Clinical Trial 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).

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Adverse Events	An adverse event (AE) is any untoward medical occurrence in a patient administered a pharmaceutical product, which does not necessarily have a causal relationship with the treatment. The investigator systematically collected information adequate to determine both the outcome and severity of the AE, and whether or not it was drug-related or met the criteria for classification as a serious adverse event (SAE). An SAE was defined as an AE that resulted in (or posed risk for) death, inpatient hospitalization (or prolonging hospitalization), or congenital, persistent or significant disability/incapacity.; The intensity for each AE was defined according to the following criteria: Mild: Awareness of sign or symptom, but easily tolerated Moderate: Discomfort enough to cause interference with normal daily activities Severe: Inability to perform normal daily activities.	From the first date of study drug administration through Day 253	Yes
Primary	Cmax: Maximum Observed Plasma Concentration of Vedolizumab on Days 1 and 85	Maximum observed plasma concentration (Cmax) is the peak plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve.	Days 1 and 85, prior to and 2, 12, 24, 48, and 72 hours after dosing.	No
Primary	Cmin: Minimum Observed Plasma Concentration of Vedolizumab	Minimum observed plasma concentration (Cmin) is the lowest plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve.	Day 85, prior to and 2, 12, 24, 48, and 72 hours after dosing.	No
Primary	Area Under the Plasma Concentration-Time Curve (AUC) for Vedolizumab	AUC was calculated for 3 time intervals during the study: AUC (Day 0-14): from administration on Day 0 to last quantifiable concentration on Day 14, selected to capture the AUC following the first dose of vedolizumab until administration of the second dose; AUC(Day 85-99): from administration on Day 85 to last quantifiable concentration on Day 99, selected to assess the amount of drug accumulation with the planned loading regimen by comparing it to AUC(Day 0-14); AUC(Day 85-141): from the first quantifiable concentration on Day 85 to the last quantifiable concentration on Day 141, selected to assess the drug exposure over an 8-week period	Days 0-14, Days 85-99, Days 85-141	No
Primary	Terminal Phase Elimination Half-life (t½) of Vedolizumab	Terminal phase elimination half-life (t½) is the time required for half of the drug to be eliminated from the plasma.	Pre-dose through Day 253	No
Primary	Maximum Drug Effect (Emax) of Vedolizumab as Measured by Percent Inhibition of the Act-1 Marker	The target of vedolizumab is a4ß7 integrin, a receptor found on inflammatory immune cells that guides these inflammatory cells to the gut and binds to the Mucosal Addressin Cell Adhesion Molecule-1 (MAdCAM-1) on gut endothelial cells. The extent of the a4ß7 receptor saturation by vedolizumab was assessed using the Act-1 binding interference assay. Act-1 is a mouse antibody similar to vedolizumab that also binds a4ß7 integrin. The assay measures the percent inhibition of the Act-1 due to the presence of vedolizumab binding.; Emax was calculated on Day 1, Day 85 and based on all available data.	Days 1, 2, 3, 4, 8, 15, 29, 43, 57, 71, 85, 86, 87, 89, 92, 99, 113, 127, 141, 155, 169, 183, 197, 211, 225, 239, and 253	No
Primary	Maximum Drug Effect (Emax) as Measured by Inhibition of the MAdCAM-1-Fc Marker	The target of vedolizumab is a4ß7 integrin, a receptor found on inflammatory immune cells that guides these inflammatory cells to the gut and binds to the mucosal addressin cell adhesion molecule-1 (MAdCAM-1) on gut endothelial cells. The extent of the a4ß7 receptor saturation by vedolizumab was assessed using the MAdCAM-1-Fc binding interference assay. MAdCAM-1-Fc is a fusion of human MAdCAM-1 with parts of a mouse monoclonal antibody. The assay measures the percent inhibition of the MAdCAM-1-Fc binding to a4ß7 integrin due to the presence of vedolizumab binding.; Emax was calculated on Day 1, Day 85, and based on all available data.	Days 1, 2, 3, 4, 8, 15, 29, 43, 57, 71, 85, 86, 87, 89, 92, 99, 113, 127, 141, 155, 169, 183, 197, 211, 225, 239, and 253	No
Primary	Area Under the Drug Effect Time Curve [AUEC(0-last)] as Measured by Inhibition of the ACT-1 Marker	AUEC (0-last) is the area under the drug effect-time curve until the last available time point. Mean percent inhibition over time [AUEC(0-last)] was determined for the Act-1 marker. Act-1 is a mouse antibody similar to vedolizumab that also binds a4ß7 integrin.	Days 1, 2, 3, 4, 8, 15, 29, 43, 57, 71, 85, 86, 87, 89, 92, 99, 113, 127, 141, 155, 169, 183, 197, 211, 225, 239, and 253	No
Primary	Area Under the Drug Effect Time Curve [AUEC(0-last)] as Measured by Inhibition of the MAdCAM-1-Fc Marker	AUEC (0-last) is the area under the drug effect-time curve until the last available time point. Mean percent inhibition over time [AUEC(0-last)] was determined for the MAdCAM-1-Fc marker. MAdCAM-1-Fc is a fusion of human MAdCAM-1 with parts of a mouse monoclonal antibody.	Days 1, 2, 3, 4, 8, 15, 29, 43, 57, 71, 85, 86, 87, 89, 92, 99, 113, 127, 141, 155, 169, 183, 197, 211, 225, 239, and 253	No
