Patent ID: 10611848

Abstract:
Antibody which binds to the O-acetylated-GD2 ganglioside, includes: a) a light chain including three light chain complementary regions (CDRs) having the following amino acid sequences: CDR1: QSLLKNNGNTFL (SEQ id no 1), CDR2: KVS, CDR3: SQSTHIPYT (SEQ id no 2); and a light chain framework sequence from an immunoglobulin light chain, including the human kappa (κ)CL domain; and b) a heavy chain including three heavy chain complementary regions (CDRs) having the following amino acid sequences: CDR1: EFTFTDYY (SEQ id no 3), CDR2: IRNRANGYTT (SEQ id no 4), CDR3: ARVSNWAFDY (SEQ id no 5), and a heavy chain framework sequence from an immunoglobulin heavy chain, including CH2 and CH3 domains from a human IgG1, and a CH1 domain from a human IgG1, which is mutated to restore pairing between CH1 and light chain that is typical of other human IgG subclasses or substituted by a CH1 domain from such non-IgG1 subclasses as human IgG2, IgG3 or IgG4.
