Een onderzoek naar TAK-279 bij volwassen deelnemers met gegeneraliseerde pustulaire psoriasis of erythrodermische psoriasis
Een fase 3, open-label, multicenter onderzoek om de werkzaamheid, veiligheid en verdraagbaarheid van TAK-279 bij volwassen proefpersonen met gegeneraliseerde pustuleuze psoriasis of erytrodermische psoriasis te evalueren
The main aim of this study is to check if TAK-279 improves symptoms of With Generalized Pustular Psoriasis (GPP) or Erythrodermic Psoriasis (EP) and side effect from the study treatment or TAK-279.
All participants will be assigned to study treatments of TAK-279 and will be treated with TAK-279 if the participants meet the study rules.

Percentage of Participants Who Achieved a Static Physician's Global Assessment (sPGA) of Clear (0) or Almost Clear (1) With a Greater Than or Equal to (>=) 2-Point Decrease From Baseline at Week 16
Tijdsspanne: At Week 16
|
The sPGA is a 5-point scale of an average assessment of all psoriatic lesions based on erythema, scaling, and induration. The average of the 3 scales, rounded to the nearest whole number, is the final sPGA score. The sPGA score ranged from 0 to 4 (0 = Clear; 1 = Almost clear; 2 = Mild; 3 = Moderate; 4 = Severe). Higher scores indicated more severe disease activity. 'Clear' and 'Almost clear' included all participants who scored a 0 or 1. |

|
|
Percentage of Participants Who Achieved >=75 Percent (%) Improvement From Baseline in Psoriasis Area and Severity Index (PASI) Score at Week 16
Tijdsspanne: At Week 16
|
PASI is a measure of the average redness, thickness, and scaliness of psoriatic skin lesions (each graded on a 0 to 4 scale; 0 = none to 4 = very severe), weighted by the area of involvement (head, upper extremities, trunk, and lower extremities). The PASI produced a numeric score that ranged from 0 to 72, with higher PASI scores denoting more severe disease activity. Percentage of participants showing at least 75% improvement in PASI score relative to baseline PASI score were reported. |

Percentage of Participants With a Baseline Dermatology Life Quality Index (DLQI) Score >=2 Who Achieved DLQI Score of 0 or 1 at Weeks 16 and 52
Tijdsspanne: At Weeks 16 and 52
|
The DLQI is a 10-item validated questionnaire completed by the participant or caregiver used to assess the impact of skin disease on the participant's quality of life (QoL) during the previous week. The 10 questions cover the following topics: symptoms, embarrassment, shopping and home care, clothes, social and leisure, sport, work or study, close relationships, sex, and treatment. Each question is scored from 0=not at all, 1=a little, 2=a lot, and 3=very much, giving a total score ranging from 0 to 30. A high score is indicative of a poor QoL. DLQI scores indicated: 0-1 (no effect on participant's life), 2-5 (small effect on participant's life), 6-10 (moderate effect on participant's life), 11-20 (very large effect on participant's life), 21-30 (extremely large effect on participant's life). The results will be disclosed during final posting. |

Change From Baseline in Nail Psoriasis Severity Index (NAPSI) at Weeks 16 and 52 Among Participants With Nail Involvement at Baseline
Tijdsspanne: Baseline, Weeks 16 and 52
|
The NAPSI quantifies the severity of nail psoriasis by evaluating the presence or absence of psoriatic manifestations on the nail matrix (pitting, leukonychia, red spots on the lunula, crumbling) and nail bed (onycholysis, splinter hemorrhages, subungual hyperkeratosis, oil drop [salmon patch dyschromia]). Each nail was scored for both nail matrix and nail bed psoriasis for each quadrant (ranging from 0 [absence of psoriasis] to 4 [presence of psoriasis in all 4 quadrants]). The total NAPSI score equals the sum of scores for all fingernails evaluated and ranged from 0 to 80. Higher scores indicated more severe psoriasis. The results will be disclosed during final posting. |

Percentage of Participants With Generalized Pustular Psoriasis Who Achieved a Generalized Pustular Psoriasis Global Assessment (GPPGA) Pustulation Subscore of No Visible Pustules (0) at Weeks 16 and 52
Tijdsspanne: At Weeks 16 and 52
|
The GPPGA is a common endpoint in clinical studies of GPP and is a skin-based scoring system. The GPPGA is a clinician assessment of overall GPP severity based on a modified PGA. The severity of pustules, erythema, and scaling of GPP lesions was assessed. The 5 grades of severity for erythema, scaling, and pustulation corresponded to 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe. The GPPGA score was based on averaging the individual scores for erythema, scaling, and pustulation and ranged from 0 to 4. Higher scores indicated more severe GPP. The results will be disclosed during final posting. |

Percentage of Participants With Generalized Pustular Psoriasis Who Achieved >=75% Improvement From Baseline in Generalized Pustular Psoriasis Area and Severity Index (GPPASI) Score at Weeks 16 and 52
Tijdsspanne: At Weeks 16 and 52
|
The GPPASI is a common endpoint in clinical studies of generalized pustular psoriasis (GPP) and is a skin-based scoring system. The GPPASI is a modified composite index and an adaptation of the PASI score. The induration component was substituted with a pustule component, with an overall score ranging from 0 (least severe) to 72 (most severe). Higher scores indicated more severe GPP. The 5 grades of severity for erythema, scaling, and pustulation corresponded to 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe. The score for each body region was calculated as the product of the sum of severity scores and the corresponding BSA score for erythema, scaling, and pustulation, multiplied by a weighting factor for each body region. The total GPPASI score was determined as the sum of the individual scores from all body regions. The results will be disclosed during final posting. |

Change From Baseline in Japanese Dermatological Association Severity Index (JDASI) Score at Weeks 16 and 52 for Participants With Generalized Pustular Psoriasis
Tijdsspanne: At Weeks 16 and 52
|
The Japanese Dermatological Association Severity Index (JDASI) assessed systemic symptoms based on laboratory changes. With the JDASI, the skin was evaluated using 3 criteria: (1) erythema area overall, (2) erythema area with pustules, and (3) oedema area. Scoring ranged from 3 to 0 (severe, moderate, mild, none), with a maximum of 9 points. For systemic involvement, pyrexia, white blood cell count, C-reactive protein (CRP), and serum albumin were assessed, with scores ranging from 2 to 0 and a maximum of 8 points. The total JDASI score for GPP was the sum of both categories and was categorized as severe (17-11 points), moderate (10-7 points), or mild (0-6 points). Higher scores indicated more severe GPP. The results will be disclosed during final posting. |
