What was measured

PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by blinded independent central review is presented here.

Analysis population: Per protocol, the analysis population consisted of all randomized participants based on the treatment group to which they were randomized. 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.
