On 20 September 2012, the European Medicines Agency completed a review of nine centrally and nationally authorised medicines, following concerns over the conduct of laboratory analyses of certain studies submitted as part of their marketing-authorisation applications. The studies concerned were all conducted at the Cetero Research facility in Houston, Texas, United States.

The Agency's Committee for Medicinal Products for Human Use (CHMP) concluded that for seven medicines (Cilazapril Teva, Fenofibrato Pensa, Fenofibrato Ranbaxy, Leflunomide Actavis, Leflunomide Apotex, Ribavirin Teva and Ribavirin Teva Pharma B.V.) some of the studies that supported their authorisation could not be considered reliable. In the absence of reliable data, the CHMP recommended that their marketing authorisation should be suspended until adequate data are provided. For Temodal and Tygacil, the findings have no impact on the benefit-risk balance of these medicines and no further action is needed.

At the request of the company that markets Fenofibrato Pensa and Fenofibrato Ranbaxy, the CHMP re-examined the initial opinion for these medicines, and confirmed its previous recommendation on 13 December 2012.
