2. Subjects with any significant change in medical history, including laboratory tests, or a current clinically significant condition that in the opinion of the Investigator would have excluded the subject from participation in Study 105MS301. The Investigator must re-review the subject’s medical fitness for participation and consider any factors that would preclude treatment including:
• Presence of any clinically significant (as determined by the Investigator) cardiac,
endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary,
neurologic, dermatologic, psychiatric, renal, or other major disease that would preclude participation in a clinical study.
• Presence of malignant disease, including solid tumors and hematologic malignancies (with the exception of basal cell and squamous cell carcinomas of the skin that have been completely excised and are considered cured).
• Clinically significant laboratory abnormalities (hematology and blood chemistry) on
the most recently available test of Study 105MS301, as determined by the Investigator. Laboratory findings mandating discontinuation of study treatment as defined in protocol 105MS301 are exclusionary.
3. Female subjects who are currently pregnant (as reflected by a positive pregnancy test at the Week 96 Visit of Study 105MS301/Baseline Visit), who are currently breastfeeding, or who are considering becoming pregnant while in the study.
