Details and patient eligibility

About

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.

Full 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.

Enrollment: 97 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
