Trial Outcomes & Findings for SARC016: Study of Everolimus With Bevacizumab to Treat Refractory Malignant Peripheral Nerve Sheath Tumors (NCT NCT01661283)

NCT ID: NCT01661283

Last Updated: 2019-03-06

Results Overview

Evaluate if the combination of the mTOR inhibitor everolimus combined with the angiogenesis inhibitor bevacizumab would result in a modest clinical benefit rate, which included confirmed partial and complete responses and disease stability for four or more treatment cycles based on WHO Response Criteria. Per WHO for target lesions: Complete Response (CR): Disappearance of all known disease, determined by two consecutive observations not less than 4 weeks apart. Partial Response (PR): A \> 50% decrease in the total tumor load of the lesions that have been measured to determine the effect of therapy not less than four weeks apart. The observations must be consecutive. Stable Disease (SD): A 50% decrease in total tumor area cannot be established nor has a 25% increase in the size of one or more measurable lesions been demonstrated.
