Who this trial is looking for
This trial is looking for children with juvenile idiopathic arthritis. Participants will help doctors understand how to choose the best treatments for their arthritis.
Are You a Good Fit for This Trial?
You may be able to join if
I am 18 years old or younger.
I have active arthritis or have been diagnosed with arthritis in the last 6 months.
I have not started any treatment besides NSAIDs.
I have a confirmed diagnosis of juvenile idiopathic arthritis.
I am experiencing active arthritis.
I have inactive disease and need to stop or reduce my biologic treatment.
I have severe disease that is hard to control with treatment.
You may not be able to join if
My arthritis is caused by another diagnosis.
I have had joint injections within the last 4 weeks.
I have arthritis that is explained by another cause.
I am starting biologic treatment only for uveitis.
I have an ongoing tapering scheme for biologics that will take more than 12 months.

Childhood arthritis is a chronic disabling disease. New medications called biologic therapies are now available to treat arthritis that target key biologic molecules that cause inflammation. Biologic therapies, while very effective in treating arthritis in children, may have serious side effects including infections and potentially cancers, and are very expensive and doctors don't know, which one …
Childhood arthritis is a chronic disabling disease. New medications called biologic therapies are now available to treat arthritis that target key biologic molecules that cause inflammation. Biologic therapies, while very effective in treating arthritis in children, may have serious side effects including infections and potentially cancers, and are very expensive and doctors don't know, which one to choose for which child. The investigators will develop tests that enable them to learn about the biology of each child's arthritis and be able to predict when and which biologic therapy to start and when to stop.

Inclusion Criteria:
Cohort 1: - Biologic Basis of JIA
* ≤18 years\*
* Active objective arthritis suspected to be JIA or diagnosed with JIA within 6 months of enrolment
* Treatment naïve except for NSAIDs, allowed to have received NSAIDS within 6 months of diagnosis
Cohort 2 - Start Biologics
* JIA diagnosis as per ILAR criteria (all subtypes)
* ≤18 years\*
* Active arthritis
* For sJIA, active disease not necessarily with arthritis.
* Time of start, restart or switch biologic therapy: e.g. failure, insufficient/partial response or intolerance
Cohort 3 - Stop Biologics
* JIA diagnosis as per ILAR criteria (all subtypes)
* ≤18 years\*
* Inactive disease
* Discontinuing/tapering biologics for inactive disease
Cohort 4: Extreme Phenotypes
* Unexplained systemic inflammation with arthritis/arthralgia as a part of manifestations
* High suspicion of genetic contribution
* Severely affected patients with difficult to control disease (ie failure of multiple biologics)
Exclusion Criteria:
Cohort 1 :
* Arthritis explained by another diagnosis
* Joint injections as previous treatment less than 4 weeks prior to enrollment
Cohort 2:
* Arthritis explained by any other cause
* Start on biologics as an indication for uveitis only
Cohort 3:
\- Tapering scheme \> 12 months to complete biologics stop
Cohort 4:
\- Arthritis explained by another diagnosis
