Ensuring the safety of our patients is our utmost priority. We want you to know that we are closely monitoring the COVID- 19 situation and taking steps to keep everyone as safe as possible. At this time, in order to protect the safety of our patients and preserve our ability to staff our sites with our talented specialty doctors and teams, ENTA will be limiting patient access at several clinical locations.
