1.1 Adalimumab, certolizumab pegol, etanercept, golimumab and infliximab are recommended, within their marketing authorisations, as options for treating severe active ankylosing spondylitis in adults whose disease has responded inadequately to, or who cannot tolerate, non‑steroidal anti‑inflammatory drugs. Infliximab is recommended only if treatment is started with the least expensive infliximab product. People currently receiving infliximab should be able to continue treatment with the same infliximab product until they and their NHS clinician consider it appropriate to stop.

1.2 Adalimumab, certolizumab pegol and etanercept are recommended, within their marketing authorisations, as options for treating severe non‑radiographic axial spondyloarthritis in adults whose disease has responded inadequately to, or who cannot tolerate, non‑steroidal anti‑inflammatory drugs.

1.3 The choice of treatment should be made after discussion between the clinician and the patient about the advantages and disadvantages of the treatments available. This may include considering associated conditions such as extra‑articular manifestations. If more than 1 treatment is suitable, the least expensive (taking into account administration costs and patient access schemes) should be chosen.

1.4 The response to adalimumab, certolizumab pegol, etanercept, golimumab or infliximab treatment should be assessed 12 weeks after the start of treatment. Treatment should only be continued if there is clear evidence of response, defined as:

  • a reduction in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score to 50% of the pre‑treatment value or by 2 or more units and

  • a reduction in the spinal pain visual analogue scale (VAS) by 2 cm or more.

1.5 Treatment with another tumour necrosis factor (TNF) ‑alpha inhibitor is recommended for people who cannot tolerate, or whose disease has not responded to, treatment with the first TNF‑alpha inhibitor, or whose disease has stopped responding after an initial response.

1.6 When using BASDAI and spinal pain VAS scores, healthcare professionals should take into account any physical, sensory or learning disabilities, or communication difficulties that could affect the responses to the questionnaires, and make any adjustments they consider appropriate.
