The scoop: Kolltan has been developing new oncology therapies based on the scientific work of Yale's Joseph Schlessinger, the co-founder of the company. The biotech has kept a low profile generally, but recently wooed Gerald McMahon, the Senior VP of oncology R&D at MedImmune, into the CEO's job. About 30 staffers are at work at the biotech, which has raised a total of some $75 million. Peter Hirth, the CEO at Plexxikon, sits on the board. The biotech is developing monoclonal antibodies that target receptor tyrosine kinases.
