Fennec Provides Corporate Update and Announces First Quarter 2016 Results

RESEARCH TRIANGLE PARK, NORTH CAROLINA--(Marketwired - May 12, 2016) - Fennec Pharmaceuticals Inc. (FRX.TO)(FENCF), a specialty pharmaceutical company focused on the development of Sodium Thiosulfate (STS) for the prevention of platinum-induced ototoxicity in pediatric patients, today reported its corporate update and financial results for the first quarter ended March 31, 2016.

Corporate Update

As previously reported, interim results from ""SIOPEL 6: A multi-centre open label randomised phase III trial of the efficacy of sodium thiosulfate (STS) in reducing ototoxicity in patients receiving cisplatin (Cis) monotherapy for standard risk hepatoblastoma (SR-HB)" has been accepted for an oral presentation at the 2016 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, Illinois. Penelope Brock, MD, PhD, FRCPCH, International Chair of SIOPEL will present "Two year results of clinical efficacy of cisplatin in combination with sodium thiosulfate (STS) vs cisplatin alone in a randomized phase III trial for standard risk hepatoblastoma (SR-HB): SIOPEL 6," in an oral presentation on June 5, 2016 at ASCO.

"The recently announced financing by Sigma Tau Finanziaria provides Fennec with the necessary funds to support the development of STS through 2017 and we look forward to the presentation of updated data from the Siopel 6 study at ASCO and ultimately inclusion of the final results in to our forthcoming regulatory submissions" said Rosty Raykov, Fennec's CEO.

Fennec also announces that it has entered into an agreement with Elion Oncology, LLC involving the transfer by Fennec of certain intellectual property, data and other assets relating to Eniluracil and Adh-1 technologies and development programs to Elion. .

Eniluracil (EU) is an oral irreversible dihydropyrimidine dehydrogenase (DPD) inhibitor, the enzyme responsible for rapidly breaking down 5-FU. Eniluracil was previously under development by GlaxoSmithKline ("GSK"), and we licensed the compound from GSK in July 2005. Adh -1 is an anti-cancer drug that selectively targets N-cadherin present on certain tumor cells and the established blood vessels that supply tumors. Fennec is focused on the development of STS and does not currently have the resources to also pursue the Eniluracil and ADH-1 programs. Accordingly, as previously disclosed, we have concluded that it would be in the best interests of our shareholders and the cancer community to focus on seeking a partnership for Eniluracil and Adh -1.

If the transaction is completed, Fennec will receive US$40,000 on closing and continuing revenue share payments of 5% of the gross revenues derived from the sold assets until the last to expire patents forming part of such assets. The value for such assets has been determined by negotiations between Elion and Fennec. In addition to shareholder approval at the Company's annual and special shareholder meeting to be held on June 8, 2016, completion of the sale is subject to a number of closing conditions. Some of such conditions, including a satisfactory review by Elion of the assets proposed to be transferred, are outside of our control. Accordingly, the transaction may not close even if approved by our shareholders at our upcoming shareholder meeting.
