What do you mean that the course will be longer? Do you mean that they are going to carry the trials on for longer than they initially said ie to the summertime 2015 ? or do you mean that people are going to be taking the pills for longer than 4 weeks? and do you know anything about the hearing test getting easier or not? and the person you got this from is someone reliable who knows what he or she is saying? the person is actually in charge of running the trial? thanks
