  1. Developing a RiskMAP Louis A. Morris, Ph.D. Philadelphia, July 16, 2004

  2. Objectives • The New Era of Risk Management • FDA and Product Liability • FDA Draft Guidance: RiskMAP • When will a RiskMAP be needed? • Selected drugs • What will be required for a RiskMAP? • How do I design a RiskMAP for my drug? • Conclusion

  3. New FDA Resources and Plans for Risk Management • Additional FDA resources and enhanced ability to monitor safety of new drugs • PUDFA III authorizes $1.2 billion over five years • 450 new full-time employees • Concept paper and Hearings Held • Draft Guidances Issued May 2004 • To be finalized by end of 2004 More regulators, more things to regulate

  4. FDA’s Refined Concepts • Risk Management:“The overall and continuing process of minimizing risks throughout a product’s lifecycle to optimize its benefit/risk balance.” • Developing Interventions to prevent harm: Risk Minimization Action Plan (RiskMAP)

  5. RiskMAP • A strategic safety program • designed to minimize known product risks while preserving its benefits. • One or more safety goals and related objectives • Uses one or more interventions or “tools” • extend beyond the package insert and routine post marketing surveillance. • Tools are categorized into three areas: • education and outreach, • reminder systems • performance-linked systems. • Draft Guidance describes: • conditions stimulating the need for a RiskMAP, • the selection of tools, • the format for RiskMAPs, and • the evaluation processes necessary to develop and to monitory the success of a risk minimization plan.

  6. When is a RiskMAP Needed? • FDA • the nature of risks verses benefits • risk tolerance issues such as population affected, alternative therapy available and reversibility of adverse events • preventability of the adverse event, and • probability of benefit or success of the risk minimization interventions • Likely Candidates • Drugs that have serious or life threatening contraindications, warnings, precautions or adverse effects • When patient/professional behaviors can mitigate risks • such as pregnancy prevention, blood tests, overdose/misuse avoidance, awareness and action related to specific safety signals • When people other than the patient may be at risk • Such as, a child may use the product inadvertently • Schedule II drugs • Singled out by FDA, with concerns for misuse, abuse, addiction, diversion and overdose as likely candidates for a RiskMAP. Look for Benchmarks, Narrow R/B Tolerances, Preventability, Signals

  7. Examples of Drugs with RM Controls • Accutane (isotretinoin) - severe recalcitrant nodular acne • Actiq (fentanyl citrate) - severe cancer pain • Clozaril (clozapine) - severe schizophrenia • Lotronex (alosetron hydrochloride) - severe irritable bowel syndrome in women • Mifiprex (mifepristone or RU-486) - termination of early intrauterine pregnancy • Thalomid (thalidomide) - erythema nodosum leprosum • Tikosyn (dofetilide) - maintenance of normal sinus rhythm • Tracleer (bosentan) - severe pulmonary arterial hypertension • Trovan (trovafloxacin mesylate or alatrofloxacin mesylate injection) - severe, life-threatening infections • Xyrem (sodium oxybate) - narcolepsy Import Alerts- drugs with RM plans as Benchmarks

  8. Practical Guide • Who should not take “Drug”? • Absolute Contraindications, lab test values, pregnancy status, etc. • How should I take “Drug”? • Timing, delivery system, unique condition • What should I avoid while taking “Drug”? • Other meds, foods, activities • What are the possible or reasonably likely side effects? • Unavoidable, rare but serious Four Medication Guide Questions

  9. Designing a RiskMAP (1) • Must clearly specify risk to be managed • Use PI (or target profile) to select and specify problems to be addressed • Organize and focus on problems needing RiskMAP • Understand the “System” • Processes underlying drug prescribing, distribution and use • Use Root Cause or FMEA analysis to specify sources of system failures Correctly “framing the problem” points to the best solution

  10. Set Goals and Objectives • Plan must specify • overall goals of the RiskMAP • the desired endpoints for safe product use. • The objectives for each goal • must be specific and measurable. • specify the behaviors and processes necessary for the stated goals to be achieved. • For example, if our goal is to prevent pregnancy, then an objective may be that all women must have a negative pregnancy test performed within seven days of initiating therapy.

  11. Tools: FDA Categorization • “Targeted education or outreach.” • health care professionals (e.g., letters; training programs; letters to the editor). • promotional techniques to publicize risk management (e.g., advertisements and sales representatives’ distribution of information). • consumers and patients (e.g., Medication Guides and patient package inserts, limiting sampling or direct-to-consumer advertising) • “Reminder systems.” • training or certification programs, physician attestation, patient agreements), specialized packaging limiting the amount of medication dispensed • “Performance-Linked Access Systems.” • acknowledgment, certification, enrollment, or records • Limiting prescribing to certified health care practitioners, • limiting dispensing to certified pharmacies orpractitioners • Limiting access to patients with evidence of fulfilling certain conditions (e.g., negative laboratory test results). Let’s not spend too much time here

  12. Designing a RiskMAP (2) • Develop a behaviorally predictive model • the set of beliefs underlying behavioral intentions, • the motivations that support or stand in the way of exhibiting desired behavior and • the environmental conditions that facilitate or place barriers to compliance. What do you want people to do?

