Inclusion criteria
. Men or women ≥ 18 years old
. Eastern Collaboration Oncology Group (ECOG) performance status (PS) scored of 0-1.
. Estimated life expectancy \>12 weeks.
. Patients must have at least one assessable lesion in the dose-escalation part and one measurable lesion in the dose-expansion part per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
. In the dose-escalation part, patients must have histologically or cytologically confirmed advanced solid tumors harboring the KRAS p.G12C mutation and have progressed after standard therapy, or standard therapy is inappropriate or unavailable.
. Adequate organ function as defined in the below:
. Female patients with reproductive potential must have a negative serum pregnancy test within 7 days prior to the first dose. Both male and female patients of reproductive potential must be willing to abstain completely or agree to use an appropriate method of contraception during the entire study duration and for at least 3 months after the last dose of study medication.
. Willingness and ability to give informed consent and follow protocol procedures, and comply with follow-up visit requirements.
Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Incidence of Dose-limiting toxicities (DLTs)
Timeframe: 31 days after the first dose (single dose for 3 days and dose-escalation cycle 1 for 28 days)
. Dose-escalation phase: patients with known driver alterations other than KRAS p.G12C, e.g., EGFR, ALK, ROS1, RET, TRK, etc. (Enrollment of patients with co-mutations may be discussed with the investigator).
. Dose-expansion phase: prior use of selective KRAS inhibitors.
. Patients who received chemotherapy, radiotherapy, biological therapy, endocrine therapy, immunotherapy, and other anti-tumor treatment within 3 weeks before the first administration, except for the following: Nitrosourea or mitomycin C was received within 6 weeks before the first administration; Oral fluoropyrimidines and small molecule targeted drugs within 2 weeks or 5 half-lives of the drug (whichever is longer) prior to the first administration; Chinese proprietary medicines with anti-tumor indications were received within 2 weeks before the first administration.
. Received other unapproved investigational drugs or treatments within 4 weeks prior to the first administration.
. Have undergone major organ surgery (excluding needle biopsy) or had significant trauma within 4 weeks prior to the first administration.
. Unresolved toxicities from prior anti-tumor therapy, defined as not having resolved to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 grade ≤ 1(exceptions for toxicities judged by the investigator to be of no safety concern, e.g. alopecia, grade 2 peripheral neurotoxicity, etc.).
. Presence of spinal cord compression, meningeal metastases, clinically symptomatic brain metastases, or need for increased steroid doses to control central nervous system (CNS) disease; patients with symptomatic CNS metastases that are already under control may be eligible for this study.
. Patients with active infection who need systematic anti-infective therapy within 2 weeks prior to the first administration.
