TEL-AVIV, Israel and RALEIGH, N.C., Oct. 18, 2019 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq: RDHL) (Tel-Aviv Stock Exchange: RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company primarily focused on the development and commercialization of clinical late-stage, proprietary drugs for the treatment of gastrointestinal diseases, today announced that it has entered into a strategic collaboration with Cosmo Pharmaceuticals N.V. (SIX:COPN) (“Cosmo”).

The strategic collaboration includes an exclusive license agreement for the U.S. rights to Aemcolo® (rifamycin) and a simultaneous private investment by Cosmo of $36.3 million in RedHill at $7.00 per American Depositary Share (ADS), representing approximately 13.5% over the closing price on October 17, 2019, with a 180-day transfer restriction.

Following this transaction, RedHill will maintain a debt-free balance sheet with approximately $59 million of cash and cash equivalents and will be well-positioned to launch RHB-105 (Talicia®)1 for H. pylori infection in the U.S. with an expanded sales force, if approved by the Food and Drug Administration (FDA). The New Drug Application (NDA) for RHB-105 (Talicia®) is under priority review by the FDA, with an assigned target Prescription Drug User Fee Act (PDUFA) action date of November 2, 2019.

Aemcolo® (rifamycin), containing 194mg of rifamycin as delayed-release tablets, is a minimally absorbed antibiotic that is delivered to the colon, approved by the FDA in 2018 for the treatment of travelers’ diarrhea caused by non-invasive strains of E. coli in adults (“Travelers’ Diarrhea”).

Under the terms of the license agreement, Cosmo granted RedHill the exclusive rights to commercialize Aemcolo® in the U.S. for Traveler’s Diarrhea and agreed to act as the exclusive supplier of Aemcolo®. The license agreement also provides for the grant to RedHill of certain rights related to the potential development of additional indications for Aemcolo®, as well arrangements related to other pipeline product candidates of Cosmo.

As part of the Aemcolo® license agreement, RedHill will issue Cosmo 1,714,286 ADSs at an agreed value of $12 million, as an upfront payment for the rights granted under the license, corresponding to a price per ADS of $7.00, representing approximately 13.5% over the closing price on October 17, 2019, with a 180-day transfer restriction. These ADSs are in addition to the ADSs issued to Cosmo as part of the $36.3 million investment discussed above. In addition, RedHill agreed to pay Cosmo a royalty percentage in the high twenties on net sales generated from the commercialization of Aemcolo® in the U.S. The license agreement further provides for potential regulatory and commercial milestone payments to Cosmo totaling up to $100 million. In connection with the subscription agreement, Cosmo is entitled to nominate for appointment one member to RedHill’s Board of Directors.

“Cosmo is a world leader in optimized therapies for gastrointestinal diseases with a strong track record of success, expertise and commitment to changing the treatment landscape for patients,” said Dror Ben-Asher, RedHill’s CEO. “The strategic partnership with Cosmo is an important validation of RedHill’s commercial capabilities, promising late-stage pipeline and overall strategy to become a leading gastrointestinal-focused company in the U.S. Cosmo’s investment in RedHill ahead of the potential FDA approval and, if approved by the FDA, launch of RHB-105 (Talicia) and the addition of Aemcolo® to our GI product portfolio, positions us well for the future. We are proud to have Cosmo as our partner and look forward to a successful strategic collaboration.”

Mauro Ajani, Chairman of Cosmo, said: “This deal is another big step in the transformation of Cosmo and it is closer to our history and strategy. After the deals with Medtronic, where we partnered AI and Eleview, we have now found the right U.S. partner for Aemcolo®. We are most pleased to become RedHill’s largest shareholder: this stake is strategic and a demonstration of trust. We look forward to contributing towards making RedHill a rousing success.”

Alessandro Della Chà, CEO of Cosmo, said: “After having received several offers, we believe we have found in RedHill the features for a long and successful collaboration: a strong and expert management team with a history of commercial success, a very interesting pipeline, a company size where our contribution could make a substantial difference and the opportunity of an equity for product deal. We are very happy to start this new partnership.”
