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 that its abstract highlighting additional biomarker data from the ongoing Phase 1/2a study of VBI-1901, the company’s cancer vaccine immunotherapeutic candidate, in recurrent glioblastoma (GBM) patients was selected for an e-poster presentation at The European Society for Medical Oncology (ESMO) Virtual Congress 2020.
Title: TCR and HLA analysis of patients in a Phase I/IIa trial of a therapeutic CMV vaccine against recurrent glioblastoma (GBM)
Abstract #: 4112
Date/Time: Thursday, September 17, 2020 – Monday, September 21, 2020
About the Phase 1/2a Study Design
VBI’s 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:
Phase 1 (Part A)
- Dose-escalation phase that defined the safety, tolerability, and optimal dose level of VBI-1901 adjuvanted with granulocyte-macrophage colony-stimulating factor (GM-CSF) in recurrent GBM patients with any number of prior recurrences.
- This phase enrolled 18 recurrent GBM patients across three dose cohorts of VBI-1901: 0.4 µg, 2.0 µg, and 10.0 µg.
- Enrollment completed in December 2018.
Phase 2a (Part B)
- Subsequent extension of the optimal dose level, 10.0 µg, as defined in the Part A dose escalation phase.
- This phase is a two-arm study, enrolling 10 first-recurrent GBM patients in each arm, assessing 10.0 µg of VBI-1901 in combination with either GM-CSF or GSK’s proprietary AS01B adjuvant system as immunomodulatory adjuvants.
- Enrollment of the 10 patients in the GM-CSF arm is complete. Enrollment of the 10 patients in the AS01B arm is ongoing.
VBI-1901 is administered intradermally when adjuvanted with GM-CSF and intramuscularly when adjuvanted with the AS01B 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 VBI’s 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 is exceptionally lethal.
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: (1) the only tri-antigenic 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 (2) an immunotherapeutic in development for a functional cure for chronic hepatitis B. VBI’s enveloped virus-like particle (eVLP) platform technology enables development of eVLPs that closely mimic the target virus to elicit a potent immune response. VBI’s lead eVLP programs include a vaccine immunotherapeutic candidate targeting glioblastoma (GBM), a prophylactic cytomegalovirus (CMV) vaccine candidate, and a prophylactic pan-coronavirus vaccine candidate. VBI is headquartered in Cambridge, MA, with research operations in Ottawa, Canada, and research and manufacturing facilities in Rehovot, Israel.
