There is NOT 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.

Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Thirty (19.2%) specimens had to be rejected due to contamination that occurred during the analysis process. During the HPV DNA analysis, there were protocols for different aspect of controls during the analysis which needed to be negative.
