Project description:BACKGROUND: Platinum-based doublet chemotherapy is the standard first-line treatment for advanced non-small cell lung cancer (NSCLC), but earlier studies have suggested that non-platinum combinations are equally effective and better tolerated. We conducted a national, randomised study to compare a non-platinum with a platinum combination. METHODS: Eligible patients had stage IIIB/IV NSCLC and performance status (PS) 0-2. Patients received up to three cycles of vinorelbine 60 mg m(-2) p.o.+gemcitabine 1000 mg m(-2) i.v. day 1 and 8 (VG) or vinorelbine 60 mg m(-2) p.o. day 1 and 8+carboplatin area under the curve=5 (Calvert's formula) i.v. day 1 (VC). Patients ≥75 years received 75% of the dose. Endpoints were overall survival, health-related quality of life (HRQoL), toxicity, and the use of radiotherapy. RESULTS: We randomised 444 patients from September 2007 to April 2009. The median age was 65 years, 58% were men and 25% had PS 2. Median survival was VG: 6.3 months; VC: 7.0 months, P=0.802. Vinorelbine plus carboplatin patients had more grade III/IV nausea/vomiting (VG: 4%, VC: 12%, P=0.008) and grade IV neutropenia (VG: 7%, VC: 19%, P<0.001). Infections, HRQoL and the use of radiotherapy did not differ significantly between the treatment groups. CONCLUSION: The two regimens yielded similar overall survival. The VG combination had only a slightly better toxicity profile.

Project description:The aim of this study was to assess whether a combination of gemcitabine (GEM) with either paclitaxel (PTX) or vinorelbine (VNR) could be more effective than GEM or PTX alone in elderly or unfit advanced non-small-cell lung cancer (NSCLC) patients. A total of 264 NSCLC patients aged >70 years with ECOG performance status (PS)< or =2, or younger with PS=2, were randomly treated with: GEM 1200 mg m(-2) on days 1, 8 and 15 every 28 days; PTX 100 mg m(-2) on days 1, 8 and 15 every 28 days; GEM 1000 mg m(-2) plus PTX 80 mg m(-2) (GT) on days 1 and 8 every 21 days; GEM 1000 mg m(-2) plus VNR 25 mg m(-2) (GV) on days 1 and 8 every 21 days. In all arms, an intra-patients dose escalation was applied over the first three courses, provided that no toxicity of WHO grade > or =2 had previously occurred. At present time, 217 (82%) patients had died. The median (months) and 1-year survival probability were 5.1 and 29% for GEM, 6.4 and 25% for PTX, 9.2 and 44% for GT, and 9.7 and 32% for GV. Multivariate analysis showed that PS< or =1 (hazard ratio (HR)=0.67; 95% CI 0.51-0.90), and doublet treatments (HR=0.76; 95% CI 0.59-0.99) were significantly associated with longer survival. Doublets produced no more toxicity than single agents. GT should be considered a reference regimen for elderly NSCLC patients with PS< or =1.

Project description:An increasing proportion of patients are exposed to anthracyclines and/or taxanes in the adjuvant or neoadjuvant setting. Re-exposure in the metastatic stage is limited by drug resistance, thus evaluation of non-cross-resistant regimens is mandatory.Anthracycline-pretreated patients were randomly assigned to three gemcitabine-based regimens. Chemotherapy consisted of gemcitabine 1.000?mg?m(-2) plus vinorelbin 25?mg?m(-2) on days 1+8 (GemVin), or plus cisplatin 30?mg?m(-2) on days 1+8 (GemCis), or plus capecitabine 650?mg?m(-2) b.i.d. orally days 1-14 (GemCap), q3w. The primary end point was response rate.A total of 141 patients were recruited on the trial. The overall response rates were 39.0% (GemVin), 47.7% (GemCis) and 34.7% (GemCap). Median progression-free survival was estimated with 5.7, 6.9 and 8.3 months, respectively. Corresponding median survival times were 17.5 (GemVin), 13.0 (GemCis) and 19.4 months (GemCap). Neutropenia ?grade 3 occurred in 16.7% (Gem/Vin), 4.4% (GemCis) and 0% (Gem/Cap), whereas non-haematological toxicities were rarely severe except grade 3 hand-foot syndrome in 2.0% of the GemCap patients (per patient analysis).This randomised phase II trial has revealed comparable results for three gemcitabine-based regimens regarding treatment efficacy and toxicity. Gemcitabine-based chemotherapy appears to be a worthwhile treatment option for pretreated patients with metastatic breast cancer.

