Nintedanib plus docetaxel after progression on immune checkpoint inhibitor therapy: insights from VARGADO, a prospective study in patients with lung adenocarcinoma

Canakinumab in combination with docetaxel compared with docetaxel alone for the treatment of advanced non-small cell lung cancer following platinum-based doublet chemotherapy and immunotherapy (CANOPY-2): A multicenter, randomized, double-blind, phase 3 trial

OBJECTIVES

Canakinumab, an interleukin-1 beta inhibitor, previously showed reduced lung cancer incidence and mortality (CANTOS). Here, we compare the efficacy/safety of canakinumab versus placebo in patients with advanced non-small cell lung cancer (NSCLC) who had progressed after platinum-based doublet chemotherapy (PDC) and immunotherapy.

MATERIALS AND METHODS

CANOPY-2, a randomized, double-blind, phase 3 trial, enrolled adult patients with stage IIIB/IV NSCLC, without EGFR or ALK alterations, who had received one prior PDC regimen and one prior programmed death-1/programmed death-ligand 1 inhibitor and experienced subsequent disease progression. Patients were randomized to canakinumab plus docetaxel or placebo plus docetaxel.

RESULTS

A total of 237 patients were randomly allocated: 120 (51 %) to canakinumab and 117 (49 %) to placebo, stratified by histology and prior lines of therapy. Three patients in the placebo arm did not receive study treatment. The trial did not meet its primary endpoint of overall survival: median 10.6 months (95 % confidence interval [CI], 8.2-12.4) for the canakinumab arm and 11.3 months (95 % CI, 8.5-13.8) for the placebo arm (hazard ratio, 1.06 [95 % CI, 0.76-1.48]; one-sided P-value = 0.633). AEs (any grade) were reported in 95 % of patients in the canakinumab group and in 98 % of patients in the placebo group. Grade 3-4 AEs were experienced by 62 % and 64 % of patients in the canakinumab and placebo groups, respectively, and grade 5 AEs were experienced by 8 % and 5 %. Prespecified, post-hoc subgroup analyses showed that patients with undetected circulating tumor DNA (ctDNA) and/or lower levels (< 10 mg/L) of C-reactive protein (CRP) achieved longer progression-free and overall survival than those with detected ctDNA or higher (≥ 10 mg/L) CRP levels. There was no association with treatment arm.

CONCLUSION

Adding canakinumab to docetaxel did not provide additional benefit for patients with advanced NSCLC who had progressed after PDC and immunotherapy.

Effectiveness of PD1/PD-L1 combined with anti-angiogenic drugs in patients with advanced nonsmall cell lung cancer: A systematic review and meta-analysis

Background

Protein-1 (PD-1) and programmed cell death 1 ligand 1 (PD-L1) therapy have become an important treatment approach for patients with advanced nonsmall cell lung cancer (NSCLC), but primary or secondary resistance remains a challenge for some patients. PD-1/PD-L1 combined with anti-angiogenic drugs (AAs) in NSCLC patients have potential synergistic effects, and the survival benefit may vary based on a treatment order. To investigate the efficacy of PD-1/PD-L1 combined with AAs as the treatment for patients with advanced NSCLC.

Materials and Methods

We comprehensively searched EMBASE, PubMed, Web of Science, CNKI, VIP, and Wanfang databases from January 2017 to September 2022. The Cochrane risk bias tool evaluated the quality of included randomized clinical trials. Newcastle-Ottawa-Scale score was used to evaluate the quality of retrospective studies. Publication bias was evaluated by funnel plot, Begg's test, and Egger's test.

Results

Seventeen articles were finally selected, involving 5182 patients. Meta-analysis results showed that PD1/PD-L1 combined with AAs therapy significantly improved progression-free survival (PFS) (hazard ratio [HR] = 0.61, 95% confidence interval [CI]: 0.50-0.75, P < 0.00001), overall survival (OS) (HR = 0.79, 95% CI: 0.71-0.88, P < 0.00001), and objective response rate (ORR) (risk ratio = 0.88, 95% CI: 0.81-0.96, P = 0.004), with the statistically significant difference. The sensitivity analysis demonstrated the robustness of the PFS, ORR, and OS.

