Clinical trials are large-scale research projects aimed at introducing new drugs to the pharmaceutical market. They provide patients with access to innovative pharmaceuticals, which are a chance to cure various diseases. At the same time, they allow pharmaceutical companies to verify whether and how the healing process works using the tested product. Therefore, clinical trials allow the assessment of the effects, absorption, distribution and metabolism of a pharmaceutical product, first and foremost in the consideration of the patient’s well-being and safety.
Over the centuries, the development of medicine has contributed to the fact that today people can reasonably expect to live much longer than their ancestors. Many previously incurable illnesses can nowadays be successfully treated with a properly selected drug. Our immunity has significantly improved, because dozens of diseases are prevented thanks to widespread vaccination. Each of these pharmaceutical products which play such an important part in prolonging average life expectancy has passed through the stage of clinical trials. They were all tested and improved before they could become available to patients. In the past, however, this process of testing and trials did not take place in such a strictly regulated way and according to such high safety standards. Today’s clinical trials methodology means that introducing pharmaceuticals to the market takes place with mutual benefits for the patient and for science.
Clinical trials are divided into stages, thanks to which patients receive pharmaceuticals thoroughly verified in terms of safety. It is assumed that only 1 out of 10,000 discovered molecules with therapeutic effects will eventually go on the market. It usually takes 10-15 years to monitor their therapeutic effects.
