Manufacturing and supply of COVID-19 vaccines and drugs

Pfizer, BioNTech To Supply EU with 100 M Doses of COVID-19 Vaccine
Pfizer and BioNTech, a Mainz, Germany-based immunotherapy company, report that they will supply an additional 100 million doses of Comirnaty, the companies’ COVID-19 vaccine, to the 27 member states in the European Union (EU) in 2021.

This announcement is a result of the European Commission’s (EC) decision to exercise its option to purchase an additional 100 million doses under its advanced purchase agreement signed on November 11, 2020. This agreement brings the total number of doses to be delivered to the EU to 300 million. Comirnaty was granted conditional marketing authorization by the European Medicines Agency (EMA) in December 2020 in people 16 years of age and older.

Comirnaty will be produced in BioNTech’s and Pfizer’s manufacturing sites in Europe. The distribution of Comirnaty by EU member states will continue to be determined according to the populations identified in EU and national guidance. Pfizer and BioNTech announced on November 11, 2020 that they reached an agreement with the EC to supply 200 million doses, with an option for the EC to request an additional 100 million doses. The companies previously stated their potential to supply up to 1.3 billion doses globally by the end of 2021 (subject to manufacturing capacity).

Merck & Co. US Gov’t in Supply Pact for Initial Doses of COVID-19 Therapy
Merck & Co. has entered into an agreement with the US government to support the development, manufacture, and initial distribution of an investigational biological therapeutic for treating COVID-19, subject to the approval or emergency use authorization (EUA) of the drug from the US Food and Drug Administration (FDA).

The drug, MK-7110, was acquired by Merck from OncoImmune, a Rockville, Maryland-based clinical-stage biopharmaceutical company, in a $475-million deal that was announced last year (November 2020).

Under the agreement with the US government, Merck will receive up to approximately $356 million for the manufacturing and supply of approximately 60,000 to 100,000 doses of MK-7110 to the US government through June 30, 2021 to meet the government’s goals of Operation Warp Speed, a US initiative to speed the development and distribution of COVID-19 vaccines and treatments. The company says this approach is intended to expedite delivery of MK-7110, following potential EUA or FDA approval. Merck is also investing to expand its manufacturing capacity to increase supply of MK-7110.

In September 2020, OncoImmune reported findings from an interim efficacy analysis of a Phase III study evaluating MK-7110 for treating severe and critical COVID-19. An interim analysis from 203 participants indicated that hospitalized patients with COVID-19 treated with a single dose of MK-7110 showed a 60% higher probability of improvement in clinical status compared to placebo. The risk of death or respiratory failure was reduced by more than 50%. The study is ongoing.

MK-7110 is a recombinant fusion protein that targets the innate immune system. In addition to the Phase III clinical trial for COVID-19 patients, MK-7110 has been studied for safety in healthy volunteers and in Phase II clinical trials for the prevention of graft versus host disease (GVHD) following hematopoietic stem-cell transplantation in patients with leukemia. A Phase III clinical trial for prophylaxis of GVHD has been initiated nationwide.

Updates on COVID-19 treatments and vaccines

AstraZeneca’s COVID-19 Vaccine Gets OK in India, Other Countries
AstraZeneca’s and the University of Oxford’s COVID-19 vaccine has been granted emergency use authorization in India, Argentina, the Dominican Republic, El Salvador, Mexico and Morocco for the active immunization of adults.

AstraZeneca has partnered with the Serum Institute of India, a vaccine manufacturer, for the supply of the vaccine to the Indian government and to a large number of low- and middle-income countries.

In the European Union, AstraZeneca has submitted a data package to support a conditional marketing authorization for its COVID-19 vaccine to the European Medicines Agency (EMA) as part of an ongoing rolling review process and will continue to work with the EMA to seek authorization in the coming weeks (as reported on January 6, 2021). AstraZeneca is also seeking an emergency use listing from the World Health Organization for an accelerated pathway to vaccine availability in low-income countries and has ongoing rolling reviews with other global regulatory authorities.

