IMMUNE Pharmaceuticals' Oncology Subsidiary, CYTOVIA, Announces Additional Clinical Trial Results on the Efficacy of Ceplene® in Combination with Low-Dose IL-2 in Patients With Acute Myeloid Leukemia, Recently Published in Leukemia, a Leading Hematology Journal


Sixty-seven per cent of patients with functional natural killer (NK) cells remained disease-free at a pre-determined end point that followed two years of treatment

NEW YORK, July 5, 2017 /PRNewswire/ -- Cytovia, the oncology subsidiary of Immune Pharmaceuticals Inc., a clinical stage biopharmaceutical company (NASDAQ:IMNP) ("Immune" or the "Company") announced the publication of clinical trial results on the use of Ceplene (histamine dihydrochloride) for relapse prevention in patients with acute myeloid leukemia (AML). The results were published in the leading hematology journal, Leukemia, published by Springer Nature. Investigators from the Universities of Gothenburg, Sweden and Rome, Italy reported that functional NK cells are clinically relevant anti-leukemic effector cells in AML patients who received treatment with Ceplene/IL-2.

Specifically, the investigators identified that approximately 60% of the AML patients who had received treatment with Ceplene/IL-2 harbored NK cells that were potentially reactive with the patient's leukemic cells. The "Re:Mission" phase IV trial results showed that 67% of patients with functional, autoreactive NK cells remained relapse-free for a pre-scheduled follow-up of 2 years vs. 11% relapse-free survival in corresponding patients devoid of active NK cells (p=0.0002, n=39). The results were based on analyses of the "Re:Mission" phase IV trial in AML, in which adult patients received Ceplene and low-dose IL-2 to prevent life-threatening relapses. For details of the trial design, please visit https://clinicaltrials.gov/ct2/show/NCT01347996?term=ceplene&rank=1.

"These results imply that potentially a large proportion of AML patients harbor efficacious anti-leukemic NK cells that are activated during immunotherapy with Ceplene in combination with low- dose IL-2. Additionally, NK cell profiling may contribute to optimally select patients who are suitable for treatment", said Fredrik Bergh Thorén, PhD, senior author of the Leukemia paper.

Cytovia's Dr. Daniel Teper added: "We are impressed by the quality of new scientific and clinical data, which further supports the relevance of Ceplene/IL-2 treatment for AML patients post first remission in preventing potentially life-threatening relapses of leukemia. Immune/Cytovia has been granted orphan drug designation for the use of Ceplene in combination with low-dose IL-2 in AML and is eligible for protocol assistance, potential R&D grants, waived FDA fees, tax credits and seven-year market drug exclusivity following approval in the United States."

Most patients with AML achieve complete remission from leukemia after receiving chemotherapy. However, the majority of adult patients experience relapse of AML, with poor prospects of long-term survival. Ceplene used in conjunction with low-dose Proleukin (interleukin-2) has been developed to prevent relapses in the post-chemotherapy phase of AML. A previous phase III trial in 320 patients confirmed the efficacy of Ceplene/IL-2 in preventing relapse of AML.

Ceplene in combination with low-dose IL-2 has been approved in more than 30 countries in Europe and in Israel for the treatment of AML and for maintenance of remission and prevention of relapse of leukemia. Currently, there are no approved therapies to prevent relapse for the vast majority of AML patients. An international Overall Survival study, REMAIN, is planned to support approval in the United States.

About Ceplene  

Ceplene (histamine dihydrochloride) is an immunostimulant that is administered in conjunction with low-dose interleukin-2 for maintenance of first remission in patients with AML. Ceplene has been shown in an international phase III clinical study to prevent relapse of leukemia in AML patients in first remission while maintaining good quality of life during treatment. Ceplene acts by countering dysfunction and apoptosis of T and NK cells, thereby inducing immune-mediated killing of leukemic cells, providing a strong pharmacological rationale for this combination therapy. A Phase IV study presented at the meeting of the American Association for Cancer Research in 2016 supported the safety and efficacy of Ceplene as demonstrated in the international phase III study. As previously announced, Immune, through its oncology subsidiary, Cytovia, entered into an Asset Purchase Agreement on June 15, 2017 with Meda Pharma SARL, a Mylan N.V. company, to repurchase the remaining worldwide rights to Ceplene which it did not own previously.

About AML   

AML patients receive intensive induction treatment with chemotherapeutic drugs at diagnosis and typically become free of detectable leukemia, achieving "complete remission". However, within 1-2 years the majority of adult patients will experience a relapse of leukemia, of which the prognosis for survival is 33% in patients' younger than 60 years of age and 15-20% in patients over 60 years of age. According to the American Cancer Society, there will be approximately 21,380 new cases of AML and 10,590 deaths from AML in the US in 2017. AML represents an orphan indication with a particularly high unmet medical need.
