Abstract

Abstract: : The benefit of systemic treatment in esophageal squamous cell carcinoma (ESCC) which has progressed after chemotherapy is still uncertain. Anlotinib (AL3818) is a novel multi-target TKI, inhibiting tumor angiogenesis and proliferation. A phase II trial (NCT02649361) has demonstrated that anlotinib has a durable antitumor activity with a manageable adverse event profile in refractory metastatic ESCC. This study (NCT03387904) aimed at comparing the effects and safety of Anlotinib Plus Irinotecan versus Irinotecan in patients with ESCC. Methods: We conducted a prospective randomized, multicenter, phase II trial to compare the efficacy of Anlotinib Plus Irinotecan with Irinotecan in recurrent ESCC patients who had resistance to platinum or taxane-based chemotherapy. Eligible patients were adults with pathologically confirmed recurrent ESCC, and 82 patients were randomized 1:1 to Irinotecan (65 mg/m 2 /day 1 and day 8) with or without anlotinib (12 mg qd day 1 to 14) of a 21-day cycle till progression or intolerable. The primary endpoint is the disease control rate (DCR) and progression-free survival (PFS) and the secondary end points are objective response rate (ORR) and overall survival (OS). Results: Between 13/1 2019 and 20/1 2020, a total of 43 patients were enrolled and randomly assigned to either the anlotinib plus irinotecan (n = 22) or the irinotecan group (n = 21).The mPFS was longer in trial group than in control group (89 days vs 66 days, HR = 0.447, P = 0.055). The Disease control rate (DCR) was 54.5% in trial group and 38.1% in the control group. The treatment-related adverse events (>10%) were fatigue (59.1%), nausea (50.0%), decreased appetite (36.4%), hoarseness (27.3%), thyroid-stimulating hormone elevation (22.7%), diarrhea (9.1%), and decreased lymphocytes count(9.1%) in trial group. Grade 3 AEs included fatigue (4.5% vs 4.8%), nausea (4.5% vs 0%) and diarrhea (4.5% vs 0%) in two groups. Conclusion: Anlotinib plus irinotecan was similarly tolerable but prolonged PFS compared to irinotecan monotherapy as a second-line treatment in patients with recurrent ESCC.
