Malignancy-Related Ixekizumab Clinical Trial Criteria

  • Ixekizumab product labeling does not contain a contraindication for use in patients with a malignancy or history of malignancy.1 However, the use of ixekizumab in this population has not been studied.
  • Clinical Trial Exclusion Criteria:2-4
    • Active, or a history of malignant disease was an exclusion criterion in the pivotal psoriasis UNCOVER clinical trials (history of malignant disease within 5 years prior to baseline for SPIRIT-P2 and later trials, including IXORA psoriasis studies and SPIRIT-H2H in PsA).
    • Patients were excluded if they had current or a history of lymphoproliferative disease, or signs or symptoms of lymphoproliferative disease (limited to within 5 years of baseline for later trials).
    • Patients with successfully treated basal-cell carcinoma (no more than 3), squamous-cell carcinoma of the skin, or cervical carcinoma in situ, with no evidence of recurrence within the 5 years prior to baseline were allowed to participate in the pivotal psoriasis studies.
    • Note: This is not an all-inclusive list of exclusion criteria, but rather a list of those exclusion criteria related to malignancy.
  • Clinical Trial Discontinuation Criteria:2,4
    • The clinical trial protocols required patients who developed a malignancy to discontinue the studies.
    • Patients were allowed to continue if they developed no more than 2 NMSC over any 12-month period during the studies.
    • Note: This is not an all-inclusive list of discontinuation criteria, but rather discontinuation criteria related to malignancy.

Treatment-Emergent Lymphoma in Psoriasis Clinical Trials

  • Across 13 pooled psoriasis trials (N=5898, accounting for 17,003.4 PYs of total ixekizumab exposure as of September 2018 database lock), the IR of malignancies was 0.8 per 100 PYs of exposure.5
  • Treatment-emergent lymphomas reported in the 13 integrated psoriasis trial data cut described above based on MedDRA preferred terms were
    • B-cell lymphoma (n=2, 0.0%)
    • diffuse large B-cell lymphoma (n=1, 0.0%)
    • Hodgkin's disease (n=1, 0.0%) 
    • Hodgkin's disease mixed cellularity stage unspecified (n=1, 0.0%), and
    • Non-Hodgkin's lymphoma (n=1, 0.0%).4

Treatment-Emergent Lymphoma in Psoriatic Arthritis Clinical Trials

  • Across 3 pooled PsA trials (N=1118, accounting for 1937.7 PYs of total ixekizumab exposure as of September 2018 database lock), the IR of malignancies was 0.8 per 100 PYs of exposure.4
  • No treatment-emergent lymphomas were reported in the 3 integrated PsA trial data cut described above based on MedDRA preferred terms.4
