Phase 3 MOVe-OUT Study of Molnupiravir in Outpatients to Proceed, Phase 2/3 MOVe-IN Study in Hospitalized Patients Will Not Proceed

Merck (NYSE: MRK), known as MSD outside the United States and Canada, and Ridgeback Biotherapeutics today provided an update on the clinical development program for molnupiravir (MK-4482/ EIDD-2801), an investigational orally available antiviral therapeutic. Based on a planned interim analysis of data from the Phase 2, dose-finding portion (Part 1) of two ongoing placebo-controlled Phase 2/3 trials evaluating molnupiravir administered twice a day for five days in outpatients (MOVe-OUT) and hospitalized patients (MOVe-IN) with COVID-19, and from a previously completed Phase 2a dose-ranging study in outpatients, the decision has been made to proceed with the Phase 3 portion (Part 2) of MOVe-OUT in outpatients with COVID-19, evaluating the 800 mg dose of molnupiravir twice daily. Data from MOVe-IN indicate that molnupiravir is unlikely to demonstrate a clinical benefit in hospitalized patients, who generally had a longer duration of symptoms prior to study entry; therefore, the decision has been made not to proceed to Phase 3.

"We continue to make progress in the clinical development of our antiviral candidate molnupiravir. Data from the dose-finding portion of these studies are consistent with the mechanism of action and provide meaningful evidence for the antiviral potential of the 800 mg dose," said Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories. "Based on the findings of this study we are advancing a Phase 3 trial program in non-hospitalized patients that strategically leverages our large network of clinical sites to enroll appropriate patients globally."

"We are pleased that molnupiravir continues to show promise as a potential treatment for non-hospitalized patients with COVID-19," said Wendy Holman, Chief Executive Officer, Ridgeback Biotherapeutics. "Data from Ridgeback Bio's EIDD-2801-2003 study (MK-4482-006) coupled with Merck's MK-4482-002 study provide compelling evidence for the antiviral activity of molnupiravir. We look forward to the initiation and completion of the Phase 3 portion of the MOVe-OUT study."

Update on MOVe-OUT (MK-4482-002) and MOVe-IN (MK-4482-001)

MOVe-OUT is an ongoing Phase 2/3, randomized, placebo-controlled, double-blind, multi-site study evaluating the efficacy, safety and pharmacokinetics of orally administered molnupiravir in non-hospitalized participants with COVID-19 confirmed using polymerase chain reaction. The primary efficacy objective of MOVe-OUT is to evaluate the efficacy of molnupiravir compared to placebo as assessed by the percentage of patients who are hospitalized and/or die from the time of randomization through Day 29. Part 1 of MOVe-OUT enrolled a total of 302 participants, with symptom onset within seven days prior to randomization, who were assigned to receive molnupiravir 200 mg (75), 400 mg (77), or 800 mg (76), or placebo (74).

The percentage of patients who were hospitalized and/or died in Part 1 of the MOVe-OUT study was lower in the combined molnupiravir-treated groups versus the placebo arm; the number of events reported are not sufficient to provide a meaningful measure of clinical effect. Analysis of SARS-CoV-2 in nasopharyngeal and oropharyngeal swabs from patients in both MOVe-OUT and MOVe-IN using quantitative and qualitative polymerase chain reaction, an exploratory endpoint, indicated that molnupiravir inhibits replication of the virus, as demonstrated by a greater decrease from baseline in viral RNA compared to placebo at Day 5 and Day 10, and by a larger proportion of participants with undetectable viral RNA at Day 10 and Day 15 following the end of treatment. The largest overall magnitude of antiviral effect was observed in the 800 mg dose compared with the 200 mg and 400 mg doses. These differences in virology endpoints were more pronounced in participants enrolled 5 days following symptom onset.

Among 299 patients who received at least one dose of study intervention in MOVe-OUT, 6.2% (14/225) of those receiving molnupiravir and 6.8% (5/74) of those receiving placebo reported drug-related adverse events. In MOVe-IN, of 293 patients who received at least one dose of study intervention, 11.0% (24/218) of those treated with molnupiravir and 21.3% (16/75) of those receiving placebo reported drug-related adverse events. To date, safety and laboratory data from MOVe-IN and MOVe-OUT provide no evidence for unexpected findings or trends observed at any of the doses studied. In both trials, no deaths were considered drug-related by the investigators, and there were no drug-related adverse events that led to discontinuation in participants who received molnupiravir. Interim results from both MOVe-IN and MOVe-OUT, including virology findings and pharmacokinetic analyses, have been shared with regulatory authorities and will be presented at an upcoming medical meeting.

