  3. Centre for Information & Innovation Law

  4. The problem I. (2009 EU study) • More infections with multidrug-resistant bacteria vs. less R&D in new Abs • Resistance high among Gram-positive & -negative bacteria • Up to 25% or more in several EU Member States • Increasing resistance among Gram-negative bacteria (e.g. Escherichia coli) • Ca. 25 000 EU patients per year die due to multidrug-resistant bacteria . • Extra healthcare costs & productivity losses of at least EUR 1.5 bill. per year. Centre for Information & Innovation Law

  5. The problem II. (2009 EU study) • Only 15 AB-agents with new mechanism of action or directed against new bacteria under R&D with potential to tackle multidrug resistance. • Most in early phases of R&D and primarily developed against bacteria with existing treatment options. • Particular lack of new agents with new targets or mechanisms of action against multi-drugresistant Gram-negative bacteria. • Only 2 (!) such agents with new or possibly new targets and documented activity were identified, both in early phases of development. • A European and global strategy to address this gap is urgently needed. Centre for Information & Innovation Law

  6. Latest data of 2013 Euro barometers on AMR • (EU Commission Survey) • 35% of respondents took antibiotics in the past year, a 5% decrease since the 2009 survey. • 2% fewer people took antibiotics for the flu in 2013 compared with 2009 (18% vs. 20%). • In 2013 more people aware that antibiotics do not kill viruses than in 2009 – 40% vs. 36%.  (ECDC data) • Increasing resistance to carbapenems, a last-line class of antibiotics - ex: - resistant Acinetobacterbaumannii (CRAb) • CRAb show very large variations. Generally higher resistance percentages reported in southern Europe and lower percentages in the north of Europe. • Infections with these multidrug-resistant bacteria are almost impossible to treat. Centre for Information & Innovation Law

  7. US Numbers 2011-2013 • total annual cost of antibiotic resistance ca. US $26 billion • direct mortality from AB resistance infections : 23,000 deaths annually Figure 1 Number of New Molecular AB Entities Approved by the FDA per 5 year period through March 2011.

  8. Multiple reasons for these problems I • Inappropriateuse • Insufficentprecautions and lack of education • Additionalexternal factors/climatechange/travelbehaviour • Insufficient funding of research & collaboration vs. scientificcomplexities • Traditionalpharma innovation system/incentives/business model fails Centre for Information & Innovation Law

  9. Why does the traditional pharma innovation model fail? (P1) Low re-embursement (!) and prescriped for rather short periods (P2) Most effectiveABstodaygeneric or combinationsthereof hard for new products to gainground (lowfruitspicked) (P3) Consumptionintentionallykeptlow for fear of AMR (P4) Neverthessresistance is futile (P5) Highcost & efforts to find new ABs, particularly vs. Gram negative (P6) Particularly complex clinical trials and unpredictable market Centre for Information & Innovation Law

  10. Multiple strategies to tackle the problems • Pro-actions: Conservation& Prevention • Appropriateuse • Prevention of drug resistantinfections • Public awareness • Re-actions : Pushand Pullincentives/mechanisms • More R&D in antibiotics • Legal & regulatoryresponses - Both global & local (glocal) responsesnecessary Centre for Information & Innovation Law

  11. Recent EU Initiatives Centre for Information & Innovation Law

  12. EU Commission in AMR Action Plan 2011 • Call for • ‘unprecedented collaborate research and development efforts to bring new antibiotics to patients’ • by, among other things, launching an IMI programme • ‘for research on new antibiotics aimed at improving the efficiency of research and development of new antibiotics through unprecedented open sharing of knowledge’. Centre for Information & Innovation Law

  13. June 2012: EU Innovative Medicine’s Initiative (IMI) • PPP between EU & European Federation of PharmaceuticalIndustries & Associations (EFPIA) • eachdonate€1 billion ($1,23 billion) to stimulate health innovation. • IMI has initially dedicated €224 million ($275 million) to AB initiative: NewDrugs4BadBugs. Centre for Information & Innovation Law

