Summary

The study is to investigate the safety, tolerability and efficacy of PI3Kδ inhibitor Parsaclisib in combination with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) in frontline treatment of patients with peripheral T-cell lymphoma (PTCL).

Detailed description

The study is to investigate the safety, tolerability and efficacy of PI3Kδ inhibitor Parsaclisib in combination with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) in frontline treatment of patients with peripheral T-cell lymphoma (PTCL) by conducting in two stages, dose-escalation stage and dose-expansion stage. In dose-escalation stage, patients with treated-naïve PTCL will be assigned to receive sequentially higher doses of parsaclisib range from 10 to 20mg po, qd plus CHOP (21 days per cycle). The dose escalation will follow the classic 3+3 design. The recommended phase 2 dose (RP2D) of parsaclisib will be determined according to the dose-escalation results. In dose-expansion stage, additional patients will be recruited to receive Par-CHOP for the planned 6 cycles or until disease progression, unacceptable drug-related adverse events or starting new anti-lymphoma treatments.

Interventions

Type	Name	Description
DRUG	Parsaclisib	Phase Ib: Parsaclisib is taken orally every day continuously, at approximately the same time every day, without food restriction, once a day. This stage follows the traditional "3+3" model. Parsaclisib is set at 10 mg/day, 15 mg/day, 20 mg/day 3 dose groups, starting from 10 mg/day, each group included 3 subjects. The final dose determined at this stage will be used in the Phase II study. Phase II: Induced treatment: Received the initial dose of Parsaclisib determined in Phase Ib. Maintain treatment: 2.5mg orally every day continuously, once a day until disease progression, death or unacceptable toxicity developments. The maximum treatment time of Parsaclisib is no more than 2 years.
DRUG	CHOP	Cyclophosphamide: 750mg/m2, IV, d1 Doxorubicin: 50mg/m2, IV, d1 Vincristine: 1.4mg/m2, IV, d1 (maximum 2mg) Prednison: 100mg, po, d1-5 21 days per cycle