Project description:Background: Lung cancers represent the main cause of cancer related-death in the world. Recently, immunotherapy alone or in combination with chemotherapies have deeply impacted the therapeutic care leading to an improved overall survival. However, relapse will finally occur, with no efficient second line treatments so far. The development of new therapies based on comprehension of mechanisms of resistance is necessary. However, the difficulties to obtain tumor samples before and after first line treatment hampers to clearly understand the consequence of these molecules on tumor cells and then, to identify adapted second line therapies. Methods: To overcome this difficulty, we developed multicellular tumor spheroids (MCTS) using characterized Non-Small Cell Lung Cancer (NSCLC) cell lines, monocytes from healthy donors and fibroblasts (Human Foreskin Fibroblasts-2, HFF2). MCTS were treated with carboplatin-paclitaxel or -gemcitabine combinations according to clinic schedule of administration consisting on three repetitions of treatments (one combination and two single treatments (paclitaxel or gemcitabine)). The impact of treatments was studied using cell viability assay, histology, 3’RNA sequencing, real-time PCR, flow cytometry and confocal microscopy. Results: We showed that treatments induced a decrease of cell viability and strong modifications in the transcriptomic profile notably at the level of pathways involved in DNA damages repair and the cell cycle. Interestingly, we also observed a modification of the expression of genes considered as hallmarks of response/resistance to immune check point inhibitors and immunogenicity and particularly an increase of CD274 gene expression, coding for PD-L1. This result was validated at the protein level and showed to be restricted to tumor cells on MCTS containing fibroblasts and macrophages. This increase was also observed on an additional cell line, expressing low basal level of CD274. These results are consistent with previous observations on patients showing higher PD-L1 tumoral expression after chemotherapy exposure. Conclusions: This study shows that MCTS could be interesting models to study the impact of first line therapies using conditions close to the clinical practice and then, to identify more adapted second line or concomitant therapies for the treatment of lung cancers.

Project description:BACKGROUND:A dose-dense weekly schedule of paclitaxel (resulting in a greater frequency of drug delivery) plus carboplatin every 3 weeks or the addition of bevacizumab to paclitaxel and carboplatin administered every 3 weeks has shown efficacy in ovarian cancer. We proposed to determine whether dose-dense weekly paclitaxel and carboplatin would prolong progression-free survival as compared with paclitaxel and carboplatin administered every 3 weeks among patients receiving and those not receiving bevacizumab. METHODS:We prospectively stratified patients according to whether they elected to receive bevacizumab and then randomly assigned them to receive either paclitaxel, administered intravenously at a dose of 175 mg per square meter of body-surface area every 3 weeks, plus carboplatin (dose equivalent to an area under the curve [AUC] of 6) for six cycles or paclitaxel, administered weekly at a dose of 80 mg per square meter, plus carboplatin (AUC, 6) for six cycles. The primary end point was progression-free survival. RESULTS:A total of 692 patients were enrolled, 84% of whom opted to receive bevacizumab. In the intention-to-treat analysis, weekly paclitaxel was not associated with longer progression-free survival than paclitaxel administered every 3 weeks (14.7 months and 14.0 months, respectively; hazard ratio for disease progression or death, 0.89; 95% confidence interval [CI], 0.74 to 1.06; P=0.18). Among patients who did not receive bevacizumab, weekly paclitaxel was associated with progression-free survival that was 3.9 months longer than that observed with paclitaxel administered every 3 weeks (14.2 vs. 10.3 months; hazard ratio, 0.62; 95% CI, 0.40 to 0.95; P=0.03). However, among patients who received bevacizumab, weekly paclitaxel did not significantly prolong progression-free survival, as compared with paclitaxel administered every 3 weeks (14.9 months and 14.7 months, respectively; hazard ratio, 0.99; 95% CI, 0.83 to 1.20; P=0.60). A test for interaction that assessed homogeneity of the treatment effect showed a significant difference between treatment with bevacizumab and without bevacizumab (P=0.047). Patients who received weekly paclitaxel had a higher rate of grade 3 or 4 anemia than did those who received paclitaxel every 3 weeks (36% vs. 16%), as well as a higher rate of grade 2 to 4 sensory neuropathy (26% vs. 18%); however, they had a lower rate of grade 3 or 4 neutropenia (72% vs. 83%). CONCLUSIONS:Overall, weekly paclitaxel, as compared with paclitaxel administered every 3 weeks, did not prolong progression-free survival among patients with ovarian cancer.

