About Parallel Bio
Using the immune system to cure disease
Parallel Bio created a human 'immune system in a dish' to discover drugs and immunotherapies more likely to work in patients. Our platform has all of the same elements as a human immune system, meaning you can test drugs and vaccines as if you were testing them in actual patients from the start. The biggest reason why 95% of new drugs fail is that they were tested in mice - but with our human platform, pharma companies will know which drugs will successfully treat patients, speeding up the process and reducing the cost. To date our platform has successfully been used to test 12 drugs, and vaccines against 8 different diseases. The company is founded by Robert DiFazio, a former Stanford R&D director with a PhD in immunology, and Juliana Hilliard, a former System1 Biosciences R&D lead with an MSc in bioengineering, both of whom have led drug discovery programs for years.
