Dr. Bourgeaux stated, "Methionine dependence has emerged as a unique target for anti-cancer activity during the last two decades. While methionine gamma-lyase is a promising strategy for these cancers, its very short half-life in the body prohibited all attempts to develop MGL as cancer therapy. However, our work here shows that when encapsulated in red blood cells using our ERYCAPS technology, MGL is protected from degradation and overcomes the pharmacokinetic limitations resulting in increased half-life in vivo for effective potential use in a broad-range of methionine-dependent cancers."
Gil Beyen, Chairman and CEO of ERYTECH, added, "Erymethionase represents a novel product candidate in our tumor starvation arsenal. ERYTECH is progressively building its cancer metabolism platform with this second product candidate to complement eryaspase (GRASPA), ERYTECH’s lead product candidate. The posters presented at two immunotherapy medical meetings earlier this month and now promising data with erymethionase at AACR (Free AACR Whitepaper) underscore ERYTECH’s intention to develop the scope of products and applications for its technology platform."
Methionine is an essential amino acid, which is necessary for all cells to grow and multiply. More specifically, fast-growing tumor cells exhibit very high requirements of methionine to proliferate. The enzyme methionine gamma-lyase (MGL) mediates tumor starvation via systemic lowering of methionine levels. MGL is an enzyme with a short half-life and is dependent on a co-factor, a Vitamin B6 derivative which is naturally present in red blood cells, to demonstrate enzymatic activity. The preclinical studies in mouse models of erymethionase aimed to investigate the protection of MGL against degradation and immune reactions through encapsulation in erythrocytes (red blood cells).
ERYTECH researchers demonstrated that encapsulation of MGL in red blood cells both strongly improved the half-life of the enzyme and provided active co-factor to increase MGL activity and therefore, tumor starvation. The half-life of MGL increased from less than 24 hours when free to more than 10 days when encapsulated in red blood cells, with no toxicity reported. The preclinical study showed that combining a single weekly intravenous injection of erymethionase with daily pyridoxine (PN) supplementation led to a sustained methionine depletion in the plasma, and an inhibition of tumor growth for 45 days following the fifth erymethionase dose of 85% in the glioblastoma mouse model, and of 72% in the gastric cancer mouse model. Repeated injections of ERY-MET were also effective against established tumors in the gastric cancer model leading to a complete tumor regression.

Blueprint Medicines Announces Enrollment of First Patient in Phase 1 Clinical Trial for BLU-667
On March 20, 2017 Blueprint Medicines Corporation (NASDAQ: BPMC), a leader in discovering and developing targeted kinase medicines for patients with genomically defined diseases, reported that it has dosed the first patient in a Phase 1 clinical trial of BLU-667, an investigational RET inhibitor for patients with non-small cell lung cancer (NSCLC), medullary thyroid cancer (MTC) and other advanced solid tumors that harbor a RET alteration (Press release, Blueprint Medicines, MAR 20, 2017, View Source [SID1234518223]). Schedule your 30 min Free 1stOncology Demo! "By rapidly initiating a clinical trial for our potent and selective RET inhibitor BLU-667, we have successfully achieved a key 2017 milestone," said Jeff Albers, Chief Executive Officer of Blueprint Medicines. "This continued progress underscores our commitment to build Blueprint Medicines into a sustainable company. BLU-667 has a unique product profile differentiated from our other clinical-stage programs by its potential to address predicted resistance mutations that may arise. With BLU-667 enrollment underway, we are further increasing our diversified pipeline of potent, highly selective investigational medicines that target specific disease drivers in genomically-defined patient populations."