Project description:Background:Metastatic triple-negative breast cancer (mTNBC) has a poor prognosis and aggressive clinical course. tnAcity evaluated the efficacy and safety of first-line nab-paclitaxel plus carboplatin (nab-P/C), nab-paclitaxel plus gemcitabine (nab-P/G), and gemcitabine plus carboplatin (G/C) in patients with mTNBC. Patients and methods:Patients with pathologically confirmed mTNBC and no prior chemotherapy for metastatic BC received (1 : 1 : 1) nab-P 125?mg/m2 plus C AUC 2, nab-P 125?mg/m2 plus G 1000?mg/m2, or G 1000?mg/m2 plus C AUC 2, all on days 1, 8 q3w. Phase II primary end point: investigator-assessed progression-free survival (PFS); secondary end points included overall response rate (ORR), overall survival (OS), percentage of patients initiating cycle 6 with doublet therapy, and safety. Results:In total, 191 patients were enrolled (nab-P/C, n?=?64; nab-P/G, n?=?61; G/C, n?=?66). PFS was significantly longer with nab-P/C versus nab-P/G [median, 8.3 versus 5.5?months; hazard ratio (HR), 0.59 [95% CI, 0.38-0.92]; P?=?0.02] or G/C (median, 8.3 versus 6.0?months; HR, 0.58 [95% CI, 0.37-0.90]; P?=?0.02). OS was numerically longer with nab-P/C versus nab-P/G (median, 16.8 versus 12.1?months; HR, 0.73 [95% CI, 0.47-1.13]; P?=?0.16) or G/C (median, 16.8 versus 12.6?months; HR, 0.80 [95% CI, 0.52-1.22]; P?=?0.29). ORR was 73%, 39%, and 44%, respectively. In the nab-P/C, nab-P/G, and G/C groups, 64%, 56%, and 50% of patients initiated cycle 6 with a doublet. Grade ?3 adverse events were mainly hematologic. Conclusions:First-line nab-P/C was active in mTNBC and resulted in a significantly longer PFS and improved risk/benefit profile versus nab-P/G or G/C.

Project description:Objective:The objective of this open-label, randomized study was to compare dose-dense paclitaxel plus carboplatin (PCdd) with dose-dense epirubicin and cyclophosphamide followed by paclitaxel (ECdd-P) as an adjuvant chemotherapy for early triple-negative breast cancer (TNBC). Methods:We included Chinese patients with high recurrence risk TNBC who underwent primary breast cancer surgery. They were randomly assigned to receive PCdd [paclitaxel 150 mg/m2 on d 1 and carboplatin, the area under the curve, (AUC)=3 on d 2] or ECdd-P (epirubicin 80 mg/m2 divided in 2 d and cyclophosphamide 600 mg/m2 on d 1 for 4 cycles followed by paclitaxel 175 mg/m2 on d 1 for 4 cycles) every 2 weeks with granulocyte colony-stimulating factor (G-CSF) support. The primary endpoint was 3-year disease-free survival (DFS); the secondary endpoints were overall survival (OS) and safety. Results:The intent-to-treat population included 143 patients (70 in the PCdd arm and 73 in the ECdd-P arm). Compared with the ECdd-P arm, the PCdd arm had significantly higher 3-year DFS [93.9% vs. 79.1%; hazard ratio (HR)=0.310; 95% confidence interval (95% CI), 0.137-0.704; log-rank, P=0.005] and OS (98.5% vs. 92.9%; HR=0.142; 95% CI, 0.060-0.825; log-rank, P=0.028). Worse neutropenia (grade 3/4) was found in the ECdd-P than the PCdd arm (47.9% vs. 21.4%, P=0.001). Conclusions:PCdd was superior to ECdd-P as an adjuvant chemotherapy for early TNBC with respect to improving the 3-year DFS and OS. PCdd also yielded lower hematological toxicity. Thus, PCdd might be a preferred regimen for early TNBC patients with a high recurrence risk.

