Details and patient eligibility

About

This study is testing the investigational drug, cetuximab, in combination with different chemotherapy drugs for lung cancer. The aim of the study is to determine which of the drug combinations looks most promising and should be tested further. The study will also look at what side effects may occur.

Enrollment: 601 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

601 participants in 3 patient groups

Paclitaxel, Carboplatin, Cetuximab (Arm A)

Active Comparator group

Description:

Patients with squamous or non-squamous histologies will receive carboplatin and paclitaxel for a minimum of four and a maximum of six 21-day cycles, plus cetuximab, and then enter a maintenance phase with single-agent cetuximab. Cetuximab will be given on Day 1, and weekly during chemotherapy, followed by biweekly administration during the maintenance period. The choice of delivering four, five or six cycles of chemotherapy is at the investigator's discretion.

Treatment:

Drug: Paclitaxel

Drug: Cetuximab

Drug: Carboplatin

Platinum, Gemcitabine, Cetuximab (Arm B)

Active Comparator group

Description:

Patients with squamous or non-squamous histologies will receive gemcitabine with either carboplatin or cisplatin for a minimum of four and a maximum of six 21-day cycles, plus cetuximab, and then enter a maintenance phase with single-agent cetuximab. Cetuximab will be given on Day 1, and weekly during chemotherapy, followed by biweekly administration during the maintenance period. The choice of delivering four, five or six cycles of chemotherapy is at the investigator's discretion. The choice of platinum-based chemotherapy is also at the investigator's discretion.

Treatment:

Drug: Gemcitabine

Drug: Cetuximab

Drug: Cisplatin

Drug: Carboplatin

Platinum, Pemetrexed, Cetuximab (Arm C)

Active Comparator group

Description:

Patients with squamous histology will receive pemetrexed and either carboplatin or cisplatin for a minimum of four and a maximum of six 21-day cycles, plus cetuximab, and then enter a maintenance phase with single-agent cetuximab. Cetuximab will be given on Day 1, and weekly during chemotherapy, followed by biweekly administration during the maintenance period. The choice of delivering four, five or six cycles of chemotherapy is at the investigator's discretion. The choice of platinum-based chemotherapy is also at the investigator's discretion. Patients with non-squamous histology are not eligible for this arm.

Treatment:

Drug: Cetuximab

Drug: Cisplatin

Drug: Carboplatin
