RESUMO
BACKGROUND: The combination of platinum-based chemotherapy and an antibody to PD-1 or to its ligand PD-L1, with or without an antibody to CTLA-4, has improved the survival of individuals with metastatic non-small-cell lung cancer (NSCLC). However, no randomised controlled trial has evaluated the survival benefit of adding a CTLA-4 inhibitor to platinum-based chemotherapy plus a PD-1 or PD-L1 inhibitor. METHODS: This open-label, randomised, phase 3 trial was conducted at 48 hospitals in Japan. Eligible patients were aged 20 years or older with previously untreated advanced NSCLC and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients with known driver oncogenes were excluded. Participants were randomly assigned (1:1) to receive platinum-based chemotherapy (four cycles) plus pembrolizumab (pembrolizumab group) or platinum-based chemotherapy (two cycles) plus nivolumab-ipilimumab (nivolumab-ipilimumab group). The primary endpoint was overall survival and assessed in all randomly assigned patients on an intention-to-treat basis. The trial is registered in the Japan Registry for Clinical Trials, jRCTs031210013, and is now closed to new enrolment and is ongoing. FINDINGS: Between patient accrual initiation on April 6, 2021, and discontinuation of the trial on March 30, 2023, 11 (7%) of 148 patients in the nivolumab-ipilimumab group had a treatment-related death. Because of the high number of treatment-related deaths, patient accrual was terminated early, resulting in 295 patients (236 [80%] male and 59 [20%] female) enrolled; the primary analysis was done on the basis of 117 deaths (fewer than the required 329 deaths). By May 25, 2023 (data cutoff), overall survival did not differ significantly between the nivolumab-ipilimumab group and the pembrolizumab group (median 23·7 months [95% CI 17·6-not estimable] vs 20·5 months [17·6-not estimable], respectively; hazard ratio 0·98 [90% CI 0·72-1·34]; p=0·46). Non-haematological adverse events of grade 3 or worse occurred in 87 (60%) of 146 patients in the nivolumab-ipilimumab group and 59 (41%) of 144 patients in the pembrolizumab group. The pembrolizumab group tended to have a better quality of life compared with the nivolumab-ipilimumab group. INTERPRETATION: The safety and efficacy data suggest an unfavourable benefit-risk profile for nivolumab-ipilimumab combined with platinum-based chemotherapy relative to pembrolizumab combined with platinum-based chemotherapy as a first-line treatment for patients with advanced NSCLC, although a definitive conclusion awaits an updated analysis of overall survival.

RESUMO
BACKGROUND: The expansion of preoperative immunochemotherapy has led to an increase in the number of patients with lung cancer receiving immune checkpoint inhibitors (ICIs). Therefore, oncologists should manage a variety of immune-related adverse events (irAEs). One of the rare, life-threatening, and recently proposed irAEs is cytokine release syndrome (CRS). Although the standard treatment of irAE is systemic administration of steroids, it has been suggested that tocilizumab may be an effective treatment option for CRS. CASE: This case describes a 69-year-old man with stage IIIA lung adenocarcinoma who received chemotherapy and nivolumab, which is an ICI, as neoadjuvant immunochemotherapy. After the first administration, the patient developed severe skin rash, fever, and arthralgia. We suspected irAEs and administered systemic steroids. However, fever and arthralgia did not improve, although the skin rash disappeared. These were also significant challenges for surgery. Noting the elevated levels of inflammatory cytokines, we consulted a rheumatologist. Finally, we decided to terminate neoadjuvant therapy after one cycle and administer tocilizumab. Tocilizumab dramatically improved the patient's symptoms and allowed him to undergo radical surgery. Pathological findings revealed that the patient achieved a major pathological response. CONCLUSION: This indicates the potential effectiveness of early tocilizumab administration for ICI-induced CRS, even in mild cases.

