Brief Summary

This phase II clinical trial tests a chemotherapy regimen (dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin with or without rituximab \[DA-EPOCH+/-R\]) with the addition of targeted therapy (tafasitamab) for the treatment of patients with newly diagnosed Philadelphia chromosome negative (Ph-) B acute lymphoblastic leukemia (B-ALL). Chemotherapy drugs, such as those in EPOCH+/-R, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Tafasitamab is in a class of medications called monoclonal antibodies. It works by helping the body to slow or stop the growth of cancer cells. Adding tafasitamab to the DA-EPOCH+/-R regimen may work better than DA-EPOCH+/-R alone in treating newly diagnosed Ph- B-ALL.

Conditions

B Acute Lymphoblastic Leukemia, Philadelphia Chromosome Negative

Outcome Measures

Primary Outcomes (1)

• Rate of minimal residual disease (MRD)

  Efficacy of the addition of tafasitamab (tafa) to dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin with our without rituximab (DA-EPOCH±R) will be assessed using the rate of minimal residual disease (MRD) as measured by multiparameter flow cytometry (MFC) in the University of Washington hematopathology lab. Will consider an absolute increase in the rate of MRD- after one cycle to 50% to be a signal of interest (i.e., increase from 28%).

  After 1 cycle of treatment (each cycle = 21 days)

Secondary Outcomes (5)

• Rate of MRD

  After 4 cycles of treatment (each cycle = 21 days)

• Incidence of adverse events

  Up to 5 years

• Event-free survival (EFS)

  Up to 5 years

• Relapse-free survival (RFS)

  Up to 5 years

• Overall survival (OS)

  Up to 5 years

Treatment (DA-EPOCH+/-R, tafasitamab)

EXPERIMENTAL

Patients receive etoposide, doxorubicin, and vincristine IV continuously over 96 hours on days 1-4 of each cycle, cyclophosphamide IV over 1 hour on day 5 of each cycle, prednisone PO BID on days 1-5 of each cycle, and tafasitamab IV weekly on days 1, 8, and 15 of each cycle. CD20 positive patients also receive rituximab IV per guidelines on days 1 or 5 of each cycle. Treatment repeats every 21 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow aspiration or biopsy, CT scan, lumbar puncture and undergo blood sample and cerebrospinal fluid collection throughout the trial.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Adults (age 18 years and older) with newly-diagnosed CD19+ Ph- B-ALL
• In the opinion of the treating investigator, patients must be an unsuitable candidate for a pediatric-inspired regimen, reasons for which may include (but not be limited to) older age (e.g., \>= 40 years), practical/logistical barriers to or toxicity concerns from administration of a pediatric-inspired regimen
• Marrow or blood involvement detectable by MFC
• Total bilirubin =\< 2.0 x upper limit of normal (ULN) (unless attributed to Gilbert's disease or other causes of inherited indirect hyperbilirubinemia, at which point total bilirubin must be =\< 4.0 x ULN)
• Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 5.0 x institutional ULN. (Note: Patients with liver test abnormalities attributable to hepatic involvement by ALL will be permitted if the total bilirubin is =\< 5.0 x ULN and ALT/AST are =\< 8.0 x ULN)
• Calculated creatinine clearance of \> 30 ml/min, as measured by the Modification of Diet in Renal Disease (MDRD) equation, will be eligible
• As patients with ALL frequently have cytopenias, no hematologic parameters will be required for enrollment or to receive the first cycle of treatment. However, adequate recovery of blood counts will be required to receive subsequent cycles
• Eastern Cooperative Oncology Group (ECOG) performance status 0 to 2. (Performance status of 3 will be allowed if poor performance status is thought to be directly secondary to ALL)
• Ability to give informed consent and comply with the protocol
• Anticipated survival of at least 3 months, independent of ALL

You may not qualify if:

• Burkitt lymphoma/leukemia
• No prior systemic therapy for ALL except to control acute symptoms and/or hyperleukocytosis (e.g., corticosteroids, cytarabine, etc.)
• No isolated extramedullary or known parenchymal central nervous system (CNS) disease
• Known hypersensitivity or intolerance to any of the agents under investigation
• Other medical or psychiatric conditions that in the opinion of the investigator would preclude safe participation in the protocol
• May not be pregnant or nursing
• Pregnancy test is only required in women, unless they are highly unlikely to conceive (defined as \[1\] surgically sterilized, or \[2\] postmenopausal \[i.e., a woman who is \> 50 years old or who has not had menses for \>=1 year\], or \[3\] not heterosexually active)
