American Diabetes Association 2008 Annual Meeting Investor Reception and Webcast Amylin Pharmaceuticals, Inc. June 8, 2008 Safe Harbor Statement This presentation contains forward-looking statements about Amylin. Our actual results could differ materially from those discussed due to a number of factors, including: risks that BYETTA and/or SYMLIN and the revenues we generate from these products, may be affected by competition, unexpected new data, technical issues, or manufacturing and supply issues; our financial results may fluctuate and may not meet market expectations; our clinical trials may not start when planned and/or confirm previous results; our pre-clinical studies may not be predictive; NDAs for our product candidates and sNDAs for our label expansion requests may not be submitted timely or receive regulatory approval; we may not be able to complete our manufacturing facility on a timely basis; and inherent scientific, regulatory and other risks in the drug development and commercialization process. Reimbursement, pricing decisions, the pace of market acceptance, and rate of patient adherence may also affect the potential of BYETTA and/or SYMLIN. These and additional risks and uncertainties are described more fully in the Company's recently filed Form 10-Q. Amylin disclaims any obligation to update these forward-looking statements. 2 Agenda • Introduction > Daniel Bradbury, President & CEO • Highlights from Clinical Trials > Steven Smith, MD, Professor; Assistant Executive Director of Clinical Research, Pennington Biomedical Research Center • Closing Remarks > Daniel Bradbury, President & CEO • Q&A 3 Driving Growth, Building Value NearNear TermTerm MidMid TermTerm LongLong TermTerm • BYETTA and SYMLIN • Exenatide once weekly: • Obesity program address unmet needs potential to transform harnesses natural in diabetes treatment – diabetes treatment hormone synergies glucose control and paradigm > Initiated Phase 2B dose- weight loss ranging clinical study of • Investing for diabetes pramlintide/metreleptin • Opportunities to market leadership combination after positive increase BYETTA proof-of-concept study prescription volume in the large primary • Peptide-focused care segment discovery platform > Field force expansion and optimization • SymlinPen launched 4 Amylin at ADA > Oral presentations, posters, and scientific sessions – BYETTA – SYMLIN – Exenatide once weekly – Obesity programs > Educational symposia grant support > Commercial exhibit – SYMLIN and BYETTA > Interactions with leading researchers and clinicians 5 Diabetes and Obesity Pandemic DiabetesDiabetes PrevalencePrevalence ObesityObesity PrevalencePrevalence No Data <5% 5%–6% No Data <10% 10%–14% 15%–19% 6%–7% 7%–8% >8% 20%–24% 25%–29% ≥30% Source: CDC BRFSS 2005 6 BMI 30 kg/m2 (~ 30 lbs. overweight for 5’ 4” person) Selected Outcome Studies in Type 2 Diabetes Targeting Glycemia, Blood Pressure and Lipids BloodBlood GlycemiaGlycemia LipidsLipids PressurePressure UKPDSUKPDS 9 9 ADVANCEADVANCE 9 9 ACCORDACCORD 9 99 VADTVADT 9 ACCORD Findings • “The findings of higher mortality in the intensive-therapy group led to a discontinuation of intensive therapy after a mean of 3.5 years of follow-up.” > New England Journal of Medicine, June 12 2008 StandardStandard IntensiveIntensive A1CA1C 7.5% 6.4% WeightWeight GainGain 0.9 lbs 7.7 lbs HypoglycemiaHypoglycemia 1.0% 3.1% InsulinInsulin UseUse 55.4% 77.3% 28%28% ofof patientspatients inin thethe intensiveintensive treatmenttreatment groupgroup gainedgained >20>20 lbslbs Improved Glucose Control Comes at a Cost: Weight Gain BloodBlood SugarSugar LevelsLevels (A1C)(A1C) WeightWeight (kg)(kg) 9 7 Conventional Therapy 6 Intensive Therapy 8 5 Intensive Therapy 4 7 3 Conventional Therapy 2 6 1 5 0 Pre- 0 1 2 3 4 5 6 7 8 9 101112131415 Pre- 0 1 2 3 4 5 6 7 8 9 101112131415 Rand- Rand- omization Years omization Years 9 Source: UKPDS study BYETTA and SYMLIN Redefine Diabetes Treatment Weight Loss GlucoseGlucose DPP4 DPP4 MetforminMetformin Lowering InhibitorInhibitor Lowering EffectEffect Sulfonylurea TZDTZD InsulinInsulin Weight Gain 10 Pramlintide, Exenatide and Amylin Obesity Development Program Clinical Update Steven Smith, MD Professor Assistant Executive Director of Clinical Research Pennington Biomedical Research Center Baton Rouge, Louisiana 11 PramlintidePramlintide ++ BasalBasal InsulinInsulin SafelySafely ImprovedImproved GlycemicGlycemic ControlControl WithWith WeightWeight LossLoss -0.0 Placebo (n = 106) 250 Pramlintide (n = 105) 225 -0.2 A1C 200 Δ -0.4 175 * * (mg/dL) 150 * -0.6 Mean (SE) Mean From Baseline (%) From Baseline 125 Baseline Week16 -0.8 Mean (SE) Blood Glucose 100 ** 1.5 Brk Lun Din Bed 1.0 0.5 > Incidence of hypoglycemia 0.0 Body Weight > Pramlintide + Basal insulin: 44% Δ -0.5 -2.3 ± 0.4 kg > Placebo + Basal insulin: 47% -1.0 * * > Severe hypoglycemia: 1 event in pramlintide From Baseline (kg) From Baseline -1.5 group (unrelated to treatment) * * Mean (SE) Mean -2.0 * 0 4 8 12 16 Time (Weeks) ITT LOCF N = 211, * p<0.0001, **p<0.05 Riddle, M.
