nuc-Gemcitabine consists of Antisoma’s AS1411*, a clinically-tested DNA aptamer against surface nucleolin found on many cancer cells, and dFdCMP, an activated form of gemcitabine. Unlike ADCs (antibody drug conjugates) or SMDCs (small molecule drug conjugates), which require ‘linker’ conjugation of the cytotoxic payload to the drug, nuc-gemcitabine is created by incorporating a single activated gemcitabine molecule in lieu of a thymidine molecule during the one-step solid phase synthesis of the DNA aptamer.

Clinical trials in over 80 cancer patients showed AS1411 to have modest anti-cancer activity and a favorable safety profile. nuc-Gemcitabine is 100-1,000x more potent compared to AS1411 or conventional gemcitabine (Gemzar) in pre-clinical studies. Composition of matter patent has been granted in major countries, including the United States.

"Nucleolin is constantly and abundantly expressed on the cell surface of tumor cells where it serves as a binding protein for a variety of ligands implicated in cancer growth and angiogenesis," said Dr. SungHwan Moon, President and Chief Scientific Officer of AptaBio. "High nucleolin expression is correlated with decreased survival. nuc-Gemcitabine binds to surface nucleolin with high specificity and affinity, leading to internalization of the aptamer-drug into tumor cells, where it mediates cell death. We have demonstrated significantly greater anti-cancer activity at low doses of nuc-gemcitabine containing the equivalent of 3 mg/kg gemcitabine versus 80-100 mg/kg of Gemzar in gemcitabine-resistant pancreatic cancer xenograft mouse models."

"HOPE-888 has demonstrated impressive anti-cancer activity in preclinical models. It could truly be a game changing treatment strategy for pancreatic cancer and other difficult-to-treat malignancies," said George Uy, CEO and Founder of HOPE. "Our goal is to file IND application in the next 12-18 months and bring it into the clinic soon thereafter. We intend to truly personalize nuc-gemcitabine therapy by screening patients for nucleolin-expression with a biomarker kit."

The Company also announces that it has accepted an invitation from The Cholangiocarcinoma Foundation (CCF) to present its initial research plans for use of PHP therapy in the treatment ICC. The CCF is the largest patient advocacy organization devoted to finding a cure and improving the quality of life for patients with cholangiocarcinoma, or bile duct cancers. Company representatives will present a summary of European investigator findings and its clinical development plans for ICC to the Foundation’s medical advisory board at the CCF’s 2017 Annual Meeting, to be held in Salt Lake City, UT from February 1-3, 2017. Delcath will also provide a sponsorship grant to support the work of the CCF as part of its participation in the CCF Annual Meeting.

"Though the interim data we expected for ICC cohort in our Phase 2 trial in HCC/ICC are not yet available, the objectives for this study have largely been satisfied by the independent retrospective analysis conducted by our European investigators" said Jennifer K. Simpson, Ph.D., MSN, CRNP, President and Chief Executive Officer of Delcath. "The promising outcomes and observations identified at our global KOL forum last year provide us with considerable confidence in the potential of our therapy in the ICC tumor type and helped form our initial research plan. The future research in ICC is designed to be cost effective and pursued in a financially prudent manner."

Dr. Simpson continued, "the CCF is one of the most important organizations for patients diagnosed with bile duct cancers, and the organization has attracted the participation of some of the leading researchers working on this difficult to treat disease. We are delighted with the opportunity to present to KOLs in this space the potential that the European investigators have identified for our therapy in the treatment of ICC."

About ICC
ICC is the second most common primary liver tumor and represents approximately 15% of new hepatocellular carcinoma (primary liver cancer or HCC) cases diagnosed annually. Surgical resection, the standard of care, is not possible for an estimated 80% to 90% of patients diagnosed with ICC.

The NDA filing includes data demonstrating the bioequivalence of CINVANTI to EMEND IV (fosaprepitant), supporting its efficacy for the prevention of both acute and delayed CINV with both moderately emetogenic chemotherapy (MEC) and highly emetogenic chemotherapy (HEC). Results also showed CINVANTI was better tolerated than EMEND IV, with significantly fewer adverse events reported with CINVANTI.

"The filing of the NDA for CINVANTI is an important milestone, bringing us one step closer to a new NK1 receptor antagonist treatment option for cancer patients suffering from the debilitating side effects of chemotherapy," said Kimberly J. Manhard, Executive Vice President, Drug Development at Heron Therapeutics. "We look forward to working closely with the FDA during the review of the NDA for CINVANTI in anticipation of FDA approval in late 2017."

"CINVANTI is based on the most widely used NK1 receptor antagonist, with almost 9 years of safety and efficacy experience," said Barry D. Quart, Pharm.D., Chief Executive Officer of Heron Therapeutics. "Since NK1 receptor antagonists are used in combination with 5-HT3 receptor antagonists, CINVANTI offers a strong strategic and operational fit with Heron’s existing commercial product, SUSTOL, our extended-release, injectable product that incorporates the 5-HT3 receptor antagonist granisetron and is also indicated for the prevention of CINV."

