About Celtaxsys

Celtaxsys operated as a clinical-stage biopharmaceutical company headquartered in Atlanta, Georgia, focusing on the development of treatments for severe inflammatory diseases. The firm was founded in 2005, with William Reddick named as a founder and acting as the company's Chief Financial Officer. Greg Duncan later led the company as President and CEO. The company is now considered inactive, with reports suggesting it ceased operations around August 2020.

The company's core business was centered on discovering and developing drug compounds aimed at modulating the immune system to combat inflammatory and autoimmune diseases. Celtaxsys's strategy involved creating a pipeline of first-in-class immuno-modulators. The primary revenue model for a company at this stage is typically based on securing funding through financing rounds and grants to support research and development, with the long-term goal of monetizing its drug candidates through partnerships, licensing agreements, or acquisition.

Celtaxsys's lead product candidate was acebilustat (formerly CTX-4430), an oral, once-daily drug designed to treat inflammatory conditions. Acebilustat is a small molecule inhibitor of leukotriene A4 hydrolase (LTA4H), a key enzyme in the production of leukotriene B4 (LTB4), which is a significant promoter of inflammation. By inhibiting this enzyme, the drug aimed to re-balance an overactive inflammatory response without compromising the immune system's ability to fight infection. The drug was primarily developed for patients with cystic fibrosis (CF) to preserve lung function and reduce pulmonary exacerbations, and it had been granted Orphan Drug Designation in both the U.S. and the European Union. In August 2018, it was announced that acebilustat failed to meet the primary endpoint of improved lung function in a Phase 2 trial, though the company noted a benefit in reducing pulmonary exacerbations.
