PCT No. PCT/EP95/00978 Sec. 371 Date Nov. 17, 1995 Sec. 102(e) Date Nov. 17, 1995 PCT Filed Mar. 16, 1995 PCT Pub. No. WO95/25167 PCT Pub. Date Sep. 21, 1995This invention relates to new anti-EGFR antibodies and single-chain Fvs (scFvs) thereof which can be obtained from phage-antibody libraries constructed from cells of an immunized mammalian, preferably a mouse. Two of the single-chain Fvs isolated from the phage-antibody libraries were engineered to create partially humanized whole antibody molecules. These chimeric anti-EGFR antibodies contain constant regions of human immunoglobulins, and can be used as well as the single-chain Fvs as agents for the diagnosis and therapy of human tumors.
