Phase I/II study of cisplatin combined with weekly paclitaxel in patients with advanced non-small-cell lung cancer.

ABSTRACT: To determine the maximum-tolerated dose (MTD) and the recommended dose (RD) of paclitaxel administered weekly with a fixed dose of cisplatin, and to assess the toxicity and activity of this combination, we conducted a phase I/II trial in patients with advanced non-small-cell lung cancer (NSCLC). In this study, patients with stage IIIB/IV NSCLC were eligible. Paclitaxel, at a starting dose of 40 mg x m(-2) week(-1) on days 1, 8, and 15, was combined with a fixed dose of cisplatin 80 mg x m(-2) on day 1. Chemotherapy was given in a 4-week cycle. In this phase I/II study, 38 patients were enrolled. Dose-limiting toxicities (DLT) were neutropenia, fatigue, and omission of treatment due to leucopenia, thrombocytopenia, or febrile neutropenia. The MTD and RD were estimated to be 70 mg x m(-2). Of the 37 assessable patients, 23 had a partial response and one had a complete response. Overall response rate was 62.1% (95% confidence interval (CI): 46.5-77.7%). The progression-free survival, the median survival time, and the 1-year survival rate were 5.5 months, 13.7 months, and 56.9%, respectively. This regimen is tolerable and very active against advanced NSCLC, and its efficacy should be confirmed in a phase III study.

Weekly albumin-bound paclitaxel/cisplatin versus gemcitabine/cisplatin as first-line therapy for patients with advanced non-small-cell lung cancer: A phase II open-label clinical study.

Project description:ObjectiveThe aim of this trial was to compare both the efficacy and the safety of a weekly nanoparticle albumin-bound paclitaxel (nab-paclitaxel) plus cisplatin vs. gemcitabine plus cisplatin in patients with advanced non-small-cell lung cancer (NSCLC).MethodsA total of 84 participants received either 100 mg/m2 nab-paclitaxel each week on d 1, 8 and 15 of a 28 day cycle, as well as cisplatin 75 mg/m2 on d 1 every three weeks (nab-TP arm); or gemcitabine 1,000 mg/m2 on d 1 and 8, plus cisplatin 75 mg/m2 on d 1 every three weeks (GP arm). The primary end point was progression-free survival (PFS). The secondary end points were overall response rate (ORR) and overall survival (OS).ResultsAccording to our analysis, the median PFS was 4.8 months for the nab-TP arm vs. 5.2 months for the GP arm (P=0.55). Analysis showed the median OS was 14.6 months for participants who were in the nab-TP arm vs. 15.1 months for those in the GP arm (P=0.94). Besides, nab-TP showed OS advantages over GP in patients harboring epidermal growth factor receptor (EGFR) mutation (26.7 vs. 15.3 months, P=0.046) and patients with a performance status of 0 (23.5 vs. 14.7 months, P=0.020). It was found that incidences of drug-related grade 3 or 4 toxicities were comparable between the two treatment arms.ConclusionsTherefore, it can be seen that weekly nab-TP treatment has a similar efficacy and tolerability to GP treatment for patients who are undergoing their first-line treatment for NSCLC. It could be that survival differences among platinum doublets in the context of both EGFR mutation and performance status have the potential to be the basis for our further clinical trials.

A randomised phase II study of weekly paclitaxel or vinorelbine in combination with cisplatin against inoperable non-small-cell lung cancer previously untreated.

