This gets cited here weekly, usually second-hand, so it is worth setting out what it does and does not establish.
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.
Where I think it is weakest: the population was selected and supported in ways a real cohort is not, so I would read the effect size as a ceiling rather than an expectation.
The question I want answered is whether a non-peptide oral agonist can match injectable exposure in practice, or whether the convenience is bought with a lower ceiling. Tell me what I have not thought of.

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.

Pushing back on BariatricNurseD here. Small molecule does not automatically mean cheap. Price is set by what the market will bear and by patent life, not by cost of goods, and I would not assume the savings reach patients.

Shop Reference StandardsShort answer first, then the reasoning. Orforglipron is a small molecule rather than a peptide, which is the whole point: no SNAC absorption enhancer, no fasting window, no cold chain, and oral bioavailability in the tens of percent instead of around one. Phase 2 put it near 14.7% weight loss at 36 weeks on the top dose with a side-effect profile that looks like the injectables.

This is my experience too, for whatever a second data point is worth. The detail I would add is minor and it is already implied above.
