It is a spin-out from the University of Helsinki, Valo Therapeutics is developing novel oncolytic viral vaccines for the treatment of multiple forms of cancer. The therapeutic platform is projected to target cancer by recruiting the body’s own defence mechanisms to clear the cancer and subsequently to give patients a lasting resistance to recurring disease (vaccination). Valo Therapeutics recently closed its seed funding round, establishing strategic partnerships with world class investors in this rapidly growing scientific space.

The funding will take the company through pre-clinical development of a proprietary and genetically modified adenovirus coupled with tumor-specific peptides, that can both directly target cancer cells as well as elicit a strong and lasting specific anti-tumor immune response. A highly experienced team with deep experience of oncolytic viruses and clinical trials is driving development.

Current oncolytic viral therapies mostly focus on direct tumor cell lysis and typically generate a strong anti-viral immune response plus a weaker anti-tumor effect. Valo Therapeutics has disguised its viral particles using tumor-specific antigens (peptides), which can provide the information necessary to direct the immune response toward the patient’s tumor. This patented technology was developed by Scientific Founder Professor Vincenzo Cerullo, Head of the Drug Research Program at the University of Helsinki in the Faculty of Pharmacy, and a leader in his field: “Our approach seeks to revolutionise the way oncolytic virotherapies will be used in the future” said Prof. Cerullo, adding, “this technology is applicable to nearly all viruses being used at the moment”.

Dr. Michael Stein is the incoming Chairman of Valo Tx (currently Chairman and CEO of OxStem, the award winning spin-out from the University of Oxford). Dr Stein observed: “I was struck by the quality of the company’s very promising pre-clinical data. In addition, the team is equipped with all the expertise necessary to accelerate this treatment to market, providing patients with a potentially transformational therapy”. Dr. Stein continued, “Valo Tx is fortunate to have the strategic backing of some highly experienced investors including the University of Helsinki, as well as the resources of the University of Helsinki Innovation Services” (HIS).

HIS supported the company in preparing the initial spin-out and will continue to provide support for full commercialisation of the technology. Jari Strandman, CEO of Helsinki Innovation Services: “We are incredibly excited about the potential of this new technology and delighted to see the rapid progress already being made”.

Freeman Road is a family consortium with deep experience in the healthcare technology space, and a primary Investor in Valo Therapeutics. Director and Physician Dr. Paul Porter said: “We invested into Valo Tx because the business concept is novel, with potential for enormous impact; and it is backed by a highly experienced team”.

Valo Therapeutics will fund the progression of its new therapy through clinical trials in humans in 2018 – each with a focus on a different cancer indication with large unmet therapeutic need. The team will focus initially on two cancer indications as a proof of concept, with a view to expanding to other cancer types over time.

On January 30, 2017 Aeterna Zentaris Inc. (NASDAQ: AEZS) (TSX: AEZ) (the "Company") reported the occurrence of the 384th death in the pivotal Phase 3 ZoptEC (Zoptarelin Doxorubicin in Endometrial Cancer) study with Zoptrex (zoptarelin doxorubicin) in women with advanced, recurrent or metastatic endometrial cancer, representing the clinical endpoint of the study (Press release, AEterna Zentaris, JAN 30, 2017, View Source [SID1234517598]). The Company currently expects to lock the clinical database and to report top-line results in April 2017. Zoptrex is the Company’s proposed tradename for zoptarelin doxorubicin. The proposed tradename is subject to approval by the United States Food and Drug Administration (the "FDA").

Dr. Richard Sachse, the Company’s Chief Scientific Officer, stated, "We are pleased to announce the completion of the clinical phase of our pivotal Phase 3 clinical study of Zoptrex, which was conducted under a Special Protocol Assessment with the FDA. Reaching this important milestone took longer than we anticipated because the rate of events slowed significantly during the past year. As previously reported, the study was fully enrolled in June 2015 and the final dosing occurred in January 2016. Therefore, a significant number of patients survived more than 18 months since enrollment in the study. We are thankful that these patients continued to survive a devastating disease and are hopeful that their lives are continuing successfully. We are close to locking the clinical database and are focused on producing the top-line results of the study. Currently, we expect to release top-line results in April 2017."

David A. Dodd, President and Chief Executive Officer of the Company stated, "With the completion of the clinical portion of this trial, we will now focus on analyzing the data and, if warranted by the results, submitting a new drug application later this year. There is a significant unmet medical need for a treatment for women with advanced, recurrent or metastatic endometrial cancer and we are hopeful that Zoptrex will provide clinicians and their patients with an effective therapy for treating the disease. We are indebted to all 512 patients who participated in this important clinical program and, hopefully, we will advance to providing a very important new therapy for this devastating cancer."

About the ZoptEC Pivotal Phase 3 Trial

The ZoptEC pivotal Phase 3 trial was a fully-recruited (over 500 patients), open-label, randomized-controlled study, comparing the efficacy and safety of zoptarelin doxorubicin, a hybrid molecule composed of a synthetic peptide carrier and a well-known chemotherapy agent, doxorubicin, to doxorubicin alone. Patients were centrally randomized in a 1:1 ratio and received either Zoptrex (267 mg/m2) or doxorubicin (60 mg/m2) intravenously, every three weeks and for up to nine cycles. Response was evaluated every three cycles during treatment, and thereafter, every 12 weeks until progression. All patients were followed for survival as the primary efficacy endpoint ("EP"). Secondary EPs include progression-free survival, objective response-rate, and clinical benefit rate. The trial is being conducted under a Special Protocol Assessment with the U.S. Food and Drug Administration ("FDA"). For more information on this trial, please consult (ClinicalTrials.gov Identifier: NCT01767155; EudraCT No: 2012-005546-38; ZoptEC: Zoptarelin doxorubicin in endometrial cancer).

