Eligibility Criteria

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

Inclusion Criteria

* Subject or subjects legally authorized guardian(s) must provide signed, informed consent prior to performing any trial-related activities
* The subject and his/her guardian(s) must have the ability to comply with the protocol
* The subject must have a confirmed diagnosis of alpha-Mannosidosis as defined by alpha-Mannosidase activity \< 10% of normal activity (historical data)
* The subject must have an age at the time of screening ≥ 5 years and ≤ 35 years
* The subject must have the ability to physically and mentally cooperate in the tests
* The subject must have an ECHO without abnormalities that, in the opinion of the Investigator, would preclude participation in the trial

Exclusion Criteria

* The subjects diagnosis cannot be confirmed by alpha-Mannosidase activity \< 10% of normal activity
* The subject cannot walk without support
* Presence of known chromosomal abnormality and syndromes affecting psychomotor development, other than alpha-Mannosidosis
* History of BMT
* 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: Pregnant woman is excluded. Before start of the treatment the investigators will for women of childbearing potential perform a pregnancy test and decide whether or not there is a need for contraception
* Planned major surgery that, in the opinion of the Investigator, would preclude participation in the trial
* Participation in other interventional trials testing IMP (including Lamazym) within the last 3 months
* Adult patients who, in the opinion of the Investigator, would be unable to give consent, and who does not have any legal protection or guardianship
* Total IgE \>800 IU/ml
* Known allergy to the IMP or any excipients (Sodium-Phosphate, Glycine, Mannitol)
