| Main Objective: • Define effective dose based on evaluation of efficacy of rhLAMAN (Lamazym) from baseline on: The biochemical markers , The clinical parameters • To evaluate the long-term safety profile of rhLAMAN (Lamazym) ;Secondary Objective: • To determine the PK profile after repeated dose of rhLAMAN (Lamazym) in patients with alpha-Mannosidosis as measured by rhLAMAN levels in plasma ;Primary end point(s): Efficacy endpoints, measured at interim (3 months) and 6 months evaluation: Change from baseline of Oligosaccharide in serum-, urine- and cerebrospinal fluid Change from baseline in cerebrospinal fluid neurodegeneration biomarkers Change from baseline of MRS (white matter and mannose level) Change from baseline of functional capacity (6MWT, 3MSC, BOT2, Gait) Change from baseline of cognitive development (Leiter R) Change from baseline of Pulmonary function (FVC) Change from baseline of Hearing Safety endpoints: Adverse events Vital signs Urinalysis Hematology and blood chemistry rhLAMAN antibody and inhibitory antibody | — |
