Research Excerpts

Overview

Tin mesoporphyrin (SnMP) is a competitive inhibitor of heme oxygenase. SnMP is being examined clinically for the treatment of hyperbilirubinemia.

NCT01887327 (2) [back to overview]Total Serum Bilirubin (mg/dL)

Change in Adjusted Total Serum Bilirubin (TSB) From Baseline to 48 Hours After Treatment.

The adjusted TSB is a calculation of the percentage difference of the TSB level from the age-specific threshold for PT initiation per the American Academy of Pediatrics (AAP) Guidelines, ie, an indication of the distance below the PT threshold at the time [(TSB - PT threshold/PT threshold) x 100%). (NCT00850993)
Timeframe: Baseline, 48 hours

Interventionpercentage difference from PT threshold (Median)
Cohort 1: Stannsoporfin 1.5 mg/kg-12.30
Cohort 2: Stannsoporfin 3.0 mg/kg-9.05
Cohort 3: Stannsoporfin 4.5 mg/kg-19.95
Placebo Control-5.7

Change From Baseline in Total Serum Bilirubin (TSB) at 48 Hours (ITT Population

Total bilirubin in blood serum was measured at baseline and at 48 hours after the shot. Change from baseline is calculated by subtracting the amount at baseline from the amount at 48 hours. Lower numbers are better. (NCT00850993)

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

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 (NCT01887327)

Total Serum Bilirubin (mg/dL)

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)]. (NCT01887327)
