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: The Sponsor recognizes the right of the investigator(s) to publish, but all publications must be based on data validated and released by the Sponsor. Any such scientific paper, presentation, or other communication concerning the clinical trial will first be submitted to the Sponsor, at least six weeks ahead of estimated publication or presentation, for written consent, which shall not be withheld unreasonably.
