This application discloses anti-P-cadherin antibodies, antigen binding fragments thereof, and antibody drug conjugates of said antibodies or antigen binding fragments. The invention also relates to methods of treating cancer using the antibodies, antigen binding fragments, and antibody drug conjugates. Also disclosed herein are methods of making the antibodies, antigen binding fragments, and antibody drug conjugates, and methods of using the antibodies and antigen binding fragments as diagnostic reagents. 1. An antibody or antigen binding fragment thereof that binds to human P-cadherin protein at one or more residues selected from the amino acids at positions 124 , 125 , 151 , 153 , 154 , 155 , 156 , 159 , 160 , 161 , 162 , 163 , 168 , 170 , 171 , and 172 of SEQ ID NO:126.2. The antibody of claim 1 , wherein the antibody binds to human P-cadherin protein at the amino acids at positions 124 claim 1 , 125 claim 1 , 151 claim 1 , 153 claim 1 , 154 claim 1 , 155 claim 1 , 156 claim 1 , 159 claim 1 , 160 claim 1 , 161 claim 1 , 162 claim 1 , 163 claim 1 , 168 claim 1 , 170 claim 1 , 171 claim 1 , and 172 of SEQ ID NO:126.3. The antibody of claim 1 , wherein the antibody comprises a heavy chain variable region that binds to human P-cadherin at one or more amino acid residues selected from positions 124 claim 1 , 151 claim 1 , 153-156 claim 1 , and 172 of SEQ ID NO:126.4. The antibody of claim 3 , wherein the heavy chain variable region binding paratope for human P-cadherin protein comprises one or more amino acid residues selected from positions 52 claim 3 , 54 claim 3 , 56 claim 3 , 60 claim 3 , 65 claim 3 , 105 claim 3 , or 107 of SEQ ID NO:128.5. The antibody of claim 1 , wherein the antibody comprises a light chain variable region that binds to human P-cadherin at one or more amino acid residues selected from positions 124 claim 1 , 125 claim 1 , 155 claim 1 , 156 claim 1 , 159-163 claim 1 , 168 claim 1 , 170 claim 1 , and 171 of SEQ ID NO:126.6. The antibody of claim ...
