DNA REPOSITORY SUBSTUDY IN ASSOCIATION WITH XOLAIR (OMALIZUMAB) STUDY Q4881g
Date : 24 September 2010
Version 1
The primary objective of this study is to perform exploratory analyses to generate hypotheses identifying genes associated with treatment response, toxicity, or disease risk. If such genetic hypotheses are identified, they may be tested in future clinical studies within this therapeutic area. |

16. Presence of clinically significant cardiovascular, neurological, psychiatric,
metabolic or other pathological conditions that could interfere with the
interpretation of the study results and or compromise the safety of the patients.

decompensation of co-existing conditions for the duration of the study.
Any items that are cause for uncertainty must be reviewed with the Medical Monitor.
18. Inability to comply with study and follow-up procedures.
19. Evidence of current drug or alcohol abuse.

| E.5 End points |
| E.5.1 | Primary end point(s) |
| The primary efficacy endpoint is the change in weekly itch score from baseline to Week 12. The analysis of the primary endpoint will consist of treatment comparisons made using analysis of covariance (ANCOVA) controlling for baseline weekly itch score, and baseline weight (less than 80 kg vs. more than or equal to 80 kg). The ANCOVA model will be based on the mITT patients. Missing Week 12 itch scores will be imputed by carrying forward the patients’ baseline scores (BOCF). The Week 12 itch scores for patients who received excluded therapy listed in Section 4.4.2 by Week 12 will also be imputed using their baseline scores. |
