Hello,
I, too, am interested in Ataluren/PTC 124 as my 1.5 year old boy has a nonsense mutation (R1162X). I checked out the PTC website and the clinical trials website; I learned that the Phase 3 Ataluren trial is still underway with an expected completion date of March 2012. I hope for the best.
[On a side note: I'm glad to see that we can openly discuss drugs in the pipeline on this forum. Right after my son was born, I posted an article about the encouraging signs of Vertex' trials/tests. One of the moderators sent me a message, accused me of being an employee of a drug company and I was banned from this website. I've created a new username as I really like this site and hope to contribute. Hopefully, I won't be banned again. I'll say in no uncertain terms: I have NO connection to any drug company. Thanks.]
