Neoadjuvant Osimertinib Plus Chemotherapy for EGFR-mutant Stage III N2 Non-squamous Non-small Cell Lung Cancer

Neoadjuvant Osimertinib + Chemotherapy for EGFR-mutant Stage III NSCLC (NCT05011487) is a Phase 2 interventional studying Non-Small Cell Lung Cancer, sponsored by Sun Yat-sen University. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Non-Small Cell Lung Cancer and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 30 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: - Histologically or cytologically documented N2 positive non-squamous NSCLC with resectable (Stage IIIA or T3-4N2 IIIB) disease (according to Version 8 of the IASLC Cancer Staging Manual \[IASLC Staging Manual in Thoracic Oncology 2016\]). - Complete surgical resection of the primary NSCLC must be deemed achievable, as assessed by a MDT evaluation (which should include a thoracic surgeon, specialized in oncologic procedures). - Eastern Cooperative Oncology Group (ECOG) PS of 0 or 1 at enrolment, with no deterioration over the previous 2 weeks prior to baseline or day of first dosing - A tumour which harbours one of the 2 common EGFR mutations known to be associated with EGFR-TKI sensitivity (Ex19del, L858R), either alone or in combination with other EGFR mutations (ie, T790M, G719X, Exon20 insertions, S7681 and L861Q). Who Should NOT Join This Trial: - Past medical history of ILD, drug-induced ILD, radiation pneumonitis which required steroid treatment, or any evidence of clinically active ILD. - History of another primary malignancy, except for the following: Malignancy treated with curative intent and with no known active disease ≥2 years before the first dose of investigational product (IP) and of low potential risk for recurrence; Adequately treated non-melanoma skin cancer or lentigo malignancy without evidence of disease; Adequately treated carcinoma in situ without evidence of disease - Patients who have pre-operative radiotherapy treatment as part of their care plan - Mixed small cell and NSCLC histology - T4 tumours infiltrating the aorta, the oesophagus and/or the heart; and/or any bulky N2 disease deemed unresectable - Patients who are candidates to undergo only segmentectomies or wedge resections - Prior treatment with any systemic anti-cancer therapy for NSCLC including chemotherapy, biologic therapy, immunotherapy, or any investigational drug - Prior treatment with EGFR-TKI therapy ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Bring the printable summary of this trial — including the NCT ID (NCT05011487), the sponsor (Sun Yat-sen University), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?
