A Study to Determine the Optimal Dose of Tildrakizumab (SCH 900222/MK-3222) for the Treatment of Moderate-to-severe Chronic Plaque Psoriasis (P05495) (MK-3222-003)

18 gennaio 2019 aggiornato da: Merck Sharp & Dohme LLC

Randomized, Double-Blinded, Placebo-Controlled, Parallel-Design, Dose-Range Finding Study of Subcutaneous Tildrakizumab (SCH 900222/MK-3222) in Subjects With Moderate-to-Severe Chronic Plaque Psoriasis (Study P05495)

This is a response-driven study of tildrakuzumab for the treatment of moderate to severe chronic plaque psoriasis. The primary study hypothesis is that one or more doses of tildrakizumab will be superior to placebo for the treatment of psoriasis.

Intervento / Trattamento

Descrizione dettagliata

Each participant will be enrolled in the trial for approximately 72-76 weeks. Each participant will receive assigned treatment at Weeks 0 and 4 in Part I. At Week 16, the dosage of treatment the patient is assigned to may be adjusted based on the Psoriasis Area and Severity Index (PASI) 75 response (responder vs non-responder). Participants will receive study medication once every 12 weeks during Part 2 (Weeks 16 to 52); no participants will receive placebo in Part 2. Part 3 is an observational period and each subject will continue to be monitored on a monthly basis through Week 72. Subjects will not receive any study medication during Part 3.

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Percentage of Participants With a Psoriasis Area and Severity Index (PASI)75 Response at Week 16
Lasso di tempo: Week 16
The PASI score measures the severity and extent of psoriasis. Using a scale of 0=none to 4= very severe, each body region (head, trunk, arms, and legs) is rated for redness, thickness, and scaling of the largest psoriatic area in that region producing a Lesion Score. The percentage of the area affected by disease is then estimated, ranging from 0 = no lesions to 6 = 90-100% of the region is covered providing an Area Score. Then, the Lesion Score and Area Score for each region are multiplied, producing 4 subtotals. The 4 region subtotals are multiplied by a standardized percentage of body surface area for that region (head = 0.1, trunk = 0.3, arms=0.2, and legs = 0.4); these four region calculations are added to provide the final PASI score, ranging from 0 = no disease to 72 = maximal disease). PASI 75 response was defined as >=75% improvement in PASI score when compared to the baseline score.
Week 16
Number of Participants Experiencing Adverse Events
Lasso di tempo: Up to 72 weeks
An adverse event is any unfavorable and unintended change in the structure, function, or chemistry of the body whether or not considered related to the study treatment.

Lasso di tempo: Up to 52 weeks
An adverse event is any unfavorable and unintended change in the structure, function, or chemistry of the body whether or not considered related to the study treatment. Participants may be discontinued from study drug due to adverse events, but remain on the study.

Week 12
Percentage of Participants With Physician's Global Assessment (PGA) of "Cleared" or "Minimal" at Week 16
Lasso di tempo: Week 16
The PGA is used to determine the overall severity of a subject's psoriasis lesions at a given time point. Overall lesions will be graded for induration, erythema, and scaling on a scale from 0 to 5. The sum of the 3 scales will be divided by 3 to obtain the PGA score. PGA is assessed as: 0= Cleared, except for residual discoloration. 1= Minimal, majority of lesions have individual scores that average . 2 =Mild, majority of lesions have individual scores that average 2. 3= Modreate, majority of lesions have individual scores that average 3. 4= Marked, majority of lesions have individual scores that average 4. 5= Severe, majority of lesions have individual scores that average 5.

Lasso di tempo: Week 16
The DLQI is a 10-item questionnaire that measures how much participant skin problems have affected their life. Responses range from 0=Not at all to 3=Very much. The DLQI is broken down into 6 subscales: Symptoms and feelings (range 0-6), Daily activities (range 0-6), Leisure (range 0-6), Work and school (range 0-3), Personal relationships (range 0-6), and Treatment (range 0-3). DLQI subscales were summed to yield the DLQI total score, which could range from 0 to 30. For both DLQI subscales and DLQI total score, a higher score indicated a greater negative impact on life.
