Brief Report on Global Clinician Practices in the First-Line Management of Metastatic Non-Small Cell Lung Cancer.

INTRODUCTION: In the dynamic landscape of metastatic NSCLC (mNSCLC) management, marked by several frontline options and the integration of next generation sequencing (NGS) for informed decision-making, barriers persist despite advancements. This includes challenges in clinical trial recruitment. To gain global insights into clinicians' practices, we conducted a survey on their testing and management approaches for patients with mNSCLC. METHODS: The survey, conducted from July 12 to August 20, 2023, utilized multiple-choice questions and qualitative research questions, employing the Likert Scale for comprehensive insights. RESULTS: A total of 127 individuals responded, with 72% affiliated with academic health systems, and 55% practicing in the USA. Regarding testing practices, 93% consistently ordered NGS for non-squamous histology, while 54% did so for squamous cell histology. Concurrent tissue and liquid biopsies were routinely ordered by 28%, while 39% reported ordering both testing platforms concurrently for select cases only. Respondents cited logistical barriers, such as insufficient tissue and lack of infrastructure, as the most common hindrance to molecular testing (76%), followed by reimbursement challenges (56%) and concerns about delayed turnaround time (50%). While most respondents were confident in interpreting NGS results, 22% lacked confidence. Concerning treatment decisions, 72% preferred awaiting molecular testing results before initiating systemic therapy. Less than 50% routinely referred patients for clinical trials in the frontline setting for mNSCLC. For patients with disease expressing high PD-L1 levels, most oncologists preferred pembrolizumab monotherapy. For disease with low PD-L1 expression, a platinum doublet chemotherapy regimen combined with pembrolizumab was favored. In disease cases with negative PD-L1 expression, a platinum doublet chemotherapy regimen with pembrolizumab was preferred. Key factors influencing oncologists' preferred immune checkpoint inhibitor (ICI) included experience with one ICI over another, preferred status per national guidelines, availability of trial data with a significant follow-up period, and consideration of drug cost. CONCLUSION: Although this study demonstrates an improved awareness and adoption of ordering NGS for the management of mNSCLC, it underscores the persistence of various barriers that must be addressed to improve upon the quality of care for patients diagnosed with mNSCLC.

Frontline pembrolizumab monotherapy for metastatic non-small cell lung cancer with PD-L1 expression ≥50%: real-world outcomes in a US community oncology setting.

Background: This study investigated real-world time on treatment (rwToT) and overall survival (OS) for patients with metastatic non-small cell lung cancer (mNSCLC) who initiated first-line (1L) pembrolizumab monotherapy. We also explored discontinuation reasons and subsequent treatments, stratified by number of cycles among those who completed ≥17 cycles of 1L pembrolizumab. Methods: Patients with mNSCLC without actionable genetic aberrations, Eastern Cooperative Oncology Group performance status (ECOG PS) 0-2 and unknown, and PD-L1 TPS ≥ 50% starting 1L pembrolizumab monotherapy between 24-Oct-2016 and 31-Dec-2018 within The US Oncology Network were identified retrospectively and evaluated using structured data, with a data cutoff of 30-Sep-2021. Patient characteristics and disposition were summarized using descriptive statistics. OS and rwToT were evaluated using Kaplan-Meier method for all ECOG PS and PS 0-1. A subgroup of patients who completed ≥17 cycles were evaluated using supplemental chart review data to discern reasons for discontinuation. Results: Of the 505 patients with mNSCLC with PD-L1 TPS ≥50%, 61% had ECOG PS 0-1, 23% had ECOG PS 2, and 65% had nonsquamous histology. Median rwToT and OS of pembrolizumab were 7.0 (95% CI, 6.0-8.4) months and 24.5 (95% CI, 20.1-29.3) months, respectively. In the subgroup with ECOG PS 0-1, they were 7.6 months (95% CI, 6.2-9.2) and 28.8 months (95% CI, 22.4-37.5), respectively. Of the 103 patients who completed ≥17 cycles, 57 (55.3%) patients received 17 - 34 cycles and 46 (44.7%) patients received ≥35 cycles. Approximately 7.7% of the study population received pembrolizumab beyond 35 cycles. Most common reasons for discontinuation were disease progression (38.6%) and toxicity (19.3%) among patients who received 17-34 cycles of pembrolizumab, and disease progression (13.0%) and completion of therapy (10.9%) among patients who received ≥35 cycles. Conclusion: Consistent with findings from KEYNOTE-024 and other real-world studies, this study demonstrates the long-term effectiveness of pembrolizumab monotherapy as 1L treatment for mNSCLC with PD-L1 TPS ≥50%. Among patients who completed ≥17 cycles, nearly half completed ≥35 cycles. Disease progression and toxicity were the most common reasons for discontinuation among patients who received 17-34 cycles of pembrolizumab. Reasons for discontinuation beyond 35 cycles need further exploration.

Examining crossover and postprotocol therapies in first-line immunotherapy trials in non-small cell lung cancer (NSCLC).

