NANTES, France, Sept. 21, 2021 (GLOBE NEWSWIRE) -- OSE Immunotherapeutics (ISIN: FR0012127173; Mnémo: OSE) today reported its consolidated half-year financial results as of June 30, 2021 and provided updates on key milestones achieved during H1 2021.

Alexis Peyroles, CEO of OSE Immunotherapeutics, commented: “The first half of 2021 was marked by major clinical advances with promising data readouts on one hand and the initiation of new clinical trials on the other. We also secured additional non-dilutive financial resources to continue investing in our R&D drug discovery engine which has continued to identify novel therapeutics for patients with high medical need in immuno-oncology and autoimmune indications.

The positive final results of the Tedopi® Phase 3 trial in non-small cell lung cancer patients in secondary resistance to ICIs presented at the recent ESMO conference include promising clinical benefit and good safety profile, and will support our discussions with the FDA and EMA on the best regulatory paths and next steps toward a potential approval. In parallel, the scope of Tedopi® is being broadened through two sponsored studies, one in combination with a PD-1 inhibitor in NSCLC for patients in secondary resistance to checkpoints inhibitors and another in ovarian cancer.

The first part of 2021 has also established OSE Immunotherapeutics as one of the key players in the promising CD47 space in solid tumors. Encouraging data with SIRPa inhibitor BI 765063 in combination with anti-PD-1 BI 754091, which were presented at ASCO and ESMO, support moving forward with the Phase 1 expansion trial to demonstrate the relevance of the combination approach as a potential therapeutic strategy in solid tumors.

OSE remains a partner of choice for pharma companies and we concluded a new license agreement with Veloxis, a leading transplantation company, to develop, manufacture and commercialize FR104 for all transplant indications.

We also strengthened our cash position through upfront and milestone payments from our pharma partners, public fundings and financing from the European Investment Bank received in July 2021, extending our cash position to Q3 2022.”

Clinical results and advances in immuno-oncology and autoimmune diseases

Tedopi®, a neoepitope-based vaccine to induce specific T-lymphocyte activation: Positive final results for Phase 3 clinical trial in non-small cell lung cancer (NSCLC); initiation of two Phase 2 clinical trials in combination with an immune checkpoint inhibitor

  • Positive final results from the 'Atalante-1' Phase 3 study of Tedopi®
    These results were presented at the 2021 ESMO (European Society for Medical Oncology) conference on September 20th. The data have shown statistical improvement in overall survival, favorable benefit/risk ratio and a good quality of life in NSCLC patients after secondary resistance to immune checkpoint inhibitors. Based on the promising clinical benefit and good safety profile, OSE Immunotherapeutics plans to continue discussing with the FDA and EMA about the optimal regulatory paths and next steps to register Tedopi® in both territories and evaluate how these positive results can support this objective.

  • In May, initiation of Phase 2 in NSCLC, sponsored and conducted by the Italian oncology Foundation FoRT
    This study will evaluate Tedopi® in combination with immune checkpoint inhibitor Opdivo® (nivolumab), or Tedopi® plus chemotherapy or chemotherapy alone as second-line treatment in patients with metastatic NSCLC after first-line chemo-immunotherapy.

  • In August, first patient randomized in the ‘TEDOVA’ Phase 2 in ovarian cancer, sponsored and conducted by the cooperative oncology group ARCAGY-GINECO
    This trial will evaluate Tedopi® as a maintenance treatment, alone or in combination with anti-PD-1 immune checkpoint inhibitor Keytruda® (pembrolizumab), versus best supportive care in patients with first or second platinum-sensitive recurrent ovarian cancer with controlled disease after platinum-based chemotherapy and who have already received both bevacizumab and a PARP (Poly ADP-Ribose Polymerase) inhibitor.

  • Ongoing ‘TEDOPaM’ Phase 2 in pancreatic cancer, sponsored by the cooperative oncology group GERCOR
    Due to the COVID-19 pandemic, accrual of new patients had been temporarily suspended in March 2020. After reviewing data collected until the end of March 2020 and based on the initial protocol (Tedopi® in combination with Opdivo® or alone versus chemotherapy with FOLFIRI), the trial’s independent committee of scientific experts (IDMC, “Independent Data Monitoring Committee”) recommended stopping the evaluation of treatment with Opdivo® in combination with Tedopi® and to integrate the chemotherapy (FOLFIRI) in combination with Tedopi®. The new inclusions resumed in Q2 2021 with an amended protocol comparing Tedopi® in combination with FOLFIRI chemotherapy versus FOLFIRI, after treatment with FOLFIRINOX.

BI 765063 (OSE-172), a myeloid checkpoint inhibitor being developed in partnership with Boehringer Ingelheim: Promising data from the dose escalation of the Phase 1 clinical trial

  • Data from the dose escalation (Step 1) of the Phase 1 trial were presented at ASCO (June 2021) and ESMO (September 2021) and indicated that BI 765063 in monotherapy or in combination with anti-PD-1 BI 745091 (ezabenlimab) was well tolerated and showed promising clinical activity, including one partial response in monotherapy and three partial responses in combination in heavily pre-treated advanced solid tumor patients.

