Lenvatinib and Pembrolizumab in People with Advanced Soft Tissue Sarcoma

Trial Status: Active

This phase II trial studies the effect of the combination of lenvatinib and pembrolizumab and how well it works in treating patients with soft tissue sarcomas that has spread to other places in the body (metastatic) and cannot be removed by surgery. Lenvatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving lenvatinib together with pembrolizumab together may kill more tumor cells.

PRIMARY OBJECTIVE:

I. To evaluate the efficacy of lenvatinib mesylate (lenvatinib) in combination with pembrolizumab in patients with select unresectable and/or metastatic soft tissue sarcomas as assessed by the best overall response rate (complete response + partial response) by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

SECONDARY OBJECTIVES:

I. To further assess the safety and tolerability of lenvatinib given in combination with pembrolizumab in patients with select soft tissue sarcomas.

II. To determine the progression free survival (PFS) rate at 27 weeks, median PFS and to determine overall survival (OS) for patients with select soft tissue sarcomas treated with lenvatinib given in combination with pembrolizumab.

III. To evaluate the efficacy of lenvatinib given in combination with pembrolizumab in patients with select soft tissue sarcomas as measured by immune-related RECIST criteria (irRECIST).

IV. To evaluate the duration of response by RECIST and irRECIST among the responders treated with lenvatinib given in combination with pembrolizumab.

EXPLORATORY OBJECTIVES:

I. To determine the baseline characteristics of sarcoma tumors (archival tissue) evaluated in this study including the level of PD-1/PD-L1 expression, gene expression profile, and T-cell receptor clonality in tumor-infiltrating lymphocytes (TIL).

II. To evaluate the association between selected immune-related biomarkers measured in serial peripheral blood and with clinical efficacy, including immunophenotyping and functional analyses, evaluation of serum levels of chemokines, cytokines and other immune mediators, and characterization of T-cell receptor clonality in peripheral blood.

III. To assess the potential effect of lenvatinib and pembrolizumab on selected biomarker expression measured in pre- and post-treatment tumor tissue and the association between these biomarkers and with clinical outcome, including characterization of PD-1/PD-L1 expression, tumor infiltrating lymphocytes (TILs) and tumor antigens, gene expression profiling (germline and somatic), and characterization of T-cell receptor clonality in tumor-infiltrating lymphocytes (TIL).

IV. To evaluate the association between baseline tumor mutational burden and neoantigen production with clinical efficacy of the study therapy.

V. To evaluate the association between angiogenesis markers including microvessel density, expression of various receptors (e.g. vascular endothelial factor growth receptor [VEFGR] 1-3, fibroblast growth factor receptor [FGFR] 1-3, platelet-derived growth factor [PDGF]-alpha/beta), and expression of hypoxia inducible factor (HIF)-1alpha in tumor and circulating cytokine/angiogenic factors (CAFs) in blood samples collected at baseline and on treatment with clinical efficacy and immune related markers.

OUTLINE:

RUN-IN PERIOD: Patients receive lenvatinib orally (PO) once daily (QD) on days 1-14.

TREATMENT PERIOD: Patients receive lenvatinib PO QD on days 1-21 and pembrolizumab intravenously (IV) over 25-40 minutes on day 1. Treatment repeats every 21 days for up to 35 cycles of pembrolizumab or achieving confirmed complete response (CR) in the absence of disease progression or unacceptable toxicity. Patients who progress after having discontinued therapy after completing 2 years of treatment or after achieving confirmed CR may reinitiate to receive lenvatinib PO QD and pembrolizumab IV for an additional 1 year (17 cycles).

After completion of study treatment, patients are followed up for 30 days.
