CYTOVIA Inc., IMMUNE Pharma’s Oncology Subsidiary, Announces the Publication of New Results in the British Journal of Haematology and Filing of a World-wide Patent Protecting the Use of Ceplene® in Chronic Myeloid Leukemia (CML)

Strengthens Intellectual property portfolio and expands potential clinical use and market opportunity

NEW YORK--()--Cytovia, the oncology subsidiary of Immune Pharmaceuticals (NASDAQ:IMNP) ("Immune" or the “Company”), a clinical stage biopharmaceutical company, today announced the publication of new results supporting the benefits of its lead compound Ceplene® (histamine dihydrochloride). In parallel, Cytovia has filed a world-wide patent to protect the use of Ceplene® in CML. In the British Journal of Haematology new publication (https://www.ncbi.nlm.nih.gov/pubmed/28542840), the authors show that the genetic elimination of NOX2 function delayed the development of CML in mice and prolonged survival. These results support that Ceplene®, or other inhibitors of NOX2 function, may be efficacious in CML.

“We are interested in evaluating the potential efficacy of the combination of Ceplene® and low-dose IL-2 in CML patients.”

In the US, there are approximately 100,000 patients living with CML. The patients receive tyrosine kinase inhibitors including imatinib (Gleevec®, Glivec®), which have dramatically improved long-term survival. However, treatment with Gleevec® or other tyrosine kinase inhibitors is typically life-long with high medication costs and significant side-effects to therapy.

During treatment with tyrosine kinase inhibitors in CML, a small clone of leukemic cancer cells persists in most patients. Hence a method to further reduce or eliminate the burden of leukemic cancer cells would be of benefit to patients with CML.

“Inhibition of NOX2 is a novel and conceivable strategy to reduce the burden of malignant cells in patients with CML,” said Kristoffer Hellstrand, MD, PhD and professor of tumor immunology at the University of Gothenburg, Sweden. “We are interested in evaluating the potential efficacy of the combination of Ceplene® and low-dose IL-2 in CML patients.”

Dr. Daniel Teper, CEO of Cytovia adds: “We are delighted of the renewed scientific interest in Ceplene as demonstrated by the high quality data published in peer reviewed journals and the new patent filings. The spin-off of Cytovia from Immune will provide us the focused resources to commercialize Ceplene in AML, initiate clinical studies in new indications, including CML, and potentially expand Ceplene market opportunity.”

About Ceplene

Ceplene® (histamine dihydrochloride) is an immunostimulant that is approved for use in over 30 countries in Europe for the maintenance of first remission in patients with acute myeloid leukemia (AML). Ceplene® is administered in conjunction with low-dose IL-2 for enhanced activation of anti-tumor immunity. Specifically, Ceplene® acts by countering NOX2-mediated immunosuppression and thus improves activation of anti-tumor lymphocytes such as T cells and NK cells. When administered together with the T cell/NK cell activator IL-2, Ceplene® promotes immune-mediated killing of cancer cells, thus providing a strong pharmacological rationale for this combination immunotherapy. Aspects on the effects of Ceplene® on anti-tumor immunity have been reported in over 50 scientific articles.

In an international Phase III clinical study in 320 AML patients, the combination of Ceplene® and low-dose IL-2 has been shown to prevent relapse of leukemia while maintaining good quality of life during treatment. A recent Phase IV study in 84 AML patients demonstrated efficient activation of anti-tumor immunity during treatment with Ceplene®/IL-2 and also identified tools that may prognosticate the clinical benefit of the treatment. During 2015-17, detailed results of the Phase IV study were presented in several medical journals including Leukemia, a leading journal in hematology. Following the recent acquisition from Mylan, Cytovia holds worldwide rights for Ceplene®.
