VBI Vaccines : Presents Early GBM Tumor Response and Immunologic Data from Part B of Ongoing Phase 1/2a Study of VBI-1901 at the 2019 SNO Annual Meeting

'The clinical outcomes from Part A, the tumor responses we've seen in three of the six patients in the high-dose cohort in Part A, and now again the tumor response seen in one of the two patients enrolled and evaluable to-date in Part B continue to be encouraging,' said David E. Anderson, Ph.D., VBI's Chief Scientific Officer. 'In an effort to better understand these early tumor response data, we are also characterizing baseline biomarkers and immunologic responses, notably T cell responses. Correlations between immunological biomarkers and tumor/clinical responses will be refined as more patients are enrolled in Part B of the study.'

To-date, the ongoing Phase 1/2a open-label multicenter study has enrolled all 18 recurrent GBM patients in Part A of the study and four first-recurrent GBM patients in Part B. As of the cut-off date of November 18, 2019, of the four patients enrolled in Part B of the study, two were evaluable for immunologic responses, and one was evaluable for tumor response.
