Treatment Plan

Patients in this global trial will be stratified based on performance status, sex, stage, and PET scan use and will be randomized in a 1:1 ratio to either the pemetrexed regimen or the control arm, as shown in Figure 1.

Design of the PROCLAIM study.

Patients on the pemetrexed arm will be scheduled to receive 3 cycles of pemetrexed and cisplatin at doses of 500 mg/m2 and 75 mg/m2 respectively on days 1, 22, and 43 of radiation, to be followed after a 3-5 week recovery from the completion of radiation by consolidation therapy with pemetrexed 500 mg/m2 every 21 days for 4 cycles. Patients on the control arm will receive chemotherapy with etoposide 50 mg/m2 days 1-5 and 29-33 and cisplatin 50 mg/m2 days 1, 8, 29, and 36 of radiation therapy. Following the 3-5 week recovery after radiation, patients will commence 1 of 3 platinum doublet therapy consolidation programs for a maximum of 2 cycles of a regimen of their physician’s choice: etoposide and cisplatin as given with radiation; vinorelbine and cisplatin at doses of 30 mg/m2 days 1, 8, 22, and 29 with cisplatin 75 mg/m2 days 1 and 22; or paclitaxel at dose of 200 mg/m2 and carboplatin (AUC = 6) both on days 1 and 22.

All patients will be scheduled to receive 66 Gy in 33 fractions only to known disease (‘involved fields’) administered 5 days weekly. All patients should have at least 3-dimensional radiation treatment plans. Four-dimensional CT imaging and use of strategies to account for tumor motion will be permitted.

Following completion of therapy, patients will commence scheduled follow-up at 6, 9, and 12 months from study entry; every 4 months during year 2; and every 6 months from years 3-5. Computed tomography scans of the chest and abdomen will be obtained with each visit and pulmonary function tests performed at 6, 12, and 24 months.
