Have you ever wondered how new medications and treatments are developed and tested? The process is thorough and methodical, ensuring that the new medicines or treatment options are safe for the patients.

 Clinical trials are the process of testing new medicines. They are conducted worldwide, and the majority of the medicines that are publicly available are tested through them. These trials are large and conducted in various phases. If you want to know more about the various phases of clinical trials, you are at the right place.

#1 – First Phase

The first phase is very small and usually starts with less than a few hundred people. The main goal of the first phase is to understand how the medications interact with the human body. Researchers administer very low drug doses to gather preliminary data on its safety. This helps the researchers determine how much dose is enough and whether there are any side effects of the medicine. If there are none, they proceed to the next phase.

#2 – Second Phase

Once phase one is completed, the researchers move to the second phase. In this phase, they assess the safety and efficacy of the medicines. As the side effects and ideal dosage are figured in the first phase, the second phase focuses on the efficacy. The researchers monitor the health vitals of the participants and then check if the medicine is working as they want it to. Once confirmed, they move to the next phase.

#3 – Third Phase

This is the biggest part of the trial, as it involves several hundred to several thousand participants. The primary goal of this phase is to confirm the efficacy, safety, and wide-range administration of the medicines. This is quite an important part, as the previous phases had fewer people. With the huge number of participants, reliable data on the trials are obtained.

#4 – Final Phase

The final and fourth phase is nothing but the waiting game. In this phase, the researchers take care of the data collection, management, and submission to the regulatory authorities. In this phase, the researchers ask for approval from the regulatory authorities and just have to wait until approval.

Final Words

Clinical Trials are paving the way for new medicines to enter the markets. The researchers do a lot of hard work in conducting these trials, and these phases make it easier to perform them.
