90Y Clivatuzumab Tetraxetan

The commercial pipeline of recombinant antibody therapeutics is robust and dynamic. As of early December 2014, a total of 6 such products (vedolizumab, siltuximab, ramucirumab, pembrolizumab, nivolumab, blinatumomab) were granted first marketing approvals in 2014. As discussed in this perspective on antibodies in late-stage development, the outlook for additional approvals, potentially still in 2014 and certainly in 2015, is excellent as marketing applications for 7 antibody therapeutics (secukinumab, evolocumab, mepolizumab, dinutuximab, nivolumab, blinatumomab, necitumumab) are undergoing a first regulatory review in the EU or US. Of the 39 novel mAbs currently in Phase 3 studies, a marketing application for one (alirocumab) may be submitted in late 2014, and marketing application submissions for at least 4 (reslizumab, ixekizumab, ocrelizumab, obiltoxaximab) are expected in 2015. Other 'antibodies to watch' are those in Phase 3 studies with estimated primary completion dates in late 2014 or 2015, which includes 13 for non-cancer indications (brodalumab, bimagrumab, bococizumab, MABp1, gevokizumab, dupilumab, sirukumab, sarilumab, tildrakizumab, guselkumab, epratuzumab, combination of actoxumab + bezlotoxumab, romosozumab) and 2 (racotumomab and clivatuzumab tetraxetan) undergoing evaluation as treatments for cancer. In addition to the novel antibody therapeutics mentioned, biosimilar infliximab and biosimilar trastuzumab are 'antibodies to watch' in 2015 because of their potential for entry into the US market and regulatory review, respectively.

The commercial pipeline of monoclonal antibodies is highly dynamic, with a multitude of transitions occurring during the year as product candidates advance through the clinical phases and onto the market. The data presented here add to that provided in the extensive "Antibodies to watch in 2014" report published in the January/February 2014 issue of mAbs. Recent phase transition data suggest that 2014 may be a banner year for first approvals of antibody therapeutics. As of May 2014, three products, ramucirumab (Cyramza®), siltuximab (Sylvant®) and vedolizumab (Entyvio™), had been granted first approvals in the United States, and four additional antibody therapeutics (secukinumab, dinutuximab, nivolumab, pembrolizumab) are undergoing regulatory review in either the US or the European Union. Other notable events include the start of first Phase 3 studies for seven antibody therapeutics (dupilumab, SA237, etrolizumab, MPDL3280A, bavituximab, clivatuzumab tetraxetan, blinatumomab). Relevant data for these product candidates are summarized, and metrics for antibody therapeutics development are discussed.
