Oral Topotecan

Purpose This open-label, randomized, multicenter, phase III study compared oral topotecan versus intravenous (IV) docetaxel in patients with previously treated non–small-cell lung cancer (NSCLC). Patients and Methods Patients with stage III or IV NSCLC, performance status ≤ 2, who had received only one prior chemotherapy regimen, were randomly assigned to treatment with oral topotecan 2.3 mg/m2/d on days 1 to 5 or IV docetaxel 75 mg/m2 day 1 every 21 days. Results A total of 829 patients were randomly assigned. In intent-to-treat analysis, 1-year survival rates were 25.1% with topotecan and 28.7% with docetaxel. The difference of −3.6% (95% CI, −9.59% to 2.48%) met the predefined criteria for noninferiority of topotecan relative to docetaxel because the lower limit of the 95% CI was above −10%. Median survival was 27.9 weeks with topotecan and 30.7 weeks with docetaxel. Although not statistically significant (log-rank P = .057), the higher survival rate with docetaxel was maintained across the entire treatment period. The median time to progression was 11.3 weeks with topotecan versus 13.1 weeks with docetaxel (log-rank P = .02). The overall response rate was 5% in each group. Grade 3/4 neutropenia occurred more frequently with docetaxel (60% v 50%). Grade 3/4 anemia and thrombocytopenia occurred more frequently with topotecan (26% v 10% and 26% v 7%, respectively). Conclusion Oral topotecan provides activity in the treatment of relapsed, locally advanced, unresectable NSCLC. Both regimens were well tolerated with differing safety profiles. Topotecan may provide an option for patients who desire an orally available treatment after relapse.

Oral Topotecan

Purpose This open-label, randomized, multicenter phase III study compared oral topotecan/intravenous cisplatin (TC) with intravenous (IV) etoposide/cisplatin (PE) in patients with untreated extensive-disease small-cell lung cancer (ED-SCLC). Patients and Methods A total of 784 patients were randomly assigned to either oral topotecan 1.7 mg/m2/d × 5 with IV cisplatin 60 mg/m2 on day 5 (n = 389) or IV etoposide 100 mg/m2/d × 3 with IV cisplatin 80 mg/m2 on day 1 (n = 395) every 21 days. Results Overall survival (primary end point) was similar between groups (P = .48; median: TC, 39.3 weeks v PE, 40.3 weeks). One-year survival was 31% (95% CI, 27% to 36%) in both groups and the difference of −0.03 (95% CI, −6.53 to 6.47) met the predefined criteria of ≤ 10% absolute difference for noninferiority of TC relative to PE. Response rates were similar between groups (TC, 63% v PE, 69%). Time to progression was slightly but statistically longer with PE (log-rank P = .02; median: TC, 24.1 weeks v PE, 25.1 weeks). The regimens were similarly tolerable. Grade 3/4 neutropenia occurred more frequently with PE (84% v 59%), whereas grade 3/4 anemia and thrombocytopenia occurred more frequently with TC (38% v 21% and 38% v 23%, respectively). Lung Cancer Symptom Scale scores were statistically better with PE, but the differences were small and of debatable clinical significance. Conclusion Oral topotecan with cisplatin provides similar efficacy and tolerability to the standard (etoposide with cisplatin) in untreated ED-SCLC and may provide greater patient convenience compared with intravenous etoposide and cisplatin.

Purpose A phase III study to determine whether a weekly docetaxel schedule improves the therapeutic index compared with the classic 3-weekly schedule. Patients and Methods Patients with stage IIIB-IV non–small-cell lung cancer (NSCLC) were randomly assigned to docetaxel 75 mg/m2 on day 1 every 3 weeks (3-weekly) and 35 mg/m2 on days 1, 8, and 15 (weekly) for ≤ eight cycles. End points included survival (primary), toxicity, and response. Results Of 215 patients enrolled, 208 (103 in the 3-weekly arm and 105 in the weekly arm) were assessable for response. At baseline, 24.5% of patients (51 out of 208) had received prior paclitaxel therapy and 43.3% of patients (90 out of 208) had been progression-free for more than 3 months after first-line therapy. After 12 months' follow-up, median survival was 6.3 months (95% CI, 4.68 to 7.84 months) with 3-weekly docetaxel and 9.2 months (95% CI, 5.83 to 12.59 months) with weekly docetaxel (P = .07) after a median of four (range, one to eight) and two (range, one to eight) treatment cycles, respectively. Overall, response rates were 12.6% v 10.5% with 3-weekly versus weekly docetaxel. Significantly fewer patients reported grade 3 to 4 toxicities with weekly docetaxel versus 3-weekly docetaxel (P ≤ .05). There were significantly lower rates of grade 3 to 4 anemia (P ≤ .05), leucopenia (P < .0001), and neutropenia (P ≤ .001) with weekly versus 3-weekly treatment. No grade 3 to 4 thrombocytopenia or mucositis was reported. Conclusion Weekly docetaxel 35 mg/m2 demonstrated similar efficacy and better tolerability than standard 3-weekly docetaxel 75 mg/m2 and can be recommended as a feasible alternative second-line treatment option for patients with advanced NSCLC.

