About this study
Official title: A Phase I Dose Escalation and Expansion Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Clinical Activity of RO7673396 as a Single Agent and in Combination With Other Anticancer Therapies in Patients With Advanced Solid Tumors Harboring RAS Mutation(s)
This study aims to evaluate the safety and tolerability of RO7673396 in participants with advanced solid tumors harboring RAS mutation(s). This study consists of two stages: Stage 1 (Dose Escalation) and Stage 2 (Dose Expansion). Stage 1 will define the recommended dose(s) for expansion (RDEs) of RO7673396. Stage 2 will evaluate preliminary anti-tumor activity of the RDE(s) defined in Stage 1 and of other doses of interest for future development in selected solid tumor indications.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing RO7673396 in people with Neoplasms, run by Hoffmann-La Roche at 25 sites in 11 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 25 sites in United States, China, Spain, Australia, New Zealand and 6 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Reference Study ID Number: YO45758 https://forpatients.roche.com/ (888-662-6728 (U.S.), global-roche-genentech-trials@gene.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Stage I: Number of Participants With Adverse Events (AEs) (time frame: Up to approximately 40 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2026.
