Yale University spinout Kleo Pharmaceuticals Inc. raised a series A to fund development of its antibody recruiting molecules, or ARMs, and synthetic antibody mimics, or SyAMs, developed in the lab of Yale researcher David Spiegel, who founded the New Haven, Conn.-based company last year. Kleo principals were mum on the amount of the round, but the sole investor was Biohaven Pharmaceutical Holding Co. Ltd., also of New Haven, which holds other intellectual property (IP) from Yale and was said to take a "substantial" equity stake in the newco.
