Study Notes
Overview of Clinical Trials
- Clinical trials are research studies that assess the effects and safety of new interventions on human participants.
- They help determine if interventions improve health outcomes compared to existing therapies or placebos.
Types of Interventions in Clinical Trials
- Various interventions can be studied, including:
- Medications (drugs)
- Medical devices (implants, tools)
- Behavioral therapies (lifestyle changes, counseling)
- Surgical procedures
Data Generated by Clinical Trials
- Clinical trials produce both qualitative and quantitative data, such as:
- Efficacy outcomes (how well the intervention works)
- Safety profiles (adverse effects and side effects)
- Quality of life assessments
- Biomarkers and physiological measurements
Timing of Clinical Trials
- Clinical trials are typically conducted after preclinical testing but before a new intervention is approved for general use.
- They can start at various stages of the research process, including pilot studies for initial safety and dosage assessments.
Health Authority/Ethics Committee Approval
- Approval indicates that a clinical trial has been reviewed and deemed ethical, ensuring participant safety and rights.
- It signifies that the trial adheres to regulatory standards and guidelines protecting participant welfare.
Non-Eligible Interventions
- Not all interventions can be studied in clinical trials; for example:
- Interventions that are illegal or widely recognized as unsafe
- Treatments without substantive scientific basis
Purpose of Approval
- The purpose of health authority/ethics committee approval includes:
- Protecting the rights and safety of participants
- Preventing ethical violations during research
- Ensuring scientific integrity
Initial Enrollment in Pilot Studies
- Investigators usually enroll volunteers or patients in small pilot studies during the early phases of development (Phase I).
- These trials assess safety, tolerability, and pharmacokinetics before large-scale studies.
Significance of Approval
- Receiving health authority/ethics committee approval means compliance with ethical standards and regulatory requirements.
- It is a prerequisite for initiating recruitment and data collection from participants.
