Clinical Research FAQ
What is a Clinical Trial?
A clinical trial is a carefully controlled research study involving human volunteers to assess the safety, effectiveness, and potential side effects of new medical interventions like drugs, treatments, or devices. The goal of these trials is to collect vital information that can lead to the development of new therapies or improve current ones. Clinical trials follow a structured process, typically divided into several phases:
Phase I: This initial phase tests a new drug or treatment on a small group of participants (20-100) to evaluate its safety, determine appropriate dosage levels, and identify any side effects.
Phase II: Conducted with a larger group (100-300 participants), this phase assesses how well the treatment works and continues to monitor its safety.
Phase III: Involving a much larger population (1,000-3,000 participants), this phase confirms the treatment’s effectiveness, compares it to existing standard therapies, monitors side effects, and collects additional safety data.
Phase IV: These studies take place after the treatment is approved and available on the market, aiming to gather further information on long-term effectiveness and safety in a broad population.
Clinical trials are performed under strict scientific and ethical standards to ensure the protection of participants’ health and rights. The data generated through these studies are essential for gaining regulatory approval and advancing medical treatments.
