A Clinical Trial to Determine the Safety and Efficacy of HB-adMSCs to Provide Protection Against COVID-19

Phase 2

Completed

• Conditions: COVID-19
• Interventions: Biological: HB-adMSCs

• Registration Number: NCT04349631
• Lead Sponsor: Hope Biosciences Stem Cell Research Foundation

Brief Summary

Hope Biosciences is conducting a research study of an investigational product called autologous adipose-derived mesenchymal stem cells (abbreviated as HB-adMSCs) to provide immune support against COVID-19. The study purpose is to evaluate the safety and efficacy of five IV infusions of HB-adMSCs in subjects with no signs of COVID-19.

Detailed Description

This is a Phase II, Open Label, Single-Center, Clinical Trial to Assess Efficacy of HB-adMSCs to Provide Immune Support Against Coronavirus Disease. 51 patients were enrolled. All patients have previously banked their own mesenchymal stem cells at Hope Biosciences. Eligible participants are either 65 years of age or older, have preexisting conditions, or are at high exposure risk of contracting COVID-19. The primary objective of this study is to provide immune support against COVID-19, measured by the presence or absence of adverse events and serious adverse events related to the study drug. In addition, participants will be monitored for overall clinical status by standard clinical laboratories and inflammatory markers. Participants will complete Short Form Health Survey (SF-36) and depression module (PHQ-9) questionnaires.

Exclusion Criteria

Subjects must not have any of the following criteria to be eligible.
