- NCT07378306RecruitingPhase 2
Fasting-mimicking diet with chemo-immunotherapy for triple-negative breast cancer
This trial tests whether adding a special low-calorie diet (called a fasting-mimicking diet) to standard chemotherapy and immunotherapy can help treat triple-negative breast cancer before surgery. It aims to see if this combination makes the treatment work better.

Safety study of FHND1002 granules in healthy adults
This trial tests a new medication called FHND1002 in healthy adults aged 18 to 45. The goal is to check its safety, how well the body tolerates it, and how it is processed. It is one of the first tests in humans.
Lanzhou, GansuAges 18–45 - NCT06762743Enrolling by invitationPhase 1
Comparing two brivaracetam oral solutions in healthy adults
This study tests whether two different forms of an oral solution of brivaracetam (a seizure medication) have the same effect in the body. Healthy adults take one dose and have blood samples collected—first on an empty stomach, and later after a high-fat meal—to compare how the drug is absorbed.
