Clinical research involves systematically investigating new medical treatments and therapies through clinical trials on human volunteers. It is vital for advancing medical knowledge, improving patient care, and ensuring safety. Clinical trials progress through four phases from initial safety testing to large-scale effectiveness trials. Researchers must adhere to strict ethical and regulatory guidelines to protect participants and ensure valid results. While challenging, clinical research benefits patients through medical advancements and improved care.

2. Introduction
► Clinical research is the scientific investigation of new medical treatments and
therapies to enhance patient care.
► It involves systematic investigation to understand diseases, treatments, and their
impact on patients.
► Clinical research is vital for several reasons:
► Advancing Medical Knowledge: It expands our understanding of diseases, therapies,
and medical technologies.

care protocols.
► Key Objectives:
► To identify new treatments and therapies.
► To enhance existing medical practices.
► To ensure patient safety and well-being.

3. Introduction
► Patient centric approach :
► Puts patients at the heart of healthcare progress.
► Patient participation shapes future treatments.
► Improves health outcomes through research.
► Collaboration and Innovation:
► Collaborative efforts among healthcare experts.
► Catalyst for medical innovation.
► Ethical Foundations:
► Ethical guidelines protect participant rights.
► Ensure the well-being of those involved.
► Ensures ethical integrity and transparency.

4. Clinical Trials & their phases
► Clinical trials are scientific studies of the safety and efficacy of a new medical drug or
other treatment, conducted on human volunteers.
► Clinical trials are typically divided into four phases, each serving a specific purpose in
the development process.
► Clinical trials consist of four main phases :
► Phase 1
► Phase 2
► Phase 3
► Phase 4
► Clinical trials progress through four phases, from initial safety assessment in Phase 1
to large-scale testing in Phase 3, and finally, ongoing monitoring in Phase 4.

5. Phase 1: Early Safety Evaluation
► Objectives:
Assess safety, dosage and side effects.
► Small Group:
Involves a small number of healthy volunteers or patients (typically 20-80).
For cytotoxic candidates(eg-anti cancer drugs),the phase 1 trials are conducted on
patients)
► Duration:
Several months.
► Outcomes:
Identifies the maximum tolerated dose and initial safety profile.

6. Phase 2: Efficacy and Side Effects
► Objectives:
Evaluate effectiveness and further assess safety.
► Larger Group:
Enrolls a larger group of patients (around 100-300).
► Duration:
Several months to two years.
► Outcomes:
Determines the drug's effectiveness, dosage and side effects.

7. Phase 3: Large-Scale Testing
► Objectives:
Confirm effectiveness, monitor side effects and compare to existing treatments.
► Large-Scale:
Involves a much larger patient population (often thousands).
► Duration:
Several years.
► Outcomes:
Provides robust data on safety and efficacy for regulatory approval.

8. Phase 4: Post-Market Surveillance
► Objectives:
Monitor long-term safety, efficacy, and less common side effects.
► After Approval:
Conducted after regulatory approval and market release.
► Duration:
Ongoing for as long as the drug or treatment is in use.
► Outcomes:
Continuously assesses the treatment's real-world performance.
