"2018 was a foundational year, one that laid critical groundwork as we build towards the transformational milestones expected in 2019," said Jeff Baxter, President and CEO, VBI Vaccines Inc. "Our achievements in 2018 – which included the launch of the collaboration with Brii Biosciences to develop a functional cure for Hepatitis B for up to $129 million plus royalties, the closing of a $42.9 million public offering led by Perceptive Advisors, the positive Phase 1 data readout from our cytomegalovirus (CMV) vaccine candidate, and encouraging early immunogenicity data from the Phase 1/2a of our glioblastoma (GBM) immuno-therapeutic – set the stage for 2019. Heading into this year, VBI is well-positioned to achieve meaningful clinical milestones across all of our lead programs, most notably the top-line data readout from the PROTECT Phase 3 study of Sci-B-Vac expected in four months’ time."

Sci-B-Vac Program Update (Prophylactic Hepatitis B):

In December 2017, the Company initiated enrollment in two pivotal Phase 3 clinical studies – PROTECT and CONSTANT – in a total of approximately 4,500 adults. The studies were designed to assess safety and efficacy of Sci-B-Vac, VBI’s prophylactic hepatitis B (HBV) vaccine that is the only commercially-available trivalent HBV vaccines containing Pre-S1, Pre-S2, and S antigens and adjuvanted with alum.

"Hepatitis B remains a serious public health unmet need, one where enhanced protection through vaccination is vital for long-term control," said Francisco Diaz-Mitoma, M.D., Ph.D., VBI’s Chief Medical Officer. "In the last two decades, Sci-B-Vac has been tested in 22 different clinical trials and has been safely and effectively administered to over 500,000 infants and adults in the commercial setting. We believe the extensive safety and efficacy data we have to-date has largely de-risked the ongoing Phase 3 studies. We look forward to the data readouts later this year, as we work to provide a rapid, potent, and safe hepatitis B vaccine to address this significant unmet infectious disease need."

Upcoming Sci-B-Vac Clinical Data Read-outs:

●Mid-year 2019: PROTECT Phase 3 top-line data

PROTECT is a head-to-head immunogenicity study in approximately 1,600 subjects comparing Sci-B-Vac to Engerix-B.
Primary endpoints include non-inferiority of Sci-B-Vac in adults over age 18, and superiority of Sci-B-Vac in adults over age 45.
Secondary endpoints include non-inferiority of Sci-B-Vac after two vaccinations compared with three vaccinations of Engerix-B, and safety.

●Around year-end 2019: CONSTANT Phase 3 top-line data

CONSTANT is a lot-to-lot consistency study in approximately 2,850 subjects comparing immune responses across three independent, consecutively manufactured lots of Sci-B-Vac.
Secondary endpoints include safety, and efficacy compared with Engerix-B

Other Pipeline Program Updates:

GBM Immuno-therapeutic:

VBI-1901, an immuno-therapy developed using VBI’s proprietary enveloped virus-like particle (eVLP) technology platform, is being assessed in an ongoing phase 1/2a clinical study in recurrent GBM patients. In 2018, VBI completed enrollment in all three dose cohorts in the Part A dose-escalation phase of the study, with six patients enrolled in each cohort. In February 2019, the independent Data and Safety Monitoring Board (DSMB) reviewed all safety data from Part A and unanimously recommended the continuation of the study without modification.

"While Part A of the study was primarily designed to assess safety and tolerability of VBI-1901 to support the identification of the optimal therapeutic dose level for Part B of the study, we are encouraged by the early immunogenicity data we’ve observed to-date," said David Anderson, Ph.D., VBI’s Chief Scientific Officer. "Part B of the study will have narrower enrollment criteria and is primarily designed to assess efficacy signals of VBI-1901 in recurrent GBM patients. With a more homogenous patient cohort in Part B, we look forward to identifying potential initial correlations between immunologic responses and clinical outcomes by year-end 2019."

Upon selection of the optimal dose level in Part A, based on safety and immunogenicity data, the Company expects to initiate enrollment of an additional 10 patients in the subsequent Part B extension phase of the study. Expanded immunologic data and 6-month survival data from all dose cohorts in the Part A dose-escalation phase are expected later in the first half of 2019.

