Trial of Poor Performance Status Patients (ToPPS)

This randomized, Phase II trial will evaluate three treatment regimens in patients with previously untreated stage IIIB/IV Non-Small Cell Lung Cancer (NSCLC) and a performance status (PS) of 2. Patients will be randomized to either pemetrexed alone, pemetrexed and bevacizumab, or pemetrexed, carboplatin, and bevacizumab in a 1:1:1 fashion. All 3 regimens should be tolerable in poor performance status patients with advanced NSCLC. The 3-drug regimen (pemetrexed/carboplatin/bevacizumab) has been modified by lowering the dose of carboplatin, in order to minimize myelosuppression. This trial will be conducted at multiple study sites.
