Study Details

Study Description

Brief Summary

The study aims to assess the potential benefit and evaluate the safety and tolerability of a single subcutaneous (SC) dose of VIB7734 in hospitalized patients with documented infection of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) with pulmonary involvement. Subjects will be administered a single dose of VIB7734 injected under the skin, assessed for efficacy for 28 days and followed for an additional 42 days.

Condition or Disease	Intervention/Treatment	Phase
Acute Lung Injury	Drug: VIB7734 Drug: Placebo	Phase 1

Detailed Description

This is a randomized, double-blind, placebo-controlled study intended to assess the potential benefit and evaluate the safety and tolerability of a single subcutaneous (SC) dose of VIB7734 in hospitalized patients with documented infection of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) with pulmonary involvement. Efficacy will be assessed during the 28 days following a single administration of VIB7734. Safety will be assessed for 10 weeks following dosing. The pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of VIB7734 in patients with confirmed SARS-CoV-2 infections will also be assessed.

Outcome Measures

Primary Outcome Measures

The proportion of patients who achieve treatment success through Day 28, defined as avoidance of death and critical illness [Day 1 (Baseline) through Day 28]
Critical illness is defined by respiratory failure (requiring any of the following: endotracheal intubation, oxygen delivered by high flow nasal cannula, non-invasive positive pressure ventilation, extracorporeal membrane oxygenation or clinical diagnosis of respiratory failure) or shock (systolic blood pressure < 90 mm Hg, or diastolic blood pressure < 60 mm Hg, or requiring vasopressors)

Secondary Outcome Measures

Number of Participants With Treatment-emergent Adverse Events (TEAEs), Treatment-emergent fatal and life-threatening SAEs, Treatment-emergent Serious Adverse Events [Day 1 (Baseline) through Day 70]
Defined as measure of safety
Change in safety laboratory parameters [Day 1 (Baseline) through Day 70]
Safety evaluation via review of labs (white blood cell (WBC) with differential counts, hemoglobin, platelet count, liver function tests (aspartate aminotransferase [AST], alanine aminotransferase [ALT], and total bilirubin levels), serum chemistry, cardiac troponin coagulation markers (prothrombin time [PT], partial thromboplastin time [PTT], D dimer, fibrinogen), and urinalysis)
