Vocabulary
Phases of Clinical Trials
Placebo-Controlled: Refers to trials where the effect of a drug is tested against a placebo.
Randomized Controlled Trial (RCT): A study in which participants are randomly assigned to either the treatment or control group.
Ethical Considerations
Informed Consent: The process by which participants are fully educated about the trial’s risks and benefits before agreeing to partake.
Beneficence: The ethical principle of doing good and avoiding harm to participants. Regulatory Frameworks
Good Clinical Practice (GCP): International standards for the design, conduct, performance, monitoring, auditing, recording, analysis, and reporting of trials.
Investigational New Drug (IND) Application: A submission to the FDA to begin clinical testing of a new drug. Challenges in Clinical Trial Design
Crossover Design: A type of clinical trial where participants receive a sequence of different treatments.
Endpoint: The primary outcome measure used to determine the effectiveness of a treatment. Patient Recruitment and Retention
Inclusion/Exclusion Criteria: Specific characteristics that determine who can or cannot participate in a study.
Compliance Rate: The percentage of participants who follow the study protocol as required. Data Management and Integrity
Electronic Data Capture (EDC): A system for collecting and managing clinical trial data electronically.
Audit Trail: A chronological record that provides evidence of the sequence of activities or events affecting data quality. Adverse Events and Safety Monitoring
Pharmacovigilance: The science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems.
Serious Adverse Event (SAE): An adverse event that results in death, is life-threatening, requires hospitalization, or causes significant disability. Clinical Trials in Rare Diseases
Orphan Drug Status: A designation for drugs developed to treat rare diseases, providing incentives such as tax credits and market exclusivity.
Small N Population: A term describing the limited number of patients available for trials in rare diseases. Impact of Clinical Trials on Drug Approval
Regulatory Submission: The formal process of submitting trial data to regulatory bodies for drug approval.
Post-Marketing Surveillance: Ongoing monitoring of a drug's performance after it has been approved for market. Innovation in Clinical Trial Methodologies
Adaptive Trial Design: A trial design that allows modifications to the trial procedures (e.g., dosage adjustments) based on interim results.
Real-World Evidence (RWE): Data derived from real-world settings, used to evaluate the effectiveness of treatments outside the controlled environment of clinical trials. Global Collaboration
Multicenter Trial: A clinical trial conducted at several different locations or centers.
International Conference on Harmonisation (ICH): An organization that sets guidelines for the conduct of clinical trials internationally.
Future Trends in Clinical Trials
Personalized Medicine: An approach to medical treatment that considers individual variability in genes, environment, and lifestyle.
Biomarker: A biological molecule that indicates a particular biological state or condition, used for diagnosis or monitoring treatment response.
