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
Therapeutic
Indications
Ixekizumab
is indicated for the treatment of moderate to severe plaque psoriasis
in adults who are candidates for systemic therapy.1
Ixekizumab,
alone or in combination with methotrexate, is indicated for the
treatment of active psoriatic arthritis in adult patients who have
responded inadequately to, or who are intolerant to one or more
disease-modifying anti-rheumatic drug (DMARD) therapies.1
