Two Florida Medical Study Coordinators Sentenced in Connection with Scheme to Falsify Clinical Trial Data

Department of Justice  /  Southern District of Florida  /  FOR IMMEDIATE RELEASE / Wednesday, October 19, 2022

MIAMI – A federal judge sentenced two Florida women to prison in connection with their participation in a conspiracy to falsify clinical trial data.

Senior U.S. District Judge Donald L. Graham of the Southern District of Florida sentenced Analay Rico, 37, of Fort Lauderdale, to 40 months in prison and Daylen Diaz, 44, of Miami, to 24 months in prison. The court also ordered Rico and Diaz to pay approximately $2.1 million in restitution.

According to court documents, Rico worked as a lead study coordinator for a clinical research firm based in Miami called Tellus Clinical Research (Tellus). Diaz was a research assistant and assistant study coordinator at Tellus. As part of their plea agreements, Rico and Diaz admitted that they agreed with others to defraud clients paying for clinical trial work intended to evaluate treatments for various medical conditions, including opioid dependency, irritable bowel syndrome and diabetic nephropathy. Among other things, Rico and Diaz admitted they falsified data to make it appear as though subjects were participating in the trials when, in truth, they were not.

“It’s disgraceful when a criminal preys upon patients in a health care setting,” said U.S. Attorney Juan Antonio Gonzalez for the Southern District of Florida. “We will prosecute perpetrators who do to the fullest extent of the law.”

“Clinical trials are essential in determining the safety and effectiveness of drug treatments,” said Principal Deputy Assistant Attorney General Brian M. Boynton of the Justice Department’s Civil Division. “The Justice Department will continue to work with its law enforcement partners to prosecute anyone who intentionally falsifies this critical data for personal profit.”

“Reliable and accurate data from clinical trials is the cornerstone of FDA’s evaluation of a new drug,” said FDA Assistant Commissioner for Criminal Investigations Catherine A. Hermsen. “Compromised clinical trial data could impact the agency’s decisions about the safety and effectiveness of the drug under review. We will continue to monitor, investigate and bring to justice those whose actions may subvert the FDA approval process and endanger the public health.”

Three co-conspirators previously pleaded guilty and were sentenced for their roles in the scheme. Eduardo Navarro, 53, of Miami, was sentenced to 46 months imprisonment; Duniel Tejeda, 36, of Clewiston, Florida, was sentenced to 30 months imprisonment; and Nayade Varona, 51, was sentenced to 30 months imprisonment.  Trial against three remaining defendants charged by indictment in connection with Tellus, Dr. Martin Valdes, 66, of Coral Gables, Florida, Fidalgis Font, 55, of Miami, and Julio Lopez, 55, of Hialeah, Florida, is currently set for Jan. 10, 2023.

The Food and Drug Administration’s Office of Criminal Investigations is investigating the case.

Trial Attorneys Lauren M. Elfner, Joshua D. Rothman and Wandaly Fernandez Garcia of the Civil Division’s Consumer Protection Branch are prosecuting the case. Assistant United States Daren Grove is handling asset forfeiture.

An indictment contains mere allegations and defendants are innocent unless and until found guilty in a court of law.
