LPOXY Therapeutics Secures $28M Financing to Combat C. difficile Infections

LPOXY Therapeutics, Inc., a clinical-stage biopharmaceutical enterprise, has taken a significant step in developing a groundbreaking approach to combat Clostridioides difficile infections (Cdiff) by initiating a $28 million Series A financing round. This funding, facilitated by the venture capital firm 5 Horizons Ventures, is earmarked to support the registrational STOP-Cdiff trial, otherwise known as the SIDIPREV™ Trial On Prevention of C. difficile Infections.

Addressing a Critical Health Concern

C. difficile infections are a pressing health hazard, with the Centers for Disease Control and Prevention (CDC) categorizing it as an urgent public health threat. Alarmingly, around 80 Americans succumb to this infection every day. Currently, there are no approved preventive therapies available, showcasing a substantial unmet need within the healthcare landscape. LPOXY's SIDIPREV™ aims to fill this void with an innovative, non-antibiotic treatment.

SIDIPREV™ represents a transformative approach in infection prevention. This oral, enteric-coated capsule liberates a metered dose of oxygen in the lower gastrointestinal tract, creating an inhospitable environment for anaerobic pathogens such as C. difficile. The therapeutic effects of oxygen also extend to inhibiting toxin production and exerting mucosal anti-inflammatory effects, potentially revolutionizing how healthcare addresses C. difficile risk.

The Pivotal STOP-Cdiff Trial

The upcoming STOP-Cdiff trial, expected to commence in the third quarter of 2026, is pivotal for LPOXY. Planned as a randomized, placebo-controlled superiority study, it aims to evaluate the safety and efficacy of SIDIPREV™ in approximately 500 hospitalized patients who are at heightened risk for C. difficile infections. These patients often include the elderly and those who have recently been exposed to antibiotics. LPOXY's goal is to submit regulatory filings for SIDIPREV™ by 2029.

CEO Dr. Larry Sutton articulated the significance of this new funding, stating, "5 Horizons Ventures' commitment marks a major milestone for LPOXY as we move toward launching our pivotal STOP-Cdiff trial. SIDIPREV™ represents a novel approach to infection prevention that addresses a deadly unmet need while aligning with the economics of hospital care by mitigating costly complications associated with C. difficile infections."

Commitment from Investors

The carrying of this trial reflects strong investor confidence, as Paul Ferguson, Partner and CFO of 5 Horizons Ventures, expressed admiration for LPOXY’s team and strategy. He pointed out that SIDIPREV™ has the potential to escape the reimbursement and resistance challenges that conventional antibiotics often encounter, presenting a rare opportunity for stakeholders to unlock genuine economic value for patients and hospitals.

By building an investment syndicate, LPOXY is in discussions with various other institutional investors who share its vision for a late-stage clinical strategy to combat C. difficile effectively.

The success of this trial could herald a new era in the prevention of C. difficile infections, consequently saving lives and enhancing the overall quality of healthcare.

Given its promising results and innovative approach, SIDIPREV™ could redefine the standards of care in a field marked by dire needs and limited options. Only time will tell if this clinical initiative will reach its ambitious milestones, but the commitment from both the company and its investors paints a hopeful picture for the future of infection prevention.
