Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

CT-P43, containing the active ingredient ustekinumab, is a human IgG1κ monoclonal antibody that is being developed as a biosimilar medicinal product to the reference product, Stelara. The purpose of this study is to demonstrate similar efficacy and safety of CT-P43 and Stelara in patients with moderate to severe plaque psoriasis.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 76 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

- Patient has had diagnosis of plaque-type psoriasis for at least 24 weeks.

Exclusion Criteria:

  • Patients diagnosed with forms of psoriasis other than plaque-type.
  • Patients previously received ustekinumab or a biosimilar of ustekinumab.
  • Patient who has allergies to the active substance or any of the excipients of ustekinumab or study drug, or patients with a hypersensitivity to immunoglobulin products or natural rubber and latex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: CT-P43
All patients who were initially randomized to the CT-P43 group on Day 1 (Week 0) will continue their treatment with CT-P43 until Week 40.
Biological: CT-P43
45mg or 90mg dose subcutaneous administration
Active Comparator: Stelara
Patients who were initially randomized to Stelara group on Day 1 (Week 0) will be randomized again in a ratio of 1:1 to either continue Stelara or undergo transition to CT-P43 prior to dosing at Week 16. Thereafter, patients will continue their treatment until Week 40.
Biological: CT-P43
45mg or 90mg dose subcutaneous administration
Biological: Stelara
45mg or 90mg dose subcutaneous administration

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Mean Percent Improvement From Baseline in PASI Score at Week 12
Time Frame: From baseline to Week 12
The percent improvement from baseline in Psoriasis Area and Severity Index (PASI) score at Week 12. PASI score can range from 0 (no psoriasis) to 72 (severe psoriasis).
From baseline to Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The PASI Scores at Week 12
Time Frame: Week 12
The Psoriasis Area and Severity Index (PASI) score at Week 12. PASI score can range from 0 (no psoriasis) to 72 (severe psoriasis).
Week 12
The Mean Percent Improvement From Baseline in PASI Score Through Week 52
Time Frame: Through Week 52
The percent improvement from baseline in Psoriasis Area and Severity Index (PASI) score through Week 52. PASI score can range from 0 (no psoriasis) to 72 (severe psoriasis).
Through Week 52
The Number of Patients Achieving PASI 50, PASI 75, PASI 90, and PASI 100 Responses at Week 12
Time Frame: Week 12
The number of participants achieving at least 50%/75%/90%/100% improvement from baseline in Psoriasis Area and Severity Index (PASI) at Week 12. PASI score can range from 0 (no psoriasis) to 72 (severe psoriasis).
Week 12
The Number of Patients With sPGA Score of Clear (0) or Almost Clear (1) at Week 12
Time Frame: Week 12
The sPGA is a 5-point score ranging from 0 to 4, based on the physician's assessment of the erythema, average thickness, and scaling of all psoriatic lesions at a given time point. The sum of the 3 scales will be divided by 3 to obtain a final sPGA score.
Week 12
The Change From Baseline in Dermatology Life Quality Index (DLQI) Through Week 52
Time Frame: Through Week 52
This DLQI is a 10-item patient-reported outcome questionnaire that, in addition to evaluating overall QoL, can be used to assess 6 different aspects that may affect QoL: symptoms and feelings, daily activities, leisure, work or school performance, personal relationships, and treatment. Total scores range from 0 to 30 (less to more impairment).
Through Week 52
