  • The randomized, double-blind, placebo-controlled Phase III study with RHB-102 for acute gastroenteritis and gastritis (the GUARD study) is underway in the U.S., with a planned enrollment of 320 patients
  • Top-line results from the Phase III GUARD study are expected during H2/2015

TEL-AVIV, Israel, Dec. 17, 2014 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq:RDHL) (TASE:RDHL) ("RedHill"), an Israeli biopharmaceutical company focused on late clinical-stage drugs for inflammatory and gastrointestinal diseases, including gastrointestinal cancers, today announced that the first patients have been enrolled in the Phase III clinical study of RHB-102 (BEKINDA) for acute gastroenteritis and gastritis (the GUARD study), inflammations of the gastrointestinal tract which cause, among other symptoms, nausea and vomiting. RHB-102 is a proprietary, extended-release, once-daily oral pill formulation of the antiemetic drug ondansetron.

Top-line results from the Phase III GUARD study are expected during the second half of 2015 and are intended to support potential future submissions of marketing applications in both the U.S. and Europe for this indication. If approved for marketing by the FDA, RHB-102 could become the first 5-HT3 antiemetic drug indicated for the treatment of acute gastroenteritis and gastritis, targeting a potential worldwide market estimated to exceed $650 million annually1.

Dr. Reza Fathi, PhD, RedHill's Senior VP R&D noted: "We are very pleased with the enrollment of the first patients in the Phase III GUARD study of RHB-102 for this important new indication. Gastroenteritis and gastritis are very common conditions, with over 179 million cases annually in the U.S. alone, and there is a significant need to provide patients with new treatment options. RHB-102 is intended to provide patients with relief from nausea and vomiting symptoms for a full 24 hour period with a single oral tablet and could also reduce the burden on health systems by reducing hospital readmissions."

In parallel to the Phase III GUARD study in acute gastroenteritis and gastritis, RedHill is pursuing marketing approval for RHB-102 for the indications of chemotherapy and radiotherapy-induced nausea and vomiting ("CINV" and "RINV" respectively) in Europe and the U.S. RedHill submitted a European Marketing Authorization Application (MAA) for RHB-102 for these indications, under the brand name BEKINDA, in December 2014. Following a pre-New Drug Application (pre-NDA) meeting with the U.S. Food and Drug Administration (FDA) regarding the development of RHB-102 for CINV prevention, and in light of FDA's feedback, RedHill provided the FDA with supplementary information and is currently awaiting the FDA's response. Along with the data generated from prior studies, RedHill plans on using post-marketing data from Europe to further support a potential submission of a U.S. NDA for RHB-102 for CINV.

About the Phase III GUARD study:

The randomized, double-blind, placebo-controlled, parallel group Phase III GUARD study for RHB-102 (BEKINDA) is being conducted in the U.S. with a planned enrollment of 320 adults and children over the age of 12 who suffer from acute gastroenteritis or gastritis. The primary endpoint for the study is the absence of vomiting commencing 30 minutes after administration of the first dose through emergency room discharge. Secondary endpoints include frequency of vomiting, severity and time to resolution of nausea, and time to resumption of normal activities. Top-line results from the study are expected during the second half of 2015.

The GUARD Phase III study is registered on www.ClinicalTrials.gov, a web-based service by the U.S. National Institute of Health which provides public access to information on publicly and privately supported clinical studies.
