Merck has largely stayed out of the COVID-19 battle, but exploded into it with three major deals and collaborations today. First, Merck is buying Austria-based Themis, a vaccines and immune-modulation therapies company focused on infectious diseases and cancer. Merck hasn’t disclosed financial details, except that it is a cash deal to buy all outstanding Themis shares.

Themis has a pipeline of vaccine candidates and immune-modulatory therapies that it has built using its measles virus vector platform. The vector was originally developed by researchers at the Institut Pasteur and licensed exclusively to Themis for specific viral indications. In March, the company joined a consortium with the Institut Pasteur and The Center for Vaccine Research at the University of Pittsburgh, which is supported by monies from the Coalition for Epidemic Preparedness Innovations (CEPI), to develop a vaccine candidate against COVID-19. “Building on the pioneering work of the Institute Pasteur, the Themis team has established specialized expertise that complements Merck’s own capabilities in the discovery, development, manufacturing and global distribution of vaccines,” said Roger M. Perlmutter, president, Merck Research Laboratories. “We are eager to combine our strengths both to develop an effective COVID-19 vaccine in the near term and to build a pandemic preparedness capability directed toward emerging agents that pose a future epidemic threat.”

Secondly, Merck is collaborating with IAVI, a nonprofit scientific research organization focused on global health challenges. They are partnering to develop a vaccine against COVID-19. The vaccine candidate uses the recombinant vesicular stomatitis virus (rVSV) technology that was used for Merck’s Ebola Zaire virus vaccine, ERVEBO. Merck has also entered an agreement with the Biomedical Advanced Research and Development Authority (BARDA), part of the office of the Assistant Secretary for Preparedness and Response within the U.S. Department of Health and Human Services (HSS)....

The French vaccine developer Valneva has received a €21M ($23.4M) grant to catch up with the competition in commercializing the first potential vaccine for the chikungunya virus. Coming from the nonprofit Coalition for Epidemic Preparedness Innovations (CEPI), the grant will boost the manufacturing and development of Valneva’s vaccine for the tropical disease chikungunya, which causes fever and can trigger chronic pain in the joints. Chikungunya has long been a problem in developing countries with endemic tropical diseases, but has received less attention from developed countries until recently. However, climate change could increase the range of disease-carrying mosquitoes, and chikungunga outbreaks in Europe could become more common. Companies developing vaccines for the disease could deliver an important weapon in the fight against the disease. 

In May, the vaccine showed the potential to protect against the virus in a phase I trial. As the company has already calculated an optimal dose, Valneva’s one-shot vaccine could skip phase II and head directly to phase III.

The Austrian biotech Themis Bioscience is also developing a vaccine for chikungunya, which is expected to enter phase III later this year. With a phase III trial expected to begin in early 2020, Valneva might narrow Themis’ lead in the race to get the first chikungunya vaccine to the market. 

The CEPI allocates grants to fund the development of vaccines against infections causing humanitarian crises. CEPI also recently provided a 19M euros grant to Themis, with the aim of accelerating vaccines for chikungunya and other diseases to the market.
