Clinical studies

Why are clinical trials conducted?

Clinical trials help in finding answers to the introduction of new drugs and new uses of known treatments to the market. Clinical trials help with the verification whether new drugs are safe and effective. Properly conducted clinical trials are a fast and safe way to introduce a new and effective drug to the market.

What information is used from Clinical trials?

Any new drug goes through a variety of clinical trials and its phases. Each phase of the clinical trial is conducted and designed to answer specific questions.

Clinical trials are conducted at various stages of the whole clinical research. These are done to obtain further data and information about a new drug before the medication is approved and recommended for routine use.

There are four phases of clinical trials (preceded by detailed preclinical trials):

Phase I takes place on the basis of healthy volunteers and focuses on the efficacy, pharmacological properties and excludes the possible toxicity of new products and the determination of their acceptable dosage.

Phase II helps to find the optimal dosage and effectiveness of the treatment.

Phase III takes place on a larger number of patients and monitors the safety and efficacy of the new type of treatment compared to the standard treatment.

Phase IV continues with the testing of an already marketed medication to further collect information about the medicine in connection from the long term perspective.
