Recruiting nowPhase 2
What this trial is trying to do
The researchers are testing JAB-21822, which directly inhibits the KRAS G12C cancer-driving protein, together with JAB-3312, an SHP2 inhibitor intended to block signalling that can help cancer cells escape KRAS inhibition. They will increase the doses and then expand treatment at the recommended phase-2 dose in people whose advanced solid tumours carry KRAS G12C.
The idea is that blocking KRAS G12C and a related escape pathway together could control the cancer better than blocking KRAS G12C alone. This trial is mainly measuring safety, tolerability, drug levels and the dose to take forward; it has no comparison group and is not designed to show longer survival.
Worth knowing: This is an early-phase, open-label, non-randomised trial, so any tumour responses seen cannot be separated from the effects of treatment without a comparison group.
Written from the trial's own registry entry to explain what the researchers are testing and why. Nothing here is a result — this trial has not reported one — and it is not a view on whether the treatment works or on whether it would suit you.

What is being tested
- Drug JAB-21822
- Drug JAB-3312
What it is measuring
recommended phase-2 dose (RP2D).
This is the trial's main question — the one it is designed and sized to answer. Anything else it reports is a secondary finding, and secondary findings are far more likely to be chance.
Phase 2. Tests whether the treatment works well enough to be worth a larger trial. Usually too small to prove it changes survival.
How the researchers describe it
This is a multicenter, open-label phase 1/2a study consisting of two parts: dose escalation phase and dose expansion phase. The objective of the dose escalation phase is to evaluate the safety, tolerability and pharmacokinetics of JAB-21822 in combination with JAB-3312 in patients with advanced solid tumors harboring KRAS p.G12C mutation and to determine the RP2D for the combination therapy. In the dose expansion phase, preliminary efficacy and safety of the combination therapy at the RP2D will be further explored in patients with specific cancer harboring KRAS p.G12C mutation.

Who the trial is looking for
Inclusion Criteria
- A written informed consent should be signed by a subject or his/her legal representative before any study-related procedures are performed;
- Subjects with histologically or cytologically confirmed locally advanced or metastatic advanced solid tumors harboring KRAS p.G12C mutation who have failed or lack standard-of-care (SOC) or are unwilling to undergo or intolerant to SOC;
- Expected survival ≥ 3 months;
- Subjects must have at least one measurable lesion as defined by RECIST v1.1. If no measurable lesion untreated with radiation is selected as the target lesion, a lesion treated with radiation ≥ 4 weeks before the first dose and with progression confirmed by radiography may be selected as the target lesion;
- Eastern Cooperative Oncology Group(ECOG) performance status 0-1;
- The organ functions of subjects meet the criteria for the following laboratory parameters at screening;
- Subjects must be able to swallow oral medications without gastrointestinal abnormalities that significantly affect drug absorption
Exclusion Criteria
- Patients with previous (≤ 3 years) or current tumors of other pathological types, except for cured cervical carcinoma in situ, ductal carcinoma in situ of the breast, prostatic intraepithelial neoplasia, superficial non-invasive bladder cancer, stage I skin cancer (except melanoma); subjects without recurrence or metas…

Where it is running
Running at 27 sites. Listed in: China.
Individual hospitals, and whether each is currently open, are listed on the registry record. Sites open and close throughout a trial.
Worth asking your oncology team
Being listed here is not a recommendation, and no one page can tell you whether a trial is right for you. These are the questions it raises.
- Is this trial open at a hospital I could realistically travel to?
- Given my stage, my previous treatment and my tumour's molecular profile, would I be eligible?
- What would I be giving up by joining — is the comparison arm the treatment I would otherwise be having?
- What is already known about the safety of what is being tested?
