BACKGROUND/AIMHepatocyte growth factor (HGF) acts as a key regulator in promoting ovarian cancer metastasis. Previously, we observed that YYB-101, a humanized anti-HGF antibody, effectively inhibits ovarian cancer cell migration, invasion, and progression. Here, we evaluated the signaling mechanisms affected by YYB-101 that are important in ovarian cancer cell progression.MATERIALS AND METHODSUsing cell migration, invasion and proliferation assays, we evaluated the effects of YYB-101 on A2780/luc and SKOV3 cells. The effects of YYB-101 on signaling molecules were determined by immunocytochemistry and immunoblot analysis.RESULTSYYB-101 inhibited HGF-induced ovarian cancer cell motility by down-regulating paxillin phosphorylation and actin-cytoskeleton rearrangement. Also, YYB-101 inhibited ovarian cancer cell proliferation by reducing c-MET phosphorylation and activating apoptosis in vitro and in vivo. These effects were significantly enhanced by combining YYB-101 treatment with paclitaxel, a standard chemotherapy drug.CONCLUSIONYYB-101 can be examined as a new therapeutic agent for the treatment of patients with ovarian cancer.

Background: YYB101, a humanized monoclonal antibody against hepatocyte growth factor (HGF), has shown safety and efficacy in vitro and in vivo. This is a first-in-human trial of this antibody. Materials and Methods: YYB101 was administered intravenously to refractory cancer patients once every 4 weeks for 1 month, and then once every 2 weeks until disease progression or intolerable toxicity, at doses of 0.3, 1, 3, 5, 10, 20, 30 mg/kg, according to a 3+3 dose escalation design. Maximum tolerated dose, safety, pharmacokinetics, and pharmacodynamics were studied. HGF, MET, PD-L1, and ERK expression was evaluated for 9 of 17 patients of the expansion cohort (20 mg/kg). Results: In 39 patients enrolled, no dose-limiting toxicity was observed at 0.3 mg/kg, and the most commonly detected toxicity was generalized edema ( n = 7, 18.9%) followed by pruritis and nausea ( n = 5, 13.5%, each), fatigue, anemia, and decreased appetite ( n = 4, 10.8%, each). No patient discontinued treatment because of adverse events. YYB101 showed dose-proportional pharmacokinetics up to 30 mg/kg. Partial response in 1 (2.5%) and stable disease in 17 (43.5%) were observed. HGF, MET, PD-L1, and ERK proteins were not significant predictors for treatment response. However, serum HGF level was significantly lowered in responders upon drug administration. RNA sequencing revealed a mesenchymal signature in two long-term responders. Conclusion: YYB101 showed favorable safety and efficacy in patients with refractory solid tumors. Based on this phase I trial, a phase II study on the YYB101 + irinotecan combination in refractory metastatic colorectal cancer patients is planned. Conclusion: ClinicalTrials.gov Identifier: NCT02499224

BACKGROUNDCancer is a complex disease with profound genomic alterations and extensive heterogeneity. Recent studies on large-scale genomics have shed light on the impact of core oncogenic pathways, which are frequently dysregulated in a wide spectrum of cancer types. Aberrant activation of the hepatocyte growth factor (HGF) signaling axis has been associated with promoting various oncogenic programs during tumor initiation, progression, and treatment resistance. As a result, HGF-targeted therapy has emerged as an attractive therapeutic approach. However, recent clinical trials involving HGF-targeted therapies have demonstrated rather disappointing results. Thus, an alternative, in-depth assessment of new patient stratification is necessary to shift the current clinical course.METHODSTo address such challenges, we have evaluated the therapeutic efficacy of YYB-101, an HGF-neutralizing antibody, in a series of primary glioblastoma stem cells (GSCs) both in vitro and in vivo. Furthermore, we performed genome and transcriptome analysis to determine genetic and molecular traits that exhibit therapeutic susceptibility to HGF-mediated therapy.RESULTSWe have identified several differentially expressed genes, including MET, KDR, and SOX3, which are associated with tumor invasiveness, malignancy, and unfavorable prognosis in glioblastoma patients. We also demonstrated the HGF-MET signaling axis as a key molecular determinant in GSC invasion, and we discovered that a significant association in HGF expression existed between mesenchymal phenotype and immune cell recruitment.CONCLUSIONSUpregulation of MET and mesenchymal cellular state are essential in generating HGF-mediated therapeutic responses. Our results provide an important framework for evaluating HGF-targeted therapy in future clinical settings.
