Current Challenges of Optimizing Treatment of
Patients with Type 2 Diabetes Mellitus (T2DM)
  • Difficulty in achieving glycemic A1C goal
  • Patients with T2DM often have other CV risk
    factors
  • Dyslipidemia
  • High TG
  • Low HDL-C
  • Increased small dense LDL particles
  • Hypertension
  • Maintaining durable efficacy
  • Assuring patient compliance

Mechanism of Action of PPAR Agonists
  • Peroxisome Proliferator-Activated Receptors
    (PPARs)
  • Receptors located in the cell nucleus
  • PPAR? (fat)
  • ? FFA, ? insulin sensitivity, ? glucose uptake
  • ? plasma glucose
  • PPAR? (liver, muscle)
  • ? FA oxidation, ? apo CIII, ? apo A1
  • ? plasma TG, ? HDL-C

11
Muraglitazar Overview
  • Fred T. Fiedorek, M.D.
  • Vice President,Global Clinical
    ResearchBristol-Myers Squibb

12
Muraglitazar
  • Designed to simultaneously activate two PPARs
  • PPAR? target of thiazolidinediones (TZDs)
    rosiglitazone and pioglitazone
  • PPAR? target of fibrates gemfibroziland
    fenofibrate
  • Muraglitazar a single molecule combining . . .
  • PPAR? insulin-sensitizing anti-diabetic effects
  • PPAR? HDL-C and TG lipid profile effects
  • Expected favorable impact on the vascular
    atherosclerotic/inflammatory process

13
Muraglitazar Pharmacokinetics and Metabolism
  • PK characteristics support once-daily dosing
  • Muraglitazar has high bioavailability based on
    metabolic recovery studies
  • Population PK - no effect of age, gender, or race
  • Primary hepatic elimination into the
    bilemultiple CYP 450 metabolic pathways
  • No clinically meaningful drug-drug interactions

14
Muraglitazar Development Program
  • Development program was designed to address
    benefitsand risks of muraglitazar, a dual PPAR ?
    and ? agonist
  • Non-Clinical Safety Evaluation
  • Results do not indicate that muraglitazar will
    pose a carcinogenic risk to humans
  • Clinical Efficacy Evaluation
  • Muraglitazar is highly efficacious in improving
    glycemic and lipid parameters in patients
    withType 2 diabetes
  • Clinical Safety Evaluation
  • Muraglitazars safety profile is consistent with
    its PPAR? activity

15
Proposed Indication for Muraglitazar
  • Muraglitazar is indicated as an adjunct to diet
    and exercise for the treatment of type 2 diabetes
  • For use in the following settings
  • Monotherapy
  • Combination with metformin
  • Combination with sulfonylureas

Heart Failure and PPAR? Agonists
  • PPAR? agonists reported hazard ratio for heart
    failure of 1.2 to 1.8 compared to other oral
    antihyperglycemic therapy1,2
  • Dose-related increase in plasma volume likely
    responsible for increase in heart failure
  • Heart failure more commonly reported in patients
    with pre-existing ventricular dysfunction
  • PPAR? agonists do not appear to directly affect
    myocardial function

Heart Failure Adjudication in Phase 3
  • Objective to confirm investigator-reported cases
    and to screen for potential undiagnosed heart
    failure events
  • Methods blinded assessment of patients with
    reported predefined adverse event terms
  • Results
  • All except one case of investigator-diagnosed
    heart failure confirmed
  • More than half of the heart failure events were
    due to intercurrent events
  • A small number of events of edema/dyspnea
    adjudicated as mild heart failure resolved with
    treatment while muraglitazar was continued in
    most patients

66
Heart Failure Risk Factors
Phase 3 Short-term and Long-Term
67
Heart Failure Summary
  • Consistent with marketed PPAR? agonists, a low
    incidence of investigator-diagnosed events was
    observed in muraglitazar-treated patients
  • Heart failure incidence
  • Dose dependent
  • Higher in patients with a known AHA/ADA risk
    factor for heart failure
  • Resolved with treatment and discontinuation of
    muraglitazar
  • Infrequently, patients with moderate edema or
    dyspnea were adjudicated to have clinically
    unrecognized heart failure. Symptoms resolved
    with treatment while continuing on muraglitazar.

68
Cardiovascular (CV) Events
  • Imbalance in small numbers of non-fatal CV events
    in one study and fatal CV events in another study
  • Analyzed taking into account differences in
    durationof exposure
  • Discontinued subjects were not followed long-term
  • CV events defined by
  • 52 predefined terms from MedDRA 8.0 dictionary
  • Acute and chronic cardiac and cerebrovascular
    events

69
Predefined CV Events
  • Acute atherosclerotic events
  • Acute atherothrombotic cardiac events(e.g.,
    myocardial infarction, acute coronary syndrome,
    coronary occlusion)
  • Acute atherothrombotic cerebrovascular events
    (e.g., stroke, TIA)
  • CV death, including sudden or unwitnessed death
  • Chronic atherosclerotic events
  • Including angina, coronary artery disease,
    myocardial ischemia

Summary of Muraglitazar Safety
  • Development program confirmed anticipated,
    dose-related, PPAR? agonist-associated risks for
    edema, weight gain, and low incidence of heart
    failure
  • Complete Dataset does not indicate increased
    risks for hepatotoxicity, myotoxicity, CV events
    or cancer
  • Proposed post-approval pharmacovigilance program
    will enrich knowledge regarding safety of
    muraglitazar

Pharmacovigilance,Ensuring Appropriate Use and
Benefit / Risk Summary for Muraglitazar
  • Fred T. Fiedorek, M.D.

