Bicalutamide Therapy in Young Women With NAFLD and PCOS
NCT05979389
Recruiting
Nonalcoholic steatohepatitis (NASH), or fat-related liver inflammation and scarring is projected to be the leading cause of cirrhosis in the United States (U.S.) within the next few years. Women are at disproportionate risk for NASH, with approximately 15 million U.S. women affected. There is an urgent need to understand risk factors for NASH and its progression in women, and sex hormones may provide a missing link. This study will study the contribution of androgens to liver injury and progress... Read More

Study to Evaluate the Efficacy, Safety, and Tolerability of Efzofitimod in Patients With Systemic Sclerosis (SSc)-Related Interstitial Lung Disease (ILD) (SSc-ILD)
NCT05892614
Recruiting
This is a 2-Part study with Part A, a double-blind, randomized, placebo-controlled, PoC study to evaluate the efficacy, safety, and tolerability of efzofitimod in patients with SSc-ILD. The primary objective of the study is to evaluate the PoC for efficacy in a population with SSc-ILD. While improvement of ILD is the outcome of interest, the study will also evaluate changes in the skin. After initial screening (up to 4 weeks), approximately 25 eligible participants will be randomized 2:2:1 to 1... Read More

A Trial Comparing Unrelated Donor BMT With IST for Pediatric and Young Adult Patients With Severe Aplastic Anemia (TransIT, BMT CTN 2202)
NCT05600426
Recruiting
Severe Aplastic Anemia (SAA) is a rare condition in which the body stops producing enough new blood cells. SAA can be cured with immune suppressive therapy or a bone marrow transplant. Regular treatment for patients with aplastic anemia who have a matched sibling (brother or sister), or family donor is a bone marrow transplant. Patients without a matched family donor normally are treated with immune suppressive therapy (IST). Match unrelated donor (URD) bone marrow transplant (BMT) is used as a... Read More

Study of Bevacizumab in Combination With Chemoimmunotherapy and Atezolizumab in Patients With Extensive Stage Small Cell Lung Cancer and Liver Metastases
NCT05588388
Recruiting
This clinical trial aims to assess whether the addition of bevacizumab to atezolizumab and chemotherapy can improve response to treatment and progression-free survival in patients with extensive-stage small cell lung cancer (ES-SCLC) with liver metastases. The main questions it aims to answer are: * In patients with ES-SCLC with liver metastases, can bevacizumab in combination with atezolizumab and chemotherapy prolong the length of time that the cancer does not progress? * Is bevacizumab safe...

Oxytocin Pharmacokinetics and Pharmacodynamics
NCT05488457
Recruiting
Oxytocin is the first-line drug to promote contraction of the uterus and prevent atony immediately after delivery. Nonetheless, unpredictable uterine atony refractory to oxytocin affects roughly 250,000 parturients annually in the U.S. and rates are increasing. This two-part study will measure the action of oxytocin at cesarean delivery. The first part will measure the pharmacokinetics of a single intravenous (IV) dose of deuterium-labeled oxytocin. The second part will measure the pharmacodynam... Read More
