What was measured

ORR was defined as the percentage of participants who had a best overall response of either Complete Response (CR): Disappearance of all target lesions or Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions as assessed by RECIST 1.1. The percentage of participants who experienced a CR or PR as assessed by RECIST 1.1 by investigator assessment was 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.
