Obinutuzumab and ICE Chemotherapy in Refractory/Recurrent CD20+ Mature NHL

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).

  • Primary mediastinal B-cell lymphoma (PMBL)
  • CD20+ B-lymphoblastic lymphoma
  • Follicular lymphoma, Grade III
  • Karnofsky ≥ 60% for patients > 16 years of age and
  • Lansky ≥ 60 for patients ≤ 16 years of age.

  • Patients may not have received prior therapy with obinutuzumab (GA101)
  • Radiation Therapy (XRT): Date of receiving prior XRT must be > 2 weeks for local palliative XRT (small port); > 6 months must have elapsed if prior craniospinal XRT or if > 50% radiation of pelvis; > 6 weeks must have elapsed if other substantial bone marrow radiation.
  • Steroids: Patients may have received prior steroid treatment, but not started greater than 7 days prior to initiation of protocol therapy.
  • Adequate organ function.

Exclusion Criteria:
