Brief summary

This is an open-label, phase II, multi-centre clinical trial. 97 Patients with stage IIIA and IIIB non-small cell lung cancer will be enrolled. The treatment is Atezolizumab + Paclitaxel + Carboplatin 3 cycles as neoadjuvant/induction treatment. After the induction treatment every patient will be evaluated by a multidisciplinary team in each participant hospital to decide if the patient is candidate for surgery or not. Depending on the decision each patient will be treated in a different way. The primary objective is to evaluate the Progression free survival (PFS). The total trial duration will be 10 years approximately. Patient accrual is expected to be completed within 2 years. Two years of treatment, 5 years of follow up, and 4-6 months of close-out.

Detailed description

The study ATHENEA is a phase II clinical trial intending to enroll 97 patients, who will receive Atezolizumab + Paclitaxel + Carboplatin as induction/neoadjuvant treatment. After the induction treatment all patients will be evaluated by a multidisciplinary team in each participant hospital to decide if the patient is candidate for surgery or not. Depending on the decision each patient will be treated in a different way. The study is an open-label, phase II, multicenter clinical trial for previously untreated adult patients with stage to IIIA and IIIB non-small cell lung cancer. The primary objective is to evaluate the Progression free survival (PFS) in the intent-to-treat population. Progression free survival (PFS) defined as the time from initiation of treatment to the occurrence of disease progression or death. The total trial duration will be 10 years approximately. Approval-start up: 4-6 months. Patient accrual is expected to be completed within 2 years. Two years of treatment, 5 years of follow up, and close-out: 4-6 months. The study will end once survival follow-up has concluded.

Interventions

DRUGAtezolizumab

Patients will receive atezolizumab administered by intravenous infusion in a monitored setting where there is immediate access to trained personnel and adequate equipment/medicine to manage potentially serious reactions.

DRUGPaclitaxel

Neoadjuvant / induction treatment: Atezolizumab Paclitaxel Carboplatin Neoadjuvant / induction treatment 3 cycles will be administered prior to the assessment for surgery. Route of administration Paclitaxel: Intravenous infusion. Guidelines of Paclitaxel administration: Paclitaxel must be administered by infusion over 3 hours in dextrose (D5W) or normal saline (NS). The concentration must not exceed 1.2 mg/ml.

DRUGCarboplatin

Neoadjuvant / induction treatment: Atezolizumab Paclitaxel Carboplatin\* \*Infusion according to the standard of each center Neoadjuvant / induction treatment 3 cycles will be administered prior to the assessment for surgery. Route of administration Carboplatin: Intravenous infusion. Guidelines of Carboplatin administration: According to the standard of each center.

Design outcomes

Primary

MeasureTime frameDescription
Progression-free survival (PFS)From the date of randomization until end of follow up, up to 60 months.Progression free survival (PFS) defined as the time from initiation of treatment to the occurrence of disease progression or death. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.

Secondary

MeasureTime frameDescription
Resectability rate (%)From the date of randomization until end of follow up, up to 60 months.Resectability rate defined as the percentage of patients resected divided by the total number of patients who received neoadjuvant treatment.
Pathological complete response (pCR)From the date of randomization until end of surgery, up to 6 monthsPathological complete response (pCR) is defined as the absence of residual viable tumor on hematoxylin and eosin evaluation of the complete resected specimen
Overall survival (OS)From the date of randomization until end of follow up, up to 60 months.Overall survival (OS) defined as the time which begins at the start of treatment and up to the time of death or last follow up
