Craig Miller, RedHill’s VP U.S. Business Operations, Market Access, said: “RedHill’s U.S. commercial operations, headquartered in Raleigh, NC, include a gastrointestinal (GI)-focused sales force of 40 sales representatives promoting Donnatal®2 and EnteraGa®3 in select U.S. territories. We are excited to promote a third GI specialty commercial product and to offer patients an additional therapeutic option. Esomeprazole Strontium DR Capsules 49.3 mg complements RedHill’s rapidly growing U.S. GI specialty commercial product portfolio. RedHill is pursuing additional commercial opportunities in the specialty GI area to further expand its commercial presence in the U.S. We thank our new partner ParaPRO for their trust and cooperation, and are looking forward to a fruitful partnership.”

Patrick O’Shea, ParaPRO’s VP of Marketing, added: “Our partnership with RedHill will generate a synergistic effort to commercialize the benefits of Esomeprazole Strontium DR Capsules 49.3 mg, and address the unmet need for therapeutic consistency we believe is sought by both healthcare practitioners and patients.”

The initial term of the commercialization agreement is for three years. RedHill expects to initiate the U.S. promotion of the product in the coming weeks.

Under the terms of the agreement, RedHill and Concordia will share the revenues generated from the promotion of Donnatal® by RedHill, based on an agreed upon split.

About Donnatal®
Donnatal® (Phenobarbital, Hyoscyamine Sulfate, Atropine Sulfate, Scopolamine Hydrobromide), a prescription drug, is classified as possibly effective as an adjunctive therapy in the treatment of irritable bowel syndrome (irritable colon, spastic colon, mucous colitis) and acute enterocolitis. Donnatal® slows the natural movements of the gut by relaxing the muscles in the stomach and intestines. Donnatal® comes in two formulations: immediate release Donnatal® Tablets and immediate release Donnatal® Elixir, a fast-acting liquid.

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 components5, 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 disorders6.
