PHARMACEUTICALS AND GLOBAL HEALTH: INEQUALITIES AND INNOVATION IN THE 21 ST CENTURY ANTIMICROBIAL RESISTANCE AND GLOBAL HEALTH SECURITY UNIVERSITY OF SUSSEX July 19 th 2013 Professor Anthony Kessel Director of Public Health Strategy, Director of Research and Development Public Health England Thanks: Jasper Littmann, Mark Wilcox
Timeline I: Discovery of microbes and the first systematic infection control policies in hospitals Florence Nightingale Louis Pasteur Ignaz Semmelweiss Joseph Lister Anton van Leeuwenhoek 1676 discovery of bacteria antiseptic hand wash Robert Koch 1840s hygiene in field hospitals proposition of germ theory introduction of antiseptic surgery Theory of Miasma Germ Theory causal link between bacteria and disease
Timeline II: From germ theory to antimicrobial therapy Johannes Mikulicz-Radecki Gerhard Domagk Selman Waksman William S. Halstead 1890 introduction of surgical gloves Introduction of surgical masks Surgeon Gen. William Stewart 1897 discovery of penicillin discovery of sulfonamides Pre-antibiotic age Antibiotic age Streptomycin is discovered Alexander Fleming The time has come to close the book on infectious diseases
The War is Over! In 1967, the U.S. Surgeon General William Stewart stated: It is time to close the book on infectious diseases, and declare the war against pestilence won.
Timeline III: From antimicrobial therapy to antimicrobial resistance Streptomycin first used in agriculture First case of MRSA TB & MDR-TB global health emergency 1948 Resistance observed in Staphylococci Treatment for plant diseases Complete drug resistance 1952 S. Dysaentriae outbreak in Japan Methicillin resistance in S. aureus Pre-antibiotic age Post-antibiotic age? WHO declaration First MDR case First confirmed case of completely drug-resistant TB in Mumbai* Penicillin resistance *http://www.bbc.co.uk/news/health

Newly marketed antimicrobial agents in UK 3-year periods 1990–2010 Antibacterial agents Antiviral agents Antifungal agents Antiparasitic agents Antimicrobial Chemotherapy. Eds. Finch RG, Davey P, Wilcox MH, Irving W. OUP, 2012.
Would you develop a new antibiotic if... It took 10 years and cost several hundred million pounds? Chance of falling at the 1 st, middle or last hurdle? If get to market, put on the top shelf (out of reach of most)? If unlucky, arrived at wrong place wrong time? If manage to prescribe, use for 5 days only?
What do we need to do? New national strategy / WHO Optimising Prescribing Practice Improving Infection Prevention and Control Raising Awareness and Changing Behaviour Better research, better evidence Developing new drugs and treatments Improved surveillance Strengthen international collaboration
Super-wicked problems Time for finding a solution to a policy challenge is running out Those seeking to solve the problem are part of the cause Central authorities to address the problem are either weak or non-existent Policy responses discount the future irrationally
For discussion: Change from path dependency Rationing of antibiotic use Create new antibiotics but dont use them New ways to incentivise the drug industry
