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 ick 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:
I.
Observational
trials
II.
Interventional
trials
Observational clinical trials
These are trials that
do not test drugs or treatments. In these type 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:
i.
Treatment
trials: These trials include test
treatments, drug combinations or surgical approaches to relieve and slow down
disease progression of people.
ii.
Prevention
trials: These include test approaches, medicines, vitamins, minerals, vaccines
or lifestyle changes that may lower the risk of developing diseases.
iii.
Screening
Trials: These trails test ways to detect illnesses such as cancer in their
early stages.
iv.
Quality
of Life trails: These trials discover ways to improve comfort and quality for
patients who suffer from various illnesses.
v.
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.