Although comprehensive biomarker testing is recommended for all patients with advanced/metastatic non-small cell lung cancer (NSCLC) before initiation of first-line treatment, tissue availability can limit testing. Genomic testing in liquid biopsies can be utilized to overcome the inherent limitations of tissue sampling and identify the most appropriate biomarker-informed treatment option for patients. The Blood First Assay Screening Trial is a global, open-label, multicohort trial that evaluates the efficacy and safety of multiple therapies in patients with advanced/metastatic NSCLC and targetable alterations identified by liquid biopsy. We present data from Cohort D (ROS1-positive). Patients ≥18 years of age with stage IIIB/IV, ROS1-positive NSCLC detected by liquid biopsies received entrectinib 600 mg daily. At data cutoff (November 2021), 55 patients were enrolled and 54 had measurable disease. Cohort D met its primary endpoint: the confirmed objective response rate (ORR) by investigator was 81.5%, which was consistent with the ORR from the integrated analysis of entrectinib (investigator-assessed ORR, 73.4%; data cutoff May 2019, ≥12 months of follow-up). The safety profile of entrectinib was consistent with previous reports. These results demonstrate consistency with those from the integrated analysis of entrectinib in patients with ROS1-positive NSCLC identified by tissue-based testing, and support the clinical value of liquid biopsies to inform clinical decision-making. The integration of liquid biopsies into clinical practice provides patients with a less invasive diagnostic method than tissue-based testing and has faster turnaround times that may expedite the reaching of clinical decisions in the advanced/metastatic NSCLC setting.

Introduction: Lorlatinib was found to have improved efficacy versus crizotinib in the global phase 3 CROWN study (NCT03052608). Similar results were revealed for the Japanese population as for the overall population. We present results from the unplanned 3-year follow-up from the CROWN study in Japanese patients. Methods: Patients were randomized to either lorlatinib 100 mg once daily (n = 25) or crizotinib 250 mg twice daily (n = 23). The primary end point was progression-free survival assessed by blinded independent central review. Secondary end points included objective and intracranial responses assessed by blinded independent central review and safety. Results: At the data cutoff of September 20, 2021, median progression-free survival was not reached with lorlatinib and 11.1 months with crizotinib (hazard ratio = 0.36). Objective response rate was 72.0% with lorlatinib and 52.2% with crizotinib. For patients with baseline brain metastases, intracranial response rate was 100.0% versus 28.6% with lorlatinib versus crizotinib. Nine patients in the lorlatinib group received more than or equal to 1 subsequent anticancer systemic therapy, with ALK tyrosine kinase inhibitor as the most common first subsequent therapy. The safety profile was consistent with that reported previously, with no new safety signals. Conclusions: This updated analysis in the Japanese population revealed prolonged benefits of lorlatinib over crizotinib in patients with treatment-naive advanced ALK-positive NSCLC with and those without brain metastases.
RESUMO
PURPOSE: E7389-LF is a liposomal formulation of eribulin that contributes to tumor vascular remodeling. The phase II part of this phase Ib/II study assessed the efficacy/safety of E7389-LF in combination with nivolumab in several disease cohorts; herein, we report results from the small cell lung cancer (SCLC) cohort. EXPERIMENTAL DESIGN: Patients with unresectable/measurable SCLC and disease progression with first-line platinum-based chemotherapy with/without an immune checkpoint inhibitor (ICI) were enrolled to receive E7389-LF 2.1 mg/m2 plus nivolumab 360 mg intravenously every 3 weeks. The primary objective of this part was to assess the objective response rate (ORR). Secondary objectives included assessments of safety and progression-free survival (PFS); exploratory assessments included overall survival (OS) and biomarkers. RESULTS: Thirty-four patients were enrolled. By the data cut-off date (May 31, 2022), 29 (85.3%) had discontinued. Efficacy/biomarker analyses included 33 patients (1 had their diagnosis changed postenrollment); the ORR of E7389-LF plus nivolumab was 24.2% [95% confidence interval (CI): 11.1-42.3], the median PFS was 3.98 months (95% CI: 2.63-4.40), and, at a median follow-up of 10.6 months, the median OS was not reached (95% CI: not estimable). Notably, 27 of 33 patients (81.8%) had received an ICI as their prior first-line therapy. Treatment-related, treatment-emergent adverse events occurred in 97.1% (any grade) and 82.4% (grade ≥3) of enrolled patients; the most common event was neutropenia. Changes in vascular and immune-related plasma markers were observed. CONCLUSIONS: E7389-LF 2.1 mg/m2 in combination with nivolumab 360 mg every 3 weeks showed notable antitumor activity as second-line therapy for SCLC; no new safety signals were observed compared with either agent as monotherapy. SIGNIFICANCE: This phase II part of a phase Ib/II study assessed liposomal eribulin (E7389-LF) plus nivolumab in 34 patients with pretreated SCLC; 8 of 33 evaluable patients (including 6/27 pretreated with ICIs) had objective responses. The combination was tolerable; increases in vasculature-related biomarkers tended to correlate with responses.

