Tumor Responses in a Randomized Phase IIb Trial of a CMV Vaccine Immunotherapeutic Candidate (VBI-1901) in Recurrent Glioblastomas
(SNO 2024)
- P1/2 | "Approximately 60 adult subjects (18 years or older) with first recurrence of WHO 2016 grade IV Glioblastoma, IDH-wildtype will be randomized at a 1:1 ratio to two open-label cohorts to receive: VBI-1901 or standard of care (SOC) treatment with lomustine or carmustine. Among evaluable patients (n=13), disease control rates of 43% and 0% have been observed in the VBI-1901 and SOC arms, respectively, including 1 partial response in the VBI-1901 arm. Full enrollment (n=60) is anticipated by the end of the year across 11 sites, and updated tumor response data and select biomarkers associated previously with tumor responses will be presented."

As of January 31 st 2024 , 12 of 60 patients have been randomized and dosed across 8 US sites."

VBI Vaccines Presents Additional Biomarker Data from Phase 1/2a Study of VBI-1901 in Recurrent GBM at the 2023 Society for Neuro-Oncology (SNO) Annual Meeting
(Businesswire)
- P1/2a | N=98 | NCT03382977 | Sponsor: VBI Vaccines Inc. | "New proof-of-mechanism data demonstrated that vaccination with VBI-1901 was associated with T-cell activation capable of trafficking across the blood-brain barrier to the tumor microenvironment, an area which is known to be highly immunosuppressive and difficult to infiltrate....After vaccination with VBI-1901 in the Phase 1/2a study in recurrent GBM patients, the data showed there were higher blood/plasma levels of C4G in patients who achieved partial tumor responses than in patients with stable or progressive disease. Additionally, higher levels of C4G after vaccination with VBI-1901 have been associated with longer progression-free survival."

Peripheral Biomarker Analysis of T cell-mediated Collagen Remodeling Correlates with Tumor Responses in a Phase IIa trial of vaccine immunotherapeutic candidate (VBI-1901)
(SNO 2023)
- P1/2 | "The peripheral C4G biomarker targets granzyme-B-cleaved type IV collagen, which is associated with T cell infiltration and has previously been shown to potentially identify recurrent GBM patients responding to nivolumab and bevacizumab. Evaluating the balance of immune infiltration vs. tumor cell growth in patients with brain tumors is challenging and these data suggest a means of assessing this dynamic using a peripheral biomarker. These data may be particularly useful in discerning pseudoprogression associated with T cell infiltration from tumor progression."

Interim results of the extension phase of a Phase I/IIa trial of a therapeutic CMV vaccine against recurrent glioblastoma (GBM)
(SNO 2019)
- "Cytomegalovirus (CMV) antigens have been reported in over 90% of GBM tumors. CD4+and CD8+T cells are most frequently directed against the gB and pp65 antigens, respectively, and are immunogenic targets in a CMV-based GBM vaccine. We have initiated a phase I/IIa clinical trial for patients with recurrent GBM using gB/pp65 enveloped virus-like particles (eVLPs) formulated with GM-CSF and administered intradermally. In phase I, eligible patients were age 18-70 with Karnofsky Performance Status at least 70, normal end-organ function, on stable or decreasing corticosteroids of at most 4mg dexamethasone (or equivalent), with recurrent GBM following any standard initial therapy and any number of recurrences of any size. Patients were vaccinated monthly until tumor progression, with immune-monitoring performed 2 weeks after each vaccination and MRI exams every 6 weeks. The primary endpoint was safety/tolerability and secondarily to assess..."
