Phase II Pilot Randomized Study of Sodium Dichloroacetate in Patients With Congenital Lactic Acidemia

March 24, 2015 updated by: University of California, San Diego

OBJECTIVES: I. Determine the pharmacokinetics of sodium dichloroacetate (DCA) in patients with congenital lactic acidemia.

II. Determine the efficacy of DCA in decreasing the frequency and/or severity of acute episodes of acidotic illness, improving linear growth, improving neurological or developmental function, or slowing neurological or developmental deterioration in these patients.
