| Phase 2 |
Detailed Description
AZD2014 50mg BD continuous schedule of a 28 day cycle AZD2014 will be administered with orange juice in STG/TG patients. AZD2014 can be taken with or without food. The first dose of the day should be taken at approximately the same time each morning.The second dose of the day should be taken approximately 12 hours after the morning dose.
