- Independent Data and Safety Monitoring Board (DSMB) unanimously recommends continuation of study without modification
- Intermediate-dose study arm: enrollment complete
- Initial immunologic data from low and intermediate-dose cohorts expected in the fourth quarter 2018
VBI Vaccines Inc. (NASDAQ: VBIV) (“VBI”), a commercial-stage biopharmaceutical company developing next-generation infectious disease and immuno-oncology vaccines, today announced that the independent Data and Safety Monitoring Board (DSMB) completed its second safety assessment of the ongoing Phase 1/2a clinical study of VBI-1901 in recurrent GBM. The DSMB reviewed the complete safety data from the fully enrolled, intermediate-dose patient cohort, and unanimously recommended the continuation of the study without modification.
Following this recommendation, VBI has initiated enrollment in the high-dose arm of the study. One final, pre-specified DSMB review is expected to occur after completion of enrollment in the high-dose cohort, concluding the dose-escalation phase of the study.
“We are encouraged by the sustained clean safety profile of VBI-1901 as concluded by this second DSMB assessment,” said Jeff Baxter, VBI’s President and CEO. “These positive safety reviews are critical milestones for the program and for patients diagnosed with this extremely aggressive tumor who currently have no effective treatment options. With active clinical study sites at the Columbia University Medical Center, Dana-Farber Cancer Institute, and Massachusetts General Hospital, we hope to complete enrollment in this high-dose cohort quickly and look forward to announcing initial immunologic data from the low- and intermediate-dose cohorts expected later this year.”
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 to define the safety, tolerability, and optimal dose level of VBI-1901 in recurrent GBM patients. This phase is expected to enroll up to 18 patients in three dose cohorts.
- Part B: A subsequent extension of the optimal dose level, as defined in the dose escalation phase. This phase is expected to enroll an expanded cohort of approximately 10 additional 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 vaccine every four weeks until tumor progression.
