In one of the biggest financings of the year so far, former Prometheus Biosciences Inc. CEO Mark McKenna helped raise $400 million to launch a new company, Mirador Therapeutics Inc. He didn’t sit on the sidelines for long after Merck & Co. Inc. bought Prometheus for $10.8 billion in 2023. He recruited key Prometheus executives to focus on Mirador’s genetic approach to drug discovery and precision medicine. McKenna said there was too much left undone to just hang back. In this BioWorld Insider episode, he talks about the new company and the multi-billion-dollar drugs that he believes provide sub-optimal efficacy compared to the tailor-made therapies he wants to develop. He also has deep insights into drug pricing and why the investment market is so tough on companies that don’t have A-plus science and teams.
