What are adaptive trial designs?

Adaptive trial designs are like having a game plan that changes as you play, so you can win faster and smarter.

Imagine you're trying to find the best ice cream flavor in the whole world. Instead of tasting every single flavor one by one, you start with a few favorites and see which ones people like most. Then, based on what you learn, you pick more flavors that look promising and skip the ones that aren’t so good. This way, you don’t waste time trying all 31 flavors, just the best ones.

In regular trials, you decide everything before you start: who joins, how long it takes, and what you’re testing. But with adaptive designs, you can change things as you go, like adding more people, switching up the test groups, or even stopping early if something is clearly working.

This method saves time and money because it learns from each step. It's like having a smart friend who helps you figure out the best path without making you try every possible option. Adaptive trial designs are like having a game plan that changes as you play, so you can win faster and smarter.
