Citius Pharmaceuticals Inc. on Wednesday said it filed for U.S. Food and Drug Administration approval of its lead product candidate denileukin diftitox, also known as I/Ontak, for the treatment of patients with persistent or recurrent cutaneous T-cell lymphoma.

The Cranford, N.J., biopharmaceutical company said I/Ontak is a purified and more bioactive formulation of Ontak, which Japan's Eisai Co. pulled from the market in 2014 due to production issues related to bacterial expression and purification challenges.

Citius last year acquired the exclusive license to denileukin diftitox a late-stage oncology immunotherapy for the treatment of cutaneous T-cell lymphoma, a rare form of non-Hodgkin lymphoma.

The company said manufacturing improvements have resulted in a new formulation that features improved purity and bioactivity.
