I want to be hopeful. I do believe that drugs like those two have great potential, but there are two main things I get hung up on.
1. Even if these drugs are fabulous, no doctor worth much of anything is going to suggest a patient STOP preventative CF treatments on the hope that this drug will continue to be a long term fix. So even if it works, our CFers will still have a life (long I hope) filled with excessive appts. and hours of treatments. Maybe once they have 50 years of data they will be able to consider it a 'cure' but to be on the front end of it would seem difficult to believe that we can just throw away everything we are doing preventatively.
2. Considering the cost of drugs that are for a larger population than these mutation specific ones, the user cost is going to be very high for these. What if insurance decides not to cover it? Or if I can get it covered now but when my insurance changes or my daughter gets her own insurance she has to go without it?
So am I hopeful? Yes. Do I think that our kids will have a much better chance of living a longer, healthier life than kids diagnosed 40 years ago? Yes. But do I think CF is ever going away for them, do I think its really a 'cure'? No, I do not.
