Non-healing Venous Leg Ulcers Treated With Standard Care With or Without BR-AC
Recruiting
This study examines a patient population with a non-healing, non-infected venous leg ulcer (VLU) having adequate arterial perfusion with confirmed venous reflux. It is hypothesized that weekly applications of the human placental allograft BioREtainĀ® Amnion Chorion (BR-AC) applied to a non-healing VLU will result in a higher proportion of wounds showing complete healing within 12 weeks of initiating therapy, compared to standard care alone. This study has a crossover period, where subjects on st... Read More

Testing the Addition of the Immunotherapy Drug, Pembrolizumab, to Radiation Therapy Compared to the Usual Chemotherapy Treatment During Radiation Therapy for Bladder Cancer, PARRC Trial
Recruiting
This phase II trial compares the use of pembrolizumab and radiation therapy to chemotherapy with cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C and radiation therapy for the treatment of non-muscle invasive bladder cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C,... Read More