The external Data Monitoring Committee noted that the subgroup analyses support potential benefit of treatment and suggested amendments to the MOVe-OUT protocol to focus enrollment on patients early in the course of disease and those considered high risk for poor COVID-19 outcomes (e.g., older patients, those with obesity and diabetes). Based upon these recommendations, Merck will amend the inclusion criteria for MOVe-OUT by reducing the allowable symptom duration for enrollment to 5 days and by enrolling participants with at least one risk factor for progression to severe disease. Merck plans to start enrolling patients in Phase 3 portion (Part 2) of MOVe-OUT by late April/early May.

Final data from the Phase 3 portion (Part 2) of the MOVe-OUT study is estimated to be available in September/ October 2021. Merck currently anticipates that, pending favorable results from MOVe-OUT, the earliest possible submission for an Emergency Use Authorization for molnupiravir will be in the second half of 2021. Merck and Ridgeback Biotherapeutics plan to share further findings from the ongoing molnupiravir development program with regulatory agencies as they become available.

In addition, Merck plans to initiate a clinical program to evaluate molnupiravir for post- exposure prophylaxis in the second half of 2021.

About the MOVe-OUT study design

MOVe-OUT (MK-4482-002) is a Phase 2/3, randomized, placebo-controlled, double-blind, multi-site study evaluating the efficacy, safety and pharmacokinetics of orally administered molnupiravir in non-hospitalized participants at least 18 years of age with laboratory confirmed COVID-19 and symptom onset within seven days prior to randomization. The trial plans to enroll a total of 1850 participants with mild or moderate COVID-19. The Phase 2 portion of the trial enrolled 302 participants randomized 1:1:1:1 to receive molnupiravir 200 mg, 400mg, 800mg or placebo twice daily for 5 days. The primary efficacy objective is to evaluate efficacy of molnupiravir compared to placebo as assessed by the percentage of participants who are hospitalized and/or die during the period from randomization through Day 29. Exploratory endpoints supporting dose selection for Phase 3 portion (Part 2) include change from baseline in SARS-CoV-2 RNA plasma levels and percentage of participants with undetectable SARS-CoV-2 RNA various time points, viral RNA mutation rate as assessed by comparison of baseline and post-baseline virus sequencing and pharmacokinetic data (eg, Ctrough, Cmax, tmax, t1/2, AUC0-12). Following the completion of Part 1 the inclusion criteria for MOVe-OUT were amended reducing the allowable symptom duration for enrollment to 5 days and increasing enrollment for those considered high risk for poor COVID-19 outcomes (e.g., older patients and those with obesity and diabetes). For further information regarding the trial please visit clinicaltrials.gov .

About the MOVe-IN study design

MOVe-IN (MK-4482-001) was a Phase 2/3, randomized, placebo-controlled, double-blind, multi-site trial evaluating the efficacy, safety, and pharmacokinetics of orally administered molnupiravir in hospitalized participants at least 18 years of age with laboratory confirmed COVID-19 and symptom onset within 10 days prior to randomization. The Phase 2 portion of the trial enrolled 304 participants randomized 1:1:1:1 to who received molnupiravir 200 mg, 400 mg, 800 mg or placebo twice daily for 5 days. The primary efficacy endpoint was to evaluate the efficacy of molnupiravir compared to placebo as assessed by the rate of sustained recovery from randomization through Day 29. Exploratory endpoints supporting dose selection for the Phase 3 portion (Part 2) of the trial included change from baseline in SARS-CoV-2 RNA levels and percentage of participants with undetectable SARS-CoV-2 RNA at various time points, viral RNA mutation rate as assessed by comparison of baseline and post-baseline virus sequencing and pharmacokinetic data (eg, Ctrough, Cmax, tmax, t1/2, AUC0-12). Following an interim analysis of data, it was concluded that the study was unlikely to demonstrate a clinical benefit in hospitalized patients. The decision was made to discontinue the study.

