Trial of Late Surfactant for Prevention of Bronchopulmonary Dysplasia (TOLSURF)
April 21, 2021 updated by: Roberta Ballard
Trial of Late Surfactant for Prevention of Bronchopulmonary Dysplasia: A Study in Ventilated Preterm Infants Receiving Inhaled Nitric Oxide
The purpose of this study is to determine if late doses of Infasurf surfactant given when patients are receiving inhaled nitric oxide will interact to improve surfactant function and increase survival without BPD in treated infants.

Detailed Description
This is a multi-center, blinded, randomized controlled clinical trial to evaluate the effects of booster doses of exogenous surfactant (Infasurf®, calfactant) in addition to inhaled nitric oxide (iNO) on the outcome of survival without bronchopulmonary dysplasia (BPD, or chronic lung disease of prematurity, characterized by chronic lung dysfunction) at 36 weeks' post-menstrual age (PMA) in extremely low gestational age (ELGAN) infants that are at high risk of the development of BPD.
This multi-center trial, with a planned enrollment of 524 infants, will also enable us to evaluate for any adverse effects of late surfactant treatment on short- and long-term outcomes, as we will be collecting data on effects of dosing of late surfactant, co-morbidities of prematurity and neurodevelopmental and pulmonary outcome at 1 year and 24 months corrected age.
In addition, we will collect biological specimens for evaluation of the effects of late surfactant replacement therapy (administered as described in this trial) on surfactant function and inflammatory markers.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Infasurf surfactant (ONY, Inc.)
Infants already receiving inhaled nitric oxide will receive scheduled doses of late surfactant (Infasurf) on study days 0, 2, 4, 6 and 8.
|
Late doses of Infasurf 3ml/kg will be given to infants on study days 0, 2, 4, 6 and 8 as long as infant remains intubated.
Other Names:
|
Sham Comparator: Sham (No Treatment)
Infants already receiving inhaled nitric oxide will receive "Sham (no treatment)" doses on study days 0,2,4,6, and 8.
|
Late doses of Sham (No treatment) will be given to infants on study days 0, 2, 4, 6 and 8 as long as infant remains intubated.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Survival Without BPD at 36 Weeks Post Menstrual Age.
Time Frame: 36 weeks post menstrual age +/- 1 week
|
BPD was diagnosed as need for respiratory support with either positive pressure and/or oxygen as evaluated by physiological oxygen/flow reduction.
|
36 weeks post menstrual age +/- 1 week
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Survival Without BPD at 40 Weeks
Time Frame: 40 weeks PMA +/- 1 week
|
BPD was diagnosed as need for respiratory support with either positive pressure and/or oxygen as evaluated by physiological oxygen/flow reduction.
|
40 weeks PMA +/- 1 week
|
Respiratory Outcomes of TOLSURF Infants at 1 Year Corrected Age
Time Frame: 1 year
|
Evaluation of respiratory outcome through the first 12 months after birth.
questionnaires were administered by phone at 3,6,9 and 12 months to determine respiratory resource use (medications, home support, and hospitalization) No Pulmonary Morbidity (NoPM) was reported for infants who had no resource use in any quarter and Persistent PM was reported for infants having resource use in 3 or 4 quarters.
|
1 year
|
Pulmonary Outcomes Through 2 Years of Age
Time Frame: 2 years
|
Evaluation of pulmonary outcome at 24 months of age.
Evaluation of persistent wheezing based on reported wheezing during both first and second year of life.
|
2 years
|
Percentage of Participants With Neurodevelopmental Impairment (NDI) at 2 Years.
Time Frame: 2 years
|
At 24 months corrected age, children underwent neuropsychological testing with the Bayley Scales of Infant Development-Third Edition (Bayley-3), and composite cognitive, language, and motor scores were collected as well as subscale scores in receptive and expressive speech and fine and gross motor.
Infants with greater than one impairment as identified by testing were classified as having neurodevelopmental impairment.
