Phase 1
Withdrawn
Conditions
Covid-19
Interventions
Biological: COVI-GUARD
Drug: Placebo
Other: Standard of Care
Registration Number
NCT04454398
Lead Sponsor
Sorrento Therapeutics, Inc.
Brief Summary

Randomized, placebo-controlled study to evaluate the safety, pharmacokinetics and efficacy of a single dose of STI-1499 (COVI-GUARD™) in hospitalized patients with moderate COVID-19

Detailed Description

This study is a randomized, double-blind, placebo-controlled study to evaluate the safety, pharmacokinetics and efficacy of a single dose of STI-1499 (COVI-GUARD™), a COVID-19 targeting monoclonal antibody, in hospitalized patients with moderate COVID-19. Four dose levels will be tested: 10 mg, 30 mg, 100 mg, and 200 mg.

Target Recruitment
Not specified
Inclusion Criteria
  • Evidence of moderate COVID-19, diagnosed standard RT-PCR assay or equivalent testing
  • Willing and able to comply with study procedures and follow-up visits
  • Subject or family member/caregiver must have provided written informed consent which includes signing the institutional review board approved consent form prior to participating in any study related activity. However, if obtaining written informed consent is not possible, other procedures as provided in the March 27th, 2020 FDA Guidance on Conduct of Clinical Trials of Medical Products during COVID-19 Pandemic, Question 10, may be used.
Exclusion Criteria
  • Clinical signs indicative of severe COVID-19
  • Rapidly progressive COVID-19 which is likely to progress to "severe" within 24 hours
  • Documented infection other than COVID-19
  • Any medical condition that, in the Investigator's opinion, could adversely impact safety
  • Pregnant or lactating women
  • Has participated, or is participating, in a clinical research study evaluating COVID-19 convalescent plasma, monoclonal antibodies (mAbs) against SARS-CoV-2, or intravenous immunoglobulin (IVIG) within 3 months or less than 5 half-lives of the investigational product (whichever is longer) prior to the screening visit. Note: Participants who have been prescribed hydroxychloroquine or chloroquine with or without azithromycin or other approved products for the off-label treatment of COVID-19 prior to study enrollment may be included and may continue to receive these agents so long as the dose remains stable. Additionally, any approved or authorized treatment (e.g., remdesivir, dexamethasone or treatments approved under an Emergency Use Authorization) is allowed.
