Nab-paclitaxel is a novel therapeutic agent, which was approved in combination with carboplatin in the first-line treatment of advanced non-small cell lung cancer (NSCLC) regardless of histologic subtype in the United States of America by the Food and Drug Administration in 2012 and by the European Commission in 2015. This approval was based on the results of a phase III clinical trial showing superior response rates compared with solvent-based paclitaxel in combination with carboplatin. This re ...[more]

Project description:IntroductionDespite improvements in the treatment of advanced non-small cell lung cancer (NSCLC), certain patient populations remain underrepresented in clinical trials. Many patients have benefited from platinum doublets, including nab-paclitaxel-based regimens, but there are patients with comorbidities who particularly require careful balancing of efficacy and safety. Clinical trial data are limited for patients who are elderly or have renal impairment, diabetes, or impaired performance status.MethodsTo better understand outcomes in these patient populations, we performed a pooled analysis using data from the ABOUND clinical trial program (ABOUND.SQM, ABOUND.PS2, ABOUND.70+) and the key phase III trial of nab-paclitaxel/carboplatin in advanced NSCLC. The populations included in this pooled analysis consisted of elderly patients (≥ 70 years) and patients with renal impairment (eGFR < 60 ml/min/1.73 m2), diabetes, or poor performance status (ECOG PS 2).ResultsMedian progression-free survival (PFS) ranged from 4.1 months in patients with ECOG PS 2 (95% CI, 2.04-5.09 months) to 7.7 months in patients with diabetes (95% CI, 5.88-10.12 months). PFS for elderly patients and patients with renal impairment was 6.9 months each (95% CI, 6.01-7.98 months and 4.47-9.79 months, respectively). Median overall survival (OS) was 18.2 months (95% CI, 10.94-28.22 months), 17.4 months (95% CI, 14.59-20.14 months), and 16.1 months (95% CI, 14.09-18.50 months) in patients with renal impairment, patients with diabetes, and elderly patients, respectively. Patients with ECOG PS 2 exhibited the shortest median OS: 5.6 months (95% CI, 3.98-11.37 months). Overall response rates were 56.9%, 54.6%, 45.9%, and 29.4% in patients with diabetes, elderly patients, patients with renal impairment, and patients with ECOG PS 2, respectively. Most treatment-related adverse events were hematologic. The most common grade 3/4 hematologic adverse events in patients with renal impairment, elderly patients, patients with diabetes, and patients with poor performance status included neutropenia, anemia, and thrombocytopenia.ConclusionsAlthough survival data in patients with ECOG PS 2 were notably inferior to the other cohorts, our findings are consistent with those previously reported in the population-specific studies of the ABOUND trials and lend additional support for the use of nab-paclitaxel-based regimens in historically understudied and vulnerable populations.

Project description:BackgroundInduction with four cycles of platinum-based chemotherapy was the standard of care for metastatic non-small cell lung cancer (NSCLC) until the approval of immune checkpoint blockade (ICB) in the first-line setting. Switch maintenance therapy has shown promise in improving survival by exposing patients to novel, non-cross-resistant agents earlier in their treatment course.MethodsWe performed this open-label, three-arm, randomized phase II study (NCT02684461) to evaluate three sequences of consolidation with pembrolizumab and nab-paclitaxel in patients without progressive disease post induction chemotherapy. Consolidation was either sequential with pembrolizumab for four cycles followed by nab-paclitaxel for four cycles (P→A), nab-paclitaxel followed by pembrolizumab (A→P), or concurrent nab-paclitaxel and pembrolizumab for four cycles (AP).ResultsTwenty patients were randomized before the study was closed early due to the approval of first-line checkpoint inhibitors. We found that consolidation is feasible and well tolerated, with 30% of patients experiencing grade 3 toxicity. The median progression-free survival and OS in months (95% CI) in P→A were 10.1 (1.5-NR), 27.6 (1.7-NR); 8.4 (1.2-9.0), 12.7 (4.4-NR) in A→P; and 10.2 (5.1-NR), NR. Quality of life as measured by FACT-L improved in the majority of patients during the course of the study.ConclusionSequential and concurrent consolidation regimens are well tolerated and have encouraging overall survival in patients with metastatic NSCLC.

