NCT ID NCT05120349

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This phase 3 trial tests whether the targeted drug osimertinib (Tagrisso) can prevent lung cancer from returning in patients with early-stage (IA2-IA3) non-small cell lung cancer that has a specific EGFR mutation. About 390 participants who have had complete tumor removal surgery will receive either osimertinib or a placebo daily. The study measures how long they remain cancer-free and overall survival, with treatment continuing until the cancer returns or side effects become unacceptable.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Osimertinib (Tagrisso), a targeted cancer pill
What this could lead to
If successful, this could offer a way to reduce the risk of early-stage lung cancer returning after surgery, potentially improving long-term survival.
What could go wrong
This is an early-stage cancer trial, and the benefit over placebo may be small. Side effects like rash, diarrhea, or lung inflammation are possible, and the drug must be taken indefinitely until recurrence or toxicity.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria 1. Male or female, at least ≥ 18 years. 2. NSCLC, of non-squamous histology. 3. Stage IA2 or IA3 disease, based on TNM8 classification. 4. Complete surgical resection (R0) of the primary NSCLC by lobectomy, bilobectomy, segmentectomy or sleeve resection. 5. Complete recovery from surgery at the time of randomisation. Study intervention cannot commence within 4 weeks following surgery. No more than 12 weeks may have elapsed between surgery and randomisation for participants. 6. World Health Organization performance status of 0 or 1. 7. Provision of tumour sample for central pathology assessment of pathologic risk factors and to assess EGFR mutation status prior to randomisation. 8. A tumour which harbours one of the 2 EGFR mutations (Ex19del, L858R) by cobas® EGFR Mutation Test v2 (Roche Diagnostics) or FoundationOne® test. 9. Minimum life expectancy of \> 6 months. 10. Females must be using highly effective contraceptive measures, and must have a negative pregnancy test prior to start of dosing if of child-bearing potential, or must have evidence of non-child-bearing potential. Male subjects must be willing to use barrier contraception. Exclusion Criteria 1. Mixed small cell and non-small cell cancer history. 2. Participants with incomplete (R1/R2) resection, or who have undergone pneumonectomy or only wedge resection. 3. Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses; or active infection including HCV and HIV or active uncontrolled HBV infection. 4. History of another primary malignancy, including any known or suspected synchronous primary lung cancer except for malignancy treated with curative intent with no known active disease ≥ 5 years before the first dose of study intervention and of low potential risk for recurrence. 5. Any of the following cardiac criteria: * Mean resting QTcF interval \> 470 ms, obtained from triplicate ECGs performed at screening. * Any abnormalities in rhythm, conduction, or morphology of resting ECG, * Any factors that increase the risk of QTcF prolongation or risk of arrhythmic events. 6. History of interstitial lung disease. 7. Inadequate bone marrow reserve or organ function. 8. Any unresolved toxicities from prior therapy greater than CTCAE Grade 1 at the time of starting study intervention. 9. Prior treatment with any anticancer therapy for NSCLC (including chemotherapy, radiotherapy, immunotherapy, and EGFR-TKIs). 10. Major surgery or significant traumatic injury within 4 weeks of the first dose of study intervention. 11. Participants currently receiving medications or herbal supplements known to be strong inducers of CYP3A4.
