* Disease control rate was a post hoc exploratory endpoint and was not prespecified. Therefore it should be interpreted with caution.1,3
AMPECT=Advanced Malignant PEComa Trial; CR=complete response; DOR=duration of response; PD=progressive disease; PEComa=perivascular epithelioid cell tumor; PR=partial response; RECIST=Response Evaluation Criteria in Solid Tumors; SD=stable disease.
*Target tumor reduction may not match Best Overall Response Assessment, which also takes into consideration nontarget lesions and the observations of new lesions as per RECIST v1.1. SD and PD could be due to the natural course of the disease and not due to treatment.5
†One patient had an unconfirmed PR and thus best response is SD as per RECIST v1.1 (confirmation of response requirement).3,4
‡One patient with overall CR had a measurable lymph node as target tumor, but <10 mm.3
§Two patients with CRs of target tumor reduction had PRs as best response because of unresolved nontarget lesions.1
