RedHill Biopharma Announces EnteraGam® Poster Presentation at the ISPOR 20th Annual European Congress

TEL-AVIV, Israel and RALEIGH, N.C., Nov. 06, 2017 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (NASDAQ:RDHL) (Tel-Aviv Stock Exchange:RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company primarily focused on late clinical-stage development and commercialization of proprietary drugs for gastrointestinal and inflammatory diseases and cancer, today announced a planned poster presentation relating to EnteraGam^® (serum-derived bovine immunoglobulin/protein isolate, SBI)¹, one of RedHill’s commercial products, at the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) 20^th  Annual European Congress, on Tuesday, November 7, 2017, from 09:45 AM – 1:30 PM (GMT), at the Scottish Event Campus in Glasgow, Scotland.

EnteraGam^® is a medical food intended for the dietary management of chronic diarrhea and loose stools, which must be administered under medical supervision. EnteraGam^® is one of three gastrointestinal products promoted by RedHill’s sales force in the U.S., together with Donnatal^® (Phenobarbital, Hyoscyamine Sulfate, Atropine Sulfate, Scopolamine Hydrobromide)² and Esomeprazole Strontium Delayed-Release (DR) Capsules 49.3 mg³.  RedHill licensed the exclusive U.S. rights to EnteraGam® from Entera Health Inc. (“Entera Health”).

The poster⁴, entitled “Economic and Clinical Impact of Serum-Derived Bovine Immunoglobulin / Protein Isolate (SBI) in the Management of Chronic Diarrhea in Inflammatory Bowel Disease (IBD)”, presents data from a pharmacoeconomic study conducted by Entera Health. The aim of the study was to evaluate the real-world economic and clinical impact of EnteraGam^® (SBI) use in patients suffering from IBD. The authors conclude that inclusion of EnteraGam^® for the management of chronic diarrhea in IBD can offer clinical benefits of overall disease management, while also lowering the overall cost to the healthcare system and patients, resulting in net savings primarily due to a reduction in utilization of high-cost prescription medications.

Numerous publications of clinical studies and retrospective chart reviews support the use of SBI in the dietary management of chronic diarrhea and loose stools⁵. The combined effect of SBI is intended to fulfill a distinctive nutritional requirement associated with various gastrointestinal conditions, where chronic diarrhea or loose stools are present and normal dietary proteins alone are insufficient. SBI has been shown in clinical studies to reduce loose stools and improve stool consistency as well as other symptoms, such as abdominal pain, bloating and urgency in patients with chronic diarrhea and loose stools⁶. Several studies in patients suffering from IBD, such as ulcerative colitis and Crohn’s disease, where SBI was given due to uncontrolled chronic diarrhea and loose stools, suggest that SBI improves management of chronic diarrhea and loose stools in patients who are refractory or partially responding to traditional therapies⁷. SBI has also been studied in patients with fecal incontinence with chronic diarrhea, in patients with celiac and non-celiac gluten sensitivity with chronic diarrhea and in additional gastrointestinal conditions⁸.

About EnteraGam^®:
EnteraGam^® (serum-derived bovine immunoglobulin/protein isolate, SBI) is a medical food product intended for the dietary management of chronic diarrhea and loose stools. EnteraGam^® must be administered under medical supervision. EnteraGam^® binds microbial components⁹, such as toxic substances released by bacteria that upset the intestinal environment. This helps prevent them from penetrating the lining of the intestine, which may contribute to chronic diarrhea and loose stools in people who have specific intestinal disorders¹⁰.

Safety Information about EnteraGam^®:
EnteraGam^® contains beef protein; therefore, patients who have an allergy to beef or any other component of EnteraGam^® should not take this product.  EnteraGam^® has not been studied in pregnant women, in women during labor and delivery, or in nursing mothers.  The choice to administer EnteraGam^® during pregnancy, labor and delivery, or to nursing mothers is at the clinical discretion of the prescribing physician.

EnteraGam^® does not contain any milk-derived ingredients such as lactose, casein or whey.  EnteraGam^® is gluten-free, dye-free and soy-free.

