3. ECOG PS 0,1 or 2.
4. Participants with histologically proven peripheral T-cell lymphoma with T-follicular helper phenotype (PTCL-TFH), including: a. angioimmunoblastic T-cell lymphoma, b. follicular helper T-cell lymphoma, follicular type, c. follicular helper T-cell lymphoma, NOS.
5. At least one measurable disease according to the Lugano 2014 Classification.
6. Laboratory criteria are as follows except that caused by lymphoma assessed by the investigator (without receiving any supportive treatment for the following parameters within 2 weeks from the last dose prior to study entry):

(1)Hematology values:Hemoglobin (Hb)≥90g/L,Absolute neutrophil count (ANC) ≥1.5×10 9/L, platelets ≥90×10 9/L (2)Biochemical values: Serum creatinine ≤1.5×upper limit of normal(ULN),Total bilirubin ≤1.5 × ULN, Alanine aminotransferase (ALT), Aspartate aminotransferase (AST) ≤2.5×ULN(ALT, AST≦5×ULN if liver involved).

7.Expected survival≥6 months.

Exclusion Criteria

1. Presence of CNS involvement.
2. Received prior therapies targeting lymphoma.
3. Participants planned for autologous or allogeneic transplant as consolidation after CR.
4. Participants with any other malignancy in past 5 years, except for local tumors that have been cured.
5. Prior treatment with cytotoxic drugs for another condition (e.g., rheumatoid arthritis).
6. Any investigational therapy within 3 months.
7. Contraindication to any of the individual components of CHOP.
8. Corticosteroid use > 30 mg/day of prednisone or equivalent, for purposes other than lymphoma symptom control, and the following conditions for inclusion must be met, a. participants receiving corticosteroid treatment with ≤ 30 mg/day of prednisone or equivalent must be documented to be on a stable dose of at least 4 weeks' duration prior to randomization, b. If glucocorticoid treatment is urgently required for lymphoma symptom control prior to the start of study treatment, prednisone 100 mg or equivalent could be given for a maximum of 7 days, but all tumor assessments must be completed prior to start of glucocorticoid treatment.
9. Ongoing serious central nervous system disease or peripheral neuropathy, such as progressive multifocal leukoencephalopathy.
10. Have uncontrolled or significant cardiovascular disease, including a. Grade Ⅱ or higher Congestive heart failure, unstable angina pectoris, myocardial infarction (New York Heart Association Functional Classification ) within 6 months prior to study entry; or arrhythmia requiring treatment, or Left Ventricular Ejection Fraction (LVEF) < 50% during screening stage b.Primary cardiomyopathy (dilated cardiomyopathy, hypertrophic cardiomyocyte, arrhythmogenic right ventricular cardiomyopathy, restrictive cardiomyopathy, et,al) c.History of significant QT interval prolongation, or Corrected QT Interval QTc≥450ms(male), QTc≥470ms（female）at screening d.Symptomatic coronary heart disease requiring treatment e.Any other cardiovascular disease which is inappropriate for the study according to investigators' judgment.
11. History of interstitial lung disease(ILD), or with ongoing signs and symptoms by CT or MRI at the time of screening.
12. Participants with factors that could affect oral medication (such as dysphagia, chronic diarrhea, intestinal obstruction etc), or undergone gastrectomy.
13. History of deep vein thrombosis or pulmonary embolism.
14. History of active bleeding within 2 months prior to the start of Cycle 1;or participants receiving anticoagulation therapy; or participants with evidence of bleeding potential according to investigators' judgment ( esophageal varices, active ulcer, or fecal occult blood test positive etc. ). participants with bleeding led by lymphoma according to investigators' judgment are eligible.
