Association of the British Pharmaceutical Industry (ABPI) The ABPI represents innovative research-based biopharmaceutical companies, We represent large, medium or small companies who… …research and develop the majority of the current medicines pipeline …supply more than 80% of all branded medicines used by the NHS …bring life-saving and life-enhancing medicines to patients. Recognised by government as the industry body negotiating on behalf of the branded pharmaceutical industry for statutory consultation requirements e. g. UK pricing scheme for medicines
Global medicines development The rapid advance of medical progress over the last half-century means that the average child born in the UK in 2030 is expected to live to over 97 years of age. With over 7, 000 medicines and vaccines in development globally for a wide range of diseases, an exciting new wave of medical innovation will play a key role in addressing the challenges faced by patients and by the NHS. Globally, the biopharmaceutical industry is set to invest £ 142 billion a year on R&D by 2022. New medicines offer the potential to revolutionise what it means to be a patient. Going beyond chemotherapy, a blister pack of pills and the often costly, intrusive intervention of surgery, doctors and scientists are discovering new ways to harness the power of the very latest breakthroughs in science to deliver truly personalised treatment. Within the next 5 years cutting edge developments in medicine will transform the lives of patients. Some of the most impactful new therapies in development are: combination therapies for cancer; disease-modifying therapies for Alzheimer’s; antibacterial monoclonal antibodies to target antimicrobial resistance; gene therapies against haemophilia; cell therapies against diabetes; and CAR-T therapies targeting blood cancers. 4

Mortality rates and life expectancy • • • Life expectancy has increased due to our ability to prevent & treat infection (Lister, Pasteur, Koch) Discovery of penicillin by Sir Alexander Fleming and its subsequent development by Florey & Chain revolutionised treatment of infectious disease Antibiotics enable other procedures (surgery, transplants, cancer therapy etc) Crude mortality rates for all causes, noninfectious causes and infectious diseases over the period 1900 -1996. Slide 11
Infectious disease is different When considering prescribing an antibiotic, we need to consider • Treating the patient, eradicating the pathogen • Minimising the effect on the patient’s natural microbiome • Potential impact on the overall population Primary Care Otherwise healthy patients Usually common pathogens (incl Streptococcus, Haemophilus etc) Secondary Care Seriously ill patients Opportunistic pathogens (incl Staphylococcus, Escherichia, Klebsiella) Appropriate prescribing – the right patient, receiving the right medicine, at the right dosage, in the right formulation, at the right time, for the right duration, for the right indication (pathogen and infection site) 12
Infectious disease is different Appropriate prescribing – the right patient, receiving the right medicine, at the right dosage, in the right formulation, at the right time, for the right duration, for the right indication (pathogen and infection site) Primary Care Secondary care • Use only if bacterial (clinically likely or bacteriologically confirmed) • Avoid using if pathogen is likely viral • Need new antibiotics to combat resistant pathogens • Will minimise further resistance to currently used ABs (mostly long-established, generic) • New antibiotics will need clear Appropriate Use ad Stewardship plans to preserve efficacy 13

Antibiotic resistance mechanisms
Antibiotic resistance – A major public health threat Slide 18 18 “Antimicrobial resistance poses a catastrophic threat. If we don't act now, any one of us could go into hospital in 20 years for minor surgery and die because of an ordinary infection that can't be treated by antibiotics” – Professor Dame Sally Davies. Chief Medical Officer, England. March 2013 “A post-antibiotic era means in effect an end to modern medicine as we know it. Things as common as Strep Throat or a child’s scratched knee could kill once again” – Dr Margaret Chan. Director General, World Health Organisation “Owing to the massive threat that it poses to world health and the economy, antimicrobial resistance has finally started to receive the attention it deserves. But awareness is only the first step; to solve the problem, governments, drug makers, and health-care professionals will have to start taking more concrete action” – Lord Jim O’Neill, Author, the UK AMR Review

