About this trial
This is an interventional treatment trial for Alpha-Mannosidosis
Eligibility 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
