Regional Cancer Center ~ Erie, PA

Clinical Trial Phases

Cancer clinical trials include research at three different phases. Each phase answers different questions about the new treatment. Phase I trials are not conducted at RCC; the majority of trials open at RCC are Phase III trials.

Phase I Trials

Phase I trials are the first step in testing a new treatment in humans. These studies usually include only a limited number of patients who would not be helped by other known treatments.

Phase II Trials

Phase II trials focus on learning whether the new treatment has an anticancer effect, such as shrinking a tumor or improving blood test results.

Phase III Trials

Phase III trials compare the results of people taking the new treatment with results of people taking standard treatment to compare variables such as survival rates and side effects. In most cases, studies move into Phase III testing only after a treatment shows promise in Phases I and II.


The Center’s certified regional tumor registry tracks treatment and outcomes of cancers for study by health care and research professionals. In this way, the Center and its patients are contributing to the ultimate fight against cancer.
