The Open, Randomized, Positive Control Clinical Trial of Guluronic Acid (G2013) on SARS-CoV-2 Patients

Recently, the coronavirus disease 2019 (COVID-19) infection, with a vast spectrum of clinical and paraclinical symptoms has been a major health concern worldwide. Therapeutical management of COVID-19 includes antiviral and anti-inflammatory drugs. NSAIDs, as the second-line therapy, are often prescribed to relieve the symptoms of COVID-19. The α-L-guluronic acid (G2013) is a non-steroidal patented (PCT/EP2017/067920) agent with immunomodulatory properties. This study investigated the effect of G2013 on the outcome of COVID-19 in moderate to severe patients.

The disease's symptoms were followed up during hospitalization and for 4 weeks postdischarge in G2013 and control groups. Paraclinical indices were tested at the time of admission and discharge. Statistical analysis was performed on clinical and paraclinical parameters and ICU admission and death rate.

The primary and secondary outcomes indicated the efficiency of G2013 on COVID-19 patients' management. There were significant differences in the duration of improvement of fever, coughing, fatigue/malaise. Also, a comparison of paraclinical indices at the time of admission and discharge showed significant change in prothrombin, D-dimer, and platelet. As the main findings of this study, G2013 significantly decreased the percentage of ICU admission (control:17 patients, G2013:1 patient) and death (control: 7 cases, G2013:0).

These results conclude that G2013 has sufficient potential to be considered for moderate to severe COVID-19 patients, can significantly reduce the clinical and physical complications of this disease, has a positive effect on modulating the coagulopathy process, and aids in saving lives.
