Title: | Detection of Fraud in a Clinical Trial Using Unsupervised Statistical Monitoring | Authors: | de Viron, Sylviane Trotta, Laura Schumacher, Helmut Lomp, Hans-Juergen Hoppner, Sebastiaan Young, Steve BUYSE, Marc |
Issue Date: | 2022 | Publisher: | SPRINGER HEIDELBERG | Source: | Therapeutic Innovation and Regulatory Science, 56, p. 130-136 | Abstract: | Background A central statistical assessment of the quality of data collected in clinical trials can improve the quality and efficiency of sponsor oversight of clinical investigations. Material and Methods The database of a large randomized clinical trial with known fraud was reanalyzed with a view to identifying, using only statistical monitoring techniques, the center where fraud had been confirmed. The analysis was conducted with an unsupervised statistical monitoring software using mixed-effects statistical models. The statistical analyst was unaware of the location, nature, and extent of the fraud. Results Five centers were detected as atypical, including the center with known fraud (which was ranked 2). An incremental analysis showed that the center with known fraud could have been detected after only 25% of its data had been reported. Conclusion An unsupervised approach to central monitoring, using mixed-effects statistical models, is effective at detecting centers with fraud or other data anomalies in clinical trials. | Notes: | De Viron, S (corresponding author), CluePoints SA, Ave Albert Einstein,2a, B-1348 Louvain La Neuve, Belgium. sylviane.deviron@CluePoints.com |
