AMES, Iowa, June 23, 2017 (GLOBE NEWSWIRE) -- NewLink Genetics Corporation (NASDAQ:NLNK) today announced the presentation of data from the Phase 1b portion of a study of indoximod, an IDO pathway inhibitor, in combination with idarubicin and cytarabine for patients with newly diagnosed acute myeloid leukemia (AML).  Abstract E-912, Indoximod in Combination with Idarubicin and Cytarabine for Upfront Treatment of Patients with Newly Diagnosed Acute Myeloid Leukemia (AML): Phase 1 Report, is being presented by Ashkan Emadi, M.D., Ph.D., Associate Professor of Medicine at the University of Maryland Greenebaum Comprehensive Cancer Center, during the European Hematology Association (EHA) Congress in Madrid, Spain on Friday, June 23, 2017, 9:30 AM to Saturday, June 24, 7:00 PM CET.

These data indicate indoximod does not appear to add significant toxicity to standard therapy for patients with newly diagnosed AML, and no regimen-limiting toxicities (RLT) have been observed to date. Initial data show that the morphological complete remission (CR) rate is as expected after one cycle of induction chemotherapy.  Seven of seven patients who achieved CR were found to have no minimal residual disease (MRD-neg). 

“While from a small number of patients, these data show an encouraging MRD negativity rate and may offer the potential for measurable clinical benefits for patients,” said Dr. Emadi, Principal Investigator of this study.
