CAMBRIDGE, Mass., June 04, 2019 (GLOBE NEWSWIRE) -- VBI Vaccines Inc. (NASDAQ: VBIV) (“VBI”), a commercial-stage biopharmaceutical company developing next-generation infectious disease and immuno-oncology vaccines, presented a poster on Sunday, June 2, 2019, at the American Society of Clinical Oncology (ASCO) Annual Meeting that exhibited expanded clinical data from Part A of the Phase 1/2a study of VBI-1901 in recurrent Glioblastoma (GBM) patients.
The poster presented data on a total of 18 patients enrolled in Part A of the study, which was a multi-center, open-label, dose-escalation study across three dose cohorts of VBI’s vaccine immunotherapeutic, VBI-1901 – 0.4 µg, 2.0 µg, and 10.0 µg. Part A was designed to evaluate the safety and tolerability of VBI-1901, and to define the optimal immunogenic dose level to test in the Part B extension phase of the study, which is expected to initiate enrollment mid-year 2019. Part B of the trial will further assess immunologic responses and potential correlations with tumor and clinical responses.
Andrew B. Lassman, M.D., Chief of Neuro-oncology at Columbia University Irving Medical Center and Associate Director for Clinical Infrastructure at Herbert Irving Comprehensive Cancer Center, and principal investigator of the study commented, “Though early, the data we’ve seen to-date in this Phase 1/2a study of VBI-1901 are intriguing, yet of course require confirmation in later phase and additional trials. The patients in this study, and more generally in the recurrent GBM setting, are immunocompromised and have very few effective treatment options available to them. Any treatment that could demonstrate even some benefit would be incredibly meaningful for these patients and their families. I look forward to seeing additional data from Part B of the study.”
Highlights from Poster Presentation (Poster #237, Abstract #2048)
“The tumor responses seen in three of the six patients in the high-dose cohort are promising, with all three having immunologic responses to VBI-1901 as well,” said David E. Anderson, Ph.D., VBI’s Chief Scientific Officer. “In Part B of the study, we are narrowing the enrollment criteria to ensure a more homogenous patient population that may better assess the potential correlation between immunogenicity and tumor and clinical responses to VBI-1901. Enrollment of 10 patients in Part B, all first-recurrent GBM patients, is expected to initiate mid-year this year, 2019.”

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 28 patients with recurrent GBM:
VBI-1901 is administered intradermally and is adjuvanted with granulocyte-macrophage colony-stimulating factor (GM-CSF), a potent adjuvant that mobilizes dendritic cell function. Patients in both phases of the study will receive the vaccine immunotherapeutic every four weeks until tumor progression.
Additional information, including a detailed description of the study design, eligibility criteria, and investigator sites, is available at ClinicalTrials.gov using identifier NCT03382977.
