LONDON – With results of its first phase I trial imminent, inflammasome specialist Nodthera Ltd. has raised $55 million in a series B round, providing funding for phase II proof-of-concept studies and to advance a second, brain-penetrant, compound to the clinic.

The $65 million that Hotspot Therapeutics Inc., of Boston, raised will help advance its lead programs to the clinic, including protein kinase C antagonists for Th2 and T-reg-driven autoimmune disease and S6 kinase antagonists for rare metabolic disease.

Due to launch in the second half of this year, Rallybio Inc.’s phase I/II study testing RLYB-211 for prevention of fetal and neonatal alloimmune thrombocytopenia (FNAIT) will begin with experiments in men, said Steve Uden, one of the company’s three founders. “The good news is, we can confirm the safety and the pharmacology of this concept in male volunteers before having to start a clinical trial in pregnant mothers,” he told BioWorld.

DUBLIN – Compass Pathways Ltd. raised $80 million in a series B round to continue its development of the psychedelic drug psilocybin in treatment-resistant depression.

With completion of a $120 million series B financing, Affinivax Inc. said it's poised to advance several new vaccine candidates for hospital-associated infections into the clinic even as its partner, Astellas Pharma Inc., carries its lead pneumococcal vaccine candidate, ASP-3772, through an upcoming phase III program.

Privately held Cerevance Inc., of Boston, raised $45 million in a series B designed to propel the discovery and development of therapies for treating CNS diseases such as Alzheimer’s disease.

Backers in Tango Therapeutics Inc.’s $60 million series B round represent “a group of really smart crossovers who normally don’t come in quite this early” and “hung in there” during some especially hard times on Wall Street recently, CEO Barbara Weber told BioWorld. “We were about to sign the term sheet the first time the market crashed, which was a little nerve-wracking.”

Kendall Square was a great jumping-off point for Cambridge, Mass.’s Pandion Therapeutics Inc. but with an $80 million series B in its pocket, the time has come to pick up sticks to accommodate its growth.

Cambridge, Mass.-based Elevatebio LLC has triple-pronged plans for its $170 million series B round, which the company said will be directed toward manufacturing cell and gene therapies, enabling new technology platforms, and pursuing therapeutics.
