About this study

Official title: MELROSE: Phase 2 Study Evaluating MEchanisms of Resistance on Tumor Tissue and Liquid Biopsy in Patients With EGFR Mutated Nonpretreated Advanced Lung Cancer Receiving OSimErtinib Until and Beyond Radiological Progression : the MELROSE Trial

Osimertinib is an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that is selective for both EGFR-TKI sensitizing and T790M resistance mutations in patients with non-small-cell lung cancer.

The AURA 3 study (T790M-positive advanced non-small-cell lung cancer in progression after first-line EGFR-TKI therapy, shown that the median duration of progression-free survival was significantly longer with osimertinib than with platinum therapy plus pemetrexed (10.1 months vs. 4.4 months p<0.001).

In addition, clinical data show that patients with mutated EGFR NSCLC receiving osimertinib in first line, presented an objective response rate of 77 % with a disease control rate of 98 % and a median PFS was 19.3 months.

Finally, The FLAURA study randomized phase 3 study clearly demonstrated the superiority of osimertinib compared with erlotinib or gefitinib in EGFR mutated nonpretreated NSCLC (median PFS of 18.9 months versus 10.2 months).

However, several issues remain unknown or debated :

  • What are the mechanisms of resistance to osimertinib prescribed in first-line?
  • What are the consequences of prolonged exposure to osimertinib on the expression of markers of response to immunotherapy?
  • Is there an association between kinetic parameters of ctDNA (circulating tumor DNA) and prediction of response to osimertinib and/ or and prediction of therapeutic escape under osimertinib? In order to respond to all these questions, this phase II trial will be the first to systemically analyze the mechanisms of resistance to Osimertinib based on the analysis of biopsy, and collection of plasma from all patients during the course of treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TAGRISSO® 80mg (Osimertinib)Drug

    Oral administration of TAGRISSO® 80mg (Osimertinib) as a single daily dose until disease progression or unacceptable toxicity.

  • Tumor biopsiesGenetic

    Tumor biopsies performed at baseline and clinical progression will be processed (fixed) on site, and sent to Nantes University Hospital for analysis.

    The following analysis will be performed:

    1. Analyses performed on a regular basis, in order to allow subsequent inclusion in other clinical trials :
    • C797S testing (digital PCR)
    • MET amplification (dPCR/FISH)
    • Histological examination of the tissue sample (to identify small cell transformation)
    • Expression of proteins by immunohistochemistry: PD-L1 (Ventana SP263 antibody); CD73 ; CD4; CD8.
    1. At the end of inclusions, deep sequencing analysis to identify acquired mutations and copy number variations (amplifications).

  • ctDNA analysisGenetic

    ctDNA analysis by Collection of plasma (two 10-ml Streck tubes) at each time point indicated in the trial.

    These samples will be sent at room temperature by courier to the central laboratory (Nantes University Hospital). There they will be centrifuged, and plasma will be frozen (-80°C).

    Analyses :

    • Detection of the EGFR activating mutation in plasma at baseline By dPCR (characterization of patients enrolled)
    • Detection of the EGFR activating mutation at d7 and m1 by dPCR (early detection of response to osimertinib)
    • Analysis of the plasma samples collected at clinical progression in order to identify acquired mechanisms of resistance by NGS (and comparison with analysis of the biopsies).
    • Kinetics studies of the alterations

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 14 inclusion and 30 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: status not confirmed, as of the sponsor's last update on 28 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 sites in France. 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 phase mean?

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?

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03865511, which also lists 1 linked publication.

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 Feb 2024.
