This is a multi-center, open-label, single-arm safety extension study. After completing 12 months of treatment with LMIS 50 mg under Protocol FP01C-13-001 (with last dose under Protocol FP01C-13-001 approximately 6 months prior to Day 0 or Protocol FP01C-13-001-EX) and providing a written informed consent, subjects will be screened against baseline inclusion/exclusion criteria necessary for study eligibility. Eligible subjects will receive LMIS 50 mg from the prefilled syringes (without dilution or other mixing) in up to two single subcutaneous injections given 6 months apart.
