Study Details

Study Description

Brief Summary

This is a prospective, multi-center clinical study to enroll 59 patients with relapsed and refractory MZL. The study was designed to assess the efficacy and safety of the combination of obintuzumab and lenalidomide in the treatment of relapsed and refractory(R/R) marginal zone lymphoma (MZL).

Condition or Disease Intervention/Treatment Phase
  • Drug: Obinutuzumab, lenalidomide
Phase 2

Detailed Description

Marginal zone lymphoma(MZL) is incurable, the vast majority of MZL patients eventually will face disease relapsing or progression .

There is no standard second-line treatment for relapsed/refractory MZL, and the synergistic effect of obintuzumab and lenalidomide had been verified in other indolent lymphomas.

This trial is designed to investigate the efficacy and safety of the combination of obintuimab(GA101) and lenalidomide(GL therapy) in R/R marginal zone lymphoma, in order to find a safe and effective option in this type of disease.

Arms and Interventions

Arm Intervention/Treatment
Experimental: LG(Obintuzumab and lenalidomide ) Arm

Obintuzumab(GA101), lenalidomide Patients were treated with obintuzumab and lenalidomide for 6 cycles as induction, then followed by 2-year- maintenance

Drug: Obinutuzumab, lenalidomide
The treatment is divided into two phases: induction therapy and maintenance therapy Induction: 6 cycles, every 28 days/cycle Lenalidomide: 20 mg/day, oral. Dosing on Days 2-22 of Cycles 1-6 Obinutuzumab pegol: 1000 mg each time, administered on Days 1, 8, and 15 of Cycle 1, and on Day 1 of Cycles 2-6. ( 8 total infusions) Maintenance: Patients who achieved at least a partial response after 6 months of induction therapy were eligible to enter the maintenance phase for 2 years During the first year of maintenance therapy, patients received obinutuzumab (1000 mg on Day 1 of each 28-day cycle, every 2 cycles for 6 infusions) and lenalidomide (10 mg on Days 2-22 of each 28-day cycle, 12 cycles) until disease progression or end of treatment During the second year of maintenance therapy, patients received rituximab (6 infusions of 1000 mg) every 2 cycles (28 days each) until disease progression or end of treatment

  • Outcome Measures

    Primary Outcome Measures

    1. Overall Remission Rate(ORR) [24 weeks]

      Disease response evaluation after 6 cycles will be used to determine the overall remission rate

    Secondary Outcome Measures

    1. 2-year Progression Free Survival (PFS24): [up to 4.5 years]

      Progression-Free Survival will be measured according to the Cheson 2007 criteria. Responding patients and patients who are lost to follow up will be censored at their last tumor assessment date.

    2. 2-year Event-Free Survival (EFS24) [up to 4.5 years]

      Event-Free Survival will be measured from the date of inclusion to the date of first documented disease progression, relapse, initiation of new anti-lymphoma therapy or death from any cause.

    3. Complete Response Rate (CR) [24 weeks]

      Disease response evaluation after 6 cycles will be used to determine the overall remission rate

    4. Overall survival (OS) [up to 4.5 years]

      Overall survival will be measured from the date of inclusion to the date of death from any cause. Alive patients will be censored at their last date known to be alive

    Eligibility Criteria


    Ages Eligible for Study:
    18 Years and Older
    Sexes Eligible for Study:
