  • Valneva to Partner with Instituto Butantan on Single-Shot Chikungunya Vaccine for Low- and Middle- Income Countries
    VALNEVA SE Campus Bio-Ouest | 6, Rue Alain Bombard 44800 Saint-Herblain, France Valneva to Partner with Instituto Butantan on Single-Shot Chikungunya Vaccine for Low- and Middle- Income Countries Saint-Herblain (France), Sao Paulo, (Brazil), May 5, 2020 – Valneva SE (“Valneva” or “the Company”), a specialty vaccine company, and Instituto Butantan, producer of immunobiologic products, today announced the signing of a binding term sheet for the development, manufacturing and marketing of Valneva’s single-shot chikungunya vaccine, VLA1553, in Low and Middle Income Countries (LMICs). The collaboration falls within the framework of the $23.4 million in funding Valneva received from the Coalition for Epidemic Preparedness Innovations (CEPI) in July 20191. The definitive agreements are expected to be finalized in the next six months. After the signing of the definitive agreements, Valneva will transfer its chikungunya vaccine technology to Instituto Butantan, who will develop, manufacture and commercialize the vaccine in LMICs. In addition, Instituto Butantan will provide certain clinical and Phase 4 observational studies that Valneva will use to meet regulatory requirements. The agreement will include small upfront and technology transfer milestones. Valneva held its End of Phase 2 meeting with the U.S. Food and Drug Administration (FDA) in February 2020 and is now preparing to initiate Phase 3 clinical studies in the U.S. later this year. Thomas Lingelbach, Chief Executive Officer of Valneva, commented, “Although millions of people have been affected by chikungunya, there is currently no vaccine and no effective treatment available against this debilitating disease. We look forward to working with Instituto Butantan to help address this current public health crisis and speed up the development of a chikungunya vaccine in LMICs, which are high outbreak areas."

Since then, no significant changes in the legislative authority under which NIH operates overseas have taken place. Consequently, NIH objectives continue to be the ones formulated in Section 2, paragraph one, of the International Health Research Act of 1960 (P. L. 86-610): "To advance the status of the health sciences in the United States and thereby the health of the American people through cooperative en- deavors with the other countries in health re- search, and research training." It is important to keep this fact in mind in discussing the various activities undertaken by NIH in relation to Latin America.

  • A Representative GIIA Phospholipase A2 Activates Preadipocytes to Produce Inflammatory Mediators Implicated in Obesity Development

Received: 11 September 2020; Accepted: 18 November 2020; Published: 24 November 2020 Abstract: Adipose tissue secretes proinflammatory mediators which promote systemic and adipose tissue inflammation seen in obesity. Group IIA (GIIA)-secreted phospholipase A2 (sPLA2) enzymes are found to be elevated in plasma and adipose tissue from obese patients and are active during inflammation, generating proinflammatory mediators, including prostaglandin E2 (PGE2). PGE2 exerts anti-lipolytic actions and increases triacylglycerol levels in adipose tissue. However, the inflammatory actions of GIIA sPLA2s in adipose tissue cells and mechanisms leading to increased PGE2 levels in these cells are unclear. This study investigates the ability of a representative GIIA sPLA2, MT-III, to activate proinflammatory responses in preadipocytes, focusing on the biosynthesis of prostaglandins, adipocytokines and mechanisms involved in these effects. Our results showed that MT-III induced biosynthesis of PGE2, PGI2, MCP-1, IL-6 and gene expression of leptin and adiponectin in preadipocytes.
