One clinical trial evaluating the efficacy of an antibody neutralizing IL- 17A, AIN457, showed improvement of psoriasis in a subset of subjects (54 improvement in Psoriasis Area and Severity Index PASI over placebo) but demonstrated incomplete resolution of the clinical and pathological phenotype with a single dose of antibody (26). Accordingly, the pathogenic functions of cytokines contributed by Th1, Th17, and Th22 T-cell subsets in psoriasis vulgaris are still incompletely defined at present as is therapeutic mechanism of IL17 blockade in psoriasis. The clinical trial was conducted according to the principles expressed in the Declaration of Helsinki and informed consent for their information to be stored in the hospital database and used for research was obtained from all subjects in written form.

CONCLUSION: In patients with extensive psoriasis vulgaris treated once daily with Cal/BD foam for 4 weeks, we demonstrated no impact on the HPA axis and no clinically relevant effect on calcium homeostasis. 1University Hospitals Case Medical Center, Cleveland.

By adding Bagging procedure in each application, the stability and good predictive performance are warranted.

MSF is also partially supported by the Milstein Program in Medical Research. Psoriasis 3 classes genes selected by multi-TGDR after Bagging. We forwarded your question to senior author James Krueger, from The Rockefeller University in New York. Here is his response: While the phase 1 trial took place before the phase 2 trial and its clinical outcomes were known for the design of the phase 2 study, it took us a while in the laboratory to do more complex cellular and genomic measures in this study. Thus, it took some additional time to re-analyze our study results within the context of additional patients and samples.