About CINVANTI (HTX-019) for CINV
CINVANTI is a proprietary intravenous formulation of aprepitant, a NK1 receptor antagonist for the prevention of CINV. NK1 receptor antagonists are typically used in combination with 5-HT3 receptor antagonists. Currently, the only injectable NK1 receptor antagonist approved in the U.S. contains polysorbate 80, a surfactant, which may cause hypersensitivity reactions, infusion site reactions or other adverse reactions in some patients. Heron’s formulation for CINVANTI does not contain polysorbate 80 and may have a lower incidence of certain types of adverse reactions than reported with the other commercially available injectable NK1 receptor antagonist.

About SUSTOL (granisetron) extended-release injection
SUSTOL is indicated in combination with other antiemetics in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of MEC or anthracycline and cyclophosphamide (AC) combination chemotherapy regimens. SUSTOL is an extended-release, injectable 5-HT3 receptor antagonist that utilizes Heron’s Biochronomer polymer-based drug delivery technology to maintain therapeutic levels of granisetron for ≥5 days. The SUSTOL global Phase 3 development program was comprised of two, large, guideline-based clinical trials that evaluated efficacy and safety in more than 2,000 patients with cancer. The efficacy of SUSTOL in preventing nausea and vomiting was evaluated in both the acute phase (day 1 following chemotherapy) and the delayed phase (days 2-5 following chemotherapy). Please see full prescribing information, including additional important safety information, available at www.SUSTOL.com.

Kitov Enters Immuno-Oncology Field Through Acquisition of TyrNovo

On January 12, 2017 Kitov Pharmaceuticals Holdings Ltd.

The expansion into developing immuno-oncology drugs comes as Kitov plans to file its New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) for its flagship combination drug, KIT-302, which is intended to treat osteoarthritis pain and hypertension simultaneously, in Q1 2017, with commercial launch anticipated for the first half of 2018. Kitov plans to harness its development and regulatory capabilities in proceeding towards submitting an investigational new drug (IND) application with the U.S. FDA and initiate clinical trials for its newly acquired drug, NT219.

The market for immuno-oncology treatments is believed to become worth $14 billion by 2019 and to grow to $34 billion by 2024, driven by long-term and durable tumor responses to immuno-oncology drugs, according to Global Data.

Kitov will initially acquire an approximately 56% equity stake in TyrNovo from its majority shareholder, for consideration of $2 million in cash and $1.8 million equivalent ordinary shares of Kitov based on the closing price of Kitov’s shares on the TASE on January 11, 2017. Following the closing of this initial acquisition, which is expected to take place on January 13, 2017, Kitov anticipates that it may acquire additional equity stakes in TyrNovo from all or part of TyrNovo’s additional minority shareholders for consideration consisting of ordinary shares of Kitov in such amounts as to be agreed with the shareholders.

"The TyrNovo acquisition represents a major milestone in Kitov’s strategic vision of establishing a diverse pipeline that we believe will secure long term value creation for its shareholders. We are excited about NT219 and its prospects in the oncology field. NT219 can be developed as a platform combination drug for overcoming multi-drug resistance often observed in various tumors. It has the potential to be developed as a combination therapy with several approved oncology drugs for multiple types of tumors," stated Dr. Paul Waymack, Kitov’s Chairman and Chief Medical Officer.

"The Kitov regulatory team has a proven track record in the development and approval of drugs for oncology as well as other indications required to develop NT219 towards submission of an IND and initiation of clinical trials," Waymack added.

TyrNovo is led by its CEO, Dr. Hadas Reuveni, a co-inventor of the TyrNovo technology, who received her Ph.D., Summa Cum Laude, for anti-cancer drug discovery from the Hebrew University of Jerusalem and has nearly two decades of R&D experience in Biotechnology. Dr. Reuveni commented, "I am excited to join Kitov and its team to expedite the development of NT219, which addresses a true unmet medical need for numerous oncology indications. Cancer drug resistance is the major reason for failure in anti-cancer drug treatment. Preventing resistance to the drugs is critical for improving effective cancer treatment."

About NT219

NT219 is a small molecule that presents a new concept in cancer therapy by promoting the degradation of two oncology-related checkpoints, Insulin Receptor Substrates (IRS) 1 and 2 as well as the inhibition of signal transducer and activator of transcription 3 (STAT3). While targeted anti-cancer drugs inhibit the "ON" signal, NT219 activates the "OFF" switch, extensively blocking major oncogenic pathways. In pre-clinical trials, NT219, in combination with several approved cancer drugs, displayed potent anti-tumor effects and increased survival in various cancers by preventing the tumors from developing multi-drug resistance and ameliorating multi-drug resistance after resistance is acquired. NT219, in combination with various approved oncology drugs, demonstrated potent anti-tumor effects and increased survival in various cancer models including sarcoma, melanoma, pancreatic, lung, ovarian, head & neck, prostate and colon cancers, through the prevention of acquired resistance and regression of resistant tumors.
