Antibody drug conjugates are monoclonal antibodies that are attached with
biologically active drugs. The combination of cytotoxic drugs and the
targeting capacity of molecular antibodies allows antibody drug
conjugates to perform targeted therapy to treat cancer patients. This
allows a sensitive discrimination between cancerous tissues and
healthy tissues. As the global antibody drug conjugates market is in
an infancy stage, only three antibody drug conjugates have received
market approval from the United States Food and Drug Administration
(FDA).
The
first among the three, Mylotarg, was withdrawn from the global market
by its manufacturer, Wyeth, Inc., a company of Pfizer, Inc., in June
2010. Mylotarg was primarily used for treating acute myelogenous
leukemia. Thus, by drug, the global antibody drug conjugates market
is now classified into Kadcyla and Adcertis.
Adcertis
(Brentuximab vedotin) is a special antibody drug conjugate that is
directed towards the CD30 protein and is expressed in systemic
anaplastic large cell lymphoma and Hodgkin lymphoma. Seattle
Genetics, in Feb 2011, submitted a Biologics License Application to
the United States FDA for use in refractory Hodgkin lymphoma and
relapsed anaplastic large cell lymphoma. The drug received
accelerated approval from the United States FDA in August 2011.
Adcertis led the global antibody drug conjugates market during the
period between August 2011 and February 2013. In October 2012,
Adcertis received marketing authorization from the European Medicines
Agency.

Kadcyla
(Trastuzumab emtansine) is an antibody drug conjugate that consists
of the monoclonal antibody trastuzumab and is linked to cytotoxic
agent mertansine DM1. In Italy, clinical trials on women suffering
from HER2 positive breast cancer showed that Kadcyla improved their
survival by 5.8 months. Due to this, Kadcyla received approval from
the United States FDA in February 2013. Kadcyla, developed by
Genentech, Inc., a subsidiary of F. Hoffmann-La Roche AG, is
manufactured by Lonza group. The introduction of Kadcyla boosted the
growth of the global antibody drug conjugates market during the
period between 2012 and 2013.
By
geography, the global antibody drug conjugates market is divided into
Asia Pacific, North America, Europe, and Rest of the World. Most
antibody drug conjugates in the development phase are for oncological
indications and are propelled by the easy availability of monoclonal
antibodies that target various types of cancer. At present, leading
players in the global antibody drug conjugates market are targeting
different domains other than oncology to develop antibody drug
conjugates.
The
high cost involved in the research and development activities to
discover new antibody drugs is expected to restrict the growth of the
global antibody drug conjugates market in the years to come. Biotest
Pharmaceuticals Corporation, Synthon BV, Bayer AG, and Immunomedics,
Inc. are some of the leading companies in the global antibody drug
conjugates market.
