Pizensy: animal efficacy model or human cells?

lactitol · Osmotic laxative

Efficacy evidence

Normal rats: increased small intestine contents (osmotic effect), independent of fermentation

“In pharmacology studies in rats, following oral administration, lactitol increased the weight of the contents of the small intestine and fermentation was not necessary for lactitol-induced osmotic effects in the small intestine.”

Why that model

Not stated in public reviews

Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.

Reviewer's view of the efficacy data

FDA: no approvability issues from the nonclinical perspective

“From the nonclinical perspective, there are no approvability issues.”
