Outcome Measures
Primary Outcomes (5)
Area under the plasma concentration versus time curve 0-24 hours for sildenafil
IV study dose 0-15 min,1-2,3-4,12-14,24-30,48-56hr after flush.Clinical care: IV <0.5hr before dose <15 min & 3-4hr after flush <0.5hr before next dose. Enteral <0.5hr before dose, 1-2 & 3-4hr after dose, <0.5hr before next dose. 22-26hr after last dose
Peak plasma concentration of sildenafil
IV study dose 0-15 min,1-2,3-4,12-14,24-30,48-56hr after flush.Clinical care: IV <0.5hr before dose <15 min & 3-4hr after flush <0.5hr before next dose. Enteral <0.5hr before dose, 1-2 & 3-4hr after dose, <0.5hr before next dose. 22-26hr after last dose
Clearance of sildenafil
IV study dose 0-15 min,1-2,3-4,12-14,24-30,48-56hr after flush.Clinical care: IV <0.5hr before dose <15 min & 3-4hr after flush <0.5hr before next dose. Enteral <0.5hr before dose, 1-2 & 3-4hr after dose, <0.5hr before next dose. 22-26hr after last dose
Volume of distribution at steady state
IV study dose 0-15 min,1-2,3-4,12-14,24-30,48-56hr after flush.Clinical care: IV <0.5hr before dose <15 min & 3-4hr after flush <0.5hr before next dose. Enteral <0.5hr before dose, 1-2 & 3-4hr after dose, <0.5hr before next dose. 22-26hr after last dose
Half life of sildenafil
IV study dose 0-15 min,1-2,3-4,12-14,24-30,48-56hr after flush.Clinical care: IV <0.5hr before dose <15 min & 3-4hr after flush <0.5hr before next dose. Enteral <0.5hr before dose, 1-2 & 3-4hr after dose, <0.5hr before next dose. 22-26hr after last dose
Secondary Outcomes (3)
Number of subjects with adverse events as a measure of safety and tolerability.
From the time of the first dose to 3 days after the last dose; serious adverse events will be collected from the first dose of sildenafil to 7 days after the last dose of sildenafil
Correlation between serum and dried blood spot samples
1-7 days
Evaluate P450 single nucleotide polymorphisms (SNPs)
2-7 days
Study Arms (2)
sildenafil, standard of care
NO INTERVENTIONInfants receiving sildenafil as standard of care
sildenafil administered for study
OTHER1 dose of sildenafil administered for study
Interventions
A single IV dose of sildenafil will be administered over 90 minutes with no greater than a 15-minute flush. Final dose to be determined based on at least the first 4 participants enrolled in Cohort 1; final dose expected to be a single dose between 0.25 and 0.5 mg/kg.
Eligibility Criteria
You may qualify if:
- Cohort 1:
- Gestational age 28 weeks or less receiving sildenafil as standard of care \< 365 postnatal days
- Cohort 2:
- Gestational age 28 weeks or less
- postnatal days of age
- Mechanical ventilation or nasal continuous positive airway pressure (NCPAP) or high-flow nasal cannula
- Intravenous line in place
You may not qualify if:
- Cohort 1:
- Any condition that would make the participant, in the opinion of the investigator, unsuitable for the study
- Cohort 2:
- Previous exposure to sildenafil within 7 days prior to enrollment
- Any condition that would make the participant, in the opinion of the investigator, unsuitable for the study
- History of allergic reactions to sildenafil
- AST \> ULN or ALT \> 3x ULN
- Currently on a vasopressor for hypotension
- Known sickle cell disease
