Single Arm on the Tolerability of Weekly Nab-paclitaxel

This will be a non-randomized phase II study evaluating the safety and efficacy of weekly nab-paclitaxel for second-line treatment in 42 elderly patients, who are 70 years of age or greater with non-small cell lung cancer (NSLC). Patients will be required to have progressed on a single prior regimen. Nab-paclitaxel 100mg/m2 will be administered intravenously, weekly for 3 weeks of every 4-week cycle. After every two cycles of therapy, imaging will be performed to assess for response. Patients will be eligible to continue receiving therapy until the time of disease progression. Primary Objectives To evaluate the tolerability of weekly nab-paclitaxel in older adults with advanced lung cancer who have progressed on at least 1 prior regimen after 6 cycles or 3 weeks after discontinuation of treatment, for those who come off treatment earlier. Secondary Objectives To estimate overall survival To estimate progression-free survival To estimate the response rate Correlative Objectives To explore baseline components of the Geriatric Assessment (GA) as predictors of chemotherapy tolerance and overall survival To explore the use of p16 measurements in the elderly as predictors of chemotherapy tolerance and overall survival To explore the impact of weekly nab-paclitaxel treatment on quality of life, as measured by Lung Cancer Symptom Scale (LCSS) and Functional Assessment of Cancer Therapy-Lung (FACT-L).
