Radiologically documented progression of any existing tumor (growth > 15% of the bidimensional enhancing tumor within the prior 6 months or appearance of new lesions (including intra and extracranial manifestations).
For participants treated with external beam radiation, interstitial brachytherapy, or radiosurgery, an interval ≥ 24 weeks must have elapsed from completion of therapy to initiation of treatment.
