What are the Four Phases of Clinical Trials?

Have you ever wondered how doctors access the latest medicines to administer to patients? Clinical trials are conducted to identify the safety and effectiveness of the latest medicines. Without passing through clinical trials, no allopathic medicine can be made available to the people.

Researchers divide clinical trials into multiple phases. If you are curious about these phases, then you are at the right place. In this post, you will learn about all four phases of clinical trials.

Different Phases of Clinical Trials

#1 – First Phase

The first phase is the trial phase, with at most 100 participants. This phase aims to test the new medicine on humans and understand safety. The researchers use the smaller doses of the medicine and then administer the same to Participants. After that, they started monitoring the participants’ health vitals. If there are no side effects or safety concerns, they increase the dose and understand the safe dose limit. Once the baseline is established, the next phase is commenced.

#2 – Second Phase

The second phase is bigger, as the researchers invite more participants for better results. In this phase, the aim is to find the effectiveness of the medicine. The researchers administer the medicine to the participants and then observe the vitals to identify if it’s working effectively in curing or managing the disease or health condition. Once the effectiveness of the medicine is established, the researchers move to the third phase.

#3 – Third Phase

The Third phase is all about mass testing, as it contains a lot of participants. There are more than a few participants in this phase as it helps researchers to identify the overall safety and efficacy of the medicine in the huge groups. This is an important phase, as it helps researchers to collect reliable data.

#4 – Final Phase

The fourth phase is the final phase of the trial. In this phase, the researchers and doctors collect all the data, analyze it, and generate a report. This report has to be sent to the Regulatory authorities for final approval. After that, the authorities will analyze the data and provide the final approval for the medicine or the treatment options.

Final Words

Clinical trials pave the way for groundbreaking medicines to reach the end customers. It takes a lot of time and effort for researchers to design and execute a clinical trial. Hence, we should appreciate their efforts. In this post, we tried our best to explain everything about the various phases of clinical trials.