BACKGROUND: Anaplastic lymphoma kinase (ALK)-positive lung cancer has a better long-term prognosis with ALK-inhibitor than other lung cancers. However, resistance to ALK-inhibitors and the control of metastases in the central nervous system (CNS) remain to be a challenge in the management of ALK-positive lung cancer. CASE: We present the case of a 23-year-old man who developed multiple brain metastases while receiving alectinib treatment for ALK-positive lung cancer. After 3 months of lorlatinib initiation, brain metastases disappeared, and complete response (CR) was maintained. CONCLUSION: While lorlatinib can be used as first line therapy, this drug may be considered as second line or later option for patients with multiple brain metastases if the patient has already been treated with other ALK-inhibitors since lorlatinib is thought to have good CNS penetration. This treatment option should be verified by further research.

BACKGROUND: According to the results of the KEYNOTE-407 trial, pembrolizumab plus platinum-based chemotherapy is the standard of care for patients with previously untreated advanced squamous non-small-cell lung cancer (NSCLC). Ubenimex, a potent aminopeptidase inhibitor, is an oral drug with immunostimulatory and antitumor activities. We aim to assess the safety and efficacy of ubenimex in combination with pembrolizumab, nab-paclitaxel, and carboplatin in patients with previously untreated advanced squamous NSCLC. PATIENTS AND METHODS: This prospective, single-arm, multicenter, phase II clinical trial is conducted to confirm the tolerability and efficacy of the tested drugs. Patients with previously untreated advanced squamous NSCLC will receive a predetermined daily dose of ubenimex orally plus 4 cycles of pembrolizumab, nab-paclitaxel, and carboplatin, followed by continuous administration of ubenimex and pembrolizumab for a maximum of 2 years. To confirm tolerability, the daily dose of ubenimex will begin at level 1 (30 mg), which will be increased to levels 2 (60 mg) and 3 (120 mg) according to the escalation criteria, with a standard 3 + 3 design for achieving the target dose-limiting toxicity rate of 33%. The efficacy, safety, and tolerability of ubenimex at the determined dose level will be analyzed. The primary endpoint of the efficacy evaluation will be the objective response rate assessed by an independent review committee. CONCLUSIONS: This is the first study to evaluate the efficacy and safety of ubenimex combined with pembrolizumab, nab-paclitaxel, and carboplatin in patients with previously untreated advanced squamous NSCLC. The results will help devise future treatment strategies.

Importance: The combination of an antibody to programmed cell death-1 (PD-1) or to its ligand (PD-L1) with chemotherapy is the standard first-line treatment for metastatic non-small cell lung cancer (NSCLC). Bevacizumab is expected to enhance the efficacy not only of chemotherapy but also of PD-1/PD-L1 antibodies through blockade of vascular endothelial growth factor-mediated immunosuppression, but further data are needed to support this. Objective: To evaluate the efficacy and safety of bevacizumab administered with platinum combination therapy and atezolizumab in patients with advanced nonsquamous NSCLC. Design, Setting, and Participants: An open-label phase 3 randomized clinical trial was conducted at 37 hospitals in Japan. Patients with advanced nonsquamous NSCLC without genetic driver alterations or those with genetic driver alterations who had received treatment with at least 1 approved tyrosine kinase inhibitor were enrolled between January 20, 2019, and August 12, 2020. Interventions: Patients were randomly assigned to receive either atezolizumab plus carboplatin with pemetrexed (APP) or atezolizumab, carboplatin plus pemetrexed, and bevacizumab (APPB). After 4 cycles of induction therapy, maintenance therapy with atezolizumab plus pemetrexed or with atezolizumab, pemetrexed, and bevacizumab was administered until evidence of disease progression, development of unacceptable toxic effects, or the elapse of 2 years from the initiation of protocol treatment. Main Outcomes and Measures: The primary end point was progression-free survival (PFS) as assessed by blinded independent central review (BICR) in the intention-to-treat (ITT) population. Results: A total of 412 patients were enrolled (273 men [66%]; median age, 67.0 [range, 24-89] years) and randomly assigned, with 205 in the APPB group and 206 in the APP group of the ITT population after exclusion of 1 patient for good clinical practice violation. The median BICR-assessed PFS was 9.6 months with APPB vs 7.7 months with APP (stratified hazard ratio [HR], 0.86; 95% CI, 0.70-1.07; 1-sided stratified log-rank test; P = .92). According to prespecified subgroup analysis of BICR-assessed PFS, an improved PFS with APPB vs APP was apparent specifically in driver oncogene-positive patients (median, 9.7 vs 5.8 months; stratified HR, 0.67; 95% CI, 0.46-0.98). Toxic effects related to bevacizumab were increased in the APPB group. Conclusions and Relevance: The findings of this trial did not show superiority of APPB over APP for patients with nonsquamous NSCLC; however, this regimen showed a similar tolerability and improved survival relative to APP in patients with driver oncogenes. Trial Registration: Japan Registry of Clinical Trials Identifier: jRCT2080224500.

In the open-label, phase III CheckMate 816 study (NCT02998528), neoadjuvant nivolumab plus chemotherapy demonstrated statistically significant improvements in event-free survival (EFS) and pathological complete response (pCR) versus chemotherapy alone in patients with resectable non-small-cell lung cancer (NSCLC). Here we report efficacy and safety outcomes in the Japanese subpopulation. Patients with stage IB-IIIA, resectable NSCLC were randomized 1:1 to nivolumab plus chemotherapy or chemotherapy alone for three cycles before undergoing definitive surgery within 6 weeks of completing neoadjuvant treatment. The primary end-points (EFS and pCR) and safety were assessed in patients enrolled at 16 centers in Japan. Of the Japanese patients randomized, 93.9% (31/33) in the nivolumab plus chemotherapy arm and 82.9% (29/35) in the chemotherapy arm underwent surgery. At 21.5 months' minimum follow-up, median EFS was 30.6 months (95% confidence interval [CI], 16.8-not reached [NR]) with nivolumab plus chemotherapy versus 19.6 months (95% CI, 8.5-NR) with chemotherapy; hazard ratio, 0.60 (95% CI, 0.30-1.24). The pCR rate was 30.3% (95% CI, 15.6-48.7) versus 5.7% (95% CI, 0.7-19.2), respectively; odds ratio, 7.17 (95% CI, 1.44-35.85). Grade 3/4 treatment-related adverse events were reported in 59.4% versus 42.9% of patients, respectively, with no new safety signals identified. Neoadjuvant nivolumab plus chemotherapy resulted in longer EFS and a higher pCR rate versus chemotherapy alone in Japanese patients, consistent with findings in the global population. These data support nivolumab plus chemotherapy as a neoadjuvant treatment option in Japanese patients with resectable NSCLC.

INTRODUCTION: Lenvatinib plus pembrolizumab was found to have antitumor activity and acceptable safety in previously treated metastatic NSCLC. We evaluated first-line lenvatinib plus pembrolizumab versus placebo plus pembrolizumab in metastatic NSCLC in the LEAP-007 study (NCT03829332/NCT04676412). METHODS: Patients with previously untreated stage IV NSCLC with programmed cell death-ligand 1 tumor proportion score of at least 1% without targetable EGFR/ROS1/ALK aberrations were randomized 1:1 to lenvatinib 20 mg or placebo once daily; all patients received pembrolizumab 200 mg every 3 weeks for up to 35 cycles. Primary end points were progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 and overall survival (OS). We report results from a prespecified nonbinding futility analysis of OS performed at the fourth independent data and safety monitoring committee review (futility bound: one-sided p < 0.4960). RESULTS: A total of 623 patients were randomized. At median follow-up of 15.9 months, median (95% confidence interval [CI]) OS was 14.1 (11.4â19.0) months in the lenvatinib plus pembrolizumab group versus 16.4 (12.6â20.6) months in the placebo plus pembrolizumab group (hazard ratio = 1.10 [95% CI: 0.87â1.39], p = 0.79744 [futility criterion met]). Median (95% CI) PFS was 6.6 (6.1â8.2) months versus 4.2 (4.1â6.2) months, respectively (hazard ratio = 0.78 [95% CI: 0.64â0.95]). Grade 3 to 5 treatment-related adverse events occurred in 57.9% of patients (179 of 309) versus 24.4% (76 of 312). Per data and safety monitoring committee recommendation, the study was unblinded and lenvatinib and placebo were discontinued. CONCLUSIONS: Lenvatinib plus pembrolizumab did not have a favorable benefitârisk profile versus placebo plus pembrolizumab. Pembrolizumab monotherapy remains an approved treatment option in many regions for first-line metastatic NSCLC with programmed cell death-ligand 1 tumor proportion score of at least 1% without EGFR/ALK alterations.

