As per the agreement terms, RedHill will be responsible for certain promotional activities related to the drug, while Concordia will take responsbility for its manufacturing and supply in all territories.

RedHill CEO Dror Ben-Asher said: “With a core US commercial team in place, we plan to initiate promotional activities in the US in the coming months with a specialty gastrointestinal sales force.

“RedHill’s strategic transition into a revenue-generating, gastrointestinal-focused, specialty pharmaceutical company with commercial presence in the US, is planned to support potential future commercialisation of our Phase III-stage potential blockbusters Bekinda for gastroenteritis and other GI indications, RHB-105 for H. pylori infection and RHB-104 for Crohn’s disease, if approved by FDA.”

"This agreement is a cost-effective approach to promoting Donnatal in a manner consistent with our long-term strategic focus on operational excellence."

Based on an agreed upon split, RedHill and Concordia will share the revenues generated from the promotion of the drug.

The agreement with Concordia is initially for a period of three years.

Concordia CEO Allan Oberman said: “This agreement is a cost-effective approach to promoting Donnatal in a manner consistent with our long-term strategic focus on operational excellence.

“We look forward to partnering with them to market Donnatal to more key prescribers who we believe can help raise the product’s profile and potentially allow us to reach more patients in the US.”

Donnatal relaxes the muscles in the stomach and intestines and acts on the brain to produce a calming effect and slows the natural movements of the gut.

It is available in two formulations: immediate release Donnatal Tablets, and immediate release Donnatal Elixir, a fast acting liquid.
