Prostate cancer clinical trials in San Jose

The purpose of this study is to assess the efficacy and safety of opevesostat plus hormone replacement therapy (HRT) compared to alternative abiraterone acetate or enzalutamide in participants with Metastatic Castration-resistant Prostate Cancer (mCRPC) previously treated with one next-generation hormonal agent (NHA). The primary study hypothesis is that opevesostat is superior to alternative abiraterone acetate or enzalutamide with respect to radiographic progression free survival (rPFS) per Prostate Cancer Working Group (PCWG) Modified Response Evaluation Criteria in Solid Tumors (RECIST 1.1), as assessed by Blinded Independent Central Review (BICR), in androgen receptor ligand binding domain (AR LBD) mutation positive and negative participants.

This study is being done to answer the following question: Is the strategy to give higher doses of radiotherapy treatment over a shorter period of time using special equipment and fewer treatments (also known as Stereotactic Body Radiation Therapy or SBRT) as effective as usual external radiation therapy given with a brachytherapy boost (which involves radiation sources inserted directly into the prostate)?

This phase III trial compares stereotactic body radiation therapy (SBRT), (five treatments over two weeks using a higher dose per treatment) to usual radiation therapy (20 to 45 treatments over 4 to 9 weeks) for the treatment of high-risk prostate cancer. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period of time. This trial is evaluating if shorter duration radiation prevents cancer from coming back as well as the usual radiation treatment.

This study will evaluate the efficacy and safety of the combination of inavolisib plus enzalutamide compared with physician's choice of alternative androgen receptor pathway inhibitor (ARPi) or docetaxel in biomarker-selected participants with metastatic castrate-resistant prostate cancer (mCRPC) who have received one prior second-generation ARPi.

This phase III trial compares the effect of adding docetaxel to hormonal therapy and apalutamide versus hormonal therapy and apalutamide alone in treating patients with prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Hormone therapy for prostate cancer, also called androgen deprivation therapy (ADT), uses surgery or drugs to lower the levels of male sex hormones in a man's body. This helps slow the growth of prostate cancer. Apalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. Giving docetaxel in addition to the usual treatment of hormonal therapy and apalutamide may work better in treating patients with metastatic prostate cancer than the usual treatment alone.

This phase III trial studies how well standard systemic therapy with or without definitive treatment (prostate removal surgery or radiation therapy) works in treating participants with prostate cancer that has spread to other places in the body. Addition of prostate removal surgery or radiation therapy to standard systemic therapy for prostate cancer may lower the chance of the cancer growing or spreading.

This clinical trial studies whether an exercise program can be successfully delivered to patients receiving treatment for cancer through virtual sessions and allow patients to exercise in their own home. Treatments for cancer can cause side effects such as fatigue and loss of strength. These side effects can make it difficult to work, take care of family, and do other things the patient wants to do. Preliminary research shows that exercise can help prevent some of these side effects, but it can be more difficult to start an exercise program when a patient is receiving cancer treatment. The exercise program in this study is delivered through telehealth (TH) video calls. The TH sessions are delivered by trained staff that supervise resistance exercises. The trained staff also provide guidance to the patient on completing unsupervised aerobic sessions on their own. This may be a successful way to deliver an exercise program and make it easier for cancer patients to exercise in their own home during treatment.
