Hey Lance,
Let me share what I sent to my friends and then add a few comments, fwtw:
Wanted to share the good news and thank you all for your prayers over the last 6 years: On Thursday, the FDA approved Orkambi for those 12 and older. This drug corrects the underlying defect for those that have [son's] mutation--two copies of ddf508. They are finishing the trial for those 6-11 with results in October and hopefully approval early next year and then [son] can start taking (if I can get him to swallow a pill!). While not a cure...it will be a help. Currently, [son's] CFTR gene functions about 1%...yours 100%, mine 80/90%. This med gets it to 25% function. Those who have less severe CF mutations and have CFTR function of about 30% have "mild" cases, so we are hopeful this will help him stay healthy longer while they continue. The next generation of drugs will be in clinic by end of year for trials and then next year to combine with this drug and in vitro shows it gets the function to around 50%-60%. That will likely be another 5 years out, but this first step was 5 years away when [son] was diagnosis...and it goes fast! And they are also working on gene modifications...hopefully by the time he's ready for college they'll have his bad gene sliced out and a good one inserted and with the other meds in the meantime, hopefully his lungs won't be permenantly damaged.
Thank you all for your support and friendship.
so no, it's not a cure. no, it won't mean you don't have to stop your other medicines, but it slows the progression of the disease and improves lung function and for those with weight troubles, it helps them gain weight and probably most significantly, it reduces excerbations by something like 40% (don't have the info handy). This is just the first step and gives more time for folks to stay healthier while we wait for "the cure." Those who benefit from Kalydeco have seen in some cases supposed permenant damage reverse (they're learning it wasn't permenant!), and some have had normal sweat tests and able to stop many treatments. Without lung damage, some with ddf508 will be there too when another corrector is added. Hope this helps and that it works well for you.
