An Open-Label, Single-Arm, Dose-Escalation Phase I Study Evaluating the Safety, Tolerability, and Preliminary Efficacy of EDB-102 in Patients With EGFR L858R-Mutant, Third-Generation TKI-Resistant Advanced Non-Small Cell Lung Cancer With Liver Metastases
15 participantsStarted 2026-02-10
Plain-language summary
The purpose of this study is to evaluate the safety, tolerability, and preliminary efficacy of EDB-102 Injection in patients with advanced non-small cell lung cancer (NSCLC) who have liver metastases. The study specifically targets patients harboring the EGFR-L858R mutation who have disease progression after treatment with third-generation EGFR tyrosine kinase inhibitors (TKIs, e.g., osimertinib).
EDB-102 is a novel in vivo gene-editing therapy. It consists of CRISPR-Cas9 mRNA and a single-guide RNA (sgRNA) encapsulated in lipid nanoparticles (LNPs). The drug is designed to specifically identify and disrupt the mutant EGFR-L858R gene in tumor cells, thereby inhibiting tumor growth. Due to the liver-targeting properties of the LNP carrier, this therapy is particularly aimed at patients with liver metastases.
This is a Phase I, open-label, dose-escalation study. Participants will receive a single intravenous (IV) infusion of EDB-102. The study will follow a "3+3" design to determine the maximum tolerated dose (MTD) and the recommended Phase II dose (RP2D). Participants will be monitored for adverse events, and tumor biopsies will be collected to assess the gene-editing efficiency of the drug.

Inclusion criteria
. Age ≥18 and ≤75 years, any sex.
. Histologically or cytologically confirmed, unresectable locally advanced or metastatic (stage IV) non-small cell lung cancer (NSCLC)
. Prior treatment with at least one third-generation EGFR-TKI (e.g., osimertinib) with radiologically confirmed disease progression according to RECIST 1.1 or intolerance, and no concomitant anticancer therapy during this period.
. Availability of tumor tissue obtained after progression on third-generation EGFR-TKI, with EGFR L858R mutation confirmed in the post-progression tumor tissue or blood sample by central laboratory- or study site-validated methods (e.g., WES or RNAseq).
. At least one measurable hepatic lesion per RECIST 1.1, confirmed by biopsy, with the EGFR L858R mutation verified in the lesion by central laboratory- or study site-validated methods (e.g., WES or RNAseq).
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.
