Ohno H, Hayashi T, Torii S, Niwa M, Katagiri N, Nakao Y, Mano S, Takimoto N, Hirashita T. Influence of Previous Therapy for Neutropenia Caused by Combination Therapy of Ramucirumab and Docetaxel. Cancers (Basel) 2024; 16:2076. [PMID: 38893195 PMCID: PMC11171386 DOI: 10.3390/cancers16112076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2024] [Revised: 05/27/2024] [Accepted: 05/28/2024] [Indexed: 06/21/2024] Open
Abstract
In the present study, the influence of previous immune checkpoint inhibitor (ICI) therapy with ramucirumab (RAM) + docetaxel (DTX) therapy on the occurrence of severe neutropenia in patients with non-small cell lung cancer (NSCLC) was evaluated, taking into account the influences of cytotoxic chemotherapy used in pretreatment. The study participants included patients who received a combination therapy of RAM and DTX as cancer chemotherapy for NSCLC. The influences of previous ICI treatment and pretreatment with cytotoxic anticancer agents on the development of grade ≥ 3 neutropenia were analysed. A total of 89 patients, including 50 with and 39 without a history of ICI treatment, were analysed. Kaplan-Meier curves showed a significant difference in the influence of previous ICI treatment on the development of grade ≥ 3 neutropenia (p = 0.006). Moreover, Cox regression analysis identified a history of ICI treatment and prophylactic administration of G-CSF as factors associated with the development of grade ≥ 3 neutropenia (p = 0.018 and p < 0.001, respectively). This study found that previous treatment with ICIs reduced the incidence of grade ≥ 3 neutropenia after RAM + DTX therapy in patients with NSCLC, regardless of the influences of pretreatment with cytotoxic anticancer agents.

International Cost-Effectiveness Analysis of Durvalumab in Stage III Non-Small Cell Lung Cancer. JAMA Netw Open 2024; 7:e2413938. [PMID: 38814640 PMCID: PMC11140532 DOI: 10.1001/jamanetworkopen.2024.13938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Accepted: 03/28/2024] [Indexed: 05/31/2024] Open
Abstract
Importance Standard of care for unresectable locally advanced non-small cell lung cancer (NSCLC) involves definitive chemoradiotherapy followed by maintenance therapy with durvalumab. However, the cost of durvalumab has been cited as a barrier to its use in various health systems. Objective To evaluate the cost-effectiveness of durvalumab vs placebo as maintenance therapy in patients with unresectable stage III NSCLC from 4 international payer perspectives (US, Brazil, Singapore, and Spain). Design, Setting, and Participants In this economic evaluation, a Markov model was designed to compare the lifetime cost-effectiveness of maintenance durvalumab for unresectable stage III NSCLC with that of placebo, using 5-year outcomes data from the PACIFIC randomized placebo-controlled trial. Individual patient data were extracted from the PACIFIC, KEYNOTE-189, ADAURA, ALEX, and REVEL randomized clinical trials to develop a decision-analytic model to determine the cost-effectiveness of durvalumab compared with placebo maintenance therapy over a 10-year time horizon. Direct costs, adverse events, and patient characteristics were based on country-specific payer perspectives and demographic characteristics. The study was conducted from June 1, 2022, through December 27, 2023. Main Outcomes and Measures Life-years, quality-adjusted life years (QALYs), lifetime costs, and incremental cost-effectiveness ratios (ICERs) were estimated at country-specific willingness-to-pay thresholds ([data reported in US$] US: $150 000 per QALY; Brazil: $22 251 per QALY; Singapore: $55 288 per QALY, and Spain: $107 069 per QALY). One-way and probabilistic sensitivity analyses were performed to account for parameters of uncertainty. A cost-threshold analysis was also performed. Results The US base-case model found that treatment with durvalumab was associated with an increased cost of $114 394 and improved effectiveness of 0.50 QALYs compared with placebo, leading to an ICER of $228 788 per QALY. Incremental cost-effectiveness ratios, according to base-case models, were $141 146 for Brazil, $153 461 for Singapore, and $125 193 for Spain. Durvalumab price adjustments to the PACIFIC data improved cost-effectiveness in Singapore, with an ICER of $45 164. The model was most sensitive to the utility of durvalumab. Conclusions and Relevance In this cost-effectiveness analysis of durvalumab as maintenance therapy for unresectable stage III NSCLC, the therapy was found to be cost-prohibitive from the perspective of various international payers according to country-specific willingness-to-pay thresholds per QALY. The findings of the study suggest that discounted durvalumab acquisition costs, as possible in Singapore, might improve cost-effectiveness globally.

