Dose Attenuated Chemotherapy in Compromised Patients With Lung Cancer

This is an open-label, non-randomized, single-center, phase II study to evaluate the efficacy, toxicity and, tolerability of pre-specified dose attenuated chemotherapy regimens in lung cancer patients with comorbidities. The investigator will indicate the rationale(s) for dose modification based on the subgroups of patients listed in the protocol. Patients may fit into multiple subgroups and this is accounted for in the prospectively defined dose reduction level as listed in the protocol. Prespecified doses by chemotherapeutic agent and dose level adjustment based on patient characteristics and comorbidities are listed in the protocol. Analyses will be stratified by treatment group 1-3 based on the treating physician's selected therapy.
