7. Liver function tests (aspartate aminotransferase/alanine aminotransferase [AST/ALT] levels) more than 2.5 times upper limit of normal values.

8. Known human immunodeficiency virus (HIV) or Hepatitis C virus (HCV) or hepatitis B surface antigen (HBsAg) positive, testing is not required.

9. Known significant renal impairment as indicated by serum creatinine of ≥1.4 mg/dL or estimated glomerular filtration rate (eGFR) of <45 mL/min.

10. Known history of hypersensitivity, allergic or adverse reactions to 5-aminolevulinic acid and sodium ferrous citrate.

11. Presence or history of uncontrolled systemic disease.

12. Female patients who are pregnant or breast-feeding.

13. Any other condition in the opinion of the investigator makes the patient unsuitable for study

14. Received any medication specified as contraindication for ACT or affecting blood concentration of ACT within 5 times the half-life of each medication before the first dose of study medication.
