Wound Healing

PEP promotes accelerated growth of dermal progenitors and blood vessels while reducing oxidative free radicals and inflammation to drive full thickness healing of chronic ischemic wounds. Revascularization and rapid healing has been demonstrated in preclinical animal studies. The ClinicalTrials.gov identifier for this study is NCT04664738.

Acute Myocardial Infarction

PEP is the first off-the-shelf regenerative exosome designed for intravascular delivery for heart attack patients. It is designed to be administered seamlessly with established stent deployment and cardiac procedures. Its long-term viability has been shown in preclinical models to promote new blood vessel growth, cell recruitment and cell survival, ultimately leading to reduced scarring and improved heart function. The ClinicalTrials.gov identifier for this study is NCT04327635.

Fistulizing Diseases

Rion is developing PEP to treat fistulas that arise as a complication of surgery and certain inflammatory diseases. This serious condition currently has limited treatment options and represents a major unmet need.

bg

Urinary Incontinence

PEP has the potential to reverse stress urinary incontinence in women with pelvic floor disorder. PEP therapy has been shown in preclinical animal models to accelerate epithelialization, neovascularization, and skeletal muscle restoration.

Additional Indications

Rion is continuing to evaluate PEP for other indications where tissue regeneration is needed and current standards of care are insufficient.
