Exclusion Criteria

• Any planned radiation to the pelvis; or cranial radiation ≥ 30 gray (Gy) to the hypothalamus, inclusive of any total body irradiation (TBI).

Note: Please see protocol for the concomitant therapy restrictions for patients during the study treatment period. See protocol for information about oral and other hormonal contractive use during the study treatment period.

• Any prior radiation to the pelvis; or cranial radiation ≥ 30 Gy to the hypothalamus, inclusive of any total body irradiation (TBI).
