the home of Business Intelligence Biosimilars: Pipeline Trends, HC , December 2011 © Datamonitor 3 Key findings (1/3) Datamonitor has identified a total of 397 biosimilars/copy-biologics across 125 companies as being in development/marked. Products and pipeline candidates were identified using publically available information (where available). For each candidate, the stage of development was determined using company reported information as well as secondary sources such as clinical trial databases. Marketed products – Biosimilar and copy-biologic markets are dominated by versions of simple biologic molecules such as erythropoietin, somatropin, filgrastim and insulin products. Pipeline candidates – There is an increasing trend towards the development of high value biologics such as monoclonal antibodies (MAbs), fusion proteins, and second-generation biologics, with 57 MAb biosimilar candidates currently in development, versus only 46 therapeutic protein candidates. Rituximab is the most targeted molecule, with 14 pipeline biosimilar candidates currently in development. Target therapy areas/indications – Reflecting the focus on MAbs and therapeutic proteins such as erythropoietin and filgrastim, oncology, neutropenia and anemia as well as various cancer and immunological and inflammatory indications are the most frequently targeted by developers. Geography – The EU leads in terms of the number of marketed and pipeline biosimilar candidates followed by South Korea, while India continues to lead the way in the copy-biologics market, followed by China. Company – Based on company reported information, Sandoz was highlighted as the leading company in terms of marketed and pipeline biosimilars, while Zydus Cadilla leads in terms of copy- biologic development.

the home of Business Intelligence Biosimilars: Pipeline Trends, HC , December 2011 © Datamonitor 13 Rituximab is the biologic most targeted by biosimilar developers Leading molecules targeted by biosimilar developers Source: Datamonitor; company-reported information, 2011  Rituximab has received significant attention from biosimilar developers, with 14 candidates at various stages of development (from planned to Phase III clinical trials).  Herceptin (trastuzumab; Roche) is the only MAb used in the treatment of HER2- positive metastatic breast cancer. It has also been a major target for biosimilar developers, with eight candidates currently in development.  Biosimilar developers are also looking to develop other more complex products such as biosimilar versions of second- generation biologics such as pegfilgrastim, darbepoetin alfa, and pegylated interferon alfa. These drugs have improved half-lives and dosing regimens over their first- generation counterparts.

the home of Business Intelligence Biosimilars: Pipeline Trends, HC , December 2011 © Datamonitor 14 Simple biologics dominate the copy-biologic market Leading molecules targeted by copy-biologic manufacturers, 2011 Source: Datamonitor; company-reported information, 2011  There are currently 36 copy-biologic versions of filgrastim, 31 copy-biologic versions of erythropoietin, and 25 copy- biologic insulins at market, with these products accounting for 49% of all copy- biologics currently available.  Due to the rising prevalence of diabetes in emerging markets, together with the high cost of advanced insulin products such as insulin glargine and lispro, lower cost human insulin and bovine/porcine insulins will continue to prove popular among copy-biologic manufacturers and patients.  Interferon alfa-2a and -2b products have proved to be popular molecules. Hepatitis C virus infection is particularly prevalent in many emerging markets, and as a result companies have tapped into this lucrative market.

This group represents 11 different molecules across a variety of oncology and associated indications, from simple biologics such as filgrastim to more complex high value targeted therapies such as trastuzumab.  Diseases within the immunology and inflammation field have also received significant attention from biosimilar developers, with 35 candidates currently in development across a number of distinct indications. The molecules for which there is active clinical development within this group include infliximab, etanercept, adalimumab, and rituximab.

This group is primarily made up of copy-biologic versions of molecules. The majority of these products are filgrastim, which are low cost and easy to produce by manufacturers, and affordable to patients.  The infectious disease group consists exclusively of interferon alfa and peginterferon alfa copy-biologics for the treatment of hepatitis C virus infection, which is particularly prevalent in many emerging markets.

the home of Business Intelligence Biosimilars: Pipeline Trends, HC , December 2011 © Datamonitor 17 India dominates the market in terms of approved products Leading countries for biosimilars and copy-biologics development, 2011 Source: Datamonitor; company-reported information, 2011  In terms of launched copy-biologics, India leads the way with 59 products (encompassing 22 molecules), followed by China with 39 products (16 molecules), followed by the Latin American markets of Argentina, Mexico, and Brazil.  Argentina's ANMAT published biologics and biosimilar approval guidance in September  In Mexico, despite the creation of biosimilar guidelines in 2009, the pathway remains impossible to navigate. However, copy-biologics have existed in the country for a number of years, are accepted by patients and physicians alike, and are often considered to be interchangeable with branded products.  Brazil has traditionally been a small market for biologic products given the low rates of reimbursement. However, legislation relating to biosimilars was introduced in 2005.

However, given the limited availability of company-reported development information, the size of the Indian pipeline may be under-represented here.  While only having launched six products to date, South Korea is ranked third in terms of biosimilar development with 29 candidates (13 molecules) currently in development.

Omnitrope (somatropin; Sandoz) was the first biosimilar to be marketed in the EU, Japan, Australia, and Canada.

The remaining companies are all India-based, with the exception of Sedico, based in Egypt.

the home of Business Intelligence Biosimilars: Pipeline Trends, HC , December 2011 © Datamonitor 22 Biosimilar/copy-biologic company analysis (4/4) Biosimilar and copy-biologic MAb development activities, 2011  Overall, 30 companies have biosimilar/copy-biologic MAbs in their portfolios, with Reditux (rituximab; Dr. Reddy’s) currently being the only copy- biologic MAb on the market.  BioXpress leads in terms of the number of MAb candidates. However, all 16 are "planned," with no reference to any clinical development having been initiated (BioXpress, 2011).  Celltrion currently has eight MAb candidates, two of which are in clinical development, with five in preclinical development and a further one at the “planned” stage. These eight biosimilars are due to appear in the US, Europe, Australia, Canada, and New Zealand through a marketing agreement between Hospira and Celltrion signed in October 2009 (Berkrot, 2009).
