Clinical trials

ST266 is a non-cellular biologic drug candidate, currently considered “investigational,” since it is not yet approved by the U.S. Food and Drug Administration (FDA). Our clinical trials are designed to examine and confirm that ST266 is safe and effective in humans with the goal of bringing this unique product to potentially millions of patients who suffer from complex diseases and conditions in ophthalmology, neurology, dermatology—and beyond.

ST266 is made by our proprietary method of culturing amnion epithelial cells that are harvested from donated full-term placentas normally discarded after birth. It contains hundreds of biologically active proteins and other factors crucial to neuroprotection, the modulation of inflammation, cell recovery and healing. These various proteins and factors are delivered in physiologic concentrations that have been shown, in preclinical and clinical studies to date, to be well-tolerated with demonstrated biologic activity.

In clinical trials, 270 patients have been administered St266 by topical dermal, topical oral, topical ocular, intravenous, and targeted intranasal delivery with no reported drug-related serious adverse events.

Enrollment in one of our clinical trials is the only way we can provide access to our investigational drugs prior to their FDA approval. Patients who choose to participate in a clinical trial are playing an important role in helping advance new medical breakthroughs.
