Clinical Trial of Chidamide Combined With CHOP in Peripheral T-cell Lymphoma Patients

The purpose of this study is to assess the tolerability and safety include adverse events, vital signs, laboratory tests, etc., of a range of doses of chidamide combined with CHOP in peripheral T-cell lymphoma patients, and to determine the dose limit toxicity and the maximum tolerable dose.
