CFTR modulation for those with ONE copy of DDF508?

Does anyone have info on cftr modulation drugs for people that carry only one copy of the DDF508 mutation, and another of..something else? My other mutation is a nonsense mutation. Are any clinical trials going on for those of us in this boat? Or is there any research on Kalydeco combined with other drugs for the patients with one ddf508? Thanks!
