Abstract
Purpose: Survival of patients with metastatic sarcoma remains poor, and there is pressing need for new therapies. Most sarcoma subtypes are not responsive to immune checkpoint inhibition alone. Lenvatinib, a multi-receptor tyrosine kinase inhibitor targeting tumor vasculature, has immunomodulatory activity that contributes to its antitumor effects. Therefore we hypothesized that combination of lenvatinib and pembrolizumab would lead to improved clinical outcomes in patients with sarcoma. Methods: This was an open-label, single-arm study of lenvatinib and pembrolizumab in the following cohorts A: leiomyosarcoma, B: undifferentiated pleomorphic sarcoma (UPS), C: vascular sarcomas (angiosarcoma and epithelioid hemangioendothelioma), D: synovial sarcoma or malignant peripheral nerve sheath tumor (MPNST), and E: bone sarcomas (osteosarcoma and chondrosarcoma). The primary endpoint was best overall response (BOR) rate documented by RECIST v1.1 by 27 weeks in each cohort, with a threshold of ≥2 responses among 10 patients. Secondary endpoints included progression-free survival, overall survival, duration of response and safety. Results: Forty-six patients were evaluable for the primary endpoint which was met in the UPS and MPNST/synovial cohorts (BOR rates by 27 weeks of 25% and 30%,respectively). There were 7 partial responses overall with additional responses noted in angiosarcoma and osteosarcoma. Treatment-related adverse events of any grade, and Grade 3 or higher, occurred in 50/51 (98%) and 29/51 (57%) of patients respectively. Conclusions: We observed durable responses in MPNST, synovial sarcoma and osteosarcoma. Patients with UPS and angiosarcoma also responded. Further exploration of this approach is warranted to confirm activity and determine optimal dosing schedules.
期刊介绍:
Clinical Cancer Research is a journal focusing on groundbreaking research in cancer, specifically in the areas where the laboratory and the clinic intersect. Our primary interest lies in clinical trials that investigate novel treatments, accompanied by research on pharmacology, molecular alterations, and biomarkers that can predict response or resistance to these treatments. Furthermore, we prioritize laboratory and animal studies that explore new drugs and targeted agents with the potential to advance to clinical trials. We also encourage research on targetable mechanisms of cancer development, progression, and metastasis.
