Study BP29541 is a first-in-human, open-label, multi-center, dose-escalation Phase I clinical study of single-agent RO6958688 in participants with locally advanced and/or metastatic carcinoembryonic antigen (CEA) positive solid tumors who have progressed on standard treatment, are intolerant to standard of care (SOC), and/or are non-amenable to SOC. The study will be conducted in two parts. Part I of the study will investigate the safety and pharmacokinetics of a single dose of RO6958688 in single participant cohorts with dosing starting from a minimal anticipated biological effect level dose of 0.05 milligrams (mg) and up to a maximum dose of 2.5 mg. Part II will establish the appropriate therapeutic dose based on safety, pharmacokinetics, and the maximum tolerated dose (MTD) of RO6958688 for the once per week (QW) regimen, every three weeks (Q3W) regimen, and for the step up dosing regimen.
