• Research summary

  Vertex Pharmaceuticals Incorporated, is developing a drug called VX-770 as a possible treatment for Cystic Fibrosis (CF). VX-770 is an experimental drug, which means that it has not been approved for prescribing to people. VX-770 is being studied to see if it can help decrease some of the effects caused by CF. This study is also being done to learn more about the safety and effects of VX-770 on CF patients. This is a randomized, double-blind and placebo-controlled study being done at up to 80 CF centers in North America, Europe and Australia. Randomized means that the choice of whether the patient will be given VX-770 or a pill that looks just like VX-770, but does not contain any medicine ( a placebo), will be assigned by a computer, by chance, like the flip of a coin. They will have a 50:50 chance of receiving VX-770. No one can choose what anyone receives. Double-Blind means that no one at the study site will know if the patient is taking VX-770 or the pill that does not contain any medication. The doctor can find out what medication the patient is on if it is necessary for your medical care. Placebo controlled means that a pill that looks just like the VX-770 pill but does not contain VX-770 or any other medicine (a placebo) will be taken by some people in this study. This is done so that the study findings can be looked at fairly.At least 80 subjects will take part in this study. This study will check the safety and effect of taking 150 mg of VX-770 by mouth twice a day for 48 weeks. Participation in this study will last up to 3 years.
