$IMNP Provides Update to Proposed Pint Pharma Transaction

NEW YORK, June 29, 2017 — Immune Pharmaceuticals Inc. (NASDAQ: IMNP) (the “Company”) announced today that its oncology subsidiary, Cytovia Inc. (“Cytovia”) has reached substantial agreement on the material terms of a licensing and commercialization agreement of Ceplene® in Latin America with Pint Pharma S.A. (“Pint”), a private specialty pharmaceutical company with extensive experience in the pharmaceutical sector throughout Latin America.  As previously announced by us on April 20, 2017, the Company had entered into a letter of intent with Pint, which provided that the parties would use their best efforts to reach agreement regarding the terms of an exclusive license which would provide Pint the rights to commercialize Ceplene^® throughout Latin America, including Argentina, Brazil, Chile, Colombia and Mexico within 60 days. The parties currently anticipate that they will execute a definitive licensing agreement within the next five to seven business days.

The parties have agreed that Pint will be responsible for the registration and commercialization of Ceplene^® in Latin American countries, and that Pint will base its registration application on the existing European marketing authorization for Ceplene^®. Commercialization activities include registration, pricing and reimbursement, and sales and marketing activities. The definitive agreements will provide for sales based milestones as well as product supply pricing schedules, which will provide appropriate economics to our subsidiary, Cytovia.

In addition, the parties have agreed to enter into a definitive agreement related to Pint’s commitment to invest $4 million into Cytovia at terms similar to other investors in the same financing round and upon satisfaction of certain conditions precedent. Dr. Massimo Radaelli, Executive Chairman of Pint, will join the board of directors of Cytovia following completion of the investment.

Dr. Daniel Teper commented, “I am pleased to confirm the substantial progress made in this regard and look forward to a partnership with Pint for Latin America markets, which follows our acquisition of the remainder of worldwide Ceplene^® rights from Mylan. Our strategic plan is to commercialize Ceplene^® in combination with low dose IL-2 in all markets that accept the European registration dossier as a basis for approval.  We also plan to pursue approval of Ceplene^® in the United States based on the previously announced global overall survival study, REMAIN”.

“We are very excited about the partnership with Immune and its subsidiary, Cytovia, an emerging global bio-pharmaceutical company focused on the development of immuno-oncology drugs. Providing Ceplene^® to patients with Acute Myeloid Leukemia (AML) in the Latin America region is an important milestone and expands Pint’s robust oncology pipeline”, added David Munoz, CEO of Pint.

Currently, Ceplene^® is the only drug approved in 30 European countries and Israel for the maintenance of first remission in Acute Myeloid Leukemia (AML). It is administered in combination with interleukin-2 (IL-2). Given the significant unmet need (~10,000 newly diagnosed AML patients a year in Latin America) and no alternative drugs in the remission setting, Pint and Cytovia strongly believe in the importance of launching the combination of Ceplene^® and IL-2 in Latin American countries.

About Ceplene^®

Ceplene^® (histamine dihydrochloride) is administered in conjunction with low dose interleukin-2 (IL-2), for maintenance of first remission in patients with Acute Myeloid Leukemia (AML). It has been shown in clinical studies to prevent leukemic relapses in AML patients in first remission and prolong leukemia-free survival, while maintaining good quality of life during treatment.  Ceplene^® acts by enhancing the immunostimulatory effect of IL-2 and countering reactive oxygen species-induced dysfunction and apoptosis of T and NK cells, thereby inducing immune-mediated killing of leukemic cells, providing a strong rationale for this combination therapy. A recent Phase IV study presented at the meeting of the American Association for Cancer Research in 2016 confirmed the safety and efficacy of Ceplene^® in the international study that supported European approval.

About Acute Myeloid Leukemia (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 (75-80%) of adult patients will experience a relapse of leukemia, with a survival prognosis of 33% in younger patients 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. The prognosis following first remission is poor and there are no other effective remission therapies currently available. AML represents an orphan condition with high unmet need.
