Immetas Therapeutics Inc. and GC Biopharma Corp. have entered into a research collaboration to discover and develop novel mRNA therapeutics for the treatment of a broad range of autoimmune diseases. The collaboration combines Immetas’ proprietary platform for modulating innate immune pathways with GC Biopharma’s mRNA therapeutic and lipid nanoparticle (LNP) delivery platforms.
The NLRP3 inflammasome is a multiprotein complex that plays a pivotal role in regulating the innate immune system and inflammatory signaling. Upon activation by pathogen-associated molecular patterns (PAMPs), NLRP3 oligomerizes and activates caspase-1 which initiates the processing and release of pro-inflammatory cytokines IL-1β and IL-1 that are overproduced in many inflammatory disease conditions.
Ventus Therapeutics Inc. closed a $100 million series B round less than 12 months after raising $60 million in series A funding, to continue development of several preclinical programs informed by novel insights into the structural biology of key targets associated with innate immune signal pathways implicated in a wide range of disease areas.
With a just-completed $100 million common stock financing, Flame Biosciences Inc. plans to target the inflammasome, a protein complex that sets off innate immune responses by activating the cytokines IL-1beta and IL-18.
Researchers at the University of Virginia have used a retrospective database analysis to show that the use of nucleoside reverse transcriptase inhibitors for the treatment of HIV or hepatitis B reduced the risk of developing type 2 diabetes by 33%.
DUBLIN – Roche Holding AG is taking a second shot on the NLRP3 inflammasome by acquiring Dublin-based Inflazome Ltd. for €380 million (US$447.8 million) up front plus undisclosed milestones linked to the progress of its two clinical-stage candidates inzomelid and somalix. In terms of cash on the table, the deal is the largest yet for a portfolio of drug candidates that acts on the NLRP3 inflammasome, and it represents a profitable exit for Inflazome’s investors, who put €55 million into the company over two funding rounds, in 2016 and in 2018.
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.
DUBLIN – After 18 months in stealth mode, Ventus Therapeutics Inc. has emerged with $60 million in series A funding and big ambitions to bring insights from structural biology to bear on two key aspects of innate immunity, inflammasome activation and cGAS-Sting signaling.
