Gilead Submits NDA for Remdesivir as COVID-19 Treatment
Gilead Sciences has submitted a new drug application (NDA) to the US Food and Drug Administration for Veklury (remdesivir), an investigational antiviral for the treatment of COVID-19.

Veklury is currently available in the US under an emergency use authorization for the treatment of hospitalized patients with severe COVID-19. The filing is the final tier of a rolling NDA submission that was initiated on April 8, 2020.

The filing is supported by data from two randomized, open-label, multi-center Phase III clinical studies of Veklury conducted by Gilead and a Phase III randomized, placebo-controlled study of Veklury conducted by the National Institute of Allergy and Infectious Diseases. These studies demonstrated that treatment with Veklury led to faster time to recovery compared with placebo and that a five-day or 10-day treatment duration led to similar clinical improvement, according to information from the company. Across studies, Veklury was generally well-tolerated in both the five-day and 10-day treatment groups, with no new safety signals identified, according to the company.

Veklury has been approved by multiple regulatory authorities globally, including in the European Union and Japan.

Novavax, Serum Institute of India in Pact for COVID-19 Vaccine
Novavax, a Gaithersburg, Maryland-based clinical-stage vaccine company, has formed a license agreement with Serum Institute of India (SII), a Pune, Maharashtra, India-based vaccine manufacturer, for the development and commercialization of NVX‑CoV2373, Novavax’s COVID‑19 vaccine candidate, in low- and middle-income countries (LMIC) and India.

This agreement excludes major upper-middle and high-income countries, for which Novavax continues to retain rights. NVX‑CoV2373 is a stable, prefusion protein made using Novavax’s recombinant protein nanoparticle technology and includes Novavax’s proprietary saponin-based adjuvant, Matrix‑M.

For LMICs and India, Novavax and SII are partnering on clinical development, co-formulation, filling and finishing and commercialization of NVX-CoV2373. SII will be responsible for regulatory submissions and marketing authorizations. Novavax will provide to SII both vaccine antigen and its Matrix‑M adjuvant, and Novavax and SII are in discussions to have SII manufacture the vaccine antigen in India. Novavax and SII will split the revenue from the sale of product, net of agreed costs.

This agreement further boosts the gl bal supply of the NVX-CoV2373 vaccine and builds on Novavax’s collaboration with the Coalition for Epidemic Preparedness Innovations (CEPI), a public–private coalition focused on vaccine development against emerging infectious diseases. Through that partnership with CEPI, Novavax has committed to develop and manufacture significant amounts of NVX-CoV2373, if proved safe and effective.

Last week (August 7, 2020), SII entered into a partnership with Gavi, a global public health partnership, and the Bill & Melinda Gates Foundation to accelerate the manufacture and delivery of up to 100 million doses of COVID-19 vaccines for LMICs. The funding will support at-risk manufacturing by SII for candidate vaccines from AstraZeneca and Novavax, which will be available for procurement if they are successful in attaining full licensure and prequalification from the World Health Organization. This provides upfront capital to SII to help increase manufacturing capacity so that once a vaccine(s) gains regulatory approval and WHO prequalification, doses can be produced at scale for distribution to India and LMIC as part of the COVID-19 Vaccine Global Access (COVAX) Facility, a mechanism established by Gavi for a globally fair allocation framework, as early as the first half of 2021.

SII has set a ceiling price for vaccine(s) of $3 per dose. The arrangement also provides an option to secure additional doses if the vaccines pillar of the Access to COVID-19 Tools (ACT) Accelerator, a global collaboration of governments, scientists, businesses, civil society, and philanthropists and global health organizations, including the WHO, CEPI and the Bill & Melinda Gates Foundation, involved in diagnostics, vaccines, and treatments for COVID-19, sees a need for it.

Novavax, SK bioscience in Pact for Novavax’s COVID-19 Vaccine Candidate
Novavax, a Gaithersburg, Maryland-based clinical-stage vaccine company, and SK bioscience, a Pangyo, Gyeonggi, South Korea-headquartered biopharmaceutical company that specializes in vaccines and a subsidiary of SK Chemical, have announced a development and supply agreement for the antigen component of NVX-CoV2373, Novavax’s COVID-19 vaccine candidate, for supply to global markets including the COVID-19 Vaccine Global Access (COVAX) Facility.

In addition, the companies have signed a letter of intent with the Republic of Korea’s Ministry of Health and Welfare to work toward broad and equitable access to NVX-CoV2373 for the global market as well as to make the vaccine available in South Korea.

Under the terms of the agreement, SK bioscience will manufacture the vaccine antigen component for use in the final drug product globally during the pandemic period. SK bioscience, using its cell culture and recombinant protein capability, will initiate the production of the NVX-CoV2373 antigen at its vaccine facility in Andong L-house, South Korea beginning in August 2020.

This contract development and manufacturing organization agreement uses the capacity reservation agreement between SK bioscience and the Coalition for Epidemic Preparedness Innovations (CEPI), a public–private coalition that seeks to derail epidemics by speeding up the development of vaccines. Novavax’s NVX-CoV2373 will be manufactured using a part of the reserved capacity at SK Bioscience’s “L-House” facility.

This agreement further boosts the potential global supply of the NVX-CoV2373 vaccine and is an important component of Novavax’s collaboration with CEPI. Through that partnership with CEPI, Novavax has committed to develop and manufacture significant amounts of NVX-CoV2373, including vaccine derived from antigen coming from SK bioscience, if proved safe and effective, to be procured and distributed by the COVAX Facility through a globally fair allocation framework.

NVX-CoV2373 was developed using Novavax’s recombinant nanoparticle technology to generate a stable, prefusion antigen derived from the coronavirus spike (S) protein. It contains Novavax’s saponin-based Matrix-M adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies. Phase I data from the company’s Phase I/II randomized, observer-blinded, placebo-controlled trial shows that NVX-CoV2373 was generally well-tolerated and elicited robust antibody responses numerically superior to that seen in human convalescent sera.
