Zanamivir for dengue that causes warning signs
This Phase 2 study tests whether zanamivir given through a vein can improve outcomes in people with dengue infection who have warning signs. It may help by reducing the body problems dengue can cause in blood vessels and fluid balance.
Barranquilla, AtlánticoAges 7 years+ - NCT05645107RecruitingPhase 3
XEMBIFY plus usual care to prevent infections
This Phase 3 study tests whether XEMBIFY (an immune protein therapy) plus standard medical treatment can better prevent serious or repeated infections. It is for people with certain cancers of blood/immune systems who are already having trouble with infections.

Liver Function and Safety Study of AHB-137 Injection
This study tests how a new investigational drug called AHB-137 moves through your body and affects safety in people with mild-to-moderate liver problems compared to people with normal liver function. The goal is to understand if the drug works safely in people whose livers don't work as well as they should.
