Recently, the World Health Organization (WHO) introduced new definitions for the assignment of antibody international nonproprietary names (INN). The modifications that already have been effectuated change the way in which therapeutic antibodies are classified as chimeric, humanized and human antibodies. Unfortunately, the new definitions have several major limitations that are unworkable – click here for Paul Carter’s summary.
The Antibody Society intends to represent the Antibody Community at large at an Open Session of the WHO in Geneva on April 12, 2016, and request urgent modifications that address the problems with the new system. To be able to influence the WHO, we need your support. You can support our effort by agreeing to the statement here and provide your name and information.
Antibodies to watch in 2016
Seven novel antibody therapeutics (begelomab, bezlotoxumab, brodalumab, ixekizumab, obiltoxaximab, sarilumab, reslizumab) are undergoing regulatory review as of December 2015, and thus may gain their first approvals in 2016. Commercial late-stage antibody therapeutics development has exceeded expectations by increasing from 39 candidates in Phase 3 studies as of late 2014 to over 50 as of late 2015. Of these candidates, transitions to regulatory review by the end of 2016 are projected for 8 (atezolizumab, benralizumab, bimagrumab, durvalumab, inotuzumab ozogamicin, lebrikizumab, ocrelizumab, tremelimumab). Other “antibodies to watch” include 15 candidates (bavituximab, bococizumab, dupilumab, fasinumab, fulranumab, gevokizumab, guselkumab, ibalizumab, LY2951742, onartuzumab, REGN2222, roledumab, romosozumab, sirukumab, Xilonix) undergoing evaluation in Phase 3 studies that have estimated primary completion dates in 2016. As evidenced by these therapeutics, the biopharmaceutical industry has a highly active late-stage clinical pipeline that may deliver numerous new products to the global market in the near future.
2015: An extraordinary year for first marketing approvals of antibody therapeutics
The number of novel antibody therapeutics that received a first marketing approval in 2015 exceeded expectations, with 8 (alirocumab (Praluent®), elotuzumab (Empliciti®), evolocumab (Repatha®), daratumumab (Darzalex®), dinutuximab (Unituxin®), idarucizumab (Praxbind®), mepolizumab (Nucala®), necitumumab (Portrazza)) granted their first approval as of late December. A total of 9 antibody therapeutics were granted a first US approval in 2015, including all 8 antibodies noted above as well as secukinumab (Cosentyx®), which received a first approval in Japan in 2014. In the European Union, the European Commission also granted marketing approvals to 9 antibody therapeutics in 2015, including 5 antibodies noted above ((alirocumab (Praluent®), evolocumab (Repatha®), dinutuximab (Unituxin®), idarucizumab (Praxbind®), mepolizumab (Nucala®)) and 4 products that had been previously approved in another country. A table of therapeutic monoclonal antibodies approved or in review in the European Union or the United States can be found in the Members Only section of The Antibody Society’s website.
AIRR Community: “Look Ma, In the News Again!”
Another example of the critical importance of data sharing in immune profiling and the need for data standards in the recent editorial “No Sample Left Behind” in Nature Biotechnology, 33(10). Explicit mention of the AIRR Community May Meeting (through a link to PDF of the schedule) means that not only do people think this is important, but the AIRR Community is starting to see some recognition.
I love this quote from the article: “For the moment, however, cross-insitutional efforts remain the exception rather than the rule. For immune profiling research to truly fulfill its potential, now is the time for the community to come together and agree on standardized sample collection and storage and the benefits of pooling data. We must open up the freezers and unlock the data. No sample should be left behind.“
AIRR Community efforts mentioned in Nature
The Nature article “The Cell Menagerie: Human Immune Profiling” by Marissa Fessenden (Nature V. 525, Sep 17, 2015) discusses the importance of vaccines and understanding the immune response. A large number of the groups mentioned in the article are key players in the AIRR Community, including G. Georgiou (UT Austin), Steve Kleinstein (Yale), Lindsay Cowell (UT Southwestern Medical School), and Jamie Scott (Simon Fraser University). An unintended shout out to the AIRR Community’s work!
