Reimbursement Recommendation

Tofacitinib

Reimbursement request: For the treatment of active polyarticular juvenile idiopathic arthritis (pJIA; rheumatoid factor positive [RF-positive] or rheumatoid factor negative [RF-negative] polyarthritis, extended oligoarthritis, and systemic JIA [sJIA] without active systemic manifestations), juvenile psoriatic arthritis (JPsA), and enthesitis-related arthritis (ERA) in children who have responded inadequately or are intolerant to tumour necrosis factor (TNF) inhibitors or when use of those therapies is inadvisable.

Requester: Public drug programs

Final recommendation: Reimburse with conditions

Summary

What Is the Reimbursement Recommendation for Tofacitinib?

The Formulary Management Expert Committee (FMEC) recommends that tofacitinib be reimbursed for the treatment of patients with juvenile idiopathic arthritis (JIA) provided certain conditions are met.

What Are the Conditions for Reimbursement?

Tofacitinib may be initiated for pediatric patients (between the age of 2 and below 18 years) for the treatment of JIA if all the following conditions are met. The patient must have a confirmed diagnosis of JIA, which includes the following subtypes: polyarticular course juvenile idiopathic arthritis (rheumatoid factor [RF]–positive polyarthritis, RF-negative polyarthritis, extended oligoarthritis, and systemic JIA without active systemic features), psoriatic arthritis, and enthesitis-related arthritis. The patient must also meet at least 1 of the following conditions related to methotrexate therapy: they have an inadequate response to methotrexate monotherapy at a maximum tolerated dose for at least 3 months; they have developed an intolerance to, or have a contraindication to, methotrexate therapy; or methotrexate is clinically inappropriate for the treatment of the patient’s condition. In addition, the patient must have had an inadequate response to a tumour necrosis factor (TNF) inhibitor or TNF inhibitor use is clinically inappropriate for the patient. Tofacitinib must also represent good value to the drug plans.

Why Did CDA-AMC Make This Recommendation?

FMEC reviewed the Canada’s Drug Agency (CDA-AMC) report, which included the PROPEL trial that compared tofacitinib to placebo in patients with polyarticular course JIA, 1 long-term extension study, 1 indirect treatment comparison, and a cost comparison of tofacitinib versus other treatments used in Canada. The PROPEL trial results suggest a difference between treatments, with tofacitinib showing a greater improvement in JIA flare rate by week 44, and a greater improvement of JIA American College of Rheumatology (ACR) 30% (ACR30), 50% (ACR50), and 70% (ACR70) responses at week 44 for patients with polyarticular course JIA relative to placebo.

FMEC also considered input received from Arthritis Consumer Experts; a joint submission from Arthritis Society Canada, Canadian Arthritis Patient Alliance, Canadian Spondyloarthritis Association, Cassie + Friends, and Psoriasis Canada; the Canadian Rheumatology Association; and public drug programs.

FMEC concluded that there was uncertainty in the clinical value demonstrated by tofacitinib and there is a significant clinical need arising from JIA despite available treatments. The reimbursement conditions were further developed based on distinct social and ethical considerations, economic considerations, and impacts on the health system.

Therapeutic Landscape

What Is JIA?

JIA is a chronic inflammatory disorder primarily involving the joints, with persistent joint swelling that can cause degradation of the articular cartilage and deformities of affected joints. JIA can be associated with concomitant uveitis (inflammation of the eyes) that can result in visual impairment, glaucoma, band keratopathy, and cataracts. Patients living with JIA experience physical challenges that negatively affect their mental health and their ability to participate in school, work, and activities of daily living and recreation. In fiscal year 2022–2023, it was estimated that 6,545 children aged from birth to 15 years were living with JIA in Canada and 865 children in this age group were newly diagnosed with JIA.

What Are the Current Treatment Options?

To manage JIA, treatments such as conventional synthetic disease-modifying antirheumatic drugs (DMARDs) (e.g., methotrexate) and/or biologic DMARDs (e.g., TNF inhibitors, abatacept, and tocilizumab) are necessary. Targeted synthetic DMARDs (e.g., Janus kinase [JAK] inhibitors: tofacitinib) are emerging therapies, especially for individuals with JIA whose disease has lacked a response or had an inadequate response to other therapies. Nonsteroidal anti-inflammatory drugs (NSAIDs) are mainly used to treat axial disease associated with psoriatic arthritis (with spinal involvement and common symptoms such as back pain) and as bridging therapy while awaiting the onset of treatment effects with a DMARD. Systemic glucocorticoids are primarily used in patients with severe systemic inflammation or severe debilitating polyarticular disease without fair symptomatic relief or control with NSAIDs.

What Is the Treatment Under Review?

Tofacitinib is a targeted synthetic DMARD and a potent selective inhibitor of the JAK family of kinases, particularly JAK1 and JAK3. Tofacitinib treats inflammation in autoimmune disease, including inflammatory arthritis such as JIA. The current review of tofacitinib encompasses both the Health Canada–approved indication for the treatment of children with active polyarticular JIA (RF-positive or RF-negative polyarthritis, extended oligoarthritis, and systemic JIA without systemic manifestations), psoriatic arthritis, and as an off-label indication for the treatment of children with enthesitis-related arthritis.

Why Did We Conduct This Review?

Following clinicians’ interest in accessing tofacitinib for the treatment of JIA, the public drug programs requested a nonsponsored review be conducted to inform a reimbursement recommendation for tofacitinib for the treatment of active polyarticular JIA (RF-positive or RF-negative polyarthritis, extended oligoarthritis, and systemic arthritis without systemic manifestations), juvenile psoriatic arthritis, and enthesitis-related arthritis in children who have responded inadequately or are intolerant to TNF inhibitors or when use of those therapies is inadvisable. Tofacitinib offers a novel mechanism of action and is available as an oral tablet. Tofacitinib could potentially fulfill an unmet need in the pediatric population.

