Exclusion Criteria
- Is pregnant or breastfeeding, at Baseline, or planning to become pregnant (self or partner) at any time during the study.
- Has used any investigational product (other than BMN 110 in MOR-004), or investigational medical device, within 30 days prior to Baseline; or is required to use any investigational agent prior to completion of all scheduled study assessments.
- Was enrolled in a previous BMN 110 study, other than MOR-004.
- Has a concurrent disease or condition, including but not limited to, symptomatic cervical spine instability, clinically significant spinal cord compression, or severe cardiac disease that would interfere with study participation, or pose a safety risk, as determined by the Investigator.
