Near-term implementable finding

Efficacy and Safety of Vonoprazan-Based Dual Therapies With Different Antibiotics Versus Bismuth-Containing Quadruple Therapy for Helicobacter pylori Eradication: A Prospective, Four-Arm, Randomized Controlled Trial

Two-drug stomach ulcer treatments work as well as older four-drug regimens but cause fewer side effects, offering simpler options.

This 4-arm RCT demonstrates that vonoprazan-amoxicillin (VA) and vonoprazan-minocycline (VM) dual therapies achieve eradication rates comparable to bismuth quadruple therapy (BQT) with fewer adverse events, potentially offering simpler and better-tolerated first-line H. pylori eradication options. Findings are exploratory and warrant confirmation in larger adequately powered trials.

Why it surfaced

Well-designed RCT comparing vonoprazan regimens vs BQT in a clinically significant area. Vonoprazan-based simplification of H. pylori therapy is a near-term implementable advance. Adjacent to watchlist via hematologic implications (H. pylori → ITP, MALT).
