Pharmacovigilance for biotherapeutics: Partnering for patient safety

  1. 1. International Federation of Pharmaceutical Manufacturers & Associations Pharmacovigilance for biotherapeutics: Partnering for patient safety Fermin Ruiz de Erenchun IFPMA Biotherapeutics Group Chair (F. Hoffmann–La Roche)1 November 20, 2012 © IFPMA 2012
  2. 2. Types of pharmaceutical products • Chemically-synthesized small molecule medicines – Made by chemical synthesis – Small, simple, low molecular weight – Easy to characterize and purify Example shown: Valium – Rigid and stable in structure2 November 20, 2012 © IFPMA 2012
  3. 3. Types of pharmaceutical products • Biotherapeutic medicines – Biological synthesis using human DNA segments, bacterial or animal cell lines – Large, heterogeneous, high molecular weight – Flexible, labile structure – Difficult to characterize and purify – Complex manufacturing process3 November 20, 2012 © IFPMA 2012
  4. 4. Types of pharmaceutical products CHEMICALLY-SYNTHESIZED SMALL MOLECULE BIOTHERAPEUTIC MEDICINES MEDICINES Produced through a step-by-step chemical Produced with a biological synthesis process synthesis process and derived from proteins and other substances produced by living organisms Characterized by small molecule composition Composed by large and complex molecules which are difficult to characterize Relatively simple organic compounds More sensitive to change and the end product containing few functional molecular groups is determined by a wide range of factors, including the manufacturing process Typically prescribed by a primary care Generally used for the treatment of severe physician and self-administered at home diseases and therefore mostly administered in hospitals with the assistance of medical personnel (with exceptions such as self- administered insulin)4 November 20, 2012 © IFPMA 2012
  5. 5. Types of pharmaceutical products Small molecule Large molecule Large biologic drug drug Human growth IgG antibody hormone ~ 25,000 atoms (hGH) ~ 3,000 atoms Size Aspirin 21 atoms Car Business jet Bike ~ 25,000 lbs (without fuel) Complexity ~ 3,000 lbs ~ 20 lbs5 © IFPMA 2012

  8. 8. Biotherapeutics’ characteristicsunderscore the importance ofpharmacovigilance • A complex production process – Intrinsic variability • A potential for generating unwanted immune responses – Potential for delayed onset adverse reactions Importance of specific traceability8 November 20, 2012 © IFPMA 2012

  13. 13. Current situation for SBP naming Japan Australia US Canada Brazil EU Uses INN USAN Council system, but Adopted Distinct Generally follows works closely recommends non-proprietary No specific policy No specific policy Trade Name be EU system of with WHO to naming using on naming for on naming for used in addition approval for harmonize INN as base SBPs SBPs to distinguish naming names for substances among biotherapeutic products Made exception Draft biosimilar for epoetin SBP guidelines Indicates WHO Example: – gave distinct require Naming policy Naming policy INN system will INN – follow on 1 name differentiation currently under currently under remain INN – follow on 2 Naming policy Naming policy discussion discussion established currently under currently under system in EU discussion discussion13 November 20, 2012 © IFPMA 2012
  14. 14. The INN system • INN plays a central role in: – National pharmacovigilance and traceability systems – National systems for substituting medicines • Limited control over use of existing INNs – Applicant decides if new INN wanted/required – If existing INN is chosen, National Regulators are accountable • Under current WHO criteria, possible for multiple biologics to have the same INN with different clinical characteristics • As a result: no clear INN differentiation between similar products14 November 20, 2012 © IFPMA 2012
  15. 15. IFPMA recommendation The role of INN in pharmacovigilance needs to be further considered • WHO should determine on a global level how current naming system can be applied to retain INN goals – clear identification, safe prescription and dispensing • WHO INN Committee and WHO Pharmacovigilance Committee work together to develop global recommendations for an effective mechanism for tracking and tracing biotherapeutic products – Prevents weakening of INN system – Provides uniform international standard for biotherapeutics – Facilitates linkage of an adverse event with the appropriate product – Promotes communication and exchange of information among health professionals and scientists worldwide15 November 20, 2012 © IFPMA 2012
  16. 16. New Legal Requirements in the EU Article 102 of the Medicinal Products Directive 2011/83/EU, as amended by Directive 2010/84/EU, deals with the identification of medicinal products when reporting adverse events. Article 102(e) provides clarification specifically for biological medicinal products. The Member States shall: (e) Ensure, through the methods for collecting information and where necessary through the follow-up of suspected adverse reaction reports, that all appropriate measures are taken to identify clearly any biological medicinal product prescribed, dispensed, or sold in their territory which is the subject of a suspected adverse reaction report, with due regard to the name of the medicinal product, in accordance with Article 1(20), and the batch number [Emphasis added].16 November 20, 2012 © IFPMA 2012
  17. 17. New EU Pharmacovigilance Legislation* EU Objectives: Strengthen post-authorization regulation of medicines Improve efficiency within the industry Reduce duplication of Member State efforts Increase transparency Opportunities: Improve patient safety Maintain compliance by meeting the new EU PV Legislation Adapting to new treatment developments and innovative therapies Compliance by all stakeholders is therefore of utmost importance! 17* New Regulation (EU) No 1235/2010 and Directive 2010/84/EU on Pharmacovigilance became law on 02 July 2012 and 21 July 2012, respectively
  18. 18. Conclusions • Biotherapeutic medicines are complex products with specific safety issues compared to chemically-synthesized small molecule medicines • Identification and traceability are essential for pharmacovigilance processes – Reporting brand name – Batch number • All stakeholders have a role in ensuring robust pharmacovigilance for biotherapeutics18 November 20, 2012 © IFPMA 2012
