What are the 4 stages of clinical trials?
Phases of Clinical Trials
- Phase 1 Clinical Trial. The purpose of Phase 1 is to ensure that the treatment is safe in humans and to determine how and where it distributes within the body.
- Phase 2 Clinical Trial.
- Phase 3 Clinical Trial.
- Monitoring Post-FDA Approval.
What is pivotal role?

Why are pivotal clinical trials so important?
Why are pivotal clinical trials important? Pivotal clinical trials (also known as “registration studies”) are very important because their results will be evaluated by regulatory authorities to decide whether or not a drug shows the safety and efficacy required to be approved and commercialized.
What is a medical device pivotal study?
A medical device pivotal study is a definitive study in which evidence is gathered to support the safety and effectiveness evaluation of the medical device for its intended use. Evidence from
How many patients should be recruited for a pivotal trial?
The number of patients (sample size) to be recruited in a pivotal trial may vary a lot across different therapeutic areas. In sarcoma clinical trials, for instance, typical sample sizes of pivotal studies may be in the range of 350-500 participants. In other diseases, a pivotal trial can include more than 1,000 patients.
