* * * * * * * * * * * * * * * * * * * * * * * A total of 43 thromboembolic events (TEEs) were reported. The difference between the NeoRecormon? and control groups was mainly due to an increased rate of non-serious vascular TEEs such as thrombophlebitis and deep vein thrombosis in the NeoRecormon? group. The percentage of patients who experienced a serious TEE was comparable between the two study arms. * Purpose To determine the effect of darbepoetin alfa (DA) on progression-free survival (PFS) and overall survival (OS) in patients with chemotherapy-induced anemia (CIA). Patients and Methods Two 16-week randomized, double-blind, placebo-controlled phase III studies of weekly DA in anemic patients with lung cancer (n 314) or lymphoproliferative malignancies (LPMs; n 344) undergoing chemotherapy were analyzed with prospectively defined long-term PFS and OS end points. Short-term effects of DA on PFS and OS were analyzed by including two additional 16-week dose-finding, double-blind, placebo-controlled studies in anemic patients with multiple tumor types (n 405) and LPMs (n 66). Results Median follow-up is 15.8 months (lung cancer) and 32.6 months (LPM). Median duration of PFS was comparable between DA and placebo: 5.1 months (95% CI, 4.1 to 6.9 months) versus 4.4 months (95% CI, 3.7 to 5.3 months) for lung cancer and 14.2 months (95% CI, 12.2 to 17.5 months) versus 15.9 months (95% CI, 13.1 to 19.0 months) for LPMs. The estimated hazard ratio (HR) of death related to DA use for lung cancer was 0.77 (95% CI, 0.59 to 1.01) and 1.26 (95% CI, 0.92 to 1.71) for LPMs. In the pooled analyses of all four studies (n 1,129), no differences in PFS or OS were observed between DA and placebo (HR 0.92; 95% CI, 0.78 to 1.07; and HR 0.95; 95% CI, 0.78 to 1.16, respectively). Conclusion Treatment with DA does not seem to influence PFS or OS in patients with CIA. Prospective, randomized clinical trials will provide additional insights into the effects of DA on PFS an
