- RION has entered a collaboration with Lonza for the cGMP manufacture of its Purified Exosome Product™ (PEP™) drug substance.
- The agreement covers late-phase clinical supply and potential commercial-scale production at Lonza’s Houston facility.

RION, a commercial and clinical-stage regenerative medicine company, has signed a collaboration with Lonza, one of the world’s largest contract development and manufacturing organisations (CDMOs). The partnership will focus on cGMP manufacturing and technical support for RION’s Purified Exosome Product™ (PEP™) drug substance.
Under the agreement, Lonza will manufacture PEP™ drug substance at its Houston facility in the United States. The arrangement is designed to provide late-phase clinical supply and future commercial-scale production, supported by Lonza’s expertise in extracellular vesicles.
RION has developed a proprietary biomanufacturing platform enabling scaled production of platelet-derived exosomes. The technology underpins its pipeline of therapeutics across multiple indications, including advanced tissue regeneration, dermatology, musculoskeletal disease, pulmonary disease, cardiovascular health and women’s health.
PEP™ is formulated as a lyophilised powder with immunomodulatory, anti-inflammatory, and tissue regenerative properties. It can be administered through several routes, allowing application across a wide range of clinical areas.
“This collaboration with Lonza ensures that our proprietary exosome manufacturing platform can be scaled to meet clinical and future commercial demand,”.
