Arm Groups
Arm | Description | Assigned Intervention |
---|---|---|
Experimental Sildenafil cohort 1 |
Within cohort 1 infants will be randomized using a 3:1 scheme to receive sildenafil or placebo. Infants randomized to sildenafil will receive 0.125 mg/kg daily every 8 hours intravenously (IV), or 0.25 mg/kg daily every 8 hours enterally for 28 days. |
|
Placebo Comparator Placebo cohort 1 |
Infants randomized to the placebo treatment group will receive the equivalent of dextrose 5% (sugar water) to be administered IV or enteral use. |
|
Experimental Sildenafil cohort 2 |
Cohort 2 infants will receive sildenafil 0.5 mg/kg daily every 8 hours intravenously (IV) or 1 mg/kg daily every 8 hours enterally for 28 days. |
|
Placebo Comparator Placebo cohort 2 |
Infants randomized to the placebo treatment group will receive the equivalent of dextrose 5% (sugar water) to be administered IV or enteral use. |
|
Experimental Sildenafil cohort 3 |
Cohort 3 infants will receive sildenafil 1 mg/kg daily every 8 hours intravenously (IV) or 2 mg/kg daily every 8 hours enterally for 28 days. |
|
Placebo Comparator Placebo cohort 3 |
Infants randomized to the placebo treatment group will receive the equivalent of dextrose 5% (sugar water) to be administered IV or enteral use. |

Detailed Description
This will be a multi-center, randomized, placebo-controlled, sequential dose escalating, double masked, safety data study of sildenafil in premature infants. This is a Phase II study design, premature infants (inpatient in neonatal intensive care units) will be randomized in a dose escalating approach 3:1 (sildenafil: placebo) into 3 cohorts with escalating doses of sildenafil. There will be 40 randomized and dosed participants in each cohort for a total of up to 120 participants. Cohort 1 sildenafil dose will be 0.125 mg/kg q 8 hours IV or 0.25 mg/kg q 8 hours enteral. Cohort 2 sildenafil dose will be 0.5 mg/kg q 8 hours IV or 1.0 mg/kg q 8 hours enteral. Cohort 3 sildenafil dose will be 1 mg/kg q 8 hours IV or 2 mg/kg q 8 hours enteral.
