"The last few months have seen meaningful progress across our portfolio, marked by achievements in our Sci-B-Vac Phase 3 studies, PROTECT and CONSTANT, and early data from our Phase 1/2a study of VBI-1901 in recurrent glioblastoma (GBM)," said Jeff Baxter, President and CEO. "We have now completed vaccination and enrollment in the PROTECT and CONSTANT studies, respectively, with an exceptionally low drop-out rate, and no safety signals observed or reported to-date. These accomplishments support the clean safety profile of Sci-B-Vac and reaffirm the timeline for top-line data from the PROTECT and CONSTANT trials, expected to read out mid-year 2019 and around the 2019 year-end, respectively."

Mr. Baxter continued, "Additionally, we are encouraged by the early immunologic data we’ve seen from our Phase 1/2a study of VBI-1901 in recurrent glioblastoma (GBM), which has shown evidence of robust boosting of CMV-specific immunity in some subjects in both the low-dose and intermediate-dose cohorts. With the addition of two top neuro-oncology sites, Dana-Farber Cancer Institute and Massachusetts General Hospital, we expect to complete enrollment in the high-dose cohort quickly. Thanks to the dedication and achievements of the entire VBI team, the fundamentals of the company remain strong and on-track as we head into a critical and exciting first half of 2019."

Recent Highlights and Upcoming Milestones

Formation of Three Scientific and Clinical Advisory Boards

● In September, VBI announced the creation of three Scientific and Clinical Advisory Boards (SABs) comprised of leading global experts in immunology and vaccinology. The SABs will work closely with VBI’s management team to develop and advance the Company’s hepatitis B, cytomegalovirus (CMV), and glioblastoma (GBM) vaccine programs.

Appointment of Chief Financial Officer and Head of Business Development

● In August, VBI appointed Christopher McNulty as Chief Financial Officer and Head of Business Development, bringing with him a strong background in licensing transactions, capital markets and financing strategy, and public company corporate finance in the biopharmaceutical and medical device fields.

Sci-B-Vac for Hepatitis B

● The Company’s prophylactic Hepatitis B vaccine, Sci-B-Vac, is currently being evaluated in a global, pivotal Phase 3 clinical program, the results of which are intended to support future regulatory and marketing authorization submissions in the U.S., Europe, and Canada. The program consists of two concurrent Phase 3 studies:
● PROTECT Study: A head-to-head immunogenicity study against Engerix-B.

○ In October, VBI announced completion of vaccination, with the last subject receiving the final vaccination.
○ Patients in the PROTECT study were vaccinated with a low drop-out rate of 4.5%, reinforcing the safety and tolerability of the vaccine.
○ The independent Data and Safety Monitoring Board (DSMB) reviewed all PROTECT safety data available to-date and did not observe or report any safety signals.
○ Top-line data from the PROTECT study are expected mid-year 2019.
● CONSTANT Study: A lot-to-lot consistency study.
○ VBI completed enrollment in the CONSTANT study, with the last subject receiving the first vaccination in November.
○ Top-line data from the CONSTANT study are expected around the 2019 year-end.

VBI-1901 for Glioblastoma (GBM)

● The Phase 1/2a study of VBI-1901 in recurrent GBM is ongoing, with early immunologic data to be presented in a poster discussion at the Annual Scientific Meeting and Education Day of the Society for Neuro-Oncology (SNO) on November 16, 2018.
○ Early data from the low- and intermediate-dose cohorts of VBI-1901 are encouraging, with robust boosting of CMV-specific immunity, directed against multiple antigens, observed in some subjects in both cohorts.
○ In September 2018, VBI announced that the DSMB unanimously recommended continuation of the study without modification after review of all safety data from the fully-enrolled, intermediate-dose patient cohort.
○ Following the DSMB recommendation, VBI initiated patient enrollment in the high-dose cohort of Part A of the study, the dose-escalation phase.
○ VBI expects to complete enrollment in the high-dose study arm later in 2018, at which point a final, pre-specified DSMB review will occur before initiation of enrollment in Part B of the Phase 1/2a study.
○ VBI expects to report more extensive immunologic data and 6-month overall survival and progression-free survival from all dose cohorts in Part A of the Phase 1/2a in the first half of 2019.

