Pegrizeprument Market Summary

Key Factors Driving Pegrizeprument Growth

1. Significant Unmet Need in Solid Organ Transplantation

More than 150,000 solid organ transplants are performed globally each year, and recipients require lifelong immunosuppressive therapy to prevent graft rejection. Current calcineurin inhibitor (CNI)-based regimens, particularly tacrolimus, are highly effective but are associated with nephrotoxicity, metabolic complications, infections, malignancies, and chronic graft dysfunction. Pegrizeprument is being developed to provide effective immunosuppression while potentially reducing long-term toxicities, addressing a major unmet need in transplant medicine.

2. Novel CD28-Selective Mechanism Differentiates It from Existing Immunosuppressants

Pegrizeprument selectively blocks CD28-mediated T-cell co-stimulation while preserving CTLA-4 inhibitory signaling, unlike broader co-stimulation inhibitors. This dual mechanism is designed to suppress pathogenic T-cell activation while maintaining physiological immune regulation, potentially improving efficacy and safety. Preclinical non-human primate studies presented at the 2025 World Transplant Congress demonstrated prolonged rejection-free survival and reduced donor-specific antibody formation compared with conventional tacrolimus-based regimens, supporting its differentiated therapeutic profile.

3. Expansion Across Multiple Solid Organ Transplant Indications

Although the lead clinical program focuses on kidney transplantation, Veloxis is actively expanding development into liver and heart transplantation. In 2026, the U.S. FDA granted Orphan Drug Designation (ODD) for prevention of organ rejection following both liver transplantation and heart transplantation, broadening the future commercial opportunity beyond kidney recipients. These additional indications increase the potential addressable patient population while leveraging a common immunosuppressive mechanism.

4. Regulatory Incentives Reduce Development Risk

The FDA's Orphan Drug Designations for liver and heart transplant rejection provide important development and commercial incentives, including potential market exclusivity following approval, regulatory support, fee reductions, and enhanced interactions with the FDA. These incentives may accelerate development timelines and improve the product's competitive positioning in rare transplant settings.

5. Strong Strategic Partnership Supports Global Commercialization

Pegrizeprument was licensed by Veloxis from OSE Immunotherapeutics in 2021, with Veloxis obtaining worldwide rights to develop, manufacture, and commercialize the product for all transplant indications. Veloxis has an established global transplant franchise through products such as Envarsus XR, providing existing commercial infrastructure, transplant-center relationships, and clinical expertise that could facilitate rapid market adoption if pegrizeprument is approved.

Pegrizeprument Recent Developments

In April 2026, the FDA granted Orphan Drug Designation to pegrizeprument for the prevention of heart allograft rejection in heart transplant patients.

Pegrizeprument Drug Summary

Pegrizeprument (development codes VEL-101 and FR104) is an investigational pegylated, humanized monovalent anti-CD28 monoclonal antibody fragment (Fab) being developed by Veloxis Pharmaceuticals, under license from OSE Immunotherapeutics, for the prevention of acute organ rejection in solid organ transplant recipients. The drug selectively binds to the CD28 co-stimulatory receptor on T cells, blocking CD28-mediated effector T-cell activation while preserving the inhibitory CTLA-4 signaling pathway, thereby providing a more targeted immunomodulatory approach than conventional calcineurin inhibitors. This dual mechanism is designed to suppress alloreactive immune responses while maintaining physiological immune regulation, with the potential to reduce the nephrotoxicity, metabolic complications, and infection risk associated with existing long-term immunosuppressive regimens. Pegrizeprument is administered by intravenous infusion and is being evaluated as a maintenance immunosuppressive therapy for kidney, liver, and heart transplantation. The candidate has received U.S. FDA Orphan Drug Designation for the prevention of organ rejection following both liver and heart transplantation, underscoring its potential to address significant unmet needs in transplant medicine.
