CohBar Confirms Efficacy of Novel Apelin Agonists in Acute Respiratory Distress Syndrome (ARDS) Model
CohBar, a clinical-stage biotechnology company, announced promising preclinical data on its apelin agonist peptides, indicating efficacy in treating acute respiratory distress syndrome (ARDS), including COVID-19 associated ARDS. The study demonstrated that CB5064 Analog significantly reduced lung fluid accumulation and pro-inflammatory cytokines in a mouse model. This represents a potential breakthrough for the estimated three million patients globally suffering from ARDS. CohBar plans to continue studies and present findings at a future conference.
- Promising preclinical data indicating efficacy of apelin agonist peptides for treating ARDS and COVID-19 associated ARDS.
- Significant reduction in lung fluid accumulation and pro-inflammatory cytokines observed with CB5064 Analog compared to placebo.
- Potential to address a major unmet medical need as there are currently no approved therapeutics for ARDS.
- None.
MENLO PARK, Calif., Dec. 09, 2020 (GLOBE NEWSWIRE) -- CohBar, Inc. (NASDAQ: CWBR), a clinical stage biotechnology company developing mitochondria based therapeutics to treat chronic diseases and extend healthy lifespan, today announced new preclinical data confirming the efficacy of its apelin agonist peptides in a preclinical model of acute respiratory distress syndrome (ARDS). The company expects the apelin agonists to have potential to treat COVID-19 associated ARDS as well as ARDS patients in general, of which there are approximately three million globally.
“These new positive preclinical results confirm previous data showing CB5064 Analogs reduce fluid accumulation and pro-inflammatory cytokine secretion, key processes underlying the lethal consequences of severe ARDS and COVID-19 associated ARDS,” said Kenneth C. Cundy, PhD, CohBar’s Chief Scientific Officer. “By engaging the apelin pathway, CohBar’s novel approach has the potential to treat ARDS and COVID-19 associated ARDS, while also reducing the global damage caused by a cytokine storm that reaches beyond the lungs to other organs such as the kidneys, liver, and heart. We plan to complete additional ongoing studies and submit the combined data for presentation at a future scientific meeting.”
In the preclinical study, acute lung injury was induced in mice by administration of lipopolysaccharide (LPS), a bacterial toxin that produces similar symptoms to other causes of ARDS, including fluid accumulation and cytokine secretion. A single dose of CB5064 Analog was administered one hour prior to the LPS exposure and effects on lung weight and levels of pro-inflammatory cytokines were measured at 4 hours after LPS exposure. Treatment with CB5064 Analogs reduced fluid accumulation in the lungs and a corresponding broad reduction in levels of key pro-inflammatory cytokines secreted into the lung fluid, when compared to treatment with a placebo control.
“ARDS is a major unmet medical need and there are no approved therapeutics for this devastating condition,” stated Professor Toby Maher, Director of Interstitial Lung Disease and Professor of Medicine at the Keck School of Medicine, University of Southern California. “The data for CohBar’s apelin agonists in this preclinical model are encouraging and support further advancement of the program towards candidate selection for clinical testing.”
Further details of these new data will be available on the CohBar website at www.cohbar.com.
About the Apelin Receptor and Apelin
The apelin receptor is broadly expressed and abundant in lung tissue and published preclinical studies have shown that apelin signaling can reduce the severity of acute lung injury, by reducing lung fluid accumulation, hypoxemia, and cytokine secretion, which also occur in COVID-19 associated ARDS and lead to downstream injury to kidney, heart, and other organs.
Apelin is an endogenous peptide released by fat cells that activates the apelin receptor, a key cell surface receptor involved in protective regulation of fluid homeostasis, cardiovascular function, and metabolism. In addition to its protective effects in lung injury, apelin has also been shown to reduce body weight and improve insulin sensitivity in obese mice. Published clinical reports show that obesity and diabetes are major underlying risk factors in severe COVID-19, with a mortality rate of
About ARDS
In addition to COVID-19, ARDS can be triggered by viral or bacterial pneumonia, sepsis, trauma or other events and represents a major cause of morbidity and mortality. There is an unmet need for a safe and effective treatment of ARDS due to its high mortality rate and lack of effective drug treatments. It also prolongs hospital stays and requires convalescence in the hospital and rehabilitation. An effective therapy would reduce time on ventilators and in the ICU, reduce mortality, and improve quality of life. ARDS affects approximately three million patients globally.
About CohBar
CohBar (NASDAQ: CWBR) is a clinical stage biotechnology company focused on the research and development of mitochondria based therapeutics, an emerging class of drugs for the treatment of chronic and age-related diseases. Mitochondria based therapeutics originate from the discovery by CohBar’s founders of a novel group of naturally occurring peptide sequences within the mitochondrial genome, some of which have been shown to have the potential to regulate key processes in multiple systems and organs in the body. To date, the company has discovered more than 100 mitochondrial derived peptides and generated over 1,000 analogs. CohBar’s efforts focus on the development of these peptides into therapeutics that offer the potential to address a broad range of diseases because of the underlying impact of mitochondrial dysfunction. The company’s lead compound, CB4211, is in the Phase 1b stage of a Phase 1a/1b clinical trial for NASH and obesity. In addition, CohBar has four preclinical programs: CB5138 Analogs for fibrotic diseases, CB5064 Analogs for COVID-19 associated ARDS, MBT5 Analogs for CXCR4-related cancer and orphan diseases, and MBT3 Analogs for cancer immunotherapy.
