Study Details
Study Description
Brief Summary
This is a Phase I open-label, multicenter study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary activity of tiragolumab administered as a single agent or in combination with atezolizumab and/or daratumumab or rituximab in participants with relapsed or refractory (R/R) multiple myeloma (MM) or R/R non-Hodgkin lymphoma (NHL).

Phase 1 |
Detailed Description
In the Phase Ia part of the study, tiragolumab is administered as a single agent in participants with R/R MM or R/R NHL.
In the Phase Ib part of the study, tiragolumab is administered in combination with atezolizumab and/or daratumumab in participants with R/R MM or with rituximab in participants with R/R NHL.

Drug: Daratumumab/rHuPH20
Administered by SC injection 1800 mg/30,000 U rHuPH20 weekly for a total of 6 doses, then every 3 weeks for a total of 16 doses (first dose given at Week 7), then every 4 weeks from Week 55 onward until disease progression