VBI-1501 for Congenital Cytomegalovirus (CMV)

● Following the positive safety and immunogenicity data from the Phase 1 randomized, observer-blind, placebo-controlled study evaluating the safety and immunogenicity of VBI-1501 in May 2018, discussions are ongoing with regulatory bodies to determine the design of a Phase 2 dose-ranging study.
● Further details are expected to be announced by the end of 2018.

Third Quarter 2018 Financial Results

○ VBI ended the third quarter of 2018 with $26.0 million in cash and cash equivalents compared with $67.7 million as of December 31, 2017. Net cash used in operations for the nine months ended September 30, 2018 was $38.0 million.

○ Revenue for the third quarter of 2018 was $0.26 million and was primarily attributable to sales of Sci-B-Vac in Israel and in Europe on a named-patient basis. Revenue for the third quarter of 2017 was $0.19 million and was primarily attributable to sales of Sci-B-Vac in Israel.

○ Research and development expenses were $10.5 million for the third quarter of 2018, as compared to $5.2 million for the same period in 2017. The increase was primarily due to the continuation of the Phase 3 program for Sci-B-Vac and the Phase 1/2a clinical study for VBI-1901 in recurrent GBM patients.

○ General and administrative expenses were $3.5 million for the third quarter of 2018 as compared to $2.8 million for the same period in 2017. The increase was primarily due to allocation of expenses from costs of revenues related to the modernization and capacity increases of our manufacturing facility in Rehovot, Israel, human resources expenses, and stock-based compensation expenses.

○ Net loss and net loss per share for the third quarter of 2018 were $15.4 million and $0.24 respectively, compared to a net loss of $9.8 million and a net loss per share of $0.24 for the third quarter of 2017.

On November 9, 2018 Synthorx, Inc., a biotechnology company using a first-of-its-kind Expanded Genetic Alphabet platform technology to discover and develop optimized biologics for cancer and autoimmune disorders, reported company researchers will present results of preclinical studies demonstrating the safety and anti-tumor effects of its lead product candidate THOR-707, a "not-alpha" Synthorin of interleukin-2 (IL-2), for the treatment of solid tumors at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 33rd Annual Meeting (Press release, Synthorx, NOV 9, 2018, View Source [SID1234531204]).

The study, titled "THOR-707: An engineered IL-2 for the treatment of solid tumors with superior preclinical efficacy and safety evidence," investigates the application of Synthorx’s Expanded Genetic Alphabet platform technology to engineer THOR-707, a variant of recombinant human IL-2 that is pegylated at one specific site and designed to kill tumor cells without inducing vascular leak syndrome (VLS), a toxicity associated with aldesleukin, an approved recombinant IL-2. Aldesleukin was approved by the U.S. Food and Drug Administration over 25 years ago for the treatment of patients with metastatic renal cell carcinoma and metastatic melanoma. However, widespread use of aldesleukin has been limited by toxicities, which include life-threatening and sometimes fatal VLS, as well as by its short half-life, requiring courses of dosing of three times per day over eight days.

In Synthorx’s preclinical studies, THOR-707 induces molecular markers of T cell activation and the proliferation of peripheral NK and CD8+ effector T cells in vivo. However, dosing of THOR-707 has minimal effect on molecular and clinical markers of VLS, even at high exposures. Analysis of the effect of THOR-707 in syngeneic mouse tumor models showed that THOR-707 induced infiltration of CD8+ T effector cells into tumors and elicited anti-tumor effects alone and in combination with a PD-1 immune checkpoint inhibitor.

"Our team has executed extremely well over the past quarter, rapidly enrolling multiple clinical trials and presenting impressive clinical and preclinical data for both of our programs. We are excited about the potential for our DKN-01 antibody in patients with esophagogastric cancer, both in combination with KEYTRUDA (pembrolizumab) and with paclitaxel. We believe that the emerging response and disease control rates, and now the progression-free survival and overall survival data, reflect outcomes that are clinically meaningful to patients with very difficult to treat cancer and are greater than what has previously been demonstrated with approved single agents," commented Christopher K. Mirabelli, Ph.D, President and Chief Executive Officer of Leap Therapeutics. "In addition, we look forward to presenting data from the studies of our TRX518 antibody in combination with KEYTRUDA, OPDIVO (nivolumab) or gemcitabine at the European Society for Molecular Oncology 2018 Immuno-Oncology Congress in December."