About Molnupiravir Protocol MK-4482-006 (also known as EIDD-2801-2003)

Protocol 6 (MK-4482-006) is a Phase 2a, double-blind, placebo-controlled, randomized trial designed to compare the safety, tolerability, and antiviral activity of molnupiravir versus placebo as measured by viral RNA detection in symptomatic, outpatient (at baseline) adults at least 18 years old with SARS-CoV-2 infection as confirmed by viral RNA detection within seven days of symptom onset. Of 202 treated participants, molnupiravir was considered generally well tolerated and of the 4 serious adverse events reported, none were considered study drug related. Preliminary data from this study was previously presented at CROI 2021.

About Molnupiravir Nonclinical studies

Merck has conducted a comprehensive nonclinical program to characterize the safety profile of molnupiravir. This program included assays such as Big Blue and PIG-a which are designed to provide a robust measure of a drug or chemical's ability to induce mutations in vivo . Animals were administered molnupiravir for longer and at higher doses (mg/Kg) than those employed in human studies. The totality of the data from these studies indicates that molnupiravir is not mutagenic or genotoxic in in vivo mammalian systems.

About Molnupiravir

Molnupiravir (EIDD-2801/MK-4482) is an investigational, orally administered form of a potent ribonucleoside analog that inhibits the replication of multiple RNA viruses including SARS-CoV-2, the causative agent of COVID-19.

Pfizer and BioNTech Granted U.S. Emergency Use Authorization for Booster Dose of Their COVID-19 Vaccine in Children 5 Through 11 Years of Age

  • EUA is based on data that show children 5 through 11 years of age had a robust immune response with a favorable safety profile following a 10-µg booster dose of the Pfizer-BioNTech COVID-19 Vaccine at a time when Omicron was the prevalent variant
  • Children 5 through 11 years of age now authorized to receive a booster dose at least five months after the second dose of the two-dose primary series
  • To date, 4,500 children 5 through 11 years of age have participated in the companies' COVID-19 vaccine clinical trial

Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced the U.S. Food and Drug Administration (FDA) expanded emergency use authorization (EUA) to include a booster dose after completion of the primary series of the Pfizer-BioNTech COVID-19 Vaccine in children 5 through 11 years of age. The booster dose is given at least five months after the second dose of the two-dose primary series and is the same 10-µg dose of the Pfizer-BioNTech COVID-19 Vaccine. To date, more than 8 million 5- to 11-year-olds in the U.S. have completed a primary series. 1

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20220516005789/en/

The expanded EUA is based on data from the Phase 2/3 clinical trial, which showed that a booster dose of the Pfizer-BioNTech COVID-19 Vaccine elicited a strong immune response in this age group, generating neutralizing antibodies against both the Omicron variant and wild-type SARS-CoV-2 virus regardless of prior SARS-CoV-2 infection. No new safety signals were observed. The third dose was well tolerated, with a safety profile similar to the two-dose primary series.

This Phase 2/3 data builds on efficacy data for the primary two-dose series which showed 90.7% efficacy in children 5 through 11 without prior SARS-CoV-2 infection, measured from 7 days after the second dose, at a period when Delta was the prevalent strain.

The companies have already submitted an application to the European Medicines Agency for a booster dose in this age group and are planning to file with other regulatory agencies around the world. The Pfizer-BioNTech COVID-19 Vaccine is the only COVID-19 vaccine authorized for use in the U.S. for children 5 through 11 years of age.

The Phase 1/2/3 clinical trial evaluating the safety, tolerability, and immunogenicity of a 3-µg formulation of the Pfizer-BioNTech COVID-19 Vaccine on a three-dose schedule in children ages 6 months through 4 years (also known as under 5) is ongoing. Initial data is expected in the coming weeks.

The Pfizer-BioNTech COVID-19 Vaccine, which is based on BioNTech's proprietary mRNA technology, was developed by both BioNTech and Pfizer. BioNTech is the Marketing Authorization Holder in the United States, the European Union, the United Kingdom, Canada and the holder of emergency use authorizations or equivalents in the United States (jointly with Pfizer) and other countries. Submissions to pursue regulatory approvals in those countries where emergency use authorizations or equivalent were initially granted are planned.

