A pair of clinical research coordinators (CRC) in Florida pled guilty to taking part in a scheme engineered to falsify trial data at a Miami site, the Department of Justice (DOJ) reports.

Analay Rico of Fort Lauderdale and Daylen Diaz of Miami, who both worked as CRCs at Miami site Tellus Clinical Research, took plea agreements, admitting they defrauded clients paying the site for work on trials of opioid dependency, irritable bowel syndrome and diabetic nephropathy treatments. Among other things, the pair confessed to falsifying data from made-up trial participants, the DOJ said.

It appears the data falsification scheme was extensive across the Miami site. Three others working at Tellus previously pled guilty to participating in the plot, receiving prison sentences ranging from 30 to 46 months and orders to pay approximately $4.2 million in restitution. They, too, were making up data in an attempt to make it look like trials had active participants.

Another three defendants are scheduled for trial Sept. 27, according to the DOJ.
