Filter by:Checkpoint inhibitor therapy represents a significant advance in cancer care. The interaction between PD-1 and PD-L1 induces immune tolerance, and the inhibition of this interaction is an effective treatment strategy for numerous malignancies. Despite its demonstrated potential, immunotherapy is not currently thought to be an effective intervention in the treatment of several immunologically "cold" tumors such as prostate cancer, biliary tract cancers, soft tissue sarcomas, well-differentiated neuroendocrine tumors, microsatellite stable colorectal cancer, pancreatic cancer, and non-triple negative breast cancer. Vascular endothelial growth factor (VEGF) is thought to play a key role in modulating the anti-tumor immune response. Vascular endothelial growth factor (VEGF) is secreted by tumors and leads to endothelial cell proliferation, vascular permeability, and vasodilation. This in turn leads to the development of an abnormal vasculature with excessive permeability and poor blood flow, limiting immune surveillance. In addition, VEGF inhibits dendritic cell differentiation, limiting the presentation of tumor antigens to CD4 and CD8 T cells. Vascular endothelial growth factor (VEGF). VEGF tyrosine kinase inhibitors (TKIs) VEGF-TKIs are currently utilized in the treatment of a variety of malignancies and are widely utilized in combination with checkpoint blockade in the treatment of clear cell kidney cancer. Through the inhibition of VEGF, it may be possible to potentiate the effect of immune checkpoint blockade even in tumors which have traditionally been thought to be unresponsive to immunotherapy. This study aims to evaluate the combination of the immune checkpoint inhibitor atezolizumab and the VEGF-TKI tivozanib in a variety of tumors which have a low response rate to checkpoint inhibitor therapy alone.
The neoadjuvant therapy with apalutamide can significantly improve the prognosis of patients with high-risk and oligometastatic prostate cancer, lower the rate of positive margins, reduce recurrence, and show high safety.
One of the usual approaches to treating intermediate-risk prostate cancer is a type of radiation therapy called SBRT (stereotactic body radiation therapy). SBRT delivers higher than standard doses of radiation over a lower number of treatment sessions. However, there is a 20% chance that intermediate-risk prostate cancer will come back after this treatment. The purpose of this study is to find out whether giving an even higher dose (a "boost" dose) of radiation directly to the main tumor and the standard dose of radiation to the rest of the prostate may cure the cancer or prevent it from coming back for a longer period of time while causing few side effects.
In recent years, quite a few studies have demonstrated the possibility of 177Lu-PSMA-617 therapy as a viable treatment option in metastatic castration resistant prostate cancer (mCRPC), which has been shown desired effect. To increase tumor accumulation and retention for radioligand therapy, and reduce dosage of 177Lu, we conjugated a truncated Evans blue (EB) molecule and DOTA chelator onto PSMA-617 (EB-PSMA) and labeled it with 177Lu. This study is designed to assess the efficiency and response to 177Lu-EB-PSMA (55 mCi) in patients with mCRPC.
PROMISE aims to create a comprehensive nationwide registry of prostate cancer patients with germline pathogenic variants by prospectively screening approximately 5,000 subjects with a confirmed prostate cancer diagnosis, either through tissue biopsy, PSA greater than 100 ng/dL and/or radiographic evidence of disease and receiving systemic therapy for prostate cancer. Patients at all stages of disease will be welcome to participate in the PROMISE Registry. Participants will be recruited & screened over a five-year period. Study participants will be asked to provide a saliva sample to be tested for germline cancer risk variants through Color Health. If the results identify a pathogenic or likely pathogenic variant, an appointment with a genetic counselor from Color Health will be scheduled to discuss the results. Participants will complete a baseline demographic survey that includes self-reported health history, family history of cancer and standardized patient reported outcome (PRO) measures. PROMISE Registry staff will request medical records from the participant's cancer care provider(s) for the purpose of obtaining clinical data. Participants will receive bi-annual newsletters offering information on new developments in treatment and research opportunities, including clinical trials, associated with genetic variants. Eligible participants (those with target germline mutations) will be followed every 6 months to obtain updated health records data and patient-reported outcomes data. Participants will be followed for a minimum of 15 years. The PROMISE registry will help identify prostate cancer patients with pathogenic variants to learn more about how these variants affect patient outcomes. Ultimately, we hope to help patients learn more about their disease and the treatments that they may derive the most benefit from, including the germline genetic biomarker-based clinical trials they may be eligible for.

This single-center study will enroll 40 male participants to complete 2 diffusion magnetic resonance images within 30 days of each other.
The current protocol will examine the use of a plasmid DNA vaccine encoding AR, alone or with T-cell checkpoint blockade, to induce and/or augment therapeutic T-cells following androgen deprivation in patients with newly diagnosed prostate cancer scheduled to undergo prostatectomy. Patients without evidence of metastatic disease, with tissue remaining from a pre-treatment biopsy, and who are being considered for standard treatment by prostatectomy, will be invited to participate and will be on study for up to 15 months.
This is an open-label, randomized, Phase 2b study of ZEN003694 in combination with enzalutamide vs. enzalutamide monotherapy in patients with mCRPC who have progressed on prior abiraterone by PCWG3 criteria. Disease must have progressed on only abiraterone by PCWG3 criteria prior to study entry. The patient population will be separated into two cohorts: Cohort A: Patients with poor response to prior abiraterone defined as: - Abiraterone started in hormone-sensitive prostate cancer (HSPC) disease setting: < 12 months duration on abiraterone or failure to achieve PSA nadir of 0.2 ng/mL while taking abiraterone, or; - Abiraterone started in castrate-resistant prostate cancer (CRPC) disease setting: < 6 months duration on abiraterone or failure to achieve PSA50 response while on abiraterone Cohort B: Patients with response to prior abiraterone, defined as: - Abiraterone started in hormone-sensitive prostate cancer (HSPC) disease setting: ≥ 12 months duration on abiraterone and nadir PSA < 0.2 ng/mL, or; - Abiraterone started in castrate-resistant prostate cancer (CRPC) disease setting: ≥ 6 months duration on abiraterone and confirmed PSA50 response
The study is a randomized study that compares 5 radiation therapy treatments to 2 radiation therapy treatments in men with low or intermediate-risk prostate cancer.
This study aims to investigate the effect of core number and location optimization for targeted prostate biopsy on pathological accuracy.
