简要总结
This is a Phase 1/2 study evaluating the safety, tolerability and efficacy of IBI314.
详细描述
Phase 1 is a randomized, double-blind, placebo-controlled, single ascending dose study in up to 24 health volunteers. This phase of the study is designed to assess the safety, tolerability and PK of IBI314 administered as a single IV infusion. Phase 2 is a randomized, double-blind, placebo-controlled expansion study in approximately 198 mild to moderate adult patients with COVID-19. This phase of the study is designed to assess the efficacy, safety, PK and PD of IBI314.

入选标准
- •First onset of COVID-19 symptoms <7 days at randomization, symptoms such as fever and/or chills, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, and diarrhea.
- •Have a positive SARS-CoV-2 Reverse Transcription-Polymerase Chain Reaction (RT-PCR) test using an appropriate sample such as nasopharyngeal (NP), nasal, oropharyngeal, or saliva within 72 hours prior to randomization. A historical record of a positive result from a test conducted ≤72 hours prior to randomization is acceptable.
- •Male or female patients ≥18 years of age at the time of signing informed consent.
- •Agree to use an adequate method of contraception throughout the study period and for 6 months after the dose of study drug is administered.
- •Women of childbearing potential (WOCBP) must have a negative urinary pregnancy test at screening.
排除标准
- •Have oxygen saturation (SpO2) ≤93 % on room air at sea level or a ratio of arterial oxygen partial pressure (PaO2 in millimeters of mercury) to fractional inspired oxygen (FiO2) <300, respiratory rate ≥30 per minute, heart rate ≥125 per minute.
- •Have evidence of multi-organ dysfunction/failure. Systolic blood pressure <90 mmHg, diastolic blood pressure <60 mmHg, or requiring vasopressors.
- •Require or anticipated impending need for endotracheal intubation, mechanical ventilation, oxygen delivered by high-flow nasal cannula noninvasive positive pressure ventilation, extracorporeal membrane oxygenation (ECMO).
