Generation Bio

Generation Bio is a biotechnology company developing non-viral genetic medicines for rare and prevalent diseases. The company's proprietary platform combines immune-quiet DNA (iqDNA), a novel variant of closed-ended DNA, with a cell-targeted lipid nanoparticle (ctLNP) delivery system and a rapid enzymatic synthesis (RES) manufacturing process. This platform is designed to create gene therapies with drug-like properties, offering durable gene expression, the ability to re-dose for individual patient titration, and the potential to sustain effect over a lifetime. Generation Bio's approach aims to enable multi-year durability from a single dose, deliver large genetic payloads, and allow titration and redosing to adjust or extend expression levels in each patient. The company's pipeline includes programs for liver diseases such as hemophilia A, phenylketonuria (PKU), and Wilson's disease, as well as eye disorders like Stargardt disease and Leber congenital amaurosis type 10. In October 2023, Generation Bio announced the development of iqDNA, which demonstrated cytokine levels and tolerability comparable to chemically modified messenger RNA in mice and non-human primates. Generation Bio's RES manufacturing process has the potential to produce ceDNA at a scale of hundreds of millions of doses.

Key customers and partnerships

In March 2023, Generation Bio entered into a strategic partnership with Moderna to develop non-viral genetic medicines. The collaboration combines Moderna's expertise with Generation Bio's platform technologies to expand their respective non-viral genetic medicines pipelines. Under this partnership, Moderna is using Generation Bio's ctLNP delivery system and iqDNA technology to advance two immune cell programs and two liver programs. The deal included a USD 40 million upfront cash payment and a USD 36 million equity investment from Moderna. Generation Bio will also receive future development, regulatory, and commercial milestone payments, along with royalties on worldwide net sales of immune cell-targeted and liver-targeted products. The partnership aims to develop new lipid nanoparticles and expand in vivo immune cell targeting as a new class of genetic medicines.
