AMES, Iowa, July 31, 2018 (GLOBE NEWSWIRE) -- NewLink Genetics Corporation (NASDAQ:NLNK) today announced its clinical plan and strategy, reported consolidated financial results for the second quarter of 2018, and revised its cash guidance.

In early April, the Company announced a review of its clinical programs involving its lead immuno-oncology candidate, indoximod.  This extensive review included an evaluation of available data from clinical trials sponsored by other companies, potential combination therapies with indoximod, and unmet medical need. Based on these key criteria, NewLink Genetics has focused its indoximod clinical programs on recurrent pediatric brain tumors, front-line treatment of diffuse intrinsic pontine glioma (DIPG), and front-line treatment of acute myeloid leukemia (AML). In addition, the company will continue to advance NLG802, the prodrug of indoximod with significantly higher pharmacokinetic exposure seen in preclinical research.

• Presented abstract 10973 entitled, Front-line therapy of DIPG using the IDO pathway inhibitor indoximod in combination with radiation and chemotherapy, during a plenary session at the American Association of Cancer Research (AACR) 2018 Annual Meeting in April, reporting on six newly diagnosed DIPG patients all of whom had completed induction radio-immunotherapy. Treatment was well tolerated with symptomatic improvement in all 6 patients. Site-reported radiographic review indicated near resolution of tumor in one patient at the end of radiotherapy and observable improvement in 5 out of 6 patients overall. A seventh patient with progressive DIPG received reirradiation combined with indoximod, which was well tolerated with symptomatic improvement and objective tumor reduction per site-reported assessment on post-treatment MRI.
• Presented abstract 3753 entitled, Indoximod modulates AhR-driven transcription of genes that control immune function, at the 2018 AACR Annual Meeting in April.  Reported data show indoximod reverses the effects of low tryptophan by increasing proliferation of effector T cells, directly reprograms T regulatory cells into helper T cells and also downregulates IDO expression in dendritic cells, further supporting indoximod's differentiated mechanism of action.
• Presented abstract 9512 entitled, Phase 2 trial of the IDO pathway inhibitor indoximod plus checkpoint inhibition for the treatment of patients with advanced melanoma, at the American Society of Clinical Oncology (ASCO) 2018 Annual Meeting in June, demonstrating an Overall Response Rate (ORR) of 55.7% and a Complete Response (CR) of 18.6% which compares favorably to historical PD-1 monotherapy data.
• Presented abstract 4015 entitled, Phase 2 trial of the IDO pathway inhibitor indoximod plus gemcitabine / nab-paclitaxel for the treatment of patients with metastatic pancreas cancer, at the 2018 ASCO Annual Meeting in June, demonstrating a median Overall Survival (mOS) of 10.9 months and an Overall Response Rate (ORR) of 46.1%. The combination demonstrated potentially promising activity that correlated with a measurable immune response.
• Presented a poster entitled, Radio-immunotherapy using the IDO pathway inhibitor indoximod for children with newly-diagnosed DIPG at the International Symposium of Pediatric Neuro-Oncology (ISPNO) 2018 Annual Meeting in July.  The updated Phase 1 data showed that all (10/10) front-line treatment DIPG patients, including the 6 patients previously presented at 2018 AACR Annual Meeting, demonstrated initial symptomatic improvement, and eight of ten had completed radiation, with the remaining 2 of 10 patients continuing radiotherapy. Currently, 9/10 patients remain on study, with the longest time on study of 8.5 months at the time of the report.

R&D Expenses: Research and development expenses for the second quarter of 2018 were $12.1 million, a decrease of $6.1 million from $18.2 million for the same period in 2017.  The decrease was due primarily to a decrease of $5.6 million in contract research and manufacturing spend, a decrease of $1.1 million in personnel-related and stock compensation expense, a $311,000 decrease in supplies, offset by an increase of $741,000 in clinical trial expense and an increase of $128,000 in legal and consulting expense.

Indoximod is an investigational, orally available small molecule targeting the IDO pathway. The IDO pathway is a key immuno-oncology target, suppressing immune response and allowing for immune escape by degrading tryptophan with the resultant production of kynurenine.  We hypothesize that immune activation using indoximod based combination immunotherapy can allow responsiveness to chemotherapy and radiation in patients who may otherwise be refractory or have limited benefit. The immuno-stimulatory effects of indoximod impact four main cell types: CD8+ T cells, CD4+ T helper cells, T regulatory cells, and dendritic cells. Indoximod reverses the effects of low tryptophan by increasing the proliferation of CD8+ effector T cells, drives differentiation into CD4+ T helper cells rather than regulatory T cells, and downregulates IDO expression in dendritic cells. Indoximod is being evaluated in combination with treatment regimens including chemotherapy, radiation, checkpoint blockade and cancer vaccines across multiple indications including recurrent pediatric brain tumors, DIPG, and AML.

NewLink Genetics is a clinical stage biopharmaceutical company focusing on discovering, developing and commercializing novel immuno-oncology product candidates to improve the lives of patients with cancer. NewLink Genetics' IDO pathway inhibitors are designed to harness multiple components of the immune system to combat cancer.
