Double attack on mutant KRAS: can two targeted drugs outsmart resistant cancers?
NCT ID NCT05288205
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This early-phase trial is testing whether combining two experimental drugs, JAB-21822 and JAB-3312, can safely shrink or control advanced solid tumors that carry a specific KRAS G12C mutation. The study includes people with cancers like non-small cell lung, colorectal, or pancreatic cancer who have run out of standard options. The goal is to find the best dose and see how well the combination works against these hard-to-treat tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A combination of two experimental targeted drugs: JAB-21822 (a KRAS G12C inhibitor) and JAB-3312 (an SHP2 inhibitor)
- What this could lead to
- If this combination works, it could offer a new treatment option for people with advanced cancers that carry a specific KRAS mutation, potentially shrinking tumors and slowing disease progression.
- What could go wrong
- This is an early-phase trial, so the safety and effectiveness are not yet proven. The combination may cause side effects or may not work for everyone. Success in this small study does not guarantee broader benefit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
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 metastasis for \> 3 years after treatment, without current evidence of tumor, and without significant risk of recurrence of previous malignant diseases in the opinion of the study doctor may also be enrolled; * Serious allergy to the investigational drug or excipients (such as microcrystalline cellulose, etc.); * Patients with previous (≤ 6 months before the initiation of treatment) or current severe autoimmune diseases (including adverse reactions caused by previous anti- tumor immunotherapies), or autoimmune diseases requiring long-term systemic hormone therapy at immunosuppressive dose levels (prednisone \> 10 mg/day or equivalent drugs); * HIV, hepatitis B virus(HBV), or hepatitis C virus(HCV) positive; * Previous (≤ 6 months prior to the first dose) or current evidence of the following diseases: acute myocardial infarction, unstable angina and cerebrovascular accident; * Subjects who have impaired cardiac functions or clinically significant cardiac diseases; * Pregnant or lactating women
