TenNor Therapeutics Reports Landmark Success in New Trial

TenNor Therapeutics Unveils Encouraging Trial Results

TenNor Therapeutics, a prominent clinical-stage company, recently announced groundbreaking results from its Phase III clinical trial of rifasutenizol (TNP-2198) aimed at treating Helicobacter pylori (H. pylori) infections. This trial indicated substantial efficacy advantages of the rifasutenizol regimen over the conventional bismuth-containing quadruple therapy (BQT). The study achieved its primary endpoints, shedding light on the future of H. pylori treatment.

A Comprehensive Study Design

This pivotal study was designed as a multicenter, randomized, double-blind, controlled trial evaluating the safety and effectiveness of rifasutenizol in combination with amoxicillin and rabeprazole for treating confirmed H. pylori infections in treatment-naive patients. Conducted across 40 hospitals, the trial involved 700 patients whose H. pylori infection was verified through positive carbon-13 urea breath tests and histological examinations.

Robust Patient Involvement

Patients were randomly assigned to receive either rifasutenizol triple therapy (comprising rifasutenizol 400 mg, amoxicillin 1 g, and rabeprazole 20 mg) or BQT treatment, administered twice daily for a course of 14 days. The key efficacy measure was determined through results of the carbon-13 urea breath test 4 to 6 weeks post-treatment.

Impressive Efficacy Results

High compliance rates were observed, with a minimal dropout rate of only 3%. Impressively, H. pylori was successfully cultured from 87% of participants. The study found no significant demographic differences or baseline antibiotic resistance variations that could skew results across the treatment groups. Notably, resistance rates to common antibiotics among clinical isolates were concerning, with clarithromycin at 41%, metronidazole at 68%, and others falling in between.

Rifasutenizol Outperforms Standard Treatments

Rifasutenizol's triple therapy achieved a remarkable eradication rate of over 90% in the modified intention-to-treat (mITT) population, outperforming the BQT control group (92% versus 87.9%, a significant difference of 4.1%). In the per protocol (PP) population, rifasutenizol achieved an equally impressive 93.7% eradication rate compared to BQT at 90.3%.

Enhanced Safety Profile

Safety and tolerability assessments showed that rifasutenizol exhibited a better profile than BQT, with lower rates of treatment-emergent adverse events (TEAEs). Most adverse events were graded as minor, with no serious adverse events reported linked to the investigational drug. This places rifasutenizol in an advantageous position for minimizing patient risk while promoting effective treatment.

Potential for Revolutionary Impact

Rifasutenizol represents a novel multi-targeting drug, specifically designed to combat anaerobic and microaerophilic bacterial infections. It could usher in a new era in H. pylori treatment as the first new drug approved in over 30 years. Its unique characteristics allow it to be integrated seamlessly with existing testing methods to combat the high incidence of gastric cancer associated with untreated infections in high-risk populations.

The Future of TenNor Therapeutics

TenNor has successfully completed seven clinical trials, spanning Phase I to III, contributing significantly to understanding and developing new treatment regimes for infectious diseases. The company has achieved notable regulatory designations from the U.S. FDA, including Qualified Infectious Disease Product (QIDP) and Fast Track designations.
