The FDA should approve the protocol in a timely manner. With 18 sites there's a very good chance we have enrollment complete by mid-April. If the FDA allows us to use the results of the current mechanically ventilated critically ill patients then the protocol would be set for 28 days. I think there's a very good chance at EUA by early June. With a reduced number of patients , a very narrow set of patients and a very narrow protocol analysis should be more timely.
