The cost of the drug to you cannot be determined by the retail cost. For example, the 12 pill cure for Hepatitis C retails for $130,000.00 . Medicare, assuming you carry both parts and a supplemental covers the entire cost minus your normal deductible, whatever that is for you.
Next, it is a misnomer to say it is for the newly diagnosed. It apparently has been shown to be effective in people who can still perform many/ most activities of daily living. That is a broad interpretation and includes many slow progressors like my husband as well as some but not all of the newly diagnosed.
Let's remember this is new, and few have discussed it with their Doctors yet. I am about the farthest thing from a chirpy optimist on the nightmare horror show that is ALS but I don't want to discount this drug right out of the gate either. Personally I feel a lot more inspired by the idea of new meds than opportunities to participate in clinical trials, essential as those are to finding the cure/ effective treatment.
