Retrospective data, Review, Journal: P-CAB versus PPI in the eradication of Helicobacter pylori: a systematic review and network meta-analysis. (Pubmed Central) - May 16, 2024 In the eradication treatment of Hp, the efficacy and safety of vonoprazan-based regimens are generally better than those of PPI-based regimens. Among them, the V-Tri-2w regimen has the highest eradication rate and may be the preferred choice for Hp eradication.

COMPARISON OF LONG-TERM EFFECTS OF P-CAB AND PPI ON GASTRIC EMPTYING RATE, SERUM GASTRIN, AND SMALL INTESTINAL MICROBIOMES IN RATS (Hall A, Poster Hall - Walter E. Washington Convention Center) - Mar 14, 2024 - Abstract #DDW2024DDW_5061; No significant differences were observed between PPIs and P-CABs in delayed gastric emptying, hypergastrinemia, and small intestinal dysbiosis after prolonged administration. These findings suggest that despite P-CABs exerting a more potent gastric acid inhibitory effect than PPIs, the adverse effects associated with long-term gastric acid inhibition are likely to be similar between the two drug classes.

COMPARISON OF EFFECTS OF TEGOPRAZAN AND REBAMIPIDE COMBINATION THERAPY AND TEGOPRAZAN MONOTHERAPY ON THE HEALING OF ENDOSCOPIC SUBMUCOSAL DISSECTION-INDUCED GASTRIC ULCER: A RANDOMIZED-CONTROLLED, MULTICENTER STUDY (154AB - Walter E. Washington Convention Center) - Mar 14, 2024 - Abstract #DDW2024DDW_4302; A total of 132 lesions and 121 lesions were included in the modified intention-to-treat (mITT) and per-protocol analyses, respectively. The ulcer healing rate at 4 weeks (96.4 % vs. 93.5%, P=0.02 in the mITT analysis) was significantly higher in the combination group than tegoprazan monotherapy group, and combination therapy was a significant predictor for the higher than mean ulcer healing at 4 weeks (OR 2.28, 95% CI 1.04-5.02, P=0.04).

COMPARATIVE EFFICACY OF VONOPRAZAN WITH PROTON PUMP INHIBITORS AND OTHER POTASSIUM-COMPETITIVE ACID BLOCKERS FOR REFLUX ESOPHAGITIS: A NETWORK META-ANALYSIS (ePosters - DDW Online Platform) - Mar 14, 2024 - Abstract #DDW2024DDW_529; Randomized controlled trials of (1) endoscopy-confirmed RE patients ?18 years, (2) receiving at least 2 of these intervention arms: vonoprazan, tegoprazan, kenoprazan, fexuprazan, linaprazan glurate and/or any oral PPIs, (3) reporting at least 1 clinical outcomes of healing rate at 4 weeks for vonoprazan, and 8 weeks for PPIs and other P-CABs and (4) those including >20 patients per group were considered...Specifically, ORs (95% CrI) of PPIs and other P-CABs versus vonoprazan were as follows: fexuprazan 40mg:2.0 (0.056,80.0), keverprazan 20mg:3.6 (0.96,15.0), tegoprazan 50mg:3.4 (0.76,17.0), esomeprazole 20mg:1.7 (0.69,4.1), esomeprazole 40mg:1.8 (0.94,3.4), ilaprazole 10mg:2.1 (0.91,4.8), lansoprazole 30mg:1.4 (0.76,2.4), omeprazole 20mg:1.2 (0.63,2.4), omeprazole 40mg:1.3 (0.53,3.1), pantoprazole 40mg:1.4 (0.70,2.8), and rabeprazole 20mg:1.0 (0.42, 2.3) (Figure 1)...Conclusion This is the first study showing similar efficacy of 4-week vonoprazan course to 8-week PPI course and other P-CABs in healing RE. These results may be helpful to inform clinical practice.

Overall, in terms of nocturnal acid-inhibitory effect, vonoprazan and tegoprazan had an advantage against other regimens including H2RAs, isomer PPIs, traditional PPIs, AHB, and new PPIs. Even in some subgroups, such as language classification (English), types of study design (crossover-RCT), age (?40?years), BMI (18.5-24.9?kg/m2 ), continent (Asia and North America), disease status (health), the duration of therapy (2?weeks), and time of administration (at daytime or at night-time), the nocturnal acid-inhibitory effect of vonoprazan or tegoprazan were better than most regimens, even AHB and new PPIs.

(Pubmed Central) - Oct 14, 2023 P3 Considering the potential effectiveness of tegoprazan as an acid-suppressing therapy and the possibility of type II error due to a low number of included patients herein, prospective, large-scale, multi-center studies with a higher dose of tegoprazan for a prolonged duration are required to elucidate the efficacy of tegoprazan in patients with LPRD.

Preclinical, Journal: Carcinogenicity assessment of tegoprazan in Sprague-Dawley (Crl:CD) rats and ICR (Crl:CD1) mice. (Pubmed Central) - Jul 17, 2023 Overall, tegoprazan induced gastric enterochromaffin-like (ECL) cell tumors in SD rats, but did not produce any treatment-related statistically significant increase in the incidence of neoplasms relevant to humans when administered to SD rats and CD-1 mice by gavage at doses up to 300 and 150 mg/kg/day, respectively. Gastric ECL cell tumors are thought to be induced by the exaggerated indirect pharmacological effect of tegoprazan, similar to that reported for proton pump inhibitors (PPIs) and other P-CABs.
