Zapomeran
Zapomeran, sold under the brand name Kostaive is a self-amplifying mRNA-based COVID-19 vaccine. It contains a self-amplifying mRNA that encodes the SARS-CoV-2 spike protein. Self-amplifying means that the mRNA also carries instructions to make a protein called replicase.
It was developed under the name ARCT-154, also known as VBC-COV19-154 in Vietnam, by Arcturus Therapeutics. For its development, Arcturus collaborated with Vinbiocare, a Vietnamese company, for support with clinical trials and manufacturing.
Zapomeran was approved for medical use in Japan in November 2023, and it is the first self-amplifying mRNA-based COVID-19 vaccine to be approved. Zapomeran was authorized for medical use in the European Union in February 2025.
Zapomeran is used to provide protection against COVID-19, caused by infection with the SARS-CoV-2 virus. The vaccine requires two doses, which are administered 28 days apart. It is a self-amplifying mRNA vaccine.
The vaccine candidate can be made in a lyophilized powder form, allowed it to be shipped and stored between 2 and 8 °C (36 and 46 °F).
In August 2021, Arcturus Therapeutics entered a partnership with Vinbiocare, a unit of Vingroup to conduct clinical trials of ARCT-154 COVID-19 vaccine, developed created using Arcturus’ STARR mRNA technology, in Vietnam and establish a manufacturing facility a factory in Hòa Lạc Hi-tech Park, Hanoi, which requires an estimated investment of $200 million and has the capacity to make 200 million doses per year. It is expected that Vingroup will produce its first batches of the vaccine in early 2022. Arcturus will provide to Vinbiocare access to "proprietary technologies and processes for the manufacture" of its vaccines, as well as an exclusive license to manufacture them solely for sales and use in Vietnam. This includes all of Arcturus’ other Covid-19 vaccines such as ARCT-021 and other vaccines in the future for disease prevention in Vietnam. Vinbiocare will pay $40m upfront, be responsible for technology transfer costs, and "pay for mRNA drug substance supplied by Arcturus and royalties on vaccines produced at the facility".
Kostaive was approved for medical use in Japan in November 2023.
In December 2024, the Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Kostaive, a vaccine intended for the prevention of COVID-19 in adults. The applicant for this medicinal product is Arcturus Therapeutics Europe B.V. Zapomeran was authorized for medical use in the European Union in February 2025.
