Long-term Safety and Efficacy of Odevixibat in Patients With Alagille Syndrome
Recruiting
The purpose of this study is to assess the long-term safety and effectiveness of odevixibat in participants with Alagille syndrome (ALGS). The participants of this study will have ALGS a rare genetic disorder that can affect multiple organ systems of the body including the liver, heart, skeleton, eyes and kidneys.

Testing Combination Erdafitinib and Enfortumab Vedotin in Metastatic Bladder Cancer After Treatment With Chemotherapy and Immunotherapy
Recruiting
This phase Ib trial evaluates the best dose, potential benefits, and/or side effects of erdafitinib in combination with enfortumab vedotin in treating patients with bladder cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and possesses genetic alterations in FGFR2/3 genes. Erdafitinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal FGFR protein that signals cancer cells to multiply. Th... Read More

Cochlear Implantation in Children With Asymmetric Hearing Loss or Single-Sided Deafness Clinical Trial
Recruiting
This is a two-phase study that compares performance growth pre-implant with current hearing aid (HA) technology versus post-implant with a cochlear implant (CI) in children with either asymmetric hearing loss (AHL) or single-sided deafness (SSD). Post-implant performance with a CI alone is expected to outperform pre-implant performance with a HA. The study also evaluates the effectiveness of bimodal hearing defined as a CI in the poor ear and a HA in the better ear for AHL or a CI in the poor ea... Read More

Functional and Cognitive Rehabilitation of Hoarding Disorder
Recruiting
Hoarding Disorder (HD) is serious and disabling in Veterans. Present in up to 7% of Veterans and even higher symptom rates in older Veterans; HD contributes to functional impairment and poor quality of life. Cognitive Rehabilitation and Exposure/Sorting Therapy (CREST) has shown promising functional improvement and symptom reduction. To reduce burdens and barriers to implementation of CREST, the proposed project will individualize CREST based on cognitive testing and participant preferences, pro... Read More