Hepatitis B Immuno-therapeutic:

In December 2018, VBI announced a license and collaboration agreement with Brii Biosciences, for up to $129 million plus royalties, for the development of a functional cure for the treatment of chronic hepatitis B infection using VBI-2601. VBI-2601 is a novel immuno-therapeutic candidate that is uniquely formulated to target B- and T-cell immunity by neutralizing circulation of the hepatitis B virus, blocking hepatitis B infection of hepatocytes through Pre-S1 immunity, and enabling immune-mediated clearance of HBV-infected hepatocytes.

As part of this collaboration, clinical proof of concept studies are expected to be initiated by the end of 2019.

CMV Prophylactic Vaccine:

In May 2018, VBI announced positive top-line data from the Phase 1 study of VBI-1501, the Company’s prophylactic vaccine candidate for CMV. The Phase 1 top-line data showed that VBI-1501 was safe and well-tolerated at all doses and was immunogenic, even at the lower doses tested. In December 2018, VBI announced plans for a formal Phase 2 dose-ranging study to assess safety and immunogenicity of VBI-1501 at higher doses. The highest dose level is expected to be 10-times higher than that tested in the Phase 1 study.

The Company expects to initiate enrollment in the Phase 2 study by the end of 2019, following the requisite toxicology studies.

Financial Results for the Three and Twelve Months Ended December 2018:

○VBI ended the fourth quarter of 2018 with $59.3 million cash and cash equivalents compared with $67.7 million as of December 31, 2017. Net cash used in operating activities for the full year 2018 was $45.5 million, compared to $31.4 million for the same period in 2017. Additionally, the purchase of property and equipment in 2018 was $6.0 million compared with $0.6 million in 2017. This increase was due to the modernization and capacity increase of the Rehovot site, where all clinical and commercial supplies of Sci-B-Vac are manufactured, to enable the supply of commercial quantities of Sci-B-Vac upon marketing authorization approval by the FDA, EMA, and/or Health Canada. As part of this modernization and capacity increase, the site was temporarily shut down as of April 22, 2018. The construction related to the modernization and capacity increase is ongoing, and validation activities are in progress.

○Revenue for the fourth quarter of 2018 was $2.7 million, and was primarily attributable to amounts recognized as part the therapeutic Hepatitis B license and collaboration agreement with Brii Biosciences. Revenue for the fourth quarter of 2017 was $0.2 million and was primarily attributable to sales of Sci-B-Vac in Israel. Product sales in 2018 were $0.6 million compared with $0.5 million in 2017. The change was due to an increase in product sales related to the Sci-B-Vac named-patient program in Europe, offset by a slight decrease in Sci-B-Vac sales in Hong Kong and Israel.

○Cost of Revenue for the full year 2018 was $4.5 million compared with $5.2 million for the full year 2017. This decrease was due to the Rehovot site shut-down, resulting in limited production activity, reduced maintenance and utilities expenses, and allocation of some overhead to general and administrative expenses.

○Research and development expenses for the fourth quarter and full year 2018 were $10.1 million and $38.5 million, respectively. Research and development expenses for the same periods in 2017 were $6.5 million and $20.9 million, respectively. The increase was driven by the initiation and execution of the two Sci-B-Vac Phase 3 trials and the GBM Phase 1/2a clinical trial, which are currently ongoing.

○General and administrative expenses for the fourth quarter and full year 2018 were $9.9 million and $20.8 million, respectively. General and administrative expenses for the same periods in 2017 were $3.4 million and $12.0 million, respectively. The increase was primarily attributable to a $6 million payment made in December 2018 to re-obtain a distribution agreement with a third party who previously held certain distribution rights to certain Asian markets.

○Net loss and net loss per share for the year-end 2018 were $63.6 million and $0.97, respectively, compared to a net loss of $39.0 million and a net loss per share of $0.88 for the year-end 2017

Results for the Transition Period Ended December 31, 2018

On December 14, 2018, the Company’s Board of Directors approved a change in the Company’s fiscal year end from June 30 to December 31, effective immediately. The reporting period for the six months ended December 31, 2018 is referred to as the "Transition Period."

The Company had no revenues in the Transition Period due primarily to the discontinued sale of LeukoScan during the quarter ended March 31, 2018 in order for the Company to focus on its ADC business. Revenues in the comparable period ended December 31, 2017 were approximately $1.3 million.

