Ann: DMC Completes Final Review of Phase 3 Heart Failure Trial, page-6

In their interim futility analysis by the same independent DMC announced on 10 April 2017, they determined that the trial has met the pre-specified primary endpoint and have recommended the trial to be continued.

IMHO, I read it correctly it means the 270 patients were reacting positively and showing statiscally significance improvements - note here this is half of the population involved in the trial. Otherwise, the trial would have been terminated back then.

So the likelihood of a successful trial in demonstrating primaryendpoint of reduction in heart failure-related hospital admissions, and in the key secondary endpointof reduction in cardiac deaths is high.