"RET fusions and mutations are recognized as important drivers in multiple cancers, but existing multi-kinase inhibitors with RET activity do not provide sufficient, durable benefit for patients with RET alterations," said Andy Boral, M.D., Ph.D., Chief Medical Officer of Blueprint Medicines. "BLU-667 is being developed to potently inhibit RET, and simultaneously prevent the development of on-target resistance, which we believe will provide more lasting clinical benefit and prevent or delay disease recurrence. We look forward to working with patients and physicians to explore BLU-667’s potential."
BLU-667 is an orally available, potent and selective inhibitor designed to target RET mutations, fusions and predicted resistance mutants. RET activating fusions and mutations are a key disease driver in multiple cancers, including NSCLC and MTC, with RET fusions implicated in approximately 1-2% of patients with NSCLC, and RET mutations implicated in approximately 60% of patients with MTC. In addition, genomic analyses published by scientists at Blueprint Medicines have identified RET fusions at low frequencies in colon and breast cancer. Currently, there are no approved therapies that selectively target RET-driven cancers, though there are several approved multi-kinase inhibitors with RET activity being evaluated in clinical trials. Thus far, clinical activity attributable to RET inhibition has been uncertain for these inhibitors, likely due to insufficient inhibition of RET and off-target toxicities. In preclinical studies using biochemical and cellular assays, and tumor models, BLU-667 was active against RET fusions and mutations, including predicted resistance mutations.
About the Phase 1 Clinical Trial for BLU-667 in RET
Blueprint Medicines’ Phase 1 clinical trial of BLU-667 in RET is designed to evaluate the safety and tolerability of BLU-667 in multiple ascending doses in patients with NSCLC, MTC, and other advanced solid tumors with the goal of establishing a maximum tolerated dose (MTD) or a lower recommended dose if appropriate. Once the MTD is reached, or a recommended dose is established, Blueprint Medicines plans to open expansion cohorts for NSCLC patients with a RET rearrangement, patients with MTC, and patients with RET-altered solid tumors other than NSCLC and MTC. Secondary objectives for this Phase 1 clinical trial include assessing the pharmacokinetic profile of BLU-667, assessing RET gene status in plasma and tumor tissue, characterizing the pharmacodynamic effects of BLU-667 and assessing response rate by Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1, which are criteria commonly used to measure clinical responses in solid tumors. The Phase 1 clinical trial is designed to enroll approximately 115 patients, including approximately 35 patients during dose escalation and approximately 80 additional patients in expansion cohorts, at multiple sites in the United States and the European Union. Please refer to www.clinicaltrials.gov (NCT03037385) for additional details related to this Phase 1 clinical trial.

The parties plan to first globally commercialize an analytical assay and then develop a Class III assay for pre-market approval (PMA) from the U.S. Food and Drug Administration (FDA). FDA approval will be based on analyses of patient samples collected from ongoing larotrectinib clinical trials to support clinical claims referencing larotrectinib. Roche is responsible for developing, obtaining and maintaining regulatory approvals for the companion diagnostic test in the United States, specified countries in the European Union and other countries that recognize the CE/ in vitro diagnostic registration process, as mutually agreed.
About Larotrectinib (LOXO-101)
Larotrectinib (LOXO-101) is a potent, oral and selective investigational new drug in clinical development for the treatment of patients with cancers that harbor abnormalities involving the tropomyosin receptor kinases (TRKs). Growing research suggests that the NTRK genes, which encode for TRKs, can become abnormally fused to other genes, resulting in growth signals that can lead to cancer in many sites of the body. In an ongoing Phase 1 clinical trial, larotrectinib has demonstrated encouraging preliminary efficacy. Larotrectinib is also being evaluated in the NAVIGATE global Phase 2 multi-center basket trial in patients with solid tumors that harbor TRK gene fusions, and the SCOUT Phase 1/2 trial in pediatric patients, including patients with advanced cancer, TRK gene fusions and infantile fibrosarcoma. Larotrectinib has been granted Breakthrough Therapy Designation and Rare Pediatric Disease Designation by the U.S. FDA. For additional information about the larotrectinib clinical trials, please refer to www.clinicaltrials.gov. Interested patients and physicians can contact the Loxo Oncology Physician and Patient Clinical Trial Hotline at 1-855-NTRK-123 or visit www.loxooncologytrials.com.
Major Achievements in 2016 Validate Transgene’s Strategy and Provide Promising Outlook for 2017
On March 20, 2017 Transgene (Paris:TNG) (Euronext Paris: TNG), a biotechnology company focused on designing and developing viral-based immune-targeted therapies for the treatment of cancers and infectious diseases, reported its financial results for the fiscal year ended December 31, 2016, and provided its outlook for 2017 (Press release, Transgene, MAR 20, 2017, View Source [SID1234518217]).

