Dose-Adjusted Etoposide, Prednisone, Vincristine, Cyclophosphamide, and Doxorubicin (DA-EPOCH) ± Rituximab + Recombinant Erwinia Asparaginase (JZP458; Rylaze®) for the Treatment of Newly-Diagnosed Adults With Philadelphia Chromosome-Negative Acute Lymphoblastic Lymphoma/Leukemia

Intervention Type: Drug, Biological, Procedure
Study Type: Interventional
Study Phase: Phase 2
SUMMARY

This phase II trial tests how well etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin (DA-EPOCH) with or without rituximab plus recombinant Erwinia asparaginase (JZP458) works in treating patients with newly diagnosed Philadelphia chromosome (Ph) negative B-acute lymphoblastic leukemia (ALL) or T-ALL. Chemotherapy drugs, such as etoposide, vincristine, cyclophosphamide and doxorubicin, 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. Anti-inflammatory drugs, such as prednisone, lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. JZP458 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving DA-EPOCH with or without rituximab plus JZP458 may kill more cancer cells in patients with newly diagnosed Ph negative B-ALL or T-ALL.

Eligibility
Participation Requirements
Sex: All
Minimum Age: 18
Healthy Volunteers: f
View:

• Adults (age 18 years and older) with newly-diagnosed Ph- B-ALL or T-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 by ALL detectable by multi-parameter flow cytometry (MFC)

• 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.)

• 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) (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 alanine aminotransferase \[ALT\]/aspartate aminotransferase \[AST\] are ≤ 8.0 x ULN.)

• AST (serum glutamic oxaloacetic transaminase \[SGOT\])/ALT (serum glutamic pyruvic 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 ≥ 60 ml/min/1.73 m\^2, 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

• Ability to give informed consent and comply with the protocol

• Anticipated survival of at least 3 months, independent of ALL

• Female subjects of childbearing potential should use effective non-hormonal contraceptive methods during treatment with JZP458 and for 3 months after the last dose of study drug. Male subjects with female partners of childbearing potential must agree to use an effective method of birth control from the time of signing the consent form until at least 3 months after the last dose of study drug

Participants
Target number of participants: 30
Treatments
Experimental: Treatment (DA-EPOCH, rituximab, JZP458)
Patients receive etoposide IV, doxorubicin IV and vincristine IV over 96 hours on days 1-4, cyclophosphamide IV over 1 hour on day 5, prednisone PO BID on days 1-5 of each cycle. In addition, CD20 positive patients receive rituximab IV on day 1 or 5 of each cycle. Patients also receive JZP458 IM every 2-3 days on days 7-21 for up to 7 doses. Cycles repeat every 21 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity. Starting on day 6, 7, or 8, patients also receive pegfilgrastim SC once or filgrastim SC QD until ANC \> 2000/uL past nadir. Patients also undergo blood sample collection and bone marrow collection throughout the study. Additionally, patients with extramedullary disease may undergo CT or PET/CT throughout the study.
