  • Histology confirmed by enrolling institution Confirmed diagnosis of acute lymphoblastic leukemia (ALL) by morphology, immunohistochemistry, and/or multiparameter flow cytometry, with confirmation of Philadelphia chromosome positivity (Ph+) by cytogenetic studies (karyotype/FISH), molecular studies (BCRABL1 fusion transcripts), or targeted RNA sequencing
  • No prior therapy for ALL beyond corticosteroids, hydroxyurea, or prophylactic intrathecal/intra-Ommaya chemotherapy Acceptable end-organ function (i.e. not meeting exclusion criteria below)
  • Amenable to practicing an effective method of birth control during treatment and for at least 3 months following treatment on study
  • ECOG performance status 0-2

Exclusion Criteria:

  • Philadelphia chromosome-negative ALL

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Blinatumomab & Concurrent Oral Tyrosine Kinase Inhibitor (TKI)

Arm Description

Patients may receive steroids and hydroxyurea pre-study entry and receive a 7-day steroid prephase before starting TKI therapy. Planned initial TKI is dasatinib 140 mg daily; dasatinib dose may be reduced or TKI may be changed to a different agent under certain conditions. Induction consists of continuous TKI + 24 days of dexamethasone, followed by taper of dexamethasone, with bone marrow aspirate/biopsy (BMA) and CNS prophylaxis at days 22 and 43. Patients achieving morphologic complete response post-induction proceed to consolidation with up to 3 cycles of blinatumomab (28-day cycles, 14 days between cycles) + TKI, with BMA and CNS prophylaxis between cycles. Patients achieving complete molecular response may proceed to maintenance with up to 4 more cycles of blinatumomab (28-day cycles with 28 days between cycles) + TKI, with CNS prophylaxis between cycles and BMA after cycles 5 and 7. Patients can come off study to undergo allogeneic hematopoietic cell transplantation at any time.

Outcomes

Primary Outcome Measures

Proportion of evaluable patients achieving complete molecular response
(MRD negativity by flow cytometry and quantitative PCR of BCR-ABL transcripts) at any time during TKI + corticosteroid induction or consolidation with up to 3 cycles of blinatumomab in combination with TKI.

Secondary Outcome Measures

Frequency, severity, and co-occurrence of treatment-related grade 3-4 toxicities
assessed by NCI CTCAE v5.0 and rates of blinatumomab discontinuation due to toxicity among all patients beginning the consolidation portion of the study on dasatinib. The window for toxicity evaluation for this objective extends from the beginning of consolidation of the study until completion of maintenance or removal from study, whichever is sooner."

Duration of CMR among patients achieving MRD negativity after TKI + corticosteroid induction, followed by 1-3 cycles of blinatumomab in combination with an oral TKI.
Cumulative incidence of morphologic and molecular relapse following consolidative therapy with blinatumomab in combination with an oral TKI
Event-free survival following consolidative therapy with blinatumomab in combination with an oral TKI.
Overall survival following consolidative therapy with blinatumomab in combination with an oral TKI.
The proportion of patients first achieving CMR at any point during induction and proportion of patients not achieving CMR in Part 1 who subsequently achieved CMR at any point during consolidation.

5. Study Description

Brief Summary
The purpose of this study is to test whether blinatumomab in combination with TKI therapy (such as dasatinib) is an effective treatment for people with Ph+ ALL. Researchers want to improve the response to standard-of-care treatment of corticosteroids + TKI therapy by adding the study drug, blinatumomab.
Detailed Description
PRE-PHASE: Patients may receive corticosteroids and/or hydroxyurea at the discretion of the treating physician prior to beginning induction therapy. A seven-day corticosteroid pre-phase, which can include days of corticosteroid receipt prior to protocol registration, will precede initiation of TKI therapy on day 1. Corticosteroid dose and schedule are at the discretion of the investigator during the pre-phase, with dosing caps of prednisone 120 mg/day, dexamethasone 24 mg/day, or biologic equivalents thereof. In the event the treating investigator feels delaying induction therapy (TKI + dexamethasone) would be unsafe (e.g. ALL progressing despite corticosteroids), the patient may proceed to day 1 (begin TKI + dexamethasone) before completion of 7-day pre-phase if investigator feels delay would be unsafe. INDUCTION THERAPY: Induction therapy consists of dexamethasone in combination with TKI. TKI therapy will generally begin with dasatinib 140 mg daily (dose changes or transition to alternative TKI permitted subject to the provisions in the protocol). Patients will receive dexamethasone 10 mg/m2/day (up to 24 mg /day) in single or divided doses, days 1-24. Dexamethasone will be tapered days 25-32 (±3 days for start and end of taper); the TKI will be continued during and following the dexamethasone taper. Recommended CNS prophylaxis consists of intrathecal (IT) or intra-Ommaya (IO) methotrexate 12 mg day 22 and day 43 (±7 days); of note, methotrexate 12 mg is recommended though agent/dosing left to discretion of investigator. Hydrocortisone IT may be given along with methotrexate at the discretion of the investigator. Bone marrow evaluations will be performed on days 22 (±3 days) and day 43 (±3 days) and will include minimal residual disease (MRD) assessment by BCR-ABL1 transcript studies and flow cytometry. Under certain circumstances, the induction period may be extended for up to 21 days with bone marrow studies repeated at that time. CONSOLIDATION THERAPY: Patients in complete response (CR) or CR with incomplete hematologic recovery (CRi) following remission induction, with or without MRD, proceed to consolidation therapy, defined as day 1 of cycle 1 of blinatumomab, within 21 days of day 43 or the date of BMA establishing CR/CRi, whichever is later. TKI will be administered continuously. Patients will begin Blinatumomab 28 mcg/daily IVCI for patients ≥45 kg; patients <45 kg will be treated at a dose of 15 mcg/m2/day, capped at a dose of 28 mcg/day, given for a 28-day cycle, with dose adjustments further subject to the provisions outlined in the protocol. Inpatient admission is recommended for at least days 1-3 of cycle 1 of blinatumomab (≥72 hours from start of infusion). Following each 28-day infusion of blinatumomab, a mandatory period of 14 days off blinatumomab will follow during which bone marrow evaluation will be performed with MRD assessment and CNS prophylaxis will be administered. The consolidation period will consist of 3 cycles of blinatumomab given as such. Patients may come off therapy at any point to undergo allogeneic hematopoietic cell transplantation (alloHCT). MAINTENANCE THERAPY: Patients in complete molecular response (as defined within the protocol) following blinatumomab cycle 3 and not proceeding immediately to alloHCT may proceed to maintenance therapy, defined as day 1 of cycle 4 of blinatumomab, within 28 days of completion of blinatumomab infusion in cycle 3. TKI will be administered continuously. Blinatumomab will be given for up to 4 additional 28-day cycles (cycles 4-7) with a mandatory period of 28 days (±7 days) off blinatumomab between cycles, during which CNS prophylaxis will be administered. Bone marrow evaluation with MRD assessment will be performed after cycles 5 and 7 of blinatumomab. FOLLOW-UP: TKI maintenance is recommended but not required. Further post-remission therapy, if any, at the discretion of the treating physician. Following completion of all required study treatments and assessments, patients enrolled will be followed for long-term survival and relapse outcomes as outlined in the protocol.