Project description:Background: The standard therapy for advanced stage non-small cell lung cancer (NSCLC) with no actionable gene alterations is a platinum-based chemotherapy doublet and immune checkpoint blocker (ICB), either concurrently or sequentially, followed by docetaxel at the time of tumor progression. However, more effective treatments are needed. We evaluated the nab-paclitaxel and durvalumab combination in patients with previously treated advanced stage NSCLC. Methods: Patients with advanced stage NSCLC previously treated with one line of platinum-based doublet with or without an ICB and no activating EGFR mutations or ALK translocations received nab-paclitaxel 100 mg/m2 (days 1 and 8) plus durvalumab 1,125 mg (day 15) every 21 days. The primary endpoint was progression-free survival (PFS). Key secondary endpoints included overall survival (OS) and safety. Results: Between February 2016 and December 2016, 79 patients were enrolled. The median age was 63 years. Most patients were males (68.4%), had non-squamous histology (69.6%), and had no prior ICB treatment (88.6%). The median PFS was 4.5 months; median OS was 10.1 months. A post hoc analysis of survival by prior ICB treatment revealed a median PFS and OS of 4.4 and 9.9 months, respectively, in ICB-naive patients and 6.9 months and not estimable, respectively, in patients previously treated with ICB. The most common treatment-emergent adverse events were asthenia (46.2%) and diarrhea (34.6%); four treatment-related deaths (5.1%) occurred. Conclusions: The nab-paclitaxel and durvalumab combination is feasible and demonstrated antitumor activity without new safety signals. Additional studies using taxanes and ICB in patients with previously treated NSCLC are warranted. Clinical Trial Registration: ClinicalTrials.gov registration (NCT02250326). EudraCT number: 2014-001105-41.

Project description:BackgroundPlatinum-based chemotherapy remains a first-line standard of care for approximately 30% of patients with non-small cell lung cancer (NSCLC) not harboring a druggable alteration. Favorable efficacy and safety of the nab-paclitaxel/carboplatin (nab-P/C) combination was shown in the pivotal phase 3 trial. However, information on effectiveness of nab-P/C in a real-world setting in Germany is missing. The NEPTUN study prospectively investigated the effectiveness and safety of nab-P/C in patients with advanced NSCLC in a real-world setting.MethodsPatients with advanced or metastatic NSCLC received first-line nab-P/C according to clinical routine. The primary endpoint was 6-month progression-free survival rate (PFS6). Other endpoints included further effectiveness parameters, safety and quality of life. Data were analyzed descriptively.Results408 patients were enrolled. PFS6 was 40.8% (95% confidence interval [CI], 35.3-46.2); median PFS was 5.2 months (95% CI, 4.5-5.7). overall response rate was 41.5% (95% CI, 36.3-46.8). Median overall survival (OS) was 10.5 months (95% CI, 9.2-11.6). Subgroup analyses revealed median OS for squamous versus non-squamous histology (11.8 months [95% CI, 9.2-13.8] vs. 9.6 months [95% CI, 7.7-11.2]) and age ≥70 versus <70 years (11.7 months [95% CI, 9.4-14.3] vs. 9.6 months [95% CI, 7.5-11.2]). Most common treatment-emergent adverse events (TEAEs) were anemia (26.5%), leukopenia (25.7%), and thrombocytopenia (16.6%). Mostly reported grade 3/4 TEAEs were leukopenia (10.2%), anemia (8.6%), and pneumonia (5.1%). nab-paclitaxel-related deaths as reported by the investigator occurred in 0.8% of patients.ConclusionThese real-world data support the effectiveness and safety of nab-P/C as first-line treatment for patients with advanced NSCLC independent of tumor histology. The results are comparable with the pivotal phase 3 trial. No new safety signals emerged.

Project description:BACKGROUND:Previous trials have suggested that elderly patients with non-small-cell lung cancer (NSCLC) could benefit from nanoparticle albumin-bound paclitaxel (nab-paclitaxel). Real-world data on the elderly Chinese population are lacking. This study aimed to analyze the effectiveness and tolerability of nab-paclitaxel in Chinese elderly patients (?65?years) with advanced NSCLC. METHODS:This study included 76 patients with a primary diagnosis of IIIB-IV NSCLC from January 2010 to December 2017 at Peking University Cancer Hospital, who received nab-paclitaxel (125 or 130?mg/m2 i.v.) every three?weeks. The overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and adverse events (AEs) were analyzed. RESULTS:There were 12 patients who received nab-paclitaxel as the first-line treatment (seven also received carboplatin), and 64 received nab-paclitaxel as the latter-line treatment. The overall ORR, DCR, median PFS, and median OS were 14.5%, 69.7%, 5.2?months, and 12.2?months, respectively. The Eastern Cooperative Oncology Group performance status of one and the age of 70-74?years were independently associated with longer OS, while early treatment line of nab-paclitaxel and age of 70-74?years were independently associated with longer PFS. The most common AEs were anemia, leukopenia, gastrointestinal reaction, fatigue, and peripheral neuropathy, which were all manageable. Dose adjustment or treatment discontinuation was encountered in 10 patients because of AEs. The incidence of AEs was not different among age subgroups. CONCLUSIONS:Nab-paclitaxel has a good clinical response profile in Chinese elderly patients with stage IIIB-IV NSCLC. Prospective clinical trials are needed to confirm these results. KEY POINTS:Significant findings of the study Nanoparticle albumin-bound paclitaxel (nab-paclitaxel) has a good clinical response profile in Chinese elderly (?65?years) patients with stage IIIB-IV non-small-cell lung cancer (NSCLC), with acceptable and manageable adverse events. What this study adds Preliminary evidence shows a good clinical response from treatment with nab-paclitaxel in Chinese elderly patients with advanced NSCLC.