In addition to the University of Oxford-led trials, the company is conducting a large trial in the US as part of a global program. In total, the University of Oxford and AstraZeneca expect to enroll more than 60,000 participants globally. Additional safety and efficacy data will continue to accumulate from ongoing clinical trials.

In addition, AstraZeneca is working with its global partners to continue building manufacturing capacity of up to three billion doses of the vaccine globally in 2021 on a rolling basis, pending regulatory approvals.

The vaccine is an adenovirus vector-based vaccine licensed by AstraZeneca from Oxford University and is being jointly developed. It was co-invented by the University of Oxford and its spin-out company, Vaccitech. It uses a replication-deficient chimpanzee viral vector based on a weakened version of a common cold virus (adenovirus) that causes infections in chimpanzees and contains the genetic material of the SARS-CoV-2 virus spike protein. After vaccination, the surface spike protein is produced, priming the immune system to attack the SARS-CoV-2 virus, the virus that causes COVID-19, if it later infects the body.

Regeneron Reports Positive Initial Data of COVID-19 Antibody Cocktail Trial
Regeneron Pharmaceuticals, a Tarrytown, New York-based biopharmaceutical company, has reported initial data from an ongoing Phase I/II/III clinical trial of its antibody cocktail consisting of casirivimab and imdevimab in hospitalized COVID-19 patients requiring low-flow oxygen.

The analysis was prospectively designed to focus on patients who had not yet mounted their own immune response to SARS-CoV-2, the virus that causes COVID-19. The primary clinical objective of this initial analysis was to determine whether there was sufficient efficacy in these patients to warrant continuing the trial. The results passed the futility analysis, as seronegative patients treated with the antibody cocktail had a lower risk of death or receiving mechanical ventilation.

In November 2020, Regeneron’s antibody cocktail was granted an emergency use authorization (EUA) by the US Food and Drug Administration (FDA) in high-risk patients who have confirmed COVID-19 but are not currently hospitalized. The EUA is temporary and does not take the place of a formal biologics license application (BLA) submission, review and approval process.

Emergent, Mount Sinai Initiate Clinical Program for COVID-19 Candidate
Emergent BioSolutions, a Gaithersburg, Maryland-based specialty biopharmaceutical company and contract manufacturer, and Mount Sinai Health System, a New York-based hospital and medical research system, have initiated a clinical program to evaluate Emergent’s COVID-19 treatment, human hyperimmune globulin (COVID-HIG), in the first of two Phase I studies.

The studies will evaluate its use for potential post-exposure prophylaxis in individuals at high risk of exposure to SARS-CoV-2, the virus that causes COVID-19. The first study will evaluate the safety and pharmacokinetics of three dose levels administered as a single or repeat IV dose in healthy adults. The second study, once initiated, will evaluate the safety, pharmacokinetics, and pharmacodynamics of two dose levels administered as a single IV dose to adults with SARS-CoV-2 infection, whether asymptomatic or with mild COVID-19.

The existing plasma collection capabilities at Mount Sinai established through its collaboration with Emergent and ImmunoTek Bio Centers, a Lafayette, Louisiana-based company procuring and collecting human blood plasma, has enabled ongoing plasma collection from recovered donors to support the development and manufacture of COVID-HIG for evaluation in clinical trials. The clinical research program, including a planned Phase II study, is designed to assess whether prophylaxis with COVID-HIG could help protect individuals following high-risk exposure to SARS-CoV-2.

The US Department of Defense’s (DoD) Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense has provided $34.6 million in funding in support of this program. In addition to receiving DoD& funding to advance a post-exposure prophylaxis indication for COVID-HIG, Emergent was awarded $14.5 million in April 2020 by the US Department of Health and Human Services (HHS) to develop COVID-HIG as a potential treatment for COVID-19. Emergent’s proprietary COVID-HIG product candidate is also being evaluated in a Phase III clinical study initiated in October 2020 by the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, as a potential treatment in hospitalized patients. Mount Sinai serves as a study site.
