A campaign is in an "In-analysis" state, how does it get moved back to a "draft" state?

When a campaign is in an in-analysis state some form previews may be unavailable. If the campaign is not ready to be live and changes still need to be made it will need to be moved back to a draft state. To do this the campaign will need to be published momentarily, then it can be moved back to a draft state.

The option to publish and move to a draft will be found under campaign settings > basics near the top right corner.
