Growing Demand for Clinical Research Professional
The Clinical Research field has a massive demand for trained clinical research professionals due to the huge gap between the demand and supply of qualified professionals. They are in demand due to the recent developments in research, presence of an aged population and prevalence of various diseases such as cancer and diabetes .Therefore the industry in in the lookout for professionals who can conduct clinical trials effectively from the beginning to the end.
The Need for Clinical Trials in the medical Sector
Clinical trials often referred to as clinical studies or more broadly as clinical research are research studies including human volunteers. Healthcare professionals conduct a wide range of clinical trials assess the safety and effectiveness of better ways to treat sick patients with chronic diseases .Moreover, these trials give healthcare professionals several insights into a disease and the treatment regime for these chronic cases. Therefore, Clinical trials are a vital part of the scientific research process and are essential to developing better treatments for people with illnesses.
Types of Clinical Trials
Clinical trials can be divided into 2 types. They are:
- Observational trials
- Interventional trials
Observational clinical trials
These are trials that do not test drugs or treatments. In these types of trials, clinical research professionals are observed by monitoring their health over a period of time. Therefore, these studies provide researchers with data that gives them an overall understanding of the disease and how the patient can be cured of the disease.

Interventional clinical trials
The main aim of interventional trials is to get more details about a particular intervention or treatment. Moreover, the people taking part in interventional trials are put into different treatment groups so that the research team can make a comparison of the results.
Sub Divisions of Clinical Trails
These broad categories are further classified into:
- Treatment trials: These trials include test treatments, drug combinations or surgical approaches to relieve and slow down disease progression of people.
- Prevention trials: These include test approaches, medicines, vitamins, minerals, vaccines or lifestyle changes that may lower the risk of developing diseases.
- Screening Trials: These trails test ways to detect illnesses such as cancer in their early stages.
- Quality of Life trails: These trials discover ways to improve comfort and quality for patients who suffer from various illnesses.
- Genetics Trials: They are trials that are designed to improve the ability to look for an inherited risk of diseases namely cancer and diabetes.

Phases of Clinical Trials
Clinical research trials are conducted in 4 phases to test the efficiency and safety of a drug, device and treatment regime
Phase I trials test a potential therapy, procedure or drug for the first time in human beings. The aim of healthcare professional during the first phase of clinical trials is to establish that a potential new treatment is safe for humans. For this reason, Phase I trials are typically conducted in very small groups of ten to eighty people.
Phase II involves trials that evaluate a treatment’s safety and effectiveness in a larger group of participants in a detailed manner. This phase usually includes a group of 100 to 300 people.
Phase III is usually conducted to confirm a therapy’s effectiveness, monitor side effects and make a comparison among a large group of people around thousand to three thousand in number . Besides that, the third phase is usually conducted at multiple centers and evaluate whether a treatment will benefit people with chronic diseases and if the benefits of a therapy outweigh the risks.
Phase IV known as the post marketing surveillance are conducted after a treatment has received approval and been introduced in the market. These trials help further evaluate long-term side effects and potential new uses for other conditions.
In order to gain more knowledge about these trials, individuals should enroll themselves in clinical research courses.
To conclude, the clinical trials process comprises an extensive amount of research that helps medical professionals in the advancement of drugs, devices and treatment regimes. For that, they need to undergo clinical research practical training programs to be capable to carry out their tasks as a clinical research professional.
