A Study to Assess the Safety and Pharmacokinetics of MOXR0916 and Atezolizumab (Also Known as MPDL3280A or Anti-PD-L1) in Participants With Locally Advanced or Metastatic Solid Tumors

Phase 1
Completed
Conditions
Neoplasms
Interventions
Drug: MOXR0916, a humanized agonist anti-OX40 monoclonal antibody
Registration Number
NCT02410512
Lead Sponsor
Genentech, Inc.
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.

Dose Escalation: MOXR0916 + AtezolizumabAtezolizumab (MPDL3280A), an engineered anti-programmed death-ligand 1 [PD-L1] antibodyCohorts 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).
Expansion: MOXR0916 + AtezolizumabAtezolizumab (MPDL3280A), an engineered anti-programmed death-ligand 1 [PD-L1] antibodyApproximately 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.
Expansion: MOXR0916 + AtezolizumabMOXR0916, a humanized agonist anti-OX40 monoclonal antibodyApproximately 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.
