They need to involve lots of patients in the ultimate target population to see if the new drug is better than the standard treatment or another option being considered. The outcome of this phase is to determine the dose that should be used in trials going forward, and it gives doctors a better idea of what side effects to expect as they begin to treat more patients in future clinical trials. The researchers are looking for even small signs of benefit to the patients, as those on a phase 2 trial may have disease that has worsened on standard treatments, and so are harder to treat. This helps investigators determine whether the drug improves outcomes for patients. The main objective of the phase 4 trial is to check the drug's performance in real life scenarios, to study the long-term risks and benefits of using the drug and to discover any rare side effects.
