The Longitudinal Impact of Respiratory Viruses on Bronchiolitis Obliterans Syndrome After Allogeneic Hematopoietic Cell Transplantation (The RV-BOS Study)
NCT05250037
Recruiting
This observational trial studies whether respiratory viruses are the cause of lung disease (bronchiolitis obliterans syndrome \[BOS\] or graft-versus-host disease of the lung) and changes in lung function in patients who have received a donor stem cell transplant. Patients with chronic graft-versus-host disease (cGVHD) are at higher risk of developing BOS. Studies have also shown that patients who had a respiratory viral illness early after their transplant are at higher risk of developing lung... Read More

Randomized Trial Comparing Immediate vs. Deferred Surgery for Symptomatic ERM
NCT05145491
Recruiting
Vitrectomy to remove an epiretinal membrane (ERM) is one of the most common procedures performed by retinal surgeons. Patients who present with significant macular changes on optical coherence tomography (OCT) but relatively good vision are often advised to defer surgery until vision declines to 20/40 or worse. However, it is unknown if delaying surgery, which allows the foveal architecture to remain compromised and potentially to deteriorate, results in worse visual acuity outcomes than if surg...

NCT05058651
Recruiting
This phase II/III trial compares the effect of immunotherapy with atezolizumab in combination with standard chemotherapy with a platinum drug (cisplatin or carboplatin) and etoposide versus standard therapy alone for the treatment of poorly differentiated extrapulmonary (originated outside the lung) neuroendocrine cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that has spread from where it first started (primary s...

APOLLO: A Randomized Phase II Double-Blind Study of Olaparib Versus Placebo Following Curative Intent Therapy in Patients With Resected Pancreatic Cancer and a Pathogenic BRCA1, BRCA2 or PALB2 Mutation
NCT04858334
Recruiting
This phase II trial investigates how well the addition of olaparib following completion of surgery and chemotherapy works in treating patients with pancreatic cancer that has been surgically removed (resected) and has a pathogenic mutation in BRCA1, BRCA2, or PALB2. Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a t... Read More
