RedHill Biopharma Presents a New Travelers' Diarrhea Clinical Severity Classification Tool and its Use in Aemcolo Efficacy Analysis at DDW 2021
RedHill Biopharma (Nasdaq: RDHL) presented a new Travelers' Diarrhea (TD) severity classification tool at Digestive Disease Week 2021, developed with the University of Texas School of Public Health. This tool aims to enhance clinical practice by providing clear separation of TD severity categories. The efficacy of Aemcolo (rifamycin) was confirmed through this tool, showing high effectiveness in moderate to severe TD cases. Aemcolo is noteworthy for its non-systemic delivery, resulting in limited side effects. This advancement could boost demand as travel resumes post-COVID.
- Confirmation of Aemcolo's high efficacy in treating moderate to severe TD.
- Development of a new clinical tool for better disease prognosis, enhancing Aemcolo's clinical utility.
- Increased demand potential for Aemcolo as travel resumes, addressing TD risks.
- Aemcolo is only effective against non-invasive strains of E. coli, limiting its market scope.
TEL AVIV, Israel and RALEIGH, N.C., May 21, 2021 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced presentation (poster number: Fr244) at Digestive Disease Week 2021 of a new Travelers' Diarrhea (TD) severity classification tool providing clear separation of clinical severity categories and prognostic information for TD resolution, with potential utility in clinical practice. The new tool was developed with the Center for Infectious Diseases, University of Texas Houston School of Public Health.
The new classification tool was used to assess the efficacy of Aemcolo® (rifamycin) for the treatment of TD caused by non-invasive strains of E. coli in adults[1], reconfirming high levels of efficacy across both moderate and severe patient groups.
"Antibiotics are the mainstay of treating bacterial TD; due to growing resistance, they should be reserved for use in more severe cases of the disease," said Professor Herbert L. DuPont, Director of the Center for Infectious Diseases, University of Texas Houston School of Public Health. "In order to help direct treatment to the most appropriate patients, we developed a new severity classification tool able to support accurate prognosis of disease course and resolution, based on extensive patient data from two Phase 3 trials in Travelers' Diarrhea, providing significant potential clinical utility. We then used the new classifications to assess the efficacy of rifamycin, reconfirming highly statistically significant efficacy across both newly reclassified moderate and severe patient groups."
"Outcomes-focused clinical tools to assess the prognosis in TD have been lacking, and the development of this new Travelers' Diarrhea severity classification tool provides prognostic information that may help guide clinical practice," said June Almenoff, M.D., Ph.D., FACP, RedHill's Chief Medical Officer. "As the world returns to normal post-COVID pandemic, many Americans will likely want to resume travelling to countries where they are at high risk of infection with TD and will want to avoid the risk of ruining their trip by planning ahead for potential cases of TD."
Aemcolo, containing 194 mg of rifamycin as delayed-release tablets, is an orally-administered, non-systemic antibiotic employing MMX® technology, a proprietary drug delivery system that distributes rifamycin in a controlled manner to the lower intestine. Due to its non-systemic delivery, Aemcolo is associated with limited side effects and minimal potential for interactions with other medications.
Aemcolo is listed as an acute diarrhea antibiotic treatment recommendation in the Centers for Disease Control and Prevention (CDC) Yellow Book[2]. The recommended dosage of Aemcolo is 388 mg (two tablets) orally, twice daily for three days.
About Traveler's Diarrhea
Travelers' Diarrhea (TD) is the most common travel-related illness, affecting an estimated
About Aemcolo® (rifamycin)
Aemcolo® (rifamycin) is an orally-administered, delayed-release, non-systemic antibiotic approved for the treatment of travelers' diarrhea caused by non-invasive strains of Escherichia coli (E. coli) in adults. Aemcolo® is the first antibiotic engineered with Cosmo Pharmaceuticals' Multi Matrix Technology (MMX®). MMX technology is designed to deliver the active pharmaceutical ingredients in a delayed and controlled manner directly to the lower intestine.
INDICATION AND IMPORTANT SAFETY INFORMATION
Aemcolo® is indicated for the treatment of travelers' diarrhea caused by noninvasive strains of Escherichia coli (E. coli) in adults.
Limitations of Use
Aemcolo® is not indicated in patients with diarrhea complicated by fever or bloody stool or due to pathogens other than noninvasive strains of E. coli.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Aemcolo® and other antibacterial drugs, Aemcolo® should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.
CONTRAINDICATION
Aemcolo® is contraindicated in patients with a known hypersensitivity to rifamycin, any of the other rifamycin class antimicrobial agents, or any of the components in Aemcolo®.
WARNINGS AND PRECAUTIONS
Risk of Persistent or Worsening Diarrhea Complicated by Fever and/or Bloody Stool
Aemcolo® was not shown to be effective in patients with diarrhea complicated by fever and/or bloody stool or diarrhea caused by pathogens other than E. coli and is not recommended for use in such patients.
Discontinue Aemcolo® if diarrhea gets worse or persists more than 48 hours and consider alternative antibacterial therapy.
Clostridium difficile-Associated Diarrhea (CDAD)
CDAD has been reported with use of nearly all antibacterial agents and may range in severity from mild diarrhea to fatal colitis.
Consider CDAD in all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
Development of Drug-Resistant Bacteria
Prescribing Aemcolo® in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
ADVERSE REACTIONS
Discontinuation of Aemcolo® due to adverse reactions occurred in
Adverse reactions that occurred in at least
USE IN SPECIFIC POPULATIONS
