    Reichert JM. Which are the antibodies to watch in 2013? mAbs 2012;5(1):1.

    The start of the New Year signals that it is time for mAbs’ annual review of the therapeutic monoclonal antibodies (mAbs) in active Phase 2/3 or Phase 3 clinical studies. The entire clinical pipeline currently includes ~350 mAbs, but most of these are in early development. As of the beginning of 2013, our “Antibodies to watch” list includes 28 single mAbs and one mAb mixture that are undergoing evaluation in Phase 3 studies for inflammatory or immunological disorders, cancers, high cholesterol, osteoporosis, Alzheimer disease and infectious disease. In alphabetical order, the 28 mabs are alirocumab, AMG 145, elotuzumab, epratuzumab, farletuzumab, gantenerumab, gevokizumab, inotuzumab ozogamicin, itolizumab, ixekizumab, lebrikizumab, mepolizumab, naptumomab estafenatox, necitumumab, nivolumab, obinutuzumab, ocrelizumab, onartuzumab, racotumomab, ramucirumab, reslizumab, romosozumab, sarilumab, secukinumab, sirukumab, solanezumab, tabalumab, and vedolizumab. The mixture of actoxumab and bezlotoxumab is being evaluated in two Phase 3 studies as a treatment for Clostridium difficile infection.

    As we enter the new year of 2012, the realm of antibody therapeutics development seems full of possibilities for antibodies to watch. The commercial pipeline of antibody-based therapeutics continues to grow and now totals nearly 350 candidates. The molecular diversity of the candidates, especially those for cancer, is remarkable. Modified antibodies such as antibody-drug conjugates (ADCs), bispecific antibodies, Fc or glyco-engineered antibodies and antibody fragments/domains now comprise more than half of the anticancer antibodies at Phase 1, and ~40% of those at Phase 2 and Phase 3. These types of modified antibodies have not been developed as frequently for other disorders–by comparison, ~90% of antibodies developed for non-cancer indications are unmodified IgG–but development of the new formats for inflammatory and autoimmune disorders is expected to grow. In addition, antibody mixtures and antibodies with indirect mechanisms of action (e.g., agonism of immune activation receptors or antagonism of immune inhibitory receptors) are entering clinical study more frequently.
