TOULOUSE, France--(BUSINESS WIRE)--Regulatory News:
ABIONYX Pharma (FR0012616852 - ABNX - PEA PME eligible) (Paris:ABNX), a new generation biotech company dedicated to the discovery and development of innovative therapies for patients, announced today the publication in Biomedecines of the first clinical data demonstrating that CER-001 limits inflammation effects in acute inflammatory conditions such as COVID-19.
COVID-19 is associated with respiratory symptoms characterized by acute lung injury, rapidly progressing to acute respiratory distress syndrome. The pulmonary dysfunction is rapidly accompanied by a major "cytokine storm" in which inflammatory cytokines are abundantly released into the bloodstream leading to host tissue damage.
Decreased levels of total cholesterol, LDL and HDL have been observed in patients with COVID-19 infections. Patients with low HDL levels at hospital admission have an increased risk of developing severe disease compared with patients with high HDL levels. With recovery from COVID-19 infections, serum lipid levels return to pre-infection levels
High-density lipoproteins (HDL) in addition to their reverse cholesterol transport function, exhibit pleiotropic properties, including antiinflammatory, anti-apoptotic, anti-thrombotic, and antioxidant functions.
CER-001 is an HDL mimetic previously tested in various pathological conditions, but never in COVID-19 before a compassionate access authorization (CAA) granted by the ANSM for bio-HDL (CER-001) in COVID-19 in January 2021.
The Biomedecines publication reports on the first clinical administration of recombinant HDL particles, CER-001, in a patient with severe COVID-19 infection in an intensive care unit.
Shotgun proteomics were performed on HDL before and after CER-001 infusions and serve to identify the type of proteins contained in HDL. These analyses demonstrated that apoA-I increased after injections while most pro-inflammatory proteins decreased following injections.
Measurement of serum amyloid A-1, inflammatory markers, and cytokines showed a significant decrease in most of them during CER-001 treatment. The results suggest recombinant HDL infusions are a potential therapeutic strategy to be explored in COVID-19 patients.
The publication shows for the first time that intravenous HDL supplementation (through CER-001 infusion for instance) is feasible in acute inflammatory conditions such as COVID-19, with a tendency to limit inflammation. HDLs have been shown to reduce inflammation in models of bacterial sepsis in part via their ability to bind and remove circulating endotoxins. However, in viral sepsis, HDL infusion may be also beneficial, particularly by reducing inflammationvia a still unknown mechanism. . This case report encourages the conduct of a randomized placebo-controlled trial to evaluate the contribution of rHDL in severe ICU COVID-19 patients.
This scientific publication, entitled "First Recombinant High-Density Lipoprotein Particles Administration in a Severe ICU COVID-19 Patient, a Multi-Omics Exploriatory Investigation," is available online in the journal Biomedecines: https://www.mdpi.com/2227-9059/10/4/754/htm
ABIONYX Pharma is awaiting further results from ongoing clinical studies in inflammatory conditions.
