Clinical Trial Summary

This phase III trial compares the effect of usual treatment of chemotherapy and steroids and a tyrosine kinase inhibitor (TKI) to the same treatment plus blinatumomab. Blinatumomab is a Bi-specific T-Cell Engager ('BiTE') that may interfere with the ability of cancer cells to grow and spread. The information gained from this study may help researchers determine if combination therapy with steroids, TKIs, and blinatumomab work better than the standard of care.

Description:

PRIMARY OBJECTIVE:

I. To compare the overall survival (OS) following induction with steroids + TKI + blinatumomab versus induction with steroids + TKI + chemotherapy.

SECONDARY OBJECTIVES:

I. To compare the rate of minimal residual disease (MRD) negativity for patients treated with chemotherapy versus (vs) blinatumomab at the end of first induction (week 15).

II. To evaluate the rate of the MRD negativity by treatment arm for those patients MRD positive after the first induction and administered of second induction.

III. To compare event free survival (EFS) for patients initially randomized for chemotherapy vs blinatumomab.

IV. To assess the toxicities of blinatumomab + TKI vs. TKI + chemotherapy in this patient population.

V. To assess the toxicities of the chemotherapy regimen in this patient population.

VI. To describe the outcome of patients who proceed to allogeneic stem cell transplant after treatment with blinatumomab + TKI only.

OUTLINE:

ARM A (PRE-INDUCTION): Patients receive prednisone orally (PO) once daily (QD) on days 1-21 and ponatinib hydrochloride (ponatinib) PO QD or dasatinib PO QD on days 1-21 based on investigator's choice.

Patients are randomized to 1 of 2 arms (Arm B or C). Patients undergo bone marrow aspiration with biopsy, lumbar punctures, echocardiogram (ECHO), and multigated acquisition (MUGA) scans as indicated by investigator.

ARM B (INDUCTION THERAPY):

CYCLE 1: Patients receive cyclophosphamide intravenously (IV) twice daily (BID) on days 1-3, dexamethasone PO or IV on days 1-4 and 11-14, cytarabine intrathecally (IT) on day 1, doxorubicin hydrochloride (doxorubicin) IV on day 4, vincristine sulfate (vincristine) IV on days 4 and 11, and methotrexate IT on day 8. Patients also receive Mesna 600mg/m^2 IV as a 'chemoprotectant' via continuous infusion on days 1-3, (beginning 1 hour prior to cyclophosphamide and completed by 12 hours after the last dose of cyclophosphamide).

CYCLE 2 (AGE 18-70): Starting in cycle 2, fit patients aged 18-70 receive dasatinib 70mg/day PO QD or ponatinib 30mg/day PO QD on days 1-21, methotrexate IV over 24 hours and IT on day 1, and cytarabine IV over 2 hours BID on days 2-3 of each cycle. On day 22 of cycle 2 or later, as soon as the absolute neutrophil count (ANC) is greater than 1000 cells/ul and platelets are greater than 50,000 cells/ul, patients receive hyper cyclophosphamide, vincristine, doxorubicin, and dexamethasone (CVAD) for 2 additional cycles.

CYCLE 2 (AGE > 70 or unfit < 70): Starting in cycle 2, patients age > 70 or younger unfit patients for Hyper-CVAD receive ponatinib PO QD or dasatinib PO QD on days 1-21 of each cycle. Patients also receive methotrexate IV over 24 hours and IT on day 1, and cytarabine IV over 2 hours BID on days 2-3 of each cycle. Cycle 1 and 2 regimens are each repeated once starting on day 22 of cycle 2, or later, but as soon as the ANC is greater than 1000 cells/ul and platelets are greater than 50,000 cells/ul.

Treatment repeats every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients who achieve remission (significant reduction in the amount of leukemia in bone marrow and blood/MRD negative) after 4 cycles may receive alternative treatment, either consolidation with two cycles of Hyper-CVAD followed by TKI maintenance therapy or undergo allogeneic stem cell transplantation followed by maintenance therapy. Patients who do not achieve a remission (MRD positive) are assigned to Arm D. Patients who experience un-resolving renal failure or life-threatening infection which may require a treatment delay of 21 days cross-over to Arm C to receive the prescribed course of blinatumomab.

