Summary

This study includes Phase I and Phase II stages. Phase I is an open-label trial to confirm RP2D of oral targeted agents in three genetic subtypes. Phase II is a multicenter, prospective, randomized, open-label, controlled trial to evaluate the efficacy and safety of genotype-guided targeted agents plus cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP-X2) versus cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in patients with peripheral T-cell lymphoma.

Detailed description

Peripheral T-cell lymphoma (PTCL) is a heterogeneous disease with dismal outcomes. Standard CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) chemotherapy is still the most widely used front-line treatment of PTCL except Brentuximab-CHP application in anaplastic large cell lymphoma (ALCL). The CR rate ranges from 31%-56% in different studies with different PTCL histology compositions. With the exception for ALCL-anaplastic lymphoma kinase (ALK)-positive, the 5-year overall survival (OS) rate is approximately 30%-40% for most subtypes of PTCL patients in current situation, remaining as the unmet medical needs in this disease. Based on genetic subtypes in PTCL, and our previous study exploring targeted agents plus CHOP based on genetic mutations (Guidance-03 study), we conducted this multicenter, prospective, randomized, open-label, controlled trial to evaluate the efficacy and safety of genotype-guided targeted agents plus CHOP (CHOP-X2) versus cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in patients with PTCL. It includes phase I and phase II stages. Patients will receceived stardard CHOP for the first cycle and then obtain the genetic subtypes from tumor NGS befor Cycle 2. In phase I, recommended phase 2 dose (RP2D) of oral targeted agents will be confirmed by traditional "3+3" dose escalation methods. In phase II, patients will receive standard CHOP for the first cycle and then 1:1 be randomized to CHOPX2 or CHOP regimen in each genetic subtypes.

Conditions

• Peripheral T Cell Lymphoma

Interventions

Type	Name	Description
DRUG	CHOP+selinexor+5-Azacitidine	Phase I: Patients in this arm will receive cyclophosphamide 750 mg/m² IV, doxorubicin 50 mg/m² IV, and vincristine 1.4 mg/m² IV (maximum 2 mg) on day 1, and prednisone 100 mg/day PO on days 1-5 of every 21-day cycle for the first cycle. If tumor NGS indicates T1 genetic subtype, for the remaining 5 cycles, they will receive 5-Azacitidine ih d-7-d-1 and selinexor 40mg or 60mg qw (d-7, 1, 8) by traditional "3+3" dose escalation methods and decide RP2D of selinexor. Phase II: Patients will receive CHOP for the first cycle. If tumor NGS indicates T1 genetic subtype, then 1:1 randomized to experimental (CHOPX2) or standard CHOP regimen for 5 cycles of every 21-day cycle.
DRUG	CHOP+duvelisib+5-Azacitidine	Phase I: Patients in this arm will receive cyclophosphamide 750 mg/m² IV, doxorubicin 50 mg/m² IV, and vincristine 1.4 mg/m² IV (maximum 2 mg) on day 1, and prednisone 100 mg/day PO on days 1-5 of every 21-day cycle for the first cycle. If tumor NGS indicates T2 genetic subtype, for the remaining 5 cycles, they will receive 5-Azacitidine ih d-7-d-1 and duvelisib 25mg or 50mg bid (d1-14) by traditional "3+3" dose escalation methods and decide RP2D of duvelisib. Phase II: Patients will receive CHOP for the first cycle. If tumor NGS indicates T1 genetic subtype, then 1:1 randomized to experimental (CHOPX2) or standard CHOP regimen for 5 cycles of every 21-day cycle.
DRUG	CHOP+chidamide+tislelizumab	Phase I: Patients in this arm will receive cyclophosphamide 750 mg/m² IV, doxorubicin 50 mg/m² IV, and vincristine 1.4 mg/m² IV (maximum 2 mg) on day 1, and prednisone 100 mg/day PO on days 1-5 of every 21-day cycle for the first cycle. If tumor NGS indicates T3 genetic subtype, for the remaining 5 cycles, they will receive tislelizumab 200mg d0 ivgtt and chidamide 20mg or 30mg biw (d1,4,8,11) by traditional "3+3" dose escalation methods and decide RP2D of chidamide. Phase II: Patients will receive CHOP for the first cycle. If tumor NGS indicates T3 genetic subtype, then 1:1 randomized to experimental (CHOPX2) or standard CHOP regimen for 5 cycles of every 21-day cycle.
DRUG	standard CHOP	Patients in this arm will receive cyclophosphamide 750 mg/m² IV, doxorubicin 50 mg/m² IV, and vincristine 1.4 mg/m² IV (maximum 2 mg) on day 1, and prednisone 100 mg/day PO on days 1-5 of every 21-day cycle for the 6 cycles.
