Clinical trials for lung cancer aim to find out if a new treatment might be more effective than a current treatment.

Trials aim to find out if a new treatment:-

  • Is safe.

  • Has side effects.

  • Works better than the currently used treatment.

  • Helps you feel better.

Phase 1 trials predominantly look at doses and the side effects of a new treatment. It usually involves a small group of people and whilst some participants do see benefits, many do not.

Phase 2 is an extension on phase 1 and looks to see if the new treatment works well enough to test in a larger phase 3 trial.

Patients participating in this trial may still experience side effects that doctors didn’t previously know about. Some phase 2 trials are randomised, and some involve a placebo treatment.

Phase 3 trials compare new treatments against the current standardized treatment to see if it works better. Most phase 3 trials are randomized. This means you are put into groups, usually by a computer. Each group will then receive a different treatment, for example one group will receive the standard treatment whilst the other will receive the new treatment.
