Summary

COPGEM (Copanlisib and Gemcitabine)chemotherapy regimen is proposed as the salvage treatment for relapsed or refractory peripheral T-cell or NK/T-cell lymphomas in this study protocol, which would be expected to be feasible and effective in this group of patients.

Copanlisib (BAY 80-6946), a highly selective and potent class-1 PI3K inhibitor with sub-nanomolar IC50s against PI3Kα and PI3Kδ, has demonstrated activity in relapsed/refractory, aggressive NHLs, suggesting an ORR of 50% for T-cell lymphomas.

Gemcitabine has demonstrated clinical antitumor activity against PTCLs including NK/T-cell lymphomas both as single-agent (ORR 30-50%) and in combination therapy, with limited extramedullary toxicities.

Considering the evidence of activity for both agents against PTCLs, the investigators propose that targeted therapy with copanlisib in combination with gemcitabine will exhibit early elimination of rapidly growing tumor cells and be a rational therapeutic modality for use in relapsed or refractory PTCLs, if the overlapping toxicities can be managed.

Conditions

  • Mature T-Cell and NK-Cell Neoplasm

Interventions

DRUG

Copanlisib

For phase I study, participants will receive copanlisib (in combination with gemcitabine) IV infusion at a dose of 45 mg or 60 mg on Days 1, 8, and 15 of each 28-day treatment cycle. During phase I study, participants will be treated at the level of 45 mg/dose (level+0), or 60 mg/dose (level+1) of copanlisib. Maximal tolerated dose will be determined by modified 3+3 design including level-1 dose de-escalation. For phase II study, copanlisib dose level, determined during phase I study, will be administered on Days 1, 8, and 15. Maximum 6 cycles of gemcitabine and copanlisib combination and subsequent copanlisib monotherapy in participants with ≥ SD to copanlisib and gemcitabine until maximum 12 cycles will be given for this study.

DRUG

Gemcitabine

For phase I/II study, participants will receive gemcitabine (in combination with copanlisib) IV infusion at fixed dose of 1,000 mg/m2 on Days 1 and 8 of each 28-day treatment cycle until maximum 6 cycles.