Project description:Background:Limited data on elderly patients with squamous advanced non-small cell lung cancer (NSCLC) preclude optimal treatment. Here, we report the outcomes of a retrospective analysis of a subset of patients ?70 years with squamous histology from the Phase III trial that evaluated nab-paclitaxel/carboplatin vs paclitaxel/carboplatin. Patients and methods:Patients with stage IIIB/IV NSCLC received (1:1) nab-paclitaxel 100 mg/m2 on days 1, 8, and 15 or paclitaxel 200 mg/m2 on day 1, both with carboplatin area under the curve 6 mg×min/mL on day 1 every 3 weeks. The primary endpoint was independently assessed overall response rate as per the Response Evaluation Criteria in Solid Tumors v1.0. Secondary endpoints included progression-free survival, overall survival, and safety. Results:Sixty-five patients ?70 years with squamous histology were included (nab-paclitaxel/carboplatin, n=35; paclitaxel/carboplatin, n=30). nab-Paclitaxel/carboplatin vs paclitaxel/carboplatin, respectively, resulted in an overall response rate of 46% vs 20% (response rate ratio, 2.29, P=0.029) and a median overall survival of 16.9 vs 8.6 months (hazard ratio, 0.50, P=0.018). No difference was observed in median progression-free survival (5.7 months for both). Incidences of grade 3/4 neutropenia (50% vs 63%), leukopenia (29% vs 37%), fatigue (3% vs 13%), and peripheral neuropathy (3% vs 13%) were lower, but those of thrombocytopenia (21% vs 10%) and anemia (21% vs 7%) were higher with nab-paclitaxel/carboplatin vs paclitaxel/carboplatin. Conclusion:nab-Paclitaxel/carboplatin was efficacious and tolerable in patients ?70 years with squamous NSCLC. These results build upon prior analyses, indicating that nab-paclitaxel/carboplatin is effective for this difficult-to-treat patient subgroup.

Project description:The concomitant use of weekly nab-paclitaxel and carboplatin with concurrent radiotherapy was demonstrated to be a safe therapeutic approach in this phase I trial of 10 evaluable patients with stage III NSCLC.Despite the lack of systemic glucocorticoids, there were no reported infusion reactions or cases of peripheral neuropathy in this trial, both of which are known to occur with the use of paclitaxel.Unresectable stage III non-small cell lung cancer (NSCLC) has a 5-year survival rate of 20%, and concurrent chemoradiotherapy results in significant toxicity with the use of current chemotherapeutic agents. nab-Paclitaxel was approved by the U.S. Food and Drug Administration in October 2012 for use along with carboplatin in advanced NSCLC. This study was undertaken to determine the maximum tolerated dose and dose-limiting toxicities (DLTs) of weekly nab-paclitaxel given in combination with carboplatin and concurrent radiotherapy in patients with unresectable stage III NSCLC.Escalating doses of once-weekly nab-paclitaxel were given along with once-weekly carboplatin area under the plasma concentration time curve (AUC) of 2 and concurrent radiotherapy 66 Gy in 33 fractions, followed by 2 cycles of carboplatin and nab-paclitaxel consolidation chemotherapy.Eleven patients were enrolled and received treatment per protocol, with 10 evaluable for efficacy and toxicity. At dose level 1 (nab-paclitaxel 60 mg/m(2)), 2 DLTs were observed: esophagitis and radiation dermatitis. Six patients were enrolled at dose level 0 (nab-paclitaxel 40 mg/m(2)) with no DLTs. Nine of 10 evaluable patients had a partial response.Concurrent chemoradiotherapy with nab-paclitaxel 40 mg/m(2) and carboplatin AUC 2 is a safe and well-tolerated therapeutic regimen in patients with stage III NSCLC. A separate phase I/II study to evaluate the efficacy of this regimen is under way.

