-Population must have serious or life-threatening disease or condition
-No comparable/significant alternate therapy/treatment

15 days
21 CFR Part 312.34
Treatment use of an Investigational new drug
During which phases is a treatment protocol usually made available?
During Phase 3 but if data is compelling, may be available during Phase 2, OR, after all clinical trials have been completed and Sponsor of trials is awaiting/pursuing marketing approval
How long is the waiting period before a treatment IND study can be initiated?
30 days
When will the FDA permit use of an investigational drug in widespread use?
-If the criteria for expanded access are met (benefits outweigh risk, illness is life threatening, or if no other alternative treatments are available)
-If drug is being investigated in a controlled clinical trial under an IND designed to support a marketing application for the expanded use or all clinical trials are completed
What are the steps for withdrawing an IND? (21 CFR Part 312.38)
A sponsor may withdraw an IND at any time without prejudice by:
-Notifying the FDA
-Stopping all studies and notifying the investigators
-Returning all drug to the Sponsor, or destroying all drug as directed by Sponsor

What is the FDA Form 482?
Notice of Inspection
What is 21 CFR Part 50.20 Subpart B?
General requirements for informed consent
What steps must be taken if IND is put on clinical hold? (CFR Part 312.42)
-Proposed study: Subjects may not be given the investigational drug
-Ongoing study: No recruiting of new subjects & subjects receiving investigational drug must discontinue therapy unless specifically permitted by FDA in the interest of patient safety
What are the reasons for clinical hold?
-Exposure of unreasonable/significant risk/injury to subjects
-Unqualified investigators (lack of scientific training/experience)
-Investigator brochure is misleading, erroneous, or incomplete
-IND does not contain sufficient information to assess risk to subjects of proposed studies
Phase 1 Clinical Trials
-Usually 20-80 subjects
-Meant to assess initial safety and efficacy
-Usually single center sites
Phase 2 Clinical Trials
-Usually no more than several hundred subjects
-Multi-centered sites
Phase 3 Clinical Trials
-Confirmation of short-term efficacy and establish long term efficacy
-Establish benefit-risk relationship
-Provide adequate basis for labeling
-Several hundred to several thousand subjects
Phase 4 Clinical Trials
-Post-marketing
-Continue assessing overall therapeutic value
-Size depends on design
When was the Food, Drug, and Cosmetic Act established and why?
1938; to establish the FDA's jurisdiction over cosmetic and medical devices in the US
What year did they amend the Federal Food Drug and Cosmetic act specifically for medical devices?
1976
21 CFR Part 812
Investigational Device Exemption
21 CFR Part 814
Premarket approval of medical devices
Medical device
Device is NOT dependent on chemical action or being metabolized and;
-also must be recognized in official national formulary or US pharmacopoeia
-intended for use in the diagnosis, treatment, mitigation or prevention of disease in man or other animals
What are the clinical development stages for devices?
1.) Pilot study
2.) Pivotal study
3.) Post-market studies
Compared to drugs and biologics, which typically have 1000s of subjects, device studies usually have 100s of subjects
Class I (device)
Lowest risk
--General controls are sufficient to provider reasonable assurance of the safety and effectiveness
Ex. powered wheelchairs, infusion pumps, and surgical drapes
Class II (device)
Moderate risk, usually requires a 510k (pre-market submission made to FDA)
--General controls are insufficient to assure safety and effectiveness
--Special controls include: special labeling requirements, mandatory performance standards, post-market surveillance
Ex. powered wheelchairs, infusion pumps, and surgical drapes
Class III (device)
Highest risk, usually requires a 510k (pre-market submission made to FDA)
-Usually those that support or sustain human life
-Important for preventing impairment of human health
-Present a potential risk of illness or injury
Ex. implant, used in supporting or sustaining human life
Pre-Market Approval (PMA)
Required process of scientific review (usually Class III) to ensure reasonable safety and effectiveness of device
*Must be FDA "approved" or NOT cleared before marketing per 21 CFR Part 814
Pilot studies (device)
-Exploratory
-Includes small numbers of subjects
Pivotal studies (device)
-Determine safety and effectiveness
-Include most of overall subject numbers
Post-market studies
-Design improvement
-Expansion of safety and effectiveness data
-Development of new uses
What are the abbreviated requirements for device studies? (21 CFR Part 812.2[b])
Abbreviated requirements:
-Label device
-Ensure investigators maintain records and make reports
-Obtain IRB approval: significant risk (SR) vs non-significant risk (NSR)
-Informed consent
-Monitoring of studies
-Refrain from promotion
Exemption for investigation of a device: Abbreviated Requirements (21 CFR Part 812.2[c])
Categories of investigations considered to have approved IDE applications, unless FDA has notified sponsor otherwise
-Those in use in accordance with its labeling & in commercial distribution before 5/28/1976
-A diagnostic device if the testing is:
--noninvasive
--does not require invasive sampling of significant risk
--does not introduce energy into subjects, and,
--is not used as a diagnostic procedure without confirmation by another medically established diagnostic product/procedure
-Device undergoing consumer preference testing modification testing, or combo of 2/more devices in commercial distribution
-Device solely for veterinary use or lab animal research [Show Less]
