PI3Kδ Inhibitor Linperlisib Combined With HDAC Inhibitor Chidamide Versus CHOP in Patients With Peripheral T-cell Lymphoma: a Multicenter, Open Label, Phase Ib/II Study
The goal of this clinical trial is to determine the maximum tolerated dose (MTD) of PI3Kδ inhibitor linperlisib when combined with fixed dose of HDAC inhibitor chidamide in participants with peripheral T-cell lymphoma (PTCL), and to compare the combination of linperlisib and chidamide to standard CHOP (cyclophosphamide, doxorubicin/epirubicin, vincristine, and prednisone) regimen chemotherapy in the frontline treatment of PTCL to see which therapy is better.
• Age 18-75 years at the time of inclusion (Age 18-80 years for phase Ib study)
• Patients with a newly diagnosed and histologically confirmed PTCL (phase Ib study includes both newly diagnosed and relapsed/refractory PTCL). Anaplastic large cell lymphoma and NK/T-cell lymphoma are not included.
• ECOG PS 0-2 at protocol entry
• Estimated life expectancy of 6 months or longer
• Measurable disease
• Hemoglobin ≥ 8 g/dL (≥5 mmol/l); Platelets ≥ 75 x 10E9/L; Absolute neutrophil count ≥ 1.0 x 10E9/L; Platelets ≥ 50 x 10E9/L permitted if documented bone marrow involvement; Serum bilirubin ≤ 1.5 x upper limit of normal (ULN); Serum glutamic-oxaloacetic transaminase (AST) and/or serum glutamic-pyruvic transaminase (ALT) ≤ 2.5 x ULN, or ≤ 5 x ULN if elevation is due to hepatic involvement by lymphoma; Serum creatinine ≤ 1.5 x ULNb; left ventricular ejection fraction (LVEF) ≥ 50%
• Women of childbearing potential must use safe anticonception (e.g. contraceptive pills, intrauterine devices etc.) during the study and 12 months after the last administration of study drugs; Male patients must use contraception for the duration of the study and 6 months after the last administration of study drugs if his partner is of childbearing potential
