Polynucleotides encoding anticoagulant antibodies
View Patent ↗This invention relates to novel antibodies that bind with greater affinity to the factor VIIa/tissue factor (FVIIa/TF) complex than to tissue factor (TF) alone, do not compete for binding to TF with FVII and FX, an inhibit FX activation. The antibodies bind at the site of injury and prevent the initiation of thrombosis. The antibodies can be used to treat a variety of thrombotic conditions including but not limited to deep vein thrombosis, disseminated intravascular coagulation, and acute coronary syndrome.
1. An isolated polynucleotide which encodes an anticoagulant antibody that binds with greater affinity to the factor VIIa/tissue factor (FVIIa/TF) complex than to tissue factor (TF) alone, wherein the antibody does not compete for binding to TF with FVII and FX and wherein the antibody comprises the amino acid sequence of SEQ ID NO:1 or SEQ ID NO:3.
2. The isolated polynucleotide of claim 1 which comprises the nucleotide sequence SEQ ID NO:2 or SEQ ID NO:4.
3. The isolated polynucleotide of claim 1 which is in a gene therapy vector.
4. The isolated polynucleotide of claim 1 which is a cDNA.
5. The isolated polynucleotide of claim 1 which is a synthetic DNA.
