Combination lenvatinib plus pembrolizumab treatment for recurrent endometrial cancer resulted in common adverse events, with no significant difference based on lenvatinib starting doses. Further optimization studies may be needed to guide dosing in clinical practice. Clinical trial data remains crucial for establishing standard dosing protocols.
Objective. To evaluate adverse events (AEs) of combination lenvatinib plus pembrolizumab for the treatment of recurrent endometrial cancer (EC) and to assess outcomes by lenvatinib starting dose.Methods. We retrospectively reviewed patients with recurrent EC treated with lenvatinib plus pembrolizumab at our institution between 10/1/2019-11/30/2021. Starting dose of lenvatinib was defined as standard (20 mg) or reduced (10 mg/14 mg). AEs were manually extracted through chart review and graded using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. PFS, overall survival (OS), and duration of response (DOR) were analyzed. Results. Forty-three patients were identified; median age was 67 years (range, 54-85). The most common histologies were serous (35%), endometrioid (23%), and carcinosarcoma (21 %). Starting lenvatinib doses were 10 mg (n = 10), 14 mg (n = 10), and 20 mg (n = 23). Median number of cycles received was 8 (range, 1-42). Twenty-four patients (56%) required >-1 lenvatinib dose reduction; 3 (7%) discontinued lenvatinib, and 1 (2%) discontinued pembrolizumab for intolerance or AE. Thirty-six patients (84%) experienced grade >-3 AEs; hypertension, weight loss, anemia, fatigue, and thrombocytopenia were most common. The standard dose group experienced significantly shorter observed PFS vs the reduced dose group (P = .02). There was no difference in DOR (P = .09) or OS (P = .27) between the groups.Conclusion. In clinical practice, AEs associated with combination lenvatinib plus pembrolizumab were common and comparable to Study 309/KEYNOTE-775 findings. AEs were similar regardless of starting lenvatinib dose. Further dose optimization studies of lenvatinib plus pembrolizumab may be indicated in recurrent EC. Clinical trial data remain the gold standard to guide starting lenvatinib dosing.(c) 2023 Elsevier Inc. All rights reserved.
