2 Meet with FDA early in process and keep in touch.
NAVIGATING THE FDA Vivian K. Dullien, PhD

3 Before you meet, do your homework.
NAVIGATING THE FDA Vivian K. Dullien, PhD

4 What are you? Diagnostic Device Drug Biologic Combination
NAVIGATING THE FDA Vivian K. Dullien, PhD

5 What disease? NAVIGATING THE FDA Vivian K. Dullien, PhD

6 What for? Screening? Diagnosing? Monitoring? Treating?
NAVIGATING THE FDA Vivian K. Dullien, PhD

7 What patient population?
Screen general population Treat general population Symptomatic High risk Early stage Late stage Age group NAVIGATING THE FDA Vivian K. Dullien, PhD

8 If device or diagnostic, is there a predicate?
Comparison to predicate – where similar, where not NAVIGATING THE FDA Vivian K. Dullien, PhD

9 Devices: 510(k) or PMA? Determine: Risk level Novelty Predicate
Duration: 510(k): 30+ days PMA: 1 year NAVIGATING THE FDA Vivian K. Dullien, PhD

10 The driver in the FDA process – “Indications for Use”
Drug or device? The driver in the FDA process – “Indications for Use” Part of product label NAVIGATING THE FDA Vivian K. Dullien, PhD

11 Examples of Indication for Use
Drug: Nasal spray, 50 mcg is indicated for the treatment of the nasal symptoms of seasonal allergic and perennial allergic rhinitis in adults and pediatric patients 2 years of age or older. “X” nasal spray, 50 mcg is indicated for the prophylaxis of nasal symptoms of seasonal allergic rhinitis in adult and adolescent patients 12 years and older. Diagnostic: “X” culture test is a qualitative in-vitro diagnostic test for the rapid detection of nasal colonization of staphylococcus aureus. The test is intended to aid in the prevention and control of staphylococcus aureus infections in healthcare settings. The test is not intended to diagnose staphylococcus aureus infections, nor monitor treatment of infection. NAVIGATING THE FDA Vivian K. Dullien, PhD

12 Product label can include:
Description (clinical pharmacology) Clinical studies summary Indication and usage Warnings Precautions Adverse reactions Contra indications Dosage and administration Information for patients NAVIGATING THE FDA Vivian K. Dullien, PhD

13 Your FDA studies are to support the claims in your “Indications for Use”
NAVIGATING THE FDA Vivian K. Dullien, PhD

14 “Indications for Use” Will determine what you can say in marketing material once you have been approved NAVIGATING THE FDA Vivian K. Dullien, PhD

15 Study endpoints How will you measure your safety and efficacy?
If device – agreement to predicate – what is your predicate? What is the gold standard? Are you an AID in diagnosing/treating or stand-alone? NAVIGATING THE FDA Vivian K. Dullien, PhD

16 Study endpoints: statistician’s inputs
Study power N size Methods to measure statistical significance NAVIGATING THE FDA Vivian K. Dullien, PhD

17 Survey the market Review similar products on the market
Look at labels, Indications for Use, warnings and limitations NAVIGATING THE FDA Vivian K. Dullien, PhD

18 Ready to approach FDA Phone, e-mail
Set up a face-to-face meeting: pre-IDE or pre-IND Send in information before meeting Include: product description, predicate comparison if applicable, suggestion on how to be classified, indications for use, protocol outline with study endpoints, suggest N size. If drug results of animal study safety, pilot/lab, feasibility results, statistical methods to be used List of questions for FDA Who will attend NAVIGATING THE FDA Vivian K. Dullien, PhD

19 FDA - organizational On Internet (http://www.fda.gov/opacom/7org.html)
Office of the Commissioner: Biologics: Devices and Radiological Health: Drug Evaluation: Veterinary Medicine: Regulatory Affairs: Food Safety and Applied Nutrition: NAVIGATING THE FDA Vivian K. Dullien, PhD

20 FDA meeting & post-meeting process
Get FDA feedback and take minutes Send minutes to FDA for review Incorporate FDA suggestions into your planned studies Send protocol to FDA for review and comments before you start NAVIGATING THE FDA Vivian K. Dullien, PhD

21 Clinical devices: Investigation device exemption (IDE), unless exempt
Need: Protocol approved by IRB. If significant risk, the IDE must be approved by FDA Informed consent from patient Labeling for investigational use only Required records and reports Conduct under GCP (21 CFR 812, 50, 56, 54, 820) NAVIGATING THE FDA Vivian K. Dullien, PhD

22 IDE includes: Device name and description Device intended use
Sponsor contact information Manufacturer information Laboratory studies Reports of animal studies Prior publications Investigational plan, including protocol, risk analysis, monitoring procedures, list of investigators, IRB’s, informed consents Labeling Description of methods, facilities and controls used for manufacture, processing, packing, storage, installation of device NAVIGATING THE FDA Vivian K. Dullien, PhD

