Possible failures? Unforeseen SAE that didn't show up in the previous smaller trials. Unfortunate patient selection in the smaller trial that doesn't replicate in the larger trial. Negative effects on blood chemistry not seen in the smaller trial that shows up in the larger trial to a few subjects. Unforeseen interactions with other drugs that the subjects are taking.

There are lots of ways for a trial to fail. Most of which are not seen coming until they show up.

Am I suggesting that the trial will fail? No.

But you asked the question about ways the trial could fail. The risk of trial failure is low but not zero.
