They were treated with three Gray of whole brain radiation daily for 10 days, with or without efaproxiral delivered by a central venous access device.
The finding contrasts with an earlier study that had seemed to show a benefit for women who got efaproxiral combined with whole-brain radiation, according to John Suh, M.D., of the Cleveland Clinic.
At three months, confirmed complete response and partial responses were seen in 31\% of efaproxiral patients and in 27\% of those in the control arm, but the difference was not significant.
