Drug Farm bags $56M to take novel hepatitis B drug into humans Fierce Pharma

Drug Farm has raised $56 million to take its lead hepatitis B treatment into the clinic. The series A round will equip Drug Farm to start learning whether its mutagenesis-based approach to drug target discovery translates into effective therapies.

Sino-American biotech Drug Farm is built on a way to generate libraries of genetic mutations in mice and analyze the animals for insights into potential drug targets linked to host immunity. Tian Xu, Ph.D., founder and chair of Drug Farm, and his collaborators published an overview of their approach to genomewide, phenotype-driven mutagenesis in PNAS in 2019.

Drug Farm has used the platform to create a pipeline led by a treatment for hepatitis B infection. The drug candidate, DF-006, is a first-in-class, orally bioavailable small molecule that is on the cusp of the clinic.

“We have successfully leveraged our forward genetics technology, piggyBac transposon mutagenesis to discover new targets, connect them to diseases and advance candidates toward clinical development,” Xu said in a statement. “Using our deep learning AI technology, we have been able to rapidly develop small molecule drugs against these targets, with an initial focus on HBV.”

With human trials on the horizon, Drug Farm has tapped investors for $56 million to fund the work. Investors in Drug Farm include BioVeda China Fund, WuXi AppTec’s corporate venture fund, South China Venture Capital, Detong Capital and Zhejiang United Investment Group.

The human studies will provide early evidence of whether DF-006 can contribute to a push to better treat hepatitis B that has attracted companies including Johnson & Johnson and Roche. Companies are coming at the challenge from multiple angles, but Drug Farm thinks it has struck upon a novel way of treating infections.

Drug Farm is applying its platform to other liver diseases as well as to cancer and a rare form of blindness. Work on those indications is at an earlier stage than the hepatitis B program, which will serve as a proving ground for Drug Farm’s approach to target discovery.

Pfizer said an updated version of its COVID-19 vaccine will be 'ready in 100 days' if the new Omicron variant is resistant to its current vaccine

Pfizer said it will be able to manufacture and distribute an updated version of its COVID-19 vaccine within 100 days if the new variant Omicron is found to be resistant to its current vaccine. Scientists first detected the new variant in South Africa. It has since spread to several other countries, including Israel and Belgium, prompting a spate of travel restrictions across Europe, Asia, and North America , Insider's Aria Bendix reported . A health official said on Saturday that two cases of the variant have been detected in the UK . The variant itself has multiple mutations that might make it easier for it to evade antibodies that developed in the body after receiving a COVID-19 vaccine. The mutations might also cause the variant to spread easily — even among vaccinated people . The World Health Organization has labeled Omicron a " variant of concern ," a distinction given to the most threatening coronavirus variants. Delta, the v...

Texas governor bans vaccine passports from being required in state ABC News

Thats Right States like Texas and Florida got the Vaccine Passport Conspiracy from Del Bigtree. https://abc7.com/politics/texas-governor-bans-vaccine-passport-requirement-in-state/10491161/ AUSTIN, Texas -- Gov. Greg Abbott issued an executive order Tuesday morning prohibiting state agencies or political subdivisions in Texas from creating a "vaccine passport" requirement. Conversation has grown around vaccine passports recently as an option that can be used for travel or even eating out . They are typically described as an app with a code that verifies if someone has been vaccinated or recently tested negative for COVID-19. They're already in use in Israel, and in development in parts of Europe. But Abbott shut that down as an option in the Lone Star State with Executive Order No. GA - 35 also prohibiting "organizations receiving public funds from requiring consumers to provide documentation of vaccine status in order to receive any service or enter any place....
