This phase 2 trial tests whether fecal microbiota transplantation (FMT) — transferring gut bacteria from a healthy donor — can help adults with chronic immune thrombocytopenia (ITP) whose disease has not responded to or has relapsed after steroid treatment. Participants will rece…

This study tests whether transplanting a person's own fecal bacteria into the bowel before ileostomy reversal can improve bowel and anal function after rectal cancer surgery. Participants receive four weekly enemas made from their own stool. The goal is to reduce symptoms like le…

This study is testing a drug called deucravacitinib in 10 adults with idiopathic inflammatory myopathies, a group of rare diseases that cause muscle inflammation and weakness. Participants will take one pill daily for 6 months. Researchers will track symptom changes and lab resul…

This study tests a new surgical method for removing non-cancerous or early cancerous growths (submucosal tumors) located where the stomach meets the esophagus. The technique combines two types of scopes (laparoscope and endoscope) with a special step to prepare the blood vessels …

This study compares two surgical methods for treating pelvic organ prolapse, a condition where pelvic organs drop from their normal position. Researchers will randomly assign 86 women to receive either laparoscopic lateral suspension (a keyhole surgery) or transvaginal sacrospino…

This study is looking at whether a blood test that detects tiny traces of tumor DNA (called minimal residual disease, or MRD) can predict if a high-risk gastrointestinal stromal tumor (GIST) will return after surgery. The study will follow 66 patients who have had their tumor rem…

This study will use a special blood test called mass spectrometry to look at immune cells in 500 people with various autoimmune diseases and healthy volunteers. The goal is to find patterns that could help doctors diagnose these conditions sooner. No treatments are being tested; …

This study looks at stored tissue samples from 100 people with advanced osteosarcoma to check for loss of the MTAP protein. Researchers want to see how common this loss is and whether it relates to cancer spread or immune system activity. No new treatment is given; the goal is to…

This study involves 320 adults with advanced rectal cancer who received standard chemoradiotherapy and surgery. Researchers are building a computer model that uses MRI scans and patient data to predict whether the cancer has completely disappeared after treatment. The goal is to …

This study explores whether a simple breathing test done before surgery can help predict when a patient's oxygen levels might drop dangerously low during lung surgery. Researchers will measure how air moves through the lungs while patients breathe normally, then track oxygen leve…

This study looks back at 193 people with stomach, appendix, or colon cancer who had surgery with or without heated chemotherapy (HIPEC). Researchers want to see if HIPEC affects how quickly the bowels start working again after surgery and whether it leads to more complications. T…
