The Pipeline
FDAFDA• FDA regulations found in Title 21, Code of
Federal Regulations – 21 CFR• Regulate products• Coverage includes – but not limited to:
– Nonclinical studies– Clinical studies– Human Subject Protection– Institutional Review Boards (IRBs)– Manufacturing– Labeling– Post-market adverse event reporting
FDAFDA
• FDA regulations “speak” to: – Importers/exporters– Study sponsors– Nonclinical laboratory personnel– Clinical investigators– IRBs – Medical product users – hospitals, clinics,
nursing homes, individual practitioners
Pharmaceuticals versus devicesPharmaceuticals versus devices
• Pharmaceuticals (drugs and biologics) are covered by different FDA regulations from those covering devices, though some regulations are shared
• Many differences result from differences among the products themselves
Nature of productNature of product
Pharmaceuticals Pharmaceuticals (drugs & biologics)(drugs & biologics)
• Molecular entities• Limited shelf life• Long market life• Potential for
interactions with other drugs
• Wrong drug/dose issues
DevicesDevices• Complex components• Many = durable
equipment• Short product cycles
– “tweaking” of design• Device malfunctions• User errors
Nature of firmsNature of firms
DevicesDevices• Entrepreneurial firms
common• Device “developer”
often involved• Many have minimal
clinical trial experience
• Sponsor-investigators common
PharmaceuticalsPharmaceuticals• Large, often multi-
national firms• Extensive clinical trial
experience
StudiesStudies
DevicesDevices• Nonclinical
– biocompatibility – nonclinical studies may suffice
• Clinical – subject populations usually 100s – pilot study possible + pivotal– blinding less common– “controls” vary– CI training often critical (Human
Factor concerns)
PharmaceuticalsPharmaceuticals• Nonclinical
– toxicology
• Clinical – subject populations
commonly 1000s– phases– routinely blinded– placebo = common control

including obtaining and maintaining IRB approval and obtaining subject informed consent
– Follow the approved investigational plan/protocol

Regulatory distinctions -1Regulatory distinctions -1PharmaceuticalsPharmaceuticals• Adequate, well-controlled
trials• CROs – 312.52 = transfer
of regulatory obligations• Form FDA 1572• FDA agreement not usually
required before enacting studies changes
• AE reports during study may use Form 3500A (Med Watch) – 312.32(c)(B)
DevicesDevices• Valid scientific evidence• CROs – regulations silent
save for definition of monitor [812.3(j)]
• Investigator agreement [812.43(c)]
• Significant study changes require IDE supplement approval
• AE reports during study notnot to go to MedWatch (i.e., not use MDR)
Regulatory distinctions -2Regulatory distinctions -2
PharmaceuticalsPharmaceuticals• Manufacturing –
cGMPs – Parts 210 & 211 + Part 606 for blood & blood products
• MedWatch reports for approved pharmaceuticals are voluntary
DevicesDevices• Manufacturing – Part
820 (QSR)• MDRs for approved
devices are mandatory – Part 803
Additional Device Distinctions -1Additional Device Distinctions -1
• Classes of Devices – risk-based
determination
– 21 CFR 860 – classification procedures
– 21 CFR 862 through 892 – specific device
classifications by product type
Additional Device Distinctions -2Additional Device Distinctions -2
• Cleared devices – 510(k) – 21 CFR 807, subpart E – Premarket
Notification Procedures– “substantially equivalent”
• Approved devices– 21 CFR Part 814 – PMA, PDP, HDE– Safety and effectiveness – PMA & PDP– Safety – HDE
Additional Device Distinctions -3Additional Device Distinctions -3
• Significant risk/non-significant risk studies
• Exempt studies/in vitro diagnostics (IVDs)
• Protocol changes and 5-day notices
Significant Risk (SR)Significant Risk (SR)• Regulatory definition (21 CFR 812.3(m)) – device
that presents potential for serious risk to health, safety, or welfare of a subject, particularly if it
• Is intended as an implant
• Is purported or represented for use in supporting or sustaining life
• Is for a use of substantial importance in diagnosing, curing, mitigating, or treating disease, or otherwise preventing impairment of human health
Non-Significant Risk (NSR)Non-Significant Risk (NSR)
• Decision based on use of device in study• Sponsor makes initial assessment• IRB makes determination• FDA can disagree• If NSR study, no IDE application to FDA• Informed consent required• Abbreviated requirements apply (21 CFR
812.2(b))• Considered to have an IDE
In Vitro Diagnostics (IVDs)In Vitro Diagnostics (IVDs)
• SR/NSR/exempt studies
• Exempt if:• labeled according to 21 CFR 809.10
• noninvasive
• noninvasive sampling or no significant risk
• does not introduce energy into a subject
• not used as the diagnostic for determination of treatment
Significant Risk IVD StudiesSignificant Risk IVD Studies
• If study involves invasive sampling that presents a significant risk
• If results from use of an investigational IVD will determine treatment, could inaccurate results:
- be life-threatening- result in permanent functional impairment- result in permanent structural damage- necessitate medical or surgical intervention
to prevent impairment or damage
Clinical Investigators Clinical Investigators • Compliance inspection program covers
study specific inspections and audits of CIs (physicians, veterinarians, others) conducting clinical trials on human and veterinary products
• Usually preannounced• Inspection includes an interview with the
clinical investigator and pertinent study staff + an in-depth study/data audit – to validate study findings and verify compliance with regulations
