COVID-19 Vaccine Moderna Intramuscular Injection (TAK-919) Description

The COVID-19 Vaccine Moderna Intramuscular Injection is an mRNA vaccine targeted against the SARS-CoV-2 coronavirus encoding for a prefusion stabilized form of the Spike (S) protein authorized for use in Japan on May 21, 2021.

Japan's Ministry of Health, Labour, and Welfare (MHLW) granted special approval under Article 14-3 of the Pharmaceuticals and Medical Devices Act for the emergency use of Moderna’s mRNA COVID-19 vaccine, which is authorized for emergency use in adults aged 18 years and older.

Japan's approval results from a three-way agreement announced in October 2020 with Moderna and the Government of Japan’s MHLW to distribute 50 million doses of TAK-919 in Japan in the first half of 2021.

The approval is based on Moderna’s Phase 3 COVE study results and positive initial clinical data from the Takeda-led placebo-controlled Phase 1/2 study. This study is designed to evaluate the safety and immunogenicity of two vaccinations of COVID-19 Vaccine Moderna Intramuscular Injection at the 100 μg dose level given 28 days apart in 200 participants aged 20 years and above in Japan. Initial results showed an immune response with results from Moderna’s Phase 3 COVE study conducted in the U.S. Binding and neutralizing antibody titers were elevated 28 days after the second dose of the Moderna COVID-19 vaccine candidate in 100% of participants. The vaccine candidate was generally well tolerated with no significant safety concerns reported. Participants will be followed through 12 months after the second vaccination.
