INTRODUCTION: The aim of the study is to investigate the activity and safety of oral talactoferrin (TLF) plus carboplatin and paclitaxel (C/P) in patients with previously untreated stage IIIB/IV non-small cell lung cancer. METHODS:Patients (n = 110) were randomly assigned to receive C/P plus either TLF (C/P/T) or placebo (C/P/P). The primary objective of this exploratory study was assessment of confirmed response rate (RR) in the prospectively defined evaluable population with a one-tailed p = 0.05. Secondary objectives included assessment of progression-free survival (PFS), duration of response, overall survival (OS), and safety. RESULTS: The trial met the primary end point of improvement in confirmed RR in the prospectively defined evaluable population. Compared with the C/P/P group, RR increased in the C/P/T group by 18% (29-47%; p = 0.05) and 15% (27-42%; p = 0.08) in the evaluable and intent-to-treat populations, respectively. Compared with the C/P/P group, the C/P/T group had a longer median PFS (4.2 versus 7.0 months), OS (8.5 versus 10.4 months), and duration of response (5.5 versus 7.6 months), although the differences were not statistically significant. Adverse events (AEs) were consistent with C/P therapy. There were fewer total AEs (472 versus 569; two-tailed p = 0.003) and grade 3/4 AEs (78 versus 105; p = 0.05) in the C/P/T group compared with the C/P/P group. CONCLUSION:TLF, in combination with C/P, demonstrated an apparent improvement in RR, PFS, and OS in patients with previously untreated stage IIIB/IV non-small cell lung cancer and appears to enhance activity without significant additional toxicity. These results need to be confirmed in a phase III trial.
