What was measured

For participants who demonstrate a confirmed complete response (CR: Disappearance of all target lesions) or confirmed partial response (PR: At least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until disease progression or death. The DOR as assessed by blinded independent central review is presented here. The Median DOR was analyzed by the Kaplan-Meier method for censored data.

Analysis population: Per protocol, the analysis population consisted of all randomized participants based on the treatment group to which they were randomized, and who experienced a confirmed complete response (CR) or partial response (PR). Per protocol, participants enrolled in the Safety Run-In were not randomized and not included in the protocol-specified analyses for any of the outcome measures.

Groups in this outcome

Belzutifan

Randomized participants received 120 mg of belzutifan orally once daily (QD), until disease progression or discontinuation.

Everolimus

Randomized participants received 10 mg of Everolimus orally QD, until disease progression or discontinuation.
