Recludix Pharma Inc. has entered into a strategic collaboration with Sanofi SA to develop and commercialize first-in-class oral small-molecule STAT6 (signal transducer and activator of transcription 6) inhibitors for patients with immunological and inflammatory diseases. STAT6 is believed to play a key role in multiple dermatological and respiratory diseases.
Dismissed as undruggable in the early 2000s, Src homology 2 domains are now viable and at the heart of Recludix Pharma Inc.’s new deal with Sanofi SA’s U.S. unit. The two will collaborate on developing and commercializing treatments for immunological and inflammatory diseases. In the near term, Recludix will get $125 million, but long term it could add up to $1.2 billion in milestones. Recludix could also bring in up to double-digit royalties on possible future product sales.
Recent studies suggest that neutrophils are not only involved in the innate immune response but also may play extended roles in chronic inflammatory disorders and adaptive immune responses as well.
Researchers from Astrazeneca plc have presented a novel adeno-associated virus (AAV)-delivered human (h)IL-33 neutralizing scFv-based protein construct at the 2023 World Congress on Basic and Clinical Pharmacology.
A new study on the interleukin 1 (IL-1) pathway and its involvement in systemic inflammation and autoinflammatory diseases has described a mutation of the IL-1 receptor type 1 (IL-1R1) receptor associated with chronic recurrent multifocal osteomyelitis (CRMO). The variant p.Lys131Glu of this receptor was identified in a patient with CRMO. A peripheral blood mononuclear cell analysis showed an inflammatory event in lymphocytes, especially in monocytes and neutrophils. The research was conducted by a group of scientists at Zhejiang University in China and reported in the July 11, 2023, issue of Immunity.
The endogenous human protein annexin A1 (ANXA1) is a driver of inflammatory resolution and has shown protective effects in several models of diseases with inflammatory components, including myocardial infarction. Researchers from Resother Pharma A/S and colleagues reported on the preclinical cardioprotective role of RTP-026, a peptide derived from the ANXA1 N-terminal region that acts as N-formyl peptide receptor 2 (FPR2) ligand. In vitro, testing of receptor selectivity and activation in FPR2-HEK-293 cells showed an EC50 value between 10 and 30 nM.
In brain research, be it basic or clinical, neurons have long hogged the limelight. But at the 2023 European Meeting on Glial Cells in Health and Disease, neurons take a back seat to glia – cell types that have often been described as support cells and treated as an afterthought, but that play critical roles in all aspects of brain function, including information processing.
