Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To identify new candidate genes that are differentially expressed in responders’ vs non-responders to anti-TNF alpha therapy at the several time points we will use the transcriptomic and proteomic analyses; Secondary Objective: 1) QoL evaluation 2) MRI progression under TNF-alpha therapy ;Primary end point(s): To identify new candidate genes that are differentially expressed in responders’ vs non-responders to anti-TNF alpha therapy at the several time points we will use the transcriptomic and proteomic analyses;Timepoint(s) of evaluation of this end point: Response at 14 weeks will be compared with genetic profile. | — |
