electroCore, Inc. announced that the original author manuscript from the SAVIOR-1 study; a prospective, randomized, controlled study evaluating non-invasive vagus nerve stimulation (nVNS) using gammaCore Sapphire in patients admitted to the hospital for treatment of COVID-19; is available on MedRxiv and has been submitted for peer review. This study was an investigator-initiated trial conducted at the Hospital Clínico Universitario de Valencia, Spain. The SAVIOR-1 study enrolled 110 patients over 18 years of age between April 2020 and February 2021. A total of 97 patients comprised of 47 treatment subjects and 50 control subjects provided baseline demographic and medical history data. The study was designed to evaluate the safety and feasibility of nVNS when administered in addition to the then-standard of care in patients hospitalized with active SARS-CoV-2 infection compared with standard of care alone. The analyses identified significant treatment differences for certain biomarkers of inflammation. Decreases from baseline in C-reaction protein (CRP) levels were significantly greater for the nVNS treatment group as compared to the control group throughout the five-day period combined (p= 0.010) and on day 5 compared to the day 1 baseline period alone (p= 0.012). At day 1, CRP levels were highly elevated for 90% of all subjects, but by days 3 and 5, the percentage of subjects with normal CRP levels improved markedly in the nVNS group with day 3 CRP levels at 17.9% vs. 52.2% in the control (p=0.010). Additionally, the nVNS group had a significantly greater decrease from baseline in procalcitonin level at day 5 (p=0.004) as compared to the control group. Increased levels of CRP, procalcitonin and d-dimer have all been reported to be associated with more severe disease and the lower levels of these markers in the nVNS treated group may represent the initial impact of nVNS therapy to potentially improve the course of a patients COVID-19 symptoms.
