If the study drug becomes commercially available while you are on study, you may begin to receive it off of this study. It is also possible that you will continue to receive the study drug as part of an extension study, or from a government-sponsored or private health program. It is also possible that you and/or your insurance provider will have to pay for drugs after they become commercially available if you and your doctor wish to continue them. The study doctor will tell you more if any of these things happen.
