Interventions

  • Glofitamab — DRUG
    Glofitamab will be administered at a dose and as per the schedule specified in the respective arms.
  • Obinutuzumab — DRUG
    Obinutuzumab 1000 mg single dose IV infusion on Day -7; or 2000 mg single dose administered on Day -7, or split into two 1000 mg doses administered on Days -1 and -7, and per the schedule specified in the respective arms.
  • Tocilizumab — DRUG
    Tocilizumab will be administered as an IV infusion, if required, for the management of severe Cytokine Release Syndrome (CRS) occurring during or after any infusion of glofitamab, as per the methods described in the Summary of Product Characteristics (SmPC) or other similar local prescribing documents.

Study Details

This is a Phase I/II, multicenter, open-label, dose-escalation study designed to evaluate the efficacy, safety, tolerability and pharmacokinetics (PK) of a novel T-Cell bispecific (TCB), glofitamab, administered by intravenous (IV) infusion as a single agent and in combination with obinutuzumab, following pre-treatment with a one-time, fixed dose of obinutuzumab. This entry-into-human (EIH) study is divided in 3 parts: dose escalation (Parts I and II) and dose expansion (Part III). Single-participant dose-escalation cohorts will be used in Part I, followed by conversion to multiple participant dose-escalation cohorts (Part II), in order to define a tentative maximum tolerated dose (MTD) or optimal biological dose (OBD). The expansion cohorts (Part III) will be initiated when the tentative MTD/OBD is defined, to further evaluate the safety, PK and therapeutic activity of glofitamab.

Arms

  • Experimental: Part I: Dose Escalation
    Participants (single participant cohorts) will receive obinutuzumab pretreatment (Gpt) 1000 milligrams (mg) single dose IV infusion on Day -7 followed by glofitamab IV infusion on Day 1 and Day 8 of Cycle 1. From Cycle 2 onwards, ascending doses of glofitamab will be administered on Day 1 of every 2 week (Q2W) cycle up to Cycle 12 (24 weeks) or until unacceptable toxicity or disease progression. Glofitamab dosing will be initiated at 5 micrograms (mcg) (flat dose) followed by doses of 15 mcg, 45 mcg, 135 mcg, 405 mcg and 810 mcg.
  • Experimental: Part II: Dose Escalation
    In each treatment regimen, participants will receive Gpt 1000 mg IV infusion on Day -7; or 2000 mg either administered on Day -7, or split into two 1000 mg doses on Days -1 and -7. The first glofitamab IV infusion will be given on Day 1 of Cycle 1 and a total of 12 cycles will be administered. Monotherapy, glofitamab as a single agent: ascending doses of glofitamab administered on Day 1 of Q2W or every 3 week (Q3W) cycle until either the MTD/OBD is defined. Combination Therapy: From Cycle 2 onwards, a fixed dose of 1000 mg obinutuzumab will be administered via IV infusion in combination with ascending doses of glofitamab on Day 1 of Q3W cycle until either the MTD/OBD is defined. Step-up dosing: Q3W, participants will receive an initial low dose of glofitamab on Cycle 1 Day 1, followed by a higher dose on Cycle 1 Day 8; the total dose in Cycle 1 will not exceed the previously determined MTD. Higher doses may be explored from Cycle 2 or later cycles.
  • Experimental: Part III: Dose Expansion
    Part III will start once MTD/OBD is defined. Participants will receive Gpt 1000 mg single dose IV infusion on Day -7, followed by glofitamab at a fixed dose regimen or step-up dose regimen on a Q2W or Q3W dosing schedule as determined in Part II. A total of 12 cycles will be administered. Combination Therapy: From Cycle 2 onwards, a fixed dose of 1000 mg obinutuzumab will be administered via IV infusion in combination with glofitamab at the dosing regimen determined in Part II.
