Fecal Microbiota Transplantation for Chronic Granulomatous Disease-Associated Colitis
Recruiting
Background:
Chronic granulomatous disease (CGD) weakens the body's defense against germs. CGD can also damage the colon. It can cause inflammation (colitis) that disrupts the good bacteria. Placing good bacteria from donor stool into the intestine of a person with CGD (called fecal microbiota transplantation, or FMT) may help.
Objective:
To see if FMT can reduce inflammation in the colon.

Testing of Tazemetostat in Combination With Topotecan and Pembrolizumab in Patients With Recurrent Small Cell Lung Cancer
Recruiting
This phase I trial tests the safety, side effects, and best dose of tazemetostat in combination with topotecan and pembrolizumab in treating patients with small cell lung cancer that has come back after a period of improvement (recurrent). Tazemetostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as topotecan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing... Read More

Sleep Disordered Breathing With Opioid Use
Recruiting
There is an increased risk for sleep disordered breathing (SDB), sleep-related hypoventilation and irregular breathing in individuals on chronic prescription opioid medications. Almost 30% of a veteran sleep clinic population had opioid-associated central sleep apnea (CSA). The proposal aims to identity whether oxygen and acetazolamide can be effective in reducing unstable breathing and eliminating sleep apnea in chronic opioid use via different mechanisms. We will study additional clinical para... Read More
