I hope they can get this to people quickly. Someone I love has been diagnosed with stage 3 end of Feb this year and it's utter hell. For everyone, not just the patient.
Of course this is better than nothing, but it is not a cure.
Moreover, the link provided by another poster to an article that discusses the side effects, shows that they are unpleasant.
Still, an extra year of life may provide a chance to survive until the appearance of a better solution.
Therefore those well above the median might have reached an extra year of life.
I agree however that because almost all of them (96%) had severe side effects, many people would prefer to not choose this kind of life extension.
My own parents were such people.
