Consultants who weren’t concerned within the examine mentioned the information was encouraging, however that necessary unanswered questions remained concerning the potential remedy. One unknown is what profit the drug would have in comparison with sufferers who by no means obtained it in any respect and obtained solely placebo for 30 months, mentioned Dr. Robert Miller, director of scientific analysis at Forbes Norris MDA/A.L.S. Analysis Heart at California Pacific Medical Heart. Nonetheless, he mentioned he thought-about the outcomes a “base hit single.”

However, he mentioned, it wasn’t clear how a lot those that first obtained 24 weeks of placebo benefited once they took the drug. “It may imply that the drug is actually efficient and individuals who bought the drug late actually would have been lifeless at 12 months as an alternative of 18,” Dr. Koroshetz mentioned. “Or, the opposite mind-set about it’s that the drug will not be efficient until you get it early. There’s no clue right here to which a type of is true.”
