About this study

Official title: A Phase II, Open-Label, Single-Arm Study of JS212 in Combination With JS111 as First-Line Treatment in Patients With Epidermal Growth Factor Receptor (EGFR)-Mutant Advanced Non-Small Cell Lung Cancer (NSCLC)

This is a single-arm clinical study evaluating the safety, tolerability, and preliminary efficacy of JS212 in combination with JS111 as first-line treatment in participants with epidermal growth factor receptor (EGFR)-mutant locally advanced or metastatic non-small cell lung cancer (NSCLC) who have not received prior systemic therapy for advanced disease.

The study consists of a safety lead-in stage followed by a clinical expansion stage. Approximately 20 participants are planned to be enrolled across the two stages. Participants will receive JS212 by intravenous infusion on Day 1 of each 21-day cycle and JS111 at 160 mg orally once daily until treatment discontinuation criteria are met.

During the safety lead-in stage, up to 10 participants will be enrolled and monitored for significant toxicities during the first 21 days after initial administration. The Safety Monitoring Committee (SMC) will review available safety, tolerability, and efficacy data and determine the JS212 dose to be further evaluated, whether an additional higher or lower dose should be explored, and whether the study may proceed to the clinical expansion stage.

Read the detailed description

This is a single-arm clinical study designed to evaluate the safety, tolerability, and preliminary antitumor activity of JS212 in combination with JS111 as first-line treatment in participants with EGFR-mutant locally advanced or metastatic NSCLC who have not previously received systemic therapy for EGFR-mutant advanced disease.

Participants will receive JS212 by intravenous infusion on Day 1 once every 3 weeks (Q3W), in combination with JS111 at 160 mg administered orally once daily (QD). Each treatment cycle is 21 days. Study treatment will continue until disease progression, unacceptable toxicity, withdrawal of consent, or another protocol-defined treatment discontinuation criterion is met.

The study includes two sequential stages: a safety lead-in stage and a clinical expansion stage. Approximately 20 participants are planned to be enrolled in total, although the final sample size may be adjusted by the Safety Monitoring Committee based on accumulating safety, tolerability, and efficacy data.

Safety Lead-in Stage

Up to 10 participants will be enrolled in the safety lead-in stage. The first 21 days following the initial administration of JS212 and JS111 will constitute the significant toxicity observation period.

The SMC will review the accumulated data and determine the JS212 dose to be used in combination with JS111 during the clinical expansion stage.

Before study initiation or during study conduct, the SMC may also consider emerging safety, tolerability, pharmacologic, and efficacy data from other ongoing studies of JS212 administered as monotherapy or in combination with other agents. Based on these data, the SMC may recommend modification of the JS212 dose, evaluation of another dose level, or omission of the safety lead-in stage and direct initiation of the clinical expansion stage, as specified in the SMC Charter.

Clinical Expansion Stage

After review of the safety lead-in data, participants enrolled in the clinical expansion stage will receive the SMC-selected dose of JS212 in combination with JS111 at 160 mg QD. The clinical expansion stage will further characterize the safety, tolerability, and preliminary antitumor activity of the combination.

Treatment will be administered in 21-day cycles and will continue until disease progression, unacceptable toxicity, withdrawal of consent, or another protocol-defined treatment discontinuation criterion is met. The study is expected to enroll approximately 20 participants in total across the safety lead-in and clinical expansion stages. The SMC may adjust the number of participants based on emerging study data.

Study Objectives

The primary objective is to evaluate the safety and tolerability of JS212 in combination with JS111 and to determine the JS212 dose to be further evaluated in combination with JS111.

The secondary or exploratory objective is to evaluate the preliminary antitumor activity of JS212 in combination with JS111 as first-line treatment in participants with EGFR-mutant locally advanced or metastatic NSCLC.

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 11 inclusion and 29 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: opening soon, as of the sponsor's last update on 20 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.

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 (+8618168028925, kui_zhang@junshipharma.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?
