On the results of the current study and the benefit in the no-thrombolysis group, Dr. Hankey stated: “Although this result might be a chance finding or confounded by the indication for alteplase, complementary pharmacokinetic data in a small number of patients treated with nerinetide showed that alteplase lowered plasma concentrations of nerinetide, probably by converting plasminogen to plasmin, which cleaves peptide bonds not only in fibrin but also in the eicosapeptide nerinetide.”
He said the ESCAPE-NA1 trial “informs the study of cytoprotection as an adjunct therapy to reperfusion in acute ischemic stroke” and suggested that researchers who have reported encouraging results of other cytoprotective therapies for ischemic stroke should test their compounds for interactions with concurrent thrombolytic therapies.
The ESCAPE-NA1 trial was sponsored by NoNO, the company developing nerinetide. Dr. Hill has received grants from NoNO for the conduct of the study, is named on a U.S. patent for systems and methods for assisting in decision making and triaging for acute stroke patients, and owns stock in Calgary Scientific. Other coauthors are employees of NoNO or have stock options in the company. Dr. Hankey has received personal honoraria from the American Heart Association, AC Immune, Bayer, Bristol-Myers Squibb, and Medscape outside the area of work that he commented on.
