CheckMate 451, a double-blind phase III trial, evaluated nivolumab plus ipilimumab and nivolumab monotherapy as maintenance therapy following first-line chemotherapy for ED-SCLC. METHODS Patients with ED-SCLC, Eastern Cooperative Oncology Group performance status 0-1, and no progression after ≤ 4 cycles of first-line chemotherapy were randomly assigned (1:1:1) to nivolumab 1 mg/kg plus ipilimumab 3 mg/kg once every 3 weeks for 12 weeks followed by nivolumab 240 mg once every 2 weeks, nivolumab 240 mg once every 2 weeks, or placebo for ≤ 2 years or until progression or unacceptable toxicity. Primary end point was overall survival (OS) with nivolumab plus ipilimumab versus placebo. Secondary end points were hierarchically tested. RESULTS Overall, 834 patients were randomly assigned. The minimum follow-up was 8.9 months. OS was not significantly prolonged with nivolumab plus ipilimumab versus placebo (hazard ratio [HR], 0.92; 95% CI, 0.75 to 1.12; P = .37; median, 9.2 v 9.6 months). The HR for OS with nivolumab versus placebo was 0.84 (95% CI, 0.69 to 1.02); the median OS for nivolumab was 10.4 months. Progression-free survival HRs versus placebo were 0.72 for nivolumab plus ipilimumab (95% CI, 0.60 to 0.87) and 0.67 for nivolumab (95% CI, 0.56 to 0.81). A trend toward OS benefit with nivolumab plus ipilimumab was observed in patients with tumor mutational burden ≥ 13 mutations per megabase. Rates of grade 3-4 treatment-related adverse events were nivolumab plus ipilimumab (52.2%), nivolumab (11.5%), and placebo (8.4%). CONCLUSION Maintenance therapy with nivolumab plus ipilimumab did not prolong OS for patients with ED-SCLC who did not progress on first-line chemotherapy. There were no new safety signals

Patients and Methods This was a parallel-cohort phase II study of 105 mg/m2 prexasertib once every 14 days for patients who progressed after no more than two prior therapies and had platinum-sensitive (Cohort 1) or platinum-resistant/platinum-refractory (Cohort 2) disease. The primary endpoint was objective response rate (ORR). Secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), safety, and pharmacokinetics. Exploratory endpoints included biomarker identification and assessment of an alternative regimen (Cohort 3: 40 mg/m2 days 1-3, 14-day cycle). Results In Cohort 1 (n = 58), ORR was 5.2%; DCR, 31%; median PFS, 1.41 months (95% confidence interval [CI], 1.31-1.64); and median OS, 5.42 months (95% CI, 3.75-8.51). In Cohort 2 (n = 60), ORR was 0%; DCR, 20%; median PFS, 1.36 months (95% CI, 1.25-1.45); and median OS, 3.15 months (95% CI, 2.27-5.52). The most frequent all-grade, related, treatment-emergent adverse events were decreased neutrophil count (Cohort 1, 69.6%; Cohort 2, 73.3%), decreased platelet count (Cohort 1, 51.8%; Cohort 2, 50.0%), decreased white blood cell count (Cohort 1, 28.6%; Cohort 2, 40.0%), and anemia (Cohort 1, 39.3%; Cohort 2, 28.3%). Eleven patients (19.6%) in Cohort 1 and one patient (1.7%) in Cohort 2 experienced grade ≥3 febrile neutropenia. Prexasertib pharmacokinetics were consistent with prior studies. Cohort 3 outcomes were similar to those of Cohorts 1 and 2. No actionable biomarkers were identified. Conclusion Prexasertib did not demonstrate activity to warrant future development as monotherapy in ED-SCLC.This research was funded by Eli Lilly and Company

Prognostic Value of Clinical Staging According to TNM in Patients With SCLC: A Real-World Surveillance Epidemiology and End-Results Database Analysis

Long-term survival; Prognostic factor; Small-cell lung cancerSupervivencia a largo plazo: Factor pronóstico; Cáncer de pulmón de células pequeñasSupervivència a llarg termini; Factor pronòstic; Càncer de pulmó de cèl·lules petitesIntroduction SCLC is one of the most lethal malignancies. Classically, staging has been performed using a dual classification distinguishing limited from the extensive stage. This study aimed to evaluate the prognostic value of TNM staging in a real-world population of patients with SCLC. Methods Patients were selected from the Surveillance Epidemiology and End Results database. Chi-square bivariate analysis was used for the association of binary qualitative variables. A multivariate Cox regression analysis was performed to determine the impact of these prognostic factors on median overall survival (mOS) and long-term survival. Results A total of 26,221 patients were included (50.7% men, 55.7% ≥65 y, 82% White). At diagnosis, 18,574 (70.83%) presented metastases, which were more frequent in the liver (n = 11,896, 64%). In the overall population, mOS was 8 (7.86–8.14) months, which decreased according to each increasing category of TNM staging (p < 0.0001). The worse mOS was found among patients with stage IV SCLC (6 mo, 95% confidence interval: 5.83–6.17). Long-term survival decreased according to TNM staging, with patients having stage IV SCLC exhibiting the lowest survival rates at all follow-up time points. Within stage IV, the lowest mOS values were found in patients greater than or equal to 65 years and in those with liver metastases. Among the TNM stages corresponding to the limited stage, stage IB revealed the lowest hazard ratios value for risk of death compared with stage IA (hazard ratio = 1.161, 95% confidence interval: 0.97–1.40, p = 0.114), which increased gradually within the limited-stage SCLC. In the multivariate analysis, TNM staging, male sex, and older age resulted in poor prognostic factors for survival. Conclusions TNM staging seems to define prognosis in patients with SCLC in the real-world setting, particularly for those patients with earlier disease.This study was sponsored by Roche Farma S.A., Spain