Project description:Phase II studies have suggested that weekly paclitaxel has a higher response rate and better toxicity profile than the conventional schedule of once every 3 or 4 weeks. Our aim was to evaluate the efficacy of weekly paclitaxel plus cisplatin (PC) vs vinorelbine plus cisplatin (VC) in chemonaïve non-small-cell lung cancer (NSCLC) patients. From October 2000 to May 2002, 140 patients were enrolled. The treatment dose was P 66 mg m(-2) intravenous infusion (i.v.) on days 1, 8, and 15, and C 60 mg m(-2) i.v. on day 15, or V 23 mg m(-2) i.v. on days 1, 8, and 15, and C 60 mg m(-2) i.v. on day 15, every 4 weeks. In all, 281 cycles of PC and 307 cycles of VC were given to the patients in the PC and VC arms, respectively. There were 26 partial responses and one complete response (overall 38.6%) in the PC arm, and no complete responses, but 27 partial responses (overall 38.6%) in the VC arm. Myelosuppression was more common in the VC arm (P<0.001). Peripheral neuropathy and myalgia were significantly more common in the PC arm (P<0.001). The median time to disease progression was 6 months in the PC arm and 8.4 months in the VC arm (P=0.0344). The median survival time was 11.7 months in the PC arm and 15.4 months in the VC arm (P=0.297). We concluded that weekly PC is not suggested for NSCLC patients due to the relatively shorter progression-free survival and more common nonhaematological toxicities.

Randomised phase III trial of irinotecan combined with cisplatin for advanced non-small-cell lung cancer.

Project description:To determine a standard combination chemotherapy for patients with advanced non-small-cell lung cancer (NSCLC), we conducted a phase III trial of irinotecan (CPT-11) to test the hypotheses that CPT-11+cisplatin is superior to cisplatin+vindesine and that CPT-11 monotherapy is not inferior to cisplatin+vindesine. A total of 398 patients with previously untreated NSCLC were randomised to receive cisplatin+CPT-11 (CPT-P), cisplatin+vindesine (VDS-P) or CPT-11 alone (CPT). In the CPT-P arm, CPT-11 60 mg m(-2) was administered on days 1, 8 and 15, and cisplatin 80 mg m(-2) was administered on day 1. In the VDS-P arm, cisplatin 80 mg m(-2) was administered on day 1, and vindesine 3 mg m(-2) was administered on days 1, 8 and 15. In the CPT arm, CPT-11 100 mg m(-2) was administered on days 1, 8 and 15. The median survival time was 50.0 weeks for patients on CPT-P, 45.6 weeks for those on VDS-P and 46.0 weeks for those on CPT (P=0.115, CPT-P vs VDS-P; P=0.089, CPT vs VDS-P), and the hazard ratio was 0.85 (95% confidence interval (CI): 0.65-1.11) for CPT-P vs VDS-P and 0.83 (0.64-1.09) for CPT vs VDS-P. The response rate was 43.7% for patients on CPT-P, 31.7% for those on VDS-P and 20.5% for those on CPT. Major adverse reactions were grade 4 neutropenia observed in 37, 54 and 8% of the patients on CPT-P, VDS-P and CPT, respectively; and grades 3 and 4 diarrhoea observed in 12, 3 and 15% of the patients, respectively. CPT-P therapy produces comparable survival to VDS-P in patients with advanced NSCLC. CPT-11 monotherapy is not inferior to VDS-P in terms of survival. The CPT-11-containing regimen is one of the most efficacious and well tolerated in the treatment of advanced NSCLC.

A Phase II study of pulse dose imatinib mesylate and weekly paclitaxel in patients aged 70 and over with advanced non-small cell lung cancer.

Project description:In non-small cell lung cancer (NSCLC), interstitial hypertension is a barrier to chemotherapy delivery, and is mediated by platelet derived growth factor receptor (PDGFR). Antagonizing PDGFR with imatinib may improve intra-tumoral delivery of paclitaxel, increasing response rate (RR).This single-stage, open-label phase II study evaluated pulse dose imatinib and weekly paclitaxel in elderly patients with advanced NSCLC. Eligible patients were aged ? 70 with untreated, stage IIIB-IV NSCLC and ECOG performance status 0-2. Primary endpoint was RR. Secondary endpoints included median progression free and overall survival (PFS, OS) and correlatives of PDGFR pathway activation. Baseline Charlson Comorbidity Index (CCI) and Vulnerable Elder Survey-13 (VES-13) were correlated with outcomes.Thirty-four patients with median age 75 enrolled. Eleven of 29 (38%) were frail by VES-13 score. Overall RR was 11/34 (32%; 95% CI 17%-51%), meeting the primary endpoint. Median PFS and OS were 3.6 and 7.3 months, respectively. High tumoral PDGF-B expression predicted inferior PFS. Frail patients by VES-13 had significantly worse median PFS (3.2 vs. 4.5 months; p=0.02) and OS (4.8 vs. 12 months; p=0.02) than non-frail.The combination of imatinib and paclitaxel had encouraging activity as measured by the primary endpoint of RR. However, PFS and OS were typical for elderly patients treated with single agent chemotherapy and the regimen is not recommended for further study. Adjunct imatinib did not overcome the established association of tumoral PDGF-B expression with inferior PFS. VES-13 was a powerful predictor of poor survival outcomes. Frailty should be further studied as a predictor of non-benefit from chemotherapy.ClinicalTrials.gov NCT01011075.

