What is a Clinical Trial?

Rare diseases are very hard to treat, and few treatment options are available. People suffer a lot from diseases like Cancer, HIV or other genetic conditions. The researchers are always working to develop new medicines to combat such diseases. That’s why they perform clinical trials to test the new medicines or the treatment options.

Numerous clinical trials are running worldwide for a wide range of medicines. If you are curious about clinical trials , then you are at the right place. In this post, we will discuss them.

A clinical trial is an experiment in which researchers perform tests on humans. These tests are meant to confirm the safety and efficacy of groundbreaking medicines that help humanity.

Phases of Clinical Trials

Every clinical trial is divided into multiple phases to make it easy to conduct the trials. Here are the phases of clinical trials.

#1 – First Phase

The first phase begins the trial. The main aim of this phase is to recruit the participants and test the medicines on them. As this is the first stage, the researchers recruit only a few participants. This helps them understand the safety of the medicines with a small number of participants. After that, the researchers move to the next phase.

#2 – Second Phase

The second phase can have more participants. As the researchers have identified the safety of the medicine or treatment methodology in the first phase, they must identify the efficacy. With more participants, the researchers get more people into the database and identify the effectiveness of the medicine. The dosage adjustment also identifies the safest possible dose of the medicine.

#3 – Third Phase

The Third phase is the last active phase of the trial. The researchers can invite and recruit many participants for better results. As the safety and effectiveness of the medicine are established, they have to finalize the data on the huge number of participants. This is quite useful as it enables them to know the side effects based on the various factors. Once done, they move to the final phase.

#4 – Final Phase

The final phase is not active, but a passive one. In this phase, the researchers aim to get the final approval from the regulatory authorities. The researchers collect all the data from the first three phases, create the reports and then apply for approval. There are no participants involved in this phase. Once the approval is received, the medicines are ready for public distribution.

Final Words

All of the medicines that we are using in our lives are approved through clinical trials. This highlights the importance of clinical trials for humanity.
