About this study
Official title: A Phase II Study of JS212 in Combination With JS111 in Patients With Epidermal Growth Factor Receptor (EGFR)-Mutant Advanced Non-Small Cell Lung Cancer (NSCLC)
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.
Read the detailed description
This is an open-label, multicenter Phase II study designed to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of JS212 in combination with JS111 in patients with EGFR-mutant advanced or metastatic NSCLC who have experienced disease progression following prior EGFR-TKI therapy.
The study includes two sequential parts: a dose-escalation phase and a dose-expansion phase, with an overall planned enrollment of approximately 30 participants.
Dose-Escalation Phase Up to approximately 15 participants will be enrolled in the dose-escalation phase. JS212 will be administered intravenously once every 3 weeks (Q3W) at predefined dose levels, starting at 4.2 mg/kg, with potential escalation to 4.6 mg/kg or other dose levels as determined by the Safety Monitoring Committee (SMC). JS111 will be administered orally at a fixed dose of 160 mg once daily (QD).
A Bayesian optimal interval (BOIN) design will be used to guide dose escalation. Participants will be enrolled in cohorts of at least 3 subjects. Dose-escalation decisions will be based on the occurrence of dose-limiting toxicities (DLTs) observed within the first 21 days following the initial dose. The SMC will review safety data and make decisions regarding dose escalation, dose de-escalation, dose expansion, or study modification.
Dose escalation will continue until one of the following conditions is met:
The maximum planned sample size for dose escalation is reached (approximately 15 participants or as adjusted by the SMC); A dose level reaches sufficient evaluable participants with acceptable safety profile; Dose elimination criteria are met due to excessive toxicity; Early termination is determined by the sponsor and investigators. The SMC may also adjust dose levels, dosing schedules, or study design based on emerging safety data from this or other ongoing studies of JS212.
Dose-Expansion Phase Following completion of the dose-escalation phase, one dose level of JS212 in combination with JS111 will be selected for further evaluation. Approximately 20 participants are planned to be enrolled in the expansion phase (subject to adjustment).
Participants will receive JS212 in combination with JS111 every 21 days per cycle until disease progression, unacceptable toxicity, withdrawal of consent, or other discontinuation criteria are met.
Dose-Limiting Toxicity (DLT)
DLTs are defined as treatment-related adverse events occurring within 21 days after the first dose, graded according to NCI-CTCAE v6.0. These include:
Hematologic toxicities, such as:
Grade 4 thrombocytopenia or Grade 3 thrombocytopenia with bleeding; Febrile neutropenia ≥ Grade 3; Grade 4 neutropenia lasting >7 days; Grade 4 anemia;
Non-hematologic toxicities ≥ Grade 3, excluding:
Transient (≤5 days) manageable Grade 3 gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea); Transient (≤7 days) liver enzyme elevations not meeting Hy's law; Asymptomatic laboratory abnormalities; Correctable electrolyte abnormalities within 3 days; Skin toxicities or infusion-related reactions;
Additional toxicities may be considered DLTs at the discretion of the SMC, including persistent or recurrent treatment-related adverse events leading to significant treatment delay or discontinuation.
Study Objectives The primary objectives are to evaluate the safety and tolerability of JS212 in combination with JS111 and to determine the recommended Phase III dose (RP3D). Secondary objectives include assessment of pharmacokinetics and preliminary anti-tumor activity.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing JS212 for Injection＋JS111 capsules (AP-L1898) in people with Locally Advanced, Metastatic, or Recurrent Non-small Cell Lung Cancer (NSCLC) Harboring Epidermal Growth Factor Receptor (EGFR) Mutations, run by Shanghai Junshi Bioscience Co., Ltd. at 2 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 22 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 7 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Kui Zhang, Project Directer (08618168028925, kui_zhang@junshipharma.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
ORR (time frame: up to 3 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2026.
