A parent-led therapy in 2.5 years
Terry Pirovolakis showed what one parent can do: he assembled a research team, raised the funds, and developed a gene replacement therapy for a neurodevelopmental disease in just 2.5 years.
Hope for Jojo
For the first time, a therapy for Jojo and kids like her is within reach, thanks to several recent breakthroughs.
Why now
Terry Pirovolakis showed what one parent can do: he assembled a research team, raised the funds, and developed a gene replacement therapy for a neurodevelopmental disease in just 2.5 years.
The FDA has approved several antisense oligonucleotides (ASOs) for neurological diseases, including one for a genetic form of ALS in 2023.
Researchers at CHOP, Penn, and the Innovative Genomics Institute treated the first patient with a personalized gene-editing treatment, in the liver, developed in just 6 months.
Researchers have already shown that ASOs and gene editing can treat SCN8A in mice.
Jojo's therapy is the next step: taking an approach that has worked in the liver and in mice to the next frontier, the human brain. This is more than one therapy. It's a proof of concept for an approach that can be adapted to treat an entire class of devastating diseases.
The plan
Some steps run in parallel. Timelines and costs are estimates.
We're partnering with the Innovative Genomics Institute (IGI), founded by Nobel laureate Jennifer Doudna, to lead this step. IGI has a pioneering track record: it helped develop the world's first personalized CRISPR treatment, for Baby KJ, who was born with a rare genetic disease.
Scientists design gene therapy candidates and a guide RNA that acts as a GPS, steering the editor to the mutation in Jojo's SCN8A gene. Advanced sequencing checks for unwanted off-target effects.
With the support of Stanford University, Jojo's blood cells are reprogrammed into stem cells (iPSCs) and grown into neurons. Scientists then test the gene therapy on these human neurons to see whether it corrects the SCN8A mutation.
They also run an initial off-target analysis to make sure the editor isn't making unwanted changes to other genes before moving to animals.
A humanized mouse model is created with Jojo's SCN8A variant. Scientists package the gene therapy into a delivery vehicle that can travel to the brain, then give it to the mice to confirm it can be delivered, correct the mutation, and treat the disease.
This step is being run by The Jackson Laboratory (JAX), a leading biomedical research institution known for its mouse models and more than 90 years of genetics research.
To get through the bottlenecks of gene therapy manufacturing, we'll partner with a specialized contract development and manufacturing organization (CDMO). The therapy will be made in an FDA-compliant facility under Good Manufacturing Practice (GMP), so it meets FDA standards for purity, potency, and safety.
Formal, large-scale safety (toxicology) studies are done to Good Laboratory Practice (GLP) standards. This step confirms the therapeutic window and checks that no dangerous toxicity appears in a living system before a child is treated.
Data from every earlier step is compiled into an Investigational New Drug (IND) application and submitted to the FDA. Once the FDA clears it, Jojo can be treated.
