Clinical trials
Trials phases:
- Phase-1
- Phase-2
- Phase-3
- Phase-4
Phase-1: Clinical trials
healthy people of about 20-30 are selected and the drug is administered to them to check the working and possible side effects the drug might have on the patients.
Phasee 2 clinical trial:
Around 100-300 people are used in this phase. This phase works more on the effectiveness of the drug. The aim is to obtain data on whether the drug is effective in diagnosing certain conditions in people or not. It continues working on safety even in this phase but is mostly restricted to checking out on the side effects that the drug might have on the patient.
phase 3 clinical trial:
The number of subjects is usually about 1000-3000 in this phase. It continues studying the safety and effectiveness of the drug but only this time with different populations and dosages. If the drug is approved by the concerned authorities or organization (FDA) after seeing the positive trial results, it proceeds to the final phase.
Phase 4 clinical trial:
After getting approval from the FDA the drug is checked on diverse populations for safety and effectiveness.