  14. NewDrugs4BadBugs (ND4BB) • total of €600 million ($738 million) expected to be spent up to 2020. • ND4BB participants: GlaxoSmithKline (GSK), AstraZeneca, Johnson & Johnson, Sanofi , and Basilea etc. • 2 initial Subprojects: • COMBACTE: • improving the efficiency of clinical trials on new antibiotics through better laboratory tests and better trial design. • TRANSLOCATION: - Creation of info and data center, training & networks for researchers, facilitating and increasing the exchange of research data. Centre for Information & Innovation Law

  15. COMBACTE • high quality, pan-European clinical trial network (COMBACTE CLIN-Net) • a pan-European laboratory network (COMBACTE LAB-Net) • 1st antibiotic to undergo clinical trials under COMBACTE is GSK1322322. (inhibiting bacterial enzyme relating to multi-drug resistant respiratory and skin pathogens such as methicillin-resistant Staphylococcus aureus (MRSA)). • 2nd compound to be tested will be MEDI4893. (designed to prevent S. aureus disease by neutralising a specific toxin produced by the bug which results in much tissue and organ damage). Centre for Information & Innovation Law

  16. TRANSLOCATION • Discover important new information to improve selection and optimization of promising molecules in antibiotic drug discovery. • increase overall understanding of how to get antibiotics into multi-resistant Gram-negative bacteria such as E-coli & Klebsiellapneumoniae. • create an information centre for pre-existing and on-going antibacterial research data. • develop guidelines for designing and developing new drugs to tackle AMR. Centre for Information & Innovation Law

  17. EU Commissions Strategy AMR 2013 Roadmap A. Appropriate use of antimicrobials B. Prevent microbial infections and their spread C. Develop new effective antimicrobials or alternatives for treatment D. Global collaboration against AMR spreading from trade, travel & via environment E. Monitoring and surveillance F. Additional Research and Innovation G. Communication, education and training Centre for Information & Innovation Law

  18. EU Commission Memo Nov. 2013 • Six fold increase in the amount being invested, from some €84 million during the EU's 1998-2002 research programme to about €522 million for the 2007-13 period. Centre for Information & Innovation Law

  22. National initiatives: Get pigs off antibiotics 28 JUNE 2012 | VOL 486 | NATURE | 465 Frank Aarestrup explains how he helped Denmark to cut the use of antibiotics in its livestock by 60%, and calls on the rest of the world to follow suit. Centre for Information & Innovation Law

  23. Bacon Boost (with less antibiotics) Centre for Information & Innovation Law

  24. Reasons for the Danish successes • Good and early data indicating problems. • Political will to enforce regulations. • Cross sector collaboration between farmers, researchers & authorities. • Ban of antibiotics & efficient surveillance tracking (“DANMAP” -covering resistance and usage). • No profit incentives for veterinaries from selling/prescribing antibiotics. • Good communication science/society, incl. open debates with industry • No economic growth problems for chicken and pics (to the opposite) due to mart and highly efficient farming techniques Centre for Information & Innovation Law

  25. International cooperation I. • EU Commission, ECDC, EMA, EFSA and national authorities involved in international cooperation to address AMR. • 2009 Collaboration with US via the trans-Atlantic taskforce on AM resistance (TATFAR)- • Objectives :mutual activities and programs relevant to AMR to promote information exchange, coordination and co-operation. • 3 key areas (2011 report) 1. Monitoring and encouraging appropriate use of antibiotics in the medical and veterinary communities 2. Prevention of drug resistant infections 3. Developing strategies to enhance the antibiotic Pipeline • A TATFAR progress report will be published in 2014. Centre for Information & Innovation Law

  26. International cooperation II. • Commission collaborates also with international organizations • On-going dialogue between Commission, China & Russia. • Commission also strongly supports work of WHO. • WHO Expert Committee: • “free market competition best mechanism to achieve affordable new products, but should be accompanied by a delinking of R&D costs and drug price” Centre for Information & Innovation Law

  27. Recent US Initiatives Centre for Information & Innovation Law

  28. GAIN Act in the US (July 9th 2012) • Extends the exclusivity for new antibiotics • Speeds development and review of new antibiotics • Requires additional and/or updated clinical trial guidance • Requires listing of pathogens posing threat to public health Centre for Information & Innovation Law

