Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
I. Determine the efficacy of duvelisib maintenance therapy in peripheral T-cell lymphoma (PTCL) patients who have achieved a complete response (CR) following first-line treatment and are either ineligible for or decline consolidative autologous stem cell transplantation (ASCT).
SECONDARY OBJECTIVE:
I. Determine the tolerability and preliminary survival outcomes of duvelisib maintenance therapy.
EXPLORATORY OBJECTIVE:
I. Examine the association between biomarkers (e.g., minimal residual disease \[MRD\]) and clinical outcomes (overall response rate \[ORR\], progression free survival \[PFS\]).
OUTLINE:
Patients receive duvelisib orally (PO) twice daily (BID) on days 1-28 of each cycle. Cycles repeat every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients who remain in continuous complete response may continue to receive duvelisib for an additional 13 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow aspiration and biopsy during screening, as well as positron emission tomography (PET)/computed tomography (CT) scans and blood sample collection throughout the study. Patients may also undergo bone marrow aspiration and biopsy on study.
After completion of study treatment, patients are followed up at 4-6 weeks, then periodically for up to 5 years.

Treatment (duvelisib)
Patients receive duvelisib PO BID on days 1-28 of each cycle. Cycles repeat every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients who remain in continuous complete response may continue to receive duvelisib for an additional 13 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow aspiration and biopsy during screening, as well as PET/CT scans and blood sample collection throughout the study. Patients may also undergo bone marrow aspiration and biopsy on study.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Assent, when appropriate, will be obtained per institutional guidelines
* Age: ≥ 18 years
* Eastern Cooperative Oncology Group (ECOG) ≤ 2
* Histologically confirmed nodal T-follicular helper (TFH) cell lymphomas or PTCL-not otherwise specified (NOS). Nodal TFH cell lymphomas encompass three subtypes:
* Angioimmunoblastic T-cell lymphoma (AITL)(World Health Organization 4th edition revised \[WHO4R\])/follicular helper T-cell lymphoma (TFH lymphoma), angioimmunoblastic type (International Consensus Classification \[ICC\])/nodal TFH cell lymphoma, angioimmunoblastic-type (World Health Organization 5th edition \[WHO5\])
* Nodal PTCL with TFH phenotype (nodal PTCL, TFH)(WHO4R)/TFH lymphoma, NOS (ICC)/nodal TFH cell lymphoma, NOS (WHO5)
* Follicular T-cell lymphoma (FTCL)(WHO4R)/TFH lymphoma, follicular type (ICC)/ nodal TFH cell lymphoma, follicular-type (WHO5)
* Completion of first-line multi-agent chemotherapy with a cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP)-based regimen and documentation of complete response (CR) per Lugano criteria within the previous 6 months prior to enrollment. Prior corticosteroid monotherapy is not considered a line of therapy
* Ineligible for or decline consolidative autologous stem cell transplantation. Ineligibility is defined by:
* Patient deemed ineligible for high-dose chemotherapy and ASCT based on physician's assessment
* AND at least one of the following criteria:
* Age ≥ 65 years or
* Age ≥ 18 years and Hematopoietic Cell Transplantation-specific Comorbidity Index score ≥ 3
* Recovery to ≤ grade 1 or baseline for any toxicities due to prior treatments, with the exception of peripheral neuropathy (recovery to ≤ grade 2) or alopecia
* Platelets ≥ 25,000/mm\^3
* Hemoglobin ≥ 8 g/dL
* CD4 lymphocyte count ≥ 50/mm\^3 (0.05 × 10\^9/L)
* Total bilirubin ≤ 1.5 × upper limit of normal (ULN) (in patients with Gilbert's Syndrome a bilirubin \> 1.5 × ULN but ≤ 3 × ULN may be allowed with sponsor approval)
* Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase \[SGOT\]) ≤ 2.5 × ULN
* Alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase \[SGPT\]) ≤ 2.5 × ULN
* Serum creatinine ≤ 2.0 × ULN or creatinine clearance ≥ 30 mL/min (estimated by Chronic Kidney Disease Epidemiology Collaboration \[CKD-EPI\] or Cockcroft-Gault equation or measured)
* Seronegative for HIV antigen (Ag)/antibody (Ab) combo, hepatitis C virus (HCV), active hepatitis B virus (HBV) (surface antigen negative) OR patients with presence of hepatitis B core antibody (HBcAb), but absence of hepatitis B surface antigen (HBsAg), are eligible if hepatitis B virus (HBV) deoxyribonucleic acid (DNA) is undetectable (\< 20 IU), and if they are willing to undergo monitoring every 4 weeks for HBV reactivation. Patients positive for HCV antibody are eligible only if polymerase chain reaction (PCR) is negative for HCV ribonucleic acid (RNA)
