Spots Global Cancer Trial Database for Trial of Lenvatinib Plus PembrolizumAb in Recurrent Gynecological Clear Cell Adenocarcinomas (LARA)

Study Description

Brief Summary: This is a phase II non-randomized, multi-center study. The primary end point of this study is the objective response rate (ORR) at 24 weeks, using response evaluation criteria for solid tumors (RECIST) 1.1 criteria, for the combination therapy of continuous daily oral lenvatinib with three-weekly intravenous pembrolizumab in patients with recurrent clear cell carcinoma of gynecological origin (CCGC). The statistical design is Simon's minimax two-stage design and the present study aims to complete stage 1 of the Simon's two-stage design.

Detailed Description: Primary Objective (1) Objective: To determine the efficacy as measured by the objective response rate (ORR) at 24 weeks using RECIST 1.1 criteria when patients with recurrent CCGCs are treated with lenvatinib plus pembrolizumab. Hypothesis: The ORR (complete response plus partial response) at 24 weeks seen in recurrent CCGC patients treated with lenvatinib plus pembrolizumab combination therapy will be improved compared to historical control (hypothesized ORR of 30% with combination therapy compared to historical ORR of ORR of 10% with chemotherapy). Primary Endpoint: The ORR at 24 weeks using RECIST 1.1 criteria when patients with recurrent CCGCs are treated with lenvatinib plus pembrolizumab. Secondary Objectives, 1. Objective: To determine the efficacy of lenvatinib plus pembrolizumab in recurrent CCGCs. Hypothesis: The ORR by immune RECIST (iRECIST) criteria, progression-free survival (PFS) rate and clinical benefit rate (CBR) (complete response plus partial response plus stable disease) at 24 weeks, as well as duration of response and PFS observed in recurrent CCGC patients treated with lenvatinib plus pembrolizumab combination therapy will be improved compared to historical control. Endpoint: To determine the ORR using iRECIST criteria at 24 weeks when patients with recurrent CCGCs are treated with lenvatinib plus pembrolizumab. Endpoint: To assess the duration of response when patients with recurrent CCGCs are treated with lenvatinib plus pembrolizumab. Endpoint: To assess the PFS when patients with recurrent CCGCs are treated with lenvatinib plus pembrolizumab. Endpoint: To determine the 24 week PFS rate of lenvatinib plus pembrolizumab in this population. Endpoint: To determine the CBR at 24 weeks of lenvatinib plus pembrolizumab in this population. 2. Objective: To describe the adverse event (AE) profile of lenvatinib plus pembrolizumab in this patient population. Exploratory Objectives 1. Clinical Objectives: To evaluate the effect of potential prognostic factors (baseline patient and tumor characteristics, notably: initial performance status, stage at diagnosis and platinum-free interval), on the efficacy of lenvatinib plus pembrolizumab in this population. 2. Translational Objectives: To evaluate the pre- to post-treatment changes in the frequency of tumor-associated macrophages (TAMs) in patients receiving lenvatinib plus pembrolizumab. 3. Translational Objectives: To evaluate the pre- to post-treatment changes in the frequency and gene expression profile of different lymphocyte (e.g. CD4, CD8, Treg, B cells) and myeloid (e.g. DCs, MDSCs) subsets in patients receiving lenvatinib plus pembrolizumab. 4. Translational Objectives: To identify predictive biomarkers of response in patients receiving lenvatinib plus pembrolizumab (e.g. PD-1/PD-L1/VEGF expression). 5. Translational Objectives: To evaluate the pre-to post-treatment changes in the concentration of relevant cytokines/chemokines (e.g.: GM-CSF, G-CSF, VEGFA, IL2, IL12, IL13, IL6, Interferons) in patients receiving lenvatinib plus pembrolizumab.
