Clinical Trial Summary

This study will evaluate the safety, tolerability, and pharmacokinetics of RO7617991, and will make a preliminary assessment of the anti-tumor activity of RO7617991 in human leukocyte antigen (HLA)-A*02 eligible patients with locally advanced or metastatic melanoma-associated antigen A4 (MAGE-A4)-positive solid tumors.

Intervention

Drug:
• RO7617991
RO7617991 will be administered by intravenous (IV) infusion. Treatment will continue until unacceptable toxicity or loss of clinical benefit as determined by the investigator.
• Tocilizumab
Tocilizumab 8 mg/kg IV will be administered to patients when necessary to treat potential cytokine release syndrome (CRS), as described in the protocol.
