Biosimilars - Can we do without them? Dr Paul Cornes, Consultant Oncologist, Bristol Haematology & Oncology Centre paul.cornes@yahoo.co.uk Comparative Outcomes Group
Pharmaceutical medicine moves fast! 1984 Nobel Prize for Medicine "for the discovery of the principle for production of monoclonal antibodies". awarded jointly to Niels K. Jerne, Georges J.F. Köhler and César Milstein Yet only 27 years later
We have developed a whole range of new treatments - 1984 to 2012 Monoclonal antibody therapy Head and Neck Cancer Macular Degeneration Multiple sclerosis Breast Cancer Asthma Bowel Cancer Heart disease Leukaemia Transplant rejection Lymphoma Inflammatory bowel disease Ovary cancer Secondary bone cancer Psoriasis Arthritis Melanoma skin cancer Yet only 27 years later http://en.wikipedia.org/wiki/File:Da_Vinci_Vitruve_Luc_Viatour.jpg

I am very fortunate to work with international colleagues Comparative Outcomes Group
We know - there is a cost to cancer Cancer causes the highest economic loss of all of the 15 leading causes of death worldwide cancer has the most devastating economic impact of any cause of death in the world. WHO: Cancer world's top killer since 2010 16.7 percent of all 'healthy' years lost in the European Union The total economic impact of premature death and disability from cancer worldwide was $895 billion in 2008. 83 million years of “healthy life” lost due to death and disability from cancer in 2008. • www.usatoday.com/news/health/2008-12-09-cancer_N.htm • http://www.cancer.org/acs/groups/content/@internationalaffairs/documents/document/acspc-026203.pdf
We know - there is a cost to cancer care …but “cost” may be the wrong word to use – try “investment” instead “Think about health spending as not consumption but investment” David E.

Vaccines Immunostimulants Gene therapy Supportive care Novel approaches Hormonals Cytotoxics Payback on our “investment” is plain to see - Good news for cancer treatment • Cancer death rates are falling • Jemal A, Ward E, Thun M (2010). Declining death rates reflect progress against cancer. PLoS ONE 5(3): e9584. doi:10.1371/journal.pone.0009584 • Novel approaches dominate drug development • Timbs O, Cancer World, 2004; Sept-Oct p.12
The costly war on cancer. The Economist. 2011 May 26. http://www.economist.com/node/18743951 Good news for cancer treatment Drugs in development, 2010 900 drugs in development are for cancer
But it is not all good news – Bad news for cancer treatment • There will be more cancer to treat • World population growth and ageing imply a progressive increase in the cancer burden • 15 million new cases,10 million new deaths are expected in 2020,even if current rates remain unchanged • D Maxwell Parkin. Global cancer statistics in the year 2000. Lancet. 2001;2(9) 01 September • New cancer cases will likely increase to 27 million annually by 2030, with deaths hitting 17 million • http://www.usatoday.com/news/health/2008-12-09-cancer_N.htm
Bad news for cancer treatment • Innovative drug development is slow and expensive • From 5000 - 10000 compounds in pre-clinical trials: • only 0.1% reach clinical trial stage • of these, only 10-20% are finally approved • It takes 15 years from the target discovery to the market at 800 million $/drug • Adams CP et al: Estimating the cost of new drug development: Is it really 802 million dollars?
