An Open-label, Randomized, Parallel-Group, Phase I Study to Evaluate Pharmacokinetics, Efficacy and Safety Between Subcutaneous CT-P13 and Intravenous CT-P13 in Patients With Active Crohn's Disease and Active Ulcerative Colitis

Phase 1 randomized, open-label, multicenter, parallel-group study designed to evaluate efficacy, pharmacokinetics and safety between CT-P13 subcutaneous (SC) and CT-P13 intravenous (IV) in patients with active Crohn's Disease (CD) and active Ulcerative Colitis (UC).

Detailed Description

A new subcutaneous infliximab formulation is developed by Celltrion, Inc. as an alternative to the intravenous regimen where subcutaneous infliximab injection typically takes less than 2 minutes. The availability of a subcutaneous formulation of infliximab would increase the treatment options available to patients, particularly those wishing to self-administer their therapy. This Phase 1 randomized, open-label, multicenter, parallel-group study is designed to evaluate efficacy, pharmacokinetics and safety between CT-P13 SC and CT-P13 IV in patients with active CD and active UC.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Descriptive Statistics of Area Under the Concentration-time Curve (AUCτ) of Infliximab at Steady State (Part 1)
Time Frame: Week 22, 24, 26 and 28
For Part 1, the primary PK endpoint of the AUCτ at steady state between Week 22 and Week 30 was analyzed in patients who received all doses (full) of study drug up to Week 30 (prior to Week 30) in the PK population. All patients in SC cohorts were randomly assigned at Week 14 in a 1:1 ratio to either of Group A or B for PK monitoring visit period (Week 22 to Week 30). Therefore, AUCτ was calculated at Week 22 for Cohort 1: CT-P13 IV 5 mg/kg, Weeks 22 and 26 for Group A of SC cohorts, and Week 24 and 28 for Group B of SC cohorts.
Week 22, 24, 26 and 28
Analysis of Covariance Model (ANCOVA) of Observed Ctrough,week22 (Pre-dose Level at Week 22) (Part 2)
Time Frame: Week 22
For Part 2, the primary endpoint was to demonstrate that CT-P13 SC is non-inferior to CT-P13 IV, in terms of pharmacokinetics, as determined by the observed Ctrough,week22 (pre-dose level at Week 22).
Week 22

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Descriptive Statistics for Actual Value of Crohn's Disease Activity Index (CDAI) Score (Part 2 - CD)
Time Frame: up to Week 54
For evaluation of efficacy, the secondary endpoint was defined as descriptive statistics for actual value of CDAI score up to Week 54 between the CT-P13 SC and CT-P13 IV treatment groups in active CD patients. The total CDAI scores range from 0 to over 600 with higher scores indicating increased severity of disease. The index is the sum of 8 components multiplied by the relevant weight factor; number of liquid or very soft stools (x2), abdominal pain (x5), general well-being (x7), CD complications (x20), taking lomotil/opiates for diarrhea (x30), abdominal mass (x10), deviation of hematocrit (x6), and percentage deviation from standard weight (x1). Efficacy assessments were done prior to each study drug administrations. Results up to Week 6 in both arms represent efficacy resulting from CT-P13 IV (5 mg/kg) loading dose treatment.
up to Week 54
Proportion of Patients Achieving Clinical Response According to CDAI-100 Criteria (Part 2 - CD)
Time Frame: up to Week 54

For evaluation of efficacy, the secondary endpoint was defined as proportion of patients achieving clinical response according to CDAI-100 criteria up to Week 54 between the CT-P13 SC and CT-P13 IV treatment groups in active CD patients. Efficacy assessments were done prior to each study drug administrations. Results up to Week 6 in both arms represent efficacy resulting from CT-P13 IV (5 mg/kg) loading dose treatment.

Responder according to CDAI-100 criteria was defined as a decrease in CDAI score of 100 points or more from the baseline value.
up to Week 54
Descriptive Statistics for Actual Value of Partial Mayo Score (Part 2 - UC)
Time Frame: up to Week 54
For evaluation of efficacy, the secondary endpoint was defined as descriptive statistics for actual value of partial Mayo score up to Week 54 between the CT-P13 SC and CT-P13 IV treatment groups in active UC patients. The partial Mayo scores range from 0-9 with higher scores indicating increased severity of disease. The index is sum of the 3 subscores, each which range from 0 to 3; stool frequency, rectal bleeding and physician's global assessment. Efficacy assessments were done prior to each study drug administrations. Results up to Week 6 in both arms represent efficacy resulting from CT-P13 IV (5 mg/kg) loading dose treatment.
up to Week 54
Proportion of Patients Achieving Clinical Response According to the Partial Mayo Score (Part 2 - UC)
Time Frame: up to Week 54

For evaluation of efficacy, the secondary endpoint was defined as proportion of patients achieving clinical response according to the partial Mayo score up to Week 54 between the CT-P13 SC and CT-P13 IV treatment groups in active UC patients. Efficacy assessments were done prior to each study drug administrations. Results up to Week 6 in both arms represent efficacy resulting from CT-P13 IV (5 mg/kg) loading dose treatment.

Responder according to partial Mayo score was defined as a decrease from baseline in partial Mayo score of at least 2 points, with an accompanying decrease in the subscore for rectal bleeding of at least 1 point or an absolute subscore for rectal bleeding of 0 or 1.
up to Week 54
Descriptive Statistics of Observed Ctrough (Trough Concentration [Before the Next Study Drug Administration]) of Infliximab (Part 2)
Time Frame: up to Week 54
For evaluation of pharmacokinetics (PK), the secondary endpoint was defined as the analysis of trough concentration of infliximab up to Week 54. The samples were collected at Weeks 0, 2 and 6, and every 8 weeks up to Week 54. During PK monitoring visit (Weeks 22-30), samples were collected every 2 weeks according steady state PK sampling time point. All enrolled patient received CT-P13 IV infusions at Weeks 0 and 2. Patients in SC group were administered with CT-P13 SC at Week 6 and every 2 weeks thereafter up to Week 54. Patients in IV group were administered with CT-P13 IV at Week 6 and every 8 weeks thereafter up to Week 22. Then, CT-P13 IV was switched to CT-P13 SC at Week 30, and further doses with CT-P13 SC were given up to Week 54. No PK results were obtained at Weeks 6 and 14 for SC group and Weeks 12, 20, 24, 26 and 28 for IV group due to 2 weeks and 8 weeks dosing interval, respectively. All patients in PK population were analyzed according to the treatment they received.
up to Week 54
Descriptive Statistics for Actual Value in Fecal Calprotectin Concentration (Pharmacodynamic Parameter) (Part 2)
Time Frame: up to Week 54
For evaluation of pharmacodynamic (PD), the secondary endpoint was defined as concentration of Fecal Calprotectin (FC) between 2 treatment groups up to Week 54. The fecal samples for FC were collected at Weeks 0, 2 and 6, and every 8 weeks up to Week 54. All enrolled patients received CT-P13 IV infusions at Weeks 0 and 2. Then, patients in CT-P13 SC group were administered with CT-P13 SC at Week 6 and every 2 weeks thereafter up to Week 54. Patients in the CT-P13 IV group were administered with CT-P13 IV at Week 6 and every 8 weeks thereafter up to Week 22 (Weeks 14 and 22). And then, CT-P13 IV was switched to CT-P13 SC based on body weight at Week 30, and further doses with CT-P13 SC were given up to Week 54. All patients in the PD population were analyzed according to the treatment they received.
up to Week 54
