TEL AVIV, Israel and RALEIGH, N.C., Feb. 18, 2021 /PRNewswire/ -- RedHill Biopharma Ltd. (NASDAQ:RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced agreements with Cosmo Pharmaceuticals NV (SIX: COPN) ("Cosmo") to manufacture two key products; RedHill's largest selling product in the U.S., Movantik^®, and RHB-204, currently in a Phase 3 U.S. study as a stand-alone, first-line orally-administered treatment for pulmonary nontuberculous mycobacteria (NTM) disease.

Movantik is the leading prescribed oral peripherally acting mu-opioid receptor antagonist (PAMORA) in the U.S. specifically designed to treat opioid-induced constipation (OIC) in adult patients with chronic non-cancer pain[1]. OIC is the most common and debilitating gastrointestinal adverse effect associated with opioid therapy, estimated to affect between 40-80% of the millions of patients taking chronic opioid therapy each year[2].

RHB-204 is an investigational proprietary, fixed-dose oral capsule containing a combination of clarithromycin, rifabutin, and clofazimine, developed as a stand-alone first-line treatment for pulmonary NTM disease caused by Mycobacterium avium Complex (MAC). Although rare, the incidence and prevalence of pulmonary NTM disease are increasing in many areas of the world[3]. There were an estimated 110,000 pulmonary NTM disease patients in the U.S. in 2017, with U.S. market potential estimated at over $500 million[4]. RHB-204 has received FDA Fast Track, Orphan Drug and QIDP designations aimed at accelerating development and FDA review and extending U.S. market exclusivity to a potential total of 12 years, to be granted at the time of FDA approval.

RedHill Biopharma Ltd. (Nasdaq: RDHL) is a specialty biopharmaceutical company primarily focused on gastrointestinal and infectious diseases. RedHill promotes the gastrointestinal drugs, Movantik^® for opioid-induced constipation in adults^[5], Talicia^® for the treatment of Helicobacter pylori (H. pylori) infection in adults^[6], and Aemcolo^® for the treatment of travelers' diarrhea in adults^[7]. RedHill's key clinical late-stage development programs include: (i) RHB-204, with an ongoing Phase 3 study for pulmonary nontuberculous mycobacteria (NTM) disease; (ii) opaganib (Yeliva^®), a first-in-class SK2 selective inhibitor targeting multiple indications with a Phase 2/3 program for COVID-19 and Phase 2 studies for prostate cancer and cholangiocarcinoma ongoing; (iii) RHB-107 (upamostat), a serine protease inhibitor in a U.S. Phase 2/3 study for symptomatic COVID-19, and targeting multiple other cancer and inflammatory gastrointestinal diseases; (iv) RHB-104, with positive results from a first Phase 3 study for Crohn's disease; (v) RHB-102 (Bekinda^®), with positive results from a Phase 3 study for acute gastroenteritis and gastritis and positive results from a Phase 2 study for IBS-D; and (vi) RHB-106, an encapsulated bowel preparation.

• Patients with known or suspected gastrointestinal (GI) obstruction and patients at risk of recurrent obstruction, due to the potential for GI perforation.
• Patients receiving strong CYP3A4 inhibitors (eg, clarithromycin, ketoconazole) because these medications can significantly increase exposure to naloxegol which may precipitate opioid withdrawal symptoms.
• Patients with a known serious or severe hypersensitivity reaction to Movantik or any of its excipients.

Symptoms consistent with opioid withdrawal, including hyperhidrosis, chills, diarrhea, abdominal pain, anxiety, irritability, and yawning, occurred in patients treated with Movantik. Patients receiving methadone as therapy for their pain condition were observed in the clinical trials to have a higher frequency of GI adverse reactions that may have been related to opioid withdrawal than patients receiving other opioids. Patients with disruptions to the blood-brain barrier may be at increased risk for opioid withdrawal or reduced analgesia. These patient (eg, multiple sclerosis, recent brain injury, Alzheimer's disease, and uncontrolled epilepsy) were not enrolled in the clinical studies. Take into account the overall risk-benefit profile when using Movantik in such patients. Monitor for symptoms of opioid withdrawal when using Movantik in such patients.

Cases of GI perforation have been reported with the use of peripherally acting opioid antagonists, including Movantik. Post marketing cases of GI perforation, including fatal cases, were reported when Movantik was used in patients at risk of GI perforation (eg, infiltrative gastrointestinal tract malignancy, recent gastrointestinal tract surgery, diverticular disease including diverticulitis, ischemic colitis, or concomitantly treated with bevacizumab). Monitor for severe, persistent, or worsening abdominal pain; discontinue if this symptom develops.
