prostate cancer and has been used for many years to treat prostate cancer like yours. Your doctor has already discussed this with you and you have both agreed that docetaxel is the best treatment for you to have at this time. You will have already started this chemotherapeutic treatment with docetaxel.

Study CP-MGC018-03 is a randomized, open-label, Phase 2 study. The study will enroll participants with metastatic castration-resistant prostate cancer (mCRPC) previously treated with one prior androgen receptor axis-targeted therapy (ARAT). ARAT includes abiraterone, enzalutamide, or apalutamide. Participants may have received up to 1 prior taxane-containing regimen, but no other chemotherapy agents. The study will assess efficacy and tolerability of two vobramitamab duocarmazine (MGC018) experimental arms (2.0 mg/kg every 4 weeks [Q4W] and 2.7 mg/kg Q4W) . Approximately 100 participants will be randomized 1:1. Vobramitamab duocarmazine will be administered intravenously (IV) in clinic on Day 1 of each 4-week cycle. Vobramitamab duocarmazine will be administered for up to 26 cycles, approximately 2 years, until criteria for treatment discontinuation are met. Participants will undergo regular testing for signs of disease progression using computed tomography (CT) scans, magnetic resonance imaging (MRI), bone scans, and prostate-specific antigen (PSA) blood tests. Routine examinations and blood tests will be performed and evaluated by the study doctor. An analysis of radiographic progression-free survival (rPFS) will occur after 100 participants have been on-study for at least 6 months.

Hormone tablets, abiraterone (Zytiga®) and enzalutamide (Xtandi®) are approved to treat advanced prostate cancer. However, even if these drugs are helpful, their effectiveness usually diminishes over time. Small pilot studies have indicated that using hormone tablets sparingly, for just long enough to control the cancer, followed by a break in treatment and restarting them later, seems to improve how long hormone tablets can control the cancer. This study aims to find out if this pause/restart strategy is better than taking hormone tablets every day continuously. The study will include 168 people with metastatic castrate resistant prostate cancer in the Netherlands and Australia. Patients will be randomly 1:1 assigned between the control group and the experimental group. In the control group, patients will take the treatment with AA/ENZ every day until the prostate cancer doesn't respond anymore to the treatment. In the experimental group, patients will start with daily AA/ENZ until the PSA has declined for >50%. The treatment will then be paused and monthly PSA measurements will be performed. The treatment will be re-initiated when the PSA has increased to the level of before starting treatment. The treatment will be continued daily until the PSA has again dropped for >50%. This pause/restart cycle will be repeated until the prostate cancer doesn't respond anymore to the treatment.

225Ac-PSMA I&T is a radiopharmaceutical for therapy of prostate cancer. PSMA is overexpressed on prostate cancer cells. Actium-225 is an alpha emitting radionuclide. When PSMA I&T is labelled with Actium-225, it can be applied as therapy for prostate cancer.
