Cytomx Therapeutics Inc. CEO Sean McCarthy told BioWorld that the longish hiatus between deals broken by the tie-up with Astellas Pharma Inc. was “very deliberate. Over that period of time, we were generating our first clinical data to get experience with how the technology works in cancer patients with our first two lead programs,” both of which have reached the phase II stage. A year ago in January, he said, the South San Francisco-based firm brought aboard Chief Business Officer Nick Galli to “hit the gas pedal a bit more in business development,” which led to the signing with Astellas, of Tokyo. Shares of Cytomx (NASDAQ:CTMX) closed March 24 at $6.53, up $1.60, or 32%.
