Abstract
The present invention provides a humanized antibody or antibody fragment comprising (a) a humanized light chain comprising 1) Complementarity Determining Region (CDR)-L1, the sequence of which is identical to the sequence of SEQ ID NO: 3; 2) CDR-L2, the sequence of which is identical to the sequence of SEQ ID NO: 4; and 3) CDR-L3, the sequence of which is identical to the sequence of SEQ ID NO: 5, and (b) a humanized heavy chain comprising 1) CDR-H1, the sequence of which is identical to the sequence of SEQ ID NO: 6; 2) CDR-H2, the sequence of which is identical to the sequence of SEQ ID NO: 7; and 3) CDR-H3, the sequence of which is identical to the sequence of SEQ ID NO: 8, as well as methods for treating, diagnosing, and monitoring the progression of HIT. The present invention also provides methods for assessing the antigenicity and ability to cause HIT of anionic anticoagulants. The present invention also provides a mutant protein which has the same amino acid sequence of a wild type PF4 monomer except that (i) at least one amino acid of the wild type PF4 monomer has been deleted, (ii) at least one amino acid of the wild type PF4 monomer has been replaced by another amino acid, or (iii) a combination of such changes has been made. The present invention also provides methods of treating or reducing the likelihood of HIT, treating angiogenesis, treating abnormal cell growth, or affecting coagulation pathologies that lead to thrombus formation, by administering such mutant proteins to a patient.
