    Although not officially announced by the company itself, an SEC filing showed that Treeline Biosciences – which has a reputation for being quite secretive – raised $421 million in October’s biggest fundraising round. The drug discovery company is thought to be working on molecular targets in oncology that are difficult to drug, as well as other therapeutic areas. 

    The second biggest funding round of last month went to Kailera Therapeutics, as it launched with $400 million in series A financing to with a portfolio of obesity assets acquired from China. Meanwhile, the third largest round went to Seaport Therapeutics, which raised $225 million in oversubscribed series B funding to advance its clinical-stage pipeline of neuropsychiatric drugs through important clinical milestones and further advance the capabilities of its technology platform.
