- Phase 1 investigator-initiated trial evaluating the safety of intradermally injected Purified Exosome Product™ (PEP™) in healthy adults
- Rion Aesthetics, a regenerative aesthetics company, provides investigational product and research support
- Trial intended to generate safety data and support future scientific exploration
ROCHESTER, Minn.--(BUSINESS WIRE)--Rion Aesthetics, an internationally recognized regenerative aesthetics company, today announced that the U.S. Food and Drug Administration (FDA) has allowed an Investigational New Drug (IND) application to proceed for a Phase 1 investigator-initiated trial evaluating Purified Exosome Product™ (PEP™) injected into the dermis. The study is sponsored and independently conducted by Clinical Testing Center of Beverly Hills and is being led by Dr. John H. Joseph, a double board-certified facial plastic surgeon based in California.




PEP™, a shelf-stable lyophilized powder derived from human platelets, is an investigational product, developed by RION, a clinical-stage regenerative medicine company. PEP™ is being evaluated in research for its potential effects on cellular processes relating to tissue repair, including cell growth, angiogenesis, inflammation modulation, and cellular protection.
The investigator-initiated trial will evaluate the safety and tolerability of PEP™ when injected intradermally into healthy adults undergoing planned elective abdominoplasty surgery. Rion Aesthetics is providing PEP™, the investigational product, and research support for this independent trial. Following FDA allowance of the IND application, dosing of the first participants began this month.
“This trial marks an important step in expanding the scientific understanding of PEP™ exosomes,” said Alisa Lask, CEO of Rion Aesthetics. “We’re proud to support independent scientific research into PEP™ as part of our commitment to advancing innovation in regenerative aesthetics.”
The study (NCT06429033) is a Phase 1 clinical trial that will enroll up to nine healthy adult participants undergoing abdominoplasty surgery. This trial is designed to evaluate the safety and tolerability of intradermally administered, platelet-derived PEP™ exosomes in healthy volunteers. Additional endpoints will include tissue analyses to assess PEP™’s regenerative potential on biological markers such as collagen and elastin.
