CAMBRIDGE, Mass.--(BUSINESS WIRE)--VBI Vaccines Inc. (Nasdaq: VBIV) ("VBI") a commercial-stage biopharmaceutical company developing next-generation infectious disease and immuno-oncology vaccines, today announced Phase 2a (Part B) data from its ongoing Phase 1/2a study of VBI-1901, the companys cancer vaccine immunotherapeutic candidate designed to target cytomegalovirus (CMV) as a foreign viral antigen in recurrent glioblastoma (GBM). The data were presented in an e-poster at the Society for Neuro-Oncology (SNO) 2020 Annual Meeting, November 19-21, 2020. Data from Phase 2a (Part B) of the ongoing study showed: Andrew B. Lassman, M.D., Chief of Neuro-oncology at Columbia University Irving Medical Center and Associate Director for Clinical Trials at the Herbert Irving Comprehensive Cancer Center, and principal investigator of the study presented the e-poster, commenting, Tumor response data is one of the most objective measures of efficacy in open label studies, especially in this difficult-to-treat patient population. Few treatment options are available to recurrent glioblastoma patients, and the tumor response data seen to-date in this ongoing study are encouraging. Any treatment that could demonstrate clinical benefit would be incredibly meaningful. Emmanuel Hanon, Senior Vice President, Head of R&D Vaccines at GSK, commented, The early data seen to-date in this ongoing study are encouraging, underscoring the potential benefit of adjuvants in combination with VBI-1901 in the clinical setting. Previous research in the context of other vaccines has shown AS01s ability to boost T cell-mediated immunity. This is the first time GSKs adjuvant system is assessed in oncology and we are looking forward to getting more data about the potential of therapeutic vaccination to treat such an aggressive and recurring disease. David E. Anderson, Ph.D., VBIs Chief Scientific Officer, commented, This ongoing study continues to demonstrate the potential of VBI-1901, with both the GM-CSF adjuvant and GSKs AS01 adjuvant system, to be an effective cancer vaccine immunotherapeutic. The tumor responses seen to-date across both study arms, including 2 partial responses and 7 stable disease, are meaningful, especially as an outcome of a monotherapy. This data supports the continued development of the program, both as a monotherapy as well as part of a combination regimen. Based on the available data, VBI is exploring a randomized, controlled clinical study, including a potential registration study, for the next phase of development, which could begin in 2021, pending approval from regulatory bodies. A webcast of Dr. Anderson discussing these data with Jeff Baxter, VBIs President and CEO, can be found here: https://www.vbivaccines.com/wire/vbi-1901-sno-2020-update/. A copy of the e-poster is available on the Events/Presentations page in the Investors section of the VBI Vaccines website. About the Phase 1/2a Study Design VBIs two-part Phase 1/2a study is a multi-center, open-label, dose-escalation study of VBI-1901 in up to 38 patients with recurrent GBM: VBI-1901 is administered intradermally when adjuvanted with GM-CSF and intramuscularly when adjuvanted with GSKs AS01 adjuvant system. Patients in both phases of the study receive the vaccine immunotherapeutic every four weeks until tumor progression. About VBI-1901 and GBM VBI-1901 is a novel cancer vaccine immunotherapeutic candidate developed using VBIs enveloped virus-like particle (eVLP) technology to target two highly immunogenic cytomegalovirus (CMV) antigens, gB and pp65. Scientific literature suggests CMV infection is prevalent in multiple solid tumors, including glioblastoma (GBM). GBM is among the most common and aggressive malignant primary brain tumors in humans. In the U.S. alone, 12,000 new cases are diagnosed each year. The current standard of care for treating GBM is surgical resection, followed by radiation and chemotherapy. Even with aggressive treatment, GBM progresses rapidly and has a high mortality. About VBI Vaccines Inc. VBI Vaccines Inc. (Nasdaq: VBIV) is a commercial-stage biopharmaceutical company developing a next generation of vaccines to address unmet needs in infectious disease and immuno-oncology. VBI is advancing the prevention and treatment of hepatitis B, with the only 3-antigen hepatitis B vaccine, Sci-B-Vac, which is approved for use and commercially available in Israel, and recently completed its Phase 3 program in the U.S., Europe, and Canada, and with an immunotherapeutic in development for a functional cure for chronic hepatitis B. VBIs enveloped virus-like particle (eVLP) platform technology enables development of eVLPs that closely mimic the target virus to elicit a potent immune response. VBIs lead eVLP programs include a vaccine immunotherapeutic candidate targeting glioblastoma (GBM), a prophylactic cytomegalovirus (CMV) vaccine candidate, and a prophylactic coronavirus vaccine program. VBI is headquartered in Cambridge, MA, with research operations in Ottawa, Canada, and research and manufacturing facilities in Rehovot, Israel.

Answer: VBI Vaccines Announces Positive Interim Phase 2a Data from VBI-1901 in Recurrent GBM - Interim data show promising disease control rates in patients vaccinated with VBI-1901 combined with the GM-CSF adjuvant (40%), and with VBI-1901 combined with GSKs adjuvant AS011 (56%) - 2 partial responses observed in VBI-1901 + GM-CSF study arm, with tumor reduction of more than 50%, and 7 stable disease observations across both vaccinated groups - VBI-1901 was well-tolerated with both adjuvants no safety signals observed in either vaccinated group