Conclusion

The combination of PD-1/PD-L1 inhibitors with AAs in treating advanced patients has exhibited notable therapeutic advantages when contrasted with monotherapy. Specifically, the administration of PD-1/PD-L1 inhibitors in conjunction with AAs, or sequential treatment involving PD-1/PD-L1 followed by AAs, has shown enhanced therapeutic efficacy in this patient population.

Clinical outcomes of ramucirumab plus docetaxel in the treatment of patients with non-small cell lung cancer after immunotherapy: a systematic literature review

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.

Value of chemotherapy post immunotherapy in stage IV non-small cell lung cancer (NSCLC)

BACKGROUND

Lung cancer is the number one cause of mortality among all types of cancer worldwide. Its treatment landscape has shifted from the classic chemotherapy alone to newer regimens based on the discovery of new immunotherapy and targeted therapy drugs. However, chemotherapy is still an option for treatment of advanced non-small cell lung cancer (NSCLC) after progression on immunotherapy alone or in combination with first-line chemotherapy.

METHODS

This is a retrospective study based on chart review of patients diagnosed with advanced NSCLC cases who received Docetaxel as second or third line after being treated by immunotherapy and/or chemotherapy in previous lines. The data was collected from the medical records of physicians' clinics in three different hospital centers in Lebanon over the period of 5 years from July 2015 until December 2020. February 2021 was data analysis cut off time. The main aim was to assess the role of Docetaxel post-chemoimmunotherapy for patients with diagnosed NSCLC.

RESULTS

A total of 21 patients were included in this study. The majority of our patients were males (81%). As for histologic type, most patients had non-squamous lung cancer (67%) as compared to 33% who had squamous lung cancer. Overall, our study reported a 24% response rate to Docetaxel including stable disease and partial response and a median progression free survival (PFS) of 3 months. The mean time interval elapsed from diagnosis to the initiation of Docetaxel was 11.5 months.

CONCLUSION

New therapeutic options should be validated for the treatment of NSCLC in the second and subsequent lines of therapy considering the poor prognosis of this disease. The chemotherapy in second and third line may keep an important role in the treatment after progression on newer agents, but it needs more evidence in prospective studies including a larger number of patients.

Nintedanib plus docetaxel after progression on first-line immunochemotherapy in patients with lung adenocarcinoma: Cohort C of the non-interventional study, VARGADO

BACKGROUND

Immune checkpoint inhibitors (ICIs) with or without chemotherapy represent first-line standard of care for patients with advanced non-small cell lung cancer (NSCLC) without targetable driver mutations. The most appropriate second-line therapy after failing immunochemotherapy remains an open question. Nintedanib, an oral triple angiokinase inhibitor that targets the vascular endothelial growth factor receptor, fibroblast growth factor receptor, and, platelet-derived growth factor receptor, in combination with docetaxel, is approved for treatment of advanced NSCLC (adenocarcinoma histology) following progression on first-line chemotherapy.

METHODS

VARGADO (NCT02392455) is an ongoing, prospective, non-interventional study investigating the efficacy and safety of nintedanib plus docetaxel following first-line chemotherapy with or without ICIs in patients with locally advanced, metastatic, or locally recurrent NSCLC of adenocarcinoma histology. This analysis focuses on Cohort C, which enrolled patients who had received prior first line chemotherapy with ICIs. Patients received second-line docetaxel (75 mg/m²) by intravenous infusion on Day 1, plus oral nintedanib (200 mg twice daily) on Days 2-21 of each 21-day cycle during routine clinical care. The primary endpoint is overall survival (OS) rate 1 year after the start of treatment with nintedanib plus docetaxel. Secondary endpoints include progression-free survival (PFS), OS, and disease control rate (DCR). Safety was also assessed.

