Main objective of the trial

The primary objective of this study is to demonstrate that rhBSSL improves growth in preterm infants as compared with placebo when administered in infant formula or PBM.

Protection of trial subjects

The study will be conducted according to the International Conference on Harmonisation harmonised tripartite guideline E6(R1): Good Clinical Practice ensuring that the rights, safety and well-being of patients are protected, consistent with the principles that have their origin in the Declaration of Helsinki. The conduct of the study in neonatology intensive care units allowed for the continuous monitoring of patient safety and the accessibility to any necessary therapeutic measures. Furthermore the blood volume to be drawn from the preterm infants was strictly controlled. Serum levels of possible rhBSSL antibodies was determined at Baseline, at the end of treatment (Day 29), and 3 months after the start of treatment and followed further if antibodies were detected. Each individual patient with a positive anti-drug antibody response was checked for immune related adverse events (and vice versa).

Recruitment details

74 study centres in Europe participated in the trial and patients were randomised at 54 of them. First patient was screened on July 26 2011 and last patient randomised on 3 June 2013.

Screening details

After informed consent was collected from the parents/legally authorised representatives, patients entered a screening period of a maximum of seven days. The screening and baseline visit could also take place on the same date. A total of 415 patients were randomized and treatment was initiated in 412 patients.

rhBSSL Full Analysis Set

Arm description

Patients received rhBSSL Day 1 (Baseline) as soon as possible after randomization (either on the day of randomization or the day after). The administration of rhBSSL continued for 4 weeks. Follow-up visits occurred at 3 months after the first dose of study drug and at 12 months corrected age. The FAS consisted of all patients randomly assigned to treatment who had at least one dose of study medication, an assessment of body weight at baseline, and at least one body weight assessment post baseline. The patients were grouped according to randomized treatment. All 207 patients randomized to the rhBSSL group started treatment but one patient was excluded from the FAS due to lack of body weight data.

Dosage and administration details

15 mg of rhBSSL (sterile powder for oral solution) will be reconstituted in 1mL of sterile water before addition to 100 mL pasteurised breast milk of infant formula. The food volume should be in the range of 150-180 mL/kg/day. Each feeding during the 4 week treatment period should contain study drug.

Placebo Full Analysis Set

Arm description

Patients received placebo Day 1 (Baseline) as soon as possible after randomization (either on the day of randomization or the day after). The administration of placebo continued for 4 weeks. Follow-up visits occurred at 3 months after the first dose of study drug and at 12 months corrected age. The FAS consisted of all patients randomly assigned to treatment who had at least one dose of study medication, an assessment of body weight at baseline, and at least one body weight assessment post baseline. The patients were grouped according to randomized treatment. Of the 208 patients that was randomized to the placebo group, 3 did not start treatment and one patient was excluded from the FAS due to lack of body weight data.

Notes
[1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
Justification: 415 patients were randomly assigned to treatment (rhBSSL=207, placebo=208). Treatment was initiated in 412 patients (rhBSSL=207, placebo=205). The full analysis set (FAS) was used as the primary population for the analyses of the primary and secondary efficacy variables and it is the FAS that baseline characteristics are described for. 410 patients were included in the FAS (rhBSSL=206, placebo=204). Exclusion from the FAS was due to lack of body weight data post baseline.

End point title

Growth Velocity during 4 weeks of treatment

End point description

The primary efficacy variable is growth velocity in grams per kilogram per day during 4 weeks of treatment. The primary efficacy measurement (growth velocity) was made by frequent (at least 3 times per week) measurements of the infant’s weight during treatment. If a patient withdrew before Day 29 then growth velocity was derived using weight assessments up to their last available assessment. In order to calculate growth velocity, the natural log-transformed value of the baseline and all post baseline weight assessments for each patient was calculated. A linear regression model was then fitted for each patient with a response variable of log(weight) and a predictor variable of time. Growth velocity for each patient was estimated as the slope arising from the regression model, and needed to be multiplied by 1000 for conversion into the desired unit.

End point description

Feeding utilization variable (α) which is defined by the differential equation (dm/dt)=αV(t), t>=1 where • α is the efficiency in feeding utilization (g/L) • V(t) is the volume (ml/kg) at time t • m is the weight (g) and • t is the time (day) For each patient all daily feeding volumes between Day 1 and Week 4 and the corresponding body weight values on these days (where missing body weight values will be imputed) will be used to derive nonlinear ordinary least square (OLS) parameter estimates for α, separately for each patient. α will be constrained to be ≥ 0, and the initial value will be set to 0.5. The equation for weight will be fitted by a static model. The model is an appropriate simplification of the mathematical model of weight change with adaption in [Thomas, 2009]. The computed α is an estimate of the metabolic efficiency.

Bayley III Cognitive Domain at 12 Months Corrected Age: Scaled Scores

End point description

The Bayley-III is an individually administered instrument that assesses the developmental functioning of infants and young children between 1 month and 42 months of age, across five domains: cognitive, motor (including the fine and gross motor subtests), language (including the receptive and expressive communication subtest), social-emotional, and adaptive behavior. Assessments of the cognitive, motor and language domains are conducted using items administered to the child; assessment of the social-emotional and adaptive behavior domains are conducted using parent/primary caregiver response to a questionnaire. Scaled scores represent a child’s performance on a subtest relative to his or her same-age peers. They are derived from the total raw scores (which is the sum of the number of points earned for a subtest) on each of the subtests and are scaled to a metric with a range of 1 to 19, a mean of 10, and a standard deviation of 3.

Bayley III Cognitive Domain at 12 Months Corrected Age: Composite Scores

End point description

The Bayley-III is an individually administered instrument that assesses the developmental functioning of infants and young children between 1 month and 42 months of age, across five domains: cognitive, motor (including the fine and gross motor subtests), language (including the receptive and expressive communication subtest), social-emotional, and adaptive behavior. Assessments of the cognitive, motor and language domains are conducted using items administered to the child; assessment of the social-emotional and adaptive behavior domains are conducted using parent/primary caregiver response to a questionnaire. Composite scores are based on various sums of subtest scaled scores for the Language, Motor , and Adaptive Behaviors composites, and composite equivalents for the scaled scores from the Cognitive and Social-Emotional Scales. The composite scores are scaled to a metric with a range of 40 to 160, a mean of 100, and a standard deviation of 15.

End point description

A sensitivity analysis will be performed for the primary endpoint. Growth velocity (g/kg/day) will be calculated using a 2-Point weight model (Patel, 2009). The net weight gain over time will be divided by the weight at Day 1. For each patient, growth velocity will be calculated using the following formula: GV= (1000 x (Wn x W1)) / (Wn (Dn - D1)) where w1=weight in grams at Day 1 and wn=weight in grams at Day n (Day n being the last available weight assessment during the treatment period, taken on or before Day 29).

Assessments of the cognitive, motor and language domains are conducted using items administered to the child; assessment of the social-emotional and adaptive behavior domains are conducted using parent/primary caregiver response to a questionnaire. Composite scores are based on various sums of subtest scaled scores for the Language, Motor , and Adaptive Behaviors composites, and composite equivalents for the scaled scores from the Cognitive and Social-Emotional Scales. The composite scores are scaled to a metric with a range of 40 to 160, a mean of 100, and a standard deviation of 15.
