Talicia is the leading branded first-line therapy prescribed by U.S. gastroenterologists[2] for H. pylori infection, which affects approximately 35% of the U.S. adult population[3]
Worldwide, around 66% of the population has H. pylori infection[4], which is classified by the World Health Organization (WHO) as a Group 1 carcinogen, being the strongest known risk factor for gastric cancer[5] and a major risk factor for peptic ulcer disease[6]
RALEIGH, N.C. and TEL-AVIV, Israel, Sept. 9, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced the placement of low-dose rifabutin-triple therapy, Talicia, as an empirically-prescribed first-line option for the treatment of Helicobacter pylori (H. pylori) infection in the newly published American College of Gastroenterology (ACG) Clinical Guideline: Treatment of H. pylori Infection, previously updated in 2017.
"The ACG Clinical Guideline is clear that clarithromycin-based triple therapy is no longer a reliable first-line option for the treatment of H. pylori infection, unless prior resistance testing has shown clarithromycin susceptibility. Resistance rates to both of the antibiotics contained in Talicia, amoxicillin and rifabutin, are minimal - <3.0% and <1.0%, respectively[7] - supporting Talicia as a rational empirically-prescribed first-line option," Dr. Colin W. Howden, MD, Professor Emeritus, Chief of the Division of Gastroenterology, University of Tennessee Health Science Center. "Talicia's all-in-one formulation and flexible dosing schedule – three times daily (TID), at least four hours apart with food, for 14 days – offers a simplified patient experience, supporting high rates of eradication without the requirement of prior resistance testing."
It has been almost eight years since the ACG Clinical Guideline's last update, which was prior to the launch of Talicia. "The newly updated ACG Clinical Guideline confirms the use of Talicia as a first-line option," said Rick D. Scruggs, President and Chief Commercial Officer of RedHill Biopharma, Inc. "Healthcare providers can be confident in their choice of Talicia without the requirement of prior resistance testing, and we trust that this newly updated ACG Clinical Guideline will continue to change the status quo of H. pylori treatment to further improve patient outcomes."
About H. pylori H. pylori is a bacterial infection that affects approximately 35%[8] of the U.S. population, with an estimated two million patients treated annually3. Worldwide, around 66% of the population has H. pylori infection, which is classified by the World Health Organization (WHO) as a Group 1 carcinogen. It remains the strongest known risk factor for gastric cancer[9] and a major risk factor for peptic ulcer disease[10] and gastric mucosa-associated lymphoid tissue (MALT) lymphoma[11]. More than 27,000 Americans are diagnosed with gastric cancer annually[12]. Eradication of H. pylori is becoming increasingly difficult, with current therapies failing in approximately 25-40% of patients who remain H. pylori-positive due to high resistance of H. pylori to antibiotics – especially clarithromycin – which is still commonly used in standard combination therapies[13].
About Talicia® Talicia® is the only low-dose rifabutin-based therapy approved for the treatment of H. pylori infection and is designed to address the high resistance of H. pylori bacteria seen with 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 WHO in recent years.
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). In November 2019, Talicia® was approved by the U.S. FDA for the treatment of H. pylori infection in adults. In the pivotal Phase 3 study, Talicia® demonstrated 84% eradication of H. pylori infection in the intent-to-treat (ITT) group vs. 58% in the active comparator arm (p<0.0001). Minimal to zero resistance to rifabutin, a key component of Talicia®, was detected in RedHill's pivotal Phase 3 study. Further, in an analysis of data from this study, it was observed that subjects who were confirmed adherent[14] to their therapy had response rates of 90.3% in the Talicia® arm vs. 64.7% in the active comparator arm[15]. 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.
TALICIA: INDICATION AND IMPORTANT SAFETY INFORMATION
Talicia is a three-drug combination of omeprazole, a proton pump inhibitor, amoxicillin, a penicillin-class antibacterial, and rifabutin, a rifamycin antibacterial, indicated for the treatment of Helicobacter pylori infection in adults. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Talicia and other antibacterial drugs, Talicia should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.
IMPORTANT SAFETY INFORMATION
Talicia contains omeprazole, a proton pump inhibitor (PPI), amoxicillin, a penicillin-class antibacterial and rifabutin, a rifamycin antibacterial. It is contraindicated in patients with known hypersensitivity to any of these medications, any other components of the formulation, any other beta-lactams or any other rifamycin.
Talicia is contraindicated in patients receiving rilpivirine-containing products.
Talicia is contraindicated in patients receiving delavirdine or voriconazole.
Serious and occasionally fatal hypersensitivity reactions have been reported with omeprazole, amoxicillin and rifabutin.
Drug-induced enterocolitis syndrome (DIES) has been reported with use of amoxicillin, a component of Talicia.
Severe cutaneous adverse reactions (SCAR) (e.g., Stevens-Johnson syndrome (SJS), Toxic epidermal necrolysis (TEN)) have been reported with rifabutin, amoxicillin, and omeprazole. Additionally, drug reaction with eosinophilia and systemic symptoms (DRESS) has been reported with rifabutin.
Acute Tubulointerstitial Nephritis has been observed in patients taking PPIs and penicillins.
Clostridioides difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents and may range from mild diarrhea to fatal colitis.Talicia may cause fetal harm. Talicia is not recommended for use in pregnancy. Talicia may reduce the efficacy of hormonal contraceptives. An additional non-hormonal method of contraception is recommended when taking Talicia.
Talicia should not be used in patients with hepatic impairment or severe renal impairment.
Cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE) have been reported in patients taking PPIs. These events have occurred as both new onset and exacerbation of existing autoimmune disease.
The most common adverse reactions (=1%) were diarrhea, headache, nausea, abdominal pain, chromaturia, rash, dyspepsia, oropharyngeal pain, vomiting, and vulvovaginal candidiasis.
