Docetaxel Versus Cabazitaxel Post Abiraterone or Enzalutamide

Metastatic Prostate Cancer

Prostate cancer (PCa) is the most frequently diagnosed cancer in Canadian men. While the majority of PCa is slow growing and responds well to first line treatment, a proportion of cases (10%) progress to metastatic form resulting in more than 4 000 deaths annually in Canada and 250 000 worldwide. Currently, first line treatment for PCa includes surgery, radiation and androgen deprivation therapy (ADT). A rapid evolution in the understanding of disease biology, combined with approvals of new therapies including immunotherapy, novel chemotherapy, hormonal agents and a bone calcium matrix-targeted radionuclide, along with further drugs in development, have made treatment decisions for metastatic castration-resistant prostate cancer (mCRPC) increasingly complex and challenging. This is a Phase II Study of Cabazitaxel plus prednisone in patients with metastatic castration-resistant prostate cancer (mCRPC). The current study is designed to determine if cabazitaxel will improve progression free survival (PFS) or overall survival (OS). This study will enroll patients with mCRPC, who have been previously treated and progressed under docetaxel or abiraterone regimen. Patients must meet the study eligibility criteria and must be competent to give informed consent.

CASCARA: Castration Sensitive Carboplatin, Cabazitaxel and Abiraterone

Prostate Cancer

This is a phase II clinical trial in patients with metastatic castration sensitive prostate cancer. The objective of the study is to determine the efficacy and further define the safety of the treatment combination. This study will evaluate dose levels of carboplatin AUC 4 with cabazitaxel 20 mg/m2. Patients will be treated with the combination of ADT and carboplatin and cabazitaxel for 6 cycles. After 6 cycles of chemotherapy, they will start abiraterone with ADT. The primary objective is to determine the percent of subjects that have no PSA or radiographic progression at 1 year. Secondary objectives will include determining the progression-free survival, time to PSA nadir and time to PSA progression of carboplatin and cabazitaxel in combination with ADT.

Conventional or Hypofractionated Radiation Therapy in Treating Patients With Prostate Cancer

Stage I Prostate Cancer AJCC v8Stage II Prostate Cancer AJCC v82 more

This phase III trial studies how well hypofractionated radiation therapy works compared to the conventional one in treating patients with prostate cancer. Radiation therapy uses high energy beams to kill tumor cells and shrink tumors. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects.

Phase II Study of Pencil Beam Scanning Proton Stereotactic Body Radiation Therapy for Prostate Cancer...

Prostate Cancer

This is a single arm phase II study of image-guided pencil beam scanning proton SBRT (40Gy RBE in 5 fractions delivered every other day) for patients with low- and intermediate-risk prostate cancer. The primary aim is to assess GU/GI toxicity of proton SBRT and compare this to historic outcomes associated with photon-based prostate SBRT. The primary endpoint is 2-year grade 3+ GU/GI toxicity free rate by CTCAE v5.0, which is expected to be ≥95%. Toxicity will be evaluated by the treating radiation oncologist at least once during SBRT, then following SBRT at 1, 3, 6, 12, 18, and 24 months. The treatment will be considered safe if grade 3 or higher GU/GI toxicity free rate at 2 years is >85% (95% rate expected with a 10% non-inferiority margin). The accrual goal is 61 patients over 3 years. To ensure that unexpected significant toxicity is identified, all grade 3 or higher toxicities will be reported to the study PI and the trial will stop accruing if at any point 4 or more patients experience a grade 3 or higher toxicity after completing SBRT. This is felt to be conservative given the vast experience with photon SBRT at this dose with an expected G3+ toxicity of ~5%. Secondary objectives are to examine patient-reported urinary, gastrointestinal, sexual, and financial outcomes using IPSS, EPIC-26, and COST questionnaires at the same follow-up timepoints as above. Baseline measures of these domains will be obtained prior to treatment as well. Clinical outcomes will also be evaluated with PSA measured at each follow-up, as well as prostate MRI and biopsies at 2 years. Patients will be followed for at least 2 years to determine rates of PSA relapse, salvage treatment, development of metastases, death from prostate cancer, and overall survival. A dosimetric comparison will be performed where each patient will be planned for proton and photon SBRT to determine possible advantages of proton SBRT.

Pembrolizumab and Lenvatinib in Advanced/Metastatic Neuroendocrine Prostate Cancer

Prostate Cancer MetastaticNeuroendocrine Tumors

Eligible patients will be treated with the combination of lenvatinib and pembrolizumab. A cycle equals 21 days and therapy will continue until radiographic progression, intolerable toxicity, or patient/physician wishes to discontinue protocol therapy. A maximum of 35 cycles may be administered. On Day 1, when both pembrolizumab and lenvatinib are administered, patients should take the lenvatinib per their normal routine.

A Study of AMG 340 in Subjects With Metastatic Castrate-Resistant Prostate Carcinoma

Metastatic Castration-resistant Prostate Cancer

This is a phase 1, open-label study evaluating the safety, clinical pharmacology and clinical activity of AMG 340, a PSMA x CD3 T-cell engaging bispecific antibody, in subjects with metastatic castrate-resistant prostate cancer (mCRPC) who have received 2 or more prior lines of therapy. The study consists of 2 parts, a monotherapy dose escalation (Arm A) and a monotherapy dose expansion (Arm B). Once the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) is identified in Arm A, Arm B will be initiated to further characterize the safety, tolerability and pharmacokinetic (PK) profile of the MTD/RP2D dose of AMG 340 monotherapy in subjects with mCRPC.

Radium-223 in Biochemically Recurrent Prostate Cancer

Biochemical Recurrent Prostate Cancer

Background: Some men who have been treated for localized prostate cancer with surgery or radiation still show signs of the disease in their blood. This is called biochemically recurrent prostate cancer. Radium-223 is a small molecule. It uses radiation to kill cancer cells and improves survival in advanced prostate cancer. Researchers want to see if it can treat prostate cancer and induced immune changes earlier in the disease when the cancer is only detectable by prostate specific antigen (PSA) in the blood. Objective: To learn how Radium-223 affects men with rising PSA but no evidence of cancer on conventional CT or bone scan, but positive findings on PET or molecular imaging in the bones. The primary focus is impact on the immune system with secondary focus on impact on PSA and imaging. Eligibility: Men ages 18 and older with prostate cancer who have had surgery and/or radiation, but their PSA is rising even though no disease is visible on routine imaging scans (CT or bone scans). Patients are required to have PET or molecular imaging findings in bones, but not organs (lymph nodes are allowed). Design: Participants will be screened with a medical history and physical exam. Their ability to do normal tasks will be reviewed. They will give tissue samples or a report from their doctor about their cancer. They will have blood and urine tests. They will have an electrocardiogram to measure heart function. They will have a scan of their chest and abdomen using radiation or magnetic resonance imaging. They will have a bone scan with injection of Tc99. They will have a positron emission tomography scan with intravenous (IV) injection of 18F-NaF. Participants will get Radium-223 by IV. For this, a small plastic tube is put into an arm vein. Radium-223 will be given on Day 1 of each cycle (1 cycle = 4 weeks) for up to 6 cycles. Participants will repeat the screening tests during the study. They will also complete Quality of Life Surveys and give stool samples. After treatment, participants will have long-term follow-up every 6 weeks for the rest of their lives....
