Certain Agreements:

Principal Investigators are NOT employed by the organization sponsoring the study.

There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.

The agreement is:

	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed. Restriction Description: Clinical Study Agreement. Most restrictive provision - PI will not publish results until after first of: multicenter publication is published or 24 months from study end. Thereafter, PI may publish his results. PI must provide copy of proposed publication to sponsor for pre-review. If sponsor requests, PI must delete sponsor confidential information before publication and/or delay publication for 90 days so sponsor can file for patents or take other action to protect its patent rights.
