Effectiveness and Safety of New Oral Antivirals for COVID-19 — ESOA-19  

COVID-19 Clinical Trial

Official title: Post-marketing Surveillance Study of the Effectiveness and Safety of New Oral Antivirals for Outpatients With Mild-moderate COVID-19

Status Active, not recruiting

Clinical Trial Summary

There is an increased lack of short- and long-term real-life effectiveness and safety data on new oral antivirals authorised and commercialised to treat COVID-19. To date, only two clinical trials have been published with data on the efficacy and safety of the use of the Paxlovid® and Lagevrio®. Since there is a public health, political, social and economic pressure to prevent severity, hospitalisation and death from COVID-19, monitoring the effectiveness and safety of commercialised oral antiviral therapies against COVID-19 has become emergent pharmacovigilance and public health task. The objective of the study is to monitor the post-marketing safety and effectiveness of the new oral antivirals indicated for the treatment of COVID-19, namely Nirmatrelvir/Ritonavir (Paxlovid®) and Molnupiravir (Lagevrio®), having as holders of the Authorization of Market introduction to Pfizer Europe MA EEIG and Merck Sharp & Dohme B.V., respectively.

Clinical Trial Description

There is an increased lack of short- and long-term real-life effectiveness and safety data on new oral antivirals authorised and commercialised to treat COVID-19. To date, only two clinical trials have been published with data on the efficacy and safety of the use of the Paxlovid® and Lagevrio®. Since there is a public health, political, social and economic pressure to prevent severity, hospitalisation and death from COVID-19, monitoring the effectiveness and safety of commercialised oral antiviral therapies against COVID-19 has become emergent pharmacovigilance and public health task6. A real-life cohort event monitoring system allows for the monitoring of newly introduced oral antivirals, in addition to existing spontaneous reporting systems and healthcare database studies (i.e., secondary data), as it is complementary to these systems in several ways. First, it is better suited to capture the more frequent AE, including those that are not medically attended. It generates more comprehensive safety data, e.g. on disease course and the impact of the AE. Moreover, there is insufficient data on these new medicines in real clinical practice, particularly from large-scale studies on the long-term efficacy or safety. This work, with scientific and academic interest but, essentially, clinical and regulatory importance, constitutes a duty of the regional pharmacovigilance units. As such, it is also an obligation of the Pharmacy and Therapeutics Commissions, based on the legislation in force, to "collaborate in studies to monitor the safety and effectiveness of medicines promoted in the context of the National Pharmacovigilance System". ;