OSE-127/S95011, a monoclonal antibody antagonist of the interleukin-7 (IL-7) receptor, developed in partnership with Servier: Initiation of a Phase 2 in Sjögren’s syndrome (sponsored by Servier) and a Phase 2 clinical trial in ulcerative colitis (sponsored by OSE)

  • In January, the Company received a €1.3 million milestone payment from Bpifrance related to the collaborative program EFFIMab, focused on developing the clinical asset OSE-127/S95011.

  • In August, the first patient was enrolled in a Phase 2 trial evaluating the efficacy and safety of OSE-127/S95011 in Sjögren’s syndrome, sponsored by Servier.

  • As part of the partnership agreement, this first patient enrolled in the Sjögren’s syndrome Phase 2 triggered a €5 million milestone payment from Servier to OSE Immunotherapeutics,.

  • In parallel, a Phase 2 in ulcerative colitis is being conducted under OSE sponsorship. First patient was enrolled at the end of 2020 and data are expected in H2 2022.

FR104, a monoclonal antibody antagonist of CD28: Licensing agreement with Veloxis in transplantation

  • In April, OSE announced a global license agreement granting Veloxis Pharmaceuticals worldwide rights to develop, manufacture and commercialize FR104 for all transplant indications. Under this agreement, OSE can receive up to €315 million in potential milestones, including a €7 million upfront, and tiered royalties on sales. OSE retains the rights in autoimmune indications.

  • FR104 is being evaluated in a Phase 1/2 trial initiated in December 2020 in patients undergoing renal transplant. This study is conducted as part of a collaboration agreement between OSE Immunotherapeutics and the University Hospital of Nantes, the sponsor.

CoVepiT, a 2nd generation multi-target vaccine against COVID-19, developed using SARS-CoV-2 optimized epitopes: Initiation of Phase 1/2 clinical trial followed by a voluntary and temporary pause in enrollment

  • In April, OSE initiated a Phase 1/2 clinical trial to evaluate the safety and immunogenicity of CoVepiT vaccine in 48 healthy adult volunteers.

  • In July, the trial’s principal investigator reported a limited number of Grade 1 and one Grade 2 adverse events, in particular, persistent nodules around the injection sites. Out of an abundance of caution, and in agreement with the independent Safety Monitoring Committee (SMC), the Company decided to voluntarily pause dosing and assess the evolution of these nodules before determining the best way forward for this product and its target population. The Company is carefully reviewing all available data to determine the future clinical development strategy of CoVepiT.

New data reflecting progress on 3 early-stage programs developed in immuno-oncology and inflammation presented at the 2021 AACR meeting (American Association of Cancer Research)

New myeloid checkpoint target CLEC-1 (a C type lectin receptor) and first monoclonal antibody antagonists of CLEC-1 blocking the “Don’t Eat Me” signal

  • Data generated to date illustrate that CLEC-1 broadly inhibits tumor-cell phagocytosis and synergizes with tumor-targeted cytotoxic monoclonal antibodies in both solid and hematological tumors and hampers dendritic cell antigen cross-presentation.

BiCKI®-IL-7, a novel bispecific therapy combining anti-PD-1 and the cytokine IL-7

  • Data presented to date validate the strong therapeutic potential of providing IL-7 signals to strengthen PD-1 therapy and prevent immuno-resistance by sustaining T cell response and overcoming Treg suppression. The bispecific BiCKI® IL-7 mutein can preferentially deliver and activate the IL-7 pathway on tumor reactive T cells, limiting the risk of immunotoxicity resulting from combination immunotherapies.

OSE-230, novel monoclonal antibody agonist therapy triggering resolution of chronic iInflammation

  • An article published in Science Advances is the first peer-reviewed publication to describe an agonist monoclonal antibody (OSE-230) that triggers pro-resolutive mechanisms in macrophages and neutrophils in chronic inflammatory condition. This breakthrough discovery opens the development pathway of OSE-230 in various chronic inflammations such as inflammatory bowel diseases, arthritis, type 1 diabetes, lung or kidney inflammatory diseases. Moreover, the data presented at the AACR meeting revealed for the first time a therapeutic potential of triggering the pro-resolutive pathways using anti-ChemR23 agonistic monoclonal antibodies to limit chronic inflammation in the tumor microenvironment and inhibit metastasis development.

OSE Immunotherapeutics will host an “Immuno-oncology R&D Day”
on October 12, 2021 (16:00 – 19:00 CET).
The event will be hybrid with virtual and in-person presentations held in Paris.
In this event, the company will highlight its leading scientific role in immuno-oncology and emerging
proprietary portfolio, and provide a more in-depth look at lead projects, Tedopi® and BI 765063