Data protection for tofacitinib expired on October 17, 2022, and several generics are already approved and available in Canada. Because tofacitinib is a drug that is later in its life cycle, it is eligible for a nonsponsored reimbursement review as per the Procedures for Reimbursement Reviews.

Person With Lived Experience

A graduate student from Ontario shared her journey with JIA, spotlighting her experience living with JIA as an adolescent. Issues in multiple joints made walking, sleeping, and activities of daily living difficult. A diagnosis was a relief when it finally came in her mid-teens. She worried about potential treatment side effects, such as hair loss. She trialled various drugs, including several TNF inhibitors, before starting tofacitinib, which she received through a patient assistance program. She found tofacitinib effective, tolerable, and easy to take. A significant benefit was the freedom a once-daily oral medication offered compared to injections and infusions. She received help from her mother to manage her condition and from some accommodations at school, but she noted a general lack of support for people with JIA. She emphasized the importance of the patient voice in matters of access and care.

Reason

        Implementation guidance

Initiation

1. Tofacitinib may be initiated for pediatric patients (between the age of 2 and below 18 years) for the treatment of JIA if all the following conditions are met:

1.1. The patient has a confirmed diagnosis of JIA, including any of the following subtypes:

1.1.1. polyarticular course juvenile idiopathic arthritis (RF-positive polyarthritis, RF-negative polyarthritis, extended oligoarthritis, and systemic JIA without active systemic features)

1.1.2. psoriatic arthritis

1.1.3. enthesitis-related arthritis.

1.2. At least 1 of the following conditions related to methotrexate therapy is met:

1.2.1. the patient has an inadequate response to methotrexate monotherapy at a maximum tolerated dose for at least 3 months

1.2.2. the patient has developed an intolerance to, or has a contraindication to, methotrexate therapy

1.2.3. methotrexate is clinically inappropriate for the treatment of the patient’s condition.

1.3. The patient has an inadequate response to a TNF inhibitor or if TNF inhibitor use is clinically inappropriate.

In the PROPEL trial, treatment with tofacitinib signalled clinical benefit in patients aged 2 years to younger than 18 years with polyarticular course JIA (RF-positive and RF-negative polyarthritis, extended arthritis, and systemic JIA without systemic features), psoriatic arthritis, and enthesitis-related arthritis.

The PROPEL trial included a mixed population of participants with and without prior TNF inhibitor experience. The majority of the enrolled population had not previously been treated with a TNF inhibitor. The reason for TNF inhibitor discontinuation in the group with TNF inhibitor experience was not reported.

The PROPEL trial enrolled patients who met the International League of Associations for Rheumatology classification criteria.a However, based on discussion with the guest specialists, the treatment landscape is evolving, and these classifications (e.g., those based on number of joint counts with active disease) may not align with current clinical practice and could inadvertently restrict treatment with tofacitinib in patients for whom it may be clinically appropriate.

For implementation, jurisdictions may consider using the existing criteria for JIA.

Based on consultation with guest specialists, initiating treatment with methotrexate in patients with psoriatic arthritis or enthesitis-related arthritis may not be clinically appropriate. For example, patients with axial disease or with spinal involvement may receive NSAIDs as first-line treatment. The guest specialists also noted that conventional DMARDs (e.g., methotrexate) have not consistently shown benefit in these patients.

In the PROPEL trial, patients with polyarticular course JIA had to have an inadequate response to 1 or more DMARDs (methotrexate or biological DMARDs). For patients with psoriatic arthritis or enthesitis-related arthritis, they had to have an inadequate response to NSAIDs.

Maintenance and renewal

2. Tofacitinib should be continued if there is objective evidence of improvement after 6 months.

Consistent with clinical practice, patients may continue therapy based on routine assessment of responses by a specialist.

Jurisdictions may implement maintenance and renewal criteria to align with their existing guidelines or policies.

Prescribing

3. Prescribing should be limited to clinicians with expertise in the diagnosis and management of JIA.

This will ensure that treatment is prescribed for patients for whom it is clinically appropriate and that adverse events are optimally managed.

Pricing

4. Tofacitinib must represent good value to the drug plans.

Tofacitinib is associated with lower drug acquisition costs at publicly available prices vs. all comparators.

Based on the available network meta-analysis, it is uncertain whether tofacitinib provides a clinically important advantage or disadvantage compared with any included comparator.

Ensuring that the cost of tofacitinib does not exceed the per-patient drug plan cost of the least costly therapy for this population would reduce the uncertainty that tofacitinib would provide good value to drug plans.

DMARD = disease-modifying antirheumatic drug; JIA = juvenile idiopathic arthritis; NSAID = nonsteroidal anti-inflammatory drug; RF = rheumatoid factor; TNF = tumour necrosis factor.

Special thanks: CDA-AMC extends our special thanks to the individuals who presented directly to FMEC and to the patient organizations representing and supporting the community of those living with JIA, including the Canadian Arthritis Patient Alliance, Laurie Proulx, and Naomi Abrahams.

Note: CDA-AMC makes every attempt to engage with people with lived experience as closely to the indication and treatments under review as possible; however, at times, CDA-AMC is unable to do so and instead engages with individuals with similar treatment journeys or experience with comparators under review to ensure lived experience perspectives are included and considered in Reimbursement Reviews. CDA-AMC is fortunate to be able to engage with individuals who are willing to share their treatment journey with FMEC.
