Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Non-functioning Pituitary Adenomas (NFPA) Who Achieve Tumor Volume Reduction of at Least 20% After 24 Weeks (FAS)Baseline up to 24 weeks

Tumor volume was evaluated by MRI. MRIs were performed and processed according to the guidelines of the central evaluator's facility.The pituitary adenomas were measured by a neuro-radiologist, using manual tracing together with the imaging analysis software. The largest diameter at any plan determined the maximum diameter of the tumor. A change ≥ 20% in the original volume of the tumor was considered to be clinically significant. Evaluable participants required tumor volume assessment at baseline and at week 24.
