TEL-AVIV, Israel,, Feb. 13, 2017 (GLOBE NEWSWIRE) — RedHill Biopharma Ltd. (NASDAQ:RDHL) (TASE:RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company primarily focused on the development and commercialization of late clinical-stage, proprietary, orally-administered, small molecule drugs for gastrointestinal and inflammatory diseases and cancer, today announced  enrollment of the last patient in the Phase III study with BEKINDA® 24 mg for the treatment of acute gastroenteritis and gastritis (the GUARD study).

The randomized, double-blind, placebo-controlled Phase III GUARD study with BEKINDA® 24 mg is conducted in 29 U.S. clinical sites and treated 320 adults and children over the age of 12 who suffered from acute gastroenteritis and gastritis. Top-line results are expected in the second quarter of 2017.

Robert A. Silverman, MD, MS, Emergency Medicine specialist at the Hofstra North Shore-LIJ Medical Center, and Associate Professor at the Hofstra North Shore-LIJ School of Medicine in New York, is the lead investigator for the study.

BEKINDA® is a proprietary, bimodal extended-release, once-daily oral pill formulation of the antiemetic drug ondansetron, targeting multiple gastrointestinal indications. BEKINDA® is intended to provide patients with relief from nausea and vomiting symptoms for a full 24-hour period with a single oral tablet.

The primary endpoint for the GUARD study is the absence of vomiting or the need for rescue medications or intravenous hydration from 30 minutes through 24 hours after the first dose of the study drug. Secondary endpoints include, among others, frequency of vomiting, severity and time to resolution of nausea and time to resumption of normal activities.

As previously announced, in light of discussions with the U.S. Food and Drug Administration (FDA), RedHill believes that, subject to achieving highly significant positive results, the Phase III GUARD study may be sufficient as a single Phase III study to support potential future marketing application in the U.S., conditional upon, among other things, future review and guidance from the FDA.

Acute gastroenteritis and gastritis are inflammations of the mucus membranes of the gastrointestinal tract leading to a combination of symptoms which include nausea, vomiting, diarrhea or abdominal pain. Acute gastroenteritis is a common infectious disease, with approximately 179 million cases annually in the U.S.1. It is caused by many different infectious agents, most commonly by viral infections, accounting for up to 70% of cases. Noroviruses cause the most outbreaks of non-bacterial acute gastroenteritis in all age groups and often occur in epidemic outbreaks in schools, nursing homes and other group settings2. Gastroenteritis and gastritis are major causes of emergency room visits, with up to 474,000 estimated hospitalizations annually in the U.S. alone1. Dehydration is the most frequent and dangerous complication of acute gastroenteritis3. Oral rehydration is the preferred therapy in mild to moderate dehydration, whereas intravenous fluids are recommended in more severe cases4. Adding ondansetron, the active ingredient in BEKINDA®, to the standard intravenous rehydration therapy has shown to significantly reduce the amount of vomiting in children with gastroenteritis3, however, to the best of RedHill’s knowledge, its efficacy in adults has not been studied in a randomized clinical trial in the U.S.

Ondansetron is used as an antiemetic in patients suffering from chemotherapy and radiotherapy-induced nausea and vomiting and from postoperative nausea and vomiting5. BEKINDA® may decrease the frequency of vomiting, improve the success and compliance of oral rehydration therapy and decrease the rate of intravenous therapy in patients suffering from gastroenteritis. It may also decrease the number of emergency room visits, and therefore reduce health care costs. If approved for marketing by the FDA, BEKINDA® could become the first 5-HT3 antiemetic drug in the U.S. indicated for the treatment of acute gastroenteritis and gastritis, targeting a potential worldwide market estimated to exceed $650 million annually6.

BEKINDA® is being studied for additional indications. A randomized, double-blind, placebo-controlled Phase II study with BEKINDA® 12 mg is currently ongoing in the U.S. for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D). The Phase II study is evaluating the safety and efficacy of BEKINDA® 12 mg in adults over the age of 18 who suffer from IBS-D at 16 clinical sites in the U.S. 96 of the planned total of 120 subjects have been enrolled to date. Top-line results are expected in mid-2017.

