    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.
