Navrogen Inc. | August 18, 2021
Navrogen Inc. a biopharmaceutical company specialized in developing therapies for cancer and immune-related disorders, and Tavotek Biotherapeutics, a biotech company focusing on novel multi-specific antibodies in immuno-oncology and autoimmune diseases, announced today that they have entered into a strategic collaboration to identify and develop experimental monoclonal antibodies (mAbs) for the treatment of various cancer indications.
Under the agreement, Navrogen and Tavotek will collaborate on the development of future Tavotek oncology assets while utilizing Navrogen's proprietary screening technology to identify mAb leads that are susceptible to Humoral Immuno-Oncology (HIO) factors. HIO is a process by which tumors produce factors that suppress a patient's humoral immune response against malignant tissues as well as diminish therapeutic response of immune-mediated anti-cancer therapies. Working with Navrogen's HIO platform technologies and its expertise in patient tumor screening methods, the teams will identify and/or engineer HIO-refractory antibodies that are effective across a wide range of HIO-positive cancers leading to innovative treatment options for patients with limited therapeutic options.
About Navrogen™ Inc
Navrogen is a biopharmaceutical company focused on the discovery of tumor-produced Humoral Immuno-Oncology (HIO) factors that are associated with suppressed humoral immunity, poor prognosis and limited therapeutic response of immune-mediated anti-cancer therapies. The company's mission is to develop first-in-class agents that can overcome the immunosuppressive effects of HIO factors by employing its proprietary screening and engineering technologies as well as diagnostic assays that can identify patients whose tumors produce HIO factors to advise physicians on therapeutic options.
About Tavotek Biotherapeutics
Tavotek is a biopharmaceutical company focused on discovering, acquiring, developing, and commercializing therapeutic medicines for patients suffering from debilitating diseases with significant unmet medical needs. Tavotek has a rich pipeline of product candidates at various stages of development for cancer, autoimmune conditions, and inflammatory diseases.
Acticor Biotech | October 05, 2020
Acticor Biotech, a clinical stage biotechnology company involved in the acute phase of thrombotic diseases, including acute ischemic stroke, today announced the completion of its ACTIMIS Dose Escalation Phase of Glenzocimab Study as add-on to standard of care in Patients with acute ischemic stroke. This Dose Escalation Phase was successfully completed with 60 patients enrolled from 6 European countries (France, Belgium, Germany, Spain, Switzerland and Italy). 5 cohorts of patients presenting with an acute ischemic stroke episode of moderate to severe intensity were enrolled in this study and randomly received glenzocimab at one of 4 ascending doses or a placebo, in a blind fashion as a 6-hour single-dose infusion. Patients were evaluated continuously for 24 hours, then 7 and 90 days after the episode. Approximately 50% were also treated with the thrombolytic agent rtPA (ACTILYSE®), and the other 50% received rtPA and underwent a mechanical thrombectomy. The DSMB met on 5 occasions in between each cohort and at the end of the last administration, and they analyzed the safety data with a particular focus on the advent of intra-cerebral hemorrhages and other bleeding related events. The last analysis performed after the target dose of 1000mg had been administered to 12 patients confirmed both the absence of increased bleeding when glenzocimab is added to rtPA and to rtPA and thrombectomy, and the absence of any dose-related trend in the number and nature of adverse events recorded.

Valneva SE, IDT Biologika | November 30, 2021
Valneva SE, a specialty vaccine company, and IDT Biologika announced their collaboration for the production of Valneva’s inactivated COVID-19 vaccine candidate VLA2001. This follows last week’s announcement that Valneva signed an Advance Purchase Agreement with the European Commission to supply up to 60 million doses of VLA2001, over two years.
Under the collaboration, IDT Biologika will produce VLA2001’s drug substance at its Biosafety Level 3 facilities in Dessau-Roßlau, Germany, in addition to Valneva’s manufacturing site in Livingston, Scotland.
“IDT is a well-established partner within Valneva’s manufacturing network. As such we are extremely pleased to extend this partnership to supply VLA2001. This collaboration will help ensure our inactivated vaccine is available for rapid deployment as we continue to believe that our differentiated vaccine candidate can make an important contribution to the global fight against the COVID-19 pandemic.”
Thomas Lingelbach, Chief Executive Officer of Valneva
Dr. Jürgen Betzing, Chief Executive Officer of IDT Biologika, added, “This is great news for our company. This assignment shows the importance of the role played by IDT in the fight against COVID-19. It is a great achievement and demonstrates the trust that Valneva has placed in us and our employees. The expansion of our production capacity combined with our expertise were key factors in the choice of IDT.”
Valneva has continued to review its manufacturing strategy following discussions with the UK Government in the summer and again after the termination of the UK contract in September 2021. Valneva plans to operate a combination of external and internal production of VLA2001 and will further review its manufacturing plans based on demand. The Company’s sites in Livingston, Scotland and Solna, Sweden will continue to form part of the Company’s core manufacturing strategy.
Valneva reported positive Phase 3 results for VLA2001 in October 20211. Delivery of the vaccine in Europe is currently expected to begin in April 2022, subject to approval by the European Medicines Agency which is expected to start a rolling review of VLA2001 shortly.
VLA2001 is currently the only whole virus, inactivated, adjuvanted vaccine candidate against COVID-19 in clinical trials in Europe. It is intended for active immunization of at-risk populations to prevent carriage and symptomatic infection with COVID-19 during the ongoing pandemic and potentially later for routine vaccination including addressing new variants. VLA2001 may also be suited for boosting, as repeat booster vaccinations have been shown to work well with whole virus inactivated vaccines. VLA2001 is produced on Valneva’s established Vero-cell platform, leveraging the manufacturing technology for Valneva’s licensed Japanese encephalitis vaccine, IXIARO®. VLA2001 consists of inactivated whole virus particles of SARS-CoV-2 with high S-protein density, in combination with two adjuvants, alum and CpG 1018. This adjuvant combination has consistently induced higher antibody levels in preclinical experiments than alum-only formulations and shown a shift of the immune response towards Th1. CpG 1018 adjuvant, supplied by Dynavax Technologies Corporation (Nasdaq: DVAX), is a component of the US FDA- and EMA-approved HEPLISAV-B® vaccine. The manufacturing process for VLA2001, which has already been upscaled to final industrial scale, includes chemical inactivation to preserve the native structure of the S-protein. VLA2001 is expected to conform with standard cold chain requirements.
