The objective of this research study is to conduct a pivotal phase 3 trial of treatment with the investigational drug dichloroacetate (DCA) in young children with deficiency of the pyruvate dehydrogenase complex (PDC). PDC deficiency (PDCD) is the most common cause of congenital lactic acidosis and is a frequently fatal metabolic disease of childhood for which no proven treatment exists. The investigators predict that DCA represents targeted potential therapy for PDCD because of its ability to increase both the catalytic activity and stability of the enzyme complex. The conclusions of numerous laboratory and clinical investigations are consistent with this postulate and have led to the designation of DCA as an Orphan Product for congenital lactic acidosis by the Food and Drug Administration. A novel Observer reported outcome (ObsRO) survey that is completed by study participant's parent/caregiver, is the efficacy outcome measure. Funding Source - FDA OOPD
