  1. Review of Tysabri Risk Minimization Action Plan (RiskMAP) Diane Wysowski, Ph.D. Division of Drug Risk Evaluation Office of Drug Safety Peripheral and Central Nervous System Drugs Advisory Committee Meeting March 7-8, 2006

  2. Presentation Outline • Briefly review main features of: -Tysabri RiskMAP goals and methods -Tysabri Registry for PML surveillance -Tysabri Observational Study • Present issues/questions re: above

  3. Sponsors’ Tysabri RiskMAP Goals • To promote informed risk-benefit decisions re: Tysabri use in treatment of MS pts. • To minimize risk of PML • contraindicated in immunocompromised patients • To minimize health consequences of PML (death/disability) thru early diagnosis

  4. Tysabri EnrollmentProcess • Medication Guide provides pt. info. re: Tysabri, PML (death/disability) risk, other safety concerns, instructions to report “any new or continuously worsening neurological symptoms” • Mandatory enrollment of prescribers and patients through Enrollment form

  5. Tysabri Enrollment Process • Mandatory Patient–Physician Acknowledgment Form (Informed Consent) completed and signed by patient and physician • Tysabri forms and Rx sent to sponsor

  6. Patient-Physician Acknowledgment Form Physician acknowledges / signs: • Has read full prescribing information • Is aware of PML risk (disability/death) • Has discussed risk / benefits with pt. • Is prescribing for relapsing MS • Confirms pt. has no contraindications • Has told pt. to report new or worsening neurological symptoms • Is enrolling in Tysabri Registry

  7. Patient-Physician Acknowledgment Form Patient acknowledges / signs: • Has read Medication Guide • Is aware of PML risk (disability/death) • Has discussed risks / benefits with M.D. • Understands need to report to M.D. new or worsening neurological symptoms • Is enrolling in Tysabri Registry

  8. Tysabri Authorization Sponsors plan to: • Enter patient and prescriber M.D. information into Tysabri Registry • Match patient to authorized infusion center • Notify infusion center of pt. authorization to receive Tysabri • Provide center with Pt. Authorization No.

  9. Tysabri Distribution • Tysabri shipped from “centralized distribution system” -one distributor - ≤12 specialty pharmacies -shipped only after receiving patient authorization code from sponsors

  10. Tysabri Administration • Tysabri administered only at trained / authorized infusion ctrs.: -hospital clinic -stand alone clinic -M.D. office • Sponsors estimate ~2,000 authorized infusion centers

  11. Tysabri Administration Infusion Center Nurses To Confirm: • M.D. and pt. enrolled in Registry • Patient has MS (Patient Checklist) • Patient has Medication Guide and has read it (Checklist) • Pt. is not known to be immunocompromised by: HIV, hem. cancers, organ transplants, anti-neoplastic and immunosuppressive drugs (Checklist) • Pt. has not experienced any new or continuously worsening neurological symptoms lasting over several days (Checklist) • Dose administered is documented (Infusion log)

  12. Tysabri Administration • No specific contraindications of Tysabri with concomitant/recent use of: -immune modulator drugs (e.g., interferon beta) -systemic corticosteroids (e.g., methylprednisolone) -other steroid and immune suppressant drugs

  13. Tysabri Administration • Patient Checklist gives examples of a few diseases and six drugs that induce immunocompromise • Sponsors’ focus group wanted “all drugs and diseases that could induce an immunocompromised status clearly spelled out”

  14. Education of Prescribers, Infusion Center Nurses Sponsors propose to: • Deliver ongoing educational info. via mailings, website, toll-free helpline, CME programs • Survey M.D.s and infusion center nurses: -knowledge of Tysabri’s PML risk -appropriate use conditions

  15. Tysabri Registry / Pt. Follow-Up • Sponsors will query prescribing M.D. every 6 months for: -pt. continuation of Tysabri -any PML cases • Length of patient f/u not specified

  16. PML Cases Sponsors plan: • Special assessment (questionnaire, MRI, CSF JC virus) of suspected PML cases for early diagnosis of PML and incidence rate • Submission of data for uncertain diagnoses to external PML expert • Qualitative analyses of PML risk factors

  17. Issue: Maximizing Benefit, Minimizing Risk of Tysabri Should there be Tysabri restriction: • By MS disability severity? • By failure on other MS therapies?

  18. Issue: Minimizing PML Risk Should there be: • Tysabri contraindication for concomitant and recent use of: -immune modulator drugs, -systemic corticosteroids, and -immune suppressant drugs?

  19. Issue: Patient Assessment Should there be: • Periodic M.D. REassessment and REauthorization of patients to receive Tysabri? If so, how frequently? • Assessment by M.D. (vs. nurse) of neurological symptoms and immune suppression before Tysabri administration? • Inclusion on Pt. Checklist of all diseases and drugs that can induce an immunocompromised state?

  20. Issue: Tracking Tysabri Vials Should there be: • One to one patient to vial distribution (each vial associated with a patient) for tight control of Tysabri distribution and tracking?

  21. Issue: Patient Follow-up Aided by: • Real time collection of Tysabri administration, discontinuation, and reasons for discontinuation? • Follow-up of patient deaths thru the National Death Index and collection of death certificates?

  22. Tysabri Observational Study Tysabri observational study (subset of 3,000 U.S. Tysabri Registry patients) followed for up to 5 years after starting Tysabri for: -serious non-PML opportunistic infections -cancer -overall safety profile

  23. Evaluation Re: Tysabri Observational Study • Ascertainment of deaths and causes thru National Death Index and death certificate collection • Inclusion of all patients in Tysabri Registry • Problems in interpretation of etiology -no non-exposed MS controls -availability of population control data

  24. SUMMARY Issues presented should be carefully considered to maximize Tysabri benefits and minimize PML risk.