RESULTS

Among 137 patients treated, the median age was 63 years (range, 37-84); 57 patients (41.6%) were female, most patients had Eastern Cooperative Oncology Group performance status of 0 (28.5%) or 1 (43.1%); 118 (86.1%) had stage IV NSCLC and 27 (19.7%) had brain metastases. Most (n=120, 87.6%) patients had received pembrolizumab/pemetrexed/platinum-based chemotherapy as first-line treatment. In 80 patients with available response data, the DCR was 72.5% (complete response: 1.3%; partial response: 36.3%; stable disease: 35.0%). Median progression-free survival was 4.8 months (95% confidence interval: 3.7-6.6). OS data were immature. Grade ≥3 treatment-emergent adverse events (TEAEs), serious TEAEs, and TEAEs leading to treatment discontinuation were reported in 62 (45.3%), 50 (36.5%), and 40 patients (29.2%), respectively.

CONCLUSIONS

This analysis indicates that nintedanib plus docetaxel represents an effective second-line treatment option in patients with advanced adenocarcinoma NSCLC following progression on first-line immunochemotherapy. The safety profile was manageable with no unexpected signals.

Real-World Efficacy of Nintedanib Plus Docetaxel After Progression on Immune Checkpoint Inhibitors: Results From the Ongoing, Non-interventional VARGADO Study

AIMS

To evaluate the efficacy and safety of nintedanib plus docetaxel in patients with advanced adenocarcinoma non-small cell lung cancer (NSCLC) who progressed after chemotherapy and immune checkpoint inhibitor (ICI) therapy.

MATERIALS AND METHODS

VARGADO (NCT02392455) is an ongoing, prospective, non-interventional, real-world study of nintedanib plus docetaxel after first-line chemotherapy in the routine clinical treatment of patients with locally advanced, metastatic or locally recurrent adenocarcinoma NSCLC. Data were collected during routine visits. We report the results from cohort B (n = 80), who received third-line nintedanib plus docetaxel after first-line chemotherapy and second-line ICI therapy.

RESULTS

The median duration of follow-up was 12.4 months. Median progression-free survival from initiation of third-line nintedanib plus docetaxel was 6.4 months (95% confidence interval 4.8, 7.3); median overall survival was 12.1 months (95% confidence interval 9.4, 13.5). The 1-year overall survival rate after initiation of third-line nintedanib plus docetaxel treatment (primary end point) was 52% (95% confidence interval 38.0%, 64.4%). Among 64 patients with a documented response, the objective response rate was 50% (n = 32; one complete response and 31 partial responses) and the disease control rate was 86% (n = 55). There were no new safety signals or unexpected toxicities. Among all treated patients, 74% (n = 59) experienced drug-related adverse events, most commonly (nintedanib-related/docetaxel-related) diarrhoea (34%/24%), a decreased white blood cell count (11%/19%) and nausea (13%/16%).

CONCLUSIONS

Nintedanib plus docetaxel demonstrated a high response rate and disease stabilisation in the third-line setting after failure of prior chemotherapy and ICI treatment, with a manageable safety profile. These results suggest that nintedanib plus docetaxel represents an efficient treatment option after failure of prior ICIs. The ongoing VARGADO study provides valuable real-world data to inform clinical decision-making regarding treatment sequencing after chemotherapy and ICI failure in patients with adenocarcinoma NSCLC.

Impact of treatment timing and sequence of immune checkpoint inhibitors and anti-angiogenic agents for advanced non-small cell lung cancer: A systematic review and meta-analysis

OBJECTIVE

Several studies have demonstrated that anti-angiogenic agents (AAs) have the ability to regulate immune-related cells in the tumor microenvironment and may affect the clinical effect of immune checkpoint inhibitors (ICIs). Therefore, we investigated the drug interaction between ICI and AA for advanced non-small cell lung cancer (NSCLC).

MATERIALS AND METHODS

We systematically searched PubMed-MEDLINE, Embase-Scopus, and ISI Web of Science before August 23, 2021. ICI and AA therapy included the concomitant and sequential use of ICIs and AAs. The objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) of patients who received ICI and AA therapy were evaluated and compared to those of patients who received either monotherapy. Subgroup analyses were performed to clarify the cause of heterogeneity; the timing and sequence of ICI and AA administration were predefined as the subgroups.

