“Exploratory Pharmacogenomics Assessment Substudy", version 1.0, dated 27Feb2018 A pharmacogenomics (PGx) substudy will be conducted for exploratory analysis of genetic variations predictive of autoimmune conditions, including thyroid and immune thrombocytopenia (ITP), related to MS disease and/or the effects of alemtuzumab. For research purposes only and on a voluntary basis, a blood sample will be proposed to approximately 300 ongoing patients in the TOPAZ study who have not provided a PGx sample in the previous studies (CAMMS03409, CAMMS223, CAMMS323 and CAMMS324). A blood sample will be collected from consenting patients.  Objectives of the substudy are as follows: • To develop biomarkers predictive of autoimmune conditions including thyroid disorders and immune thrombocytopenia. This will include collection of samples from patients who have not yet developed any auto immune conditions; these samples would be used as controls. • To explore efficacy and safety markers through data analysis. • To explore genetic variation related to MS disease manifestation through data analysis. Sample collection, handling, storage, and analysis will conform to all applicable national guidance and regulations. |
