Stannsoporfin With Light Therapy for Newborn Babies With Jaundice

Phase 2
Completed
Conditions
Hyperbilirubinemia, Neonatal
Jaundice, Neonatal
Interventions
Procedure: Phototherapy
Drug: Placebo
Registration Number
NCT01887327
Lead Sponsor
InfaCare Pharmaceuticals Corporation, a Mallinckrodt Company
Brief Summary

It is normal for red blood cells to die, even in newborn babies. The waste from that is called bilirubin. The liver clears bilirubin out of the body.

Some babies are born with illness that makes red blood cells die too fast, so the liver is not strong enough to keep up with it.

The yellowish color in eyes or skin means there is too much bilirubin in the body. It can be dangerous if a baby's bilirubin gets too high.

Special lights are put on jaundiced babies (called phototherapy) to help the liver get rid of bilirubin.

This study tests an experimental drug to see if it can help the liver even more, by safely cutting down the amount of bilirubin the body is making in the first place.

Detailed Description

Participants randomized (1:1:1) to treatment groups will be term or near-term infants with isoimmune hemolytic disease or glucose-6-phosphate dehydrogenase (G6PD) deficiency.

Inclusion Criteria
  1. Term and near term infants ≥35 and ≤ 43 weeks gestational age (GA), age 0-48 hours with antibody (ABO) or rhesus factor (Rh) incompatibility (anti C, c, D, E or e) who are Coombs positive, or age 0-72 hours with G6PD deficiency
  2. Parental or guardian consent
  3. Birth weight ≥ 2500 grams
  4. At or above the age-specific threshold for initiating phototherapy (PT) per the American Academy of Pediatrics (AAP) guidelines based on measurement of total serum bilirubin (TSB)
  5. Parents agree to observe light precautions for 10 days post treatment
Exclusion Criteria
  1. Elevated direct bilirubin ≥2 mg/dL, OR > 20% of the total serum bilirubin
  2. Alanine aminotransferase (ALT) > 2 times the upper limit of normal (ULN) and/or aspartate aminotransferase (AST) > 3 times ULN
  3. 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 electrocardiogram (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. Cardio-respiratory distress, defined as a respiratory rate >60 breaths per minute at time of enrollment
  10. Any abnormal auditory or ophthalmologic findings on screening physical exam
  11. Treatment or need for treatment in the neonate with medications that are photoreactive or may prolong the QT interval (erythromycin ointment for eye prophylaxis is permitted), or family history of Long QT syndrome
  12. Known porphyrias or risk factors for porphyrias, including family history
  13. A maternal history of systemic lupus erythematosus
  14. 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) <36 degrees centigrade (ºC) and/or >37.5 degrees centigrade (ºC) axillary
  20. Use of intravenous immunoglobulin (IVIg) or albumin prior to study drug administration
  21. Post-delivery treatment with medications that are known or suspected to displace bilirubin from albumin (e.g., ceftriaxone or sulfa-based antibiotics)
  22. Use of photosensitizing drugs or agents
  23. Unwillingness of parents/guardians to adhere to recommendations regarding light precautions
  24. 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

Primary Outcome Measures
NameTimeMethod
Total Serum Bilirubin (mg/dL)Baseline, 48 hours post-treatment

Total serum bilirubin (TSB) was measured at baseline (the measure that qualified the baby for inclusion) and at 48 hours after treatment. If a baby was discharged before 48 hours, the last measurement before discharge was used \[last observation carried forward (LOCF)\].

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Rebound Hyperbilirubinemiawithin 54 hours

Rebound hyperbilirubinaemia was defined as an increase in TSB above the age-specific threshold for initiating phototherapy, following the discontinuation of the initial phototherapy.

Time (Hour) at Which TSB First Crosses at or Below the Defined Age-specific Threshold for 54-hours Post-treatment (PT)within 54 hours

The hour that 50% of babies in the group (median) first crosses at or below the defined 54-hour threshold for the baby's age

Number of Participants With Phototherapy (PT) Failurewithin 30 days after discharge

PT failure was defined by any of the following:

* re-start of PT within 6 hours after stopping

* re-hospitalization for hyperbilirubinaemia

* use of intravenous immunoglobulin (IVIg)

* need for an exchange transfusion
