Psoriasis Clinical Trial
Official title:
An Investigator-Initiated, Assessor Blinded, Randomized Study Comparing the Mechanism of Action of Adalimumab to Methotrexate in Subjects With Moderate to Severe Chronic Plaque Psoriasis.
The objective of this study is to compare the mechanism of action between adalimumab and methotrexate in subjects with psoriasis.
Both methotrexate and adalimumab are FDA-approved drugs for the treatment of moderate to
severe psoriasis. The two treatments, methotrexate and adalimumab, both show efficacy for
psoriasis, however their profiles differ. In the CHAMPION Study, more adalimumab-treated,
moderate to severe psoriasis patients achieved a PASI 75 after 16 weeks compared to those
treated with methotrexate (80% vs. 36%). The reason for this difference is poorly
understood. No direct comparative mechanism of action studies in psoriasis patients between
methotrexate and adalimumab (or any tumor necrosis factor blocker) has been reported.
With etanercept, another tumor necrosis factor blocker, the in vivo mechanism has been
studied with some scientific rigor. These studies demonstrate that etanercept down regulates
multiple pro-inflammatory pathways (as shown in Table 1 of the protocol).
To date, there are no similar studies with adalimumab or methotrexate.
In order to understand the molecular and cellular basis for the differential clinical
efficacy of adalimumab and methotrexate, it is essential to compare their mechanisms of
action in psoriatic plaques. Biopsies will be performed, and we will study biomarkers in
this proposal with immunohistochemistry, real-time polymerase chain reaction, and gene
arrays.
