Testing blood and swab markers to track new cystic fibrosis treatments
This study looks for simple signals (markers) that may show whether cystic fibrosis treatments are working. It includes people who take CF “modulator” medicines like ivacaftor, people who don’t, and people whose cystic fibrosis was ruled out after testing.
ParisAges Any age - NCT05170971Recruiting
Fecal transplant trial for worsening liver failure
This trial studies fecal microbiota transplantation (a transfer of healthy gut bacteria from a donor) to help people with worsening liver failure. It may help by changing gut bacteria, which can affect complications like confusion, fluid buildup, infections, and kidney problems.
Ningbo, ZhejiangAges 18–65 - NCT05975749RecruitingPhase 2
Trastuzumab, serplulimab, and chemo after stomach cancer surgery
This Phase 2 study looks at whether adding serplulimab to trastuzumab and chemotherapy after surgery can lower the chance of stomach cancer coming back. It is for people with HER2-positive stage II–III stomach adenocarcinoma who have already had curative surgery with lymph node removal.
Shanghai, Shanghai MunicipalityAges 20–80 - NCT06187597RecruitingPhase 2
Toripalimab after chemoradiation for older esophageal cancer
This study tests whether adding a drug called toripalimab after standard chemoradiation can help older adults with esophageal cancer. The goal is to see if this treatment can keep the cancer from coming back after initial therapy.
