RESUMO
BACKGROUND: The aim of this study was to evaluate how many MS patients treated with an approved DMD in routine care would have fulfilled the inclusion and exclusion criteria of phase III clinical trial and would therefore be eligible for the respective drug trial. Further, adverse events and disease progression for these patients were compared. METHODS: A comparison of patients fulfilling phase III clinical trial inclusion and exclusion criteria and those who do not with regard to sociodemographic and clinical characteristics, adverse events and disease progression. Database was the REGIMS register, a national, prospective, observational, clinical multicentre registry. 1248 MS Patients were included. RESULTS: 27.2% patients would have been eligible for inclusion into a phase III clinical trial of their indication. Patients who did not meet the criterion age are more likely to have a serious adverse event (SAE), whereas patients who did not fulfil the criterion relapse had a significant lower occurrence of an adverse event (AE). Non-fulfilment of other inclusion criteria (EDSS Score; medication history and MS type) did not show any significant differences in drug safety variables, AE and SAE. CONCLUSION: Our results suggest that a low transferability of phase III clinical trial criteria, to patients in routine care with the exception of age, does not imply a higher risk with regard to adverse and serious adverse events.
