What is being measured
The primary outcome is the main question the study is designed to answer.
Achievement of Psoriasis Activity and Severity Index (PASI75) Response at Week 12
Determining the PASI score involves the evaluation of erythema, infiltration, and desquamation and body surface area involvement over 4 body regions. These regions are the head, trunk, upper and lower extremities.
PASI75 response at Week 12 is defined as a decrease in PASI score at Week 12 from Baseline of at least 75 %.
Measured: Week 12
Achievement of a Physician's Global Assessment (PGA) of Clear or Almost Clear at Week 12
The overall severity of the disease was evaluated using the following 6-point scale:
5 = Severe: Very marked plaque elevation, scaling, and/or erythema. 4 = Moderate to severe: Marked plaque elevation, scaling, and/or erythema. 3 = Moderate: Moderate plaque elevation, scaling, and/or erythema. 2 = Mild: Slight plaque elevation, scaling, and/or erythema
1 = Almost clear: Intermediate between mild and clear 0 = Clear: No signs of psoriasis (post-inflammatory hyperpigmentation may be present)
Measured: Week 12
Secondary outcomes (9)
Time to Psoriasis Activity and Severity Index 50 (PASI50)
Time to PASI50 is defined as the time elapsed between the start of the Treatment Period (Week 0) and the first occurrence of PASI50 during the Treatment Period.
This variable is defined only for those patients who have achieved PASI75 at the end of the Treatment Period (Week 12).
Measured: During the 12-weeks Treatment Period
Time to Psoriasis Activity and Severity Index 75 (PASI75)
Time to PASI75 is defined as the time elapsed between the start of the Treatment Period (Week 0) and the first occurrence of PASI75 during the Treatment Period.
This variable is defined only for those patients who have achieved PASI75 at the end of the Treatment Period (Week 12).
Measured: During the 12-weeks Treatment Period
Time to Relapse
Time to relapse is defined as the time elapsed between the last dose and when maximal improvement in PASI from Baseline was reduced by > 50 %. This variable is defined only for those patients who have achieved PASI75 at the end of the Treatment Period (Week 12).
Measured: During the 12-weeks Treatment Period
Achievement of a Psoriasis Activity and Severity Index (PASI50) Response at Week 12
Determining the PASI score involves the evaluation of erythema, infiltration, and desquamation and body surface area involvement over 4 body regions. These regions are the head, trunk, upper and lower extremities.
PASI50 response at Week 12 is defined as a decrease in PASI score at Week 12 from Baseline of at least 50 %.
Measured: Week 12
Achievement of a Psoriasis Activity and Severity Index (PASI90) Response at Week 12
Determining the PASI score involves the evaluation of erythema, infiltration, and desquamation and body surface area involvement over 4 body regions. These regions are the head, trunk, upper and lower extremities.
PASI90 response at Week 12 is defined as a decrease in PASI score at Week 12 from Baseline of at least 90 %.
Measured: Week 12
Experience of a Rebound Effect Within 2 Months After Stopping Therapy
Rebound is defined as worsening of psoriasis over baseline value with more than 125 % or new pustular, erythrodermic or more inflammatory psoriasis within 2 months of stopping therapy.
Measured: Within 2 months of stopping therapy
Percent of Body Surface Area (BSA) Affected by Psoriasis at Week 12
Two methods were used for the evaluation of BSA:
- The area of one side of a subject's flat closed hand was used to represent 1 % to the total body surface area (BSA) to estimate the extent of skin involvement in subjects with psoriasis
- The rule of nines method assumed that the total BSA comprises head (9 %), anterior trunk (upper, 9 %; lower, 9 %), posterior trunk (upper, 9 %; lower, 9 %), each leg (anterior, 9 %; posterior, 9 %), each arm (9 %) and genitalia (1 %)
Measured: Week 12
Absolute Change From Baseline in the Body Surface Area (BSA) Affected by Psoriasis at Week 12
Two methods were used for the evaluation of BSA:
- The area of one side of a subject's flat closed hand was used to represent 1 % to the total body surface area (BSA) to estimate the extent of skin involvement in subjects with psoriasis
- The rule of nines method assumed that the total BSA comprises head (9 %), anterior trunk (upper, 9 %; lower, 9 %), posterior trunk (upper, 9 %; lower, 9 %), each leg (anterior, 9 %; posterior, 9 %), each arm (9 %) and genitalia (1 %) A positive value in Change from Baseline indicates an improvement from Baseline. The higher the positive value, the higher the change.
Measured: Baseline up to Week 12
Time to Discontinuation From the Treatment Period Due to Lack of Efficacy or Worsening of Psoriasis
Measured: During the 12-week Treatment Period

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Certolizumab Pegol in people with Chronic Plaque Psoriasis, run by UCB Pharma at 15 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 May 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 15 sites in Germany, France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 May 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Achievement of Psoriasis Activity and Severity Index (PASI75) Response at Week 12 (time frame: Week 12). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00245765, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 May 2019.