  13. Behavioral Models • Attitude Change • Understanding Beliefs and Persuasion • Improving Involvement (personal relevance) or Competency (self-efficacy) • Decision making (mental models) • Think and act like experts • Field Theory (barriers and facilitators) • Stages of Change or Precaution Adoption • Emotional Models (fear appeals or positive affect) Choose the Model that best fits the problem

  14. Designing a RiskMAP (3) • Developing Interventions • Selecting Tools • FDA three classes are descriptive but not predictive • Suggest two class categorization • Informational Tools • Use Communication Model to select tools • Distribution Controls • Additional classes of tools available • Economic Controls (incentives for compliance)’ • Product Modifications (reformulations, system delivery) • Combinations and systems improvements Personal view: Tools fit the 4 Ps of Marketing

  16. Tools Selection (FDA) • Necessary And Sufficient for Influencing Behavior • FDA: Selecting Tools • Input from stakeholders • Consistency with existing tools • Documented evidence • Degree of validity and reproducibility Needed: A Rationale Communications Model

  17. Info. Tools Distribution Purpose (strength) Brochure Physician General Education PPI Package/ RPh Risk Communication Medication Guide Package Risk Communication and Methods of Hazard Avoidance Informed Consent Physician Acknowledgement of Risks Warning on Package Package Risk “signal”/compliance Wallet Card Starter Kit Reminder Stickers: Medication Vial or Prescription Medication Vial or Prescription Reminder or time sensitive control message Patient Agreement or Contract Physician Behavioral Commitment Decision Aid Physician Choice of Therapy Video Tape or CD Physician or Starter Kit Persuasion or Emotion Recurring Interventions (telephone calls) Telephone Behavioral Maintenance

  18. Communications Process Goal/Barrier Measure • Exposure Distribution • Attention Readership • Interest Willingness to Read • Understand Comprehension • Accept Attitude Change • Memory Recall/Recognition Tests • Decide Decision Making Scenarios • Behave Intention to Heed/Behavior • Learn Behavior Maintenance Select Vehicles to Maximize Communication Goal May need a combination of Vehicles

  19. How to Select Tools • Select tool(s) to meet communication challenge(s) • What is purpose of intervention, RiskMAP goal • Message is more important than media • Pay attention to content • Distinguish between repetition and redundancy • Mere repetition can wear out, increase cognitive load • Repeat message in new ways to improve likelihood of memory and behavior • Point of influence cues • Timing and situation stimulates behavior How many tools: just enough; 10 is too much, 1 is not enough

  20. Is a Medication Guide Needed? • When product poses a “serious and significant public health concern ...” • Translated: when patient information is necessary to safe and effective use • To apply to between 5 and 10 products annually • Not to be used indiscriminately Adapted from Ostrove, 2001

  21. Triggering Circumstances (201.8) • Could help prevent serious adverse effects • When patient needs to know of serious risks, relative to benefits, that might affect decision to use or continue use • When drug is important to health, and patient adherence to directions is crucial to effectiveness Adapted from Ostrove, 2001

  22. Communications Planning • What do people need to know? • Message must be sufficient to influence behavior • Must affect Knowledge • Be Understood • May need to motivate audience (personal susceptibility, willingness to overcome barriers to resistance, motivate behavior) • How to communicate it? • Develop Communication Objectives • What are the key primary and secondary messages? • Select media based on how people use drug and communication goals • How do I know if it is working? • Pretesting • Evaluation Planning • Will “information” be sufficient? Do we need a “distribution control system”?

  23. Phrasing of Warning Messages • Complete warning: • Signal – this is important • Risk – what is the hazard • Behavior advocated – what to do to avoid risk • Consequence – of failure to heed warning Some parts may be implicit and understood, no need to make explicit Tradeoffs: Comprehensive vs Comprehensible

  24. Determining Content Philou Window • Motivation • Skills

  25. Designing Risk Communications • Reducing Cognitive Load • Use of Communication Objectives • Design with Goal in Mind • Stay On Point • Simple Language • But get the point across • Avoid Seductive Details • Selective Use of Graphic Signals • What is really important, not everything Build a schema consistent with risk avoidance behavior

  26. Distributional Controls Varying Levels of Control Prior Approvals Closed System Special Packaging Record Keeping Certification Clozaril Controlled Substances Actiq Fosamax Tikosyn Thalomid Accutane

  27. Controlled Distribution • MD always Controls Distribution • Additional Limitations by controlling • Who prescribes, dispenses, uses • Conditions of Use • MD with enhanced limitations • Necessary testing • Necessary knowledge qualifications • Necessary evaluation

  28. Distribution Limitations Mandatory vs. Voluntary Debate

  29. System Enhancements • Focus on Outcomes, not Process • Measure knowledge and provide feedback where needed • Immediate: programmed learning • Personalized form to patient • Customized form to MD (patient experience model) • Integration of safety assessment and risk minimization