Weekly paclitaxel and cisplatin as neoadjuvant chemotherapy with locally advanced breast cancer: a prospective, single arm, phase II study.

Project description:There was little evidence of weekly cisplatin regimen either for the locally advanced breast cancer or the metastatic setting. We aimed to evaluate that whether the combination of weekly paclitaxel and cisplatin could improve the efficacy of the neoadjuvant treatment for patients with locally advanced breast cancer. Patients with histologically confirmed large operable breast cancer received paclitaxel 80mg/m2 by weekly for 16 weeks and weekly cisplatin 25mg/m2 on day 1, 8 and 15, out of every 28 days for 4-week cycles. Trastuzumab was allowed for HER2-positive disease as weekly continuous regimen. The primary endpoint was locoregional total pathological complete response (tpCR) in breast and axilla lymph nodes after neoadjuvant treatment. One hundred and thirty-one patients were included in the study, among which 34.4% (45/131) patients achieved tpCR. Rate of pathological complete response (pCR) in the breast was 44.3% and the rate of near-pCR in breast was 48.1%. A significantly higher proportion of tpCR was seen in patients with triple negative breast cancer (64.7%, p = 0.003) and HER2 positive (non-luminal) cancer (52.4%, p = 0.018) compared with those who had luminal type tumors (24.7%). At multivariate analysis, negative estrogen receptor and high ki67 level independently predicted a better response. The most frequent toxicities were anemia, leukopenia and peripheral sensory neuropathy. Neoadjuvant chemotherapy by weekly paclitaxel and cisplatin combination was highly effective and tolerated in this study, especially in the triple negative and HER2 positive tumors.

Randomized phase II trial comparing carboplatin plus weekly paclitaxel and docetaxel alone in elderly patients with advanced non-small cell lung cancer: north japan lung cancer group trial 0801.

Project description:BACKGROUND: Standard first-line chemotherapy for elderly non-small cell lung cancer (NSCLC) patients has been monotherapy with vinorelbine or gemcitabine. Docetaxel has also been considered as an alternative option for the elderly population in Japan. We have previously demonstrated the high efficacy of carboplatin plus weekly paclitaxel for elderly NSCLC patients. Consequently, we conducted a randomized phase II study to select the proper regimen for a future phase III trial. METHODS: Eligible patients were aged 70 years or older with newly diagnosed advanced NSCLC. Patients were randomly assigned either to a combination of carboplatin (area under the curve: 6 mg/mL per minute) with weekly paclitaxel (70 mg/m²) (CP regimen) or to single-agent docetaxel (60 mg/m²). The primary endpoint of this study was objective response rate. Secondary endpoints were progression-free survival, overall survival, and toxicity profile. RESULTS: Among 83 eligible patients (41 to CP, 42 to docetaxel), the objective response rates were 54% (95% confidence interval: 39%-69%) and 24% (95% confidence interval: 11%-37%) and median progression-free survival was 6.6 months and 3.5 months in the CP arm and the docetaxel arm, respectively. Severe neutropenia, febrile neutropenia, and nausea were significantly frequent in the docetaxel arm, whereas toxicities in the CP arm were generally moderate. One treatment-related death was observed in the docetaxel arm. CONCLUSION: The CP regimen achieved higher activity with less toxicity than single-agent docetaxel. Considering the results of this phase II trial and the IFCT-0501 trial, we have selected the CP regimen for a future phase III trial in elderly patients with advanced NSCLC.

