Merck to seek emergency authorization for oral Covid treatment after ‘compelling results’ in trials
KEY POINTS A phase 3 trial of Merck and Ridgeback Biotherapeutics’ oral antiviral treatment molnupiravir showed it reduced the risk of hospitalization or death by around 50% in Covid-19 patients. Merck plans to seek Emergency Use Authorization in the U.S. and submit marketing applications to other global drug regulators. If authorized by regulatory bodies, molnupiravir could be the first oral antiviral medicine for Covid-19.
Merck and Ridgeback’s Investigational Oral Antiviral Molnupiravir Reduced the Risk of Hospitalization or Death by Approximately 50 Percent Compared to Placebo for Patients with Mild or Moderate COVID-19 in Positive Interim Analysis of Phase 3 Study
At the Interim Analysis, 7.3 Percent of Patients Who Received Molnupiravir Were Hospitalized Through Day 29, Compared With 14.1 Percent of Placebo-Treated Patients Who were Hospitalized or Died
…………
molnupiravir (MK-4482, EIDD-2801), an investigational oral antiviral medicine, significantly reduced the risk of hospitalization or death at a planned interim analysis of the Phase 3 MOVe-OUT trial in at risk, non-hospitalized adult patients with mild-to-moderate COVID-19. At the interim analysis, molnupiravir reduced the risk of hospitalization or death by approximately 50%; 7.3% of patients who received molnupiravir were either hospitalized or died through Day 29 following randomization (28/385), compared with 14.1% of placebo-treated patients (53/377); p=0.0012. Through Day 29, no deaths were reported in patients who received molnupiravir, as compared to 8 deaths in patients who received placebo. At the recommendation of an independent Data Monitoring Committee and in consultation with the U.S. Food and Drug Administration (FDA), recruitment into the study is being stopped early due to these positive results. Merck plans to submit an application for Emergency Use Authorization (EUA) to the U.S. FDA as soon as possible based on these findings and plans to submit marketing applications to other regulatory bodies worldwide.
………
Eligibility criteria required that all patients had laboratory-confirmed mild-to-moderate COVID-19, with symptom onset within 5 days of study randomization. All patients were required to have at least one risk factor associated with poor disease outcome at study entry. Molnupiravir reduced the risk of hospitalization and/or death across all key subgroups; efficacy was not affected by timing of symptom onset or underlying risk factor. Additionally, based on the participants with available viral sequencing data (approximately 40% of participants), molnupiravir demonstrated consistent efficacy across viral variants Gamma, Delta, and Mu.
The incidence of any adverse event was comparable in the molnupiravir and placebo groups (35% and 40%, respectively). Similarly, the incidence of drug-related adverse events was also comparable (12% and 11%, respectively). Fewer subjects discontinued study therapy due to an adverse event in the molnupiravir group (1.3%) compared to the placebo group (3.4%).

About Merck’s Efforts to Enable Access to Molnupiravir, if it is Granted EUA or Approval
In anticipation of the results from MOVe-OUT, Merck has been producing molnupiravir at risk. Merck expects to produce 10 million courses of treatment by the end of 2021, with more doses expected to be produced in 2022.
In April 2020, a whistleblower complaint by former Head of US Biomedical Advanced Research and Development Authority (BARDA) Rick Bright revealed concerns over providing funding for the further development of molnupiravir due to similar drugs having mutagenic (DNA damaging) properties.[4] A previous company, Pharmasset, that had investigated the drug's active ingredient had abandoned it.[5] These claims were denied by George Painter, CEO of DRIVE, noting that toxicity studies on molnupiravir had been carried out and data provided to regulators in the US and UK, who permitted safety studies in humans to move forward in the spring of 2020. Also at this time, DRIVE and Ridgeback Biotherapeutics stated they planned future safety studies in animals.[6]

Safety controversy[edit]
In April 2020, a whistleblower complaint by former Head of US Biomedical Advanced Research and Development Authority (BARDA) Rick Bright revealed concerns over providing funding for the further development of molnupiravir due to similar drugs having mutagenic (DNA damaging) properties.[4] A previous company, Pharmasset, that had investigated the drug's active ingredient had abandoned it.[5] These claims were denied by George Painter, CEO of DRIVE, noting that toxicity studies on molnupiravir had been carried out and data provided to regulators in the US and UK, who permitted safety studies in humans to move forward in the spring of 2020.
