A Study to Evaluate the Benefit of Adding Durvalumab After Chemotherapy, Durvalumab and Surgery in Patients With Early-stage, Operable, Non-small Cell Lung Cancer. (ADOPT-lung)

May 12, 2026 updated by: ETOP IBCSG Partners Foundation

An International, Multicentre, Open-label Randomised Phase III Trial to Evaluate the Benefit of Adding Adjuvant Durvalumab After Neoadjuvant Chemotherapy Plus Durvalumab in Patients With Stage IIB-IIIB (N2) Resectable NSCLC

ADOPT-lung is an international, multicentre, open-label randomised phase III trial. Protocol treatment consists of 3-4 cycles of neoadjuvant durvalumab in combination with platinum-based doublet chemotherapy, followed by surgery. Patients with R0 and R1 only resection will be randomised to receive either adjuvant durvalumab for 12 cycles (experimental arm) or observation (control arm). The primary objective of the study is to determine whether additional adjuvant immunotherapy with durvalumab after neoadjuvant chemo-immunotherapy has an effect on disease-free survival (DFS) in patients who do not achieve complete pathological response (pCR) as per local assessment according to the IASLC recommendations.

  • Stage IIB-IIIB (T1-4 N0-2) according to 8th edition of the TNM staging system of lung cancer.

Stage III assessment should include samples of lymph nodes at levels 4, bilaterally, and level 7 to rule out stage IIIB N3 disease.

T4 tumours will only be eligible if they are defined as T4 based only on their size (>7cm); any other reason will be considered ineligible.

  • Known PD-L1 status, as tested locally using a validated assay. To ensure comparability of results, it is strongly encouraged that PD-L1 testing is done with the Ventana PD-L1 (SP263) assay.
  • Absence of EGFR mutation or ALK translocation, as tested locally.
  • Primary tumour resectable and functionally operable as assessed per local multidisciplinary tumour board (cardiac evaluation, pulmonary function and diffusion capacity, comorbidity).

  • Written IC for study participation must be signed and dated by the patient and the investigator prior to any study-related intervention.

Eligibility Criteria for randomisation:

  • Surgical resection must have been completed. Note: Participants who have had only had segmentectomy or wedge resections are not eligible for randomisation.

  • Psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent.
  • History of another primary malignancy except for:

Malignancy treated with curative-intent and with no known active disease 5 years before the first dose of durvalumab and of low potential risk for recurrence.

Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease.

Adequately treated carcinoma in situ without evidence of disease.

  • History of leptomeningeal carcinomatosis.

- Receipt of live attenuated vaccine within 30 days prior to the first dose of durvalumab.

Note: Patients in the ADOPT-lung trial, should not receive live vaccine whilst receiving durvalumab and for up to 30 days after the last dose.

Concurrent enrolment in another interventional clinical trial.

  • Known allergy or suspected hypersensitivity to durvalumab or its excipients.
  • Judgment by the investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions, and requirements.
  • Female patients who are pregnant or in the period of lactation.
  • Female patients of childbearing potential and sexually active men who are not willing to use a highly effective contraceptive method during the trial until at least 90 days after the last dose of protocol treatment.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Disease-free survival (DFS)
Time Frame: From the date of randomisation until last patient last visit (approximately 60 months after randomisation of the first patient)

Assessed in the adjuvant treatment phase.

DFS is defined as the time from the date of randomisation until disease recurrence (including loco-regional recurrence, a distant (metastatic) recurrence or a second primary) or death from any cause. Censoring (for patients without recurrence/death) will occur at the date of last tumour assessment. Patients without a post-randomisation tumour assessment will be censored at the date of randomisation (plus 1 day). DFS will be assessed in patients without pCR (primary endpoint), as well as in patients with pCR (secondary endpoint) and in patients with/without ctDNA clearance (secondary endpoints).
From the date of randomisation until last patient last visit (approximately 60 months after randomisation of the first patient)

Secondary Outcome Measures

Assessed in the adjuvant treatment phase (after randomisation).

DFS is defined as the time from the date of randomisation until disease recurrence (including loco-regional recurrence, a distant (metastatic) recurrence or a second primary) or death from any cause. Censoring (for patients without recurrence/death) will occur at the date of last tumour assessment. Patients without a post-randomisation tumour assessment will be censored at the date of randomisation (plus 1 day). DFS will be assessed in patients without pCR (primary endpoint), as well as in patients with pCR (secondary endpoint) and in patients with/without ctDNA clearance (secondary endpoints).

Assessed in the adjuvant treatment phase (after randomisation).

OS is defined as the time from the date of randomisation until death from any cause. Censoring (for patients who are not reported as having died) will occur at the date when they were last known to be alive.

Time Frame: From the date of randomisation until last patient last visit (approximately 60 months after randomisation of the first patient)

Assessed in the adjuvant treatment phase (after randomisation).

All safety parameters will be summarised in tables to evaluate the toxicity/safety profile of the protocol treatment based on:

  • Adverse events according to CTCAE v5.0 (any-cause as well as treatment-related) including adverse events leading to dose interruptions, withdrawal of protocol treatment, and death.
