The primary objective is satisfaction with overall CS symptom control 6 months after starting XERMELO. Secondary objectives will evaluate satisfaction with control of CSD and flushing, CS symptoms, work productivity and activity impairment, SSA use, and weight. This study will provide real-world patient-reported outcomes in CS with XERMELO treatment for at least 6 months.
