Clinical Trial Summary

This is a first-in human, open-label, Phase 1 dose-escalation study in order to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) for intravenous (IV) and/or subcutaneous (SC) dosing schemes of this combination treatment, and to evaluate the safety, tolerability, pharmacokinetics, and preliminary anti-tumor activity of this combination treatment in participants with relapsed/refractory B-cell non Hodgkin lymphoma (r/r NHL).

Intervention

Drug:
• RO7443904
RO7443904 will be administered by subcutaneous (SC) or IV infusion on Cycle (C) 1 Day (D) 10, C2D3, and C2D8. From C3 onward, RO7443904 will be given every 3 weeks (Q3W), for up to 12 cycles (C = 21 days).
• Glofitamab
Glofitamab will be administered through IV infusion starting with step-up dosing (2.5 mg/10 mg/30 mg) on C1D1, C1D8, and C2D1. Starting in Cycle 3, glofitamab will be given in 30 mg doses every three weeks (Q3W) with RO7443904, for up to 12 cycles (Cycle = 21 days).
• Obinutuzumab
Obinutuzumab will be administered once through IV infusion, at a 1 g dose in Cycle 1, on either Day -7, -4, or -3 (C1D-7, C1D-4, C1D-3).
• Tocilizumab
Tocilizumab will be administered as necessary to treat cytokine release syndrome (CRS).
