Innorna receives IND clearance for its first-in-class bivalent RSV mRNA vaccine in China

IN006, a bivalent RSV vaccine developed by Innorna's proprietary mRNA-LNP technology, has broad-spectrum potency against both the A and B subgroups of RSV.

UNITED STATES, June 13, 2024 /EINPresswire.com/ -- Innorna, a clinical-stage biotech company pioneering its proprietary lipid nanoparticle (LNP) technology to develop novel mRNA vaccines and therapeutics, is delighted to announce a significant regulatory milestone. Its first-in-class bivalent Respiratory Syncytial Virus (RSV) mRNA vaccine, IN006, has received Investigational New Drug (IND) clearance from the National Medical Products Administration (NMPA) in China (https://www.cde.org.cn/main/xxgk/listpage/9f9c74c73e0f8f56a8bfbc646055026d, reference number CXSL2400187). This is a crucial step for Innorna in bringing this innovative vaccine to the Chinese market and making a global impact on the prevention and control of RSV-related diseases.

IN006, a bivalent RSV prophylactic vaccine product developed by Innorna based on its proprietary mRNA-LNP technology platform, was designed to code stable prefusion F proteins and has broad-spectrum potency against both A and B subgroups of RSV (two mRNAs’ encapsulated in one LNP) compared to the marketed monovalent vaccines. IN006 received IND clearance from the U.S. FDA in January 2024. The IND clearance from China's NMPA marks another important milestone for IN006. It is the first non-COVID-19 mRNA prophylactic vaccine approved for clinical trials in China.

"We are delighted to receive IND approval for IN006 from the NMPA. We will accelerate its clinical development to provide more effective measures to prevent and control RSV-related diseases worldwide," affirmed Linxian Li, Ph.D., CEO and Founder of Innorna.

About RSV and IN006

Respiratory syncytial virus (RSV) is a common respiratory virus with two major subtypes, A and B. RSV is highly contagious and can lead to outbreaks in communities and hospitals. There are still possibilities of re-infection with RSV in people who have been infected. Children under the age of five, adults over 65 years of age, or the immunocompromised population are at high risk of severe manifestation and exacerbation of chronic diseases. Currently, only supportive care and symptomatic treatment are available in clinical settings, and there is still a lack of specific anti-RSV therapy. Therefore, active immunization via vaccination is crucial to avoid severe manifestations of RSV infection and reduce case fatality.

After decades of research and development, only two recombinant protein vaccines against RSV were approved in the market by 2023, including AREXVY^® (monovalent) from GlaxoSmithKline and ABRYSVO^® (bivalent) from Pfizer. Moderna's RSV mRNA vaccine, mRESVIA^® (monovalent), was approved in the United States in May 2024. There is no RSV vaccine currently approved in China.

IN006 uses Innorna's proprietary prefusion F protein design and LNP delivery system. This bivalent mRNA vaccine targets RSV subgroups A and B, which usually alternate or circulate simultaneously during the individual season. In preclinical studies, IN006 has demonstrated a well-tolerated safety profile and a high potency to induce immune response and protect animals from viral infection, offering a promising solution to the global health challenge of RSV.
