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 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
  • Total serum bilirubin area under the curve (AUC) above the baseline TSB (0 to 48 hours post-dose). [ Time Frame: 48 hrs ] [ Designated as safety issue: No ]
  • Peak serum bilirubin [ Time Frame: 0 to 48 hrs ] [ Designated as safety issue: No ]
  • 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 ] [ Designated as safety issue: No ]
  • Incidence of readmission to hospital for hyperbilirubinemia due to a TSB at or above the age specific threshold for PT [ Time Frame: 30 days ] [ Designated as safety issue: No ]
  • Duration of clinical requirement for PT [ Time Frame: 30 days ] [ Designated as safety issue: No ]
  • Incidence of adverse events (AE) and serious adverse events (SAE's) [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Changes in vital sign measurements [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Results of physical exam (PE), including growth measurements [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Results of neurologic exam, including eye and hearing assessment [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Electrocardiographic (ECG) assessments [ Time Frame: 14 days ] [ Designated as safety issue: Yes ]
  • Clinical laboratory tests including hematology, serum chemistries, liver function and renal function tests [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
