About this study

Official title: An Open-label, Multicenter Phase Ib/II Clinical Study to Evaluate the Safety, Efficacy, and Pharmacokinetic of PLB1004 Capsules Combined With Platinum-based Doublet Chemotherapy in Patients With EGFR Mutation-positive NSCLC

Tyrosine Kinase Inhibitor (TKI) that targets Epidermal Growth Factor Receptor (EGFR) mutations. Unfortunately, despite the benefit observed for patients treated with EGFR-TKI, the vast majority of cancers are expected to develop resistance to the drug over time. The exact reasons why resistance develops are not fully understood but based upon clinical research it is hoped that combining PLB1004 with another type of anti-cancer therapy known as chemotherapy will delay the onset of resistance and the worsening of a patient's cancer.

In recent years, clinical studies on the combination of EGFR-TKI and chemotherapy have made important progress, suggesting that the combination of EGFR-TKI and chemotherapy further enhances the therapeutic benefit in EGFR-mutant positive NSCLC.

Both preclinical and clinical data indicate that PLB1004 exhibit good antitumor activity and relatively durable efficacy in NSCLC patients with EGFR mutations. They can reduce tumor burden, control tumor progression, and improve the survival benefit of patients, which is expected to provide an effective treatment option for such patients.

Read the detailed description

This study is a multicenter, open-label, dose-escalation and dose-expansion Ib/II phase study, aiming to evaluate the clinical safety, tolerability, PK and preliminary efficacy of PLB1004 combined with platinum-based doublet chemotherapy in NSCLC patients with EGFR mutations. The study consists of two parts: the phase Ib dose-escalation study and dose-expansion study, as well as the phase II clinical study. The target population of the phase Ib study is patients with confirmed locally advanced or metastatic NSCLC harboring EGFR mutations who have received or not received systemic antitumor therapy. The II phase clinical study sets up two cohorts. Cohort 1: patients with confirmed locally advanced or metastatic NSCLC harboring EGFR mutations who have received or not received systemic antitumor therapy; Cohort 2: patients with newly diagnosed resectable stage II-III NSCLC harboring EGFR mutations who have not received systemic antitumor therapy. A total of 79-108 patients are planned to be enrolled in the study, which is divided into a screening period, a treatment period and a follow-up period. During the administration of the study drug, follow-up will be conducted every 6 weeks in the first year and every 12 weeks from the second year onwards.

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 16 inclusion and 14 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 28 Oct 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 Shun Lu M.D, Ph.D. (86-21-22200000, shunlu@sjtu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase Ib: Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]) (time frame: 12 months). The study lists 6 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 28 Oct 2026.
