PURPOSE To evaluate the effect of the anti-VEGF-A monoclonal antibody bevacizumab on primary human Tenon's capsule fibroblasts (HTFs) in an in vitro model of wound healing. METHODS Fibroblasts were cultured in RPMI media, and bevacizumab was administered at a concentration ranging from 0.25 to 12.5 mg/mL. Fibroblast viability and cell death were assessed using the MTT colorimetric assay, lact...

BACKGROUND Retinal endothelial cells are crucially involved in the genesis of diabetic retinopathy which is treated with vascular endothelial growth factor (VEGF) inhibitors. Of these, ranibizumab can completely restore VEGF-induced effects on immortalised bovine retinal endothelial cells (iBREC). In most experiments supporting diabetic retinopathy therapy with bevacizumab, only non-retinal EC ...

PURPOSE Vascular endothelial growth factor (VEGF) promotes acute myelogenous leukemia (AML) cell growth and survival and may contribute to drug resistance. bevacizumab, an anti-VEGF monoclonal antibody, exhibits clinical activity against diverse malignancies when administered with cytotoxic chemotherapy. We conducted a Phase II clinical trial of bevacizumab administered after chemotherapy to ad...

BACKGROUND The monoclonal antibody bevacizumab effectively inhibits angiogenesis in several types of cancers by blocking vascular endothelial growth factor. However, life-threatening cardiovascular adverse effects could limit its use and may warrant specific follow-up strategies. METHODS AND RESULTS We systematically searched MEDLINE, Cochrane, EMBASE, and Web of Science for randomized contro...

purpose: to compare the results of intravitreal bevacizumb (ivb) injection alone or in combination with intravitreal triamcinolone acetonide (ivt) versus macular laser photocoagulation (mpc) as primary treatment of diabetic macular edema (dme). methods: in this randomized clinical trial, 150 eyes of 129 patients with clinical dme and no previous treatment were enrolled. the eyes were randomly a...

AIM To investigate the safety and efficacy of adding bevacizumab to first-line chemotherapy in metastatic colorectal cancer patients with peritoneal disease. METHODS We compared rates of gastrointestinal perforation in patients with metastatic colorectal cancer and peritoneal disease receiving first-line chemotherapy with and without bevacizumab in three distinct cohorts: (1) the AGITG MAX tr...

Colorectal cancer is one of the most common cancers worldwide. The prognosis of patients with metastatic colorectal cancer in recent years has increased from 5 months with best supportive care to nearly 2 years with chemotherapy combined with bevacizumab, an antivascular endothelial growth factor monoclonal antibody. New prognostic and predictive biomarkers have been identified to guide chemoth...

AIM To investigate whether single-dose intravitreal injections of bevacizumab and ranibizumab transfer into milk. METHODS This study included lactating 12 sheep and a single 3-month old suckling lamb of each sheep. Two groups consisting of 6 sheep and their lambs were constituted; the ranibizumab group and the bevacizumab group before the administration of intravitreal injections, blood and m...

PURPOSE To evaluate the efficacy of bevacizumab as an antifibrotic agent after trabeculectomy in rabbits. METHODS Forty-two rabbits underwent trabeculectomy and were randomly assigned to receive a postoperative course of seven subconjunctival injections of bevacizumab (1.25 mg, 25 mg/mL), 5-fluorouracil (5-FU; 5 mg, 50 mg/mL), or balanced salt solution (BSS; 0.1 mL, control). Bleb survival an...

Human tumors are dependent on angiogenesis for growth, and the vascular endothelial growth factor (VEGF) is a major regulator of this process. Bevacizumab (Avastin), a monoclonal antibody directed against VEGF, has shown promise in treating a variety of cancers. In this study, we first examined the anti-tumor effects of bevacizumab on head and neck squamous cell carcinoma (HNSCC). Then we exami...
