Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • The subject must have participated in the phase 1 trial (EudraCT number: 2010-022084-36) and phase 2a trial (EudraCT number: 2010-022085-26)
  • Subject or subjects legally authorized guardian(s) must provide signed, informed consent prior to performing any trial-related activities (trial-related activities are any procedures that would not have been performed during normal management of the subject)
  • The subject and his/her guardian(s) must have the ability to comply with the protocol

Exclusion criteria

  • The subject cannot walk without support
  • Presence of known chromosomal abnormality and syndromes affecting psychomotor development, other than alpha-Mannosidosis
  • History of bone marrow transplantation
  • Presence of known clinically significant cardiovascular, hepatic, pulmonary or renal disease or other medical conditions that, in the opinion of the Investigator, would preclude participation in the trial
  • Any other medical condition or serious intercurrent illness, or extenuating circumstance that, in the opinion of the investigator, would preclude participation in the trial.
  • Pregnancy: Before the start of the treatment the investigators will decide whether or not there is a need for contraception. This assessment will be done through interviews with the patient and parents. The evaluation will be done continuously during the study
  • Psychosis within the last 3 months
  • Planned major surgery that, in the opinion of the investigator, would preclude participation in the trial
  • Participation in other interventional trials testing IMP except for studies with Lamazym