Project description:Paclitaxel-based chemotherapy is widely used as the first-line treatment for non-small cell lung cancer (NSCLC). However, only 20%-40% of patients have shown sensitivity to paclitaxel. This study aimed to investigate whether P16 methylation could be used to predict paclitaxel chemosensitivity of NSCLC. Advanced NSCLC (N=45) were obtained from patients who were enrolled in a phase-III randomized paclitaxel-based clinical trial. Genomic DNA samples were extracted from the biopsies prior to chemotherapy. P16 methylation was detected using MethyLight. The association between P16 methylation and the sensitivity of paclitaxel in cell lines was determined by in vitro assay using a P16-specific DNA demethylase (P16-TET) and methyltransferase (P16-Dnmt). The total response rate of the low-dose paclitaxel-based chemo-radiotherapy was significantly lower in P16 methylation-positive NSCLCs than that in the P16 methylation-negative NSCLCs (2/15 vs. 16/30: adjusted OR=0.085; 95%CI, 0.012-0.579). Results revealed that P16 demethylation significantly decreased paclitaxel resistance of lung cancer H1299 cells (IC50 values decreased from 2.15 to 1.13 µg/ml, P<0.001). In contrast, P16-specific methylation by P16-Dnmt significantly increased paclitaxel resistance of lung cancer HCC827 cells and gastric cancer BGC823 cells (IC50 values increased from 18.2 to 24.0 ng/ml and 0.18 to 0.81 µg/ml, respectively; P=0.049 and <0.001, respectively). The present results suggest that P16 methylation may lead to paclitaxel resistance and be a predictor of paclitaxel chemosensitivity of NSCLC.

Project description:OBJECTIVES:Chemotherapy remains a cornerstone treatment in non-small cell lung cancer either in combination with checkpoint inhibitors or as subsequent therapy. Identifying molecular predictors of response allows for optimal treatment selection. We performed genomic analysis on tumor samples of patients treated with carboplatin and nab-paclitaxel as part of a phase II trial to evaluate the prognostic and predictive value of mutations in DNA repair pathway in patients treated with this regimen. MATERIALS AND METHODS:Next-generation sequencing libraries were produced using a capture-based targeted panel covering the coding exons of 278 genes on patients treated on clinical trial NCT00729612. Overall survival (OS) and progression-free survival (PFS) were assessed as part of the clinical outcomes and correlated with mutation analysis. RESULTS:Of 63 patients enrolled, 25 patients had sufficient and acceptable DNA isolated from archival tumor samples for targeted sequencing. The most commonly altered pathways included DNA repair (DR) including Fanconi anemia and homologous recombination, JAK-STAT signaling, IGF-1, mTOR, and MAPK-ERK. Four patients with mutations in homologous recombination mutations had a shorter PFS (hazard ratio [HR]?=?4.54, 95% CI 1.2, 17.1, p?=?0.026) and OS (HR?=?6.3, 95% CI 1.8, 21.3, p?=?0.003). CONCLUSION:In this analysis of patients with predominantly squamous cell non-small cell lung cancer treated with carboplatin and nab-paclitaxel in a phase II trial, patients with mutations in homologous recombination pathways had shorter overall and progression-free survival. Validation on additional datasets of patients treated with platinum-based chemotherapy and immunotherapy combinations is warranted.

Project description:Lung cancer is the leading cause of cancer mortality worldwide in both men and women. Non-small-cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for more than 80% of cases. Paclitaxel has a broad spectrum of activity against various malignancies, including NSCLC. Paclitaxel is poorly soluble in water and thus, until recently, its commercially available preparations contained a non-ionic solvent Cremophor EL®. Cremophor EL® improves the solubility of paclitaxel and allows its intravenous administration. However, certain side-effects associated with paclitaxel, such as hypersensitivity reactions, myelosuppression, and peripheral neuropathy, are known to be worsened by Cremophor®. Nanoparticle albumin-bound paclitaxel ([nab-paclitaxel] ABRAXANE® ABI-007) is a new generation formulation of paclitaxel that obviates the need for Cremophor®, resulting in a safer and faster infusion without requiring the use of premedications to avoid hypersensitivity. Albumin-binding receptor-mediated delivery and lack of sequestering Cremophor® micelles allow higher intratumoral concentration of pharmacologically active paclitaxel. Multiple clinical trials have demonstrated a superior tolerability profile of nab-paclitaxel in comparison to solvent-bound paclitaxel (sb-paclitaxel). A recent Phase III trial compared the effects of weekly nab-paclitaxel in combination with carboplatin versus sb-paclitaxel in combination with carboplatin given every 3 weeks for first line treatment of NSCLC. This trial highlights the weekly nab-paclitaxel combination as an alternate treatment option for NSCLC, with higher response rate in squamous cell NSCLC and longer survival in elderly patients. This review will focus on the properties of nab-paclitaxel and its use in the first line treatment of NSCLC.
