What was measured

PFS was defined as the time from date of study treatment to the first documented progressive disease (PD) based on RECIST 1.1, modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ or death due to any cause, whichever occurred first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of ≥5 mm. The appearance of one or more new lesions was also considered PD. The percentage of participants who experienced PFS per RECIST 1.1 by investigator assessment is presented. Per protocol, only data for Cohorts A and B were presented for this endpoint.

Analysis population: All allocated participants who received at least 1 dose of study intervention.

Groups in this outcome

Cohort A: Triple Negative Breast Cancer (Lenva + Pembro)

Participants received Pembrolizumab (pembro) 200 mg via intravenous (IV) infusion on Day 1 of each 21-day cycle (Q3W) for up to 35 cycles (up to 2 years) PLUS Lenvatinib (lenva) 20 mg via oral capsule once a day (QD) up to at least 2 years. Participants continued study intervention until progressive disease or unacceptable toxicity.

Cohort B: Ovarian Cancer (Lenva + Pembro)

Participants received Pembro 200 mg via IV infusion on Day 1 of each 21-day cycle (Q3W) for up to 35 cycles (up to 2 years) PLUS Lenva 20 mg via oral capsule QD up to at least 2 years. Participants continued study intervention until progressive disease or unacceptable toxicity.
