Obinutuzumab and ICE Chemotherapy in Refractory/Recurrent CD20+ Mature NHL (O-ICE)

August 7, 2025 updated by: Mitchell Cairo, New York Medical College

Chemoimmunotherapy With Obinutuzumab, Ifosfamide, Carboplatin and Etoposide (O-ICE) in Children, Adolescents and Young Adults With Recurrent Refractory CD20+ Mature B-NHL

The purpose of this study is to determine the safety of administering obinutuzumab as a single agent alone and in combination with ifosfamide, carboplatin, and etoposide (ICE) chemotherapy and determine the response rate of this treatment for children, adolescents and young adults (CAYA) with relapsed CD20 positive B-cell Non-Hodgkin Lymphoma (B-NHL).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Central Nervous System (CNS) Negative
All patients will receive 4 doses of obinutuzumab on days -14, -10, -6 and -2. Patients without CNS involvement will receive one dose of Liposomal cytarabine for CNS prophylaxis on day -13. Dexamethasone will be given for 5 days with each Liposomal cytarabine dose starting one day prior to the Liposomal cytarabine. Dexamethasone 0.15 mg/kg/dose (max 4mg) IV BID will be given days -14 to -10. Following completion of the Prephase (or at the first sign of progressive disease), all patients will proceed to cycle 1 of O-ICE. O-ICE chemotherapy is given in 21-day (3-week) cycles. Three weekly doses of obinutuzumab will be given days -2 (during the prephase), +6 and +13. Patients will receive ICE chemotherapy (ifosfamide-carboplatin-etoposide) administered on Days 0-2 of Cycle 1.
Drug: Obinutuzumab
Drug will be given alone in a pre-phase and in combination with ICE chemotherapy.
Other Names:
  • Gazyva
Drug: Liposomal ARA-C
Will be given intrathecally for both prophylaxis and treatment of CNS disease.
Other Names:
  • Depocyte
Drug: Ifosfamide
Ifosfamide 3000 mg/m2/day as a 2 hour IV infusion daily x 3 days (Days 0,1,2) of Cycle 1 and 2.
Other Names:
  • Ifex
Drug: Carboplatin
Carboplatin: 635 mg/m2 as 1 hour IV infusion on Day 0 only of Cycle 1 and 2.
Other Names:
  • Paraplatin
Drug: Etoposide
Etoposide: 100 mg/m2/day as 1 hour IV infusion daily x 3 days (Days 0,1,2).
Other Names:
  • VP-16
Experimental: CNS Positive
All patients will receive 4 doses of obinutuzumab on days -14, -10, -6 and -2. Patients with positive CSF prior to enrollment will receive treatment with two doses of Liposomal cytarabine during the prephase portion of therapy. Liposomal cytarabine will be given intrathecally on days -13 and -5. Dexamethasone will be given for 5 days with each Liposomal cytarabine dose starting the day prior to the Liposomal cytarabine. Dexamethasone will be given days -14 to -10 and days -6 through -2. Following completion of the Prephase (or at the first sign of progressive disease), all patients will proceed to cycle 1 of O-ICE. O-ICE chemotherapy is given in 21-day (3-week) cycles. Three weekly doses of obinutuzumab will be given days -2 (during the prephase), +6 and +13. Patients will receive ICE chemotherapy (ifosfamide-carboplatin-etoposide) administered on Days 0-2 of Cycle 1.
