Hyperion Therapeutics and Clal Biotechnology Industries Ltd. Enter Into Interim Agreement

South San Francisco, California, UNITED STATES

BRISBANE, Calif. and RAMAT GAN, Israel, Oct. 7, 2014 (GLOBE NEWSWIRE) -- Hyperion Therapeutics, Inc. (Nasdaq:HPTX) ("Hyperion") and Clal Biotechnology Industries Ltd. (TASE:CBI) ("CBI") today announced that they have entered into an interim agreement in order to attempt to resolve the disputes between them and to allow CBI to evaluate whether there is any clinical efficacy to, and whether there is a potential regulatory path forward for, DiaPep277 that a party other than Hyperion may wish to pursue.

Under the terms of the interim agreement, and consistent with Hyperion's statement of September 8, 2014, Hyperion will complete the current DIA-AID 2 study of DiaPep277, at its expense. An independent party or parties will be appointed by CBI, at CBI's expense, and will be permitted to have access to relevant non-privileged documentary materials including, the statistical analysis plans, the study dataset after unblinding, and any correspondence with the FDA and other medical/clinical regulatory entities. The independent party is expected to assess, for CBI's benefit, the ongoing conduct of the DIA-AID 2 study, the conduct of the completed DIA-AID 1 study, the integrity of the studies' readouts, and any potential regulatory path forward for DiaPep277. The assessment shall be conducted during the DIA-AID 2 study and thereafter for as long as reasonably required to complete the review. Hyperion will not be obligated to take any action in response to the independent party's observations.

During the interim period (until October 31, 2014, which may be extended by either party for an additional period of 3 weeks), Hyperion and CBI have agreed to not take any additional steps to prosecute any lawsuit, claim, or other litigation against the other party relating to the development of DiaPep277 or the Share Purchase Agreement regarding Andromeda Biotech, Ltd., which Hyperion acquired from CBI in June 2014. Hyperion and CBI have further agreed that by virtue of the interim agreement, neither party has waived any right, claim or defense relating to the above-mentioned Share Purchase Agreement.
