rifasutenizol (TNP-2198) / TenNor Therap - LARVOL DELTA

Mechanism-matched Helicobacter pylori treatment in the potassium-competitive acid blocker era. (PubMed, Front Med (Lausanne)) - "Eradication therapy has become less reliable as resistance to clarithromycin, metronidazole, and levofloxacin has reduced the performance of older empiric regimens...Vonoprazan-based regimens improve acid suppression and can outperform proton pump inhibitor-based triple therapy in clarithromycin-resistant infection, but rescue-treatment trials show that potent acid suppression alone is insufficient when the partner antibiotic is poorly matched...Rifasutenizol adds a pathogen-targeted option supported by phase 3 evidence in treatment-naive Chinese patients. Adjunctive and investigational approaches, including probiotics, vaccines, phytochemicals, phage-derived agents, and nanomedicine, should be interpreted as supportive or developmental strategies rather than replacements for validated antimicrobial regimens. A mechanism-matched approach can help clinicians and investigators choose regimens, interpret trial results, and design studies that distinguish failures caused by..."

Some Newer Antibiotics Active Against Helicobacter pylori and Anaerobic Bacteria and the Potential Benefits of Their Wider Availability in More Countries: A Narrative Review. (PubMed, Antibiotics (Basel)) - "Given the limited number of antibiotics for treating CDI and fidaxomicin nonavailability in many countries, it is necessary to conduct more extensive laboratory and clinical studies of promising antibiotics such as ibezapolstat, delafloxacin, lascufloxacin, omadacycline, eravacycline, ridinilazole, and CRS3123...Research on rifasutenizol for bacterial vaginosis, sarecycline and nadifloxacin for acne vulgaris and amixicile for periodontal diseases needs to be expanded. For H. pylori infection, delafloxacin, sitafloxacin, nemonoxacin, zoliflodacin, and rifasutenizol may improve the suboptimal success of most eradication regimens...Establishing more research groups, careful examination of market issues, and additional approaches, such as nanomaterials, efflux pump inhibitors, phage therapy, and CRISPR-Cas systems, should be beneficial. Notwithstanding the difficulties, there are many opportunities to promote research on and potential use of newer antibiotics which show..."

Rifasutenizol-Based Triple Therapy for the Eradication of Helicobacter pylori. (PubMed, Korean J Helicobacter Up Gastrointest Res) - No abstract available

Journal • Infectious Disease

Therapeutic advances and future directions in Helicobacter pylori eradication. (PubMed, Front Microbiol) - "Although clarithromycin-based triple therapy continues to be effective in certain geographic areas, increasing global resistance highlights the need for treatment approaches tailored to local antibiotic susceptibility patterns. Recent clinical trials have shifted toward optimized quadruple regimens, particularly bismuth- and vonoprazan-based therapies, and resistance-guided treatment. Novel agents such as Rifasutenizol (TNP-2198) are entering phase 3 evaluation and show activity against multidrug-resistant strains...Multi-strain probiotic formulations and plant-derived compounds such as curcumin, catechins, and quercetin consistently suppress H. pylori virulence pathways and gastric inflammation in clinical and preclinical studies. This review provides an overview of current evidence from clinical trials and emerging therapeutic innovations, emphasizing balanced integration of conventional and next-generation approaches for sustainable global H. pylori management."

(PubMed, Lancet Infect Dis) - P1, P1/2, P2 | "Rifasutenizol monotherapy and combination therapy was generally safe and well tolerated in healthy participants and patients with H pylori infection. A triple regimen of 400 mg rifasutenizol capsules, 20 mg rabeprazole sodium enteric-coated tablets, and 1 g amoxicillin capsules twice a day for 14 days showed promising efficacy as a new treatment regimen for H pylori infection."
