VBI Vaccines Inc. (Nasdaq: VBIV) (VBI), a commercial-stage biopharmaceutical company developing next-generation infectious disease and immuno-oncology vaccines, today reported financial results for the third quarter ending September 30, 2020 and provided a corporate update.

Jeff Baxter, VBI’s President and CEO commented: “Global knowledge and understanding of the COVID-19 pandemic continue to evolve, including with respect to correlate and durability of protection and the mutation potential of the virus. It is clear that an effective solution will need to both control the ongoing pandemic and provide long-term, sustainable protection. In the third quarter of 2020, we announced exciting preclinical immunologic data for our coronavirus vaccine program including that our trivalent candidate, VBI-2901, demonstrated broadened reactivity to a seasonal coronavirus not expressed in the vaccine, supporting the belief that VBI-2901 could offer potential protection from mutated strains of COVID-19 that may emerge over time. Vaccines continue to be a vital public health intervention, and we are resolute in our drive to be part of the solution for numerous unmet medical needs. The upcoming regulatory approval submissions for Sci-B-Vac®, our 3-antigen hepatitis B vaccine, are on-track to begin in Q4 2020, and we expect clinical data from both our therapeutic hepatitis B and glioblastoma programs later this year. To support our mission and activity, we are in a strong financial position with $120 million in cash and short-term investments, in addition to the contribution from the Canadian Government of up to CAD$56 million for our coronavirus program.”

Recent Highlights and Upcoming Program Milestones

Sci-B-Vac ® : 3-Antigen Prophylactic HBV Vaccine

• August and October 2020: Presentations of Phase 3 data at The Digital International Liver Congress™ 2020 (ILC), the Annual Meeting of the European Association for the Study of the Liver (EASL), and at ID Week 2020™. Multiple oral and e-poster presentations highlighted:
  • High serum levels of HBV surface antibodies (anti-HBs) titers :
    • Sci-B-Vac induced higher Geometric Mean Concentrations (GMC) of anti-HBs titers than Engerix-B in all subjects across both recently completed Phase 3 registrational studies, PROTECT and CONSTANT, regardless of age, gender, or underlying comorbidity
    • Persistence and durability of protective titers are believed to be dependent upon peak levels induced
  • Rapid onset of seroprotection in adults age 18-45:
    • Sci-B-Vac was able to induce high seroprotection rates (SPR) after both two and three doses of vaccine compared to Engerix-B
    • In the four controlled Phase 3 studies referenced, including the recently-completed pivotal PROTECT and CONSTANT studies, Sci-B-Vac achieved seroprotection rates (SPR) of 87.2-100.0% after two doses compared to 39.0-89.4% for Engerix-B
  • Safety : No new or unexpected safety signals were observed in either the PROTECT or CONSTANT study, and safety and tolerability remained consistent with the known profile of Sci-B-Vac
• Q4 2020: Submissions of applications for regulatory approvals in the U.S., Europe, and Canada expected to begin

VBI-2900: Prophylactic Coronavirus Vaccine Program

• August 2020: Announcement of pre-clinical data from three mouse studies enabling the selection of two clinical vaccine candidates: (1) VBI-2901, a trivalent pan-coronavirus vaccine targeting SARS-CoV-2, SARS-CoV, and MERS-CoV; and (2) VBI-2902, a monovalent coronavirus vaccine targeting SARS-CoV-2. Data highlights include:
  • Both vaccine candidates have the potential to be one-dose vaccines : After a single dose, VBI’s enveloped virus-like particle (eVLP) candidates expressing a modified, stabilized, pre-fusion form of the SARS-CoV-2 spike protein induced a neutralizing antibody (nAb) geometric mean titer (GMT) 4x higher than that induced by convalescent sera, increasing to 64x higher than high-titer convalescent sera after the second dose
  • Trivalent construct increased breadth of reactivity : VBI-2901 further induced antibody binding titers across each of the three expressed spike proteins and also broadened reactivity to HCoV-OC43, a seasonal circulating coronavirus associated with the common cold that was not expressed in the vaccine
• August 2020: Agreement announced with Therapure Biomanufacturing, an integrated Contract Development Manufacturing Organization (CDMO), for development and manufacturing services for production of coronavirus vaccine candidates
• Around Year-End 2020: Initiation of initial adaptive Phase 1/2 human clinical study expected, pending regulatory approvals

