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.

SITC 2018: further analyses of the Phase II study of the combination of monalizumab and cetuximab in head and neck patients show encouraging survival data in both subgroups of IO-naïve and IO-pretreated SCCHN patients

On November 12, 2018 Innate Pharma SA (the "Company" – Euronext Paris: FR0010331421 – IPH), reported exploratory subgroup analyses and preliminary translational data from the Phase II trial evaluating the combination of monalizumab and cetuximab (anti-EGFR) in previously treated patients with recurrent and/or metastatic squamous cell carcinoma of the head & neck (R/M SCCHN) (Press release, Innate Pharma, NOV 9, 2018, View Source [SID1234531226]). Monalizumab is a first-in-class checkpoint inhibitor targeting NKG2A inhibitory receptors expressed on tumor-infiltrating cytotoxic CD8 T lymphocytes and NK cells.

"The subgroup analysis revealed very interesting durable responses in both IO-naïve and IO-pretreated patients," commented Pierre Dodion, Chief Medical Officer of Innate Pharma. "Patients who have failed on IO-therapy currently have no other treatment option. The fact that they appear to benefit with prolonged survival is rather remarkable and prompted us to advance our clinical program. Discussions are taking place in parallel with regards to the next steps in IO naïve patients".

"The high disease control rate that we observed in this study along with the favorable trends in progression-free and overall survival, including a preliminary estimate of median overall survival of 10.3 months, are very encouraging," commented Professor Roger B. Cohen, Principal Investigator of the study. "We also saw evidence of clinical activity in both IO-naive and IO-pretreated patients. If confirmed, these data would provide support for a highly novel immunotherapeutic combination with a unique mechanism of action for the treatment of patients with head & neck cancer."

Data from the cohort of 40 patients were reported at 2018 ESMO (Free ESMO Whitepaper) congress in October. Exploratory subgroup analysis revealed encouraging responses, durability of response, PFS and OS in IO-naïve and IO-pretreated patients.

Eric Vivier, Chief Scientific Officer of Innate Pharma, said: "We are combining the use of state-of-the-art technologies including high-dimensional flow cytometry, single cell RNA seq and computational pathology, to monitor the immune response in patients. Data support the mode of action of monalizumab as unleashing a multilayered immune response involving both NK and T cells. As such, monalizumab appears as a first-in-class second generation immune checkpoint inhibitor with a large spectrum of immune targets. He added: "While preliminary, translational results suggest that the combination of monalizumab and cetuximab is associated with a reshaping of "cold tumors" into "hot tumors" prone to sustain tumor immunity".

Preliminary biomarker analysis show indeed that while the combination did not impair the distribution or absolute counts of peripheral NKG2A+ NK and CD8+ T cells, an infiltration of NK cells and CD8+T cells is detected very early upon treatment (day 15) at the tumor bed. Further, tumor-infiltrating NK and CD8+ T cells may be predictive of RECIST response, tumor reduction and PFS.

Importantly, the activity of the monalizumab and cetuximab combination appears to occur across HPV status, tumor burden and PD-L1 expression.

"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.