The Phase III GUARD study and the Phase II study with BEKINDA® are registered on www.ClinicalTrials.gov, a web-based service of the U.S. National Institutes of Health, which provides access to information on publicly and privately supported clinical studies.

Once known as a “financial wizard”, Indian-born Rakesh Saxena now faces decades in jail for a Thai banking scandal that triggered the 1997 Asian financial crisis. Following a legal battle that dragged on for 26 years, the Supreme Court on September 12 finally sentenced Saxena to 335 years in jail over three lawsuits stemming from the Bangkok Bank of Commerce (BBC) embezzlement scandal. Although the jail sentence of over three centuries was upheld, the 70-year-old will serve only 20 years behind bars, the maximum term under the Thai Penal Code. Working his way up the ladder From 1974 to 1985, Saxena worked as a foreign exchange dealer and money market broker in India, Singapore, Hong Kong, and London. He later moved to Thailand to work as a newspaper financial columnist and consultant to financial institutions. In 1989, while living in Bangkok, he met and befriended Krirkkiat Jalichandra, who had just been appointed as the BBC’s senior vice-president. In 1992, Saxena became a personal advisor to Krirkkiat, who had since been promoted to BBC president. The bank at that time was owned by the family of Krirkkiat’s mother. In his book “BBC Truth”, Krirkkiat wrote that his maternal grandfather, the late former prime minister MR Kukrit Pramoj, had told him: “You have to help with Granddad’s work at the bank.” Krirkkiat had earlier worked at the Bank of Thailand for over a decade. How the scandal unfolded Between 1993 and 1994, the bank spent over 36 billion baht on business takeovers and leveraged buyouts linked with Saxena. The BBC also granted loans with insufficient or overpriced collateral to companies controlled by Saxena, senior bank executives including Krirkkiat, and their associates – many of whom were politicians. The BBC scandal was linked to a clique of young politicians known as the “Group of 16”, many of whom went on to become political heavyweights. Regulators estimated the bank’s bad loans at over 50 billion baht or roughly 40 percent of its assets. Saxena claimed years later that in 1995, BBC officials concealed the number of non-performing loans by lending money to bank-owned shell companies so they could repay debts owed by other borrowers. After the scheme was uncovered, the central bank in February 1996 ordered Krirkkiat to not renew Saxena’s consulting contract. A bank’s collapse Just a month later, the Bank of Thailand took control of the BBC. During a censure debate in early May 1996, opposition MPs from the Democrat Party accused unnamed government politicians of colluding with Saxena and Krirkkiat to “embezzle at least 50 billion baht from the bank’s deposits”. The accusation, coupled with reports of the bank’s deteriorating condition, led to a run on BBC deposits of more than 30 billion baht. That prompted a takeover by the Finance Ministry, which allowed the bank to go bust in August 1998 after discovering an unmanageable level of insolvency. Krirkkiat, Saxena and several others faced 17 court cases on charges of embezzlement and fraud causing damage of over 50 billion baht. The disgraced BBC president was sentenced to 20 years in jail and fined 3.1 billion baht. Krirkkiat died in October 2012 while still serving his prison sentence. Fallout for the economy The BBC scandal led to the closure of a Thai bank that had been operating for over 50 years. Its collapse undermined confidence in the Thai financial system, leading to a domino effect that toppled 56 financial institutions and saw many Thai commercial banks taken over by foreign investors. In July 1997, the Thai government gave in to speculative pressure against the baht and devalued the currency. The move forced neighboring countries to follow suit with their currencies, triggering a financial crisis that swept across Asia. Long legal battle In June 1996, Saxena was in Canada when Thai authorities charged him and others in connection with the BBC scandal. He was arrested a month later but resisted extradition from Canada, claiming he would be killed if he was sent back to Thailand. The extradition battle began in June 1997. More than a decade later, in October 2009, the Supreme Court of Canada ruled against Saxena and he was turned over to Thai authorities. In Thailand, Saxena waged a three-decade legal battle that came to an end this month with a final Supreme Court ruling that sealed his fate. Source: Thai Public Broadcasting Service
