The MHRA are the UK medicines regulatory agency. There are many branches, GMP, GCP, GDP, GLP. The latter being the 1st of the testing of new potential pharmaceuticals. GLP certificates are issued after routine inspection cycles, depending on the size of the testing company.
The preclinical programme consists of a myriad of in vitro and in vivo testing of test items for safety and efficacy. Every single Study has a study plan. Raw data and report, which is signed by the Study Director and Quality Assurance. Once some of the package has completed I.e. genotox, ADME, some in vivo toxicology studies, reproductive tox etc the CTA commences.
My guess is the CTA reviewers have requested that some of these studies are given a review versus the raw data, for compliance with GLP standards and drawn conclusions. This will take some time depending on what the reasons are (and number of specific studies requested).
The big question is what is the actual areas of concern that the RNS does not go into.
