Blood samples were collected from the tail vein into heparinized tubes prior to administration and at 2, 4, 8, 12, 24, 72, 96,and h after drug administration. Endostatin shows a broad anti-cancer spectrum and a low toxicity in animal models The radioactivity concentrations of I-M 2 ES in the TCA precipitants were lower than those in the total radioactivity concentrations in both the plasma and other tissues, but they followed approximately the same trend. Radiographic assessments were conducted to determine tumor response according to the Response Evaluation Criteria in Solid Tumor 18 Endostatin: yeast production, mutants, and antitumor effect in renal cell carcinoma. Eight patients presented with locally advanced stage III and 8 patients had metastatic stage IV disease. Phase I clinical trial of recombinant human endostatin administered as a short intravenous infusion repeated daily. M 2 ES was administered at escalating doses intravenously 1 h after gemcitabine administration on days 1, 8, 15 and

    Pre-clinical study of PEGylated recombinant human endostatin (M2ES) was were observed in 15 and 75 mg/kg M2ES groups, but this adverse-effect was. Dr. Luo Says He Has Improved Dr. Folkman's Endostatin, But U.S.

    Trials Yet to Start Luo Yongzhang was among the many who were disappointed. and one of the two who switched to Avastin is suffering from side effects.
    Exp Cell Res ; : — China, E-mail: moc.

    Furthermore, this PEGylated endostatin did not exhibit increased toxicity when compared to the original recombinant endostatin 28 The concentrations of I-labeled M 2 ES were determined by using the bicinchoninic acid assay according to the instructions of the manufacturer.

    The calibration curves were generated by adding a series of concentrations of I-labeled M 2 ES 0. The toxicities and adverse events of this protocol were graded according to the National Cancer Institute Common Toxicity Criteria, version 3.

    Introduction Endostatin, a kDa proteolytic fragment of collagen XVIII, is a potent endogenous angiogenesis inhibitor isolated from supernatant of a murine hemangioendothelioma cell line 1. M 2 ES and I-labeled M 2 ES from 33rd and 31st eluted fractions at indicated concentrations were added in the lower chamber.

    However, the total plasma radioactivity was significantly higher than the TCA precipitant radioactivity at and h following drug injection, indicating that small molecules of radiolabeled degradation products from parent drugs existed in the supernatants after h. Antiangiogenesis in cancer therapy - endostatin and its mechanisms of action.

    and YONGZHANG LUO Endostatin is a potent endogenous inhibitor of angiogenesis, which may be administered in The most noticeable M2ES-​related adverse events observed during the trial were grade 2 liver function.

    and Yong-zhang Luo M2ES is PEGylated recombinant human endostatin. Except in endothelial cells, endostatin also has anti-tumor . adjusting the dosage is needed to avoid adverse effects in patients whose kidney.

    Yongzhang Luo To overcome these shortcomings, PEGylated recombinant human endostatin was developed. there was no observable serious adverse event in both acute toxicity and safety pharmacology study.

    The bile was collected at an intervals of 1 h over 12 h, and the volume of each collected sample was recorded separately. Briefly, 5. A phase I study of erlotinib in combination with gemcitabine and radiation in locally advanced, non-operable pancreatic adenocarcinoma.

    Of the 15 evaluable patients, 6 patients achieved SD with therapy.

    The tissue distribution and excretion pattern of M 2 ES in rats were also investigated.

    The N-terminal modified recombinant human endostatin has been one of the most widely-used anti-angiogenic drugs in the clinics for seven years in China. Recent studies on erlotinib, an epidermal growth factor receptor inhibitor, plus gemcitabine, provided the foundation for approval of such regimens for the treatment of advanced pancreatic adenocarcinoma 24 and reported a SDR of 53— Keywords: polyethylene glycosylated endostatin, pancreatic cancer, gemcitabine, phase I.

    Erlotinib plus gemcitabine compared with gemcitabine alone in patients with advanced pancreatic cancer: a phase III trial of the National Cancer Institute of Canada Clinical Trials Group.

    After trials of the angiogenesis inhibitor endostatin ended, Judah “If a patient's tumor regresses 10% a year, or remains stable with no side effects, this is including one of the original investors in EntreMed, Luo Yongzhang.

    Corresponding author: Yongzhang Luo, [email protected] Endostatin is a well-known angiogenesis inhibitor. for treating some types of obesity, poor long-term adherence rates, and serious adverse effects (12). Shan Wang, Xin-an Lu, Peng Liu, Yan Fu, Lin Jia, Shunli Zhan and Yongzhang Luo Endostatin is an endogenous angiogenesis inhibitor with . in space with all of their side chains stretching inside the molecule, therefore.

    Journal List Acta Pharmacol Sin v. In conclusion, to the best of our knowledge, this study was the first clinical trial of a PEGylated recombinant human endostatin, M 2 ES, in advanced pancreatic cancer patients. Therefore, I-M 2 ES was found to have a similar biological activity as unlabeled M 2 ES, and no significant difference was observed, indicating that I-labeling did not influence the activity of M 2 ES.

    Systematic administration of rh-endostatin suppressed the growth of a number of primary tumors in mice, including Lewis lung carcinoma, T fibrosarcoma, B16F10 melanoma 12 and renal cell carcinoma 13without the development of resistance or apparent toxicity.

    Endostatin potently constrains the proliferation and migration of endothelial cells, therefore hindering tumor angiogenesis and tumor growth 34.

    The corresponding pharmacokinetic parameters were generated by fitting plasma radioactivity concentration profiles to a non-compartmental model as shown in Table 1.

    Phase I clinical trial of recombinant human endostatin administered as a short intravenous infusion repeated daily. Figure 3.

    The radioactivity distribution and AUC values in different tissues at indicated time points were analyzed. The fractions containing I-labeled M 2 ES were combined.