About the Phase 1/2/3 Trial in Children

The Phase 1/2/3 trial initially enrolled up to 4,500 children ages 6 months to under 12 years of age in the United States, Finland, Poland, and Spain from more than 90 clinical trial sites. Additional children have been enrolled in all age groups following study amendments and the trial currently includes more than 10,000 children. The trial was originally designed to evaluate the safety, tolerability, and immunogenicity of the Pfizer-BioNTech COVID-19 Vaccine on a two-dose schedule (approximately 21 days apart) in three age groups: ages 5 to under 12 years; ages 2 to under 5 years; and ages 6 months to under 2 years. Based on the Phase 1 dose-escalation portion of the trial, children ages 5 to under 12 years received a two-dose schedule of 10 µg each while children under age 5 received a lower 3-µg dose for each injection in the Phase 2/3 study. The trial enrolled children with or without prior evidence of SARS-CoV-2 infection. In December 2021 , Pfizer and BioNTech announced the companies would test a third 3-µg dose given at least two months after the second dose in children under age 5 and a third dose of the 10-µg formulation in children 5 to under 12 years of age.

The formulation of the Pfizer-BioNTech COVID-19 Vaccine authorized for use in children 5 through 11 years of age differs from the formulations authorized for individuals 12 years of age and older and should therefore not be used interchangeably. The Pfizer-BioNTech COVID-19 Vaccine authorized for use in children 5 through 11 years of age should not be used interchangeably with COMIRNATY® (COVID-19 Vaccine, mRNA).

IMPORTANT SAFETY INFORMATION

Tell your vaccination provider about all of your medical conditions, including if you:

  • have any allergies
  • have had myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the lining outside the heart)
  • have a fever
  • have a bleeding disorder or are on a blood thinner
  • are immunocompromised or are on a medicine that affects the immune system
  • are pregnant, plan to become pregnant, or are breastfeeding
  • have received another COVID-19 vaccine
  • have ever fainted in association with an injection
  • Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY ® (COVID-19 Vaccine, mRNA) may not protect all vaccine recipients
  • You should not receive Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY ® (COVID-19 Vaccine, mRNA) if you have had a severe allergic reaction to any of its ingredients or had a severe allergic reaction to a previous dose of Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY ®
  • There is a remote chance that Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY ® (COVID-19 Vaccine, mRNA) could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to 1 hour after getting a dose of the vaccine. For this reason, your vaccination provider may ask you to stay at the place where you received the vaccine for monitoring after vaccination. If you experience a severe allergic reaction, call 9-1-1 or go to the nearest hospital
    Seek medical attention right away if you have any of the following symptoms:
    • difficulty breathing, swelling of the face and throat, a fast heartbeat, a bad rash all over the body, dizziness, and weakness
  • Myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining outside the heart) have occurred in some people who have received the vaccine, more commonly in males under 40 years of age than among females and older males. In most of these people, symptoms began within a few days following receipt of the second dose of the vaccine. The chance of having this occur is very low
    Seek medical attention right away if you have any of the following symptoms after receiving the vaccine:
    • chest pain
    • shortness of breath
    • feelings of having a fast-beating, fluttering, or pounding heart
  • Fainting can happen after getting injectable vaccines, including Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY ® (COVID-19 Vaccine, mRNA). Sometimes people who faint can fall and hurt themselves. For this reason, your vaccination provider may ask you to sit or lie down for 15 minutes after receiving the vaccine
  • Some people with weakened immune systems may have reduced immune responses to Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY ® (COVID-19 Vaccine, mRNA)
  • Additional side effects include injection site pain; tiredness; headache; muscle pain; chills; joint pain; fever; injection site swelling; injection site redness; nausea; rash; feeling unwell; swollen lymph nodes (lymphadenopathy); decreased appetite; diarrhea; vomiting; arm pain; and fainting in association with injection of the vaccine

These may not be all the possible side effects of the vaccine. Call the vaccination provider or healthcare provider about bothersome side effects or side effects that do not go away.

