Clinical Benefit from Docetaxel +/- Ramucirumab Is Not Associated with Mutation Status in Metastatic Non-Small-Cell Lung Cancer Patients Who Progressed on Platinum Doublets and Immunotherapy. Cancers (Basel) 2024; 16:935. [PMID: 38473297 PMCID: PMC10931294 DOI: 10.3390/cancers16050935] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 02/07/2024] [Accepted: 02/21/2024] [Indexed: 03/14/2024] Open
Abstract
Docetaxel +/- ramucirumab remains the standard-of-care therapy for patients with metastatic non-small-cell lung cancer (NSCLC) after progression on platinum doublets and immune checkpoint inhibitors (ICIs). The aim of our study was to investigate whether the cancer gene mutation status was associated with clinical benefits from docetaxel +/- ramucirumab. We also investigated whether platinum/taxane-based regimens offered a better clinical benefit in this patient population. A total of 454 patients were analyzed (docetaxel +/- ramucirumab n=381; platinum/taxane-based regimens n=73). Progression-free survival (PFS) and overall survival (OS) were compared among different subpopulations with different cancer gene mutations and between patients who received docetaxel +/- ramucirumab versus platinum/taxane-based regimens. Among patients who received docetaxel +/- ramucirumab, the top mutated cancer genes included TP53 (n=167), KRAS (n=127), EGFR (n=65), STK11 (n=32), ERBB2 (HER2) (n=26), etc. None of these cancer gene mutations or PD-L1 expression was associated with PFS or OS. Platinum/taxane-based regimens were associated with a significantly longer mQS (13.00 m, 95% Cl: 11.20-14.80 m versus 8.40 m, 95% Cl: 7.12-9.68 m, LogRank P=0.019) than docetaxel +/- ramcirumab. Key prognostic factors including age, histology, and performance status were not different between these two groups. In conclusion, in patients with metastatic NSCLC who have progressed on platinum doublets and ICIs, the clinical benefit from docetaxel +/- ramucirumab is not associated with the cancer gene mutation status. Platinum/taxane-based regimens may offer a superior clinical benefit over docetaxel +/- ramucirumab in this patient population.

Abstract
Background The genetic profiling of non-small cell lung cancer (NSCLC) has contributed to the discovery of actionable targetable mutations, which have significantly improved outcomes in disease with poor prognosis. Molecular epidemiological data of driver mutations in Indian populations have not been extensively elaborated compared to western and eastern Asian NSCLC populations. This study assessed the prevalence and clinical outcomes of EGFR (epidermal growth factor receptor) mutations among the Indian NSCLC cohort in South India. Patients and Methods Retrospective analysis of 2,003 NSCLC patients who had undergone EGFR mutational analysis from 2013 to 2020 was performed. Clinical analysis was performed for 141 patients from 2013 to 2017 using Kaplan-Meier and Chi-square methods. Descriptive and survival statistics were performed using IBM SPSS Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp. Results EGFR-sensitizing mutations were detected in 41.6% (834/2003) in the study cohort with compound mutations detected in 7.55% (63/834) of EGFR-positive cases. A significant relationship with regard to female gender and EGFR mutation status (P <.001) was observed. Exon 18 G719X (8.7%) mutations and exon 20 T790M point mutation (3.1%) were the most frequently isolated uncommon EGFR mutations. In the clinical cohort, EGFR mutations were detected at a significantly higher prevalence in females (P =0.002) and never-smokers (P < 0.001). EGFR mutation demonstrated a significant relationship with regard to brain metastasis (P = 0.011). EGFR mutated individuals had significantly longer median overall survival compared to EGFR wild type (26 months vs. 12 months, P = 0.044). Conclusion We reports the highest number of EGFR mutation analysis performed from India and mutational analysis indicated a loco-regional variation in India with regard to EGFR mutation frequency and its subtypes.

