SIMILAR BIOLOGICS PART
I
Recombinant
DNA products in the pharmaceutical industry in the global context refer to biologics
that are medicines manufactured and marketed by the inventors. All such
products are initially patented and the product-proprietary rights are vested
upon the inventors. With the passage of time, as and when such medicines are
patent-expired, other new companies start producing them. Worldwide, the
accepted practice for adoption of such patent-expired products for human use in
medicines from manufacturers other than the original inventors are based upon
providing properties of the product manufactured by the new supplier/s as
equivalent to the product of the inventor through processes of identification
of the product physico-chemically, biologically and through accepted clinical
studies on human subjects. Such products introduced by new companies are named in
different countries as “biosimilar products”, “follow-on biologics” and
“similar biologics”. In India, these products are known as “similar biologics”.
The
global market for “similar biologics” is anticipated to grow to USD 10 billion
in 2015. (Source: www.ibef.org). This growth is largely driven by “similar
biologics” going off patent by 2020 worth value of USD 67 billion. (Source:
http://www.gabionline.net/Biosimilars/General/US-67-billion-worth-of-biosimilar-patents-expiring-before-2020). The number of companies likely
to enter into “similar biologics” market would however be large even though the
numbers would be limited, as the lead time is high and would require high developmental
costs. Such “similar biologics” are “different” from “patent-expired small
molecules”, where developmental requirements are much simpler. “Patent-expired”
small molecules are parts of “generic drugs” manufacturing outfits.
The
“similar biologics” industry is fast growing the world over and has a strong
economic value proposition as the profitability prospects are very high. “Similar
biologics” are medicines that are more effective than “generic” drugs and
treatment with “similar biologics” hold the hope of not only providing
increased longevity but also of extending better quality of life, especially in
situations of chronic diseases including diabetes, cardio-vascular diseases,
arthritis and a wide range of cancers. Setting up of “similar biologics”
industry would ensure the availability of such drugs from multiple sources
resulting in market competition and therefore, the prices would also be cheaper
and more affordable than when supplied by the “inventors”.
Worldwide,
because of large and growing market of “similar biologics”, the regulatory
frameworks of all major countries are newly emerging to provide fast structured
approvals so as to enable the consumers to get the benefits of use of such
medicines within a territory. There is however considerable resistance from
certain countries particularly from the US regulators to formally approve the
production of “similar biologics” from new “similar biologics” manufacturers.
Such steps and conditions would not hold for long as the healthcare costs in
any country need to be rationalized and made affordable to suit the needs of poor
and middle class people too, especially in situations where medical costs are not
borne by the state or where patients are not fully covered with medical
insurances.
The
competitive pressure as well as the market for “similar biologics” varies from
country to country. World over, there are “regulated markets” as well as “semi-regulated
markets” for “similar biologics”. The following figure depicts the present
world scenario on “similar biologics” usage:
