Cumulus Oncology Ltd. is in the thick of raising a $50 million series A round as its model of sourcing novel drug targets emerging from academia, shaping them up for clinical development, and spinning them into startups, gathers pace. At the same time, Nodus Oncology Ltd., the first spinout created around an acquired asset, has just reached in vivo proof of concept with its lead DNA damage response inhibitor, and it, too, is looking to raise a series A to take the program through to the end of phase I.