Introduction: Necitumumab plus gemcitabine and cisplatin (GCN) is a standard therapy for patients with advanced lung squamous cell carcinoma (LSqCC). However, the efficacy and tolerability of GCN in second-line or later treatment for patients previously treated with immune checkpoint inhibitors (ICIs) remain unknown. Methods: This multicenter, retrospective, cohort study assessed the efficacy and tolerability of GCN initiated between November 1, 2019 and March 31, 2022 as second-line to fourth-line treatment in patients with advanced LSqCC who had been pretreated with ICIs. The primary end point was progression-free survival (PFS). Results: A total of 93 patients from 35 institutions in Japan were enrolled. The median PFS, median overall survival (OS), and objective response rate were 4.4 months (95% confidence interval [CI]: 3.8-5.3), 13.3 months (95% CI: 9.6-16.5), and 27.3% (95% CI: 18.3-37.8), respectively. The median PFS, median OS, and objective response rate for second-line, third-line, and fourth-line treatment groups were 4.8 months, 3.8 months, and 4.3 months (p = 0.24); 15.7 months, 11.6 months, and 10.1 months (p = 0.06); and 31.0%, 13.6%, and 37.5% (p = 0.22), respectively. The severity of GCN-related skin disorders was associated with longer PFS (p < 0.05) and OS (p < 0.05). The frequencies of grade ≥3 skin disorders, hypomagnesemia, pneumonitis, and febrile neutropenia were 16.1%, 7.5%, 1.1%, and 4.3%, respectively. There were no treatment-related deaths. Conclusions: GCN for ICI-pretreated patients with LSqCC seems tolerable and offers promising efficacy regardless of treatment line, and ICI pretreatment might enhance GCN efficacy.
RESUMO
BACKGROUND: Osimertinib is a third-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) that is selective for EGFR-TKI-sensitizing and EGFR T790M resistance mutations. Evidence suggests that the addition of chemotherapy may extend the benefits of EGFR-TKI therapy. METHODS: In this phase 3, international, open-label trial, we randomly assigned in a 1:1 ratio patients with EGFR-mutated (exon 19 deletion or L858R mutation) advanced non-small-cell lung cancer (NSCLC) who had not previously received treatment for advanced disease to receive osimertinib (80 mg once daily) with chemotherapy (pemetrexed [500 mg per square meter of body-surface area] plus either cisplatin [75 mg per square meter] or carboplatin [pharmacologically guided dose]) or to receive osimertinib monotherapy (80 mg once daily). The primary end point was investigator-assessed progression-free survival. Response and safety were also assessed. RESULTS: A total of 557 patients underwent randomization. Investigator-assessed progression-free survival was significantly longer in the osimertinib-chemotherapy group than in the osimertinib group (hazard ratio for disease progression or death, 0.62; 95% confidence interval [CI], 0.49 to 0.79; P<0.001). At 24 months, 57% (95% CI, 50 to 63) of the patients in the osimertinib-chemotherapy group and 41% (95% CI, 35 to 47) of those in the osimertinib group were alive and progression-free. Progression-free survival as assessed according to blinded independent central review was consistent with the primary analysis (hazard ratio, 0.62; 95% CI, 0.48 to 0.80). An objective (complete or partial) response was observed in 83% of the patients in the osimertinib-chemotherapy group and in 76% of those in the osimertinib group; the median response duration was 24.0 months (95% CI, 20.9 to 27.8) and 15.3 months (95% CI, 12.7 to 19.4), respectively. The incidence of grade 3 or higher adverse events from any cause was higher with the combination than with monotherapy - a finding driven by known chemotherapy-related adverse events. The safety profile of osimertinib plus pemetrexed and a platinum-based agent was consistent with the established profiles of the individual agents. CONCLUSIONS: First-line treatment with osimertinib-chemotherapy led to significantly longer progression-free survival than osimertinib monotherapy among patients with EGFR-mutated advanced NSCLC.