VBI-1901: Cancer Vaccine Immunotherapeutic Candidate

• September 2020: Additional biomarker data presented at the European Society for Medical Oncology (ESMO) Virtual Congress 2020, highlighting:
  • Evaluation of human leukocyte antigen (HLA) restriction and T cell receptor (TCR) repertoires
  • Broadened analysis of the six tumor responders seen to-date, including a partial response, in the study continues to build upon potentially predictive biomarker strategy to help identify glioblastoma (GBM) patients most likely to respond to, and benefit from, treatment with VBI-1901
• Q4 2020: Initial immunologic and tumor response data expected from the Phase 2a VBI-1901 + AS01 B study arm
• Results observed to-date support further clinical development – exploring potential registrational study, expected to initiate in 2021

VBI-2601 (BRII-179): HBV Immunotherapeutic Candidate

• Q4 2020: Initial human proof-of-concept data expected from ongoing Phase 1b/2a study conducted in chronically-infected hepatitis B patients, in collaboration with Brii Biosciences

Third Quarter 2020 Financial Results

• Cash Position: VBI ended the third quarter of 2020 with $120.4 million in cash, cash equivalents, and short-term investments compared to $44.2 million as of December 31, 2019.
• Net Cash Used in Operating Activities: Net cash used in operations for the nine months ended September 30, 2020 was $30.6 million compared to the $40.2 million for the same period in 2019. The decrease is largely the result of the completion of the Sci-B-Vac Phase 3 clinical studies, the first of which (PROTECT) was completed in June 2019, the second of which (CONSTANT) was completed in January 2020.
• Cash Used for Purchase of Property and Equipment: Cash used for the purchase of property and equipment for the nine months ended September 30, 2020 was $0.5 million compared to $3.5 million for the same period in 2019. The decrease was due to the completion of the modernization and capacity increase of VBI’s manufacturing facility in Rehovot, Israel, which re-commenced operations in May 2019.
• Revenue: Revenue in the third quarter of 2020 was $0.3 million compared to $0.6 million for the same period in 2019. The decrease was due to a decrease in product revenue of Sci-B-Vac in Israel and a decrease in supply of product on a named-patient basis in Europe during the three months ended September 30, 2020 compared to the three months ended September 30, 2019. The decrease was also related to a decrease in R&D services revenue for VBI-2601, as manufacturing and non-clinical research services completed as part of the ongoing collaboration with Brii Biosciences.
• Cost of Revenues: Cost of revenues for the third quarter of 2020 was $2.1 million, comparable to $2.0 million for the same period in 2019.
• Research and Development (R&D): R&D expenses were $4.5 million for the third quarter of 2020, compared to $5.4 million for the same period in 2019. The decrease in R&D expenses is the result of the completion of the Sci-B-Vac pivotal Phase 3 studies.
• General and Administrative (G&A): G&A expenses for the third quarter of 2020 were $5.6 million, compared to $9.4 million for the same period in 2019. The decrease is a result of the impairment charge relating to goodwill incurred in the third quarter of 2019 that did not reoccur in the third quarter of 2020. This was offset by an increase in pre-commercialization activities for Sci-B-Vac as well as an increase in insurance costs.
• Net Loss: Net loss and net loss per share for the third quarter of 2020 were $13.0 million and $0.06, respectively, compared to a net loss of $16.2 million and a net loss per share of $0.15 for the third quarter of 2019.
