研究概览
简要总结
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).
详细描述
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.

结局指标
主要结局
Terminal Phase Elimination Half-life (t½) of Vedolizumab
时间窗: Pre-dose through Day 253
Terminal phase elimination half-life (t½) is the time required for half of the drug to be eliminated from the plasma.
Number of Participants With Adverse Events
时间窗: From the first date of study drug administration through Day 253
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.
Cmin: Minimum Observed Plasma Concentration of Vedolizumab
时间窗: Day 85, prior to and 2, 12, 24, 48, and 72 hours after dosing.
Minimum observed plasma concentration (Cmin) is the lowest plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve.
Area Under the Plasma Concentration-Time Curve (AUC) for Vedolizumab
时间窗: Days 0-14, Days 85-99, Days 85-141
AUC was calculated for 3 time intervals during the study: 1. 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 2. 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) 3. 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
Area Under the Drug Effect Time Curve [AUEC(0-last)] as Measured by Inhibition of the MAdCAM-1-Fc Marker
时间窗: 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
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.
Cmax: Maximum Observed Plasma Concentration of Vedolizumab on Days 1 and 85
时间窗: Days 1 and 85, prior to and 2, 12, 24, 48, and 72 hours after dosing.
Maximum observed plasma concentration (Cmax) is the peak plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve.
Maximum Drug Effect (Emax) of Vedolizumab as Measured by Percent Inhibition of the Act-1 Marker
时间窗: 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
The target of vedolizumab is α4β7 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 α4β7 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 α4β7 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.
