Treating chronic disease by using novel biomaterials to keep implanted cells hidden from the immune system

Sigilon Therapeutics is developing improved treatments for chronic diseases using a novel type of therapeutic: implanted cells shielded by proprietary biomaterials from immune attack and the foreign body response (fibrosis). Treatments based on the Sigilon Therapeutics technology platform are designed to act as responsive “living therapeutics” that can provide more natural control for diseases which are currently treated with intermittent injection or infusion.

It was the discovery of novel biomaterials called Afibromers™ that prompted the founding of Sigilon Therapeutics. When cells are enclosed in Afibromer™ coated capsules, they are invisible to the immune system and do not trigger fibrosis—the scarring response that the body uses to isolate foreign bodies and which is responsible for nutrient deprivation and cell necrosis. The company’s proprietary cells are engineered to secrete therapeutic proteins and, in combination with the Afibromer™ technology, these implanted cells are hidden from the immune system. As a result, levels of the missing protein in the body can be restored for long periods of time following a single intervention.

Sigilon’s cell-driven therapeutics are designed to have advantages over traditional biologic therapies, including the restoration of protein levels at a constant rate, years of therapy without need for re-dosing, safe and reversible therapeutic modality, the delivery of proteins for previously untreatable diseases and more. These advantages can provide significant clinical outcome benefits and free patients from therapies that disrupt their quality of life.

Initial therapeutic areas of interest include diabetes and blood disorders

While Sigilon is confident its therapy could help patients with a variety of diseases that require chronic dosing of a biologic, the company has started by focusing on areas that will provide the most significant benefits for patients balanced with the shortest path to approval. These initial target areas include diabetes, blood disorders and lysosomal storage disorders.
