Our Unique Approach
We are advancing the next generation of oligonucleotide therapeutics with the goal of transforming the treatment of severe neuromuscular and neurologic diseases. Our Enhanced Delivery Oligonucleotide (EDO) platform leverages cell-penetrating peptide conjugates to improve the activity and tolerability of oligonucleotide cargo therapeutics.
Peptides are molecules made of linked amino acids; they are commonly found in nature and play many roles in the body. Our innovative, proprietary EDO peptides are engineered for optimal tissue and cell penetration, and they have demonstrated the ability to transport oligonucleotides into a broad range of target tissues, including smooth, skeletal and cardiac muscle, and the CNS.
Using our EDO peptides, we are generating a pipeline of oligonucleotide therapies that target the root cause of serious neuromuscular diseases. Our mission is to deliver transformative therapeutics to those in need and our innovative technology is well-positioned to effect this change for patients, families and the broader healthcare community.
Oligonucleotide therapeutics are a genetic medicine modality that can target the root cause of many diseases through the modulation of RNA expression and processing. However, despite the considerable potential of these therapies, the development of oligonucleotide therapeutics has been limited by challenges in their delivery. On their own, oligonucleotide therapeutics are not readily distributed to heart and skeletal muscle, the key affected tissues in neuromuscular diseases like Duchenne muscular dystrophy (DMD), and myotonic dystrophy type 1 (DM1) and are not efficiently taken up into these cells.
PepGen’s Solution: Our Enhanced Delivery Oligonucleotide Platform
To address this challenge, we engineered our proprietary EDO technology to optimize tissue and cell penetration, which we believe may result in the enhanced therapeutic activity and improved tolerability of oligonucleotide therapies. Our platform is based on novel cell-penetrating EDO peptides that were developed through an iterative process that selected simultaneously for high uptake; biodistribution to key muscle targets, including cardiac tissue; and improved tolerability.
Our lead product candidates in DMD and DM1 utilize one of these optimized, proprietary, novel EDO peptides, and we are continuing to build and develop this platform technology as we expand into new therapeutic areas.
