Nikolai Sopko

Chief Scientific Officer & VP R&D, PolarityTE

We have worked with Dr. Sigal and his team at Angel City Research in all three of our randomized controlled trials evaluating chronic wounds including our current pre-market pivotal RCT for BLA approval. They have consistently been one of our top enrolling sites and produce high quality data, which we have successfully used to open our IND and receive RMAT designation. Dr. Sigal and the Angel City Research team are professional, timely, and courteous and a pleasure to work with.
