RedHill Presents New Talicia® and Movantik® Data Analyses at ACG 2022
RedHill Biopharma (Nasdaq: RDHL) presented new data analyses for its products Talicia and Movantik at the ACG Annual Meeting on October 21-26, 2022. A PBPK modeling study revealed that Talicia, a leading H. pylori treatment, provides superior intragastric antibiotic exposure with a dosing regimen of 50 mg rifabutin every 8 hours compared to standard rifabutin therapies. Movantik, the top oral PAMORA for opioid-induced constipation, demonstrated significant improvements in patient quality of life and symptom control in pooled analyses of phase 3 studies. RedHill emphasizes Talicia's efficacy in addressing antibiotic resistance issues.
- Talicia showed favorable intragastric rifabutin concentrations, enhancing H. pylori eradication rates (84-90%) compared to generic regimens (70%).
- Movantik demonstrated clinically meaningful improvements in quality of life and symptoms in opioid-induced constipation patients (40-70% more likely vs. placebo).
- Talicia is the only low-dose rifabutin-based therapy addressing high antibiotic resistance, with eight years of U.S. market exclusivity and patent protection until 2034.
- None.
Physiologically-Based Pharmacokinetic (PBPK) modeling study of Talicia evaluated intragastric antibiotic exposure, critical for successful H. pylori eradication, comparing low-dose rifabutin 50 mg every 8 hours to generic rifabutin triple therapy 150mg twice a day or 300 mg once a day.
Talicia, the leading prescribed branded H. pylori therapy by U.S. gastroenterologists, is intended for empiric first-line eradication of H. pylori, a bacterial infection that affects approximately
Pooled analyses of Movantik phase 3 studies in opioid-induced constipation assess impact on patient quality of life and symptom improvement
Movantik is the most prescribed oral PAMORA prescribed by U.S. pain specialists for opioid-induced constipation with over 3.2 million prescriptions written since 2015
RALEIGH, N.C. and TEL-AVIV, Israel, Oct. 26, 2022 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, announced the presentation of new data analyses for Talicia®, for the treatment of H. pylori, and Movantik®, for the treatment of opioid -induced constipation (OIC), at the American College of Gastroenterology Annual Meeting (ACG) October 21-26, 2022.
Sufficient intragastric antibiotic exposure is critical for eradication of H. pylori, consequently, understanding the influence of antibiotic dosing on intragastric exposure is imperative. This study used Physiologically-Based Pharmacokinetic (PBPK) modeling to compare intragastric rifabutin concentrations with Talicia (low-dose rifabutin 50 mg) administered every 8 hours (Q8H) vs. rifabutin 150 mg (the generically available dose) administered twice daily (BID) or 300 mg administered once daily (QD). This analysis indicates that Talicia provides favorable intragastric rifabutin concentration and as a result provides high potential for H. pylori eradication while minimizing systemic antibiotic exposure.
Poster title (poster number: A0683): Modeling Gastric Luminal Rifabutin Concentrations: RHB-105 (Rifabutin 50mg Q8H) Provides More Favorable Exposure for H. pylori Eradication Than Generic Rifabutin 150mg BID or 300mg QD
Presenting Author: Dr. Colin W. Howden, MD, Professor Emeritus, Chief of the Division of Gastroenterology, University of Tennessee Health Science Center.
This analysis builds upon previous work and demonstrates that two generically available rifabutin regimens (150 mg BID and 300 mg QD) did not maintain the intragastric rifabutin concentrations seen with Talicia, despite containing twice the total daily dose of rifabutin. This may help to explain the lower eradication rates seen with generic rifabutin triple therapy regimens (about
"These important new data enhance the body of evidence supporting the use of Talicia as a first line therapy for H. pylori," said Dr. June Almenoff, MD, Ph.D., RedHill's Chief Medical Officer. "This work demonstrates sustained intragastric exposure providing optimized conditions for eradication of H. pylori. Given the need to aim for the most effective empiric first-line eradication therapy, it is important to utilize a therapy with the highest likelihood of eradication success, such as Talicia."
The two Movantik posters are pooled analyses (n= 1337) of two phase 3 clinical studies (KODIAC-04 and -05) of Movantik in patients with OIC and assess the impact of Movantik on patient quality of life according to the validated patient assessment of constipation, quality of life questionnaire (PAC-QOL), and symptom improvement according to the patient assessment of constipation, symptoms questionnaire (PAC-SYM):

Presenting Author: Dr. Darren M. Brenner, MD, Professor of Medicine and Surgery (Gastroenterology and Hepatology), Northwestern University, Feinberg School of Medicine.
This poster evaluated the efficacy of naloxegol in providing clinically meaningful HR-QOL improvement in patients with OIC. Data showed that Movantik demonstrated rapid and clinically meaningful constipation related quality of life improvement in the overall population (40

This second Movantik poster evaluated the efficacy of Movantik in providing clinically meaningful symptom improvement, based on the PAC-SYM patient reported outcome, in patients with OIC. Data showed that Movantik demonstrated rapid and clinically meaningful constipation related symptom improvement in the overall population (20
In both analyses Movantik was well tolerated and demonstrated a favorable safety profile.
About H. pylori infection H. pylori is a bacterial infection that affects approximately
About Talicia Talicia is a novel, fixed-dose, all-in-one oral capsule combination of two antibiotics (amoxicillin and rifabutin) and a proton pump inhibitor (PPI) (omeprazole), approved by the U.S. FDA for the treatment of H. pylori infection in adults.
Talicia is the only low-dose rifabutin-based therapy approved for the treatment of H. pylori infection and is designed to address H. pylori's high resistance to other antibiotics. The high rates of H. pylori resistance to clarithromycin have led to significant rates of treatment failure with clarithromycin-based therapies and are a strong public health concern, as highlighted by the ACG, FDA and the World Health Organization (WHO) in recent years.
In the pivotal Phase 3 study, Talicia demonstrated
Talicia is eligible for a total of eight years of U.S. market exclusivity under its Qualified Infectious Disease Product (QIDP) designation and is also covered by U.S. patents which extend patent protection until 2034 with additional patents and applications pending and granted in various territories worldwide.
