By City News Service Apr 1, 2021 LOS ANGELES (CNS) - A study involving researchers in Los Angeles County, examining whether Trans Sodium Crocetinate protects the threatened brain when given to stroke victims within two hours of an attack, has been closed due to COVID-19 pandemic-related challenges, it was announced today. “We are disappointed that the unexpected national health emergency prevented us from fully testing this potential brain-protecting drug in stroke patients at this time,'' said Dr. Jeffrey Saver, study co-chair and professor of neurology at the David Geffen School of Medicine at UCLA. “The agent remains of great promise and we hope to be able to launch further studies once the pandemic has passed.''
