There are 3 main phases of clinical trials:

• Phase 1 is the earliest stage of research, where there is often a focus on understanding if the treatment is safe or if it causes any side effects.
• Phase 2 still focuses on safety and side effects, but also tries to find out more about what is the best dose.
• Phase 3 often compares the new treatment to existing treatments or lookalike medications.

As drugs or interventions move into the different phases, the number of people taking part will increase. Not all studies will make it to the later phases, especially if the intervention is not found to be safe or effective in phase 1 and 2.

Some studies offer an extension phase of research, where people continue to receive the new drug or therapy after the initial trial has finished. The extension phase is often ‘open-label’, which means that you will know that you are receiving the active treatment .

Within studies, there are different requirements that someone must meet, to be able to take part. Some studies recruit people who are taking antifibrotic medications, including nintedanib or pirfenidone. However, in other studies people taking part must not be taking antifibrotic medication.