OBJECTIVES: In the Phase I/III IMpower133 study, first-line atezolizumab plus carboplatin and etoposide (CP/ET) treatment for extensive-stage small cell lung cancer (ES-SCLC) significantly improved overall survival (OS) and progression-free survival versus placebo plus CP/ET. We explored patient and disease characteristics associated with long-term survival in IMpower133, and associations of differential gene expression and SCLC-A (ASCL1-driven), SCLC-N (NEUROD1-driven), SCLC-P (POU2F3-driven), and SCLC-inflamed (SCLC-I) transcriptional subtypes with long-term survival. MATERIALS AND METHODS: Patients with previously untreated ES-SCLC were randomized 1:1 to four 21-day cycles of CP/ET with atezolizumab or placebo. Long-term survivors (LTS) were defined as patients who lived ≥ 18 months post randomization. A generalized linear model was used to evaluate the odds of living ≥ 18 months. Differential gene expression was analyzed using RNA-sequencing data in LTS and non-LTS. OS was assessed by T-effector and B-cell gene signature expression. Distribution of SCLC transcriptional subtypes was assessed in LTS and non-LTS. RESULTS: More LTS were in the atezolizumab arm (34%) than in the placebo arm (20%). The odds ratio for living ≥ 18 months in the atezolizumab arm versus the placebo arm was 2.1 (P < 0.03). Enhanced immune-related signaling was seen in LTS in both arms. Exploratory OS analyses showed atezolizumab treatment benefit versus placebo across T-effector and B-cell gene signature expression subgroups. A higher proportion of LTS than non-LTS in both arms had the SCLC-I subtype; this difference was particularly pronounced in the atezolizumab arm. CONCLUSION: These exploratory analyses suggest that long-term survival is more likely with atezolizumab than placebo in ES-SCLC, confirming the treatment benefit of the IMpower133 regimen.

BACKGROUND: Osimertinib was first approved for the treatment of non-small cell lung cancer (NSCLC) in patients who have developed the epidermal growth factor receptor (EGFR) T790M mutation after treatment with EGFR tyrosine kinase inhibitors (TKIs). We routinely evaluated the plasma of NSCLC patients with the T790M mutation to more rapidly detect an increase in disease activity and resistance to treatment. METHODS: Eligible patients received osimertinib after resistance to the first- or second-generation of EGFR-TKIs in NSCLC harboring T790M mutation detectable in tumor tissue or plasma. Plasma samples were collected every 8 weeks during osimertinib treatment. The plasma analysis was performed using an improved PNA-LNA PCR clamp method. We tested samples for a resistance mechanism, including EGFR-activating, T790M, and C797S mutations, and assessed the association between the mutations and osimertinib treatment. RESULTS: Of the 60 patients enrolled in the study, 58 were eligible for this analysis. In plasma collected before osimertinib treatment, activating mutations were detected in 47 of 58 patients (81.0%) and T790M was detected in 44 patients (75.9%). Activating mutations were cleared in 60.9% (28/46) and T790M was cleared in 93.0% (40/43). Of these, 71.4% (20/28) of activating mutations and 87.5% (35/40) of T790M mutation were cleared within 8 weeks of treatment. The total response rate (RR) was 53.4% (31/58). The median duration of treatment was 259 days, with a trend toward longer treatment duration in patients who experienced the clearance of activating mutations with osimertinib. At the time of disease progression during osimertinib treatment, C797S was detected in 3 of 37 patients (8.1%). CONCLUSION: Plasma EGFR mutation analysis was effective in predicting the effect of osimertinib treatment.