  30. Multi-Function Registry MD Intervention Doctor MD or Patient Registers Patient Safety Assessment Periodic Multiplatform Delivered Tests RM Evaluation Patient Compilation & Reporting Patient Education & Feedback Iterative Patient Experience Feedback

  31. Multifunction Registry • Survey Risk Knowledge, Attitudes, Intentions • Provide Individual Feedback to MD/Patient • Survey to Evaluate RM Intervention • Combine data to evaluate Impact • Measure Hypothesized ADEs in Registry • Survey forms carefully designed to avoid question-asking biases Create Specialized Benefit-Risk Database

  32. FDA on Evaluation • Select well-defined, validated metrics • Use at least 2 different evaluation methods for key objectives or goals • Compensate for each method’s weaknesses • Pre test and periodically evaluate tools • Make Evaluations Public

  33. Evaluation • PreTesting • Comprehension Testing of Tools • Pilot Testing • LSSS: “real world” assessment in phase IIIb or IV (actual use study) • Multiple Program Evaluation • Database results • Survey results • CQI Review

  34. Comprehension Tests • Need to Test to Determine Understandability • Potential to effect behavioral change • May help with Document Simplification • but not leave out meaningful details • Enhance Liability Protection • Defense against failure to warn • Common for Rx to OTC Switches • Applied to Medication Guides • Informed Consent, Brochures, Videos, etc. • Applied to Physician Labels • Evolving to test decision making, attitudes, intentions

  35. Testing Considerations • Do we need actual patients? • May require study in clinics Study or screening? • Can we generalize from non-patients? • Are experienced patients too knowledgeable? • Important subpopulations (low literacy, younger) • What documents need to be tested? • Key (Core) Communication Vehicles • Testing in what combination – may need field test • What do we want to know from the tests? • Document diagnostics • Suggestions for improvements • Meet Benchmarks – 80% to 85% for primary COs • RM document longer and more complex, need secondary COs

  36. Large Simple Safety Study • Prospectively Designed Phase IIIb • Actual Use Study • Best way to predict outcomes • Limitations • Consent as a possible confounder • MD as an investigator, • Opportunities • Randomly Vary Risk Minimization Interventions • Evaluation reasons for success vs. failure • Learn about many aspects of RiskMAP implementation Wonderful Opportunity

  37. Post-Implementation Evaluation • How can we know the impact of our RM interventions? • Seek behavior change/adherence • If we do not get “sufficient” adherence: • Can we “diagnose” the failure? • Will we be able to revise the plan? • What do we mean by “sufficient” anyway? • Benchmarks or evaluation criteria • Do we need to set these levels a priori?

  38. Evaluation of Goals & Objectives • Evaluation must match specific goals/objectives • Education – measure comprehension, opinions, etc. • Behavior Change – measure by observation & self-report • Limited Use - drug use data base • Reduce ADRs – collect ADR experience • Data Collection Methods • Questionnaires (multiple sampling methods) • Move toward representative sample, not an audit with low response rates • Existing database (administrative, prescribing) • Evaluate Tools pre and/or post launch • Evaluate “unintended consequences”

  39. Existing Databases • Numerous Available • Each has strengths and weaknesses • Some focus on claims (have diagnosis and outcomes) • Some focus on prescribing • Some focus ER visits • May be able to use surrogate indicators • Consider combinations to compensate for individual weaknesses • Limits on explanatory variables

  40. RM Survey Sampling Methodology • Registry • Theoretically an audit, in reality, low response rate • Time Series (surveys) • Concern about prior surveys biasing response • Concern about running out of sample • Consider • Probability Sampling (smaller but scientific sample) • Response rates are in the basement toilet • Bell-Weather (Sentinel Cites) or Quota Sampling • smaller, incentivized sample • Multifunction Registry • integrate marketing and safety purposes • Geographical Testing • Base program for all, add-ons tested for impact

  41. Risk Management Irony Benefits Perceptions Beliefs Safety = Risks Willing-ness to Use Perception of Risk Communications do more than inform, they modify modify beliefs, may change perceptions

  42. Black Box as a Signal QUOTE OF THE DAY"Having a black box on the label is a big deal. It's pretty astounding to go from a year ago thinking this is one of the most benign drugs to a 180-degree turn in the opposite direction." Dr. Susan Hendrix, a gynecologist, on the government decision to require warning labels on drugs containing estrogen.

  44. Continuous Quality Improvements • Seek to avoid All or None Reactions • Add more/redesign tools if current ones not working • Seek to “diagnose” cause for failures • Redesign interventions based on data • Form Committees • Working Committee • Oversight and Review • Periodic Meetings • Each 6 months Benchmarking Success: Seek to improve over time, avoid setting an a priori level

  45. Conclusion • FDA draft guidance is reasonable and responsive to public input • Companies must begin to adapt their thinking to incorporate risk minimization • Ball is in pharma company’s court • FDA will design Risk Minimization Plans if pharmaceutical companies do not • Still in a period of learning, not a lot of successes • Innovation and evaluation is needed
