    In this episode of Raising Biotech, Surani delves into Arialys and its mission to revive an autoimmune encephalitis drug from the grave after big pharma no longer wanted it. The company founders are a bunch of venture capitalists (Avalon Ventures, MPM Capital & Catalys Pacific) who saw potential in pursuing the preclinical drug candidate -- raising a $58 million seed financing in September 2023 to take it into human testing.Surani speaks to CEO Jay Lichter (Avalon) about his background, success stories, how he stumbled across Astellas' drug (now ART5803) and why he was so impressed with preclinical data in non-human primate marmoset models. Marty Jefson, CEO of Pinteon Therapeutics, a veteran neuropsychiatry drug development executive, talks about the drug's potential to fit in the treatment paradigm and what convinced him to join the company's clinical advisory board.

  • 3. 3. eGenesis and xenotransplantation with CEO Mike Curtis and Dr Adam Griesemer, NYU

    In this episode of Raising Biotech, Surani Fernando speaks with eGenesis CEO Mike Curtis on its mission to create pig donor organs for humans waiting for a transplant. The company has raised $263 million over the last 6 years and is now raising further funds to start human clinical trials.Surani speaks to Mike about the company's history overcoming past Xenotransplantation challenges and using CRISPR Cas9 to finalize their platform -- which conducts 69 edits in the pig genome for optimal compatibility and safety in humans. After recent data (Nature) showed a maximum survival of a monkey surviving with a pig kidney for over 2 years, the company is talking to regulators to enter clinical trials and in parallel is talking to investors and potential partners to take its programs forward. As the company enters unchartered territory, all future strategic business options are on the table. Dr Adam Griesemer, associate professor of surgery at Grossman School of Medicine, NYU Langone Health, gives his take on the unmet need and progress of Xenotransplanation and eGenesis' scientific thesis of 69 gene edits.
