ABSTRACT
Post-COVID syndrome develops after COVID-19 (COronaVIrus Disease 2019) and leads to cumulative effects in the form of shortness of breath and impaired lung function. Notably, patients with airway inflammation and COVID-19 were found to have increased concentrations of hyaluronic acid (HA). Since bovhyaluronidase azoximer (Longidase®) catalyzes the hydrolysis of HA, this drug has the potential to reduce HA levels and improve lung function in patients with post-COVID syndrome. The aim of the DISSOLVE trial, which was conducted early in the pandemic, was to investigate the efficacy and safety of bovhyaluronidase azoximer in patients with symptoms associated with post-COVID syndrome. Methods. An open, prospective, controlled, comparative, multicenter clinical trial (NCT04645368) included adult patients (n = 160) who had post-COVID syndrome. Patients in the treatment group (n = 81) received bovhyaluronidase azoximer, and individuals in the control group (n = 79) were followed up without intervention. The study included physical examination, evaluation of forced vital capacity (FVC), assessment of dyspnea with the Modified Medical Research Council Dyspnea Scale (mMRC), 6-minute walking test, and pulse oximetry. These indicators were measured on 3 visits, at days 1 (baseline), 75, and 180. In addition, the number of patients who experienced adverse events and serious adverse events were recorded. Results. Baseline patient characteristics in the treatment group and the control group were similar. In the treatment group, there was a statistically significant reduction in residual pulmonary abnormalities after visit 2 (day 75) and visit 3 (day 180). In addition, FVC, pulse oximetry values, and functional exercise tolerance increased statistically significantly at days 75 and 180 compared to baseline. The mMRC scores for dyspnea decreased statistically significantly in the treatment group over 75 days. The safety profile of the drug was reported to be favorable throughout the study. Conclusion. Treatment with bovhyaluronidase azoximer in patients with post-COVID syndrome showed improvement in FVC, pulse oximetry, functional exercise tolerance, and mMRC dyspnea. © Chuchalin A.G. et al., 2023.
