NewLink Genetics Presents Preclinical Data on NLG919, a New Drug Candidate from a Novel Class of IDO Pathway Inhibitors for the Treatment of Cancer

AMES, Iowa, April 4, 2013 /PRNewswire/ -- NewLink Genetics Corporation (NASDAQ: NLNK) is a biopharmaceutical company focused on discovering, developing and commercializing cancer therapeutics. The company today announced that preclinical data on one of its IDO pathway inhibitors, NLG919, will be presented at the 2013 Annual Meeting of the American Association for Cancer Research (AACR) to be held April 6-10 in Washington, DC. The poster presentation will describe the benefits of targeting the IDO pathway with small molecule immunomodulatory drugs for the treatment of cancer. NLG919 is in development as a potent IDO pathway inhibitor with desirable pharmacological properties.

Poster presentation:

• (Poster #491): Sunday, April 7, 2013, 1:00 -5:00 PM, "NLG919, a novel indoleamine-2,3-dioxygenase (IDO)-pathway inhibitor drug candidate for cancer therapy," M. Mautino^, Immunology 2: Vaccines, Immune Modulatory Agents, and Environment, Hall A-C, Poster Section 22, in The Washington Convention Center.

About inhibition of the IDO pathway

IDO pathway inhibitors are another class of immune check point inhibitors akin to the recently developed antibodies targeting CTLA-4 and PD-1 which represent a potential breakthrough approach to cancer therapy.  The IDO pathway regulates immune response by suppressing T-cell function and enabling local tumor immune escape. Recent studies have demonstrated that the IDO pathway is active in many cancers, both within tumor cells as a direct defense against T-cell attack, and also within antigen presenting cells in tumor draining lymph nodes whereby this pathway promotes peripheral tolerance to tumor associated antigens (TAAs).  When hijacked by developing cancers in this manner, the IDO pathway may facilitate the survival, growth, invasion and metastasis of malignant cells expressing TAAs that might otherwise be recognized and attacked by the immune system.  NewLink has a number of active programs directed at synthesizing IDO pathway inhibitors.  These small-molecule, anti-tolerogenic product candidates are intended to counteract this key mechanism by which tumors evade immune-mediated destruction.

About NewLink Genetics Corporation

NewLink Genetics Corporation is a biopharmaceutical company focused on discovering, developing and commercializing novel immunotherapeutic products to improve treatment options for cancer patients. NewLink's portfolio includes biologic and small molecule immunotherapy product candidates intended to treat a wide range of oncology indications. NewLink's product candidates are designed to harness multiple components of the immune system to combat cancer without significant incremental toxicity, either as a monotherapy or in combination with other treatment regimens. NewLink's lead product candidate, algenpantucel-L (HyperAcute® Pancreas) is being studied in a Phase 3 clinical trial in surgically resected pancreatic cancer patients (under a Special Protocol Assessment with the U.S. FDA) as well as in a separate study in locally advanced pancreatic cancer patients. NewLink has recently launched an adaptive design Phase 2B/3 clinical trial of tergenpumatucel-L (HyperAcute® Lung) in patients with non-small cell lung cancer. NewLink is developing indoximod, a small molecule, orally bioavailable product candidate from NewLink's proprietary indoleamine-(2,3)-dioxygenase, or IDO, pathway inhibitor technology. NewLink is studying indoximod in various chemotherapy and immunotherapy combination studies independently and in collaboration with the National Cancer Institute.