CANCER DIAGNOSIS & PROGNOSIS 2023; 3:215-220. [PMID: 36875305 PMCID: PMC9949548 DOI: 10.21873/cdp.10204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Accepted: 01/02/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND/AIM The antineoplastic drug docetaxel (DOC) and the antivascular endothelial growth factor inhibitor ramucirumab (RAM) are widely used in combination for second or later-line regimens for advanced non-small cell lung cancer (NSCLC). While the median progression-free survival (PFS) of DOC+RAM has been reported to be less than six months in both clinical trials and clinical practice, there appear to be some patients with long-term PFS. This study aimed to clarify the existence and characteristics of these patients. PATIENTS AND METHODS We conducted a retrospective review of patients with advanced NSCLC treated with DOC+RAM between April 2009 and June 2022 at our three hospitals. There was no established definition of long-term PFS, thus in this study, a PFS of 12 months or longer was defined as long-term PFS. RESULTS During the study period, 91 patients received DOC+RAM treatment. Of these, 14 (15.4%) achieved long-term PFS. There were no significant differences in patient characteristics between patients with PFS ≥12 months and those with PFS <12 months, except for 'clinical stage IIIA-C' at DOC+RAM initiation and 'post-surgical recurrence'. In uni- and multivariate analyses, favorable factors for PFS were 'Stage III at the start of DOC+RAM' in driver gene-negative patients, and 'under 70 years old' in driver gene-positive patients. CONCLUSION Many patients in this study achieved long-term PFS with DOC+RAM treatment. In the future, it is expected that long-term PFS will be defined, and the background of patients who achieve such PFS will become clearer.

Is the Efficacy of Adding Ramucirumab to Docetaxel Related to a History of Immune Checkpoint Inhibitors in the Real-World Clinical Practice? Cancers (Basel) 2022; 14:cancers14122970. [PMID: 35740634 PMCID: PMC9221111 DOI: 10.3390/cancers14122970] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 06/09/2022] [Accepted: 06/14/2022] [Indexed: 11/17/2022] Open
Abstract
Simple Summary Previous studies have shown that the use of chemotherapy in combination with immune checkpoint inhibitors as a first-line treatment in patients with non-small cell lung cancer improved overall survival and progression-free survival. However, the efficacy of cytotoxic agents as a second-line or later-line therapy in non-small cell lung cancer patients previously treated with immune checkpoint inhibitors in the real-world clinical practice is still controversial. In the present study, we retrospectively evaluated patients with non-small cell lung cancer to clarify whether the previous treatment with immune checkpoint inhibitors impacts the efficacy of docetaxel or the combined therapy of docetaxel plus ramucirumab. The results of this study using real-world data show that the addition of ramucirumab to docetaxel is superior to docetaxel monotherapy for improving time-to-treatment failure and overall survival, irrespective of previous treatment with immune checkpoint inhibitors. Abstract Reports on the efficacy of second-line treatment with cytotoxic agents after treatment with immune checkpoint inhibitors are limited. Here, we retrospectively evaluated patients in the real-world clinical practice treated with docetaxel or docetaxel plus ramucirumab. Ninety-three patients treated with docetaxel or docetaxel plus ramucirumab as a second- or later-line therapy were included. The patients were categorized into the following four treatment groups: docetaxel group (n = 50), docetaxel/ramucirumab group (n = 43) and pretreated (n = 45) and untreated (n = 48) with immune checkpoint inhibitor groups. The docetaxel/ramucirumab group showed an overall response rate of 57.1% in patients pretreated with immune checkpoint inhibitors and 20% in untreated patients. The docetaxel group showed an overall response rate of 15.4% in patients pretreated with immune checkpoint inhibitors and 5.0% in untreated patients. The median time-to-treatment failure and the median survival time were longer in the docetaxel/ramucirumab group than in the docetaxel group in both immune checkpoint inhibitor-pretreated and -untreated groups. There was no difference in time-to-treatment failure and overall survival between immune checkpoint inhibitor-pretreated and -untreated groups in each docetaxel and docetaxel/ramucirumab treatment group. In conclusion, our real-world data show that the addition of ramucirumab to docetaxel was superior to docetaxel monotherapy for improving time-to-treatment failure and overall survival, irrespective of previous treatment with immune checkpoint inhibitors.

