Study Notes
General Requirements for FDA Approval
- Demonstrated safety and efficacy of the drug
- Demonstrated process control and validation of the manufacturing process
The Drug Development Process
-
Biological Characterization
- Pharmacodynamics: Investigating the biochemical and physiological effects of a drug
- Toxicology: Investigating the potential for adverse or undesired effects of the drug
-
Clinical Trials
- Phase 1: Focused on determining safety and dosage
- Phase 2: Focused on effectiveness but also short-term safety
- Phase 3: Confirming effectiveness and longer-term safety
-
Preformulation Studies
- Integrated with knowledge gained from ADME studies
- Used for the rational development of stable, safe, and effective dosage forms
Investigational New Drug Application (IND)
- Must be filed with the FDA before human testing
- Defines all aspects including animal studies, manufacturing info, and clinical plan
- Reviewed by experts
- Application is forwarded to a specific division within the FDA
Final Product Development
- During clinical studies, the final formulation is completed as well as the packaging and labeling
New Drug Application (NDA)
- A complete and organized presentation of pre-clinical and clinical data with summaries of human pharmacokinetics, bioavailability, microbiology (for antibiotics), a discussion of the benefits and risks of the drug's usage, and a complete proposed product labeling
- Prior to final approval, the manufacturing facilities must be inspected to assure its capability to comply with quality standards
Post-marketing
- Following approval, the drug product is continually monitored in clinical investigations to learn more about the drug
- Adverse Reaction Reporting from physicians and pharmacists
- Comprehensive annual reports are also required
Variations in the Drug Development Process
Orphan Drugs
- Drug used to treat a rare disease or condition
- FDA response is usually within 60 days
Expanded Access
- To facilitate getting the drugs to these patients outside of a clinical trial
Abbreviated New Drug Application
- NDA for generic drug approval
Supplemental New Drug Application
- For changes in labeling, method of synthesis
Expedited Programs for Serious Conditions
Fast Track
- For a serious condition and nonclinical or clinical data demonstrate the potential to fill an unmet medical need
Breakthrough Therapy
- FDA takes actions to expedite development
