This phase II trial studies the effect of adding pembrolizumab to gemcitabine in treating patients with non-muscle invasive bladder cancer whose cancer does not respond to Bacillus Calmette-Guerin (BCG) treatment. Chemotherapy drugs, such as gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the patient's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Adding pembrolizumab to gemcitabine may delay the return of BCG-unresponsive bladder cancer for longer period compared to gemcitabine alone.

This is an unblinded, randomized clinical study comparing the efficacy of DNA damaging chemotherapy using carboplatin, to standard of care therapy for patients who have metastatic castrate resistant prostate cancer. This trial will use olaparib or carboplatin as initial therapy with crossover to the alternate or second-line drug after first progression for patients with tumors containing BARD1, BRCA1, BRCA2, BRIP1, CHEK1, FANCL, PALB2, RAD51B, RAD51C, RAD51D, or RAD54L inactivating mutations. Participants are randomized (1:1) and receive either carboplatin (AUC 5, IV) every 21 days, first or olaparib taken orally (300 mg), twice daily in 28 day cycles, until intolerance, complete response, or progression by Prostate Cancer Working Group 3 (PCWG3) criteria. Participants then crossover from the first-line therapy to the second-line therapy with the opposite study medication and receive treatment to intolerance or progression (whichever is first). Enrolled participants will be allowed to crossover to second line therapy if they continue to meet initial eligibility criteria, and at least three weeks have elapsed since last administration of either carboplatin or olaparib. Throughout the study, safety and tolerability will be assessed. Progression will be evaluated with bone scan, CT of the abdomen/pelvis, or MRI and PSA as per PCWG3 criteria.

This phase II trial studies the effect of pembrolizumab alone compared to the usual approach (chemotherapy [cisplatin and carboplatin] plus radiation therapy) after surgery in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or patients with a second head and neck cancer that is not from metastasis (primary). Radiation therapy uses high energy radiation or protons to kill tumor cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Carboplatin is also in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. 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. Giving pembrolizumab alone after surgery may work better than the usual approach in shrinking recurrent or primary head and neck squamous cell carcinoma.

The purpose of this study is to evaluate the safety, tolerability, and efficacy of AntiBKV in reducing BKV DNAemia and progression to biopsy-confirmed BKVAN in kidney transplant recipients. This study has an operationally seamless phase II/III design. The phase II part will evaluate the safety of AntiBKV in kidney transplant recipients and establish antiviral proof of concept. The phase II part includes a dose-comparison part to generate additional PK and PD data of AntiBKV. The phase III part will assess the efficacy of AntiBKV in kidney transplant recipients. For both the phase II and phase III parts, participants will be randomized to receive either four doses of AntiBKV or four doses of placebo (every four weeks). In phase II, 60 participants will be first randomized (1:1) to receive either four doses of 1,000 mg of AntiBKV or placebo. In an additional dose-comparison extension, another 30 participants will be enrolled and randomized (1:1:1) to receive either four doses of 1,000 mg AntiBKV, four doses of 500 mg AntiBKV, or placebo. Based on a Day 141 analysis after phase II the sample size for the phase III part of the trial will be defined. Both the phase II and phase III parts will follow identical study assessments and schedules for participants. Eligible participants will receive an intravenous infusion of the investigational medicinal product (IMP) that will be administered four times at a four-week interval. For the first ten participants enrolled in the study, the infusion time will be at least 60 minutes. Provided there are no safety concerns observed with the first ten participants the duration of subsequent infusions will be at least 30 minutes. After administration of the final dose, participants will return as out participants for periodic safety, BKV DNAemia, and PK follow-up assessments until the end of the trial visits, 26 weeks post last IMP application. Regular kidney biopsies will be performed at baseline (prior to infusion) and on Day 141 (8 weeks after full dosing). An additional biopsy will be taken on Day 267 (optional) and if clinically indicated.

This phase III trial compares the effect of stereotactic radiosurgery to standard of care memantine and whole brain radiation therapy that avoids the hippocampus (the memory zone of the brain) for the treatment of small cell lung cancer that has spread to the brain. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. Whole brain radiation therapy delivers a low dose of radiation to the entire brain including the normal brain tissue. Hippocampal avoidance during whole-brain radiation therapy (HA-WBRT) decreases the amount of radiation that is delivered to the hippocampus which is a brain structure that is important for memory. The drug, memantine, is also often given with whole brain radiotherapy because it may decrease the risk of side effects related to thinking and memory. Stereotactic radiosurgery may decrease side effects related to memory and thinking compared to standard of care HA-WBRT plus memantine.

This is a proposal to develop a Balanced Reach Training Protocol (BRTP) to evaluate and train dynamic standing balance. The BRTP is based upon the Balanced Reach Test (BRT) that the investigators previously developed and validated. In the BRT subjects stand and point to a target disk moving unpredictably across a large projection screen in front of them without stepping. Body movements undertaken to track the disk are integral to many daily activities and represent an important class of "expected" balance disturbances that can precipitate falls. The BRTP employs engineering and psychophysical methods, and exploits advances in real time computing in a novel and innovative way to more effectively evaluate and train balance function. The BRTP presents a challenging reaching/tracking task that subjects perform at their limit of balance. The BRTP is an objective, quantitative test that can evaluate balance function without floor or ceiling effects, and train balance across the spectrum of aging, disease, and injury.