In 2016, Transgene has focused its efforts on implementing its strategy, which looks to combine Transgene’s immunotherapies (therapeutic vaccines and oncolytic viruses, which boost the immune system), with immune checkpoint inhibitors (ICIs). Over the last twelve months, additional data from clinical studies combining active immunotherapies with ICIs have confirmed the strong rationale behind this strategy.
During the second half of 2016, Transgene signed two clinical collaboration agreements that allow clinical studies with:
TG4010 in combination with Bristol Myers-Squibb’s ICI nivolumab in lung cancer patients receiving a 2nd line of treatment and;
TG4001 with Merck KGaA’s and Pfizer’s ICI avelumab in patients with HPV-positive head and neck cancer.
Several clinical trials have recently started or are being initiated to confirm the potential of Transgene’s immunotherapeutics in combination with ICIs. The first results from these studies are expected around the end of 2017.
During the 2016 fiscal year, the Company strengthened its financial structure which will provide it with the funding to execute its clinical development plan through the end of 2018. This improved financial situation was the result of:
a loan of €20 million from the European Investment Bank (EIB), €10 million of which was drawn down in June 2016 ;
a €46.4 million rights issue that was completed in November 2016;
as well as the significant reduction of our net loss €25.2 million compared to €46.4 million in 2015.
In parallel with strengthening its financial position, Transgene completed its reorganization with the result it is now focused on research and clinical development (R&D). As part of the restructuring, Transgene sold its production facility to ABL Europe, a Mérieux Group Company, for €3.5 million.
Philippe Archinard, Chairman and Chief Executive Officer of Transgene said: "Our achievements in 2016 have reinforced our position as a major player in immunotherapy. Our portfolio of immunotherapies, our clinical collaborations and our much-improved financial position have put us in a strong position to execute our clinical plan which is designed to deliver a rich news flow over the coming months. Positive results from these studies would allow us to conclude partnership agreements with pharmaceutical companies. We are looking forward to demonstrating the important clinical benefits that our immunotherapies in combination with ICIs can offer to patients with severe diseases."

These novel therapeutic payloads are designed to modify cell interactions within the tumor and enhance the efficacy of oncolytic viruses.
Transgene has filed a patent for an oncolytic Vaccinia Virus expressing an anti-PD1 antibody. Transgene presented a poster at the AACR (Free AACR Whitepaper) (American Association for Cancer Research) meeting in April 2016, demonstrating our capacity to engineer advanced multifunctional viruses.
Corporate
Restructuring plan and sale of the production facility to ABL Europe for €3.5 million finalized. Annualized recurring savings are estimated to be approximately €15 million.
Management team strengthened: Maud Brandely, MD, PhD appointed Chief Medical Officer, and John Felitti, JD, LLM appointed General Counsel & Corporate Secretary.
Key financials for 2016
Net cash burn for 2016 was €30.6 million (including €5 million linked to the restructuring), versus €34.8 million in 2015. This was lower than expected due to a delay in an $4 million milestone payment to SillaJen. This payment is to be made in early 2017.
Cash available at year-end 2016: €56.2 million, compared to €31.7 million at the end of 2015. This higher cash balance includes the €10 million draw-down of the EIB loan and the net proceeds of €45.2 million from the rights issue which was concluded in November 2016.
Net operating expenses of €33.0 million in 2016, compared to €45.8 million in 2015.
Significantly reduced net loss of €25.2 million in 2016, compared to a loss of €46.4 million in 2015.
"Transgene’s 2016 financials reflect the completion of the reorganization that started in 2015. This has led to a significant reduction of our operating costs and as a result a 46% reduction in our net loss when compared to 2015. This reduction in fixed costs has enabled us to devote a greater proportion of our increased financial resources to our key strategic clinical and pre-clinical programs," said Jean-Philippe Del, Vice President, Finance.
The financial statements for 2016 as well as management’s discussion and analysis are attached to this press release (Appendices A and B).
Financial Outlook 2017
Transgene expects its cash burn to be around €30 million in 2017. This figure takes into account the increase in costs related to the launch of clinical trials in 2017, as well as a confirmed significant reduction of our fixed costs following the restructuring that has taken place since 2015.
The Company still has access to further funding of up to €10 million from the second tranche of the EIB loan.
Transgene will host a "R&D Day", on June 22, 2017. The event which will be conducted in English will feature presentations from several leading international scientists and clinicians.
The Board of Directors of Transgene met on March 17, 2017, under the chairmanship of Philippe Archinard and closed the 2016 financial statements. Audit procedures have been performed by the statutory auditors and the delivery of the auditors’ report is ongoing. The registration document, which includes the financial report, will be available in April 2017 on Transgene’s website, www.transgene.com.
A conference call in English is scheduled on March 20th at 6 PM CET.
