  1. Genetic Diseases of Children The Role of Orphan Drugs Marlene E. Haffner, MD, MPH 9 March 2011 mhaffner3@verizon.net 301 984 5729

  2. First let’s talk about drug development • Complex and failure prone process • Takes 5 – 10 years or more • Human genome opening many doors • Many if not most genetic diseases of children are orphan diseases – prevalence of rare disease is less than 200,000 in the US by law

  3. New Drug Development IND NDA Drug Discovery Animal Testing Post Marketing Human Testing Approval Phase I Phase II Phase III Preclinical Development 0.5 - 3 years 0.5 - 1 year 2 - 5 years 6 months - 1 year 4 - 10 years $1.2 Billion

  4. Orphan Drug Act • Amended the FD & C Act – signed in 1983 • Has been very successful – almost 400 new drugs developed since signing • Many more in the pipeline • Children recognized • Incentives in the ODA to offset cost of development for sponsors

  5. Characteristics of a Rare Disease • While < 200,000 by law, many if not most < 6000 patients in the US • Many Genetic Diseases – often heterogeneous • ~ 85% Serious or Life Threatening • Children comprise ~ 50% • Most are chronic

  6. Development of orphan products • Same as for non-orphan products • Orphan products need to be as safe and as effective as non-orphan products • Always must evaluate risk vs benefit • Much attention given to Orphan Products in the FDA

  7. In the realm of Genetic Diseases of Children • PKU - Kuvan • NAGS disease – Carbaglu • Urea Cycle Disorders – Buphenyl and Ammonol • SCID (ADA type) – Adagen • Tyrosinemia – Orfadin WOULD NOT HAVE BEEN DEVELOPED WITHOUT THE ORPHAN DRUG ACT INCENTIVES

  8. Many treatments, no cures • Cystic Fibrosis - many products to alleviate disease • Sickle Cell Disease – several alleviating treatments but no definitive therapy • Human Genome project and aftermath leading to more directed products • No Stem cell therapies yet • Lives have been significantly and positively altered
