The Value Of Clinical Trials In Drug Development

Written by  The Dubrovnik Times Aug 07, 2022

Medical researchers rely on clinical trials as a critical research tool for improving patient care and medical understanding. Sometimes doctors don't know whether a new treatment or strategy works well and is safe for individuals or which therapies or procedures work best for certain illnesses or groups. That’s why they do clinical research. 

It is critical to conduct clinical trials to discover novel disease treatments and new techniques to detect, diagnose, and prevent disease. It is impossible to determine what works in the laboratory or on animals and what does not in humans until clinical trials are conducted. In addition, clinical trials assist doctors in deciding if the risks and benefits of new medication are balanced. The findings of clinical trials are unknown to researchers. (If they did, the trials would be unnecessary.) 

Due to inherent uncertainty, patients may be wary of signing up for a clinical trial. People have benefited from clinical trials because of the efforts of others who opted to participate in research that led to better treatment for a disease or condition.

What Are The Following Phases Of A Clinical Trial?

Clinical trials have four stages and add to medical knowledge in treatment, diagnosis, and prevention. The FDA aggressively reduces participant hazards but cannot be avoided entirely because clinical research is fraught with uncertainty.

  • PHASE 1

A group of fit and well-intentioned volunteers (20–80 people) is subjected to the experimental treatment to identify the optimal dosage and the product's safety and adverse effects.

  • PHASE 2

Larger groups (100–300 patients) with a known disease or condition are used to test the experimental treatment. Preliminary effectiveness data is gathered in this phase. This phase can endure for several years because of the need to monitor therapy safety and short-term adverse effects.

  • PHASE 3

Several hundred to about 3,000 people from various populations are subjected to the experimental treatment to evaluate its safety and efficacy at multiple dosages and in combination with other medications. FDA approval of an investigational drug or technology is almost always a conclusion after a successful clinical trial. 

  • PHASE 4

After the FDA has approved the experimental treatment, this phase begins. The efficacy and safety of the therapy are being closely studied in large, diverse groups. Sometimes the adverse reactions to a particular treatment aren't apparent until many people have been exposed to it for some time.

Because of the lengthy and challenging FDA approval procedure, only one out of every ten medications that enter clinical testing makes it to market.

What Is The Importance Of Clinical Trials In Drug Development?

New treatments cannot be developed without conducting clinical trials. Here are the different reasons why clinical trials are important in drug development.

  • Clinical Trials Can Determine The Cost-Effectiveness Of A Drug

Clinical trials can reveal whether a treatment is cost-effective. Each experiment is carried out under a detailed blueprint known as a protocol. The strategy lays out who can participate in the trial, what tests and procedures are performed, what medications will be used, how much drug will be administered, and how long the trial will last. Endpoints (observables) and the data collected are used to secure marketing permission and payment from payers.

Phased clinical trials are the norm. Each phase is designed to address specific issues while ensuring the safety of those participating. Before the FDA can approve a new drug, it must undergo three clinical study stages. Clinical trials are done under Good Clinical Practice (GCP) principles to ensure the safety of patients.

  • Clinical Trials Can Determine Whether A Diagnostic Test Is Clinically Useful And If Treatment Enhances The Quality Of Life

Knowing the clinical value of diagnostic tests and the cost-effectiveness of a treatment that enhances the quality of life in clinical trials is crucial. Patients and doctors’ benefit from these studies because they help them determine the safety and efficacy of current treatments and the advantages and disadvantages of alternatives. 

Patients' best interests are to participate in clinical trials to receive the best possible medical treatment. Patients participate actively in their healthcare and contribute to medical research in clinical trials. Patients also participate actively in acquiring access to innovative research treatments that are not yet accessible on the market, which contributes to the advancement of medical science.

The Takeaway

The conduct of clinical trials is a critical element of the research process for medical advancement. An essential phase in the FDA's medication-approval procedure, they provide researchers with crucial information about a drug’s efficacy and adverse effects. One importance of clinical trials is that researchers look at drug effectiveness, potency, dosage, side effects, and influence on specific demographic groups. 

Clinical trials are well-designed to benefit all medical community members, including participants, investigators, sponsors, and others. An enormous number of experimental medications and therapies are still being tested in clinical trials to understand diseases better, diagnose acute or chronic illnesses earlier, and ensure the creation of new medical advances.
