Asking directly, because I could not find a straight answer: Why an oral GLP-1 agonist is a formulation achievement more than a chemistry one — one year on

A follow-up question about oral GLP-1 agonist that I did not know to ask the first time.

The earlier thread answered what I asked. What I should have asked is below, and I think it is the one that matters.

PIONEER 6 is the cardiovascular outcome trial for oral semaglutide and it enrolled a diabetes population at high cardiovascular risk. Quoting it outside that population is an extrapolation.

Post #2 is right about the mechanism and I think understates the practical bit.

Taking the oral product with more water than instructed reduces absorption rather than helping it. That is counter-intuitive and it is one of the few dosing instructions in this field with a clear pharmacokinetic basis.

Two people can read the same figure differently here and both be reasonable.

IRenaudin, post #2: PIONEER 6 is the cardiovascular outcome trial for oral semaglutide and it enrolled a diabetes population at high cardiovascular risk. Quoting it outside that population is an extrapolation. Go to post

Taking post #6 at face value and following it one step further.

Trial adherence in an oral trial with strict administration requirements is genuinely worse than trial-published data often suggests. That is why the exposure variability in oral formulations is mentioned repeatedly in the discussions here.

Genuinely open to being wrong about this one.

Oral semaglutide's bioavailability is low and variable, which is why the dose numbers are an order of magnitude different from the injectable. That is a formulation consequence and not a difference in potency.