23 IDE exempt: Non-invasive
Does not require invasive sampling that presents significant risk Does not introduce energy into a subject Is not used as a diagnostic procedure, without confirmation of another medically established product or procedure NAVIGATING THE FDA Vivian K. Dullien, PhD

24 Phases of device studies
Feasibility Pivotal 510(k) PMA NAVIGATING THE FDA Vivian K. Dullien, PhD

25 Pre-IDE process Informal guidance meeting (before IDE submitted): help with development of protocol, supporting pre-clinical data. Can be telephone conference calls, video conference, or face-to-face Formal guidance meeting: determination meeting – written request to review intended use, protocol, and type of valid scientific evidence required. A pre-IDE submission Agreement meeting – written request to reach agreement with FDA regarding FDA’s review of the clinical protocol and investigational plan NAVIGATING THE FDA Vivian K. Dullien, PhD

26 Detailed description of device
Agreement meeting written request: Detailed description of device Detailed description of proposed conditions of use of device Proposed plan (including clinical protocol) Information regarding expected performance Agreement put in writing Keep in contact with FDA throughout process from informal to formal agreement meetings NAVIGATING THE FDA Vivian K. Dullien, PhD

27 Additional guidances can be found:
Early collaboration meetings Goals and initiatives for the IDE program Pre-IDE program: “Issues and Answers” Search Internet and find guidances. FDA has put guidances on the Internet for devices and drugs NAVIGATING THE FDA Vivian K. Dullien, PhD

28 Drug review steps Pre-IND, animal testing
IND – outlines human testing. Meet with FDA before submitting IND. IND reviewed by FDA and IRB Phase 1: subjects Phase 2: subjects Phase 3: several hundred to Meet with FDA before Phase 3 Pre-NDA, meet with FDA before submitting NDA Submit NDA Review Facilities inspected Approvable or not approvable NAVIGATING THE FDA Vivian K. Dullien, PhD

29 Pre-clinical testing in animals
Assessing toxicity in single doses of increasing strength, 2+ species Different routes of administration Determine ED50, LD50, duration of effects Subjects autopsied for cause of death Sub-acute toxicity 3 or more routes of administration 3 different dose levels, 2+ species, observed 2 – 12 weeks Estimate what human dosages will be Especially note liver, kidneys and nervous system Chronic toxicity 3 – 24 months At least 6 months before human studies Carcinogenic effects, 6 months, 2+ species, same route of administration as humans Teratogenic effects NAVIGATING THE FDA Vivian K. Dullien, PhD

30 IND contents include: Pre-clinical toxicology and pharmacology results
Phase 1 protocols Drug facilities, processes, articles used in manufacturing, processing, packaging, and storing drugs for humans Chemistry, manufacturing and control information Previous experience with human subjects NAVIGATING THE FDA Vivian K. Dullien, PhD

31 Drug clinical stages Phase 1 - healthy volunteers
- Side effects, how drug is metabolized and excreted - Safety Phase Patients - Effectiveness – preliminary information if drug works in humans with the disease Phase large safety and efficacy studies - different dosages, drug combinations and populations NAVIGATING THE FDA Vivian K. Dullien, PhD

32 Timelines – clinical testing of drugs
Range: 2 – 10 years (average 5 – 7 years) Phase years Phase years Phase years NDA usually 100,000 pages in length, takes at least 6 months to review. Average 2 years (range 2 months to 7 years.) NAVIGATING THE FDA Vivian K. Dullien, PhD

33 Quality of clinical data
IRB approval, informed consent Study conducted according to protocol adverse events recorded subsets met the inclusion/exclusion criteria NAVIGATING THE FDA Vivian K. Dullien, PhD

34 Reviewing applications for drug or device
FDA review team - medical doctors, chemists, statisticians, microbiologists, pharmacologists and other experts - determine if drug/device is safe and effective for its proposed use Each reviewer prepares written evaluations that are considered by team leaders, division directors, office directors, depending on type of application Sometimes FDA calls upon advisory committees NAVIGATING THE FDA Vivian K. Dullien, PhD

35 Issues that can arise Clinical data not supportive of indications for use – need more data Inadequacy on how people respond to various dosages – need more data “Approvable” – probably be approved, provided certain issues get resolved Labeling Safety issues Manufacturing issues – can delay or deny application. Product that is going to be marketed is the same product that was tested Depending on FDA action – meet to discuss deficiencies, ask for hearing, correct deficiencies, submit new information or withdraw application NAVIGATING THE FDA Vivian K. Dullien, PhD

36 Device or drug Continuous interaction between FDA and company during review process NAVIGATING THE FDA Vivian K. Dullien, PhD
