Expanded Access Treatment Protocol With DCA for Patients With PDCD

Expanded Access Treatment Protocol With Dichloroacetate Sodium for Patients With Pyruvate Dehydrogenase Complex Deficiency

Expanded Access (EA) will provide a transition to continue therapy for those patients who are currently in the open label extension of the Phase III study, SL 1009-01, while also allowing new patients diagnosed with PDCD who meet the eligibility criteria to also have access to therapy that would be otherwise unavailable.

Expanded Access (EA) will provide a transition to continue therapy for those patients who are currently in the open label extension of the Phase III study, SL 1009-01, while also allowing new patients diagnosed with PDCD who meet the eligibility criteria to also have access to therapy that would be otherwise unavailable. The Expanded Access program (EAP) will also allow the sponsor to extend the collection of long term safety data for the current open label patients, while also expanding to an additional population of patients beyond those currently in the SL 1009-01 study.

4. Females of reproductive age must be willing to use an effective method of barrier contraception for the duration of the study.-

Exclusion Criteria:

1. A genetic mitochondrial disease other than those stipulated under inclusion criteria
2. Primary, defined organic acidurias other than lactic acidosis (e.g., propionic aciduria)

6. Malabsorption syndromes associated with D-lactic acidosis
7. Renal insufficiency, defined as 1) a requirement for chronic dialysis or 2) serum creatinine ≥ 1.2 mg/dl or creatinine clearance <60 ml/min
