  8. Topics Identified in FDA Briefing Document Introduction • Comparison to other marketed ED drugs • Representative ED patient population • Pharmacokinetic variabilty • Clinical relevance of 2 mg • Efficacy in diabetics • Discontinuations in long-term studies • Hemodynamics • Nitrate interaction • Alcohol interaction

  9. Erectile dysfunction is the “inability to attain and/or maintain penile erection sufficient for satisfactory sexual performance” Erectile Dysfunction (ED) Introduction-ED Definition NIH Consensus Development Panel on ImpotenceJAMA 270: 83-90, 1993

  10. Erectile Dysfunction Introduction-ED Epidemiology and Demographics • US National Health and Social Life Survey (NHSLS)-1992 • Probability sample study of sexual behavior in men and women • Demographically representative cohort of 1,410 men, ages 18-59 • Correlated ED to other diagnoses • ED in 10% of men, ages 18-59 Laumann EO, Paik P, Rosen RC. JAMA 1999;281(6): 537-544

  11. Erectile Dysfunction Introduction-ED Epidemiology and Demographics • Massachusetts Male Aging Study (MMAS) – 1987-1989 • Cross-sectional, community-based, random sample survey of 1,300 men, ages 40-70 • Overall ED rate 52% • Complete 10% • Moderate 25% • Minimal 17% • Extrapolation to US: 30 million men with ED • ED correlated with age, health status, emotional function Feldman et al. J. Urology 151: 54-61, 1994.

  12. Age Related Changes in Erectile Status Introduction-ED Massachusetts Male Aging Study (MMAS) % Age Extracted from Feldman et al. J. Urology 151: 54-61, 1994.

  13. Massachusetts Male Aging Study Introduction-ED ED is Associated with: • Age • Diabetes • Hypertension • Heart disease • Medications • Depression • Psychological factors Feldman et al. J. Urology 151: 54-61, 1994. Johannes et al. J. Urology 163: 460-463, 2000.

  14. ED Population Introduction-Uprima Uprima® Studies MMAS1 Duration of ED (mean) 4.8 years Medical Condition (%) Hypertension 31% 33% Coronary Artery Disease (CAD) 16% 16% Hyperlipidemia 16% — Diabetes 16% 9% 1 Johannes et al. J. Urology 163: 460-463, 2000.

  15. Introduction to Apomorphine Introduction-Uprima • USP drug • Used as a pharmacologic agent since 1869 • Over 1,100 literature citations • Therapeutic doses ranged from 0.2 to 1500 mg • Approximately 8,000 patients/subjects treated in clinical trials • Approved in 12 countries for multiple indications, including Parkinson’s Disease • Daily administration • Usual dose 3 to 30 mg, subcutaneously • Dopaminergic properties recognized in 1967 • Central erectogenic effect recognized in the late 1970’s • Activates DA receptors in hypothalamic and limbic neural pathways

  16. Introduction to Uprima® Introduction-Uprima • Formulated to treat erectile dysfunction • Delivered sublingually (SL) • Unique central mechanism of action • Rapid onset of action • Effective for erectile dysfunction (ED) in a wide spectrum of organic and non-organic etiologies and severities

  17. Introduction to Uprima® Introduction-Uprima • Safety • No deaths • No myocardial infarctions (MI) related to study drug • No cerebrovascular accidents (CVAs) related to study drug • No priapism • Nausea was the most frequent adverse event, syncope the most significant

  18. Proposed Indication Uprima® is indicated for thetreatment of erectile dysfunction

  19. Doses Proposed doses: 2, 3 and 4 mgUprima® will be available as a sublingual tablet

  20. Rationale for Uprima® Treatment of ED Introduction-Uprima • ED is associated with a number of diseases and conditions • Drugs with different modes of action are desirable as with other disorders with complex pathophysiology, e.g., hypertension, depression • Current therapies are limited: • No drug is effective in all patients • Each drug has its own unique adverse event profile • The currently approved agents work by peripheral mechanisms • Treatment is strongly influenced by couple and physician choice • New drugs with different mechanisms offer significant potential benefits

  21. Rationale for Uprima® Treatment of ED Introduction-Uprima • Uprima® has a: • Unique central mechanism of action • Novel delivery system • Rapid onset • Uprima® has been studied in 27 clinical trials and has been shown to be a safe and effective treatment for ED in patients with and without known organic diseases

  22. Uprima® Clinical Trials Introduction/Uprima (N = 3,035) • Phase I • Pharmacokinetics • Metabolic fate • Elderly (³65 years) • Renal/Hepatic Impaired • Drug interactions (Zofran®, Compazine®) • Special Phase I/II/III • Antihypertensives and nitrates • Diabetics • Alcohol • Prostatectomy • Spinal cord injury • Phase III • Three controlled crossover • Dose-optimization • One controlled parallel • Five long-term, open-label • One first dose administered at home
