Aurora Therapeutics, a new startup co-founded by Nobel Prize-winning scientist Jennifer Doudna, is working on tailored gene-editing treatments for rare diseases. The company plans to use a novel FDA regulatory pathway that allows personalized treatments for rare and fatal diseases based on data from just a handful of patients.
The current process for approving new drugs requires testing in hundreds or thousands of patients, which can be difficult for rare diseases due to the small number of affected individuals. However, this new pathway, known as the "plausible mechanism pathway," provides an alternative route for these types of treatments to get regulatory approval.
Aurora is initially focusing on treating a metabolic disorder called phenylketonuria (PKU), which affects 13,500 people in the US and requires a highly restrictive low-protein diet. The company aims to develop multiple versions of a PKU therapy that address different mutations using base editing, a more precise form of Crispr.
The development of personalized gene-editing therapies is crucial for patients like baby KJ, who recently received treatment made just for him after just six months. The treatment likely saved his life and was approved using the new regulatory pathway.
Aurora's strategy involves swapping out the guide RNA to make several versions of a PKU therapy that address different mutations, allowing the company to use the same technology platform to treat many mutations with less regulatory red tape.
The Innovative Genomics Institute will continue to create bespoke gene-editing therapies for children with very rare diseases. A trial at the Children's Hospital of Philadelphia and Penn Medicine will test the same type of gene editor used in baby KJ's therapy in a group of similar disorders.
Industry expert Fyodor Urnov believes that Crispr technology is finally maturing, and he predicts that we will see other children with their personalized editors within three to four years.
