Safety and Efficacy of the Fully Humanized Anti - VEGF Monoclonal Antibody LYN00101

The purpose of this study is evaluate the pharmacokinetics, pharmacodynamics, immunogenicity and anti-tumor effect of of fully human anti - VEGF monoclonal antibody LY00101 and explore the potential prognostic and predictive biomarkers.

This study will not take into account the results of molecular-genetic tests of patients enrolled in the study

Tumors can be inactive for years, until transformation of cells into an angiogenic phenotype occurs. This phenomenon is known as angiogenic switch. It is based on balance between inhibitors and activators of angiogenesis.

Multiple genetic changes and processes leading to malignancies, such as activation of oncogenes, can trigger angiogenic switch.

Simple diffusion of nutrients and oxygen normally occurs within not more than 1-2 mm of tumor tissue. For further growth, blood supply and development of the vasculature are necessary.

Angiogenesis level in a tumor and it's metastasis activity has correlation with density of microvessels in a primary tumor and significantly affects disease prognosis.

Angiogenesis in a body is regulated through Vascular endothelial growth factor (VEGF) and its receptors.

There is a unique binding pattern of corresponding receptors typical for all members of the VEGF family:

* VEGF-A binds with VEGFR1 and VEGFR2
* VEGF-B and PlGF bind and activate receptor VEGFR1 only
* VEGF-C and VEGF-D communicate with receptor VEGFR3 (Flt4), triggering lymphangiogenesis, and demonstrate activity correlated with VEGFR2.

According to studies, VEGFR1 binds to the ligand with the highest affinity, binding VEGF and inhibiting VEGF-mediated signaling.

The VEGF-VEGFR2 binder induces autophosphorylation (and partial dimerization) of the catalytic domain of the PI3K / v-akt signaling pathway receptor (Phosphoinositide 3-kinase / murine thymoma viral oncogene homolog - Akt or serine / threonine protein kinase B, PKB), as well as Raf and MAP2K, which further phosphorylate MAPK (Erk).

Monoclonal antibody LYN00101 is not only a potent inhibitor of VEGF, also blocks autocrine growth factor loops by inhibiting VEGF and VEGFR 1/2/3 receptors and effectively blocking neoangiogenesis.

The purpose of this study is evaluate the pharmacokinetics, pharmacodynamics, immunogenicity and anti-tumor effect of of fully human anti - VEGF monoclonal antibody LY00101 and explore the potential prognostic and predictive biomarkers.

This study will not take into account the results of molecular-genetic tests of patients enrolled in the study.
