Tuberous Sclerosis : Rare Autosomal Dominant Genetic Disease • Estimated to be 1 in 6,000 live births • 1-2 million worldwide (50,000 US) • All sexes, races, and ethnicities • Benign tumors (hamartomas) interfering with organ function • Common sites are skin, kidney, brain, lung, eyes, and heart • Skin lesions including facial angiofibromas in >90% of patients • Neurologic manifestations are predominant clinical feature • Epilepsy in 70-80% due to cortical tubers • SEGAs (subependymal giant cell astrocytoma) in 5-20%; associated with hydrocephalus and increased intracranial pressure Figure from Krueger and Franz.

Orphan Drugs: Recent Trends in approvals • During the 2000s, orphan products comprised 22% of all NMEs and 31% of all SBs receiving US marketing approval • The number of orphan product designations increased from 208 in 2000-02 to 425 in 2006-08 • Novartis has 39 orphan designations and 18 orphan approvals to date
Orphan Drug Approvals 2009 BioMarket Trends: Jun 15 2010 (Vol. 30, No. 12)
Orphan Drug Legislation • The US Orphan Drug Act has been a success in encouraging many new drug approvals for rare diseases • More than 2100 orphan designations • Designations more than doubled during past decade • Over 350 approvals for orphan products • Similar orphan drug legislation (ODL) in other countries (EU, Japan, Australia) • But, only ~200 of > 6000 rare diseases have an approved Rx • Additional “Push” and “pull” incentives could foster greater investment in rare (and neglected) diseases
Mechanisms to spur innovation for Orphan Diseases • “Push” mechanisms • Increase grant and research funding • Stronger partnership among key stakeholders (HA, industry, academia, advocacy groups), including “de-risking” programs • Increase and expand R&D tax credit to neglected diseases • “Pull” mechanisms • Extend market exclusivity (10 years) and include neglected diseases (clearly defined) • Favorable reimbursement approach – automatic • For NMEs, consider patent extension on the molecule (e.g. 6 mo similar to pediatrics) • Advance market commitments (AMCs) – subsidize purchase of product after development • Priority review voucher system (PRV) – expand and improve
Opportunities and Incentives for Orphan Drugs and Neglected Diseases: Regulatory Flexibility • Apply existing regulations with greater flexibility to foster development (accelerated approval program) • Reduced requirements for clinical and preclinical program, including smaller trials and safety databases, historical controls, retrospective analyses , observational data, etc. – establish global standards (ICH) • Consider acceptance of biomarkers (e.g. PD endpoints) as surrogates for approval (reduced burden for qualification) • Conditional approval for rare & neglected diseases • Global harmonization of regulatory requirements • Partner with WHO and other health authorities – leverage expertise
