study of vedolizumab following multiple intravenous doses in patients with ulcerative colitis

Conditions: Ulcerative Colitis

Summary: the main objectives of this study were to evaluate the safety, tolerability, pharmacokinetics (pk), and pharmacodynamics (pd) of multiple doses of vedolizumab in patients with ulcerative colitis (uc).

at the end of the study, eligible participants could enroll and receive treatment and follow-up in study c13004 (nct00619489). participants who did not proceed into study c13004 were followed by telephone contact at 6-month intervals for 2 years after the last administration of study treatment to collect reports of adverse events, including colectomy, severe infections \[including progressive multifocal leukoencephalopathy (pml)\], and dysplasia/cancer.
