Sanofi and Glaxo Collaborate to Develop Coronavirus Vaccine

Read MoreHide Full Article

Sanofi (SNY - Free Report) and GlaxoSmithKline (GSK - Free Report) , two of the world’s largest vaccines companies, have come together to accelerate the development of a novel vaccine to fight the global pandemic, COVID-19 caused by coronavirus. The companies have signed a letter of intent for developing an adjuvanted vaccine for COVID-19.

Adjuvant vaccines are created by adding an adjuvant to a vaccine, which leads to enhancement of immune response and demonstrate stronger and longer-lasting immunity against infections than the vaccine alone. An adjuvant vaccine may also support the delivery of an effective vaccine that can be manufactured at large scale.

The companies plan to initiate a phase I study on the coronavirus vaccine candidate in the second half of 2020. The vaccine if successfully developed will be available in the second half of 2021.

To make the vaccine, Sanofi will contribute the S-protein COVID-19 antigen developed using its recombinant DNA technology, which has helped produce an exact genetic match to proteins found on the surface of the virus. The company is using its technology for developing a coronavirus vaccine candidate, which is the basis of its licensed recombinant influenza product in the United States.

Meanwhile, Glaxo will provide its proven pandemic adjuvant technology for the development of the coronavirus vaccine candidate. This technology may reduce the amount of vaccine protein required per dose, which, in turn, will allow more vaccine doses to be produced.

Proven technologies of these leading companies may lead to a better and scalable coronavirus vaccine, which is the need of the hour. However, the vaccine is likely to be available after at leasta year from now, which is a significant amount of time, given the speed at which the infection has spread from China to more than 180 countries in a span of three months, affecting nearly 2 million people.

Shares of Sanofi and Glaxo have declined 8.4% and 14%, respectively, so far this year compared with the industry’s decrease of 7.1%.

We note that Sanofi has a collaboration with the Biomedical Advanced Research and Development Authority (“BARDA”) related to the development of coronavirus vaccine. BARDA is funding the development of its recombinant-based COVID-19 vaccine candidate, under the agreement. Meanwhile, the company has also collaborated with Translate Bio (TBIO - Free Report) to develop an mRNA-based vaccine for coronavirus infection. The company is also evaluating its rheumatoid arthritis drug, Kevzara, in collaboration with Regeneron to treat patients hospitalized with severe infection due to COVID-19.

Please note that several pharma/biotech companies are engaged in developing vaccines or treatments for the coronavirus infection. Moderna (MRNA - Free Report) is one of the leading players in this field and is evaluating its mRNA-based vaccine in a phase I study. Pharma giant, J&J has announced plans to initiate a clinical study to evaluate its potential coronavirus vaccine candidate in September. However, all vaccine developments are in pre-clinical or early-stage development.