Abstract
BACKGROUND The factors that predict the clinical response to ramucirumab plus docetaxel (RD) after first-line chemoimmunotherapy are unresolved. We explored whether the therapeutic efficacy of prior chemoimmunotherapy could predict the outcome of RD as sequential therapy in patients with advanced non-small cell lung cancer (NSCLC). METHODS Our study comprised 288 patients with advanced NSCLC who received RD as the second-line treatment after first-line chemoimmunotherapy at 62 Japanese institutions. Chemoimmunotherapy consisted of a platinum-based regimen and immune checkpoint inhibitors (ICIs). The association between several variables and the therapeutic outcome of RD was determined via logistic regression analysis. RESULTS Of the 288 patients, 225 (78.1%) received maintenance therapy and 108 (37.5%) received both ICI treatment for >180 days and maintenance therapy. All of 108 patients having ICIs for >180 days received maintenance therapy. Univariate analysis identified performance status, histology (adenocarcinoma), maintenance therapy, and ICI treatment >180 days as significant predictors of better progression-free survival (PFS) and overall survival (OS) after RD administration. Multivariate analysis confirmed that these factors independently predicted favorable PFS and OS. The therapeutic response and PD-L1 expression were not closely associated with outcome after RD treatment. In particular, maintenance therapy >4 cycles was more predictive of the better prognosis for RD treatment. CONCLUSION Extended ICI treatment after chemoimmunotherapy and maintenance therapy enhanced the efficacy of second-line RD treatment in patients with advanced NSCLC.

Abstract
Lung cancer, as a malignant tumor with both high incidence and mortality in China, is one of the major causes of death in our population and one of the major public health problems in China. Effective treatment of lung cancer is a major public health task for all human beings. Angiogenesis plays an important role in the development of tumor, not only as a basic condition for tumor growth, but also as a significant factor to promote tumor metastasis. Therefore, anti-angiogenesis has become a vital means to inhibit tumor development, and anti-angiogenic drugs can rebalance pro- and anti-angiogenic factors to inhibit tumor cells. This article reviews the mechanism of blood vessel formation in tumor tissues and the mechanism of action of different anti-angiogenic drugs, the combination therapy of anti-angiogenic drugs and other anti-tumor drugs, and the mechanism of anti-angiogenic drug resistance.

Clinical outcomes of ramucirumab plus docetaxel in the treatment of patients with non-small cell lung cancer after immunotherapy: a systematic literature review. Front Oncol 2023; 13:1247879. [PMID: 37731641 PMCID: PMC10507469 DOI: 10.3389/fonc.2023.1247879] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 08/10/2023] [Indexed: 09/22/2023] Open
Abstract
Introduction In the REVEL trial, ramucirumab plus docetaxel demonstrated significant improvements in overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) compared with placebo plus docetaxel for treatment of metastatic non-small cell lung cancer (NSCLC) that progressed during or after platinum-based chemotherapy. Since the approval of ramucirumab plus docetaxel, immune checkpoint inhibitors (ICIs), either as single agents or in combination with chemotherapy, have become the standard of care for first-line treatment of patients with advanced NSCLC. However, efficacy and safety data for ramucirumab plus docetaxel after prior ICI treatment from randomized controlled clinical studies are lacking. Methods Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic literature review was performed. Electronic databases and select international oncology conference proceedings were searched. Studies published between 01 January 2014 and 01 July 2022, which evaluated 2 efficacy outcomes (and included at least 1 time-to-event endpoint) or safety outcomes of ramucirumab plus docetaxel in NSCLC that progressed after prior ICI treatment, were identified. Twelve studies were included in the analysis. Two treatment groups were selected: ramucirumab plus docetaxel after prior ICI ± chemotherapy (RAM + DTX ICI pre-treated) and ramucirumab plus docetaxel after prior chemotherapy only (RAM + DTX ICI naïve). OS, PFS, ORR, disease control rate (DCR), and safety data were extracted and descriptively summarized across both treatment groups. Results The pooled weighted median PFS and median OS were 5.7 months (95% confidence interval [CI]: 3.9-6.8) and 11.2 months (95% CI: 7.5-17.5), respectively, in the RAM + DTX ICI pre-treated group and 3.8 months (95% CI: 2.3-4.1) and 13.5 months (95% CI: 8-24.0), respectively, in the RAM + DTX ICI naïve group. The ORR and DCR ranged from 20.9% to 60.0% and from 62.4% to 90.0%, respectively, in the RAM + DTX ICI pre-treated group and from 17.7% to 20.0% and from 57.1% to 75.0%, respectively, in the RAM + DTX ICI naïve group. The safety profile across studies was consistent between both treatment groups, and no new safety signals were reported. Conclusions Cumulatively, these results support the combination of ramucirumab plus docetaxel as an effective and safe subsequent therapy for the treatment of patients with metastatic NSCLC with disease progression irrespective of previous ICI treatment.