RESULTS

Thirteen studies involving 2414 patients were included in the meta-analysis. ICI and AA therapy had significantly higher ORR than either monotherapy (OR [95% CI]: 0.61 [0.50-0.74]; p < 0.001; I² = 29%). PFS and OS were favorable benefits in ICI and AA therapy; however, significant heterogeneity was identified in these analyses (I² = 80% and 59%, respectively). According to the administration timing and sequence, ICI immediately after AA showed no PFS and OS benefits compared to ICI monotherapy (HR [95 % CI]: 1.54 [1.14-2.08] and 1.50 [1.04-2.15], respectively), whereas favorable PFS and OS were demonstrated when AA was concomitantly administered with ICI (HR [95 % CI]: 0.57 [0.43-0.76] and 0.80 [0.61-1.05], respectively) or when AA was administered immediately after ICI (HR [95 % CI]: 0.58 [0.34-1.00] and 0.56 [0.40-0.80], respectively).

CONCLUSION

ICI and AA therapy can provide favorable clinical effects compared to either monotherapy; however, ICI administered immediately after AA may not show survival benefits.

Which treatment after first line therapy in NSCLC patients without genetic alterations in the era of immunotherapy?

Cancer immunotherapy has produced an unprecedented durable response rate, thus shifting from traditional doublet chemotherapy to immunotherapy-based treatments with and without chemotherapy as the first line strategies for advanced non-small cell lung cancer patients without a molecular driver. However, the majority of patients do not benefit from the treatment or may relapse after a period of response. As few treatment options are available after failure of cancer immunotherapy, including the combination of chemotherapy and anti-angiogenic drugs, a better understanding of the mechanisms limiting cancer immunotherapy may be of help in the definition of the best second line. Whereas only retrospective data support an immunotherapy rechallenge approach, new combination strategies including immunotherapy and cell-signaling inhibitors or double immunotherapy represent the newest and most promising strategy to overcome primary or acquired resistance to first line immunotherapy.

Silibinin Suppresses Tumor Cell-Intrinsic Resistance to Nintedanib and Enhances Its Clinical Activity in Lung Cancer

The anti-angiogenic agent nintedanib has been shown to prolong overall and progression-free survival in patients with advanced non-small-cell lung cancer (NSCLC) who progress after first-line platinum-based chemotherapy and second-line immunotherapy. Here, we explored the molecular basis and the clinical benefit of incorporating the STAT3 inhibitor silibinin-a flavonolignan extracted from milk thistle-into nintedanib-based schedules in advanced NSCLC. First, we assessed the nature of the tumoricidal interaction between nintedanib and silibinin and the underlying relevance of STAT3 activation in a panel of human NSCLC cell lines. NSCLC cells with poorer cytotoxic responses to nintedanib exhibited a persistent, nintedanib-unresponsive activated STAT3 state, and deactivation by co-treatment with silibinin promoted synergistic cytotoxicity. Second, we tested whether silibinin could impact the lysosomal sequestration of nintedanib, a lung cancer cell-intrinsic mechanism of nintedanib resistance. Silibinin partially, but significantly, reduced the massive lysosomal entrapment of nintedanib occurring in nintedanib-refractory NSCLC cells, augmenting the ability of nintedanib to reach its intracellular targets. Third, we conducted a retrospective, observational multicenter study to determine the efficacy of incorporating an oral nutraceutical product containing silibinin in patients with NSCLC receiving a nintedanib/docetaxel combination in second- and further-line settings (n = 59). Overall response rate, defined as the combined rates of complete and partial responses, was significantly higher in the study cohort receiving silibinin supplementation (55%) than in the control cohort (22%, p = 0.011). Silibinin therapy was associated with a significantly longer time to treatment failure in multivariate analysis (hazard ratio 0.43, p = 0.013), despite the lack of overall survival benefit (hazard ratio 0.63, p = 0.190). Molecular mechanisms dictating the cancer cell-intrinsic responsiveness to nintedanib, such as STAT3 activation and lysosomal trapping, are amenable to pharmacological intervention with silibinin. A prospective, powered clinical trial is warranted to confirm the clinical relevance of these findings in patients with advanced NSCLC.

