Phamacological study to test safety of miglustat in patients with SPG11

Phase 1
Conditions
Spastic paraparesis type 11 (SPG11), caused by mutations in spatacsin protein, is characterized by the association of peripheral neuropathy, parkinsonism, ataxia, cognitive impairment, hypotrophy of the corpus callosum and retinal degeneration. The disease progresses with degeneration of motor and cognitive functions up to total dependence on caregivers. At the moment there are no therapies capable of modifying its natural history and progression.

Primary Outcome Measures
NameTimeMethod
Main Objective: Evaluate the tolerability and safety of miglustat administration in a group of 10 subjects with moderate form of SPG11;Secondary Objective: Quantize the glycosphingolipids and GM2 gangliosides in patient serum over the course of the study.<br>Evaluate changes in disease progression and severity (± 20% changes in clinical SPRS scores) during treatment with miglustat.;Primary end point(s): Percentage of subjects reporting serious / significant adverse reactions or changes in blood or neurophysiological parameters greater than ± 20% (or both) during the study assessed at the two follow-up visits at 12 weeks (T1) and 24 weeks (T2 ) from the start of the study with respect to the enrollment visit (T0);Timepoint(s) of evaluation of this end point: From the first day of drug administration (day after the enrollment visit) to the completion visit (T2, 24 weeks from enrollment).
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): Greater than ± 20% variations in plasma GM2 glycosphingolipid and ganglioside levels (expressed as percentages of the total pool of identified glycosphingolipids (e.g.% total profile, mean ± SD) (Fan et al., 2013) measured at T1 and T2 compared to measurement performed during the enrollment visit (T0).; Score changes greater than ± 20% in the scores of the clinical disease scales and questionnaires at T1 and T2 compared to the scores obtained at the enrollment visit (T0).;Timepoint(s) of evaluation of this end point: From the enrollment visit to the completion visit (T2, 24 weeks from enrollment).; From the enrollment visit to the completion visit (T2, 24 weeks from enrollment).
