About
This study aims to compare the one-year survival benefit of the association of cryoablation-pembrolizumab-pemetrexed-carboplatin versus pembrolizumab-pemetrexed-carboplatin in metastatic lung adenocarcinoma patients.
This is a multicenter, prospective, open-labeled, 2-arm comparative randomized (1:1) phase III trial.
Patients will be randomized with a 1:1 ratio into:
Pembrolizumab and pemetrexed-carboplatin will be prescribed and administered at the dose recommended by market authorization.
Cryoablation treatment should be performed within 6 weeks after the first administration of pembrolizumab. No treatment switching permitted.
Full description
Upon signature of the informed consent and verification of the screening results, eligible participants will be randomized between two therapeutic strategies:
Pembrolizumab treatment should begin no later than 7 days after randomization. The cryoablation treatment should be performed within 6 weeks after the first administration of pembrolizumab.
RECIST v1.1 tumour assessment:Tumour response will be defined and assessed as per the Response Evaluation Criteria in Solid Tumors (RECIST v1.1).
SAFETY :Patients will be evaluable for safety if they have received at least one treatment administration. Safety profile will be continuously followed during treatment up to 90 days after the last immunotherapy treatment administration or until the start of a new antitumor therapy or until 12 months of treatment, whichever occurs first.
STUDY PROCEDURES :
Blood sample will be collected at baseline (Day 1: before treatment initiation), Day 1 cycle 2 (Day 21 +/- 3 days), Day 1 cycle 3 (Day 42 +/- 3 days) and progression.
Patients will be asked to provide samples of biopsy tissue at screening (prior to anticancer agent with immunomodulatory activity treatment initiation), during treatment (day 42 +/- 3 days) and at disease progression as follows. Tumor biopsy at inclusion is optional if materiel archived fixed in formalin and embedded in paraffin of diagnostic biopsy is available.
All randomized patients will be followed up until death or the end of the follow-up period, defined as 36 months after randomization, whichever occurs first. For all patients, treatments regimen, tumor response during and/or after treatment, survival follow-up will be collected on study database:
