Not yet recruiting
Conditions
Enthesitis-related Arthritis (ERA)
Juvenile Psoriatic Arthritis (JPsA)
Registration Number
NCT07190053
Lead Sponsor
Novartis Pharmaceuticals
Brief Summary

The goal of this study is to understand the long-term treatment strategies in children and adolescents diagnosed with ERA or JPsA who received secukinumab and achieved inactive disease and to evaluate the long-term treatment effectiveness of secukinumab in the ERA or JPsA patients in the postauthorization setting.

Detailed Description

This is a multicenter, non-interventional cohort study with a combined data collection principle based on secondary use of data and primary data collection from the existing BIKER registry among pediatric patients with a recorded diagnosis of ERA or JPsA who have been treated with secukinumab.

The primary objective of this study is to characterize potentially less demanding long-term treatment strategies (e.g., dose tapering, treatment withdrawal followed by treatment re-initiation as needed) and to characterize their effectiveness (evaluated by occurrence of disease flares) in children and adolescents with Enthesitis-Related Arthritis (ERA) or Juvenile Psoriatic Arthritis (JPsA) categories documented in the German Biologics in pediatric rheumatology (BIKER) registry who received secukinumab and achieved inactive disease.

The date of first treatment/prescription of secukinumab will be considered as the index date. The baseline period to evaluate the demographic and clinical characteristics includes the index date and up to 1 year prior to the index date; if no record is available at the index date whichever record is closest to the index date will be used. For JIA-related variables, such as JIA-related manifestations, the evaluation will not have a specific time limit prior to the index date."

Number of patients achieving Juvenile Idiopathic Arthritis (JIA) American College of Rheumatology (ACR) 30/50/70/90 criteria at follow-upEvery 3 months after index date until the end of follow-up or until secukinumab discontinuation or switching to another biologic, whichever occurs first, up to 5 years

The adapted ACR Pediatric 30/50/70/90 criteria was used to determine efficacy defined as improvement from baseline of at least 30/50/70/90% respectively in at least 3 of the following 6 components

* Physician's Global Assessment of disease activity on a 0-100 mm VAS from 0 mm = no disease activity to 100 mm = very severe disease activity.

* Parent's or patient's Global Assessment of Subject's overall wellbeing on a 0-100 mm VAS from 0 mm= very well to 100 mm= very poor.

* Functional ability: Childhood Health Assessment Questionnaire (CHAQ©)

* Number of joints with active arthritis using the ACR definition (The ACR definition of active arthritis is any joint with swelling, or in the absence of swelling, limitation of motion accompanied by either pain on motion or tenderness not due to deformity)

* Number of joints with limitation of motion

* Laboratory measure of inflammation: CRP (mg/L)

Number of patients achieving at least minimal disease activityEvery 3 months after index date until the end of follow-up or until secukinumab discontinuation or switching to another biologic, whichever occurs first, up to 5 years

Patients who achieved minimal disease activity and inactive disease can be defined based on JADAS-10 score. JADAS-10 is a composite disease activity score for JIA including four measures:

* physician's global assessment of disease activity (NRS)

* parent/guardian's or patient's global assessment of overall wellbeing (NRS)

* number of joints (up to 10) with active arthritis

* CRP/ESR, whichever is available

Number of patients achieving inactive diseaseEvery 3 months after index date until the end of follow-up or until secukinumab discontinuation or switching to another biologic, whichever occurs first, up to 5 years

Inactive disease is achieved if either of the following two criteria is fulfilled:

* Wallace et al (2011) ACR criteria for inactive disease:

* no joints with active arthritis

* no active uveitis

* normal CRP/ESR, or if elevated, not attributable to JIA

* physician's global assessment of disease activity ≤ 1 (NRS)

* duration of morning stiffness attributable to JIA ≤ 15 minutes

* JADAS-10 score-based definition for inactive disease:

* physician's global assessment of disease activity (NRS)

* parent/guardian's or patient's global assessment of overall wellbeing (NRS)

* number of joints (up to 10) with active arthritis

* CRP/ESR, whichever is available

Number of patients achieving clinical remissionEvery 3 months after index date until the end of follow-up or until secukinumab discontinuation or switching to another biologic, whichever occurs first, up to 5 years

Patients with 6 consecutive months of inactive disease are defined as entering clinical remission.

Summary of JIA ACR core components for all subjects and each JIA category.

