Brief Summary:
This Phase Ib, open-label, dose-escalation study will evaluate the safety, tolerability, and pharmacokinetics of the combination of MOXR0916 and atezolizumab in participants with locally advanced, recurrent, or metastatic incurable solid malignancy that has progressed after available standard therapy; or for which standard therapy has proven to be ineffective or intolerable or is considered inappropriate; or for which a clinical trial of an investigational agent is a recognized standard of care. Participants will be enrolled in two stages: a dose-escalation stage and an expansion stage.

Condition or disease Intervention/treatment Phase
Neoplasms Drug: Atezolizumab (MPDL3280A), an engineered anti-programmed death-ligand 1 [PD-L1] antibody Drug: MOXR0916, a humanized agonist anti-OX40 monoclonal antibody Phase 1

Arms and Interventions

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Dose Escalation: MOXR0916 + Atezolizumab
Cohorts of at least 3 participants each will be treated at escalating doses of MOXR0916 in combination with a fixed dose of atezolizumab to determine the MTD or maximum administered dose (MAD).
 Drug: Atezolizumab (MPDL3280A), an engineered anti-programmed death-ligand 1 [PD-L1] antibody
Atezolizumab will be administered intravenously.
Other Name: Tecentriq

Drug: MOXR0916, a humanized agonist anti-OX40 monoclonal antibody
MOXR0916 will be administered intravenously.
Experimental: Expansion: MOXR0916 + Atezolizumab
Approximately 250-580 participants will be enrolled in the expansion stage to better characterize the safety, tolerability, pharmacokinetic variability, biomarkers of anti-tumor activity, and preliminary efficacy of MOXR0916 + atezolizumab in different cancer types.
 Drug: Atezolizumab (MPDL3280A), an engineered anti-programmed death-ligand 1 [PD-L1] antibody
Atezolizumab will be administered intravenously.
Other Name: Tecentriq

Drug: MOXR0916, a humanized agonist anti-OX40 monoclonal antibody
MOXR0916 will be administered intravenously.
