RedHill Biopharma Presents a New Travelers' Diarrhea Clinical Severity Classification Tool and its Use in Aemcolo Efficacy Analysis at DDW 2021
- New Travelers' Diarrhea (TD) severity classification tool, developed with the University of Texas Houston School of Public Health, provides clear separation of clinical severity categories and prognostic information for TD resolution with potential utility in clinical practice
- The data presented include a new efficacy assessment of Aemcolo® (rifamycin) for the treatment of TD, demonstrating high levels of efficacy across both moderate and severe patient groups
- Aemcolo (rifamycin) is a non-systemic antibiotic whose delivery is targeted to the site of non-invasive Escherichia Coli (E. coli) infection in the distal small bowel and colon, approved by the FDA for the treatment of TD
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, 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
"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
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
About Traveler's Diarrhea
Travelers' Diarrhea (TD) is the most common travel-related illness, affecting an estimated 10% to 40% of travelers annually[iii]. Each year, approximately 70 million Americans travel abroad[iv]. Attack rates of TD range up to 70% of travelers, depending on the destination and season of travel[v]. TD may often result in short-term morbidity adversely impacting travel plans. Untreated diarrhea can also lead to an underappreciated risk of chronic complications, including functional bowel disorders[vi].
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.
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.
Discontinuation of Aemcolo® due to adverse reactions occurred in 1% of patients. The most frequent adverse reactions were abdominal pain (0.5%) and pyrexia (0.3%).
Adverse reactions that occurred in at least 2% of Aemcolo®-treated patients and with a higher incidence than in the placebo or ciprofloxacin groups were constipation 3.5% and headache 3.3%, respectively.
USE IN SPECIFIC POPULATIONS
There are no available data on AEMCOLO use in pregnant women to inform any drug-associated risks for major birth defects, miscarriage, or adverse maternal or fetal outcomes.
There is no information regarding the presence of AEMCOLO in human milk, the effects on the breastfed infant, or the effects on milk production.
The safety and effectiveness of AEMCOLO has not been established in pediatric patients <18 years of age.