  • You should always ask your healthcare providers for medical advice about adverse events. Report vaccine side effects to the US Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) Vaccine Adverse Event Reporting System (VAERS). The VAERS toll-free number is 1‐800‐822‐7967 or report online to www.vaers.hhs.gov/reportevent.html .

Risks and uncertainties include, among other things, the uncertainties inherent in research and development, including the ability to meet anticipated clinical endpoints, commencement and/or completion dates for clinical trials, regulatory submission dates, regulatory approval dates and/or launch dates, as well as risks associated with preclinical and clinical data (including Phase 1/2/3 or Phase 4 data) for BNT162b2 or any other vaccine candidate in the BNT162 program in any of our studies in pediatrics, adolescents or adults or real world evidence, including the possibility of unfavorable new preclinical, clinical or safety data and further analyses of existing preclinical, clinical or safety data; the ability to produce comparable clinical or other results, including the rate of vaccine effectiveness and safety and tolerability profile observed to date, in additional analyses of the Phase 3 trial and additional studies, in real world data studies or in larger, more diverse populations following commercialization; the ability of BNT162b2 or any future vaccine to prevent COVID-19 caused by emerging virus variants; the risk that more widespread use of the vaccine will lead to new information about efficacy, safety, or other developments, including the risk of additional adverse reactions, some of which may be serious; the risk that preclinical and clinical trial data are subject to differing interpretations and assessments, including during the peer review/publication process, in the scientific community generally, and by regulatory authorities; whether and when additional data from the BNT162 mRNA vaccine program will be published in scientific journal publications and, if so, when and with what modifications and interpretations; whether regulatory authorities will be satisfied with the design of and results from these and any future preclinical and clinical studies; whether and when submissions to request emergency use or conditional marketing authorizations for BNT162b2 in additional populations, for a potential booster dose for BNT162b2 or any potential future vaccines (including potential future annual boosters or re-vaccinations) and/or other biologics license and/or emergency use authorization applications or amendments to any such applications may be filed in particular jurisdictions for BNT162b2 or any other potential vaccines that may arise from the BNT162 program, including a potential variant based, higher dose, or bivalent vaccine, and if obtained, whether or when such emergency use authorizations or licenses will expire or terminate; whether and when any applications that may be pending or filed for BNT162b2 (including any requested amendments to the emergency use or conditional marketing authorizations) or other vaccines that may result from the BNT162 program may be approved by particular regulatory authorities, which will depend on myriad factors, including making a determination as to whether the vaccine's benefits outweigh its known risks and determination of the vaccine's efficacy and, if approved, whether it will be commercially successful; decisions by regulatory authorities impacting labeling or marketing, manufacturing processes, safety and/or other matters that could affect the availability or commercial potential of a vaccine, including development of products or therapies by other companies; disruptions in the relationships between us and our collaboration partners, clinical trial sites or third-party suppliers; the risk that demand for any products may be reduced or no longer exist; risks related to the availability of raw materials to manufacture a vaccine; challenges related to our vaccine's formulation, dosing schedule and attendant storage, distribution and administration requirements, including risks related to storage and handling after delivery by Pfizer; the risk that we may not be able to successfully develop other vaccine formulations, booster doses or potential future annual boosters or re-vaccinations or new variant based vaccines; the risk that we may not be able to maintain or scale up manufacturing capacity on a timely basis or maintain access to logistics or supply channels commensurate with global demand for our vaccine, which would negatively impact our ability to supply the estimated numbers of doses of our vaccine within the projected time periods as previously indicated; whether and when additional supply agreements will be reached; uncertainties regarding the ability to obtain recommendations from vaccine advisory or technical committees and other public health authorities and uncertainties regarding the commercial impact of any such recommendations; challenges related to public vaccine confidence or awareness; uncertainties regarding the impact of COVID-19 on Pfizer's business, operations and financial results; and competitive developments.

A further description of risks and uncertainties can be found in Pfizer's Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and in its subsequent reports on Form 10-Q, including in the sections thereof captioned "Risk Factors" and "Forward-Looking Information and Factors That May Affect Future Results", as well as in its subsequent reports on Form 8-K, all of which are filed with the U.S. Securities and Exchange Commission and available at www.sec.gov and www.pfizer.com .
