Routine Laboratory Monitoring
Treatment with ixekizumab does not have a requirement for routine laboratory monitoring.
Patients who are being treated with biologic therapy should be monitored regularly according to current standard-of-care recommendations. Appropriate symptomatic treatment of adverse reactions should also be implemented under the direction of the prescribing physician.
Monitoring of Infections, Tuberculosis, and Inflammatory bowel disease in General
Ixekizumab should be used with caution in patients with clinically important chronic infection or a history of recurrent infection. 1
Patients should be instructed to seek medical advice if signs or symptoms suggestive of an infection occur.1
If an infection develops,
- patients should be carefully monitored and
- ixekizumab discontinued if
- the patient is not responding to standard therapy or if
- the infection becomes serious.1
Ixekizumab should not be resumed until the infection resolves.1
Patients receiving ixekizumab should be monitored closely for signs and symptoms of active TB during and after treatment.2 Ixekizumab is contraindicated in patients with clinically important active infections (e.g. active tuberculosis). Consider anti-TB therapy prior to initiation of ixekizumab in patients with latent TB.1
Cases of new or exacerbations of inflammatory bowel disease have been reported with ixekizumab. Ixekizumab is not recommended in patients with inflammatory bowel disease.1
If a patient develops signs and symptoms of inflammatory bowel disease or experiences an exacerbation of pre-existing inflammatory bowel disease, ixekizumab should be discontinued and appropriate medical management should be initiated.1
The most recent guidelines from the American Academy of Dermatology and National Psoriasis Foundation provide expert consensus on treatment with biologics and the supplemental information for IL-17 inhibitors suggest
- general screening (complete blood count, complete metabolic panel, and chest radiograph for positive TB)
- pretreatment test for latent TB
- serologic tests for hepatitis B and C
- pre-treatment test for HIV at the practitioner's discretion
- pre-treatment evaluation for history of IBD
- yearly testing for latent TB in high risk patients, and
- periodic history and physical examination at follow-up visits.3
The most recent guidelines from the American Academy of Dermatology and National Psoriasis Foundation provide expert consensus on treatment of pediatric patients with psoriasis and suggest that laboratory monitoring for children receiving biologic therapy should be individualized based on the clinical context for each patient including the potential presence of comorbidities and risk factors.4
In addition to the above recommendations, the American College of Rheumatology and the National Psoriasis Foundation have suggested that the healthcare provider may want to consider markers of inflammation, such as CRP and ESR, and imaging results to determine if the patient has active PsA.5
The frequency of monitoring should be individualized based on the patient's particular disease course.6
The American College of Rheumatology has suggested that periodic monitoring of CRP or ESR may be helpful to guide treatment, particularly in patients with active symptoms of AS/r-axSpA or nr-axSpA.7
In 3 phase 3 studies of ixekizumab for the treatment of axSpA (including AS/r-axSpA and nr-axSpA), patients were monitored for neutropenia, abnormal liver function tests, hepatitis B DNA, and hypertension.2
Patients receiving ixekizumab should be monitored closely for signs and symptoms of active TB during and after treatment.2
