Sceptical rather than excited about the triple agonist, and I would like somebody to talk me out of the scepticism with data rather than enthusiasm.

For anyone tracking the class: GLP-1 alone gets you appetite, GLP-1 plus GIP adds tolerability and lipid handling, and adding glucagon adds expenditure and liver-fat reduction. Each addition also adds a receptor system that can generate side effects.

The question I want answered is what the phase 2 dropout pattern implies about how the phase 3 tolerability will read.

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

Short answer first, then the reasoning. Take it one variable at a time. Almost every unanswerable question in these threads is unanswerable because three things changed in the same fortnight, and no amount of subsequent argument can untangle them after the fact.

No disagreement with kate.chem. One condition attached. The phase 2 numbers were about 24% mean weight loss at 48 weeks on the top dose, with the curve still descending at the end of the study. A curve that has not flattened is a real finding, but it also means the true plateau is unknown, and phase 2 populations are small and selected.

Second this. I had assumed I was the exception until I read this.

Clinical perspective, offered as context rather than as advice. The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either. Those three things can all be true at once, and most arguments here are two people holding different parts of that.
