Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Glofitamab
Treatment: Drugs - Obinutuzumab
Treatment: Drugs - Tocilizumab

Experimental: Part I: Dose Escalation - Participants (single participant cohorts) will receive obinutuzumab (Gpt) 1000 milligrams (mg) single dose IV infusion on Day -7 (pre-treatment) 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 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 obinituzumab (Gpt) 1000 milligrams (mg) IV infusion on Day -7 (pre-treatment); 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 every 2 or 3 week 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 every 3 week cycle until either the MTD/OBD is defined.
Step-up dosing: Q3W, participants will receive an initial low dose of glofitamab on C1D1, followed by a higher dose on C1D8; the total dose in C1 will not exceed the previously determined MTD. Higher doses may be explored from C2 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 (pre-treatment), 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.


Treatment: Drugs: Glofitamab
Glofitamab will be administered at a dose and as per the schedule specified in the respective arms.

Treatment: Drugs: Obinutuzumab
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.

Treatment: Drugs: Tocilizumab
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.

Summary
Brief summary
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-to-human 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.