Abstract
While new targeted therapies have considerably changed the treatment and prognosis of non-small cell lung cancer (NSCLC), they are frequently unsuccessful due to primary or acquired resistances. Chemoresistance is a complex process that combines cancer cell intrinsic mechanisms including molecular and genetic abnormalities, aberrant interactions within the tumor microenvironment, and the pharmacokinetic characteristics of each molecule. From a pharmacological point of view, two levers could improve the response to treatment: (i) developing tools to predict the response to chemo- and targeted therapies and (ii) gaining a better understanding of the influence of the tumor microenvironment. Both personalized medicine approaches require the identification of relevant experimental models and biomarkers to understand and fight against chemoresistance mechanisms. After describing the main therapies in NSCLC, the scope of this review will be to identify and to discuss relevant in vitro and ex vivo experimental models that are able to mimic tumors. In addition, the interests of these models in the predictive responses to proposed therapies will be discussed. Finally, this review will evaluate the involvement of novel secreted biomarkers such as tumor DNA or micro RNA in predicting responses to anti-tumor therapies.

Abstract
BACKGROUND This study evaluated the safety and effectiveness of ramucirumab and docetaxel for non-small cell lung cancer (NSCLC) in real-world settings. RESEARCH DESIGN AND METHODS This single-arm, prospective, multicenter, non-interventional, post-marketing study was conducted in Japan between August 2016 and January 2020. Patients diagnosed with unresectable advanced/recurrent NSCLC were eligible for study inclusion. Data on adverse events (AEs) and survival were collected electronically. RESULTS Of 401 enrolled patients, 398 were eligible for study inclusion. Most patients were male (68.6%) with a median age of 67.0 years. Patients were predominantly diagnosed with adenocarcinoma (78.1%) or squamous cell carcinoma (16.6%); 46.2% received prior treatment with bevacizumab and 38.7% with immune-checkpoint inhibitors. AEs (any grade) were observed in 323 patients (81.2%; grade ≥ 3: n = 174, 43.7%). The most common AEs (any grade) were malaise (14.3%), decreased appetite (13.0%), and neutrophil count decrease (11.6%). At 12 months from treatment commencement, 93.2% of patients had discontinued, mostly due to progressive disease (53.4%) or AEs (28.3%). The 12-month survival rate was 56.7% (95% confidence interval: 51.5-61.8). CONCLUSIONS Data from real-world settings demonstrate ramucirumab and docetaxel treatment appears to be tolerable and effective in Japanese patients regardless of patient baseline characteristics and prior treatment.

Abstract
BACKGROUND Chemoimmunotherapy has become a standard treatment option for patients with untreated advanced non-small-cell lung cancer (NSCLC). However, numerous patients with advanced NSCLC develop disease progression. Therefore, the selection of second-line treatment after chemoimmunotherapy is crucial for improving clinical outcomes. METHODS Of 88 enrolled patients with advanced NSCLC who received chemoimmunotherapy, we retrospectively evaluated 33 who received second-line chemotherapy after progression of chemoimmunotherapy at six centers in Japan. Among them, 18 patients received docetaxel plus ramucirumab and 15 patients received single-agent chemotherapy. RESULTS The objective response rate in patients treated with docetaxel plus ramucirumab was significantly higher than that in patients treated with a single-agent chemotherapy regimen (55.6% vs. 0%, p < 0.001). The median progression-free survival (PFS) of patients who received docetaxel plus ramucirumab and single-agent chemotherapy was 5.8 months and 5.0 months, respectively (log-rank test p = 0.17). In the docetaxel plus ramucirumab regimen group, patients who responded to chemoimmunotherapy for ≥8.8 months had a significantly longer response to docetaxel plus ramucirumab than those who responded for <8.8 months (not reached vs. 4.1 months, log-rank test p = 0.003). In contrast, in the single-agent chemotherapy group, there was no significant difference in PFS between the ≥8.8- and <8.8-month PFS groups with chemoimmunotherapy (5.0 vs. 1.6 months, log-rank test p = 0.66). CONCLUSION Our retrospective observations suggest that the group with longer PFS with chemoimmunotherapy might be expected to benefit from docetaxel plus ramucirumab treatment in second-line settings for patients with advanced NSCLC.
