17 and 18 Consistent with the expected lack of effect on CNS immune surveillance owing to the gut-selective blockade of lymphocyte trafficking with vedolizumab,20 and 22 no PML cases have been identified in the vedolizumab development program to date. As of June 27, 2013, there were 3129 patients with CD or UC who had received vedolizumab in 11 clinical studies (including GEMINI 1, 2, 3, and the GEMINI long-term extension study) for a median of 313 days (mean, 481 days; range, 1–1977 days). Accounting for a pharmacologic effect duration of approximately 16 weeks after the last vedolizumab dose, 995 of these patients had been exposed to vedolizumab NADPH-oxidase inhibitor for at least 24 months. If the incidence of PML in patients
receiving vedolizumab was similar to that in patients with multiple sclerosis receiving natalizumab (ie, >1 case in 500 patients) before the application of known risk-stratification factors (ie, therapy duration, previous immunosuppressive use, and JC virus seropositivity),17 it is estimated that 6 to 7 cases would have been seen among vedolizumab-exposed patients. Although no PML cases have been reported in
the integrated vedolizumab safety database, additional longer-term observational data are needed to exclude any potential of developing PML as a result of vedolizumab exposure. In conclusion, vedolizumab was not statistically superior to placebo in achieving clinical remission at week 6 among patients with moderately to severely active CD and previous TNF antagonist failure. Several prespecified outcomes Quizartinib datasheet suggest that vedolizumab may lead to clinical remission in TNF antagonist–naive patients with CD and at 10 weeks in TNF antagonist–failure patients.
These clinically relevant response kinetics have potential implications for bridging induction therapy to vedolizumab maintenance therapy, which has established efficacy, in patients Urease with this lifelong condition. The safety profile of vedolizumab was generally similar to that of placebo in this short-term study and was consistent with that of longer-term vedolizumab use in previous studies.
