E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To evaluate the efficacy of guselkumab for the treatment of subjects with moderate to severe plaque-type psoriasis. • To assess the safety and tolerability of guselkumab in subjects with moderate to severe plaque-type psoriasis.
|
|
E.2.2 | Secondary objectives of the trial |
• To compare the efficacy of guselkumab to adalimumab in subjects with moderate to severe plaque type psoriasis. • To evaluate the effect of treatment with guselkumab on other measures of signs and symptoms of psoriasis. • To evaluate the effect of treatment with guselkumab on health-related quality of life. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Skin biopsy samples will be collected from a subset of subjects who consent to participate in the optional biopsy substudy. Enrollment in the biopsy substudy will be optional and will include approximately 90 subjects at selected sites. Only subjects who consent to participate in the optional biopsy substudy will undergo collection of these samples. Biopsies will be used for assessment of RNA expression. Protocol A1, dated 12 February 2015 |
