OSE Immunotherapeutics and Nantes University Hospital Present Positive Phase 1/2 Study Evaluating FR104/VEL-101 Immunotherapy in Renal Transplant
At the American Transplant Congress 2024 (June 1-5 Philadelphia)
Nantes, France – June 5, 2024, 7:30am CET – OSE Immunotherapeutics SA (ISIN: FR0012127173; Mnemo: OSE) and Nantes University Hospital present positive Phase 1/2 analysis from first use of anti-CD28 FR104/VEL-101 in kidney transplantation in oral presentation at the Annual American Transplant Congress (ATC) held in Philadelphia (June 1-5, 2024). A total of three oral presentations on FR104/VEL-101 were presented at this congress.
A first oral communication, entitled “First use of FR104, an anti-CD28 molecule in human kidney transplantation”, presented by Pr. Gilles Blancho, Head of the ITUN* at the University Hospital in Nantes / Nantes University and Principal Investigator of the study, reported on the positive data from the completed Phase 1/2 clinical trial FIRsT evaluating FR104/VEL-101 in patients undergoing renal allotransplant. This study is sponsored and conducted by the University Hospital of Nantes as part of a collaboration agreement with OSE Immunotherapeutics.
A second oral communication, entitled “Safety, Pharmacokinetics (PK), and Pharmacodynamics (PD) of Fixed-Dose, Subcutaneous (SQ) Administration of VEL-101, an Anti-CD28 Pegylated Monoclonal Antibody Fragment, in Healthy Participants”, presented by OSE Immunotherapeutics partner Veloxis Pharmaceuticals, featured the results from the Company’s Phase 1 dose escalation clinical trial evaluating the safety, tolerability, pharmacodynamics and pharmacokinetics of single ascending doses of subcutaneous administration of FR104/VEL-101 in healthy participants.
A third oral communication, entitled “Combined blockade of the CD154 and CD28 co-stimulation pathways attenuates pathogenic alloimmunity and prolongs survival in cynomolgus cardiac allografts”, presented by the group of Pr. Richard Pierson (Massachusetts General Hospital, Harvard university, Boston, USA), reported on the positive preclinical efficacy data of FR104/VEL-101 injection in monotherapy or in combination with anti-CD40L antibody to protect from acute and chronic heart allograft rejection.
Nicolas Poirier, Chief Executive Officer of OSE Immunotherapeutics, said: “We thank the University Hospital of Nantes for this important step with the first clinical study evaluating FR104/VEL-101 in transplanted patients. Our partner Veloxis presented its positive subcutaneous Phase 1 clinical trial results in oral session, which will facilitate dose selection in preparation for a Phase 2 study in kidney transplant recipients. At last, we are excited about the promising preclinical results of our academic collaborator in the field of cardiac transplantation, further enhancing the future market potential.”
Pr. Gilles Blancho commented: « We are very pleased to share the positive results of the FIRsT study at international congress on post-transplant immune response and one-year safety in patients treated with FR104/VEL-101, developed for years in our own research laboratory, CR2TI**/UMR Inserm 1064. The data presented show the safety of the product used in combination and the first signs of efficacy in kidney transplant recipients with no episodes of acute rejection after one year follow-up in all patients of the study. The exploration of FR104/VEL-101’s safety profile seems promising and encourages moving to a Phase 2 trial for patients undergoing renal transplant who require innovative solution.”
The purpose of the FIRsT Phase 1/2 clinical trial is to investigate the safety, tolerability, and pharmacokinetics of FR104/VEL-101, a novel antagonist pegylated anti-CD28 Fab’ antibody fragment, as well as its potential clinical efficacy on acute rejection prophylaxis and renal function in a de novo renal transplant population receiving an allograft from standard criteria donors (NCT number: NCT04837092). A one-year safety and efficacy of FR-104/VEL-101 treatment assessment was performed after transplantation, including renal function, incidence of rejection and suspected reported adverse events.
Ten patient candidates eligible to a first kidney transplant at low risk of rejection, as planned in the protocol, have been included in the FIRsT study for eight analyzable patients (two patients were screened and enrolled but not transplanted for technical reasons). Tacrolimus (a calcineurin inhibitor) was withdrawn after 6 months post-transplantation. The eight patients completed 1-year treatment with FR104/VEL-101.
No safety alert was detected for FR104/VEL-101. Adverse events were those conventionally observed in kidney transplantation. Pharmacological monitoring made it possible to optimize exposure to FR104/VEL-101 and to maintain high receptor occupancy during the one-year follow-up. With a follow-up of 1 year in all patients, not only no acute rejection under FR104/VEL-101 was observed, and notably no acute rejection episodes occurred after discontinuation of tacrolimus, but also no immunization against the donor occurred. One of the key challenges in organ transplantation remains calcineurin inhibitors alternatives with effective immunosuppressive treatments and minimal side effects, particularly on renal function in order to preserve patients’ quality of life, and long-term control of post-transplant immune reaction.

FR104/VEL-101 is a pegylated monoclonal antibody fragment that binds to and blocks CD28-mediated effector-T cell co-stimulation, without blocking CTLA-4, an important protein receptor found on T cells that acts as a natural brake on the body’s immune responses. FR104/VEL-101 is, therefore, expected to have a dual-mechanism of action where in a direct manner, it blocks CD28-mediated T cell activation, and in an indirect way, it allows for CTLA-4 mediated immunosuppressive functions.
