NORTH BRUNSWICK, N.J., June 10, 2025 (GLOBE NEWSWIRE) -- BioAegis Therapeutics, a pioneering biotech company at the forefront of innovative therapies for acute and chronic inflammatory diseases, announces that it will conduct a Phase 2 study of rhu-pGSN for decompression sickness (DCS) under a contract awarded by the U.S. Navy's Office of Naval Research to the University of Maryland School of Medicine (UMSOM). This work is the culmination of an extended collaboration with Dr. Stephen Thom, Professor of Emergency Medicine at UMSOM. The Company's portfolio is built around gelsolin, a highly conserved and critical immune regulatory protein which rebalances dysfunctional inflammation without suppressing immune function.
Phase 2 Clinical Trial of Rhu-pGSN
The study, 'Rhu-pGSN to Mitigate Proinflammatory Responses to Decompression in Healthy SCUBA Divers,' NCT06216366 is being conducted under a contract with the Office of Naval Research with the University of Maryland. It will investigate the use of rhu-pGSN as a pre- or post-exposure intervention in healthy trained SCUBA divers exposed to controlled hyperbaric conditions. The study is designed to assess the impact of rhu-pGSN on key inflammatory responses and microparticle production associated with decompression.
Decompression sickness occurs when inert gas bubbles form in the bloodstream and tissues due to rapid pressure changes, triggering an inflammatory cascade. Previous studies have shown that individuals with DCS exhibit depleted levels of plasma gelsolin and elevated levels of microparticles that contain inflammatory cytokines. In animal models, supplementation with rhu-pGSN both prevented and mitigated DCS-related complications.
This randomized, double-blind, placebo-controlled study will enroll healthy trained SCUBA divers at a single site and expose them to a standardized hyperbaric protocol (30 meters of seawater for 35 minutes). Participants will be randomized into three groups to receive either pre-exposure or post-exposure rhu-pGSN, or placebo. The study will assess a broad range of outcomes including plasma gelsolin levels, inflammatory markers like IL-1β, gas bubble formation, and well-being metrics.
Dr. Thom states, 'If successful, this study could transform the way we manage decompression sickness by providing a portable, field-deployable treatment option. Reducing our reliance on hyperbaric chambers would greatly expand our ability to treat DCS in remote or operational environments, improving outcomes and readiness, a key goal for the Navy.' BioAegis and University of Maryland are co-applicants on a patent filing listing Dr. Thom as an inventor.
Gelsolin: A Multitasking Protein for Complex Inflammatory Conditions
Rhu-pGSN holds immense promise as a therapeutic intervention for serious acute and chronic conditions due to its multifaceted mechanism of action. In critical illness, gelsolin levels collapse, causing adverse outcomes. Supplementing gelsolin addresses this deficit directly, restoring immune balance while preserving host defense and rhu-pGSN has been shown in animal studies to:
Supplementation with the recombinant gelsolin protein holds promise to address the overzealous inflammatory response associated many inflammatory diseases without suppressing immune function.
