Abstract Purpose: Standard treatment for patients with unresectable locally advanced or metastatic soft-tissue sarcoma (LA/M STS) is chemotherapy based on anthracyclines, but patient tolerance of chemotherapy is limited. The present trial (NCT03792542) investigated the use of anlotinib as first-line treatment for patients with advanced STS, in particular liposarcoma. Patients and Methods: Eligible patients were previously untreated, pathologically confirmed, unresectable LA/M STS cases. Anlotinib was given orally at a dose of 12 mg once daily from days 1 to 14 every 3 weeks until disease progression or intolerable adverse events (AE) occurred. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were overall survival (OS), objective response rate, and disease control rate (DCR). The safety profile was also evaluated. Results: Forty patients were enrolled from April 2019 to June 2022 and are included in the intention-to-treat analysis. The median PFS was 6.83 months 95% confidence interval (CI), 4.17–8.71 and the median OS 27.40 months (95% CI, 16.43–not evaluable); 1 patient reached partial response and 26 attained stable disease, with a DCR of 67.5% (27/40). Median PFS and OS times for liposarcoma patients were 8.71 and 16.23 months, respectively. Ten (25.0%) patients had treatment-related AEs ≥ grade 3, with in particular a higher incidence of hypertension (15.0%) and proteinuria (7.5%). Conclusions: The findings suggest a potential benefit in using front-line anlotinib to treat patients with STS, who are not eligible for cytotoxic chemotherapy. Of note, the clinical outcomes for the liposarcoma subgroup of patients were encouraging. See related commentary by Napolitano et al., p. 4257
