Brief Summary

This is an open-label, multi-center, Phase Ib clinical study of cergutuzumab amunaleukin, in combination with atezolizumab, to investigate the safety, pharmacokinetics, and therapeutic activity in participants with locally advanced and/or metastatic carcinoembryonic antigen (CEA)-positive solid tumors, whose disease has progressed on or who are intolerant to the standard of care therapy. Enrolled participants who continue treatment will be treated until loss of clinical benefit, unacceptable toxicities, or withdrawal of consent. The study will include 2 parts: a dose-escalation Part I and a dose expansion Part II. The anticipated treatment period is 24 months for both cergutuzumab amunaleukin and atezolizumab and may be modified if emerging data suggest a benefit.

Study Groups

Cergutuzumab+Atezolizumab (Part I)

Participants will receive escalated IV doses of cergutuzumab amunaleukin in combination with atezolizumab. This is a Part I dose escalation phase of the study. Cergutuzumab amunaleukin will be escalated from a starting dose of 6 milligrams (mg) and dosing schedules of every week (qw) and every 2 weeks (q2w) may be explored. Atezolizumab will be administered in fixed flat doses of either 840 mg q2w or 1200 mg every 3 weeks (q3w). Treatment will be continued until loss of clinical benefit, unacceptable toxicities, or withdrawal of consent for a maximum treatment period of 24 months for both cergutuzumab amunaleukin and atezolizumab and may be modified if emerging data suggest longer treatment period is needed.

Group Type: EXPERIMENTAL

Atezolizumab

Intervention Type: DRUG

Participants will receive atezolizumab IV infusion at doses of 800 mg q2w or 1200 mg q3w.

This is a Part II expansion phase of the study. Participants will receive cergutuzumab amunaleukin at maximum tolerated dose (MTD) (or recommended dose) identified during Part I in combination with atezolizumab. Treatment will be continued until loss of clinical benefit, unacceptable toxicities, or withdrawal of consent for a maximum treatment period of 24 months for both cergutuzumab amunaleukin and atezolizumab and may be modified if emerging data suggest longer treatment period is needed.
