Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Compare 3-year event-free survival (EFS) between patients who receive Blina-14 intensification with this historical controls from CCCG-ALL2015 and CCCG-ALL2000 | The expected study duration is approximately 5 years. | The primary historical control cohort consists of the patients on the CCCG-ALL2020 trial determined as LR after remission indiction, received 2xHDMTX during consolidation and did not receive Bliniatumomab. As of end of 2024, this cohort contains 1111 patients, with 3-year EFS 0.963 and standard error 0.0087, 95% confidence interval \[0.953,0.980\] . The sample size and power assessment below is based on these data. The primary comparison is between the patients on this trial who are determined as LR after remission induction to the historical cohort described above, on 3-year EFS probability. .Power of the above test procedure is assessed by a simulation study. Historical control is set from the preliminary data as S0=0.963,v0\^2=0.0087\^2. For the current trial total sample size is set to n=2325 with 5 year accrual.LN distribution is chosen for its good assemblance of the EFS functions of the LR cohorts in the historical data. |
| Secondary | Estimate event-free survival (EFS) in patients with deep remission (FCM MRD19<0.01% and Ig-NGS MRD46<10-6) who received Maintenance-2' with reduced intensity chemotherapy | Approximately 6.5 years. | The EFS functions will be estimated by the Kaplan-Meier method along with 95% confidence intervals at specified timepoints (e.g., 1, 3, 5 years since diagnosis). |
| Secondary | Estimate overall survival (OS) in patients with deep remission (FCM MRD19<0.01% and Ig-NGS MRD46<10-6) who received Maintenance-2' with reduced intensity chemotherapy | Approximately 6.5 years. | The OS functions will be estimated by the Kaplan-Meier method along with 95% confidence intervals at specified timepoints (e.g., 1, 3, 5 years since diagnosis). |
| Secondary | Estimate cumulative incidence of relapse (CIR) in patients with deep remission (FCM MRD19<0.01% and Ig-NGS MRD46<10-6) who received Maintenance-2' with reduced intensity chemotherapy | Approximately 6.5 years. | The CIR curve will be estimated by Kalbafleisch-Prentice method, along with 95% confidence intervals. |
| Secondary | Compare event-free survival (EFS) to those of historical cohorts (CCCG-ALL-2015 and CCCG-ALL2020) | Approximately 6.5 years. | The EFS functions will be estimated by the Kaplan-Meier method along with 95% confidence intervals at specified timepoints (e.g., 1, 3, 5 years since diagnosis). Standard error will be estimated using the default procedure in R. Follow up of the historical comparison cohort (CCCG-ALL-2020 and 2015) will continue during the course of the current trial. Comparisons of EFS will be performed using two-sided log-rank test. Multivariable regression modeling including trial (CCCGALL-2025 vs. 2020 or 2015) and other known prognostic factors as main effects may also be performed, using the Cox models. |
| Secondary | Compare overall survival (OS) to those of historical cohorts (CCCG-ALL-2015 and CCCG-ALL2020) | Approximately 6.5 years. | The OS functions will be estimated by the Kaplan-Meier method along with 95% confidence intervals at specified timepoints (e.g., 1, 3, 5 years since diagnosis). Comparison of OS functions will be conducted using the two-sided log-rank test. Standard error will be estimated using the default procedure in R. Follow up of the historical comparison cohort (CCCG-ALL-2020 and 2015) will continue during the course of the current trial. Comparisons of OS will be performed using two-sided log-rank test.

| Secondary | Compare cumulative incidence of relapse (CIR) to those of historical cohorts (CCCG-ALL-2015 and CCCG-ALL2020) | Approximately 6.5 years. | CIR functions of relapse will be estimated by the Kalbafleisch-Prentice method. Follow up of the historical comparison cohort (CCCG-ALL-2020 and 2015) will continue during the course of the current trial. Comparisons of CIR will be performed by Gray's test. Multivariable regression modeling including trial (CCCGALL-2025 vs. 2020 or 2015) and other known prognostic factors as main effects may also be performed, using the Fine-Gray models. |
| Secondary | Compare event-free survival (EFS) between patients with deepen remission (FCM MRD19<0.01% and Ig-NGS MRD46<10-6) who receive one course of Blina-14 and those who recevive two courses of Blina-14. | Approximately 6.5 years | The EFS functions will be estimated by the Kaplan-Meier method along with 95% confidence intervals at specified timepoints (e.g., 1, 3, 5 years since diagnosis). Standard error will be estimated using the default procedure in R. Comparisons of EFS will be performed using two-sided log-rank test.
