Guangzhou, GuangdongAges 18 years+ - NCT03609398RecruitingPhase 2
Phase 2 study of a Rift Valley fever vaccine for safety
This study tests how safe a Rift Valley fever (RVF) vaccine is and how strongly it triggers the body’s immune response. You may be eligible if you are at risk of RVF exposure and your blood test shows you don’t already have strong protection.
Fort Deterick, MarylandAges 18–65 - NCT03625011RecruitingPhase 4
Gabapentin before tonsil surgery to reduce pain
This trial tests whether giving gabapentin before pediatric tonsil (and possibly adenoid) removal can reduce postoperative pain. It may help children feel more comfortable after surgery while still being safe to use in the right patients.
Atlanta, GeorgiaAges 3–18 - NCT03625739Recruiting
Study how TB medicines move through children’s bodies
This study looks at how common TB medicines are absorbed, used, and cleared in children who are already taking treatment for tuberculosis. It may help doctors choose safer and more effective doses for children.
BeijingAges 1 day–18 years - NCT03643718Recruiting
Emergency surgery and trauma patient registry online
This trial is a web-based registry that collects information about people who need emergency surgical or non-surgical treatment for sudden (acute) problems. Your information can help doctors better understand and improve emergency care and decision-making.

Testing a CD19 CAR T cell treatment for relapsed blood cancers
This Phase 1 study tests the safety and best dose of a CD19 CAR T cell therapy (azer-cel) in people whose B-cell blood cancer has returned or did not respond to treatment. It may help people with relapsed/refractory B-ALL or certain aggressive or large B-cell lymphomas, including after or before prior CAR T treatment.
Gilbert, ArizonaAges 18 years+ - NCT03665675RecruitingEarly Phase 1
Immune cell treatment to control CMV or adenovirus after transplant
This early-phase study tests donor immune cells made to recognize CMV (a virus) or adenovirus, given to help control virus reactivation after a solid organ or bone marrow transplant. It may help reduce ongoing or worsening viral infection when standard antiviral medicines are hard to tolerate or not working well.
Columbus, OhioAges 1–85 - NCT03671967RecruitingPhase 4
Compare two antibiotics for hard-to-treat E. coli and Klebsiella bloodstream infections
This trial tests whether piperacillin-tazobactam works as well as meropenem to treat bloodstream infections caused by certain E. coli or Klebsiella germs that resist common cephalosporin antibiotics. It may help you avoid a “bigger” antibiotic if the study drug is equally effective.
Calgary, AlbertaAges 18 years+ - NCT03684655RecruitingPhase 2
PET-MR scan study of immune activity in people with HIV
