Ice, juice, the exact measure of liquor, a few drops of Angostura... What goes into a good New Year’s Eve cocktail? According to researchers working on vaccines for the most elusive viruses, it will be time soon to toast next-generation vaccines. If 2020 was the year of the COVID-19 pandemic, and in 2021 the year of mRNA vaccinations, 2022 brought polyvalent designs of antigens, evaluated highly neutralizing antibodies, and fine-tuned mRNA technology against SARS-CoV-2, HIV and the flu.
Jiangsu Recbio Technology Co. Ltd. released phase II data showing its recombinant two-component COVID-19 vaccine Recov appeared more effective than Comirnaty (tozinameran), the mRNA vaccine developed by Biontech SE and Pfizer Inc., as a booster for users of inactivated vaccines.
Ethris GmbH has entered into a collaboration with Diosynvax Ltd. to jointly develop a protective mRNA vaccine candidate against a broad range of betacoronaviruses utilizing the company's highly differentiated mRNA modification and design technologies as well as its lipidoid nanoparticle (LNP) and stabilization platforms.
Everest Medicines Ltd. has achieved a preclinical proof-of-concept milestone for its mRNA rabies vaccine program. This new vaccine candidate for rabies post-exposure prophylaxis was developed in partnership with Providence Therapeutics Holdings Inc. utilizing a clinically validated mRNA technology platform.
Pfizer Inc. and Biontech SE have initiated a phase I study to evaluate the safety, tolerability and immunogenicity of BNT-162b4, a next-generation COVID-19 vaccine candidate that aims to enhance SARS-CoV-2 T-cell responses and potentially broaden protection against COVID-19.
CSL Ltd. subsidiary CSL Seqirus signed a licensing and development deal with Arcturus Therapeutics Inc. to in-license Arcturus’ late-stage self-amplifying mRNA vaccine platform technology. Arcturus will receive $200 million up front and is eligible to receive more than $1.3 billion in development milestones and over $3 billion in commercial milestones.
CSL Ltd. subsidiary CSL Seqirus signed a licensing and development deal with Arcturus Therapeutics Inc. to in-license Arcturus’ late-stage self-amplifying mRNA vaccine platform technology. Arcturus will receive $200 million up front and is eligible to receive more than $1.3 billion in development milestones and over $3 billion in commercial milestones. In addition, it could capture a 40% net profit share for COVID-19 vaccines and up to double-digit royalties for vaccines against flu, pandemic preparedness and three other respiratory pathogens.
Arcturus Therapeutics Inc. has obtained an award for up to US$63.2 million from the Biomedical Advanced Research and Development Authority (BARDA) to expand its current influenza vaccine program to include development of a pandemic influenza vaccine based on its proprietary self-amplifying mRNA platform.
Moderna Inc. has received conditional authorization from the U.K.’s Medicines and Healthcare Products Regulatory Agency for its bivalent COVID-19 booster vaccine mRNA-1273.214 (Spikevax bivalent original/omicron). The conditional approval, which covers adults aged 18 years and older, marks a new phase in the ongoing global effort to curb the COVID-19 pandemic, as the new vaccine represents the first commercial product to incorporate omicron-specific epitopes. It contains 25 micrograms each of the spike proteins of the omicron BA.1 variant and the original Wuhan strain of SARS-CoV-2.
Arcturus Therapeutics Holdings Inc. reported that ARCT-154, its self-amplifying mRNA COVID-19 vaccine, showed efficacy of 55% against infection and 95% efficacy against severe disease, meeting the primary and key secondary endpoints of the ongoing phase I/II/III trial. While the company’s stock (NASDAQ:ARCT) regained much of its initial 25% drop to close the day, investors continue to await further data to determine where Arcturus’ vaccine will fit in with available COVID-19 vaccines.
