Outcome Measures
Adverse Events
Limitations and Caveats
The primary and secondary outcome measures were originally planned to be assessed at 18 months. However, as the study was terminated early, an analysis was completed at 9 months instead, in a subset of subjects who had received 9 months of treatment.
More Information
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.
For this study, PIs are restricted from independently publishing results before completion of a single multicenter publication or one year after study completion, whichever occurs first. Baxter requires a review of results communications (e.g., for confidential information) ≥90 days prior to submission or communication. Baxter may request an additional delay of ≤60 days (eg, for intellectual property protection).