About Zoptarelin Doxorubicin

Zoptrex (zoptarelin doxorubicin), a novel synthetic peptide carrier linked to doxorubicin as a New Chemical Entity (NCE), is the Company’s lead oncology compound. Zoptrex is the first targeted oncological therapy using a peptide as the targeting agent and, therefore, it represents potentially a new tool in the treatment of cancer tumors that overexpress the LHRH receptor. The design of the compound allows for the specific binding and selective uptake of the cytotoxic conjugate by LHRH receptor-positive tumors, typically found in gynecological cancers, prostate cancer and some forms of breast cancer. Potential benefits of this targeted approach may include enhanced efficacy and a more favorable safety profile with lower incidence and severity of adverse events, as compared to doxorubicin. Based on the results of Phase 2 studies, the Company believes it may be efficacious for the treatment of ovarian and prostate cancer. If Zoptrex is approved as a therapy for endometrial cancer, the Company intends to develop it for these additional indications. The Company has licensed marketing rights to Zoptrex to Sinopharm A-Think for China, Hong Kong and Macau; to Orient EuroPharma for Taiwan and Southeast Asia; to Rafa Labs for Israel and the Palestinian territories and to Specialised Therapeutics for Australia and New Zealand.

About Endometrial Cancer

Endometrial cancer is the most common gynecologic malignancy in developed countries and develops when abnormal cells amass to form a tumor in the lining of the uterus. It largely affects women over the age of 50 with a higher prevalence in Caucasians and a higher mortality rate among African Americans. According to the American Cancer Society, there will be approximately 50,000 new cases of endometrial cancer in the U.S. alone in 2015, with about 20% of recurring disease.

On January 30, 2017 Exelixis, Inc. (NASDAQ:EXEL) and Takeda Pharmaceutical Company Limited (TSE:4502) reported an exclusive licensing agreement for the commercialization and further clinical development in Japan of cabozantinib, Exelixis’ lead oncology medicine (Press release, Exelixis, JAN 30, 2017, View Source [SID1234517596]). With the signing of the agreement, Takeda gains exclusive commercial rights for all potential future cabozantinib indications in Japan, including advanced renal cell carcinoma (RCC), for which cabozantinib is marketed in the United States and European Union as CABOMETYX tablets. The two companies will collaborate on the future clinical development of cabozantinib in Japan.

Under the terms of the agreement, Exelixis will receive a $50 million upfront payment. Exelixis is eligible to receive development, regulatory, and first-sales milestones of $95 million for the first three planned indications. In addition,
Exelixis will be eligible to receive royalties on sales by Takeda.

"As an organization with a strong focus on oncology innovation, our agreement with Exelixis brings a promising and well-studied solid-tumor therapy to our pipeline that may help patients in Japan suffering from RCC and potentially other equally devastating cancers," said Tsudoi Miyoshi, Head of Japan Oncology Business Unit of Takeda. "We intend to pursue regulatory approval for RCC indications as soon as we’re able, and look forward to commencing the local clinical trial program to further strengthen the clinical profile of cabozantinib."

Exelixis and Takeda will partner on cabozantinib’s clinical development in Japan and on translating existing and forthcoming clinical data for potential regulatory filings in the country. In the METEOR pivotal trial, cabozantinib demonstrated statistically significant improvements in overall survival, progression-free survival and objective response rate, meaningfully differentiating it from other therapies to treat advanced renal cell carcinoma following prior therapy. In addition to advanced RCC, future indications could include advanced hepatocellular cancer (HCC), the subject of the CELESTIAL global pivotal trial for which results are anticipated in 2017. Additional earlier-stage studies are under way through Exelixis’ collaboration with the National Cancer Institute’s Cancer Therapy Evaluation Program, and its ongoing Investigator-Sponsored Trial program. Through these two programs, there are more than 45 ongoing or planned studies including trials in advanced RCC, bladder cancer, colorectal cancer, non-small cell lung cancer, and endometrial cancer.

"Takeda is the ideal partner to advance cabozantinib in Japan and deliver this important treatment option to Japanese patients with cancer," said Michael M. Morrissey, Ph.D., President and Chief Executive Officer of Exelixis. "Takeda is widely respected for both its clinical development and commercial expertise. We look forward to supporting our new partner as it pursues Japanese regulatory approval for cabozantinib, while simultaneously working together to plan the next steps for clinical development in the country. This agreement further propels the global progress for cabozantinib development and commercialization, which now includes the recent first commercial sale of
CABOMETYX in the United Kingdom, triggering a $10 million milestone payment from Ipsen to Exelixis."

Cabozantinib is not approved for use in Japan. Previously, Exelixis and its collaborators conducted early-stage clinical trials in Japan, including a phase 1 trial in advanced solid tumors. Data from this trial were presented at the European Society for Medical Oncology 2012 Congress and the 2015 AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper).1,2

Exelixis maintains its exclusive rights to develop and commercialize cabozantinib in the United States, and its partner Ipsen maintains its exclusive commercialization rights for current and potential future cabozantinib indications outside of the United States and Japan.
