Recruitment details

This was an extension study in pediatric subjects diagnosed with one of three subtypes of juvenile idiopathic arthritis (JIA): extended oligoarticular JIA, enthesitis related arthritis (ERA), or psoriatic arthritis (PsA) had received at least one dose of Etanercept and completed approximately 96 weeks of participation in study 0881A1-3338.

Screening details

This study has 3 periods: Active treatment period, Withdrawal/Re-treatment period and Observational period.

Period 1 title

Parent Study

Is this the baseline period?

Allocation method

Non-randomised - controlled

Not blinded

Etanercept

Arm description

Subjects aged <18 years & weighed <=62 kg received Etanercept(Etn)SC dose of 0.8 mg/kg once a week, for active treatment period (ACT) for maximum of 96 months. Subjects who either met Wallace definition for clinically inactive disease for at least 6 months on Etn or who had a good clinical response & would benefit from withdrawal from Etn & were otherwise eligible entered withdrawal period. Subjects requiring re-treatment per investigator’s clinical judgment and otherwise eligible entered re-treatment period. Subjects who discontinued Etn prior to completing 96 weeks of active treatment in study 0881A1-3338 for any reason or not eligible to continue Etn in study B1801023 asked to enter observational period directly. Subjects from ACT,withdrawal/re-treatment period who discontinued Etn prior to completion of study, asked to participate in observational period. In observational period, all subjects followed up for a maximum of 96 months from the time of initial entry into this study.

Notes
[1] - Period 1 is not the baseline period. It is expected that period 1 will be the baseline period.
Justification: Period 1 has the data from the parent study. However, Overall study represents the participant flow for the extension study. Therefore, Overall study (Extension Study-96 months) has been selected as the baseline period.

Notes
[2] - 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: The worldwide number represents the subjects enrolled in the parent study. The results reported here are for extension study. Therefore, Overall study (Extension Study-96 months) has been selected as the baseline period and its is not same as worldwide number enrolled in the trial
[3] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period.
Justification: The Parent Study period, has the data of subjects form the parent study B1801014. The subjects in the extension study entered from the parent study, mentioned here as Overall study (Extension Study-96 months). So the number of subjects are not same.

Notes
[4] - The number of subjects transferring in and out of the arms in the period are not the same. It is expected the net number of transfers in and out of the arms in a period, will be zero.
Justification: The net number of transfers in and out of the arms in a period, is not zero as few subjects entered the withdrawal period directly from the parent study and were further transferred in observational period or re-treatment period.

End point description

Growth parameters included weight, height and body-mass index (BMI) were compared to the standard growth data by using Z-Score. Z-score is a statistical measure to evaluate how a single data point or mean compares to a standard. A Z-Score describes whether a mean is above or below the standard and how unusual the measurement is. Z-scores range from -3 to +3. A Z-score of 0 indicates the same mean, >0 a greater mean, and <0 a lesser mean than the standard. In this study, infant growth parameters were compared to a standard defined by Centers for Disease Control's growth charts. The analysis set included all subjects enrolled in extension study.

Change From Baseline in Z-Score at Month 12, 24, 36, 42, 48, 60, 72: Withdrawal Period: Extension Study

End point description

Growth parameters included weight, height and BMI were compared to the standard growth data by using Z-Score. Z-score is a statistical measure to evaluate how a single data point or mean compares to a standard. A Z-Score describes whether a mean is above or below the standard and how unusual the measurement is. Z-scores range from -3 to +3. A Z-score of 0 indicates the same mean, >0 a greater mean, and <0 a lesser mean than the standard. In this study, infant growth parameters were compared to a standard defined by Centers for Disease Control's growth charts. The WAS included those subjects who entered the withdrawal period. Only data collected in the withdrawal period was included. 99999 signifies that standard deviation was not estimable as only 1 subject was evaluated. Data for this endpoint was estimable till week 72 only.
