Summary and Highlights
Antibody drug conjugates, a form of immune conjugates, are a burgeoning class of medicines. These medicines, which represent the convergence of chemistry with biology, are composed by linking a monoclonal antibody (mAb) with the cytotoxic drug (often referred to as the payload). ADCs combine the extraordinary affinity and specificity of monoclonal antibodies with the anticancer potential of payloads. Continuous efforts to improve the therapeutic potential of biologics and to develop novel efficacious drugs either by modification or derivatization led to the development of ADCs.

Antibody drug conjugates have revolutionized the field of cancer treatment. Unlike conventional chemotherapeutics, which damage normal cells along with the cancer cells, ADCs target only cancer cells. Through the synergistic combination of monoclonal antibody with the cytotoxic drug, via a stable linker, an extremely efficacious class of anticancer drugs has been emerged. To date, three ADCs have gained entry into the market, of which only two remain. Gemtuzumab ozogamicin (Mylotarg), marketed by Pfizer Inc., became the first FDA approved ADC in 2000.

It was approved for the treatment of relapsed acute myeloid leukemia. In 2010, a decade after its approval, gemtuzumab ozogamicin was withdrawn from the market due to serious hepatotoxicity issues. As of today, only Adcetris (brentuximab vedotin, marketed by Seattle Genetics Inc. and Takeda Pharmaceutical Co. Ltd.) and Kadcyla (ado-trastuzumab emtansine, marketed by Genentech Inc., a member of the Roche Group, are commercially available globally. Adcetris (brentuximab vedotin) was approved in 2011 for relapsed Hodgkin lymphoma and relapsed anaplastic large-cell lymphoma, and Kadcyla (trastuzumab-DM1, or ado-trastuzumab emtansine) was approved in 2013 for HER2 (human epidermal growth factor receptor 2)-expressing breast cancer.

Technological advancements, the growing number of cancer patients and increasing demand for biologics for the treatment of chronic diseases are the prime factors that are driving the market for ADCs. North America continues to lead the market for ADCs as it has the advanced technologies needed to develop ADCs. In addition, rising healthcare expenditures and huge government initiatives are also driving the North American market. Improving economic conditions, demand for better healthcare facilities, increasing health awareness, increasing incidence of chronic diseases and growing R&D activities will help the market for ADCs grow in Asia-Pacific.

The ADC industry involves a specialization business model, more specifically a technology licensing model. In specialization models, certain companies discover and license its ADC technology to pharmaceutical companies. The two main ADC technology companies in terms of sheer numbers of licensing deals to date are ImmunoGen Inc. and Seattle Genetics Inc. ImmunoGen Inc., with its maytansinoid-based targeted antibody payload (TAP) technology, produced Kadcyla with Genentech Inc.

Adcetris is a product of Seattle Genetics' ADC linker and cytotoxin expertise coupled with an antibody from Millennium Pharmaceuticals Inc., now part of the Takeda Pharmaceutical Co. Ltd. Most pharmaceutical companies are investing in the ADC industry typically by forming a collaboration with Seattle Genetics Inc., ImmunoGen Inc. or other ADC technology company.

Innovation in ADCs will occur through the development of new cytotoxic agents as well as new linkers that are adequately stable and at the same time can be cleaved efficiently to deliver the cytotoxic drug. Thus, key future trends in the market for ADCs include the development of novel payloads, new linker

chemistry and the site-specific conjugation technology. All these advancements will lead to the development of more specialized, personalized and targeted ADCs. ADC manufacturing facilities require high capital investment and extensive specialized training of operators and both of these requirements indicates the trend towards the contract manufacturing of ADCs.

Product pipeline is a key determinant of any industry's futuristic growth.

The industry's acceptance of ADC technology is evident from the continual increase in novel ADCs entering clinical trials during the past few years. During 2003-2007, 10 ADCs reached Phase I trials and this number increased to 30 during 2008-2012. About 24 novel ADCs entered Phase I trials during 2012- 2016.

A number of ADCs with promising preliminary data are in the clinical trial pipeline. Mirvetuximab soravtansine, sacituzumab govitecan and vadastuximab talirine are in late stage clinical development (i.e., Phase III trials) and are at the top of the ADC pipeline. These three ADCs are expected to reach the market during forecast period.

An application to the FDA was resubmitted by Pfizer Inc. for regulatory review of Mylotarg (gemtuzumab ozogamicin) in Jan. 2017. The FDA accepted the review of the Biological License Application (BLA) based on additional data from a Phase III study that evaluated the potential benefits of adding Mylotarg to standard induction chemotherapy in AML patients aged 50–70 years old. The FDA's decision on the application is expected sometime in Sept. 2017.

Inotuzumab ozogamicin, an anti-CD22 ADC being developed for the treatment of relapsed or refractory acute lymphoblastic leukemia (ALL), is expected to be approved by FDA at the end of 2017. It received priority review designation from the FDA in Feb. 2017. Through the FDA's priority review program, Pfizer is expected to receive the FDA's decision on ADC inotuzumab ozogamicin (with breakthrough therapy designation) within six months.

The market for ADCs was worth approximately $1.3 billion in 2016 with just two approved drugs, and its potential remains very large. Total revenues, representing product sales (collaboration and royalty revenues are not considered), are expected to be $4.2 billion worldwide by 2021 at a CAGR of 25.5% from 2016 through 2021. These revenues reflect the estimated addition of other ADCs that are directed toward acute lymphocytic leukemia (ALL) and ovarian cancer. Much of the market growth is expected to come from added indications for both the marketed ADCs (i.e., Adcetris and Kadcyla). In addition, the
expected approval of several other ADC molecules, such as Pfizer's gemtuzumab ozogamicin and inotuzumab ozogamicin, during the forecast period will help the market for ADCs to grow significantly.

North America led the antibody drug conjugate market due to the presence of major pharmaceutical companies working on the development of antibody drug conjugate drugs there. Both the North American and European markets benefited from the fast track approval of ADCs. Expanded access to ADCs in Asia-Pacific and the emerging markets drove the market for ADCs in these geographies.

The two most common therapeutic areas for ADCs from 2014 to 2016 were lymphoma and breast cancer, with breast cancer representing 61.3% of ADC revenues in 2016. By 2021, with the approval of two novel ADCs to treat acute myeloid leukemia and ovarian cancer, breast cancer ADCs will represent a market share of 47.1%.