Real-world efficacy of docetaxel plus nintedanib after chemo-immunotherapy failure in advanced pulmonary adenocarcinoma

Aim: This real-world analysis evaluated docetaxel plus nintedanib in patients with advanced pulmonary adenocarcinoma after chemotherapy and immune checkpoint inhibitor failure, for whom treatment options are limited. Methods: Data were sourced retrospectively from seven German centers. Results: Of 93 patients, overall response rate was 41.4% (disease control rate: 75.9%). Of 57 patients given third-line docetaxel plus nintedanib, overall response rate was 50.0% (disease control rate: 82.7%). Median overall survival following third-line docetaxel plus nintedanib was 8.4 months. Adverse events were consistent with the known safety profile of docetaxel plus nintedanib. Conclusion: To date, this was the largest retrospective, real-world analysis of docetaxel plus nintedanib after chemotherapy-immunotherapy failure, indicating that docetaxel plus nintedanib offers meaningful clinical benefits in this setting.

Efficacy of Combination Docetaxel and Nintedanib in Advanced Non-Small Cell Lung Cancer in Thailand: A Multicenter Study

Introduction

The mainstay systemic treatment for non-oncogenic addictive advanced stage non-small cell lung cancer is chemotherapy. Anti-angiogenic agents are additive compounds that enhance disease control and lead to improvement of overall survival benefit. Recently PD-(L)1 blockage, a checkpoint inhibitor, has been adopted as another line of treatment. A sequential strategy to enhance the efficacy of combination docetaxel and nintedanib after immunotherapy, correlated with genomic mutation, has been explored.

Method

A retrospective cohort study of 56 patients from 8 centers in Thailand who received combination docetaxel and nintedanib via the Thai nintedanib Named Patient Use program was conducted. Demographic characteristics, treatment details, and treatment responses were retrieved from medical records.

Results

The majority of patients were male (62.5%) with adenocarcinoma subtype (88%). Thirty-five percent had sensitizing EGFR mutation. Combination docetaxel and nintedanib was given as second to fourth line of treatment. Median PFS of docetaxel/nintedanib was 5.6 months [95% CI 4.8-6.9]. Median OS of the entire cohort was 22.5 months [95% CI 20.2-31.1]. Among them, only four patients received this combination after immunotherapy which limited the validity of efficacy analysis. Median PFS of those four patients was 7.9 months [range 5.2-9.1] which was slightly higher than the remaining cohort (median PFS 4.5 months, 95% CI: 4.0-6.0, p-value 0.09). Among the adenocarcinoma subtype, a relapse-time of platinum-doublet chemotherapy of more than 6 months was solely indicated as a benefit of combination docetaxel/nintedanib treatment compared to the relapse-time of platinum-doublet chemotherapy of less than 6 months by multivariate HR of PFS 0.32 [95% CI: 0.14-0.68, p-value 0.003].

Conclusion

Combination docetaxel and nintedanib provided more benefit in relapse-time of platinum-doublet chemotherapy of more than 6 months in advanced stage adenocarcinoma lung cancer. Neither EGFR nor ALK alteration influenced the outcome of treatment.

Impact of docetaxel plus ramucirumab on metastatic site in previously treated patients with non-small cell lung cancer: a multicenter retrospective study

Background

Docetaxel (DOC) plus ramucirumab (RAM) has been recommended as an optimal therapy for previously treated patients with non-small cell lung cancer (NSCLC). In a clinical setting, there are few reports about DOC plus RAM, therefore its effect on factors such as Eastern Cooperative Oncology Group (ECOG) performance status (PS) and metastatic sites is still unknown.

Methods

We recruited NSCLC patients who received DOC plus RAM in four medical facilities in Japan from June 2016 to March 2020. We retrospectively investigated the overall response rate (ORR), disease control rate (DCR), and progression-free survival (PFS) of DOC plus RAM and conducted univariate and multivariate analyses using PFS as a dependent factor. Patients were followed up until June 30, 2020.