ERCC1 Expression-Based Randomized Phase II Study of Gemcitabine/Cisplatin Versus Irinotecan/Cisplatin in Patients with Advanced Non-small Cell Lung Cancer.

Project description:PurposeWe evaluated the clinical utility of excision repair cross-complementation group 1 (ERCC1) expression as a predictive biomarker for platinum-based chemotherapy in advanced non-small cell lung cancer (NSCLC).Materials and methodsEligible patients were randomly assigned to the GP (gemcitabine 1,250 mg/m2 on days 1 and 8, and cisplatin 75 mg/m2 on day 1 every 3 weeks) or IP (irinotecan 65 mg/m2 and cisplatin 30 mg/m2 on days 1 and 8 every 3 weeks) arm. The primary goal of this study was to compare the response rate (RR) of the GP and IP arms according to the ERCC1 expression level.ResultsA total of 279 patients were randomly assigned to the GP (n=139) and IP (n=140) arms, among which 63% were ERCC1-positive and 268 patients were assessable for the RR. The GP and IP arms did not differ significantly with respect to the RR (29.8% vs. 27.0%, respectively; p=0.082), median progression-free survival (PFS; 4.5 months vs. 3.9 months, respectively; p=0.117), and overall survival (OS; 16.5 months vs. 16.7 months, respectively; p=0.313). When comparing the efficacy between the ERCC1-positive and ERCC1-negative groups, there was no significant difference in the RR (GP, 28.2% vs. 32.6%, respectively, p=0.509; IP, 30.2% vs. 21.6%, respectively, p=0.536), median PFS (GP, 4.6 months vs. 5.0 months, respectively, p=0.506; IP, 3.9 months vs. 3.7 months, respectively, p=0.748), or median OS (GP, 18.6 months vs. 11.9 months, respectively, p=0.070; IP, 17.5 months vs. 14.0 months, respectively, p=0.821).ConclusionImmunohistochemical analysis of the ERCC1 expression level did not differentiate the efficacy of platinum-based chemotherapy in advanced NSCLC.

Randomised phase II study comparing dose-escalated weekly paclitaxel vs standard-dose weekly paclitaxel for patients with previously treated advanced gastric cancer.

Project description:BackgroundThis randomised phase II trial compared dose-escalated weekly paclitaxel (wPTX) vs standard-dose wPTX for patients with previously treated advanced gastric cancer (AGC).MethodsNinety patients were randomised to a standard dose of wPTX (80 mg m(-2)) or an escalated dose of wPTX (80-120 mg m(-2)) to assess the superiority of overall survival (OS) with a one-sided alpha error of 0.3 and a power of 0.8.ResultsThe median OS showed a trend towards longer survival in the dose-escalated arm (11.8 vs 9.6 months; hazard ratio (HR), 0.75; one-sided P=0.12), although it was statistically not significant. The median progression-free survival (PFS) was significantly longer in the dose-escalated arm (4.3 vs 2.5 months, HR, 0.55; P=0.017). Objective response rate was 30.3% with dose escalation and 17.1% with standard dose (P=0.2). The frequency of all grades of neutropenia was significantly higher with dose escalation (88.7% vs 60.0%, P=0.002); however, no significant difference was observed in the proportion of patients experiencing grade 3 or more (40.9% vs 31.1%, P=0.34).ConclusionDose-escalated wPTX in patients with pretreated AGC met our predefined threshold of primary end point, OS (P<0.3); however, it did not show a significantly longer OS. Progression-free survival was significantly better with dose escalation.

Prospective randomized study comparing concomitant chemoradiotherapy using weekly cisplatin & paclitaxel versus weekly cisplatin in locally advanced carcinoma cervix.

