Neonatal jaundice is the most common cause of hospital readmission for term- and near term infants and its management poses a significant burden on the healthcare system.

Infants with isoimmune hemolytic disease, such as ABO or Rhesus (Rh) incompatibility, or glucose-6-phosphate dehydrogenase (G6PD deficiency), have an increased rate of red cell destruction and, thus, an increase in bilirubin production. Newborn infants have immature liver function and do not conjugate bilirubin well, which results in accumulation of unconjugated bilirubin. Thus, bilirubin levels may rise rapidly and intervention may be required. At present, phototherapy (PT) is the most frequently used treatment for hyperbilirubinemia; it converts unconjugated bilirubin to less toxic water soluble photoisomers that are then excreted in the urine without need for conjugation. Infants who do not respond to PT are treated by exchange transfusion (ET), considered a therapy of last resort because of associated morbidity and mortality. Both PT and ET enhance the elimination of, but have no impact on the production of bilirubin.

Stannsoporfin is a heme oxygenase inhibitor that acts to reduce bilirubin production. It is being developed for the management of neonatal jaundice.

Primary Outcome Measures:
  • Percent change from baseline in total serum bilirubin (TSB) (the baseline TSB is the TSB that qualifies for randomization) at 48 hours post-dose [ Time Frame: 48 hrs ]
    Percent change from baseline in total serum bilirubin (TSB) (the baseline TSB is the TSB that qualifies for randomization) at 48 hours post-dose

Secondary Outcome Measures:
  • Percent change from baseline in TSB (the baseline TSB is the TSB that qualifies for randomization) at 6, 12, 24, and 36 hours [ Time Frame: 6, 12, 24, and 36 hours ]
  • Total serum bilirubin area under the curve (AUC) above the baseline TSB (0 to 48 hours post-dose). [ Time Frame: 48 hrs ]
  • Peak serum bilirubin [ Time Frame: 0 to 48 hrs ]
  • Incidence of rebound hyperbilirubinemia defined as an increase in TSB above the age-specific threshold for initiating PT per the AAP Guidelines (AAP) following the discontinuation of the initial PT [ Time Frame: 30 days ]
  • Incidence of readmission to hospital for hyperbilirubinemia due to a TSB at or above the age specific threshold for PT [ Time Frame: 30 days ]
  • Duration of clinical requirement for PT [ Time Frame: 30 days ]
  • Incidence of adverse events (AE) and serious adverse events (SAE's) [ Time Frame: 30 days ]
  • Changes in vital sign measurements [ Time Frame: 30 days ]
  • Results of physical exam (PE), including growth measurements [ Time Frame: 30 days ]
  • Results of neurologic exam, including eye and hearing assessment [ Time Frame: 30 days ]
  • Electrocardiographic (ECG) assessments [ Time Frame: 14 days ]
  • Clinical laboratory tests including hematology, serum chemistries, liver function and renal function tests [ Time Frame: 30 days ]

  2. Parental or guardian consent
  3. Birth weight ≥ 2500 grams
  4. At or above the age-specific threshold for initiating PT per the AAP guidelines based on measurement of TSB

Abnormal renal function defined as creatinine and/or blood urea nitrogen >2 times the ULN 4. Any other clinically significant abnormalities on screening laboratory evaluation (including ECG) that in the opinion of the investigator makes the patient unsuitable for the clinical trial 5. Apgar score ≤6 at age 5 minutes 6. An unexplained existing rash or skin erythema 7. Prior exposure to PT 8. Clinical suggestion of neonatal thyroid disease or current uncontrolled thyroid disease in the mother (maternal Hashimoto's disease is not exclusionary) 9.

Maternal use of phenobarbital 30 days before, or after delivery, if breast-feeding 15. Maternal current drug or alcohol abuse, or maternal history of drug or alcohol abuse that, in the opinion of the Investigator, would not make the patient a suitable candidate for participation in the clinical trial 16. Significant congenital anomalies or infections 17. Risk of requiring surgery or exposure to operating room (OR) lights in the first 2 weeks of life 18. Persistent hypoglycemia (blood glucose <40 mg/dL) 19. Temperature instability defined as temperature consistently (3 consecutive times) <36ºC and/or >37.5ºC axillary 20.

Exposure to any investigational medications or devices after delivery, or participation in another clinical trial while participating in this trial 25. Any other concurrent medical condition, which in the opinion of the Investigator, makes the patient unsuitable for the clinical trial
