Sex hormone progesterone to get head injury trial
Natural progesterone, the sex hormone used in the first contraceptive pills, is to be tested on patients with severe head injuries.
Scientists will begin a phase III clinical trial in March and say the drug could save patients' lives and reduce damage to their brains.
They announced the trial at the annual meeting of the American Association for the Advancement of Science.
It will involve 1,000 patients in 17 trauma centres across the US.
Dr David Wright, associate professor of emergency medicine at Emory University in Atlanta, will lead the trial.
