JS212 Plus JS111 in EGFR-Mutant Advanced NSCLC: A Phase II Study
China35 participantsStarted 2026-04-21
Plain-language summary
This is a Phase II study evaluating the safety, tolerability, pharmacokinetics, and preliminary efficacy of JS212 in combination with JS111 in patients with advanced or metastatic non-small cell lung cancer (NSCLC) harboring EGFR-sensitizing mutations who have progressed after prior EGFR-TKI therapy.
The study consists of two parts: a dose-escalation phase followed by an expansion phase. Approximately 30 participants will be enrolled. The dose-escalation phase will explore the safety and tolerability of escalating doses of JS212 in combination with a fixed dose of JS111, using a Bayesian optimal interval (BOIN) design. Based on safety and tolerability data, a recommended Phase III dose (RP3D) will be determined. The expansion phase will further evaluate safety and preliminary anti-tumor activity at the selected dose level.

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.
1This trial combines two drugs — JS212 and JS111 — which I haven't heard of before; can you explain what each one does and why pairing them together might matter for EGFR-mutant lung cancer specifically?
2Since this is a Phase II trial, there's still a lot being figured out about safety and how well this combination works — does that level of uncertainty feel appropriate for where I am in my treatment journey, or would starting with a more established EGFR-targeted therapy make more sense for me first?
3One of the main things this study is measuring is something called RP3D, which I understand is about finding the right dose to use going forward — what does it mean for me as a patient if the optimal dose hasn't been fully established yet?
4The trial is also closely tracking adverse events as a primary outcome, which suggests safety is still being actively characterized — what side effects are you most concerned about with this combination given my overall health and current condition?
5Am I the kind of patient this trial is designed for — do my specific EGFR mutation type and treatment history actually match what they're looking for, or are there other trials or approved options that might be a stronger fit right now?

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.