Negative percent change indicates improvement.

JIA ACR criteria individual components:

* Number of joints with active arthritis

* Functional status using the Childhood Health Assessment Questionnaire (CHAQ) disability index and Health Assessment Questionnaire for adults.

* Physician global assessment of overall well-being through NRS.

* Parent/guardian's or patient's global assessment of overall well-being through NRS.

Change from baseline in JADAS-10 individual criteria:Baseline, up to 5 years

JADAS-10 stands for Juvenile Arthritis Disease Activity Score, with up to 10 joints assessed for active arthritis as part of the score. JADAS-10 individual criteria are:

* Physician's global assessment: NRS scale - 0 (inactive disease ) to 10 (active disease)

* Parent/guardian's or patient's global assessment: NRS scale - 0 (inactive disease ) to 10 (active disease)

* Number of joints with active arthritis: from 0 active joints to 10 active joints.

* CRP/ESR, whichever is available: Westergren erythrocyte sedimentation rate (ESR), normalized to a 0-10 scale. The CRP was truncated to a 0-10 scale accord¬ing to the following formula: (CRP (mg/l)-10)/10, similar to the normalized ESR used in the original JADAS.

Before calculation, CRP values \<10 mg/l were converted to 10 and CRP values \>110 mg/l were converted to 110.

JADAS-10 scoreAt baseline and every 3 months after index date until the end of follow-up or until secukinumab discontinuation or switching to another biologic, whichever occurs first, up to 5 years

JADAS-10 stands for Juvenile Arthritis Disease Activity Score, with up to 10 joints assessed for active arthritis as part of the score. The score spans from 0 to 40. Lower values mean lower activity and higher values mean higher activity.

The Enthesitis score using Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) asks for evaluation of swelling and tenderness at different anatomical locations.

All locations are scored as 0 "no activity" or 1 "activity". The MASES is the sum of all site scores.

Number of participants by JIA-related manifestationsAt baseline and every 3 months after index date until the end of follow-up or until secukinumab discontinuation or switching to another biologic, whichever occurs first, up to 5 years

JIA-related manifestations:

* Uveitis presence.

* General lymphadenopathy presence.

* Fever presence.

Modified Schoeber's test to assess axial mobility (ERA only).At baseline and every 3 months after index date until the end of follow-up or until secukinumab discontinuation or switching to another biologic, whichever occurs first, up to 5 years

Modified Schober's test is measuring lumbar spine mobility quantitatively. It measures lumbar spine flexion range of motion.

To conduct the test, the patient stands upright. The examiner locates the two posterior superior iliac spines and draws a horizontal line between them. A second point is marked 15cm above this line.Then the patient is asked to bend forwards as far as possible whilst keeping the knees fully extended. The distance between the previously marked points is measured again and indicates the amount of flexion.

Overall and nocturnal back pain NRS (ERA only).At baseline and every 3 months after index date until the end of follow-up or until secukinumab discontinuation or switching to another biologic, whichever occurs first, up to 5 years

For patients with Enthesitis-Related Arthritis (ERA), the overall and nocturnal back pain through NRS will be recorded. NRS stands for Numerical Rating Scale: 0 (no pain) to 10 (strongest pain).

Skin involvement using the Investigator Global Assessment Modified (IGA Mod) 2011 score (JPsA only).At baseline and every 3 months after index date until the end of follow-up or until secukinumab discontinuation or switching to another biologic, whichever occurs first, up to 5 years

The IGA Mod is a simple score for the evaluation of psoriasis:

0 = clear (e.g., no signs of psoriasis, some post-inflammatory hyperpigmentation may be present);

1. = almost clear (e.g., no thickening, normal or pink coloration);

2. = mild (e.g., mild thickening, pink to light red coloration),

3. = moderate (e.g., moderate thickening, dull to bright red);

4. = severe (e.g., severe thickening, bright to deep red).

Psoriasis Area Severity Index (PASI) (JPsA only).At baseline and every 3 months after index date until the end of follow-up or until secukinumab discontinuation or switching to another biologic, whichever occurs first, up to 5 years

For patients with Juvenile Psoriatic Arthritis (JPsA), the PASI score will be calculated. The PASI is used for assessing and grading the severity of psoriatic lesions and their response to therapy. PASI scores can range from a lower value of 0, corresponding to no signs of psoriasis, up to a theoretic maximum of 72.0.
