"We hope that the addition of ADI‑PEG 20, which has a different mechanism of action than cytarabine, will result in both safety and added efficacy", said John Bomalaski, M.D., Executive Vice President, Medical Affairs at Polaris Pharmaceuticals, Inc.

About ADI‑PEG 20

ADI‑PEG 20 is a biologic being developed by Polaris Group to treat cancers carrying a major metabolic defect that renders them unable to internally synthesize arginine. Because arginine is essential for protein synthesis and survival of cells, these cancer cells become dependent upon the external supply of arginine to survive and grow. ADI‑PEG 20 is designed to deplete the external supply of arginine, causing arginine-dependent cancer cells to die while leaving the patient’s normal cells unharmed. Multiple cancers have been reported to have a high degree of arginine-dependency and can potentially be treated with ADI‑PEG 20.

Argos Therapeutics Completes Lease Agreement for Commercial Manufacturing Space on the Centennial Campus of North Carolina State University

On January 19, 2017 Argos Therapeutics Inc. (Nasdaq:ARGS) ("Argos"), an immuno-oncology company focused on the development and commercialization of individualized immunotherapies based on the Arcelis precision immunotherapy technology platform, reported the completion of a lease agreement with Keystone-Centennial II, LLC, for 40,000 square feet of newly constructed manufacturing space at the Center for Technology & Innovation (CTI) on the Centennial Campus of North Carolina State University in Raleigh, NC (Press release, Argos Therapeutics, JAN 19, 2017, View Source [SID1234517462]).

Argos plans to use the manufacturing space at CTI to prepare for submission of a biologics license application (BLA) to the U.S. Food & Drug Administration and to support initial commercialization of rocapuldencel-T, the company’s most advanced product candidate, which is being evaluated for the treatment of metastatic renal cell carcinoma (mRCC) in the company’s pivotal ADAPT Phase 3 clinical trial. Because the company’s Arcelis technology platform enables broad geographic coverage from a single facility, CTI is expected to support both domestic and international launches for the first few years, pending regulatory approval of rocapuldencel-T.

"Securing a lease for the CTI facility is a critical step on our path towards becoming a fully-integrated commercial-stage biotechnology company," said Jeff Abbey, president and chief executive officer of Argos. "Our two-stage manufacturing strategy positions us to employ an established and proven-effective manual manufacturing process at CTI with the capacity to support approximately 1,800 patients per year at launch, with expansion capacity to 2,400 patients per year, pending regulatory approval. This strategy optimizes capital utilization as we prepare for a BLA submission for rocapuldencel-T and also allows us to assess early commercial uptake and better project capacity requirements for our planned 125,000 square foot Centerpoint facility in Durham, NC, which can be designed to accommodate our automated manufacturing process."

"In our role of facilitating economic development, we applaud the commitment Argos is making to extend its research partnerships and North Carolina roots to Centennial Campus," said Dr. Alan Rebar, Vice Chancellor of Research, Innovation and Economic Development, at North Carolina State University. "We are excited that Argos has chosen CTI as it seeks to develop and commercialize cutting-edge immunotherapies for people with serious illnesses and look forward to a productive partnership."

About the Arcelis Technology Platform
Arcelis is a precision immunotherapy technology that captures both mutated and variant antigens that are specific to each patient’s individual disease. It is designed to overcome immunosuppression by producing a specifically targeted, durable memory T-cell response without adjuvants that may be associated with toxicity. The technology is potentially applicable to the treatment of a wide range of different cancers and infectious diseases, and is designed to overcome many of the manufacturing and commercialization challenges that have impeded other personalized immunotherapies. The Arcelis process uses only a small disease sample or biopsy as the source of disease-specific antigens, and the patient’s own dendritic cells, which are optimized from cells collected by a single leukapheresis procedure. The proprietary process uses RNA isolated from the patient’s disease sample to program dendritic cells to target disease-specific antigens. These activated, antigen-loaded dendritic cells are then formulated with the patient’s plasma, and administered via intradermal injection as an individualized immunotherapy.

Celsion to Present Two Posters on its GEN-1 IL-12 Gene-Mediated Immunotherapy at the ASCO-SITC Clinical Immuno-Oncology Symposium

On January 19, 2017 Celsion Corporation reported that it will present two posters at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) – Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Clinical Immuno-Oncology Symposium being held from February 23 – 25, 2017 in Orlando, FL (Press release, Celsion, JAN 19, 2017, View Source [SID1234517449]). The symposium will focus on the latest clinical and translational research in immuno-oncology and the implications for clinical care. The first poster will report clinical results from the Phase Ib dose escalating clinical trial (the OVATION Study) combining GEN-1, the Company’s IL-12 gene-mediated immunotherapy, with the standard of care for the treatment of newly-diagnosed patients with Stage III and IV ovarian cancer who will undergo neoadjuvant chemotherapy followed by interval debulking surgery. The second poster will report translational data from the OVATION Study and previous GEN-1 clinical trials. The posters will be presented by Khursheed Anwer, Ph.D., Celsion’s executive vice president and chief science officer.

Poster Presentation details:

Title: Phase I study and activity of formulated IL-12 plasmid administered intraperitoneally in combination with standard neoadjuvant chemotherapy in patients with newly diagnosed advanced stage ovarian cancer
Date and Time: Poster Session A – February 23, 2017 (11:30 am – 1:00 pm ET; 5:30 pm to 6:30 pm ET)
Poster Number: 155

Title: Immunological changes following intraperitoneal administration of a formulated IL-12 plasmid in combination with standard neoadjuvant chemotherapy in patients with newly diagnosed advanced stage ovarian cancer
Date and Time: Poster Session A – February 23, 2017 (11:30 am – 1:00 pm ET; 5:30 pm to 6:30 pm ET)
Poster Number: 156

"Our hypothesis is that GEN-1 plus neoadjuvant chemotherapy treatment will reprogram the tumor immune microenvironment towards a potent antitumor immune response," said Dr. Anwer. "The available data demonstrate highly relevant immunological changes in the tumor immune environment, such as tumor infiltration of cytotoxic T-cell lymphocytes and a reduction of certain immunosuppressive signals, which supports the immune activating role of GEN-1 in this patient population. Evidence of immune activation following the treatment is also supported by increases in IFN-g, a potent mediator of the anti-tumor immune response associated with IL-12 action. We are excited to present at the ASCO (Free ASCO Whitepaper)-SITC symposium, and look forward to sharing the impressive clinical and translational results with the scientific community."

The OVATION Study is designed to enroll three to six patients per dose cohort with the goal of identifying a safe, tolerable and immunologically active dose of GEN-1 by recruiting and maximizing an immune response. Enrollment in the fourth cohort is ongoing with the goal of enrolling three additional patients in this final dose cohort. Celsion expects to complete enrollment in the OVATION Study this quarter and report final data, including translational data for all patients, in the second quarter of 2017. Future studies of GEN-1 will include a Phase I/II study combining GEN-1 with Avastin and Doxil.
