Have evidence of multi-organ dysfunction/failure. 4. Systolic blood pressure <90 mmHg, diastolic blood pressure <60 mmHg, or requiring vasopressors. 5.

Detailed Description

Phase 1 is a randomized, double-blind, placebo-controlled, single ascending dose study in up to 48 ambulatory adult patients with COVID-19. This phase of the study is designed to assess the safety, tolerability, PK, and PD of IBI314 administered as a single IV infusion. Phase 2 is a randomized, double-blind, placebo-controlled expansion study in approximately 192 ambulatory adult patients with COVID-19. This phase of the study is designed to assess the efficacy and safety of IBI314, administered by single IV infusion at dose levels that meet none of the termination criteria for dose escalation in Phase 1 of the study.


Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
