  • VHH antibodies are derived from the variable region of the heavy chain-only antibodies found in the camelid family and have a molecular weight of only about 15 kDa. This small size allows them to access and bind to epitopes that are inaccessible to larger antibodies and also makes them more stable in harsh environments such as the gastrointestinal tract or extreme temperatures.
  • VHH antibodies have shown promise as therapeutics for a wide range of diseases, including cancer, autoimmune disorders, and infectious diseases. Due to their unique properties, VHH antibodies have the potential to overcome some of the limitations of traditional antibodies and may offer new opportunities for the development of therapeutics.
  • the antibodies of the present disclosure are conjugated to a therapeutic agent, such as a radionuclide.
  • Radionuclides are unstable atomic nuclei that emit radiation in the form of alpha, beta, or gamma particles in order to become more stable. These particles can be harnessed for a variety of purposes, including medical imaging, cancer treatment, and industrial applications. For example, alpha emitters are highly effective at killing cancer cells because they release high-energy particles that can only travel a short distance, while beta emitters are useful for imaging and therapy because they can penetrate deeper into tissue.
  • Radionuclides used in therapeutics, for example are often attached to targeting molecules, such as antibodies, peptides, or small molecules, in order to deliver the radiation directly to a specific cell or tissue.
  • Radionuclides have been used in a range of diagnostic and therapeutic applications, including PET imaging, SPECT imaging, radioimmunotherapy, and targeted radionuclide therapy.

  • an anti-5T4 antibody as described herein has a suitable binding affinity for the target antigen (e.g., human 5T4) or antigenic epitopes thereof.
  • binding affinity refers to the apparent association constant (KA).
  • the KA is the reciprocal of the dissociation constant (KD).
  • KD dissociation constant
  • An increased binding affinity corresponds to a decreased KD.
  • Higher affinity binding of an antibody for a first antigen relative to a second antigen can be indicated by a higher KA (or a smaller numerical value KD) for binding the first antigen than the KA (or numerical value KD) for binding the second antigen.
  • an antibody has specificity for the first antigen e.g., a first protein in a first conformation or mimic thereof) relative to the second antigen (e.g., the same first protein in a second conformation or mimic thereof; or a second protein).
  • the anti-5T4 antibodies described herein have a higher binding affinity (a higher KA or smaller KD) to human 5T4 as compared to the binding affinity to 5T4 of a different species. Differences in binding affinity (e.g., for specificity or other comparisons) can be at least 1.5, 2, 3, 4, 5, 10, 15, 20, 37.5, 50, 70, 80, 91, 100, 500, 1000, 10,000 or 10 5 fold.
  • any of the anti-5T4 antibodies may be further affinity matured to increase the binding affinity of the antibody to the target antigen or antigenic epitope thereof.
  • Binding affinity can be determined by a variety of methods including equilibrium dialysis, equilibrium binding, gel filtration, ELISA, surface plasmon resonance, or spectroscopy (e.g., using a fluorescence assay).
  • Exemplary conditions for evaluating binding affinity are in HBS-P buffer (10 mM HEPES pH7.4, 150 mM NaCl, 0.005% (v/v) Surfactant P20). These techniques can be used to measure the concentration of bound binding protein as a function of target protein concentration.
  • the concentration of bound binding protein [Bound] is generally related to the concentration of free target protein ([Free]) by the following equation:
  • the anti-5T4 antibodies described herein bind to the same epitope in a 5T4 antigen (e.g., human 5T4) as a reference antibody known in the art.
  • the reference antibody is PF-06281192 (huAlmAb).
  • An antibody that binds the same epitope as a reference antibody described herein may bind to the same epitope or a substantially overlapping epitope (e.g., containing less than 3 non-overlapping amino acid residue, less than 2 non-overlapping amino acid residues, or only 1 non-overlapping amino acid residue) as the reference antibody. Whether two antibodies compete against each other from binding to the cognate antigen can be determined by a competition assay, which is well known in the art.
  • Such antibodies can be identified as known to those skilled in the art, e.g., those having substantially similar structural features (e.g., complementary determining regions), and/or those identified by assays known in the art.
  • competition assays can be performed using one of the reference antibodies to determine whether a candidate antibody binds to the same epitope as the reference antibody or competes against its binding to the 5T4 antigen.
  • the anti-5T4 antibodies described herein may comprise a complementary determining region 1 (CDR1), a complementary determining region 2 (CDR2), and a complementary determining region 3 (CDR3).
