Reading the phase 2 write-up next to the injectable trials, and the comparison people keep making does not survive putting the two protocols side by side.

What I actually want to know is whether a non-peptide oral agonist can match injectable exposure in practice, or whether the convenience is bought with a lower ceiling.

Practical detail welcome, however dull — the duller the better.

Taking the question as asked, rather than the general version of it. The gap between trial results and real-world results is consistent and it is not fraud. Trial participants get titration by protocol, scheduled contact, free drug and dietetic support; removing that infrastructure costs a few percentage points every time it has been measured. When your own curve sits below the published mean, that is the likeliest explanation before anything about you or your material.

That is correct as far as it goes, and here is where it stops going. The manufacturing argument is the underrated one. Peptide synthesis capacity has been the binding constraint on this entire class, and a small molecule is made in ordinary chemical plants. If it holds up in phase 3, the supply and price picture changes more than the efficacy picture does.

Agreed, and subgroup analyses deserve particular suspicion. With enough subgroups something is significant by chance, and pre-registered subgroups are a different animal from ones found afterwards.

Clinical perspective, offered as context rather than as advice. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.