BACKGROUND: Immune checkpoint inhibitor (ICI) therapy has led to significant improvement in outcomes for patients with nononcogene-driven advanced non-small cell lung cancer (NSCLC). The rate of crossover and receipt of postprotocol ICI in frontline trials for advanced NSCLC has not been systematically evaluated. METHODS: ClinicalTrials.gov was used to identify phase 3 studies evaluating the use of immunotherapy or combination chemoimmunotherapy against chemotherapy alone in the frontline management of advanced NSCLC. Data on outcomes, rate of crossover and/or subsequent post-protocol receipt of immunotherapy, and the start dates of these clinical trials were then extracted. RESULTS: Twenty-three frontline trials in nononcogene-driven advanced NSCLC were identified. Six trials with ICI monotherapy/dual ICI therapy and 17 trials evaluating chemotherapy/ICI in first-line advanced NSCLC were included in the analysis. The crossover rate ranged 0% to 54% in ICI monotherapy/dual ICI trials and 0% to 52% in chemotherapy/ICI trials. Nineteen of 23 trials provided information on subsequent postprotocol therapies. Among the trials not allowing crossover, postprotocol ICI was administered to 17% to 45.8% of patients. Information regarding the eventual receipt of ICI therapy was available for 22 of 23 trials. Of 6631 patients, 2507 (37.8%) randomized to the control arm eventually received ICI therapy. CONCLUSION: The rate of crossover and postprotocol ICI use was low in frontline trials for first-line NSCLC incorporating ICI. Given the proven survival overall survival of ICI in a broad population, there is a need to ensure availability of this life-prolonging therapy in future trials, either by crossover treatment or postprotocol administration.

Rapid Advances in Resectable Non-Small Cell Lung Cancer: A Narrative Review.

Importance: A series of high-profile clinical trials for patients with resectable early-stage non-small cell lung cancer (NSCLC) have recently changed the standard of care in this setting. Specifically, studies have demonstrated statistically and clinically significant improvements in efficacy with the targeted therapy for adjuvant osimertinib in patients with resected NSCLC harboring an epidermal growth factor receptor (EGFR) genomic abnormality (GA), whereas trials with chemotherapy combined with nivolumab in the neoadjuvant setting and others testing atezolizumab or pembrolizumab as adjuvant therapy have all demonstrated improvements in event-free survival (EFS) (for neoadjuvant therapy) or disease-free survival (DFS) (for adjuvant therapy). These trials introduce many open questions about how to apply these findings in clinical practice. Observations: Treatment with adjuvant osimertinib for 3 years was associated with significant improvement in both DFS and overall survival (OS), but the erosion of the DFS benefit after the duration of treatment ends suggests a potential value for more longitudinal treatment. The potential value of highly effective targeted therapies as adjuvant therapy for other GAs has a compelling rationale but no data at this time. Adjuvant atezolizumab or pembrolizumab, generally administered for 1 year after postoperative chemotherapy, are appropriate considerations, but only atezolizumab for patients with tumor programmed death-ligand 1 (PD-L1) levels of 50% has demonstrated a benefit in OS. Neoadjuvant chemotherapy with nivolumab offers a strong EFS benefit, a shorter interval of treatment, and radiographic and pathologic feedback for patients with resectable stage IB to IIIA NSCLC, although very recent randomized clinical trials of perioperative immunotherapy both combined with chemotherapy preoperatively and administered postoperatively highlight the debatable value of adjuvant immunotherapy after prior chemoimmunotherapy. Improved tumor shrinkage rates with neoadjuvant chemoimmunotherapy suggest the possibility that criteria for resectability may potentially be redefined in anticipation of a good response to neoadjuvant chemoimmunotherapy. Conclusions and Relevance: Developments in resectable NSCLC have arrived so rapidly that they have also created practical challenges of identifying optimal patients and prioritizing options among these new competing standards. In some cases, practical management requires clinical judgment and discussion with the patient to cover the gaps in prospective data. Caution should be exerted when extrapolating beyond the available data.

Perioperative Therapy for Resectable Non-Small-Cell Lung Cancer: Weighing Options for the Present and Future.

Anatomic surgical resection followed by cisplatin-based platinum-doublet adjuvant chemotherapy has been a long-standing standard of care for patients with early-stage, resectable non-small-cell lung cancer (NSCLC). More recently, incorporating of immunotherapy and targeted therapy in the perioperative setting has demonstrated improved disease-free or event-free survival in biomarker-defined subsets of patients. This article summarizes the results of major trials that led to approvals beyond chemotherapy in the perioperative setting. Alongside adjuvant osimertinib as a favored strategy for patients with EGFR mutation-positive NSCLC, there are competing potential standards of care for integrating immunotherapy in the neoadjuvant versus adjuvant setting, with advantages and disadvantages for each strategy. Emerging data in the coming years will provide further insight that may potentially lead to a combination of neoadjuvant and adjuvant treatment for many patients. Future trials should focus on clarifying the benefit of each component of treatment, defining an optimal treatment duration, and incorporating minimal residual disease to optimize treatment decisions.
