Novavax Announces Expanded Agreement with SK bioscience to Manufacture COVID-19 Vaccine Containing Omicron Variant and Manufacture the Novavax COVID-19 Vaccine in Prefilled Syringes

GAITHERSBURG, Md., July 19, 2022 /PRNewswire/ -- Novavax, Inc. (Nasdaq: NVAX), a biotechnology company dedicated to developing and commercializing next-generation vaccines for serious infectious diseases, has signed agreements with its partner, SK bioscience, for the manufacturing and supply of a version of the Novavax COVID-19 vaccine (NVX-CoV2373) containing Omicron variant and for the manufacture of the vaccine in prefilled syringes.

The companies signed an agreement for the technology transfer of Novavax' proprietary COVID-19 variant antigen materials so that SK bioscience can manufacture the drug substance targeting COVID-19 variants including the Omicron BA.5 subvariant.

"Non-clinical data generated to date demonstrate that our COVID-19 vaccine offers broad immune responses including against circulating variants, such as Omicron BA.5," said Stanley C. Erck, President and Chief Executive Officer, Novavax. "We are accelerating our clinical program evaluating an Omicron BA.5 component to our vaccine and look forward to continuing to work with SK bioscience as an important manufacturing partner."

In addition, the companies have signed an agreement to manufacture and supply the Novavax COVID-19 vaccine in a prefilled syringe. SK bioscience will begin work to enable the manufacturing process for commercial supply of the vaccine in prefilled syringes in 2023.

Currently, SK bioscience manufactures drug substance for the vaccine. Novavax and SK bioscience also have a collaboration and licensing agreement under which SK bioscience exclusively commercializes the Novavax COVID-19 vaccine in South Korea, and with Novavax, jointly commercializes the vaccine in Vietnam and Thailand.

About the Novavax COVID-19 vaccine (NVX-CoV2373)

The Novavax COVID-19 vaccine (NVX-CoV2373) is a protein-based vaccine engineered from the genetic sequence of the first strain of SARS-CoV-2, the virus that causes COVID-19 disease. The vaccine was created using Novavax' recombinant nanoparticle technology to generate antigen derived from the coronavirus spike (S) protein and is formulated with Novavax' patented saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies. The Novavax COVID-19 vaccine contains purified protein antigen and can neither replicate, nor can it cause COVID-19. 

The Novavax COVID-19 vaccine is packaged as a ready-to-use liquid formulation in a vial containing ten doses. The vaccination regimen calls for two 0.5 ml doses (5 mcg antigen and 50 mcg Matrix-M adjuvant) given intramuscularly 21 days apart. The vaccine is stored at 2°- 8° Celsius, enabling the use of existing vaccine supply and cold chain channels. Use of the vaccine should be in accordance with official recommendations. 

Novavax has established partnerships for the manufacture, commercialization, and distribution of its COVID-19 vaccine worldwide. Existing authorizations leverage Novavax' manufacturing partnership with Serum Institute of India, the world's largest vaccine manufacturer by volume. They will later be supplemented with data from additional manufacturing sites throughout Novavax' global supply chain. 

The Novavax COVID-19 vaccine and the PREVENT-19 trial have been supported in part with federal funds from the U.S. government, including the Department of Health and Human Services (HHS); Office of the Assistant Secretary for Preparedness and Response; Biomedical Advanced Research and Development Authority (BARDA), through the Department of Defense Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND); and the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health at HHS. BARDA is providing up to $1.75 billion under a Department of Defense agreement (# MCDC2011-001). The Department of Defense Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense is also providing funding of up to $45.7 million under a separate agreement. To date, the U.S. government has agreed to order 3.2 million doses of Novavax' vaccine under these existing agreements should it receive a recommendation from the CDC. Novavax and the U.S. government will determine the timing, pricing, and amounts for delivery of any additional doses. Novavax intends to pursue additional U.S. procurement of both its COVID-19 vaccine doses and other potential formulations. 

About the Novavax COVID-19 vaccine (NVX-CoV2373) Phase 3 Trials

The Novavax COVID-19 vaccine (NVX-CoV2373) continues being evaluated in two pivotal Phase 3 trials. 

PREVENT-19 (the PRE-fusion protein subunit Vaccine Efficacy Novavax Trial | COVID-19) is a 2:1 randomized, placebo-controlled, observer-blinded trial to evaluate the efficacy, safety, and immunogenicity of the Novavax COVID-19 vaccine with Matrix-M adjuvant in 29,960 participants 18 years of age and over in 119 locations in the U.S. and Mexico. The primary endpoint for PREVENT-19 was the first occurrence of PCR-confirmed symptomatic (mild, moderate, or severe) COVID-19 with onset at least seven days after the second dose in serologically negative (to SARS-CoV-2) adult participants at baseline. The statistical success criterion included a lower bound of 95% CI >30%. A secondary endpoint was the prevention of PCR-confirmed, symptomatic moderate or severe COVID-19. Both endpoints were assessed at least seven days after the second study vaccination in volunteers who had not been previously infected with SARS-CoV-2. In the trial, the Novavax COVID-19 vaccine achieved 90.4% efficacy overall. It was generally well-tolerated and elicited a robust antibody response after the second dose in both studies. Full results of the trial were published in the New England Journal of Medicine (NEJM). 

The pediatric expansion of PREVENT-19 is a 2:1 randomized, placebo-controlled, observer-blinded trial to evaluate the safety, effectiveness, and efficacy of the Novavax COVID-19 vaccine with Matrix-M adjuvant in 2,247 adolescent participants 12 to 17 years of age in 73 locations in the United States, compared with placebo. In the pediatric trial, the vaccine achieved its primary effectiveness endpoint (non-inferiority of the neutralizing antibody response compared to young adult participants 18 through 25 years of age from PREVENT-19) and demonstrated 80% efficacy overall at a time when the Delta variant of concern was the predominant circulating strain in the U.S. Additionally, immune responses were about two-to-three-fold higher in adolescents than in adults against all variants studied. 

Additionally, a trial conducted in the U.K. with 14,039 participants aged 18 years and over was designed as a randomized, placebo-controlled, observer-blinded study and achieved overall efficacy of 89.7%. The primary endpoint was based on the first occurrence of PCR-confirmed symptomatic (mild, moderate, or severe) COVID-19 with onset at least seven days after the second study vaccination in serologically negative (to SARS-CoV-2) adult participants at baseline. Full results of the trial were published in NEJM. 

About Matrix-M™ Adjuvant

Novavax' patented saponin-based Matrix-M adjuvant has demonstrated a potent and well-tolerated effect by stimulating the entry of antigen-presenting cells into the injection site and enhancing antigen presentation in local lymph nodes, boosting immune response.
