AMES, IA--(Marketwired - Jun 2, 2014) - NewLink Genetics Corporation (NASDAQ: NLNK), a biopharmaceutical company focused on discovering, developing, and commercializing novel immunotherapeutics to improve treatment options for patients with cancer, demonstrated continuing progress with its IDO (indoleamine-(2,3)-dioxygenase) pathway inhibitor program at the American Society for Clinical Oncology (ASCO) 2014 annual meeting. In a series of presentations, NewLink researchers and collaborators presented multiple on-going clinical studies with its IDO pathway inhibitor candidates, expanding the immuno-oncology regimens being evaluated to include combinations with other immunotherapies, cancer vaccines, and chemotherapy. These presentations were highlighted by ASCO as trials in progress posters, demonstrating continued interest for innovative ongoing studies in IDO- mediated checkpoint inhibition.
Combination clinical studies presented that highlight NewLink's IDO pathway inhibitor product candidates include:
- Phase 1/2 study of NewLink's most advanced IDO pathway inhibitor, indoximod, in combination with ipilimumab (Yervoy) for unresectable stage 3 or 4 melanoma,
- Phase 1/2 study of indoximod in combination with temozlomide (Temodar) for primary malignant brain tumors,
- Phase 2 study of indoximod in combination with docetaxel (Taxotere) in metastatic breast cancer,
- Phase 2 study of indoximod after sipuleucel-T (Provenge) in metastatic castration-resistant prostate cancer,
- Phase 1 study of NLG919, the second product candidate from NewLink's IDO pathway inhibitor technology platform, for solid tumors.
"We believe NewLink is well positioned to continue to lead in the immune-oncology field as we now have 2 IDO pathway inhibitors from our rich IDO/TDO product pipeline in the clinic and our HyperAcute® platform products are continuing to make progress in the clinic across multiple indications," commented Dr. Nick Vahanian, President and Chief Medical Officer.
"With the initiation of these clinical studies we have significantly expanded the immuno-oncology combinations being evaluated with our IDO pathway inhibitor program, representing one of the broadest efforts in the biotech space. We plan to continue our efforts for even further expansion of our IDO program to additional indications by pursuing combination studies with chemotherapies and vaccines or other immune/check point modulators" commented Dr. Charles Link, Chairman and Chief Executive Officer of NewLink. "IDO pathway inhibition has previously demonstrated promising synergies and a good safety profile in preclinical studies in combination with other immunotherapies, cancer vaccines, and chemotherapy and we look forward to reporting on the anti-cancer activity of these combinations as our clinical data mature. We are also beginning to explore the potential of TDO inhibitors as stand-alone therapy and in combination with IDO inhibitors."
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 that represent potential breakthrough approaches to cancer therapy. The IDO pathway regulates immune response by suppressing T-cell activation which enables 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 whose expression of TAAs might otherwise be recognized and attacked by the immune system. NewLink has a number of active programs directed at synthesizing inhibitors to the IDO pathway and additionally has discovered novel tryptophan-2,3-dioxygenase (TDO) specific inhibitors that are potential anti-cancer compounds which could function individually or in combination with IDO inhibition.
