RTS is defined as any one of the following:
(1) supplemental oxygen less than (<) 2 Liter per minute (L/min) without positive pressure (including nasal cannula),
(2) positive pressure support (including continuous positive airway pressure [CPAP], nasal cannula oxygen greater than (>) 2 L/min),
(3) positive pressure ventilation (high frequency oscillation ventilation and technologies with positive pressure tidal volume breaths, such as mechanical ventilation, nasal intermittent positive pressure ventilation [NIPPV]).
Time to final weaning off RTS as compared to a standard neonatal care group will be reported.

Secondary Outcome

5. Number of Days of Respiratory Medication use
Time Frame: From NICU discharge through 12 months CA
Number of days of respiratory medication use (for example, bronchodilators, steroids, leukotriene inhibitors, diuretics) will be reported.

6. Incidence of Signs and Symptoms of Respiratory Disease as Assessed by a 28-day Caregiver-administered Diary Ending at 12 Months Corrected age (CA)
Time Frame: 11 months CA through 12 months CA
Incidence of signs and symptoms of respiratory disease (yes/no) at 12 months CA as assessed by a 28-day caregiver-administered diary recording episodes of wheezing, coughing, and respiratory medication will be reported.

7. Incidence of Chronic Respiratory Morbidity (CRM1) Through 12 Months Corrected age (CA)
Time Frame: From NICU discharge through 12 months CA
A participant will be defined as having CRM1 if he or she experienced/required at least 1 of the 3 following clinical/treatment events, as reported by parents/caregivers and captured by the pulmonary morbidity assessment on at least two 3-month quarters over a 12-month time period: 1. Emergency room visit or hospitalization associated with a respiratory diagnosis, 2. Home RTS, 3. Daily use of respiratory medications (e.g., bronchodilators, steroids, leukotriene inhibitors, diuretics) as reported by caregivers on the pulmonary morbidity assessment. Incidence of CRM1 through 12 months CA will be reported.

8. Incidence of Chronic Respiratory Morbidity Including Symptoms of Respiratory Disease (CRM2) Through 12 Months Corrected age (CA)
Time Frame: From NICU discharge through 12 months CA
A participant will be defined as having CRM2 if he or she experienced/required at least 1 of the 4 following clinical/treatment events, as reported by parents/caregivers and captured by the pulmonary morbidity assessment on at least two 3-month quarters over a 12-month time period: 1). Emergency room visit or hospitalization associated with a respiratory diagnosis, 2). Home RTS, 3). Daily use of respiratory medications (e.g., bronchodilators, steroids, leukotriene inhibitors, diuretics) as reported by caregivers on the pulmonary morbidity assessment, 4). Symptoms of respiratory disease as defined by presence of cough without cold, or wheeze at least once per week. Incidence of CRM2 through 12 months CA will be reported.

9. Severity of Chronic Respiratory Morbidity (CRM3) Through 12 Months Corrected age (CA), as Determined by the Chronic Lung Disease (CLD) of Infancy Severity Score
Time Frame: From NICU discharge through 12 months CA
Severity of chronic respiratory morbidity (CRM3) through 12 months CA will be reported, as determined by the CLD of infancy severity score that will include components such as respiratory hospitalizations, RTS use, and use of respiratory medications.

10. Incidence of Intraventricular Hemorrhage (IVH) Through Postmenstrual age (PMA) 40 weeks, as Assessed by Cranial Ultrasound
Time Frame: Baseline through 40 Weeks PMA
Incidence of IVH through PMA 40 weeks, as assessed by cranial ultrasound, will be reported.

11. Motor Function at 12 Months Corrected age (CA), as Measured by Alberta Infant Motor Scales (AIMS)
Time Frame: At 12 months CA
The AIMS is a measure of early motor maturation used for assessment of infants at risk for motor delay, focusing on attainment of motor milestones and development of postural control. It consists of 58 items, including assessments in 4 postural positions: prone (21 items), supine (9 items), sitting (12 items) and standing (16 items). Each item is scored as 'observed' or 'not observed'. The scorer identifies the least and most mature item observed. Motor function at 12 months CA, as measured by AIMS will be reported.

12. Functional Status as Assessed by PREMature Infant Index (PREMII) at Postmenstrual Age (PMA) 36 Weeks.
Time Frame: At 36 weeks PMA
PREMII is a Clinician-Reported Outcome (ClinRO) assessment used to capture overall functional maturation of extremely preterm neonates. Functional Status is defined as what the infant can do with respect to 8 key functional areas (feeding, weight gain, thermoregulation, respiratory support, apnea, bradycardia, desaturation events, and oxygen administration), as a reflection of the infant's overall health and development.

13. Incidence of Retinopathy of Prematurity (ROP)
Time Frame: At 36 weeks PMA
The ROP examination will consist of a dilated fundus examination. Typically ROP is classified according to the International Classification and is subdivided into Stage 1 (demarcation line), Stage 2 (ridge), Stage 3 (ridge with extraretinal fibrovascular proliferations), Stage 4 (subtotal retinal detachment), and Stage 5 (total retinal detachment). Incidence of ROP will be reported.

14. Incidence of Mortality
Time Frame: From birth through 12 months CA
Mortality from birth through 12 months CA will be reported.

15. Exposure-response of Insulin-like Growth Factor-1 (IGF-1)
Time Frame: Up to 12 months CA
Exposure response of IGF-1 will be evaluated using (Pharmacokinetic/Pharmacodynamic [PK/PD]) relationship of IGF-1 between respiratory and neurologic endpoints.

After approximately 75 participants (approximately 25 participants in each treatment group) have completed the postmenstrual age (PMA) 40 weeks visit, an independent data monitoring committee (DMC) will assess safety data and may authorize enrollment of participants of GA between 23 weeks +0 days and 27 weeks +6 days, inclusive.

Exclude criteria
