PURPOSE: This multicenter, phase II clinical trial was conducted to evaluate the activity of the combination of docetaxel and exisulind in advanced non-small cell lung cancer (NSCLC) patients who failed a prior platinum-containing regimen. PATIENTS AND METHODS: Patients with measurable disease and adequate organ function received exisulind (250 mg) given orally, twice daily, and docetaxel (36 mg/m) administered intravenously on days 1, 8, and 15 of a 4-week cycle for up to six cycles. In the absence of disease progression or intolerable side effects, patients continued taking 250 mg of exisulind orally, twice daily. RESULTS: Thirty-three patients (median age 60 years; range 34-77; median performance status 1) were enrolled. There were no objective responses documented. Sixteen patients [48%, 95% confidence interval (CI): 31%-66%] had stable disease after 8 weeks of treatment. Median progression-free survival (PFS) was 2.1 months (95% CI: 1.5-3.2 months); median overall survival time was 8.0 months (range 0.2-25.9 months). Toxicity was moderate, with dose adjustment for adverse event/toxicity required for docetaxel or exisulind in 13 (39.3%) patients. Grade 3/4 lymphopenia, neutropenia, and anemia occurred in 48.5%, 12.1%, and 9.1% of patients, respectively. Grade 3 or greater toxicity was seen in 12.1%, 6.1%, and 3% of patients for nausea/vomiting, dyspnea, and abdominal pain, respectively. CONCLUSIONS: Treatment with exisulind and weekly docetaxel was not active in NSCLC patients who failed a prior platinum-containing regimen. Further study of this combination does not seem warranted.
