Risk Management Programs FDA Experience and Evolving Guidances on Risk Management Practices Anne Trontell, M.D., M.P.H. Deputy Director CDER Office of Drug Safety Anesthetic & Life Support Drugs Advisory Committee September 9, 2003
FDA and Risk Management • Longstanding role in weighing risk information in context of drug approval • Nomenclature of risk mgt initiated with 1999 Commissioner’s Report on Managing the Risks of Medical Products
FDA and Risk Management • PDUFA3 formalized FDA role in risk management • PDUFA3 calls for FDA to develop three interrelated guidances on risk management by Sept 30, 2004 • Topics • Premarketing Risk Assessment • Pharmacovigilance/ pharmacoepidemiology • Risk Management per se
FDA and Risk Management • Preliminary thinking published and presented April 2003 as “Concept Papers” to solicit public input • Draft guidances based on concept papers and commentary are anticipated for release this fall
Presentation • Focus on FDA experience with risk management • Draws upon concepts from concept paper on “risk management programs” • Snapshot of a rapidly evolving approach to drug safety
“Risk Management Programs” Concept Paper • Focus on risk minimization efforts • Efforts termed risk management programs (RMPs) in concept paper • Risks identified using practices described in two other PDUFA3 documents
Important Concepts • Safe means that: • beneficial actions outweigh harmful or undesirable side effects • does not suggest absence of risk • Risk Management Program (RMP) • strategic safety effort to reduce risk: >1 risk reduction goal >1 intervention (tool) other than PI • PI= Professional package insert or FDA approved product labeling; not an RMP of itself
RM Program Goal(s) • Tailored to product’s specific risk concerns • Describe ideal product use scenario or desired end result of RMP • Include “Vision statement” of optimal drug use scenario, • thalidomide: No fetal exposures • clozapine: No agranulocytosis
When is an RMP Appropriate? • Whenever risk reduction needs emerge during a product’s lifecycle • Sponsor may volunteer or FDA propose • “When the number or severity of a product’s risks appears to undermine the magnitude of benefits in an important segment of actual or potential users.”
How to Assess WhetherRisks Undermine Benefits? • No simple formula compares risks to benefits • Risks and benefits vary in types, measurements • Case-by-case judgments required by sponsor and/or FDA on whether to develop, submit, and implement an RMP • FDA expects most products will be handled by package insert (PI), without formal RMP
RMP Tools • Risk management tool (intervention): a process or system intended to enhance safe product use by reducing risk • Choice of tools influenced by severity, reversibility and rate of risk
Categorization of Tools in Current Risk Mgt Programs Education & Outreach “Guiding” Systems Restricted Access
Education and Outreach • In concept paper, efforts other than professional labeling (also known as “package insert”, PI) • Healthcare Professional (HCP) letters and other public notices • Training programs and CE for credit • Patient-oriented labeling • Medication Guides (MG) • Patient Package Inserts (PPI)
Medication Guides • FDA approved patient labeling • Regulated since 1999 (21 CFR Part 208) • Required dispensing by pharmacists with each prescription • Primarily for outpatient Rx products with serious & significant public health concerns • planned 5-10 products per year
Medication Guides • Three triggering criteria At least one criterion must be met • pt labeling could help prevent serious AEs • serious risks: could affect pt decision to use • pt adherence to directions crucial to effectiveness • CFR 208.20 specifies format and content
Medication Guides • Now 13 Medication Guide texts covering 22 different products • Cover diverse risks: include but not limited to hepatotoxicity, teratogenicity, abuse and diversion, overdose
Patient Package Insert (PPI) • FDA approved patient labeling • Required distribution to patients under CFR 310.515 for drug products containing estrogens, otherwise optional • Subject to CFR 202 when used as brief summary for DTC ads
Patient Package Insert (PPI) • Many follow Medication Guide format & content to promote consistency in FDA-approved patient labeling • Unit-of-use packaging with PPIs can function similarly to Medication guide
PPI vs. Medication Guide • Medication guides required to be dispensed with medications to patients • PPIs other than estrogens: optional • Generic products have same Medication Guide requirements as innovator
Systems Guiding Prescribing, Dispensing, Use • Purpose is to assist individuals in following appropriate prescribing practices • Alternatively stated, make it difficult to forget important safety processes • May use a variety of reminders, prompts
Systems Guiding Prescribing, Dispensing, Use • Patient agreements/informed consent • Practitioner certification programs • Special conditions of dispensing • special packaging • limited supply / no refills • check mechanisms to assure appropriate prescribing
Example of Special Packaging Gamma-hexachlorocyclohexane (Lindane®) • Volume limited to 1 or 2 ounces due to risks of seizures, death with OD
Example of Product with Multiple Guiding Systems Alosetron • Patient agreement • Physician attests to knowledge of IBS and product risks to obtain stickers for Rx • Stickers: indicate M.D. expertise, appropriate patient selection, agreement • Pharmacists look for stickers on Rx prior to dispensing
Restricted Access Systems • Link drug product access to compliance with RMP elements • e.g. clozapine: “no blood, no drug” • Often limit prescribing and dispensing to selected HCP and pharmacists • May require documentation of safe use conditions (such as lab tests) before dispensing to patients
Example of Restricted Access: Thalidomide System for Thalidomide Education and Prescribing Safety (S.T.E.P.S.) • Product shipped only to registered pharmacists • Pharmacists dispense thalidomide Rx only if • patient & prescriber are both registered • central authorization of information from provider and patient of nonpregnant status
Selecting and Developing ToolsConsider: • Stakeholder input on feasibility, acceptance • prescribers, pharmacists, pts, payors • Consistency: with existing/accepted tools • Evidence: past effectiveness in similar product or related objective • Public comments to FDA: Preserving patient access to benefits of drugs
Subpart H • Subpart H (CFR 314.500) regulatory approval option for surrogate endpoints or for restrictions to ensure safe use • May include restricted access
Subpart H • Restricted access/distribution can be done without approval under Subpart H • Subpart H: affords option of more rapid product withdrawal, FDA review of promotional materials prior to publication
Evaluation of RMP • Important to measure • Effectiveness & value-added of tools • Progress towards goal(s) • Changes in health outcomes • Allows modification of RMP to meet goals
Evaluation of RMP • Overlap with concept paper on pharmacovigilance and pharmacoepidemiology • Active or targeted surveillance systems may serve • as means of measuring RMP goals, objective • way to determine if RMP is effective
Summary: Risk Management Programs • Sparingly applied interventions • Intended to minimize identified risks • Are goal-oriented • Use tools commensurate with risks and benefits • Merit evaluation
Summary: RMP Tools Category: Education & Outreach • Many types, can be general or targeted • Applied to many drugs • Limited intrusion on conventional prescribing, dispensing, and use processes • Data on effectiveness are limited and mixed
Summary: RMP Tools “Guiding” Systems • Limited number of systems in use • Moderate intrusion on conventional prescribing, dispensing, and use processes • As yet, no evidence on effectiveness but evaluations are planned for several programs
Summary: RMP Tools Restricted Access • Limited number of systems in use • Applied to date for products with limited therapeutic alternatives, significant risks • User populations typically small
Summary: RMP Tools Restricted Access • Most intrusive on prescribing, dispensing, use • Closed systems, easy to evaluate • Data • support effectiveness in risk minimization • show instances of slow product uptake with substitution of alternative products
