Denileukin diftitox is under clinical development by Citius Pharmaceuticals and currently in Pre-Registration for Cutaneous T-Cell Lymphoma. According to GlobalData, Pre-Registration drugs for Cutaneous T-Cell Lymphoma have an 88% phase transition success rate (PTSR) indication benchmark for progressing into Marketed. GlobalData’s report assesses how Denileukin diftitox’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

Denileukin diftitox overview

Denileukin diftitox (Ontak, Remitoro) is a recombinant DNA-derived cytotoxic protein, composed of the amino acid sequences for diphtheria toxin fragments A and B (Met 1-Thr 387)-His followed by the sequences for interleukin-2 (IL-2; Ala 1-Thr 133), produced in an E. coli expression system, acts as anti-neoplastic agent. It is formulated as solution and powder for solution for intravenous and intravenous drip route of administration. Ontak is indicated for the treatment of patients with persistent or recurrent cutaneous T-cell lymphoma whose malignant cells express the CD25 component of the IL-2 receptor. Remitoro is indicated for the treatment of relapsed or refractory Peripheral T-cell Lymphoma (PTCL) and relapsed or refractory Cutaneous T-cell Lymphoma (CTCL).

Ontak (denileukin diftitox, E7272, E7777) is under development for the treatment of mycosis fungoides [MF] or Sezary Syndrome, solid tumors including cutaneous melanoma, non-small cell lung cancer, renal cell carcinoma, endometrial cancer and epithelial ovarian cancer. The drug candidate was also under development for the treatment of cutaneous T-cell lymphoma, metastatic malignant melanoma, B-cell chronic lymphocytic leukemia (CLL), pancreatic cancer, post autologous transplantation, B-cell non-Hodgkin lymphoma, diffuse large B-cell lymphoma, follicular lymphoma, small lymphocytic lymphoma and transformed B-cell lymphoma.
