Complement-mediated Hemolytic Diseases
Conditions
Brief summary
NTQ5082 capsule is a small molecule CFB factor inhibitor. The study is a randomized, open label, two sequence, two period, double crossover-design phase 1 clinical trial to evaluate the food effect on PK after a single oral administration of NTQ5082 capsules and the safety and tolerability of single oral administration of NTQ5082 capsules on an empty stomach (i.e, fasting) as well as after a meal (i.e. fed) in healthy subjects