PurposeCisplatin plus gemcitabine is a standard regimen for first-line treatment of advanced non–small-cell lung cancer (NSCLC). Phase II studies of pemetrexed plus platinum compounds have also shown activity in this setting.Patients and MethodsThis noninferiority, phase III, randomized study compared the overall survival between treatment arms using a fixed margin method (hazard ratio [HR] < 1.176) in 1,725 chemotherapy-naive patients with stage IIIB or IV NSCLC and an Eastern Cooperative Oncology Group performance status of 0 to 1. Patients received cisplatin 75 mg/m2on day 1 and gemcitabine 1,250 mg/m2on days 1 and 8 (n = 863) or cisplatin 75 mg/m2and pemetrexed 500 mg/m2on day 1 (n = 862) every 3 weeks for up to six cycles.ResultsOverall survival for cisplatin/pemetrexed was noninferior to cisplatin/gemcitabine (median survival, 10.3 v 10.3 months, respectively; HR = 0.94; 95% CI, 0.84 to 1.05). Overall survival was statistically superior for cisplatin/pemetrexed versus cisplatin/gemcitabine in patients with adenocarcinoma (n = 847; 12.6 v 10.9 months, respectively) and large-cell carcinoma histology (n = 153; 10.4 v 6.7 months, respectively). In contrast, in patients with squamous cell histology, there was a significant improvement in survival with cisplatin/gemcitabine versus cisplatin/pemetrexed (n = 473; 10.8 v 9.4 months, respectively). For cisplatin/pemetrexed, rates of grade 3 or 4 neutropenia, anemia, and thrombocytopenia (P ≤ .001); febrile neutropenia (P = .002); and alopecia (P < .001) were significantly lower, whereas grade 3 or 4 nausea (P = .004) was more common.ConclusionIn advanced NSCLC, cisplatin/pemetrexed provides similar efficacy with better tolerability and more convenient administration than cisplatin/gemcitabine. This is the first prospective phase III study in NSCLC to show survival differences based on histologic type.

Purpose Following a phase II trial in which pemetrexed-platinum demonstrated similar activity to that of historical etoposide-platinum controls, a phase III study was conducted to compare pemetrexed-carboplatin with etoposide-carboplatin for the treatment of extensive-stage small-cell lung cancer (ES-SCLC). Patients and Methods Chemotherapy-naive patients with ES-SCLC and an Eastern Cooperative Oncology Group performance status of zero to 2 were randomly assigned to receive pemetrexed-carboplatin (pemetrexed 500 mg/m2 on day 1; carboplatin at area under the serum concentration-time curve [AUC] 5 on day 1) or etoposide-carboplatin (etoposide 100 mg/m2 on days 1 through 3; carboplatin AUC 5 on day 1) every 3 weeks for up to six cycles. The primary objective of the study was noninferiority of pemetrexed-carboplatin overall survival with a 15% margin. Results Accrual was terminated with 908 of 1,820 patients enrolled after results of a planned interim analysis. In the final analysis, pemetrexed-carboplatin was inferior to etoposide-carboplatin for overall survival (median, 8.1 v 10.6 months; hazard ratio [HR],1.56; 95% CI, 1.27 to 1.92; log-rank P < .01) and progression-free survival (median, 3.8 v 5.4 months; HR, 1.85; 95% CI, 1.58 to 2.17; log-rank P < .01). Objective response rates were also significantly lower for pemetrexed-carboplatin (31% v 52%; P < .001). Pemetrexed-carboplatin had lower grade 3 to 4 neutropenia, febrile neutropenia, and leukopenia than etoposide-carboplatin; grade 3 to 4 thrombocytopenia was comparable between arms and anemia was higher in the pemetrexed-carboplatin arm. Conclusion Pemetrexed-carboplatin is inferior for the treatment of ES-SCLC. Planned translational research and pharmacogenomic analyses of tumor and blood samples may help explain the study results and provide insight into new treatment strategies.
