The most important first step is to present your concerns to the trial investigators and/or sponsor in order to determine whether or not the misreporting you have identified is indeed misreporting.  If the misreporting is confirmed, the next step is to determine whether or not the trial investigators and/or sponsor intends to correct the record.

Once sufficient notice to the original investigators and sponsors has been made and you have documentation that shows or suggests the trial investigators and/or sponsor will not correct the record, the trial can be considered abandoned and you may consider restoring the trial through RIAT.
