In Phase I clinical trials, doctors are primarily studying the safety of giving new drugs to humans, while also looking for the best way to give a medication (for example, as a pill, an injection, or an infusion). They will usually study how the drug is eliminated from the body in humans. Also, doctors are trying to find the right doses for further testing. They carefully watch for any side effects. Phase I study drugs are usually given to small groups of humans. During this phase, for drugs used to treat cancer, investigators may be able to find out which tumors a treatment works best in.
