33 Clinical Relevance of Treatment Effects Leonard R. DeRogatis, PhD Director Johns Hopkins Center for Sexual Health and Medicine C1C
34
34 Clinical Relevance of Treatment Effects Evidence from Phase III Study All endpoints derived from concerns and experiences of HSDD patients Decrease in personal distress is a direct marker of relevant treatment impact Improvement of sexual function across all relevant domains Evidence from Clinical Relevance Study C2C
35
35 Anchoring Technique for Examining Clinical Relevance Well-established through broad use Readily understood Patient-based. Uses direct questions concerning patient benefit Patient perceptions of benefit are tied to study endpoints through statistical analyses (ROC) Results define meaningful change (MCID) which helps establish clinical relevance C3C

109 Conclusion HSDD has a significant impact on women’s lives Intrinsa presents a meaningful treatment option for women with HSDD, since it improves sexual desire and activity, and reduces distress Intrinsa offers an important treatment option for physicians who have no approved therapies for HSDD D20C

112
112 No Safety Signals Observed in Intrinsa Trials Phase II/III Studies found no safety signal 18 months in SM women 12 months in NM women LT2C
113
113 Phase IV Safety Study Options Observational studies Randomized controlled trials (RCTs) Patient registries LT3C
114
114 Observational Studies Advantages Ideal for rapid signal detection Real world setting Large numbers of patients Ability to adjust for confounding variables Evaluate all patients exposed to Intrinsa LT4C
115
115 FDA Feedback Issues raised by FDA Inability to capture medical claims data on women over 65 Inadequate statistical power to detect possible safety signal P&G response Women over 65 represent 2% to 3% of potential Intrinsa users Study will have adequate power LT5C
116
116 Ingenix ® LabRx Comprehensive longitudinal database Hospital, physician, pharmacy, laboratory Open formulary (United Healthcare) Validation of endpoints (85% abstraction rate) Timely claims processing (90% within 4 mos) Stable patient population (85% retention/yr) Experienced research staff Proven track record LT6C
117
117 Examples of Analysis Based on Ingenix Data at 2 Years Post-launch FDA-accepted protocols for cardiovascular outcomes in: Oral contraceptive users Oral anti-diabetic therapies Other outcomes in current, FDA-accepted Ingenix ® postmarketing safety studies Allergic reactions Vascular insufficiency of the intestine GI surgery Pregnancy and pregnancy outcome LT7C
118
118 Intrinsa Observational Study Objective: Compare event rates in Intrinsa users vs nonusers Design: Prospective cohort with 3:1 matching over a 5 year duration Exclusion criteria: None Endpoints: Cardiovascular disease (CVD) CHD (fatal, nonfatal MI) Stroke (fatal, nonfatal) Venous thromboembolic disease (DVT, PE) Composite CVD endpoint Breast cancer LT8C

122
122 Robustness of Observational Study Collaborative protocol development External experts and FDA Blinded medical expert panel will adjudicate endpoints Independent safety review board will analyze, interpret and report results to FDA and P&GP First data at 18 months post-launch LT12C
123
123 Phase IV Safety Study Options Observational studies Randomized controlled trials (RCTs) Patient registries LT13C
124
124 Randomized Controlled Trial Option Advantages Ideal for hypothesis testing and determination of cause/effect Random allocation minimizes confounding Disadvantages Not real world (i.e., inclusion/exclusion criteria) Recruitment and retention Timeliness LT14C
125
125 Patient Registry Option Advantages Signal detection Large number of exposed patients Real world setting Recruitment ease Disadvantages No comparison group LT15C
126
126 Summary P&GP is committed to continued monitoring of long-term safety of Intrinsa Ingenix ® LabRx is one of the largest and most comprehensive insurance claims databases Novel approach Implementation at launch External expert design Independent safety review board execute, analyze and report to FDA Optimal study design for timely signal detection LT16C

129 1) Do the efficacy data represent a clinically meaningful benefit? Yes We assessed three related, but independent endpoints Efficacy assessments were patient-centered The results were statistically significant and highly consistent across all studies and endpoints The randomized withdrawal trial reinforced the pharmacologic effect of the drug
130
130 2) Is the patient exposure adequate to demonstrate long-term safety? Yes Number of Patients Surgical Menopause Natural Menopause Total Exposure ICH Guideline Minimum ≥ 300 mcg/day 300 mcg/day At least 1 dose12885171805 ≈ 6 months9573881345300-600 ≈ 12 months494136630100 ≈ 18 months1270 Total patient months 10742335014092
131
131 3) Are there safety concerns or unanswered questions that need to be studied? It is not uncommon to have unanswered questions at approval Points to consider: No safety signals have been seen Androgens and estrogens have been used for years in women We have proposed a rigorous independent post- marketing safety study to supplement traditional PV Labeling will reflect current knowledge
132
132 4) Are the efficacy and safety data adequate to support approval of TTS? Yes