Project description:BackgroundTo evaluate the benefit with the addition of paclitaxel to cisplatin-based concurrent chemoradiotherapy (C-CRT) for the treatment of locally advanced carcinoma of the uterine cervix in terms of local control, disease free survival (DFS) and overall survival (OS).MethodsFrom 1/7/2011 to 31/5/2012, 81 women (median age of 50 years) with newly diagnosed, histopathologically proven carcinoma cervix with FIGO stages IIA to IIIB were randomized to two arms-cisplatin 40 mg/m(2)/week for 5 weeks was given in single agent cisplatin (control arm), while cisplatin 30 mg/m(2)/week and paclitaxel 50 mg/m(2)/week for 5 weeks were given in cisplatin and paclitaxel (study arm). External beam radiotherapy (EBRT) was delivered to a total dose of 50 Gray (Gy) in 25 fractions (#) followed by intracavitary (I/C) brachytherapy or supplement EBRT at 20 Gy/10# with 2 cycles of respective chemotherapy. This prospective trial was registered with clinicaltrials.gov (NCT01593306).ResultsPatients (n=81) had a maximum follow up of 36 months with a median follow up of 29 months. At first follow up study arm showed complete response in 84% vs. 75.6% in control arm (P=0.4095). An increase in toxicities was observed in the study arm in comparison to the control arm in terms of haematological grade II (35% vs. 12.2%), gastrointestinal (GI) grade III (20% vs. 7.4%) and GI grade IV (12.5% vs. 2.4%) toxicities. At median follow-up, the study arm demonstrated enhanced outcomes over the control arm in terms of DFS (79.5% vs. 64.3%; P=0.07) and OS (87.2% vs. 78.6%; P=0.27).ConclusionsDespite the expected increase in manageable toxicities, these early results reveal promise with the inclusion of paclitaxel into the standard cisplatin based chemoradiation regime. Larger multi-institutional studies are justified to confirm a potential for the enhancement of response rates and survival.

Randomized phase II study of carboplatin and paclitaxel with either linifanib or placebo for advanced nonsquamous non-small-cell lung cancer.

Project description:PurposeLinifanib, a potent, selective inhibitor of vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) receptors, has single-agent activity in non-small-cell lung cancer (NSCLC). We evaluated linifanib with carboplatin and paclitaxel as first-line therapy of advanced nonsquamous NSCLC.Patients and methodsPatients with stage IIIB/IV nonsquamous NSCLC were randomly assigned to 3-week cycles of carboplatin (area under the curve 6) and paclitaxel (200 mg/m(2)) with daily placebo (arm A), linifanib 7.5 mg (arm B), or linifanib 12.5 mg (arm C). The primary end point was progression-free survival (PFS); secondary efficacy end points included overall survival (OS) and objective response rate.ResultsOne hundred thirty-eight patients were randomly assigned (median age, 61 years; 57% men; 84% smokers). Median PFS times were 5.4 months (95% CI, 4.2 to 5.7 months) in arm A (n = 47), 8.3 months (95% CI, 4.2 to 10.8 months) in arm B (n = 44), and 7.3 months (95% CI, 4.6 to 10.8 months) in arm C (n = 47). Hazard ratios (HRs) for PFS were 0.51 for arm B versus A (P = .022) and 0.64 for arm C versus A (P = .118). Median OS times were 11.3, 11.4, and 13.0 months in arms A, B, and C, respectively. HRs for OS were 1.08 for arm B versus A (P = .779) and 0.88 for arm C versus A (P = .650). Both linifanib doses were associated with increased toxicity, including a higher incidence of adverse events known to be associated with VEGF/PDGF inhibition. Baseline plasma carcinoembryonic antigen/cytokeratin 19 fragments biomarker signature was associated with PFS improvement and a trend toward OS improvement with linifanib 12.5 mg.ConclusionAddition of linifanib to chemotherapy significantly improved PFS (arm B), with a modest trend for survival benefit (arm C) and increased toxicity reflective of known VEGF/PDGF inhibitory effects.