2018 Update • The commercial reality: By 1990, the diminishing return on investment was leading to a decline in investment in R&D • In 1990, 18 major companies were committed to AB R&D; by 2013 this had dropped to 4 • However; some activity has been stimulated since 2013 • UK has had a leading voice in the global community (David Cameron, Sally Davies, Jim O’Neill) • AMR is a global issue, and many of our members are UK affiliates of global companies 29
2018 Update Most recently, input to: • Health & Social Care Select Committee inquiry • 5 year AMR strategy refresh • NHS 10 -year plan • We work with and through other Industry associations – IFPMA, EFPIA, Ph. RMA, JPMA 30
2018 – Industry Progress AMR Industry Alliance (100 plus companies/associations) • Research & Science o US$2 bn invested in AMR related R&D in 2016 (across 22 companies) • Appropriate Use o 80% of companies are engaged in activities to support Appropriate Use o 90% support surveillance work • Access o Supporting WHO Action plan to improve access to essential drugs • Manufacturing & Environment o 24 Sep 2018: Alliance launched the first list of discharge targets to guide environmental risk assessments for the manufacture of antibiotics 31
2018 – Industry Progress AMR Benchmark (Access to Medicines Foundation) • Research & Development (18 companies assessed) o 40 antimicrobials (28 antibiotics) targeting priority resistant pathogens in clinical development o Vaccines against 12 of the 19 priority pathogens are either in development or on the market o 66 out of 130 projects are being carried out in partnership • Appropriate Access and Stewardship o Access is geographically broader for older products (see WHO EDL) o All 18 companies assessed conduct educational programmes around stewardship o 9 companies support surveillance programmes in a total of 147 countries • Manufacturing & Production o Most companies have environmental risk management plans; discharge limits have now been agreed 32

What would you expect from Industry? • • • Discover new medicines (new mechanisms/classes)? Develop new medicines, through clinical trials, formulation and manufacture, to regulatory approval? Champion Appropriate Use and stewardship – support education to help make the most of what we have? Support surveillance? Investigate new/different approaches – vaccines, phage therapy, oligonucleotides, microbiome ‘transplant’? Commercial reality (to do all this with diminishing returns? ) o Need to create an economic environment in which investment in antibiotic R&D is sustainable 34
What is a good antibacterial target? • The target should be present in a required spectrum of organism. • It should be absent in humans. • It should be essential for bacterial growth. • It should be expressed and relevant to be infection process. • Some thing about the function of target should be known. • Bypass resistance mechanisms? • Completely new approaches? 35
Solutions? 36
Antibiotic resistance mechanisms – and approaches to avoiding them Resistance has always been with us; Fleming warned us in 1945 Efflux pump inhibitors? Beta-lactamase inhibitors eg clavulanate/ amoxicillin 1981 tazobactam/ piperacillin 1993 Iron chelator eg cefiderocol 2018 Membrane permeabilisers? (eg PA-beta-N) 37
Antimicrobial therapy; potential new approaches Value element Definition • Antibodies; vaccines • Antibodies that bind to and inactivate the pathogen, its virulence factors or its toxins; inactivated bacteria or bacterial proteins that stimulate the immune system • Immune stimulation • Proteins or bacterial extracts that boost the immune system • Microbiome/ probiotics • Live micro-organisms (or a set of micro-organisms, incl faecal transplant) that compete with harmful bacteria • Lysins • Enzymes used by bacteriophages to destroy the cell walls of target bacteria • Bacteriophages • Viruses to infect and kill bacteria(wild type or engineered) • Oligonucleotides • Transcription Factor Decoys prevent expression of genes needed for the bacteria to survive and multiply • Peptides • Antimicrobial (direct effect); host defence peptides (enhance host immune response); antibiofilm peptides • Antibiofilm peptides • Benefits of avoiding the spread of infection to the wider population (reduced onward transmission) 38
ABPI – Industry commitment to a global approach • Commitment o Industry is playing its part – in R&D, Access, Appropriate Use and Manufacturing o Need to maintain momentum, we have a fragile consensus, at a tipping point • Collaboration o Industry is ready and willing - with Government and all stakeholders • • Commercial reality o Need to create an economic environment in which investment in antibiotic R&D is sustainable Next Steps o Need to confirm commitment to market entry rewards; pilot a new economic model, de-linking reimbursement from volume usage o Maintain activity - in R&D and education for Appropriate Use o Broaden mandatory surveillance 39