Results

A total of 237 patients were consecutively enrolled. For all patients, the ORR, DCR, and median PFS were 25.2%, 63.9%, and 4.5 months, respectively. The ORR and DCR for malignant pleural effusion (MPE), lung metastasis, and liver metastasis were 7.7% and 53.8%, 30.3% and 77.5%, and 48.6% and 71.4%, respectively. In the multivariate analysis, MPE, lung metastasis, and liver metastasis were not prognostic factors for poor PFS. However, ECOG-PS 2 or more [hazard ratio (HR): 1.66, 95% confidence interval (CI): 1.14–2.40, P=0.008] and brain metastasis (HR: 1.71, 95% CI: 1.23–2.37, P=0.001) were significant and independent factors associated with shorter PFS.

Conclusions

DOC plus RAM could be an optimal therapy for previous treated NSCLC patients with lung and liver metastasis, and furthermore, should be used carefully for patients with poor ECOG-PS or brain metastasis.

Beyond First-Line Immunotherapy: Potential Therapeutic Strategies Based on Different Pattern Progressions: Oligo and Systemic Progression

First-line immune-checkpoint inhibitor (ICI)-based therapy has deeply changed the treatment landscape and prognosis in advanced non-small cell lung cancer (aNSCLC) patients with no targetable alterations. Nonetheless, a percentage of patients progressed on ICI as monotherapy or combinations. Open questions remain on patients' selection, the identification of biomarkers of primary resistance to immunotherapy and the treatment strategies to overcome secondary resistance to first-line immunotherapy. Local ablative approaches are the main therapeutic strategies in oligoprogressive disease, and their role is emerging in patients treated with immunotherapy. Many therapeutic strategies can be adapted in aNSCLC patients with systemic progression to personalize the treatment approach according to re-characterization of the tumors, previous ICI response, and type of progression. This review's aim is to highlight and discuss the current and potential therapeutic approaches beyond first-line ICI-based therapy in aNSCLC patients based on the pattern of disease progression (oligoprogression versus systemic progression).

Immune Modulation in Lung Cancer: Current Concepts and Future Strategies

Cancer immunotherapy represents the most dynamic field of biomedical research currently, with thoracic immuno-oncology as a forerunner. PD-(L)1 inhibitors are already part of standard first-line treatment for both non-small-cell and small-cell lung cancer, while unprecedented 5-year survival rates of 15-25% have been achieved in pretreated patients with metastatic disease. Evolving strategies are mainly aiming for improvement of T-cell function, increase of immune activation in the tumor microenvironment (TME), and supply of tumor-reactive lymphocytes. Several novel therapeutics have demonstrated preclinical efficacy and are increasingly used in rational combinations within clinical trials. Two overarching trends dominate: extension of immunotherapy to earlier disease stages, mainly as neoadjuvant treatment, and a shift of focus towards multivalent, individualized, mutatome-based antigen-specific modalities, mainly adoptive cell therapies and cancer vaccines. The former ensures ample availability of treated and untreated patient samples, the latter facilitates deeper mechanistic insights, and both in combination build an overwhelming force that is accelerating progress and driving the greatest revolution cancer medicine has seen so far. Today, immune modulation represents the most potent therapeutic modality in oncology, the most important topic in clinical and translational cancer research, and arguably our greatest, meanwhile justified hope for achieving cure of pulmonary neoplasms and other malignancies in the next future.

Non-interventional LUME-BioNIS study of nintedanib plus docetaxel after chemotherapy in adenocarcinoma non-small cell lung cancer: A subgroup analysis in patients with prior immunotherapy

OBJECTIVES

To evaluate the effectiveness and safety of nintedanib plus docetaxel in patients with advanced adenocarcinoma non-small cell lung cancer (NSCLC) previously treated with both chemo- and immunotherapy.

MATERIALS AND METHODS

LUME-BioNIS is a European, prospective, multicenter, non-interventional study of patients with advanced adenocarcinoma NSCLC, who initiated nintedanib plus docetaxel after first-line chemotherapy in routine practice according to the approved nintedanib EU label. The primary objective is to explore whether molecular biomarkers can predict overall survival (OS). Information on clinical or radiologic progression and death, and adverse drug reactions (ADRs)/fatal adverse events (AEs) was collected during follow-up. Here, we report a subgroup analysis evaluating outcomes in immunotherapy-pretreated patients.

