A Safety, Tolerability, and Efficacy Study of IBI314 in Patients With Mild to Moderate COVID-19

This is a Phase 1/2 study evaluating the safety, tolerability and efficacy of IBI314.

Study Overview

• Status: Terminated
• Conditions: COVID-19
• Intervention / Treatment: Biological: IBI314(low dose); Biological: IBI314(high dose); Biological: IBI314(medium dose); Other: Placebo

Detailed Description

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.

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.

Women of childbearing potential (WOCBP) must have a negative urinary pregnancy test at screening.

Main Exclusion Criteria:

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).