About Esomeprazole Strontium Delayed-Release Capsules 49.3 mg¹¹:
Esomeprazole Strontium Delayed-Release Capsules 49.3 mg is indicated for adults:

• for the short-term treatment (4-8 weeks) of heartburn and other symptoms associated with gastroesophageal reflux disease (GERD) and/or in healing and symptomatic resolution of erosive esophagitis (EE).
• to reduce the risk of stomach ulcers in some people taking non-steroidal anti-inflammatory drugs (NSAIDs) (controlled studies did not extend beyond 6 months).
• in combination with amoxicillin 1000 mg and clarithromycin 500 mg is indicated for the treatment of patients with a stomach infection (Helicobacter pylori) and duodenal ulcer disease.
• is indicated for the long-term treatment of pathological hypersecretory conditions, including Zollinger-Ellison Syndrome.

Important Safety Information about Esomeprazole Strontium Delayed-Release Capsules 49.3 mg:

• Esomeprazole strontium is contraindicated in patients with known hypersensitivity to proton pump inhibitors.  For information about contraindications of antibacterial agents (clarithromycin and amoxicillin) indicated in combination with esomeprazole strontium, refer to the contraindications section of their package inserts.
• Symptomatic response to therapy does not rule out the presence of gastric malignancy. Consider additional follow-up and diagnostic testing in adult patients who have a suboptimal response or an early symptomatic relapse after completing treatment with a proton pump inhibitor (PPI). In older patients, also consider an endoscopy.
• Acute interstitial nephritis has been observed in patients taking PPIs. Discontinue esomeprazole strontium if acute interstitial nephritis develop.
• PPI therapy may be associated with increased risk of Clostridium difficile-associated diarrhea. This diagnosis should be considered for diarrhea that does not improve.
• PPI therapy may be associated with an increased risk of osteoporosis-related fractures of the hip, wrist, or spine. The risk of fracture was increased in patients who received high-dose (multiple daily doses) and long-term (a year or longer) therapy.
• Cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE) have been reported in patients taking PPIs, including esomeprazole. These events included both new onset and exacerbations. If signs or symptoms consistent with CLE or SLE are noted with esomeprazole strontium, discontinue and refer the patient to a specialist. Most patients improve with discontinuation of the PPI alone in 4 to 12 weeks.
• Avoid concomitant use of esomeprazole strontium with clopidogrel, due to a reduction in plasma concentrations of the active metabolite of clopidogrel. When using esomeprazole strontium consider alternative anti-platelet therapy.
• Daily treatment with any acid-suppressing medications over a long period of time (e.g., longer than 3 years) may lead to malabsorption of cyanocobalamin (vitamin B12). Rare reports of cyanocobalamin deficiency occurring with acid-suppressing therapy have been reported in the literature.
• Hypomagnesemia has been reported rarely with prolonged treatment with PPI therapy and may require discontinuing PPI therapy.
• Concomitant use of esomeprazole strontium and St. John’s wort or rifampin can substantially decrease esomeprazole strontium concentrations. Avoid concomitant use.
• Literature suggests that concomitant use of PPIs with methotrexate (primarily at high dose; see methotrexate prescribing information) may elevate and prolong serum levels of methotrexate and/or its metabolite, possibly leading to methotrexate toxicities. In high-dose methotrexate administration, a temporary withdrawal of the PPI may be considered in some patients.
• Concomitant use of esomeprazole strontium and atazanavir or nelfinavir is not recommended. esomeprazole strontium is expected to increase the plasma levels of saquinavir. Consider dose reduction of saquinavir.
• Patients treated with PPIs and warfarin concomitantly may need to be monitored for increases in INR and prothrombin time. Esomeprazole may interfere with the absorption of drugs for which gastric pH affects bioavailability (e.g., ketoconazole, iron salts, erlotinib, digoxin and mycophenolate mofetil).
• Esomeprazole strontium may increase systemic exposure of cilostazol and one of its active metabolites. Consider dose reduction of cilastozol.
• In adults, adverse reactions (ARs) reported at a frequency of 1% or greater with esomeprazole strontium include headache, diarrhea, nausea, flatulence, abdominal pain, constipation, and dry mouth.
• Safety and effectiveness of esomeprazole strontium have not been established in pediatric patients. Not recommended for use in pediatric patients.
• Safety of esomeprazole strontium have not been studied in patients with severe renal impairment. Not recommended for use in patients with severe renal impairment.
