Third Arc Bio Inc. has closed a $52 million series A extension to advance its pipeline of multifunctional antibodies for a range of oncology and immunology & inflammation (I&I) indications.

Scientists at Ghent University have created a mouse model that incorporates human versions of the receptors that recognize the fragment crystallizable (Fc) region of immunoglobulin G (IgG), one of the most abundant antibodies in the blood and a key mediator of essential immune functions such as cellular activation, pathogen elimination and the regulation of inflammatory responses. These human Fcγ receptors allow the humanized mouse to more accurately reproduce IgG-driven biology, enabling more reliable and safer preclinical assays before evaluating monoclonal antibodies in clinical trials with people.

Astrazeneca plc is investing $15 billion in China through 2030 to expand R&D and manufacturing, marking one of the largest long-term investments by a multinational pharma company in the country. The U.K.-based company also struck a deal worth up to $3.5 billion with China’s CSPC Pharmaceuticals Group Ltd. to accelerate the development of next-generation therapies for obesity and type 2 diabetes.

Genentech Inc. is paying $200 million up front and up to $1.5 billion in milestone payments to license one of Suzhou Sanegene Bio Inc.’s RNAi programs. Metabolic and autoimmune-focused Sanegene did not disclose specifics around the licensed candidate, except that it was derived from its LEAD (Ligand and Enhancer Assisted Delivery) platform.

Certain chemical compounds can disable the bacterial immune systems that protect them from viruses, making the bacteria vulnerable to infection. Scientists at Indiana University have discovered a promising compound that works in different types of bacteria and could be used to develop potent and diverse phage therapies against bacterial infections, ultimately giving clinicians more options against antibiotic resistance.

It’s not often that disclosure of a complete response letter (CRL) causes a company’s share price to rise, but that was case for Aquestive Therapeutics Inc., which saw its stock (NASDAQ:AQST) rise 39% to close Feb. 2 at $4.10 on news the U.S. FDA has declined – for now – to approve the NDA for Anaphylm (dibutepinephrine), delaying the commercial entry of what could be the first oral alternative to Epipen.

Liver fibrosis in the course of metabolic dysfunction-associated steatohepatitis could be significantly reduced using CAR T-cells generated in vivo. Scientists at the Icahn School of Medicine at Mount Sinai have developed an experimental cell therapy that eliminates only one type of liver cell, the stellate cells that express fibroblast activation protein alpha. This strategy not only reduced fibrosis but also reversed liver damage.

An Anglo-American team of researchers has devised a new computational method for quantifying Epstein-Barr virus (EBV) directly from human genome sequences and used this to identify 22 genes that link higher levels of the virus to a range of chronic diseases. The new method sets the scene for further exploration of biobank DNA sequence data to gain greater understanding of the nature and the role of the human virome, the 10(13) – largely unstudied – viral particles that coexist in humans.

The EMA has started a review of Amgen Inc.’s Tavneos (avacopan) after questions were raised about the integrity of the data in the Advocate study that the agency assessed when granting approval of the vasculitis treatment in January 2022.
