Ixekizumab for treating moderate to severe plaque psoriasis - NICE TAG TA442

1.1 Ixekizumab is recommended as an option for treating plaque psoriasis in adults, only if:

• the disease is severe, as defined by a total Psoriasis Area and Severity Index (PASI) of 10 or more and a Dermatology Life Quality Index (DLQI) of more than 10

• the disease has not responded to standard systemic therapies, for example, ciclosporin, methotrexate and PUVA (psoralen and long-wave ultraviolet radiation), or these treatments are contraindicated or the person cannot tolerate them, and

• the company provides the drug with the discount agreed in the patient access scheme.

1.2 Stop ixekizumab treatment at 12 weeks if the psoriasis has not responded adequately. An adequate response is defined as:

• a 75% reduction in the PASI score (PASI 75) from when treatment started or

• a 50% reduction in the PASI score (PASI 50) and a 5‑point reduction in DLQI from when treatment started.

1.3 When using the PASI, healthcare professionals should take into account skin colour and how this could affect the PASI score, and make the clinical adjustments they consider appropriate.

1.4 When using the DLQI, healthcare professionals should take into account any physical, psychological, sensory or learning disabilities, or communication difficulties, that could affect the responses to the DLQI and make any adjustments they consider appropriate.

1.5 These recommendations are not intended to affect treatment with ixekizumab that was started in the NHS before this guidance was published. People having treatment outside these recommendations may continue without change to the funding arrangements in place for them before this guidance was published, until they and their NHS clinician consider it appropriate to stop.