Project description:ObjectivePaclitaxel and carboplatin (PC) is a standard initial therapy for advanced endometrial cancer. We evaluated the efficacy and tolerability of incorporating three novel agents into initial therapy.MethodsIn this randomized phase II trial, patients with chemotherapy-naïve stage III/IVA (with measurable disease) and stage IVB or recurrent (with or without measurable disease) endometrial cancer were randomly assigned to treatment with PC plus bevacizumab (Arm 1), PC plus temsirolimus (Arm 2) or ixabepilone and carboplatin (IC) plus bevacizumab (Arm 3). The primary endpoint was progression-free survival (PFS). Comparable patients on the PC Arm of trial GOG209 were used as historical controls. Secondary endpoints were response rate, overall survival (OS), and safety.ResultsOverall, 349 patients were randomized. PFS duration was not significantly increased in any experimental arm compared with historical controls (p > 0.039). Treatment HRs (92% CI) for Arms 1, 2, and 3 relative to controls were 0.81 (0.63-1.02), 1.22 (0.96-1.55) and 0.87 (0.68-1.11), respectively. Response rates were similar across arms (60%, 55% and 53%, respectively). Relative to controls, OS duration (with censoring at 36 months), was significantly increased in Arm 1 (p < 0.039) but not in Arms 2 and 3; the HRs (92% CIs) were 0.71 (0.55-0.91), 0.99 (0.78-1.26), and 0.97 (0.77-1.23), respectively. No new safety signals were identified. Common mutations and rates of mismatch repair protein loss are described by histotype. Potential predictive biomarkers for temsirolimus and bevacizumab were identified.ConclusionPFS was not significantly increased in any experimental arm compared to historical controls.

Project description:BackgroundTriple-negative breast cancer is an aggressive disease with unmet clinical needs. In a phase III study of patients with metastatic triple-negative breast cancer, first-line gemcitabine/carboplatin resulted in a median progression-free survival of 4.6 months. nab-paclitaxel-based regimens (with gemcitabine or carboplatin±bevacizumab) also demonstrated efficacy and safety in first-line phase II trials of human epidermal growth factor receptor 2-negative metastatic breast cancer.Trial designIn this international, multicenter, open-label, randomized phase II/III trial, the efficacy and safety of first-line nab-paclitaxel with gemcitabine or with carboplatin will be compared with gemcitabine/carboplatin (control arm) for metastatic triple-negative breast cancer.MethodsIn the phase II portion, 240 patients with measurable metastatic triple-negative breast cancer and treatment-naive for metastatic disease will be randomized 1:1:1 (stratified by disease-free interval: ≤1 versus>1 year) to nab-paclitaxel 125 mg/m2 plus gemcitabine 1000 mg/m2, nab-paclitaxel 125 mg/m2 plus carboplatin area under the curve 2 mg×min/mL, or gemcitabine 1000 mg/m2 plus carboplatin area under the curve 2 mg×min/mL, all given on days 1 and 8 of a 21-day cycle. Investigator-assessed progression-free survival (primary endpoint), overall response rate, overall survival, and safety will be assessed. A ranking algorithm of five efficacy and safety parameters will be used to pick the "winner" of the nab-paclitaxel regimens. In the phase III portion, 550 patients will be randomized 1:1 (stratified by disease-free interval: ≤1 versus >1 year, and prior adjuvant/neoadjuvant taxane use) to the nab-paclitaxel combination arm selected from the phase II portion or to the control arm. Patients in phase II will not be part of the phase III population. The phase III primary endpoint is blinded, independently-assessed progression-free survival; secondary endpoints include blinded, independently-assessed overall response rate, overall survival, disease control rate, duration of response, and safety. Biomarker and circulating tumor-cell exploratory analyses and quality-of-life assessments will also be performed.

Project description:BackgroundThe continuum of anti-HER2 agents is a standard treatment of HER2 + metastatic breast cancer (MBC). This study evaluated the efficacy of lapatinib plus vinorelbine in patients progressed on both trastuzumab and lapatinib treatments.MethodsA total of 149 patients were randomly assigned to lapatinib with vinorelbine (LV) (n = 75; lapatinib, 1000 mg daily; vinorelbine 20 mg/m2 D1, D8 q3w) or vinorelbine (V) (n = 74; 30 mg/m2 D1, D8 q3w). The primary endpoint was progression-free survival (PFS) rate at 18 weeks.ResultsThe median number of previous anti-HER2 therapies was 2 (range 2-5). There was no significant difference in PFS rate at 18 weeks between LV and V arms (45.9% vs 38.9%, p = 0.40). ORR was 19.7% in LV arm, and 16.9% in V arm (p = 0.88). PFS and OS did not differ between two arms (LV vs V; median PFS, 16 vs 12 weeks, HR = 0.86, 95% CI 0.61-1.22; median OS, 15.0 vs 18.9 months, HR = 1.07, 95% CI 0.72-1.58). Toxicity profiles were similar in both arms and all were manageable.ConclusionsLapatinib plus vinorelbine treatment was tolerable; however, it failed to demonstrate the clinical benefits over vinorelbine alone in patients with HER2 + MBC after progression on both trastuzumab and lapatinib.Clinical trial registrationClinicalTrials.gov number NCT01730677.