Total costs and expenses were $144.5 million for the Transition Period, compared to $52.3 million for the comparable period ended December 31, 2017, due primarily to a $51.1 million increase in research and development expenses, a $23.3 million increase in general and administrative expenses, and a $18.4 million increase in sales and marketing expenses. Most of these increases were attributable to activities related to preparations for the potential approval and commercial launch of sacituzumab govitecan for patients with at least two prior lines of treatment for metastatic TNBC in the United States, and to expanded clinical development of sacituzumab govitecan into other indications.

The Company recognized a $1.4 million non-cash income for the Transition Period, compared to a $59.6 million non-cash expense for the comparable period ended December 31, 2017, due to the net appreciation in the fair value of outstanding warrants and the exercise of warrants. There were no warrants outstanding as of December 31, 2018.

Interest expense was $20.0 million for the Transition Period, compared to $2.9 million for the comparable period ended December 31, 2017. The increase was due primarily to increased debt balances as a result of the agreement with RPI Finance Trust.

Net loss attributable to stockholders was $157.7 million, or $0.84 per share, for the Transition Period, compared to $121.3 million, or $0.88 per share, for the comparable period ended December 31, 2017.

As of December 31, 2018, the Company had $497.8 million in cash, cash equivalents, and marketable securities, which it believes is adequate to support its clinical development plan for sacituzumab govitecan; further build its clinical and manufacturing infrastructure and fund its operations through 2020.

On February 25, 2019 Cellectis (Euronext Growth: ALCLS; Nasdaq: CLLS), a biopharmaceutical company focused on developing immunotherapies based on allogeneic gene edited CAR T-cells (UCART), reported the publication of a study in The Journal of Biological Chemistry, identifying Granulocyte Macrophage Colony Stimulating Factor (GMCSF) secreted by Chimeric Antigen Receptor (CAR) T-cells as a key factor promoting cytokine release syndrome (CRS) (Press release, Cellectis, FEB 25, 2019, View Source [SID1234533710]). The accelerated report leverages these findings to elaborate an innovative engineering strategy that paves the way for developing safer UCART products.

Utilizing these results, Cellectis developed engineered GMCSF Knock-Out CAR T-cells through TALEN-mediated gene inactivation. The inactivation of GMCSF in CAR T-cells was found to prevent secretion of pro-inflammatory cytokines by monocytes, without compromising CAR T-cell anti-tumor activity.

"CAR T-cells have achieved high rates of complete remission in hematological malignancies, however, this ‘living drug’ can show life-threatening inflammatory side effects including CRS and neurotoxicity that need to be addressed," said Mohit Sachdeva, Ph.D., Innovation Project Leader at Cellectis. "Our engineering strategy circumvents such toxic side effects and propose safer, equally potent UCART-cells, to improve patients’ quality of life during treatment."

"Today, tocilizumab or glucocorticoid treatments are considered the standard of care for CRS management," added Julien Valton, Ph.D., Innovation Team Leader at Cellectis. "However, these treatments increase patient medication burden, add substantial costs and lengthen treatment time in intense care settings. To overcome these clinical challenges, we investigated the biogenesis of CRS and based on our findings, developed a CAR T-cell product candidate that could potentially prevent rather than treat CRS symptoms. We hope this approach can bypass CRS symptomatic treatments and improve the overall safety of CAR T-cell therapies for cancer patients."

Julien Valton, Ph.D., Innovation Team Leader, Cellular Engineering & Adoptive CAR T-Cell Immunotherapy

Dr. Julien Valton obtained his Ph.D. at the University Joseph Fourier in Grenoble, France, where he was trained as an enzymologist. He then joined the Yale School of Medicine to apply his knowledge to therapeutic research by investigating the mechanism of inhibition of receptor tyrosine kinases that are involved in the development of gastrointestinal cancer. In 2009, he moved a step further into the field of applied science by joining the Innovation Department of Cellectis, where he actively participated in using and improving TALEN gene editing technology for targeted gene therapy and genome engineering. He is now using TALEN along with protein engineering techniques to develop the next-generation CAR T-cells to treat different malignancies.

Mohit Sachdeva, Ph.D., Innovation Team Senior Scientist

Dr. Sachdeva is an experienced cancer biologist with expertise in immuno-oncology, having authored/co-authored approximately 20 manuscripts in peer-reviewed journals throughout his career. During his time at Cellectis, he has been studying pathways that could be exploited to engineer potent, yet safer, CAR T-cells using gene editing and targeted integration technologies. After receiving his Ph.D. at Southern Illinois University, he completed a successful post-doc at Duke University.
