All About Phase II Clinical Trials
Last month, we highlighted what to know about phase I clinical trials. In the second of our four-part series, we are discussing phase II clinical trials.
Phase II trials study how well a drug works against a particular type of cancer and typically enroll fewer than 100 patients. Phase II trials also gather more information about a drug’s safety. Phase I trials are sometimes combined with phase II trials to answer research questions more quickly and with fewer patients. Benefits and risks are similar to those of phase I trials, although more is known about the drug during phase II trials than during phase I trials.
Visit the links below for more information on the goals of phase II trials, as well as why phase I and phase II trials are sometimes combined.
