Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

* Parent(s) or guardian(s) are willing and able to provide written, signed informed consent after the nature of the study has been explained and prior to performance of any research-related procedure. Also, subjects under the age of majority are willing and able to provide written assent (if required by local regulations or the IRB/IEC) after the nature of the study has been explained and prior to performance of any research-related procedure. Subjects who reach the age of majority in their country while the study is ongoing will be asked to provide their own written consent again upon reaching the legal age of majority.

* Permanently discontinued BMN 111 or placebo prior to completion of the 111-301 study
* Have a clinically significant finding or arrhythmia on Baseline ECG that indicates abnormal cardiac function
* Evidence of decreased growth velocity (\<1.5 cm/year) as assessed over a period of at least 6 months or of growth plate closure (proximal tibia, distal femur) through bilateral lower extremity X-rays.
* Require any investigational agent prior to completion of study period
* Current therapy with medications known to alter renal function
* Pregnant or breastfeeding or plan to become pregnant during study
* Concurrent disease or condition that, in the view of the investigator, would interfere with study participation or safety evaluations, for any reason.
