5. Maternal use of phenobarbital 30 days before, or after delivery, if breast-feeding
6. 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 subject a suitable
candidate for participation in the clinical trial
7. Apgar score =< 6 at age 5 minutes
8 Significant congenital anomalies or infections
9. Cardiorespiratory distress, defined as a respiratory rate >60 breaths per minute at time of enrollment unless a diagnosis of transient tachypnea of the newborn (TTN) has been made
10. Any abnormal auditory or ophthalmologic findings at Screening
- Subjects who fail initial auditory screen may be rescreened
11. Any excess risk of requiring surgery or exposure to operating room (OR) lights in the foreseeable future
12. Clinically significant abnormalities on screening laboratory evaluation
13. Elevated direct or conjugated bilirubin (>1.0 mg/dL if the TSB is <5.0 mg/dL or
>20% of the TSB if the TSB is >= 5.0 mg/dL)
14. Persistent hypoglycemia (blood glucose <40 mg/dL) despite standard-of-care
treatment
15. Alanine aminotransferase and/or aspartate aminotransferase > 2 times the ULN
16. Abnormal renal function defined as creatinine and/or blood urea nitrogen >2 times the ULN
17. Any blood smear finding of structural red cell abnormalities, such as spherocytosis, not caused by isoimmune hemolysis
18. Temperature instability defined as temperature consistently (3 consecutive times)
<36ºC and/or >37.5ºC axillary
19. Use of photosensitizing drugs or agents (see Appendix D)
20. Use of IVIG or albumins
21. Postdelivery treatment with medications that are known or suspected to displace
bilirubin from albumin (eg, ceftriaxone or sulfa-based antibiotics)
22. Other serious morbid conditions, e.g., pulmonary disease, cardiovascular disease
23. Exposure to any investigational medications or devices after delivery, or participation in another clinical trial while participating in this trial;
24. Any other concurrent medical condition, which in the opinion of the Investigator,
makes the subject unsuitable for the clinical trial
25. Unwillingness for parents/guardians to adhere to recommendations regarding light precautions |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy outcome will be based on total serum bilirubin (TSB) measurements adjusted for phototherapy (PT) initiation at both baseline and at 48 hours after treatment. In particular, the change in adjusted TSB levels from baseline to 48 hours after treatment will be considered.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Change in adjusted TSB levels from baseline to 48 hours after treatment. |
|
E.5.2 | Secondary end point(s) |
Secondary efficacy endpoints are the following:
- Unadjusted change from baseline to 48 hours in TSB measurements
- Adjusted and unadjusted change from baseline in TSB measurements at various other timepoints
- Proportion of subjects who require phototherapy (PT)/exchange transfusion
- Time to PT/exchange transfusion
- Duration of PT
- Time to hospital discharge
Safety will be based on the following variables:
- Reported adverse events (AEs)
- Vital sign measurements
- Physical examinations
- Electrocardiogram (ECG) recordings
- Hearing assessments
- Vision assessments
- Neurologic assessments
- Dermatologic reactions
- Clinical laboratory tests |