RESUMO
BACKGROUND: There is no well-established late-line treatment for advanced nonsquamous non-small cell lung cancer (NSCLC). Therefore, we retrospectively determined the efficacy and safety of platinum rechallenge with paclitaxel-carboplatin and bevacizumab in patients with nonsquamous NSCLC as a late-line therapy in a clinical setting. METHODS: Thirty patients with nonsquamous NSCLC who received paclitaxel-carboplatin with bevacizumab therapy as a late-line treatment at Sendai Kousei Hospital (Miyagi, Japan) between December 2011 and December 2021 were enrolled into the study. The efficacy and safety of this treatment were evaluated. The patients were further categorized into responders and nonresponders, and predictive factors of treatment response were estimated. RESULTS: The median progression-free survival (PFS) was 6.3 (range, 4.9-6.8) months, and the median overall survival (OS) was 11.8 (range, 7.2-17.2) months. There were no significant differences in PFS and OS between patients with and those without epidermal growth factor receptor mutations. In the univariate analyses of this study, responders were younger than nonresponders (p = 0.012). No fatal adverse events were reported. CONCLUSIONS: With the increase in the number of treatment options in recent years, the sequence of treatments and overall therapeutic strategy are becoming increasingly important. Thus, platinum rechallenge with paclitaxel-carboplatin and bevacizumab, a late-line treatment for patients with nonsquamous NSCLC, may be an effective therapeutic option.

Importance: Administration of durvalumab after concurrent chemoradiotherapy is the standard treatment of unresectable, locally advanced non-small cell lung cancer (NSCLC); however, 20% to 30% of patients do not receive durvalumab because of adverse events (AEs) during concurrent chemoradiotherapy. In addition, radiotherapy and immunotherapy have a synergistic effect. Objective: To investigate the efficacy and safety of durvalumab immunotherapy plus concurrent radiotherapy followed by maintenance with durvalumab therapy for treatment of locally advanced NSCLC without chemotherapy. Design, Setting, and Participants: The multicenter, single-arm DOLPHIN (Phase II Study of Durvalumab [MEDI4736] Plus Concurrent Radiation Therapy in Advanced Localized NSCLC Patients) nonrandomized controlled trial was performed by 12 institutions in Japan from September 13, 2019, to May 31, 2022. Participants in the primary registration phase included 74 patients with programmed cell death ligand 1 (PD-L1)-positive, unresectable, locally advanced NSCLC. The current analyses were conducted from June 1, 2022, to October 31, 2022. Interventions: Patients received radiotherapy (60 Gy) in combination with concurrent and maintenance durvalumab immunotherapy, 10 mg/kg every 2 weeks, for up to 1 year. Main Outcomes and Measures: The primary end point of the rate of 12-month progression-free survival (PFS), as assessed by an independent central review, was estimated using the Kaplan-Meier method and evaluated with 90% CIs calculated using the Greenwood formula. The key secondary end points were PFS, objective response rate, treatment completion rate, and AEs. Results: Data from 35 patients (median [range] age, 72 [44-83] years; 31 [88.6%] men) were included in the full analysis set of the evaluable population. The 12-month PFS rate was 72.1% (90% CI, 59.1%-85.1%), and the median PFS was 25.6 months (95% CI, 13.1 months to not estimable) at a median follow-up of 22.8 months (range, 4.3-31.8 months). Scheduled radiation therapy was completed in 97.1% of patients. The confirmed objective response rate was 90.9% (95% CI, 75.7%-98.1%), and the treatment completion rate was 57.6% (95% CI, 39.2%-74.5%). Among 34 patients evaluated in the safety analysis set, AEs of grade 3 or 4 occurred in 18 patients (52.9%), and of grade 5 in 2 patients (5.9%). Pneumonitis or radiation pneumonitis of any grade occurred in 23 patients (67.6%), and of grades 3 or 4 in 4 patients (11.8%). Conclusions and Relevance: Findings from this phase 2 nonrandomized controlled trial indicate that durvalumab immunotherapy combined with curative radiotherapy for patients with PD-L1-positive, unresectable, locally advanced NSCLC is a promising treatment with tolerable AEs and is appropriate as a study treatment for phase 3 clinical trials. Trial Registration: Japan Registry of Clinical Trials ID: jRCT2080224763.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.The JIPANG study is an open-label phase III trial evaluating the efficacy of pemetrexed plus cisplatin (PemP) versus vinorelbine plus cisplatin (NP) as adjuvant chemotherapy in patients with stage II-IIIA nonsquamous non-small-cell lung cancer (NSCLC). Here, we report the long follow-up overall survival (OS) data. Eligible patients were randomly assigned to receive either PemP or NP. The primary end point was recurrence-free survival (RFS), and the secondary end point included OS. This analysis was performed using data collected 5 years after the last patient enrollment. Among 804 patients enrolled, 783 patients were eligible (384 for NP and 389 for PemP). The updated median RFS was 37.5 months in the NP arm and 43.4 months in the PemP arm with a hazard ratio of 0.95 (95% CI, 0.79 to 1.14). At a median follow-up of 77.3 months, the OS rates at 3 and 5 years were 84.1% and 75.6% versus 87.0% and 75.0% with a hazard ratio of 1.04 (95% CI, 0.81 to 1.34). This long-term follow-up analysis showed that PemP had similar efficacy to NP in both RFS and OS for this population, with one of the longest OS data compared with the historical data.