Abstract
Background Ramucirumab paired with docetaxel extends progression free survival and overall survival in non-small cell lung cancer (NSCLC) following progression on platinum therapy. There is some data that epidermal growth factor receptor (EGFR) mutant disease would respond better to vascular endothelial growth factor receptor (VEGFR) therapy than EGFR wild type disease. Methods This retrospective, single-institution cohort study reports outcomes of patients who received docetaxel with or without ramucirumab according to EGFR status. Clinical data including age, performance status, metastatic burden and prior treatment history was obtained and reported with time on treatment and overall survival as primary endpoints. Data analysis was performed for three cohorts: EGFR mutant disease receiving docetaxel and ramucirumab (EGFR-doce/ram), EGFR mutant disease receiving docetaxel alone (EGFR-doce) and EGFR wild type disease receiving docetaxel and ramucirumab (WT-doce/ram). Results Patients in the EGFR-doce/ram cohort had a median time on docetaxel of 1.4 months (95% CI: 0.72-5.2 months) and of 0.8 months (95% CI: 0.2-6.5 months) on ramucirumab. Patients in the EGFR-doce cohort were on docetaxel for a median 1.4 months (95% CI: 0.9-2.4 months). Patients in the WT-doce/ram cohort had a median time on docetaxel of 2.3 months (95% CI: 1.6-4.1 months) and on ramucirumab of 1.4 months (95% CI: 0.8-3.2 months). There was no significant difference between time on ramucirumab or docetaxel between the cohorts. Overall survival for the three cohorts was noted to be 6.7 months (95% CI: 2.5-16.2 months) for the EGFR-doce/ram cohort, 4.9 months (95% CI: 4.2-12.5 months) for the EGFR-doce cohort and 6.6 months (95% CI: 4.3-12.8 months) for the WT-doce/ram cohort. There was no significant difference in overall survival between the cohorts. Conclusions Our data did not support the initial hypothesis that patients with EGFR mutant disease would do better with the addition of ramucirumab. Our study was limited by small sample size, retrospective nature and inability to control for confounders including prior bevacizumab or immune checkpoint inhibitor (ICI) exposure. This study offers real-world estimates to clinicians and patients about the length of time they can expect to derive benefit from the combination of ramucirumab and docetaxel.

Abstract
Background T790M mutation causes resistance to tyrosine kinase inhibitors (TKIs) in approximately 49% of patients with epidermal growth receptor‐mutant non‐small cell lung cancer (NSCLC). The cause of resistance in the remaining half of the cases is a minor mutation or unknown. Here, we conducted a retrospective study of epidermal growth receptor‐mutant NSCLC patients with T790M‐negative or an unidentified mutation to appraise the therapeutic response to first‐ or second‐generation tyrosine kinase inhibitors as a second‐line treatment. Methods The study included 39 patients treated in our institution from April 2012 through March 2020 with second‐line tyrosine kinase inhibitors or chemotherapy after completing a first‐line therapy with tyrosine kinase inhibitors. Results The patients were allocated to two groups: chemotherapy (n = 28) and a tyrosine kinase inhibitor (n = 11) groups. The median progression‐free survival (PFS) was 5.4 months in the chemotherapy group and 3.4 months in the tyrosine kinase inhibitor group (p‐value = 0.36), while the median overall survival (OS) was 16.1 months in the chemotherapy group and 12.8 months in the tyrosine kinase inhibitor group (p‐ value = 0.20). This study showed no significant difference in PFS and OS between the chemotherapy and tyrosine kinase inhibitor groups. Conclusions These observations suggest that first‐ and second‐generation tyrosine kinase inhibitors are not recommended for second‐line treatment in epidermal growth factor receptor‐mutated NSCLC patients with T790M‐negative mutation who have received tyrosine kinase inhibitors as first‐line treatment.
