   - Any medical condition or any laboratory abnormality or ECG abnormality that would, in
   the opinion of the investigator, contraindicate study participation.

   - Impaired liver function (e.g., alanine aminotransferase [ALT] ≥2 times the upper limit
   of normal [ULN] or bilirubin ≥2 times ULN), known active hepatic disease (e.g.,
   hepatitis), or evidence of clinically significant liver disease or other condition
   affecting the liver that may suggest the potential for an increased susceptibility to
   hepatic toxicity with oral gabapentin or pregabalin exposure.

   - Any history of renal disease that, in the opinion of the investigator, would
   contraindicate study participation; or subject had significantly impaired renal