82
Proposed Pharmacovigilance
  • Enhanced Pharmacovigilance Plan
  • Events of special interest
  • Unanticipated low frequency events
  • Targeted questionnaires to physicians
  • Periodic, cumulative assessments
  • Pharmacoepidemiology Study
  • Risk assessment
  • Monitor product education and communication
    effectiveness

83
Pharmacoepidemiology Study
  • Objectives
  • To estimate relative incidences of safety events
    with muraglitazar relative to other T2DM
    treatments
  • To characterize T2DM treatment patterns
  • Patient recruitment and follow up will be from a
    large US managed care database (includes
    physician, pharmacy, and hospital claims data)
  • This cohort study will enroll a total of 15,000
    patients
  • 5000 Muraglitazar users
  • 5000 TZD users
  • 5000 Metformin, SU, Insulin
  • Accrual into the study will depend on
    prescription rates
  • Patient experience data will be reviewed
    quarterly for 1st year
  • Active follow up of patients through annual
    questionnaires will begin 1 year after database
    recruitment for next 5 years

84
Plans for Ensuring Appropriate Use of Muraglitazar
85
Muraglitazar Steps to Assure Appropriate Use
  • Key Communication Points
  • Do not use in patients with NYHA Class III /
    IVheart failure
  • Evaluate and treat, if appropriate, patients
    developing edema or dyspnea
  • Any patient developing severe edema, rapid weight
    gain or dyspnea should be evaluated and
    treated,if appropriate, for heart failure
  • Heart failure education for muraglitazar tailored
    fromthe AHA/ADA Consensus Guidance publication
  • Communication Tools to Aid Appropriate Use
  • Patient package insert
  • Healthcare professional communication materials

86
Guiding Principles for Expanding Knowledge
Pharmacovigilance and Assuring Appropriate Use
  • Plans to enrich post-marketing product
    knowledgefor muraglitazar
  • Collection of post-launch safety data
  • Collection of post-launch treatment experience
  • Glucophage (metformin) experience will help to
    guide communication activities for assuring
    appropriate use and tracking patient safety
  • As with all new BMS products, no branded direct
    to consumer advertising for the first year

87
Benefit / Risk of Muraglitazar
88
Treatment of Type 2 Diabetes
  • Need for treatment remains high
  • Patients not at glycemic and/or lipid goals
  • Low durability of efficacy for existing drugs
  • No available single agent meets both glycemic and
    lipid (HDL-C, TG) treatment needs
  • Outcomes trials show that meeting glycemic and
    lipid goals reduces micro and macro vascular
    events

Planned Clinical Outcomes Trial
  • Rationale To demonstrate benefits of dual PPAR
    activation in T2DM
  • Large randomized controlled clinical trial
  • Adjudicated CV outcomes as primary endpoint
  • Duration of approximately 5 years, driven by
    number of required events
  • Design to be finalized following results of
    ongoing trials
  • Muraglitazar
  • PROactive (pioglitazone)
  • FIELD (fenofibrate)

95
Muraglitazar PPARg Agonist-associated Risk
  • Heart Failure
  • Incidence is low and dose-dependent
  • Symptomatic and recognizable to both patient and
    practitioner
  • Manageable with treatment and discontinuation of
    muraglitazar

96
Dosing RecommendationsMuraglitazar 2.5 mg and 5
mg
  • Muraglitazar 2.5 mg
  • Appropriate starting dose in patients with mild
    degrees of hyperglycemia
  • Appropriate starting dose in patients expectedto
    be less tolerant of fluid retention, such as
    NYHAClass II heart failure
  • Titration to 5 mg as necessary to achieveADA
    goals
  • Muraglitazar 5 mg
  • Appropriate starting dose for patients with more
    severe hyperglycemia

97
Proposed Warnings
  • Muraglitazar should not be used in patients with
  • NYHA Class III and IV heart failure
  • Moderate to severe hepatic insufficiency
  • Muraglitazar has not been studied and is thusnot
    indicated
  • For use in combination with insulin
  • For use in pediatric patients
  • Muraglitazar will also not be recommended
  • For use with TZDs and fibrates

98
Conclusion
  • Muraglitazar, the first dual PPARa/? agonist
  • Achieves and maintains glycemic goals
  • Improves diabetic dyslipidemia
  • Muraglitazar has an acceptable safety and
    tolerability profile
  • Events related to fluid retentionwell-characteriz
    ed and manageable
  • Muraglitazar offers a new treatment option for
    patients with type 2 diabetes with a favorable
    benefit / risk assessment