RESULTS

Of 260 enrolled patients, 67 (25.8%) had prior immunotherapy and were included in this subgroup analysis. Prior immunotherapy was administered in first-line in 20 patients (29.9%; combined with chemotherapy in 4 patients [6.0%]) and later-lines in 47 patients (70.1%), and most commonly comprised nivolumab (39 patients; 58.2%), atezolizumab (14 patients; 20.9%) and pembrolizumab (11 patients; 16.4%). Nintedanib plus docetaxel was given in second-line in 10 patients (14.9%) and in later-lines in 57 patients (85.1%). Median OS was 8.8 months (95% confidence interval [CI]: 7.0-11.5) and median progression-free survival (PFS) was 4.6 months (95% CI: 3.5-5.7). Among 55 patients with available data, rates of objective response and disease control were 18.2% and 78.2%, respectively. In 65 patients evaluable for safety, the most common on-treatment ADRs/AEs were malignant neoplasm progression (19 patients; 29.2%), diarrhea (21 patients; 32.3%) and nausea (10 patients; 15.4%).

CONCLUSIONS

Used according to the approved nintedanib label in routine practice, nintedanib plus docetaxel demonstrated clinical effectiveness, with no unexpected safety findings, in patients with prior chemotherapy and first- or later-line immunotherapy. These data add to the real-world evidence that can inform clinical decisions in the changing therapeutic landscape.

[Immunotherapy of metastatic non-small cell lung cancer from first line to resistance and its management]

Immunotherapy alone or in combination with chemotherapy is now an integral part of the treatment of metastatic NSCLC. This treatment is transforming the management of these cancers, with 20-30% of patients achieving long survival. However, disease progression under treatment is still the rule for the majority of patients, raising problems both in understanding its mechanisms and in subsequent appropriate management. This study examines current therapeutic options and proposes solutions to circumvent resistance to immunotherapy. The mechanisms of resistance to these treatments is also analysed.

Anti-angiogenic agents in the age of resistance to immune checkpoint inhibitors: Do they have a role in non-oncogene-addicted non-small cell lung cancer?

The introduction of licensed front-line immunotherapies has heralded a new era for the treatment of non-oncogene-addicted, advanced non-small cell lung cancer (NSCLC). Yet as with all evolutions in clinical management, changes in practice can outpace the availability of the clinical evidence needed to inform subsequent therapeutic decision making. At the time of writing, there is limited available evidence on the optimum therapeutic options after progression on immunotherapy. Further research is needed to define mechanisms of immunotherapy resistance in patients with advanced NSCLC, and to understand the implications for subsequent treatment response. Pending the availability of robust clinical data and proven therapeutic options to underpin an optimized therapeutic pathway after progression on immunotherapy, attention must turn to the potential utility of currently licensed agents and any available supporting clinical data in this setting. Within this context we review the mechanistic arguments and supporting evidence for the use of anti-angiogenic agents as a means of targeting immunosuppression within the tumor microenvironment. We consider whether VEGF inhibition may help to normalize the tumor vasculature and to address immunosuppression - reinstating, and potentially enhancing, the effect of subsequent therapies. We also highlight evidence needs and signpost ongoing trials that should enable current clinical opinion in this area to be replaced by robust, evidence-based guidance.

Treatment options after first-line immunotherapy in metastatic NSCLC

Introduction: The recent approvals of checkpoint inhibitors as single agents or in combination with chemotherapy with programmed death ligand 1 expression of < or ≥1% have challenged clinicians when it is time to begin a metastatic lung cancer patient in second-line therapy. The advantages given by immunotherapy over conventional chemotherapy such as improved overall survival and a better toxicity profile make the second-line clinical scenario more difficult for a patient who faces a likely inferior regimen as well as toxicity which may significantly impact the quality of life.Areas covered: Options given today by the National Comprehensive Cancer Network are very limited, and essentially, we go back to conventional cytotoxic agents alone or in combination with biological agents if possible. In this article, we discuss the actual treatment available for this difficult scenario and some of the ongoing trials which aim to address this dilemma.Expert commentary: This is an unmet need in lung cancer management; we need a better understanding of the mechanism of resistance to immunotherapy so we can target them once the patient moves to second-line treatment.