  29. Progress to date (Oct. 2013) • At least 16 antibiotics as qualified under GAIN • Most are in early R&D sages and may not be approved. • 2 companies submitted market-appl. for GAIN products in late 2013. • GAIN implementation is ongoing. FDA has: • Created AB Drug Development Task Force to develop guidance. • Released draft list of pathogens posing serious threats • Drafted preliminary guidance for companies developing Abs • Reviewed & updated several antibacterial drug development guidelines. Centre for Information & Innovation Law

  30. What’s next? • GAIN important (pull) incentive for moving antibiotics from labs to patients • BUT: New regulatory approval pathway for limited-population AB drugs needed • Pull incentives not always sufficient • 3 main areas in which development incentives can be improved: ■ “Push” incentives, such as R&D tax credits ■ Reforms to streamline and make MA proc. more predictable ■ Reimbursement and pricing reform • More needs to be done to incentivize antibiotic development. • Conservation, sustainability and prevention targets? Centre for Information & Innovation Law

  31. US ADAPT Bill. December 12th 2013 – (cf. EMA adaptive licensing debate & 2013 addendum to the antibacterial guidance) • New accelerated pathway: AB drug developer may request FDA to approve drug “to treat a limited population of patients for which there is an unmet medical need.” • FDA “may rely on tradition. endpoints, alt. endpoints, or combination of tradition. & altern. endpoints; datasets of limited size; pharmacologic or pathophysiologic data; data from phase 2 clinical studies; & other confirmatory evidence as [Agency] deems necessary.” • Improved monitoring & data access: FDA required to use appropriate systems to monitor the use of antibacterial and antifungal drugs , and to monitor changes in bacterial and fungal resistance to drugs. NB: Data made public. • Regular updates on break points: FDA required to “identify upon approval and subsequently update susceptibility test interpretive criteria (“breakpoints”) for AB drugs ¨, including qualified infectious disease products.” Centre for Information & Innovation Law

  32. (Interim) Conclusions • Many EU/US initiativesstartingtotakeeffect • EU Commission: much focus on push mechanism, research & awareness • Pull mechanismsembedded in new EMA guidelines • Gain bill (pull incentive) hudgeimprovement for US • Importanttransatlantic co-operation • ADAPT bill importantnext step • Q: Butwhich solutions aretrulysustainable? Pros & Consof different approaches? Centre for Information & Innovation Law

  33. How to proceed from here? Pros/Cons? • Antibioticconservation: Infectioncontrol, monitoring and rational use? • Reducingdrug developmentcosts by more efficientclinicaltrial regime? • Push incentives: - Governmentalfunding of R&D & taxincentives • Pullincentives for new drug development • Patent term extensionsother IP exclusivities • Prizes & patent buyouts • Orphan drug actmechanisms (pull & push) • Whataboutintegratedapproaches? • Value-basedreimbursement &conservation-basedmarketexclusivity Cf.

  40. New EMA Guidelines (Addendum Nov. 2013) • Recommendations for design of clinical studies intended for antibiotics. • Specifies conditions for primary assessment of efficacy. • With few exceptions not required that primary assessment of efficacy should be confined to patients with a confirmed pathogen relevant to the type of infection under study. • Detailed guidance is provided for studies in five types of infection in which it is accepted that indications for use can be supported by a demonstration of non-inferiority of the test agent to an appropriate comparative regimen. • In indications for which a demonstration of superiority over placebo or an active comparative regimen could be required some suggestions are made for exploring appropriate patient populations and endpoints in the light of the current lack of data to support definitive recommendations for study design. • For acute otitis media recognition is given to accepting evidence of efficacy from non-inferiority studies subject to restriction of the study population and conduct of appropriate analyses. • Limited evidence of clinical safety and efficacy could be accepted to support an initial approval for the treatment of infections caused by MDR organisms for which there are few therapeutic options. • Limited guidance is provided regarding the clinical assessment of treatment modalities intended to exert a local antibacterial effect as a result of direct administration to the site of infection. • Finally, consideration is given to the assessment of efficacy to support use of an antibacterial agent for treatment of some other types of infections.
