Read the primary source rather than the write-up and the two do not agree, so here is what is actually in it.
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.
Where I think it is weakest: the follow-up is short relative to how long people actually take these drugs, so durability is an assumption here rather than a finding.
What I actually want to know 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.
Figures above are from the primary publication rather than the press summary. If a number here disagrees with one you have, post yours and we will work out which of us is reading a secondary source.

True, and it depends on a baseline nobody has stated. Without knowing where someone started, the same number can be an excellent result or a disappointing one.

I would rather people stopped quoting the 24% as if it were a licensed outcome. It is a phase 2 result in a few hundred participants with no cardiovascular endpoint and no long-term safety data, and this board has a habit of treating pipeline numbers as settled.
If somebody has the primary source to hand I would rather cite it than paraphrase it.

Glucagon receptor agonism raises energy expenditure and drives hepatic fatty-acid oxidation, and its hyperglycaemic tendency is offset by the GLP-1 arm's insulin secretagogue effect. Net result: intake down from GLP-1/GIP, expenditure up from glucagon, glycaemia neutral or improved. It is a balancing act, and it is why the liver-fat results are the most interesting part of the dataset.

Can confirm. Same sequence, different timescale.
