Detaljert beskrivelse
In the result of recent meta-analysis, there was no improvement in symptoms with the first administration of PPI in about 75% of GERD patients, and symptoms were still sustained in about 50% of patients after administration of more than 3 days. Especially the nocturnal secretion of gastric acid was not effectively inhibited, and about 25% of GERD patients could not achieve the proper therapeutic effects even after PPI treatment twice daily for 4-8 weeks.
YH4808, as a selective K+- competitive acid blocker (P-CAB), is no need for activation by gastric acid since it competitively inhibits proton pump with K+. Thus, the inhibition of gastric acid secretion by YH4808 is prompt and effective. In addition, the inhibitive effect of gastric acid secretion by stimulation of histamine is proved to be more powerful than PPI (esomeprazole) and sustained in in-vitro/in-vivo model, and 24-h inhibition of gastric acid secretion and especially nocturnal inhibition of gastric acid secretion was observed to be superior to esomeprazole with repeat doses for 7 days in healthy volunteers.
Based on these nonclinical and clinical outcomes, an exploratory phase-II clinical trial is to be conducted to determine the proper treatment dose and administration method of YH48084 for GERD patients.
