MINI17.07 - Efficacy of Nintedanib/Docetaxel after Bevacizumab, Pemetrexed or Taxanes Therapy (ID 1521)
17:25 - 17:30 | Author(s): M. Krzakowski
- Abstract
- Presentation
Background:
Nintedanib is a triple angiokinase inhibitor of receptors for vascular endothelial growth factor (VEGF), platelet-derived growth factor and fibroblast growth factor. The randomized, placebo-controlled, Phase III LUME-Lung 1 study (NCT00805194; 1199.13) investigating nintedanib/docetaxel was the first trial of an antiangiogenic agent to demonstrate significant overall survival (OS) benefit in previously treated patients with non-small cell lung cancer (NSCLC) of adenocarcinoma histology; nintedanib/docetaxel is approved in the European Union for the treatment of patients with locally advanced, metastatic or locally recurrent NSCLC of adenocarcinoma histology after 1[st]-line chemotherapy. Here we report LUME-Lung 1 data from the adenocarcinoma population who received 1[st]-line chemotherapy containing bevacizumab, pemetrexed or taxanes.
Methods:
In LUME-Lung 1, 1314 patients with Stage IIIB/IV recurrent NSCLC received either nintedanib/docetaxel or placebo/docetaxel. Primary endpoint was centrally assessed progression-free survival (PFS); OS was a key secondary endpoint. Prior treatment with anti-VEGF agent bevacizumab was a stratification factor. Analyses of the adenocarcinoma population (n=658) according to prior treatment with bevacizumab (n=45 in either arm), pemetrexed (1[st]-line [n=126] or maintenance [n=27]) or taxanes (n=142) were performed to determine if 1[st]-line regimens could influence subsequent outcomes for nintedanib/docetaxel.
Results:
Patient characteristics were generally well-balanced across prior-treatment subgroups. For the adenocarcinoma population, there was no interaction between 1[st]-line treatment with bevacizumab, pemetrexed or taxanes and treatment outcome with nintedanib/docetaxel. Independent of pretreatment, nintedanib/docetaxel-treated adenocarcinoma patients had an OS benefit (Table). In the overall patient population, efficacy outcomes for these subgroups were also similar regardless of prior treatment. Furthermore, there was no significant effect on nintedanib/docetaxel outcomes for the few adenocarcinoma patients who received maintenance pemetrexed. The adverse event (AE) profile for nintedanib/docetaxel in each subgroup was consistent with that reported for the adenocarcinoma population in LUME-Lung 1, with diarrhea and reversible liver enzyme elevations among the more frequently reported AEs. Among patients who received nintedanib/docetaxel, there was no difference between prior-treatment subgroups in the frequency of AEs commonly associated with the prior treatment, such as hypertension with bevacizumab, mucositis with pemetrexed and peripheral neuropathy with taxanes.
Conclusion:
In LUME-Lung 1, regardless of whether a patient with NSCLC of adenocarcinoma histology received 1[st]-line chemotherapy containing bevacizumab, pemetrexed or taxanes, subsequent treatment with nintedanib/docetaxel led to improved OS.Table: OS results in patients with NSCLC of adenocarcinoma tumor histology stratified by ± prior 1st-line bevacizumab, pemetrexed or taxanes treatment

P1.06-007 - Plasma Circulating MicroRNA-944 and MicroRNA-3662 as Novel Histologic Type-Specific Lung Cancer Biomarkers (ID 521)
09:30 - 09:30 | Author(s): M. Krzakowski
- Abstract
Background:
Altered expression of microRNAs is associated with development and invasion of cancers by regulating post-transcriptionally gene function. Possibility of detection of circulating miRNAs expression in patients’ plasma or serum make them valuable biomarkers of different neoplasms, such as lung cancer.
Methods:
We investigated potential role of miR-944 and miR-3662 expression analysis as a novel lung cancer biomarkers and their lung tumor specificity in plasma samples of 90 lung cancer patients (40 NSCLC patients in stage IA-IIIA and 20 NSCLC patients in stage IIIB-IV; 8 SCLC patients with limited and 22 SCLC patients with extensive disease) and 85 healthy individuals using qRT-PCR analysis.
Results:
Expression of miR-944 and miR-3662 was significantly upregulated in lung cancer patients in comparison to healthy individuals. Higher stage of lung cancer correlated with higher miRNAs expression (Figure 1). Receiver operating curves (ROC) analysis have presented diagnostic power of analysis of both miRNAs expression for detection of patients with I and II stage of NSCLC with area under curve (AUC) of 0.881. Moreover, miR-944 has shown diagnostic accuracy for operable squamous cell carcinoma detection (AUC=0.982) whereas miR-3662 - for operable adenocarcinoma (AUC=0.926) (Figure 2).Figure 1Figure 2
Conclusion:
Our research is a first study investigating the plasma expression of miR-944 and miR-3662 in patients with neoplasms and in healthy individuals. Moreover, this is a first study that described a miR-3662 expression. We have shown that examination of these two miRNAs may be considered as a tool for NSCLC early diagnosis as well as for non-invasive diagnosis of lung cancer late stages. Studied miRNAs have also shown high utility in detection of histological type-specific NSCLC subtypes, such as adenocarcinoma and squamous-cell carcinoma.
