Introduction: Enhancement of mucociliary clearance (MCC) might be a potential target in treating COVID-19. The phytomedicine ELOM-080 is an MCC enhancer that is used to treat inflammatory respiratory diseases.
Patients/methods: This randomised, double-blind exploratory study (EudraCT number 2020-003779-17) evaluated 14 days' add-on therapy with ELOM-080 versus placebo in patients with COVID-19 hospitalised with acute respiratory insufficiency.
Results: The trial was terminated early after enrolment of 47 patients as a result of poor recruitment. Twelve patients discontinued prematurely, leaving 35 in the per-protocol set (PPS). Treatment with ELOM-080 had no significant effect on overall clinical status versus placebo (p = 0.49). However, compared with the placebo group, patients treated with ELOM-080 had less dyspnoea in the second week of hospitalisation (p = 0.0035), required less supplemental oxygen (p = 0.0229), and were more often without dyspnoea when climbing stairs at home (p < 0.0001).
Conclusion: These exploratory data suggest the potential for ELOM-080 to improve respiratory status during and after hospitalisation in patients with COVID-19.
