— Part B of the study, a subsequent extension of the optimal dose from Part A, to enroll 10 first-recurrent GBM patients
— Initial immunologic data from Part B expected around year-end 2019
— Expanded immunologic data and tumor and clinical responses expected H1 2020
CAMBRIDGE, Mass., July 29, 2019 (GLOBE NEWSWIRE) -- VBI Vaccines Inc. (Nasdaq: VBIV) ("VBI"), a commercial-stage biopharmaceutical company developing next-generation infectious disease and immuno-oncology vaccines, today announced that the first patient has been dosed in Part B of the ongoing Phase 1/2a clinical study of VBI-1901, VBI’s oncology immunotherapeutic, in recurrent glioblastoma (GBM) patients.
“We were very encouraged by the results we saw in Part A of the study, notably that three out of the six patients in the high-dose cohort had evidence of stable disease by magnetic resonance imaging,” said David Anderson, Ph.D., VBI’s Chief Scientific Officer. “In part B of the study, we are narrowing the enrollment criteria to first-recurrent GBM patients so that we may better assess the potential correlation between immunogenicity and tumor and clinical responses to VBI-1901. GBM is an incredibly aggressive and devastating disease with very few treatment options, and we believe VBI-1901 has the potential to help address this tragic unmet medical need.”
The ongoing two-part study is a multi-center, open-label study conducted at The Neurological Institute of New York Columbia University Medical Center, Dana-Farber Cancer Institute, and Massachusetts General Hospital.
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:
- Part A:
— Dose-escalation phase that defined the safety, tolerability, and optimal dose level of VBI-1901 in recurrent GBM patients.
— This phase enrolled 18 recurrent GBM patients across three dose cohorts of VBI-1901: 0.4 µg, 2.0 µg, and 10.0µg. - Part B:
— Subsequent extension of the optimal dose level, 10.0 µg, as defined in the Part A dose escalation phase.
— This phase is expected to enroll an expanded cohort of approximately 10 additional first-recurrent GBM patients.
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.
