Non-Hodgkin lymphoma (NHL) is an umbrella term for a group of cancers that develop in the body’s lymphatic system. Examples of sub-indications are patients with Mantle Cell Lymphoma (MCL), Follicular Lymphoma (FL) and Marginal Zone Lymphoma (MZL). Examples of subindications are patients with Mantle Cell Lymphoma, Follicular Lymphoma, and Marginal Zone Lymphoma. Aggressive lymphomas are usually treated with combinations of various chemotherapeutic agents and monoclonal anti-bodies such as rituximab (Rituxan®, Mabthera®, Roche). Low-grade lymphomas have a better prognosis and treatment is often only initiated once a patient has disease symptoms.
TB-403 in paediatric brain tumours
- development in collaboration with Oncurious
TB-403 is currently in a Phase I/II study for the treatment of patients with medulloblastoma in cooperation with a US based pediatric oncology network, Beat Childhood Cancer. The study progresses according to plan, and the fourth dose level is ongoing. Initial data from this study are anticipated towards the end of 2019.
TB-403 has received Orphan Designation for medulloblastoma from the European Medicines Agency (EMA). TB-403 is developed in collaboration with Oncurious, a subsidiary of Oxurion (formerly known as ThromboGenics). BioInvent’s ownership in TB-403 is 50 percent and it contributes with 50 percent of the development costs.
Patents for TB-403 and similar antibodies have been granted in Europe, the US, Japan and several additional countries, and patent applications are pending in further countries. Patents covering use of antibodies against PIGF, for example for the purpose of treating or preventing cancer, have also been granted, including in the US.
THR-317 in diabetic macular edema
- under development by Oxurion
THR-317 is in a phase ll study evaluating the efficacy and safety of intravitreal THR-317 when administered in combination with ranibizumab (Lucentis®), for the treatment of Diabetic Macular Edema. Recruitment of this study is completed, and results are according to Oxurion expected in early Q3 2019. In addition, THR-317 is evaluated in a Phase ll study for the treatment of Idiopathic Macular Telangiectasia Type 1 (MacTel 1), a rare disease that affects the macula and can lead to vision loss. First data from this study are according to Oxurion expected towards the end of 2019.
Patents for the antibody have been granted in Europe, the US, Japan and several additional countries, and patent applications are pending in further countries.
Developing antibodies that act on regulatory T cells (Tregs) via novel or validated targets
Tregs can substantially inhibit various immune responses, enabling tumor cells to escape detection. BioInvent is utilizing its F.I.R.S.T™ platform to identify and characterize monoclonal antibodies to cancer-associated Treg targets in a function-first, target-agnostic, manner. The Company is also pursuing differentiated antibodies to known targets through novel mechanisms and pathways.
BioInvent has identified TNFR2, a member of the so called TNFR superfamily (TNFRS) as a target within the Treg program. The Company has antibody candidates with various mechanisms of action that show promising preclinical data. The most advanced candidate is BI-1808 and a first clinical study is scheduled for H1 2020.
Partnership with Transgene – developing next generation oncolytic viruses expressing an anti-CTLA-4 antibody to treat solid tumours
BioInvent and Transgene collaborate to co-develop oncolytic virus (OV) candidates encoding a validated anti-CTLA-4 antibody sequence - potentially with additional transgenes - aimed at treating solid tumors.
Transgene is contributing both its OV design and engineering expertise, as well as its proprietary Vaccinia viruses, designed to directly and selectively destroy cancer cells by intracellular replication of the virus in the cancer cell (oncolysis). Oncolysis induces an immune response against tumors, while the “weaponized” virus allows the expression of genes carried by the oncolytic viral genome, such as an immune modulatory anti-CTLA-4 antibody, to further boost immune response against the tumor.
BioInvent is providing its cancer biology and antibody expertise to the collaboration, as well as anti-CTLA-4 antibody sequences generated through its proprietary n-CoDeR®/F.I.R.S.TTM platforms.
This novel OV product has the potential to be significantly more effective than the combination of single agents. Transgene has generated preclinical proof-of-concept data showing that an oncolytic vaccinia virus encoded with a checkpoint inhibitor resulted in better overall survival than the corresponding combination of separate single agents.
In March 2019 BioInvent and Transgene announced an extension of their collaboration to co-develop multi-functional oncolytic viruses encoding antibodies targeting an undisclosed target, which can be used in the treatment of a broad range of solid tumors.
The research and development costs, as well as revenue and royalties from candidates generated from the collaboration, will be shared 50:50
Strategic collaboration with Pfizer - developing antibodies that act on tumour-associated myeloid cells
In partnership with Pfizer Inc. since December 2016, BioInvent works to identify novel oncology targets and therapeutic antibodies that may either reverse the immunosuppressive activity of tumor-associated myeloid cells or reduce the number of tumor-associated myeloid cells in the tumor. To date, pools of antibodies have been generated and are being characterized for functional activity.
BioInvent is eligible for potential future development milestones in excess of $500 million (assuming five antibodies are developed through to commercialization). The Company could also receive up to double digit royalties related to product sales. In exchange, Pfizer will have the right to develop and commercialize any antibodies generated from this agreement.
BioInvent received an upfront payment of $3 million when the agreement was signed in December 2016, and research funding has been received during 2017 and 2018. Pfizer also made a $6 million equity investment in new shares of BioInvent when the agreement was signed.
