CEO Update: BriLife Investigational Vaccine and Omicron Variant Effectiveness

As reported last night in the Times of Israel, the former Director of the Israel Institute for Biological Research (IIBR) disclosed that the BriLife™ Vaccine has shown initial signs of effectiveness against the Omicron variant.

This is the information that caused NRx to advise the public that we are moving towards a vanguard trial of BriLife as a booster vaccination for people who previously received mRNA vaccines. We are advised that the scientific data will be released sometime next week.

The important part is not so much that BriLife demonstrated effectiveness against Omicron. The virus is mutating more rapidly than the more familiar influenza viruses, and changing the way it looks inside our bodies, how sick it makes us and how it changes the way we fall ill. The key issue from our perspective is that Omicron looks very different to the immune system than the original virus. Recent studies in Israel and elsewhere have demonstrated disappointing results when repeated mRNA vaccination (i.e., a fourth mRNA vaccination) was tried in the face of the Omicron surge.

We know, for example, that the Delta variant made many very sick and infected a person’s entire respiratory system. We then quickly saw the Omicron variant sweep across our world and become the dominant variant. While it did not cause the same level of severe illness in the majority of people, we now know Omicron is significantly more transmittable than any other mutation of the virus and that the Omicron variant infects people much easier than the original wildtype virus or COVID-19 mutations that have infected humans since the late part of 2019.

At NRx, we continue to keep up with how mutations of the COVID-19 virus and its mutations impact human health.

The news of BriLife’s effectiveness comes from Dr. Shmuel Shapira, the former Director of the IIBR, NRx’s partner in developing the BriLife vaccine. As with many important data regarding vaccine and medicine development, the complete and detailed information is expected to be published in a scientific journal in the coming weeks.

NRx continues to work with the IIBR to design a Phase 3 trial to test the BriLife vaccine as a booster and looks forward to generating important data that may show a different and more comprehensive level of protection against COVID-19 and its variants.

As always, I will continue to share information as it becomes available and provide updates about our efforts to bring the BriLife vaccine to the market and information about our other investigational medicines and their ability to protect us from illness and help us regain our health.

As always, thank you for following our journey.
