NCT01236898
First received: November 8, 2010
Last updated: September 7, 2011
Last verified: August 2011
  Purpose

The aim of this study is to investigate pharmacokinetics and safety of N-acetylneuraminic acid in patients with Distal myopathy with rimmed vacuoles (DMRV) - hereditary inclusion body myopathy (hIBM). Dosages are 800mg single and three times a day and 800mg 3 times a day for 5 consecutive days. N-acetylneuraminic acid and N-glycolylneuraminic acid in serum and urine are measured before and after oral administration of N-acetylneuraminic acid.

Primary Outcome Measures:
  • Change in serum concentration of N-acetylneuraminic acid [ Time Frame: 24 hours before dosing and dosing days ] [ Designated as safety issue: No ]
    Patients with DMRV(hIBM) show low serum N-acetylneuraminic acid level.

  • Change in pharmacokinetic parameters of N-acetylneuraminic acid: AUCt [ Time Frame: 24 hours before dosing and dosing days ] [ Designated as safety issue: No ]
  • Change in amount of urinary excretion of N-acetylneuraminic acid [ Time Frame: 24 hours before dosing and dosing days ] [ Designated as safety issue: No ]
  • Safety(adverse events) [ Time Frame: Up to 5-7 days after dosing ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Change in serum concentration of N-glycolylneuraminic acid [ Time Frame: 24 hours before dosing and dosing days ] [ Designated as safety issue: No ]
  • Change in pharmacokinetic parameters of N-glycolylneuraminic acid: AUCt [ Time Frame: 24 hours before dosing and dosing days ] [ Designated as safety issue: No ]
  • Change in amount of urinary excretion of N-glycolylneuraminic acid [ Time Frame: 24 hours before dosing and dosing days ] [ Designated as safety issue: No ]
