This phase II trial studies the effect of duvelisib or CC-486 and usual chemotherapy consisting of cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone in treating patients with peripheral T-cell lymphoma. Duvelisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as CC-486, cyclophosphamide, doxorubicin, vincristine, etoposide and prednisone, 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. This trial may help find out if this approach is better or worse than the usual approach for treating peripheral T-cell lymphoma.
PRIMARY OBJECTIVE: I. To compare the complete remission (CR) rates by positron emission tomography (PET)/computed tomography (CT) following completion of treatment with duvelisib-cyclophosphamide (C) doxorubicin (H) vincristine (O) (etoposide \[E\]) prednisone (P) versus (vs) CHO(E)P and with oral azacitidine (CC-486)-CHO(E)P vs CHO(E)P in previously untreated peripheral T-cell lymphomas that have \< 10% expression of CD30. SECONDARY OBJECTIVES: I. To determine the toxicity and tolerability of the treatment regimens. II. 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. III. To determine whether designation of follicular helper T-cell phenotype is correlated with response to therapy, PFS, EFS, and OS. IV. 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 IV on days 1-3 or etoposide IV on day 1 and orally (PO) once daily (QD) on days 2-3 for patients \<=60 years old, 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 IV on days 1-3 or etoposide IV on day 1 and orally (PO) once daily (QD) on days 2-3 for patients \<=60 years old, 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 IV on days 1-3 or etoposide IV on day 1 and orally (PO) once daily (QD) on days 2-3 for patients \<=60 years old, 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. After completion of study treatment, patients are followed at 6 weeks after cycle 6 day 1, then every 12 weeks for 2 years, then every 24 weeks until 5 years from end of treatment 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.

Complete remission (CR) rate
Defined as the number of patients with complete remission (CR) divided by the total number of patients randomized. Will be measured by fludeoxyglucose F-18 (FDG) positron emission tomography (PET)/computed tomography (CT) at the completion of treatment (at end of treatment) and will be compared between each experimental arm and control arm. Final analyses will use z-scores obtained from a stratified Cochran-Mantel-Haenszel test to compare the CR rates between each experimental arm and control arm. For each treatment arm, CR rates will be estimated with their 95% confidence intervals.
Time frame: Up to 6 months
Incidence of adverse events
Adverse events will be collected and graded according to the National Cancer Institute's (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 criteria. For CTCAE data, the maximum grade for each type of adverse will be recorded for each patient, and described using frequency tables. All-cause adverse events will be summarized as well as treatment-related adverse events.
Time frame: Up to 5 years
Overall response rate (ORR)
Overall response includes complete and partial remissions by FDG PET/CT at the completion of treatment (at end of treatment). ORR will be estimated for each treatment arm and calculated as the number of patients with response divided by the total number of patients randomized. For each treatment arm, ORRs will be estimated with their 95% confidence intervals. ORR at the interim assessment will be summarized in the same manner, and how response changes between the interim and final assessment will be described.
Time frame: Up to 6 months
Duration of response
The Kaplan-Meier method will be used to estimate duration of response for each treatment arm, with 2-year estimates and medians along with their 95% confidence intervals.
Time frame: From first date of complete or partial remission until the earlier of disease progression, death from any cause, or non-protocol lymphoma-directed therapy to treat residual or progressive disease, assessed up to 5 years
Progression-free Survival (PFS)
The Kaplan-Meier method will be used to estimate PFS for each treatment arm, with 2-year PFS estimates and PFS medians along with their 95% confidence intervals.
Time frame: From randomization date until the earlier of disease progression, death from any cause, or non-protocol lymphoma-directed therapy to treat residual or progressive disease, assessed up to 5 years
Event-free Survival (EFS)
The Kaplan-Meier method will be used to estimate event-free survival (EFS) for each treatment arm, with 2-year EFS estimates and EFS medians along with their 95% confidence intervals.
Time frame: From randomization date until earlier of non-protocol lymphoma-directed therapy for any reason (excluding planned consolidative transplant), disease progression, or death from any cause, assessed up to 5 years
Overall Survival (OS)
The Kaplan-Meier method will be used to estimate overall survival (OS) for each treatment arm, with 2-year OS estimates and OS medians along with their 95% confidence intervals.
Time frame: From randomization date until death from any cause, censoring patients alive at the date of last contact, assessed up to 5 years
Correlation of follicular helper T-cell phenotype with response, PFS, EFS and OS
CR rates and ORRs will be estimated with 95% confidence intervals for patients with and without the follicular helper T-cell phenotype, as well for patients with the peripheral T-cell lymphomas (PTCL) genotype.
Time frame: Up to 5 years
Patient reported outcomes (PROs)
Patient reported outcomes (PROs) will be captured using the NCI PRO-CTCAE. Scores (0-4) and maximum score for each PRO-CTCAE item, with and without taking into account whether it is worse than the patient's own baseline score, will be recorded for each patient. PRO-CTCAE data will, at minimum, be analyzed similarly to CTCAE data.
Time frame: Up to 6 months