Recent Developments

Since the end of the second quarter, the Company has continued to make strong progress with the development of their product candidates.

DKN-01/KEYTRUDA: At the European Society for Molecular Oncology (ESMO) (Free ESMO Whitepaper) 2018 Annual Congress, Leap presented clinical data from a study evaluating DKN-01 in combination with KEYTRUDA (pembrolizumab) in patients with advanced esophagogastric cancer. As of the cut-off date for the poster, DKN-01 and pembrolizumab had a 23.5% overall response rate and 58.8% disease control rate in evaluable gastric or gastroesophageal junction cancer patients who have been heavily pre-treated and not received any prior anti-PD-1/PD-L1 therapy. All four of the responding patients had tumors that were microsatellite stable, which is a subgroup of patients who have historically experienced a less than ten percent response rate to KEYTRUDA monotherapy.

DKN-01/PACLITAXEL: At the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 33rd Annual Meeting, Leap presented an update on a clinical study evaluating DKN-01 in combination with paclitaxel in patients with advanced esophagogastric cancer. The combination of DKN-01 and paclitaxel generated a 46.7% overall response rate, 19.6 weeks median progression free survival, and 61.1 weeks median overall survival in fifteen evaluable patients as a second line therapy. In the benchmark RAINBOW study, paclitaxel monotherapy in second line gastroesophageal junction or gastric cancer patients generated a 16.1% overall response rate, 2.9 months median progression free survival, and 7.4 months median overall survival. Additionally, in our study in the subgroup of twelve evaluable patients with heavily pre-treated esophageal squamous cell carcinoma, the combination of DKN-01 and paclitaxel produced a 33.3% overall response rate, 13.7 weeks median progression free survival, and 31.0 weeks median overall survival.

DKN-01 in HCC: The first patient has been enrolled in Leap’s investigator-initiated study of DKN-01 as a monotherapy and in combination with NEXAVAR (sorafenib) in hepatocellular carcinoma patients with Wnt pathway activation.

TRX518/BAVENCIO: In July, Leap announced a collaboration agreement with Pfizer and Merck KGaA, Darmstadt, Germany to evaluate TRX518 in combination with BAVENCIO (avelumab) and cyclophosphamide chemotherapy. Under the terms of the collaboration, Leap will be conducting a Phase I/II clinical trial in advanced solid tumors including expansion populations in patients with relapsed/refractory ovarian, breast, and prostate cancers.

· TRX518/KEYTRUDA or OPDIVO or GEMCITABINE: During the third quarter, Leap presented initial data from a clinical trial evaluating TRX518 in combination with gemcitabine chemotherapy or in combination with KEYTRUDA (pembrolizumab) or OPDIVO (nivolumab). Three patients treated with TRX518 in combination with anti-PD1 antibodies have experienced clinical benefit. An esophageal squamous cell carcinoma patient treated with TRX518 and KEYTRUDA demonstrated a partial response with a 77% reduction in tumor volume, and an ocular melanoma patient experienced stable disease with a 23% reduction in tumor volume. An urothelial carcinoma patient who had progressed while on KEYTRUDA has had a partial response with TRX518 and OPDIVO with a 39% reduction in tumor volume. We have also fully enrolled the TRX518 and gemcitabine expansion cohort. We plan to present additional data from this trial at the ESMO (Free ESMO Whitepaper) Immuno-Oncology Congress in December 2018.

Selected Third Quarter 2018 Financial Results

Net loss was $6.6 million for the third quarter of 2018, compared to $6.8 million for the same period in 2017.

Research and development expenses were $6.5 million for the third quarter 2018, compared to $6.8 million for the same period in 2017. The decrease of $0.3 million was primarily due to a decrease of $1.3 million in manufacturing costs related to clinical trial material. This decrease was partially offset by an increase of $0.7 million in clinical trial costs, an increase of $0.2 million in payroll and other related costs and an increase of $0.1 million in stock based compensation expense.

