EXCERPT
Thirteen years ago, I wrote an editorial applauding discovery, development, and marketing approval of imatinib for chronic myelogenous leukemia (CML), a signal event in the history of targeted therapy, and the oncology equivalent of the four-minute mile [1]. It took 3 years from the start of trials and required the confirmatory evidence of two phase II studies to receive the U.S. Food and Drug Administration’s (FDA) stamp of conditional approval. A decade later, these pages called attention to the rapid 3-year development of crizotinib for ALK-translocated non-small cell lung cancer (NSCLC), again based on a highly positive phase I and a confirmatory phase II [2]. In that editorial, I predicted that, someday soon, the FDA would approve a new targeted agent after phase I. That day has come to pass with the approval of ceritinib for ALK-rearranged NSCLC.
The strategy for targeted drug development is now radically different from the equivalent trials of cytotoxic drugs. In the case of ceritinib, the research team knew the drug’s target, were able to select the patients that have tumors expressing the target, and could quickly expand the phase I study to include large numbers of patients, thereby accumulating convincing data on efficacy and safety in phase I. The old saw that phase I is all about safety and phase II is all about efficacy no longer applies. Phase I is all about Proof of Principle and efficacy, once a safe dose is reached. [sounds familiar]

to my mind, the above means Kevetrin is setting up well... how "convincing" the data coming out of K's Ph I in adv of the planned Ph IIs---now that is the Q... hints, but more proof obv needed. if it adds months in PFS, Breakthrough Designation likely
