Stages of a new therapy

Phases in clinical trials

Each research project consists of several phases, during which progressively more questions are answered.

I

Phase

A phase that determines the highest dose of a drug a patient can take without experiencing side effects. The safety of participants is paramount, which is why only a few dozen people take part in this phase.

II

Phase

This is the time for the first evidence of efficacy. The aim of this phase is to confirm that the investigational product works as expected and to determine the optimal dose. Several hundred people are already participating in the study.

III

Phase

At this stage, more than a thousand patients are already participating. Thanks to a large study population, the results are more reliable and allow for the assessment of a drug’s efficacy and safety in a broad population. This is a key step before the registration of a new therapy.

IV

Phase

Concerns medicines already approved for use. It allows monitoring of their long-term effects, effectiveness in routine clinical practice, and any rare adverse reactions.
