22 March 2021 - - US-based biotechnology company BioAge Labs, Inc has commenced a Phase 2 clinical trial of BGE-175, a potent oral inhibitor of prostaglandin D2 (PGD2) DP1 signaling with a safety database comprising > 2400 patients, for treating COVID-19 patients aged 60 or older, the company said.

Top-line results are expected in 2021.

The preclinical data were obtained in collaboration with coronavirus expert Stanley Perlman, M.D., Professor of Microbiology and Immunology at the University of Iowa.

The randomized, placebo-controlled, parallel-group, multicenter, double-blind study will recruit patients ≥ 60 years old hospitalized for COVID-19 who are not yet in respiratory failure.

A total of 132 participants will receive daily doses of BGE-175 or placebo (66 in each group) for up to 14 days.

The study medication will be administered orally or, in patients who cannot swallow, via nasogastric tube. The trial is being conducted in the US, Argentina, and Brazil.

The primary endpoint is the proportion of patients who die or progress to respiratory failure within 28 days after receiving the first dose of BGE-175.

Secondary endpoints include viral load, clinical improvement or worsening, incidence and duration of supplementary oxygen or ventilation, time to discharge or rehospitalization, and intensive care unit admission, all over a 57-day period after the first dose.

The study will also measure PGD2 DP1 signaling activity and the levels of inflammatory markers.

Some cases of COVID-19 are associated with uncontrolled inflammation, which increases disease severity and morbidity.

Hence, the trial will also measure BGE-175's effect on levels of inflammatory markers, including cytokines, CD4+ and CD8+ T cells, and total lymphocytes. The resultant data will provide insight into BGE-175's ability to restore normal regulation of the immune system.

Aging is the largest risk factor for COVID-19 morbidity and mortality: people over 80 are hundreds of times more likely to die of the disease than those under 40.

Older people are at higher risk in part because the aging immune system becomes less efficient and prone to hyperinflammation.

Rejuvenating the immune system by treating age-related deterioration directly could help to lessen the severity of COVID-19 infection and boost protection by vaccines.

BGE-175 is a potent, orally administered small-molecule inhibitor of the PGD2 DP1 pathway, which BioAge's platform identified as a key target for immune aging.

DP1 signaling is associated with elevated susceptibility to infection and higher risk of mortality from infectious disease. Inhibition of DP1 affects immune function in multiple ways, activating dendritic and natural killer cells while attenuating neutrophil migration.

Together, these effects counteract immunosenescence and improve aspects of both adaptive and innate immunity.

Multiple Phase 1–3 clinical trials of BGE-175 for allergic rhinitis, conducted by Shionogi and Co., Ltd., demonstrated that the drug was safe and well-tolerated in more than 2,400 study participants.

The BioAge platform identifies key drug targets that impact aging. The company's proprietary human aging cohorts include archived longitudinal blood samples collected up to 50 years ago, with participant -omics data that is tied to extensive medical follow-up records including detailed future healthspan, lifespan, and disease outcomes.

BioAge has built a systems biology and AI platform that leverages these rich datasets to generate hypotheses about the determinants of healthy human aging and identify the molecular drivers of age-related pathology.

BioAge's pipeline of development candidates targeting these key pathways has the potential to address significant unmet medical needs of the aging population.

BioAge is a biotechnology company that develops proprietary drugs to treat aging and aging-related diseases.

Since its founding in 2015, the company has raised more than USD 127m in venture capital funding from Andreessen Horowitz, Kaiser Foundation Hospitals, Khosla Ventures, Felicis Ventures, and others to back its AI-driven approach of mapping the molecular pathways that impact human longevity.

BioAge's mission is to develop a pipeline of therapeutic assets that target aging to treat severe diseases.
