We are committed, both individually and collectively, to unlocking the full potential of genetic medicine.

Our pioneering platform has the potential to extend the power of gene therapy to many more diseases, affecting many more people, than what is possible with existing gene therapy technology. We are advancing a broad and expansive portfolio in both rare and prevalent diseases.

Initially, we are focusing on diseases of the liver and retina with great unmet need and for which our non-viral gene therapy platform may significantly improve patients' lives. We plan to expand into additional rare and prevalent diseases of the liver and retina, as well as in skeletal muscle, the central nervous system and oncology. We also plan to advance antibody gene therapy programs where we see a possibility of directing the body’s own cells to produce consistent levels of therapeutic antibodies for years at a time from a single dose.

Liver

Phenylketonuria (PKU)
PKU is a rare autosomal recessive genetic disorder caused by deficiency of the hepatic enzyme phenylalanine hydroxylase. This enzyme metabolizes the essential amino acid phenylalanine, or Phe. Since Phe is found in all protein containing foods, eating a normal diet with PKU leads to elevated levels of Phe in the blood, and toxic Phe accumulation in the brain. This results in symptoms like skin rashes, neurological problems including intellectual disability, and behavioral, social and emotional issues. We aim to achieve stable correction of Phe levels in PKU patients of all ages, which may allow them to have more normal diets, eliminate the burden of ongoing treatment and stabilize and/or preserve neurocognitive function. PKU affects approximately 15,000 individuals in the United States and 41,000 in the EU.
Hemophilia A
Hemophilia A is a rare X-linked hereditary bleeding disorder in which the blood does not clot properly. It is a result of deficiency in the production or function of coagulation Factor VIII. We aim to titrate dosing of our ceDNA therapy to achieve individualized therapeutic Factor VIII levels for each child and adult, restoring normal clotting function, preventing or reducing the risk of bleeding episodes and potentially eliminating the need for recurring Factor VIII injections. Hemophilia A affects approximately 16,000 individuals in the United States and 320,000 individuals worldwide.
Wilson Disease
Wilson disease is a rare autosomal recessive disease due to a loss-of-function mutation in the ATB7B copper transporter. We aim to achieve full hepatic correction of copper metabolism early in the disease by delivering the full-length ATP7B gene with an optimized expression cassette, re-directing copper to be incorporated into ceruloplasmin and normalizing bile excretion. This offers the potential to overcome liver fibrosis and prevent irreversible neurocognitive decline.
There are approximately 11,000 individuals with Wilson disease in the United States and 17,000 in the EU.
Gaucher Disease
Gaucher disease is a rare inherited autosomal recessive disorder caused by the insufficient expression of lysosomal enzyme glucocerebrosidase, or GCase. Gaucher disease is the most common inherited lysosomal storage disease. We aim to treat early in the disease, before the onset of inflammation, fibrosis and irreversible tissue injury and to provide consistent GCase expression levels, with the potential to significantly reduce the treatment burden relative to enzyme replacement therapy (ERT) infusions.
There are approximately 6,000 individuals with Gaucher disease in the United States and 9,000 in the EU.
Antibody Gene Therapy
Our antibody gene therapy program seeks to deliver to the liver the genes needed to produce specific antibodies. With a single dose, our non-viral gene therapy platform may enable durable secretion of antibodies to provide consistent therapeutic effects over time. We aim to advance antibody gene therapy programs across multiple therapeutic areas.

Retina

Leber’s Congenital Amaurosis 10 (LCA10)
LCA10 is the most common genetic cause of childhood vision loss. We aim to treat all LCA10 patients, irrespective of their CEP290 mutation, utilizing ctLNP to specifically deliver durable CEP290 expression to photoreceptors, potentially recovering visual function for patients with a one-time treatment.
LCA10 affects approximately 2,200 individuals in the United States and 3,400 in the EU.
Stargardt Disease
Stargardt disease is the most common inherited macular dystrophy. We aim to deliver the full ABCA4 gene to photoreceptors and RPE cells and halt the progressive loss of retinal rods/cones to preserve vision.
Stargardt disease affects approximately 37,000 individuals in the United States and 66,000 in the EU.
Wet Age-Related Macular Degeneration (wet AMD)
AMD is the leading cause of vision loss occurring in approximately 10 million people in the United States. Wet AMD is the most severe form of AMD, characterized by neovascularization of the retina, leading to significant loss in visual acuity and rapid progression to blindness. We aim to deliver intravitreally to enable retinal cells to sustainably produce and secrete anti-VEGF. This may enhance regression of neovascularization and improve visual acuity and may also enable administration only a few times over the life of a patient, while reducing lapses in treatment coverage.
There are approximately 1.2 million individuals with wet AMD in the United States and 2.5 million in the EU.

Expansion Areas

Skeletal Muscle
There are a variety of genetic muscle disorders, including muscular dystrophies, that may be treated by efficient and systemic gene therapy to skeletal muscle. We are currently developing a ctLNP utilizing a targeting ligand to deliver ceDNA specifically to skeletal muscle.
Central Nervous System (CNS)
We are exploring the use of ceDNA to correct disorders of the CNS. The work we are doing with local delivery in the retina to photoreceptors may inform expansion into the CNS.
Oncology
We are exploring the use of ceDNA to treat a variety of cancer indications. We believe that we can use distinct targeting ligands to deliver ceDNA specifically and efficiently to tumors and can utilize ceDNA to express high levels of relevant proteins within the tumor.
