Medical Necessity and Standard of Care Assessment for Ankylosing Spondylitis Treatment
Direct Recommendation
The treatment plan is medically necessary and represents standard of care for active ankylosing spondylitis with inadequate response to current therapy, though several components require modification based on current guidelines. 1
Medical Necessity Analysis
Golimumab Continuation is Appropriate
- Continuation of golimumab is medically necessary and strongly supported by guidelines, as the ACR conditionally recommends against discontinuation of biologics in patients receiving treatment, since discontinuation leads to disease flares in 60-74% of patients 1, 2
- The patient demonstrates partial improvement, which represents effective disease control in this chronic progressive condition—maintaining current disease activity while on therapy prevents progression and should not be confused with treatment failure 2
- The ACR guidelines explicitly state that continuation of biologic therapy is appropriate when patients achieve or maintain a positive clinical response, including low disease activity 2
- Golimumab has demonstrated sustained efficacy through 104 weeks in clinical trials, with ASAS20 response rates of 60-71% and acceptable safety profiles 3
Problematic Components of the Treatment Plan
The use of systemic prednisone contradicts guideline recommendations and indicates inadequate disease control. The ACR strongly recommends against treatment with systemic glucocorticoids in ankylosing spondylitis 1. The need for prednisone suggests the current golimumab regimen is insufficient 2.
Hydroxychloroquine is not supported by evidence for axial ankylosing spondylitis. Conventional synthetic DMARDs (including hydroxychloroquine) have limited efficacy for axial disease, though they may be considered for peripheral arthritis 4. The ACR conditionally recommends against adding conventional DMARDs in favor of biologic optimization 2.
Standard of Care Assessment
What IS Standard of Care
- TNF inhibitor therapy (including golimumab) is strongly recommended by the ACR for active ankylosing spondylitis despite NSAID therapy, with high-quality evidence 1, 2
- Diclofenac sodium is FDA-approved and evidence-based for ankylosing spondylitis, with studies demonstrating efficacy at 100-125 mg/day using a q.i.d. dosing regimen 5, 6
- Folic acid supplementation is appropriate when used with methotrexate or other folate antagonists, though its necessity in this specific regimen depends on whether the patient is on methotrexate
- NSAIDs remain first-line therapy and are strongly recommended for managing pain and stiffness in ankylosing spondylitis 1, 4
Treatment Optimization Needed
For patients with secondary non-response to golimumab (ongoing symptoms despite initial improvement), the ACR conditionally recommends switching to a different TNF inhibitor over switching to a non-TNF biologic 2, 4. Alternative options include:
- Switching to another TNF inhibitor (infliximab, adalimumab, certolizumab, etanercept) 1, 4
- Switching to IL-17 inhibitors (secukinumab or ixekizumab) if this represents primary non-response 1, 2
The ACR conditionally recommends continuing TNF inhibitor alone over continuing both TNF inhibitor and conventional synthetic DMARDs 1, suggesting hydroxychloroquine should be discontinued 2.
Critical Clinical Pitfalls
- Do not discontinue golimumab based solely on partial response—the ACR conditionally recommends against discontinuation as a standard approach 1, 2
- Avoid long-term systemic glucocorticoids—the strong recommendation against systemic steroids in AS means prednisone should be tapered and discontinued 1
- Do not add conventional DMARDs to inadequately controlled disease on TNF inhibitors—instead, optimize biologic therapy by switching to a different TNF inhibitor or IL-17 inhibitor 1, 2
- Local glucocorticoid injections are conditionally recommended for isolated enthesitis or peripheral arthritis despite NSAIDs, but systemic steroids are not 1
Experimental vs. Standard Designation
This treatment plan is NOT experimental or investigational. All components are FDA-approved for their respective indications:
- Golimumab is FDA-approved for ankylosing spondylitis at 50 mg subcutaneously every 4 weeks 7, 3
- Diclofenac sodium is FDA-approved for ankylosing spondylitis at 100-125 mg/day 5
- However, the combination approach and specific medication choices (particularly hydroxychloroquine and prednisone) deviate from evidence-based guidelines 1, 2
Recommended Treatment Algorithm
For this patient with active disease despite golimumab:
- Continue golimumab while optimizing other therapies 1, 2
- Taper and discontinue prednisone as it contradicts guidelines 1
- Discontinue hydroxychloroquine unless specifically treating peripheral arthritis, as the ACR recommends TNF inhibitor monotherapy 1
- Optimize diclofenac dosing to 100-125 mg/day per FDA labeling for ankylosing spondylitis 5
- If inadequate response persists after optimization, switch to a different TNF inhibitor rather than adding conventional DMARDs 1, 2
- Consider local glucocorticoid injections for specific enthesitis sites rather than systemic steroids 1
- Ensure physical therapy is incorporated, as it is strongly recommended by the ACR 1
