NewLink Genetics Receives Notice of Allowance from USPTO Covering Indoximod Salts and Prodrugs

AMES, Iowa, July 10, 2017 (GLOBE NEWSWIRE) -- NewLink Genetics Corporation (NASDAQ:NLNK) today announced that it has received a Notice of Allowance for U.S. patent application number 15/171,031 from the United States Patent and Trademark Office (USPTO) covering claims to the salts and prodrugs of indoximod (1-methyl-D-tryptophan). Indoximod is Newlink's orally bioavailable, small molecule targeting the IDO pathway with a distinct mechanism of action.  

"We are delighted to hear this positive news from the U.S. patent office," said Charles J. Link, Jr., M.D., Chief Executive Officer of NewLink Genetics. "Indoximod continues to make significant progress in the clinic with promising data across multiple indications. This decision by the U.S. patent office represents a key milestone in the alignment of indoximod's global patent strategy with our clinical development path."

Upon issuance, the new patent will provide NewLink with intellectual property protection covering the compounds and pharmaceutical compositions comprised of salts and prodrugs of indoximod.

"We believe indoximod's promising clinical activity and favorable safety profile, coupled with its differentiated mechanism of action, position indoximod as a key molecule to be considered in IO combinations," said Nicholas Vahanian, M.D., Chief Medical Officer of NewLink Genetics. "We are excited in our upcoming pivotal trial in metastatic melanoma and allowances of these patents align well with our strategy. Additionally, the preclinical data we presented in April at the AACR Annual Meeting illustrated how NLG802, which is our prodrug of indoximod and a new chemical entity, increased the plasma concentrations of indoximod."

This Notice of Allowance concludes the substantive examination of our patent application and will result in the issuance of a U.S. patent after administrative processes are completed. The U.S. patent scheduled to issue from this application will expire in 2036.
