This is a naturalistic treatment and follow-up study of youth with bipolar spectrum disorders (BSDs) across four US sites of The Childhood Bipolar Network (CBN). CBN sites have expertise in diagnosing, assessing, and treating BSDs in youth. The primary aims of this study are to (1) identify and reliably diagnose youth (ages 9 to 19 yrs) with full bipolar disorder (BD) and BSDs, and (2) examine predictors (e.g., mood instability, inflammatory marker C-reactive protein) of clinical outcome over a...

Testing the Safety of the Anti-Cancer Drugs Durvalumab and Olaparib During Radiation Therapy for Locally Advanced Unresectable Pancreatic Cancer
Recruiting
This phase I trial tests the safety and tolerability of olaparib in combination with durvalumab and radiation therapy in patients with pancreatic cancer that has spread to nearby tissue or lymph nodes (locally advanced) and cannot be removed by surgery (unresectable). Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are... Read More

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