BACKGROUND: ONO-4538-52/TASUKI-52 was performed in Japan, Korea, and Taiwan to determine the oncological effectiveness and safety of combining nivolumab or placebo with bevacizumab plus platinum chemotherapy for the initial (first-line) treatment of patients with advanced non-squamous non-small cell lung cancer (nsNSCLC). At the interim analysis (minimum follow-up, 7.4 months), the independent radiology review committee-assessed progression-free survival was significantly longer in the nivolumab arm, but overall survival (OS) data were immature. METHODS: Here, we present the updated OS data. Patients with treatment-naïve stage IIIB/IV or recurrent nsNSCLC without driver mutations in ALK, EGFR, or ROS1, were randomized 1:1 to receive either nivolumab or placebo. Patients in both arms received paclitaxel, carboplatin, and bevacizumab, administered 3-weekly for a maximum of 6 cycles. Nivolumab/placebo and bevacizumab were subsequently continued until disease progression or unacceptable toxicity. RESULTS: Overall, 550 patients were randomized. At the time of the analysis (minimum follow-up: 19.4 months), the median OS was longer in the nivolumab arm than in the placebo arm (30.8 vs. 24.7 months; hazard ratio 0.74, 95% confidence interval 0.58-0.94). The 12-month OS rates were 81.3% vs. 76.3% in the nivolumab vs. placebo arms, respectively. The respective 18-month OS rates were 69.0% vs. 61.9%. CONCLUSION: Nivolumab plus platinum chemotherapy and bevacizumab demonstrated longer OS vs. the placebo combination. We believe this regimen is viable as a standard, first-line treatment for patients with advanced nsNSCLC without driver mutations in ALK, EGFR, or ROS1.

BACKGROUND: This phase II trial was designed to evaluate the efficacy and safety of S-1 combined with weekly irinotecan as a second- or third-line treatment for patients with advanced or recurrent squamous cell lung cancer. METHODS: Patients with a body surface area <1.25, 1.25-1.50, and >1.50 m2 received oral S-1 on days 1-14 at 80, 100, and 120 mg/day, respectively, and irinotecan on days 1 and 8 at 70 mg/m2 every 3 weeks. The primary endpoint was the overall response rate, and the secondary endpoints were progression-free survival, overall survival, and the incidence and severity of adverse effects. RESULTS: Between September 2011 and December 2014, 30 patients were enrolled in this study. The overall response rate was 6.7% (95% confidence interval [CI]: 0.8%-22.1%), and the disease control rate was 73.3%. The median progression-free survival was 3.0 months (95% CI: 2.5-3.4 months), and the median overall survival was 10.5 months (95% CI: 5.6-13.7 months). Grade 3/4 treatment-related adverse events were reported in ≥10% of the patients, including leukopenia (21%), neutropenia (21%), anemia (17%), anorexia (10%), and hypokalemia (10%). CONCLUSIONS: Although the treatment-related adverse events were manageable, the combination of weekly irinotecan and S-1 did not have the expected effect.
