Frequently Asked Questions
What is a clinical trial?
What are early phase clinical trials?
Clinical Trials are divided into 4 phases. Phase 1 and 2 trials constitute early phase trials, Phase 3 and 4 research studies are late-phase trials.
The primary objective of Phase 1 studies is to determine the correct drug dosage by evaluating drug safety and determining if there are any side effects. Phase 1 trials are conducted in healthy volunteers.
Phase 2 studies also study the safety of a drug but focus on evaluating its effectiveness. These studies can be conducted in healthy volunteers or in individuals who have a certain disease or condition.
