Efficacy and safety of rh-endostatin combined with docetaxel in second-line or intolerant toxicity for first-line treatment in patients with advanced non-small cell lung cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To analyze the efficacy and safety of combination of rh-endostatin (Endostar) with docetaxel treatment on patients of non-small cell lung cancer (NSCLC) who presented PD or intolerable toxicity in/after first-line chemotherapy.</p><p><b>METHODS</b>A randomized, double-blind, placebo-controlled and multi-center clinical trial was conducted. Patients with stage IIIB/IV of NSCLC experienced previous chemotherapy of one-regimen were screened for this trial. A total of 68 cases were included in this study. Single docetaxel and that combined with endostar were conducted in two arms. The response, time to progression (TTP) and adverse effects were observed in both arms.</p><p><b>RESULTS</b>The objective response rate (ORR) and clinical benefit rate (CBR) were 0 and 62.5% in the combined arm, along with 0 and 53.3% in the single docetaxel arm, with a non-significant difference between the two groups (all P > 0.05), respectively. The median TTPs in the combined and single docetaxel arms were 2.63 and 2.07 months, respectively (P = 0.079). The median TTPs of the participants with progressive disease (PD) after first-line chemotherapy were 1.33 and 1.67 months in the combined and single docetaxel arms, respectively (P = 0.946). The median TTPs of the participants with intolerant adverse effects in first-line chemotherapy were 4.70 months and 3.17 months in the combined and single docetaxel arms, respectively (P = 0.070). The median TTPs of the patients with SD after 2 therapeutic cycles in the combined and single docetaxel arms were 6.23 months and 3.27 months, respectively (P = 0.040). The differences between two arms were non-significant in adverse, serious adverse and cardiovascular adverse effects (all P > 0.05).</p><p><b>CONCLUSIONS</b>Endostar may prolong TTP in patients with advanced NSCLC benefited from docetaxel treatment without increased toxicities.</p>

Randomized phase II trial on escalated doses of Rh-endostatin (YH-16) for advanced non-small cell lung cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the response rate (RR), time to tumor progression (TTP), quality of life (QOL) and adverse reaction in the treatment of pretreated advanced non-small cell lung cancer (NSCLC) using escalated doses of rh-endostatin (YH-16), and to determine the optimal dose for clinical application.</p><p><b>METHODS</b>In this phase II randomized, controlled, multicenter trial, the patients were randomly divided into two groups to receive daily 3 hours intravenous infusion of either 7.5 mg x m(-2) or 15 mg/m(2) YH-16 for 28 days.</p><p><b>RESULTS</b>Totally, 68 patients were entered and 60 patients were evaluable. There were no differences in RR (3.0% in both groups, P > 0.05), median TTP (ITT: 60 days versus 71 days, P > 0.05), QOL and incidence rate of adverse reactions (48.6% versus 38.7%, P > 0.05). No significant unexpected adverse events were observed.</p><p><b>CONCLUSION</b>Rh-endostatin may have anti-tumor activity with high clinical benefit rate and is well tolerated in pretreated advanced NSCLC patients. The dose of 7.5 mg x (m(2))(-1) x d(-1) is clinically recommended.</p>