General and administrative expenses were $2.1 million for the third quarter 2018, compared to $1.8 million for the same period in 2017. The increase of $0.3 million in general and administrative expenses was primarily due to a $0.2 million increase in stock based compensation expense and an increase of $0.1 million in legal, audit and consulting fees associated with corporate and business development activities.

Cash, cash equivalents and marketable securities totaled $23.2 million at September 30, 2018. Research and development incentive receivables totaled $2.1 million. In October 2018, we received $0.8 million of research and development tax incentive payments from the Commonwealth of Australia. We anticipate that our current cash resources will extend until late in the third quarter of 2019.

On November 9, 2018 Alligator Bioscience (Nasdaq Stockholm: ATORX), a biotechnology company that develops antibody-based drug candidates for tumor-directed immunotherapy and Aptevo Therapeutics Inc. (Nasdaq: APVO), a biotechnology company that develops new treatments in immunology and hematology, reported that new preclinical data for ALG.APV-527 will be presented at the 33rd Annual Meeting of the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper)’s (SITC) (Free SITC Whitepaper) Scientific Conference, held in Washington, DC, USA, November 9-11, 2018 (Press release, Alligator Bioscience, NOV 9, 2018, View Source [SID1234531196]).

ALG.APV-527 is a drug candidate for immunotherapeutic treatment of 5T4 positive solid cancer tumors. It is designed to activate the immune system via the co-stimulating receptor 4-1BB (CD137) on activated cytotoxic T cells and NK (Natural Killer) cells. ALG. APV-527 is designed to induce a powerful and tumor-directed immunoreactivation in the presence of 5T4 positive tumor cells. 5T4 is a tumor antigen found in a variety of malignant tumor types.

Preclinical data show that ALG.APV-527 is located in 5T4 positive tumors and selectively stimulates and enhances tumor-responsive immune responses of T cells and NKs, providing powerful anti-tumor effects. In brief, the preclinical data shows that ALG.APV-527 in the presence of 5T4 positive cells:

Increases the ability of CD8 positive T cells to secrete pro-inflammatory cytokines such as IFN gamma
Strengthens NK cell’s cell killability
In addition, the new data confirm that the 5T4 antigen is found in a variety of tumor types. 5T4 positive tumor cells were detected in non-small cell lung cancer (NSCLC) tumor, head and neck cancer, mesothelioma, pancreatic, bladder, kidney and ovarian cancer, but not in normal tissue samples such as liver and heart.

"Recent preclinical results further enhance ALG.APV-527’s potential for targeting 5T4 positive tumors and selectively activating the immune system via tumor-specific activation of T cells and NK cells. Overall, this gives potential for better anti-tumor effect with less side effects. We are now compiling a preclinical data packet with the goal of submitting a clinical trial (CTA) clinical trial in the second half of 2019, "said Christina Furebring, Senior Vice President Research at Alligator.

"Our new bispecific drug candidate ALG.APV-527 continues to show promising results in preclinical in vitro and in vivo studies. It exhibits properties such as goal-directed T-cell activation, optimized stability, an antibody-like half-life of 9 days, and good production characteristics. Aptevo and Alligator believe that this gives ALG.APV-527 a potential to become a unique anti-cancer drug for the treatment of several 5T4 expressive solid tumors, where there is today a major medical need. We are looking forward to submitting a CTA next year and then commencing clinical studies, "said Jane Gross, Chief Scientific Officer at Aptevo.

Alligator / Aptevos poster presentation titled "Potent Tumor-Directed T Cell Activation and Tumor Inhibition Induced by a 4-1BB x 5T4 ADAPTIR Bispecific Antibody " will be presented today November 9th from 18.45 to 14.45 (12.45-14.45 local) time) and from kl.30.30 to 2.30 (18.30-20.30 local time).

About ALG.APV-527
ALG.APV-527 is a bispecific antibody (4-1BB x 5T4) intended for tumor directed treatment of solid cancer tumors. ALG.APV-527 was constructed by combining Alligator’s antibody library ALLIGATOR-GOLD and Aptevo’s bispecific technology ADAPTIR . The antibody ALG.APV-527 consists of two parts, one activating tumor-specific T cells via the co-stimulating receptor 4-1BB (CD137) and the other binding to the protein 5T4 on the surface of tumor cells. This controls the immune activating effect of ALG.APV-527 to the tumor and not to normal tissue.
