Patients are in 2 cohorts:
Cohort 1: dexamethasone, methotrexate, ifosfamide, pegaspargase, and etoposide (modified SMILE) chemotherapy regimen alone and pembrolizumab in children, adolescents, and young adults with advanced stage NK lymphoma and leukemia Cohort 2: combining pralatrexate (PRX) (Cycles 1, 2, 4, 6) and brentuximab vedotin (BV) (Cycles 3, 5) to cyclophosphamide, doxorubicin, and prednisone in children, adolescent, and young adults with advanced peripheral T-cell lymphoma (non-anaplastic large cell lymphoma or non-NK lymphoma/leukemia) .
Both groups proceed to allogeneic stem cell transplant with disease response.

Chemotherapy Regimen: mSMILE: Methotrexate Day 1, Ifosfamide Days 2-4, Dexamethasone Days 2-4, Etoposide Days 2-4, calaspargase pegol Day 8. For patients in CR and no available allogeneic SCT can receive up to 2 additional cycles of mSMILE. Pembrolizumab: For patients in PR/MR/NR/PD after 2 cycles of mSMILE. Allogeneic Stem Cell Transplant if donor available and not in PD. |
