Phase II Results Demonstrate Long- and Short-Term Efficacy of Delamanid
Short-Term Efficacy— As reported in the New England Journal of Medicine (NEJM), results from Trial 204 demonstrate
treatment with delamanid + OBR led to 53% increase in SCC compared to placebo + OBR
— If SCC achieved within first 2 months, patients have considerably higher likelihood of successful treatment outcome
Long-Term Efficacy— As reported in the European Respiratory Journal (ERJ), combined analysis of Trials
204/208/116 shows
— Among all patients (N=421) 74.5% achieve favorable outcome with DLM >6mo delamanid vs. 55.0% with <2mo (1% mortality in patients receiving DLM ≥ 6mo vs. 8.3% ≤ 2mo)
— Among all patients (N=421) 1% mortality in patients receiving DLM ≥ 6mo vs. 8.3% ≤ 2mo

Safety Results Demonstrate Delamanid was Well-Tolerated Among Study Subjects
— Most AEs within mild to moderate range and balanced among delamanid and placebo groups; consistent with OBR
— Higher incidence of QTcF prolongation, which did not result in any clinical manifestations
— As reported at International AIDS and ICAAC 2012 Conferences, DDI studies in healthy subjects show no significant interactions when delamanid co-administered with tenofavir, efavirenz or Kaletra

Committed to the Rational Use of Delamanid – Responsible Access Plan (RAP)
Professional Education— Medical education program targeting physicians and patients
— Focus topics such as diagnostic options, timely and accurate SAW reporting, background on development of drug resistance, among others
Comprehensive Registry—A multi-center, EU-wide post-authorization study to assess the safety and drug usage of Delamanid in MDR-TB patientsStrict Distribution Control— All orders routed through single distributor using web-based tool

Otsuka’s Commitment to Improving Patient Care
— Support and/or develop approaches to excellence in TB case management (Moldova)
— Explore models of patient support leading to individual and community socio-economic improvement
— Advocate for sustained international commitment and response to the TB crisis from funders and policymakers
— Increase public awareness of TB as a universal health issue

Making an Impact – One Patient at a Time
Mildred Fernando— Battled TB for a total of 10 years,
since age 19
— Diagnosed twice with XDR-TB, received two, 18 month courses of treatment
— Father died of TB, two sisters diagnosed and survived
— Mildred participated in delamanid RCT and open-label study
— Today she is living TB-free and works at the Lung Center of the Philippines, helping other TB patients. She is also a strong patient-advocate for the WHO and other international organizations

Otsuka’s Commitment to TB Education, Awareness & Advocacy
− To capture stories like Mildred’s, photo magazine created with TB/MDR-TB life stories (Estonia, Philippines, Peru)
− Collaboration with European Respiratory Society (ERS)
− Aimed at illustrating MDR-TB as a potentially treatable and winnable disease, providing hope and encouragement to other patients

Conclusion
— Global TB Program a long-term investment by Otsuka
— New compound represents only a first step in a comprehensive disease management package that aims to FighTBack against TB from all angles (diagnostics, pediatrics, public health, etc.)
— Actively working with global TB stakeholders and other third-parties with mutual goals of addressing unmet medical needs in TB while promoting rational use of new compounds and minimizing resistance
