William Harvey17th century physician who discovered blood circulation: “Nature is nowhere accustomed more openly to display her secret mysteries than in cases where she shows traces of her workings apart from the beaten path; nor is there any better way to advance the proper practice of medicine than to give our minds to the discovery of the usual law of Nature by careful investigation of cases of rare forms of disease.”
Navigating the Web Trying to find specific information can be challenging! Tip- • When wanting to search a specific website, i.e., accelerated approval information found at the FDA.gov website: • Type: accelerated approval site=fda.gov” • Or: regulations site=fda.gov” • Works for any site! site=fda.gov site=hhs.gov

Guidance • They reflect FDA’s current thinking on an issue. • A guidance1refers to any written communication that explains an Agency or Center policy or procedure. The term guidance generally refers to guidance for regulated entities (e.g., the pharmaceutical industry). • However, a guidance document can also be a stand alone document, that is, not tied to any regulation. • Guidances are prepared to establish clarity and consistency in FDA policies, regulatory activities, and inspection and enforcement procedures. 1MaPP 4000.2
Guidance (2) • Guidance documents usually are written to explain specific details of a regulation. • Guidances are intended to assist the pharmaceutical industry in carrying out its obligations under laws and regulations on subjects such as the processing, content, evaluation, and approval of drug product applications and the design, production, manufacturing, and testing of regulated products. • Can use an alternative approach if the approach satisfies the requirements of the applicable statutes and regulations.

FDA Programs to Support Rare Disease Drug Development • FDA Rare Disease Council (New!) • Office of Orphan Products Development (OOPD) • CDER, Office of New Drugs (OND) – Rare Diseases Program (RDP) • CBER rare disease liaison (PDUFA V-coming soon) • CDER, OND - RPM Enrichment and Communications Team (PDUFA V-coming soon) • Office of Special Health Issues (OSHI)
Office of Orphan Products and the Rare Diseases Program- Same? Different? OOPD • Administers Orphan Drug Act • Orphan Designations • Exclusivity • Orphan grants • Device programs • Pediatrics • HUD Humanitarian Use Device designation • Strong advocacy work and outreach with RD stakeholders • RDP • Facilitate communication within CDER/OND review divisions • – Focus on complex regulatory requirements for INDs, NDAs and BLAs • – Develop policy, procedures, and advice for RD clinical development in CDER

Orphan Drug Development • Clinical Investigations are usually conducted under IND • Orphan Drug Act does not define separate regulatory standards for the safety and effectiveness of drugs to treat rare diseases • Requires at least one adequate and well-controlled trial (§314.126) • FDA is required to exercise its scientific judgment to determine the kind and quantity of data and information an applicant is required to provide for a particular drug to meet the statutory standards (§314.105)
For the 20 rare disease products approved in 2011, the number of patients included ranged from less than 20 to 1,266 (median 270) • Most have received Priority Review designation • Breakthrough Therapy designation (new!) • Yet, most of these products are novel ground breaking first-in-disease • Often new clinical endpoints and outcome measures have been developed • The spectrum of rare diseases is incredibly diverse and complex
Meeting Types • Type A – immediately necessary for an otherwise stalled drug development program to proceed • Clinical Holds • Special Protocol Assessments • Dispute resolutions • Timeline, goals • Response in 14 Days • Meeting in 30 Days (or within 14 days of requested date if beyond 30 days)
Meeting Types (2) • Type B (milestone) • Pre-IND (21 CFR 312.82) • Certain End of Phase 1 (21 CFR 312.82) • End of Phase 2 (21 CFR 312.47) • Pre-NDA/BLA (21 CFR 312.47) • Timeline, goals • Response in 21 Days • Meeting in 60 Days (or within 14 days of requested date if beyond 60 days) • Meeting package due 1 month prior to meeting
Meeting Types (3) • Type C (Everything else) • General advice • Under PDUFA V, a sponsor can request, or FDA can decide, for the questions to be addressed in a written response in lieu of a formal meeting • Timeline, goals • Response in 21 Days • Meeting in 75 Days (or within 14 days of requested date if beyond 75 days)
FDASIA Impact on Meetings • Type A meeting requests must include the meeting package • Pre-IND and Type C meetings can be addressed by ‘written response only’ (WRO) • Upon applicant request (grant/deny as usual) or FDA discretion • Meeting package is due at least 1 month in advance of response goal date • FDA response to questions issued within respective meeting goals (e.g., 60 days or 75 days)
Statistics • Last year CDER received approximately 2,000 requests for meetings • Meeting workload varies widely between review divisions, (60 on the low end and 160 on the high end) †Source: FY 2011 Performance Report to the President and Congress for the Prescription Drug User Fee Act
Tips for Productive Meetings • Give your project manager a heads up before submitting a new request • Limit the number of questions to a reasonable number • Yes, subparts of a question are additional questions… • Ask clear questions to help focus answers • Keep most questions applicable to your current state of development • But, keep overall clinical plan in mind
Tips for Productive Meetings (2) • Talk with your Project Manager, set an agenda • Arrive 15-30 minutes early to allow time to check in • Minimize presentations • Ensure you are getting what you need from the meeting • Summarize what you think you’ve heard

Drug Development Recommendations: 1-4 1. Contact the FDA early and avail yourself of all opportunities for meetings and communication 2. Map out your clinical development program as early as possible 3. Don’t overlook value of early phase trials -Animal models -Exploratory endpoints -PK/PD parameters -Surrogates, biomarkers, clinical outcome measures 4. For pivotal study recommend submitting a Special Protocol Assessment (SPA)
Drug Development Recommendations: 5-6 5. Rigorously control study conduct -Make the most of available information -Study personnel training and comprehensive study manual decrease variability in study-related procedures -Possible advantage for smaller trials/rare diseases, i.e., fewer sites, specialized investigators, better inter-site quality control 6. For rare diseases, recommend conducting a natural history study -Can inform many aspects of your development program -Can be retrospective or prospective -Published literature (i.e., case reports) often inaccurate for rare diseases – severe end of disease spectrum tends to get published and may not be representative of broader affected population and/or attenuated presentations
Drug Development Recommendations: 7-9 7. Respect the vulnerability of patients: -Crucial to engage the patient community -Consider an independent Data Safety Monitoring Board or other oversight committee 8. Drug will only be labeled for populations/indications studied – consider early-on -target population (e.g., pediatrics) -likely use 9. For biologics: discuss characterization, assay, antibody testing, etc. with CMC as early as possible
