Surufatinib, a kinase inhibitor targeting vascular endothelial growth factor receptors, fibroblast growth factor receptor 1 and colony stimulating factor-1 receptor, has demonstrated superior efficacy in extra-pancreatic neuroendocrine tumors (NETs) in a prior phase III study (ESMO 2019 Abs. LBA76). Here we report results from a parallel study of surufatinib in pancreatic NETs (pNETs).



The study evaluated the efficacy and safety of S in Pts with well-differentiated (pathological grade 1 or 2), progressive, unresectable or metastatic pNETs. Pts were randomized in a 2:1 ratio to receive S or P, 300 mg, orally, once daily, until disease progression or intolerable adverse events. Crossover at disease progression was allowed. The primary endpoint was investigator-assessed progression-free survival (PFS).



By the cutoff date on 11 November 2019 for the pre-planned interim analysis, 172 Pts were randomized, 113 pts to S and 59 to P. Baseline characteristics were well balanced. The study met the primary endpoint; investigator-assessed median PFS was 10.9 vs. 3.7 months in S and P arms, respectively, with hazard ratio (HR)=0.491; 95% confidence interval [CI]: 0.319–0.755; p=0.0011. Analysis by a blinded independent radiology committee confirmed PFS improvement (13.9 vs. 4.6 months; HR=0.339; 95% CI: 0.209–0.549; p<0.0001). The investigator-assessed objective response rate was 19.2% with S and 1.9% with P (p=0.0021). Most common (≥5% in either arm) grade ≥3 treatment-emergent adverse events (TEAEs) were hypertension (38.9% in S arm vs. 8.5% in P arm), proteinuria (9.7% vs. 1.7%), hypertriglyceridaemia (7.1% vs. 0), alanine aminotransferase increased and gamma-glutamyltransferase increased (both 2.7% vs. 5.1%). TEAEs leading to drug discontinuation occurred in 10.6% pts vs. 6.8% pts in S and P arm respectively.



Surufatinib significantly improved the PFS in Pts with progressive, well-differentiated advanced pNETs. The safety profile was manageable and consistent with observations in prior studies. Surufatinib represents a promising treatment option in the armamentarium against pNETs.
