Primary Outcome Measures:
  • Reduction of Oligosaccharides in blood serum [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Efficacy endpoint evaluation as change from baseline


Secondary Outcome Measures:
  • The number of steps climbed in 3 minutes (3-minute stair climb) [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Efficacy endpoint evaluation as change from baseline

  • Reduction of Oligosaccharides in CSF [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Efficacy endpoint evaluation as change from baseline

  • The distance walked in 6 minutes (6-minute walk test) [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Efficacy endpoint evaluation as change from baseline

  • Pulmonary function [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Efficacy endpoint evaluation as change from baseline

  • Adverse events [ Time Frame: 1 week ] [ Designated as safety issue: Yes ]
    Safety endpoint assesed weekly throughout the trial

  • Development of clinically significant changes in vital signs and change in physical examination [ Time Frame: 1 week ] [ Designated as safety issue: Yes ]
    Safety endpoint assesed weekly throughout the trial

  • Development of clinically significant changes in the clinical laboratory parameters (hematology, biochemistry and urinalysis) [ Time Frame: 1 week ] [ Designated as safety issue: Yes ]
    Safety endpoint assesed weekly throughout the trial

  • Development of rhLAMAN antibodies and neutralizing/inhibitory antibodies [ Time Frame: 1 week ] [ Designated as safety issue: Yes ]
    Safety endpoint assesed weekly throughout the trial

  Eligibility

Ages Eligible for Study:   5 Years to 21 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

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
