Inclusion criteria

Aged 18-70 years (inclusive)，gender not limited.
Pathologically diagnosed, relapsed or refractory peripheral T-cell lymphoma.
Disease status defined as relapsed or refractory after >=1 prior systemic treatment lines, and have not received treatment with HDAC inhibitors, subjects with NK/T-cell lymphoma require treatment with a regimen containing asparaginase/protease, subjects with CD30 positive ALCL require prior treatment with Brentuximab vedotin.
Subjects who have received prior radiotherapy are allowed to enroll, but radiotherapy alone is not considered a systemic therapy.
Having at least one measurable lesion for evaluation.
Agree to provide archived tumor tissue samples or fresh tumor tissue samples that meet the requirements.
Life expectancy of at least 12 weeks.
Subjects must have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) Performance Scale.
Have adequate organ function.
Females of childbearing potential must have a negative pregnancy test within 7 days prior to the first dose of study drug. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test is required.Non-sterile subjects must be willing to use a highly effective contraception (e.g., IUD, pill, or condom) for the duration of the study and for 6 months after the last dose of study drug unless their partner is sterilized. For male subjects whose partner is a woman of childbearing potential, surgical sterilization or agreement to use effective contraception for the duration of the study and for 6 months after the last dose of study drug is required. In addition, males must agree not to donate sperm during the study participation and for at least 6 months after the last dose of study drug.
Able to provide written informed consent form prior to the commencement of any study activity/procedure.

Exclusion criteria

Prior exposure to EZH2 inhibitor(s) or EZH1/2 inhibitor(s).
Prior exposure to HDAC inhibitor(s).
Subjects with known hypersensitivity to the study drug or its active ingredients or excipients.
Subjects who have received anti-tumor therapy, such as chemotherapy, immunotherapy, radiotherapy, and targeted therapy, within 4 weeks or 5 half-lives (whichever is shorter) before the first dose of the study drug, received CAR-T therapy within 12 weeks prior to the first dose of the study drug, autologous hematopoietic stem cell transplantation (Auto-HSCT) within 3 months prior to the first dose of the study drug.
Subjects who have received other anti-tumor investigational drug treatment within 28 days prior to the first dose of XNW5004 in this study.
Subjects who have undergone major surgery within 4 weeks prior to the start of study treatment or who intend to undergo major surgery during this study (except for procedures such as puncture or lymph node biopsy).
Subjects who have an allogeneic hematopoietic stem cell transplantation or solid organ transplantation.
Subjects who have received systemic treatment with corticosteroids (prednisone at a dose of > 10 mg per day or equivalent doses of other glucocorticoids) or other immunosuppressive drugs within 14 days prior to the use of the study drug. In the absence of active autoimmune disease, inhaled or topical steroids and adrenal replacement therapy with prednisone at a dose of ≤ 10 mg per day or equivalent doses of other glucocorticoids are permitted.
Subjects taking known strong CYP3A4 inhibitors/inducers and P-glycoprotein (P-gp) inhibitors within 14 days prior to the first dose.
Subjects who have received live virus vaccines (including live attenuated vaccines) within 28 days prior to dosing. Inactivated vaccines are permitted.
Subjects with a history of psychotropic drug abuse or drug abuse.
Subjects who have received anti-tumor therapy in the early stage and have not recovered from toxicity (toxicity has not recovered to ≤ Grade 1 according to NCI-CTCAE 5.0). Except for other toxicities (such as alopecia, etc.) that do not affect the safety evaluation of subjects in the opinion of the investigator.
Subjects with history of other malignancies within 3 years prior to enrollment and not meeting clinical cure criteria. Exceptions are the following: cured basal cell or squamous cell carcinoma of the skin, superficial bladder cancer, carcinoma in situ of the cervix, intraductal carcinoma in situ of the breast, and papillary carcinoma of the thyroid that can be treated locally.

Subjects with previous or current acute myeloid leukemia (AML).
Subjects with previous or current T-cell lymphoblastic lymphoma (T-LBL) or T-lymphoblastic leukemia.
Subjects who have any history of myeloid malignancy, including myelodysplastic syndrome (MDS), or abnormal tests results of markers related to MDS or myeloproliferative neoplasm (MPN).
Subjects who previously hadcentral nervous system lesions, or diseases accompanies with central nervous system lesions, including but not limited to, epilepsy, paralysis, stroke, severe brain injury, Alzheimer's disease, Parkinson's disease, cerebellar disease, cerebral organic syndrome, or psychosis, etc.
Subjects with clinically significant cardiovascular disease.
Tumor invasion of important peripheral organs and blood vessels (such as heart and pericardium, trachea, esophagus, aorta, superior vena cava, etc.) posing a risk of bleeding or the risk of esophageal tracheal fistula or esophageal pleural fistula.
