OBJECTIVE: KEYNOTE-775 defined lenvatinib/pembrolizumab as the new standard-of-care for patients with proficient mismatch repair (pMMR) recurrent EC. However, the regimen required dose reductions in 66.5 % of participants and the generalizability of these results was uncertain. We conducted an observational study to determine the prescribing patterns, outcomes and side effects in a real-world setting.
METHODS: A national multidisciplinary consortium was utilized to study treatment patterns of patients with advanced/recurrent EC treated with lenvatinib/pembrolizumab from 2019 through 2022. Treatment decisions were based on the physician's recommendation.
RESULTS: 188 patients across 14 institutions were included. Histologic subtypes were 33 % endometrioid, 41 % serous, 9.6 % mixed, 10.1 % carcinosarcoma, and 2.1 % clear cell. 85.6 % were pMMR and 5.3 % were dMMR. Lenvatinib starting dose was 20 mg in 19.7 %, 18 mg in 14.9 %, 14 mg in 47.3 %, and 10 mg in 18.1 %. Median dose intensity of lenvatinib was 14 mg. Pembrolizumab dosing was 200 mg Q3W in 94.1 %. Grade ≥ 3 adverse events (AE) rates related to lenvatinib were similar across starting doses: 20 mg (13.5 %), 18 mg (17.9 %), 14 mg (7.9 %), 10 mg (17.6 %) (p = 0.31). Response rates in relation to lenvatinib starting dose were 20 mg (27 %), 18 mg (35.7 %), 14 mg (39.3 %), 10 mg (44.1 %) (p = 0.50). In relation to lenvatinib starting dose, PFS, OS and duration of therapy were not statistically different. Response rates (p = 0.24), PFS (p = 0.66) & OS (p = 0.22) were similar in White and Black patients.
CONCLUSIONS: In a real-world analysis, the predominant starting dose was 14 mg lenvatinib and 200 mg pembrolizumab. Starting at varying doses does not appear to compromise response rates or survival and no new severe adverse events emerged.
