This phase II trial studies the effect of adding duvelisib or CC-486 to the usual chemotherapy consisting of cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone vs. chemotherapy alone in treating patients with peripheral T-cell lymphoma. Duvelisib is in a class of medications called kinase inhibitors. It works by blocking the signals that cause cancer cells to multiply. This helps to stop the spread of cancer cells. Chemotherapy drugs, such as CC-486, cyclophosphamide, doxorubicin, vincristine, etoposide, 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. Prednisone is used to reduce inflammation and lower the body's immune response to help reduce the side effects of chemotherapy drugs. This trial will help to determine whether adding duvelisib or CC-486 to the usual chemotherapy is better than chemotherapy alone in treating peripheral T-cell lymphoma.


I. To compare the complete remission (CR) rates by fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) using the Lugano 2014 criteria following completion of treatment with duvelisib-cyclophosphamide (C) doxorubicin (H) vincristine (O) (etoposide [E]) prednisone (P) versus (vs) CHO(E)P and with CC-486-CHO(E)P vs CHO(E)P in previously untreated peripheral T-cell lymphomas that have < 10% expression of CD30.

I. To determine the toxicity and tolerability of the treatment regimens.
II. To determine the CR rates by FDG PET/CT or CT alone using the Lugano 2014 criteria.
III. To determine the overall response rate (ORR), duration of response, progression free survival (PFS), event free survival (EFS), and overall survival (OS) of each treatment regimen.
IV. To determine whether designation of follicular helper T-cell phenotype is correlated with response to therapy, PFS, EFS, and OS.
V. To assess the toxicity profile of the experimental regimens in untreated CD30 negative peripheral T-cell lymphomas using Common Terminology Criteria for Adverse Events (CTCAE) and patient reported outcomes (PRO)-CTCAE.

OUTLINE: Patients are randomized to 1 of 3 arms.

ARM A: Patients receive cyclophosphamide intravenously (IV) on day 1, doxorubicin IV on day 1, vincristine IV on day 1, etoposide (given only to patients =< 60 years old) IV on day 1 or days 1-3 or orally (PO) once daily (QD) on days 2-3, and prednisone PO QD on days 1-5. Patients also receive duvelisib PO twice daily (BID) on days 1-21. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive cyclophosphamide IV on day 1, doxorubicin IV on day 1, vincristine IV on day 1, etoposide (given only to patients =< 60 years old) IV on day 1 or days 1-3 or PO QD on days 2-3, and prednisone PO QD on days 1-5. Patients also receive CC-486 PO QD on days -6 to 0 of cycle -1 and days 8-21 of cycles 1-5. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

ARM C: Patients receive cyclophosphamide IV on day 1, doxorubicin IV on day 1, vincristine IV on day 1, etoposide (given only to patients =< 60 years old) IV on day 1 or days 1-3 or PO QD on days 2-3, and prednisone PO QD on days 1-5. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

All patients undergo bone marrow biopsy during screening and on the trial. Patients also undergo positron emission tomography (PET)/ computed tomography (CT) throughout the trial. Additionally, patients undergo blood sample collection on the trial and during follow up.

After completion of study treatment, patients are followed up every 12 weeks for 2 years, every 24 weeks until 5 years or until documented progression of lymphoma. After documented progression of lymphoma, patients are followed up every 6 months until 5 years from end of treatment.


  1. Histologically confirmed diagnosis of peripheral T-cell lymphoma (PTCL) with < 10% CD30 expression by immunohistochemistry in the following subtypes: nodal T-cell lymphoma with T-follicular helper (TFH) phenotype (TFH-PTCL), follicular T-cell lymphoma, PTCL-not otherwise specified (NOS), angioimmunoblastic T-cell lymphoma (AITL), enteropathy associated T-cell lymphoma, monomorphic epitheliotropic intestinal T-cell lymphoma * Patients with expression of CD30 in >= 10% of the tumor (based on local immunohistochemistry review) regardless of histology will not be permitted * Patients with a diagnosis of other PTCL subtype histologies other than those specified in the inclusion criteria are excluded including large cell transformation of mycosis fungoides * Patients will be stratified by presence or absence of TFH phenotype (i.e. diagnosis of AITL, TFH-PTCL, follicular T-cell lymphoma) based on local review of pathology. Determination of TFH phenotype can be defined by expression of two or more of the following markers CD10, BCL6, CXCL13, ICOS, and PD1 by immunohistochemistry
