SHREWSBURY, MA, March 20, 2025 /24-7PressRelease/ -- SignaBlok, Inc., a preclinical stage biotechnology company pioneering first-in-class, new mechanism-based peptide therapies for multiple diseases, today announced it will present positive preclinical data detailing therapeutic activity of its leading macrophage-restricted TREM-1 inhibitor in experimental sepsis, acute respiratory distress syndrome (ARDS), and pulmonary fibrosis (PF) at the RIS and ATS Conference in San Francisco, California from May 16-21, 2025.

Details on SignaBlok's upcoming 2025 RIS and ATS poster presentations are as follows:

• In septic animals, TREM-1 blockade by SignaBlok's first-in-class macrophage-restricted TREM-1 inhibitor protects from death with the level of protection not declining at delayed treatment times
• In rats, macrophage-restricted TREM-1 blockade significantly reduces lipopolysaccharide (LPS)-induced neutrophil accumulation in the lungs when injected after, but not before, LPS challenge
• In mice with bleomycin-induced pulmonary fibrosis,TREM-1 blockade reduces the rate of progression and reverses fibrosis in the prevention and treatment models
• Data highlight potential of SignaBlok's SCHOOL technology platform to support clinical development of TREM-1 drug with minimal risk of failure due to a new mechanism of action

About TREM-1
Triggering receptor expressed on myeloid cells 1 (TREM-1) serves as an inflammation amplifier. As such, TREM-1 is involved in the pathogenesis of sepsis, ARDS, PF, and other inflammatory pathologies. Clinical targeting of TREM-1 is challenging due to multiple known and still unidentified TREM-1 ligands.

About SignaBlok
SignaBlok, Inc. is a Massachusetts-based biotechnology company founded in 2009 to develop innovative, first-in-class therapeutics for targeted treatment of inflammation-associated diseases through the use of two key SignaBlok's proprietary technologies: 1) new mechanism-based approach to inhibition of cell receptors by using innovative, ligand-independent inhibitory peptides (the so-called SCHOOL peptides, the abbreviation coming from the "Signaling Chain HOmoOLigomerization" model of immune signaling); and 2) nature-inspired, multifunctional nanotechnology for targeted drug and/or imaging agent delivery to macrophages.
