RedHill Biopharma Presents Three New Analyses of Movantik Data at PAINWeek 2021
Two new analyses of Movantik® (naloxegol) data evaluated the safety and efficacy of Movantik in a subgroup of patients aged ≥ 65 years
Analysis of Movantik effects on rapid and sustained improvement of both spontaneous and complete spontaneous bowel movements in the Movantik group vs. placebo were evaluated across high and low opioid dosages
Movantik is the U.S. market-leading oral peripherally acting mu-opioid receptor antagonist (PAMORA), approved to treat opioid-induced constipation in adults with chronic non-cancer pain
TEL AVIV, ISRAEL and RALEIGH, NC / ACCESSWIRE / September 7, 2021 / RedHill Biopharma Ltd. (NASDAQ:RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced presentation at PAINWeek 2021 of three new analyses of Movantik® (naloxegol) Phase 3 study data demonstrating rapid onset of action and sustained and predictable improvement of key symptoms associated with opioid-induced constipation (OIC) in both a subgroup of patients aged ≥ 65 and across both low and high dose opioid therapy.
Two of the posters are dedicated to the subgroup of patients aged ≥ 65, with Movantik achieving significantly better response rates vs. placebo, with rapid onset of action and a higher proportion of subjects achieving spontaneous bowel movement (SBM) and complete spontaneous bowel movement (CSBM) over the first 48 hours of treatment. Additional presented data also shows that naloxegol delivers similar rapid and sustained symptom improvement for patients, irrespective of the opioid dose they are prescribed, including at doses lower than 100 mg of morphine equivalent. The authors conclude that even with lower doses of morphine equivalent, clinicians should be diligent about treating these patients because they still are susceptible to OIC.
The three analyses included pooled data from two large, robust, identically designed Phase 3 studies of Movantik (Kodiak 4 and Kodiak 5; NCT01309841/NCT01323790), involving 891 treated patients across two doses (12.5 mg and 25 mg), compared to a total of 446 patients in the placebo arms.
"With up to 90% of older patients receiving opioids to help cope with chronic pain, and up to 86% of them suffering from symptoms of OIC, these new analyses are particularly important in helping these patients achieve satisfactory control of their pain without the added burden of OIC. Older patients tend to be more susceptible to OIC due to comorbidities, polypharmacy, and reduced physical activity, and it is vital that they have access to therapies such as Movantik, that are shown to be effective in this challenging patient group." said Dr. Lynn Webster, Pain Researcher and Clinician and Senior Fellow at the Center of U.S. Policy.
"There has been a shift in clinical practice to try to reduce doses of opioids used to treat chronic pain. However, low dose opioid therapy can prove to be equally troublesome in terms of treatment-related constipation as higher doses and it is important that physicians are diligent in monitoring for signs of OIC," said Dr. June Almenoff, MD, Ph.D., RedHill's Chief Scientific Officer. "This new analysis showing Movantik's efficacy irrespective of opioid dose is equally important in supporting the clinical shift to low dose opioid therapy through the management of OIC which can be expected in between 40-80% of patients taking chronic opioid therapy."

About Movantik® (naloxegol)
Movantik® is an opioid antagonist indicated for the treatment of opioidinduced constipation (OIC) in adult patients with chronic non-cancer pain, including patients with chronic pain related to prior cancer or its treatment who do not require frequent (e.g., weekly) opioid dosage escalation.
Important Safety Information About Movantik
Movantik® (naloxegol) is contraindicated in:
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 (e.g., 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 patients (e.g., 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.
Severe abdominal pain and/or diarrhea have been reported, generally within a few days of initiation of Movantik. Monitor and discontinue if severe symptoms occur. Consider restarting Movantik at 12.5 mg once daily.
Cases of GI perforation have been reported with the use of peripherally acting opioid antagonists, including Movantik. Postmarketing cases of GI perforation, including fatal cases, were reported when Movantik was used in patients at risk of GI perforation (e.g., 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.
The most common adverse reactions with Movantik as compared to placebo in clinical trials were: Abdominal pain (21% vs 7%), diarrhea (9% vs 5%), nausea (8% vs 5%), flatulence (6% vs 3%), vomiting (5% vs 4%), headache (4% vs 3%), and hyperhidrosis (3% vs <1%).
Movantik (naloxegol) is indicated for the treatment of opioid-induced constipation (OIC) in adult patients with chronic non-cancer pain, including patients with chronic pain related to prior cancer or its treatment who do not require frequent (e.g., weekly) opioid dosage escalation.
