Clinical Trials

CO40939 is a Phase Ib, open-label, multicenter, single-arm study designed to evaluate the safety, efficacy, pharmacokinetics, and immunogenicity of cibisatamab in combination with atezolizumab administered after pretreatment with obinutuzumab in patients with Stage IV microsatellite stable (MSS) metastatic colorectal cancer (mCRC) whose tumors have high carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5) expression and who have progressed on two or more chemotherapy regimens. The study is composed of a safety run-in and an exploratory part.

The dose-escalation of RO7122290 will use a QW dosing schedule of RO7122290 in combination with a Q3W dosing interval for cibisatamab with obinutuzumab pre-treatment. The starting dose for RO7122290 will be 35 mg, which represents the human equivalent dose for the minimal pharmacologically active dose (1 mg/kg) in mice.

Part II of this study will evaluate selected dose levels of RO7122290 from Part I (a QW RO712290 administration in combination with a Q3W cibisatamab administration with obinutuzumab pre-treatment) in a Q3W regimen in combination with a Q3W cibisatamab administration with obinutuzumab pre-treatment.

RO7122290 will be administered using a QW (Part I) or Q3W (Part I or Part II) schedule in combination with 100 mg cibisatamab Q3W with obinutuzumab pre-treatment. The maximum dose of RO7122290 to be explored in combination with cibisatamab with obinutuzumab pre-treatment in this study is 500 mg for the QW dosing interval (Part I) or 1500 mg for the Q3W dosing interval (Part I or Part II).

RO7122290

Cibisatamab will be administered to participants at a fixed dose of 100 mg Q3W (100 mg on Day 1 of each 21-day cycle).

Obinutuzumab will be administered (IV) as pre-treatment on Day - 8/- 7 (split dose) or

- 8 (single dose) prior to C1D1 of cibisatamab and as re-treatment every 6 months if the participant is still receiving cibisatamab

This is an open-label, multicenter, Phase Ib study to determine the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) in the weekly (QW) and/or every 3 weeks (Q3W) regimens, safety, tolerability, PK, immunogenicity, PD profile and to evaluate preliminary anti-tumor activity of RO7122290 in combination with cibisatamab Q3W after pretreatment with obinutuzumab, in participants with previously treated metastatic, microsatellite-stable colorectal adenocarcinoma with high CEACAM5 expression

The DLT observation period is defined as a period of 21 days after the first administration of RO7122290 combined with cibisatamab. Additional days (maximum 3 days per dosing) are allowed in case of treatment delays for non-safety reasons.

Participants are evaluable for DLT assessment, if they have received one dose of cibisatamab and at least two doses of RO7122290 during the DLT period.

Objective response rate (ORR) is determined as the rate of participants with an objective tumor response of CR or PR. ORR will be derived for RECIST Version 1.1 and will be based on Investigators' assessment.

Disease control rate (DCR) is determined as the rate of participants with an objective tumor response of CR, PR or SD. DCR will be derived for RECIST Version 1.1 and will be based on Investigators' assessment.

DoR will be calculated for participants who have a best overall response of CR or PR and will be defined as the time from first occurrence of a documented OR until the time of documented disease progression or death (death within 30 days from last study treatment) from any cause, whichever occurs first. Censoring

PFS will be defined as the time from first dose of cibisatamab or RO7122290 (C1D1) to the first occurrence of documented disease progression (based on RECIST Version 1.1 Investigator's assessment) or death from any cause, whichever occurs first. For participants who do not have documented progressive disease or death (within 30 days from last study treatment) during the study, PFS will be censored at the day of the last tumor assessment. Participants without any post-baseline assessments or with all post-baseline assessments having unknown result/response but known to be alive at the clinical cut off for the analysis will be censored at the date of study treatment initiation plus one day.