ARM C (INDUCTION THERAPY):

CYCLE 1: Patients receive ponatinib PO QD or dasatinib PO QD on days 1-28. Patients also receive dexamethasone PO or IV on day 1 and blinatumomab IV continuously on days 1-28, followed by methotrexate IT on day 29 or 30.

CYCLE 2: Patients receive ponatinib PO QD or dasatinib PO QD on days 1-28. Patients also receive dexamethasone PO or IV on day 1 and blinatumomab IV continuously on days 1-28.

Treatment repeats every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity.

ARM D (RE-INDUCTION): Patients treated on Arm B who remain MRD positive at the end of induction therapy receive blinatumomab based re-induction identical to the regimen described for Arm C.

ARM E (RE-INDUCTION): Patients treated on Arm C who remain MRD positive at the end of induction therapy receive chemotherapy based re-induction which is identical to regimen described for Arm B according to patient's age and the pre-specified chemotherapy arm.

Patients whose molecular test remains MRD positive after re-induction proceed to follow-up at the discretion of the investigator or receive anti CD-19 CAR- T cell therapy, inotuzumab ozogamicin, intensive chemotherapy, or palliative care.

Patients are followed up every 3 months for first 2 years (from study registration), every 6 months for years 3-5, and then every 12 months for years 6-10.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall survival (OS)	Will compare OS following induction with steroids + tyrosine kinase inhibitor (TKI) + blinatumomab and induction with steroids + TKI + chemotherapy. Will be based on an intent-to-treat analysis. Estimates of OS including medians and confidence intervals, will be calculated using the Kaplan-Meier method. Comparisons of OS between treatment arms will be conducted using the one-sided stratified log-rank test with steroid responsiveness, type of TKI intended to receive and age at diagnosis, the same factors used in randomization, as stratification factors. Cox proportional hazards models of OS, stratified on the same factors used in the randomization, will be used to assess the effect of treatment by adjusting other possible clinical and biological risk factors, including cytogenetic abnormalities.	Time between randomization and death from any cause, assessed up to 10 years from the date of registration
Secondary	Rate of minimal residual disease (MRD) negativity	Will be centrally evaluated. Will be compared between two arms using Fisher's exact test with a one-sided type I error rate of 2.5%. Multivariable logistic regression modeling will be used to adjust for other possible clinical and biological risk factors. For patients registered to Step 3 (re-induction), the rates of MRD negativity and their corresponding 95% confidence intervals after re-induction will be given by treatment arm.	At week 15
Secondary	Event free survival (EFS)	Will be based on an intent-to-treat analysis. Estimates of EFS including medians and confidence intervals, will be calculated using the Kaplan-Meier method. Comparisons of EFS between treatment arms will be conducted using the one-sided stratified log-rank test with steroid responsiveness, type of TKI intended to receive and age at diagnosis, the same factors used in randomization, as stratification factors. Cox proportional hazards models of EFS, stratified on the same factors used in the randomization, will be used to assess the effect of treatment by adjusting other possible clinical and biological risk factors, including cytogenetic abnormalities	Time from randomization to failure to achieve induction molecular remission by week 15, confirmed molecular relapse after molecular remission or to death in remission, assessed up to 10 years from the date of registration
Secondary	Rate of MRD negativity	Will be centrally evaluated. Will be compared between two arms using Fisher's exact test with a one-sided type I error rate of 2.5%. Multivariable logistic regression modeling will be used to adjust for other possible clinical and biological risk factors. For patients registered to Step 3 (re-induction), the rates of MRD negativity and their corresponding 95% confidence intervals after re-induction will be given by treatment arm.	After re-induction
Secondary	Incidence of adverse events	All toxicity grades and reportable adverse events will be graded using the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.	Up to 10 years from the date of registration
