This published table summarizes the clinical trial results for a colon cancer drug, panitumumab (Vectibix™). The experimental group is summarized in the middle column, described as P + BSC, i.e., experimental drug (panitumab) plus best supportive care (BSC). The far right column is the control group, who received the best supportive care (BSC) without the experimental drug. The drug study data in Table 3 is “statistically” significant. What does that term mean, precisely? Consider the difference between the medians for...

Clinical trials are usually conducted in phases that build on one another. Each phase is designed to answer certain questions. Knowing the phase of the clinical trial is important because it can give you some idea about how much is known about the treatment being studied. There are pros and cons to taking part in each phase of a clinical trial. Phase I clinical trials: Is the treatment safe? Phase I studies of a new drug are usually the first...
