    • PROBLEM TO BE SOLVED: To provide anti-VEGF (vascular endothelial growth factor) antibody for blocking or preventing relapse tumor growth or relapse cancer cell growth, and for treating non-neoplastic conditions comprising chronic inflammation or atherosclerosis, and to provide its composition.SOLUTION: A VEGF antibody comprises HVR antibodies selected from six HVRs as follows: (i) an HVR-L1 comprising the amino acid sequence of X1X2R X3SL [X1 is G or A, X2 is V or I, and/or X3 is T or R], wherein the HVR-L1 comprises 1, 2 or 3 substitutions in any combination of the following positions; (ii) an HVR-L2 comprising the amino acid sequence of DASSLA; (iii) an HVR-L3 comprising the amino acid sequence of SYKSPL; (iv) an HVR-H1 comprising the amino acid sequence of SISGSWIF; (v) an HVR-H2 comprising the amino acid sequence of GAIWPFGGYTH; and (vi) an HVR-H3 comprising the amino acid sequence of RWGHSTSPWAMDY.
    • 要解决的问题:提供用于阻断或预防复发肿瘤生长或复发癌细胞生长的抗VEGF(血管内皮生长因子)抗体,以及用于治疗包括慢性炎症或动脉粥样硬化的非肿瘤性病症并提供其组成。解决方案 VEGF抗体包含选自以下六种HVR的HVR抗体:(i)包含X1X2R X3SL的氨基酸序列的HVR-L1 [X1为G或A,X2为V或I,和/或X3为T或R ],其中HVR-L1包含以下位置的任何组合中的1,2或3个取代; (ii)包含DASSLA的氨基酸序列的HVR-L2; (iii)包含SYKSPL的氨基酸序列的HVR-L3; (iv)包含SISGSWIF的氨基酸序列的HVR-H1; (v)包含GAIWPFGGYTH的氨基酸序列的HVR-H2; 和(vi)包含RWGHSTSPWAMDY的氨基酸序列的HVR-H3。