Phase Ib/II study of ceritinib in combination with ribociclib in patients with ALK-rearranged non–small cell lung cancer

ALK inhibitors; Ceritinib; RibociclibInhibidores de ALK; Ceritinib; RibociclibInhibidors d'ALK; Ceritinib; RibociclibBackground Preclinical data show that the combination of an ALK inhibitor (ALKi) with a cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) may act synergistically to overcome drug resistance mechanisms. Here, we assessed the safety, tolerability, and preliminary clinical activity of ceritinib, an ALKi in combination with ribociclib, a CDK4/6i, in patients with ALK-rearranged non–small cell lung cancer (NSCLC). Methods This was a multicenter, open-label, phase Ib/II dose-escalation study to determine the maximum tolerated dose (MTD) and/or recommended phase II dose (RP2D) for ceritinib plus ribociclib therapy. Results Twenty-seven adult patients with ALK-rearranged advanced NSCLC with an ECOG PS ≤ 2 were enrolled into five cohorts to receive various dose combinations of ceritinib (range, 300–450 mg/day) and ribociclib (range, 100–300 mg/day). Median age of patients was 57 years. MTDs were not reached in this study. Enrollment into phase Ib was terminated early and phase II was not opened due to changes in the ALK-rearranged NSCLC treatment landscape. Ceritinib 300 mg/day and ribociclib 200 mg/day (3-weeks-on/1-week-off schedule) was identified as the RP2D. Among the 27 evaluable patients, the overall response rate (ORR) was 37.0% (95% CI, 19.4–57.6) and median progression-free survival (mPFS) was 21.5 months (95% CI, 5.5–25.0). At RP2D, the ORR was 50.0%, disease control rate was 75%, and mPFS was 24.8 months (95% CI, 5.5–25.1). Safety profile of the combination therapy was consistent with single-agent safety data. Conclusion Combination of ceritinib and ribociclib showed clinical activity with a manageable safety profile in patients with advanced ALK-rearranged NSCLC.This study was supported by Novartis Pharmaceuticals Corporation

Interrelations between Patients’ Clinicopathological Characteristics and Their Association with Response to Immunotherapy in a Real-World Cohort of NSCLC Patients

Biomarcadores; Eventos adversos relacionados con el sistema inmunitario; InmunoterapiaBiomarcadors; Esdeveniments adversos relacionats amb el sistema immunitari; ImmunoteràpiaBiomarkers; Immune related adverse events; ImmunotherapyImmune checkpoint inhibitors (ICIs) have transformed non-small cell lung cancer (NSCLC) treatment. Unfortunately, only some patients benefit from these therapies. Thus, certain clinicopathological characteristics of the patients have been proposed as biomarkers of ICIs response. We assembled a retrospective cohort of 262 NSCLC patients treated with ICIs, compiled relevant clinicopathological characteristics, and studied their associations with treatment outcome using Cox proportional-hazards survival models. Additionally, we investigated the interrelations between clinicopathological features and devised a method to create a compendium associated with ICIs response by selecting those that provide non-redundant information. In multivariate analyses, ECOG performance status (hazard ratio (HR) 1.37 (95% CI 1.11 to 1.68), p < 0.005), LDH (HR 1.24 (95% CI 1.03 to 1.48), p = 0.02)) and PD-L1 negativity were associated with decreased progression-free survival (PFS) (HR 1.92 (95% CI 1.03 to 3.58), p = 0.04), whereas presentation of immune-related adverse events (irAEs) (HR 0.35 (95% CI 0.22 to 0.55, p < 0.005) or females (HR 0.52 (95% CI 0.33 to 0.80, p < 0.005) had longer PFS. Additionally, numerous clinicopathological indicators were found to be interrelated. Thus, we searched for features that provide non-redundant information, and found the combination of LDH levels, irAEs, and gender to have a better association with ICIs treatment response (cross-validated c-index = 0.66). We concluded that several clinicopathological features showed prognostic value in our real-world cohort. However, some are interrelated, and compendiums of features should therefore consider these interactions. Joint assessment of LDH, irAEs, and gender may be a good prognostic compendium.None associated with this project

High levels of chromosomal aberrations negatively associate with benefit to checkpoint inhibition in NSCLC

Immunotherapy; Lung neoplasms; Tumor biomarkersImmunoteràpia; Càncer de pulmó; Biomarcadors tumoralsInmunoterapia; Cáncer de pulmón; Biomarcadores tumoralesBackground Immune checkpoint inhibitors (ICIs) targeting the programmed cell death 1/programmed death-ligand 1 axis have transformed the management of advanced non-small cell lung cancer (NSCLC). However, many patients do not benefit from this type of treatment, and thus several molecular biomarkers of benefit have been explored. The value of somatic copy number alterations (SCNAs) burden remains elusive. Patients and methods We assembled a cohort of 109 patients with NSCLC treated with ICIs and available tumor samples. We performed shallow whole-genome sequencing on 89 patients to determine genome-wide SCNAs and targeted gene expression analysis on 63 patients to study immune infiltration. We analyzed SCNAs burden in different ways (ie, the fraction of the genome altered or number of events) and studied their association with ICIs benefit based on survival analysis. We correlated SCNAs burden and immune infiltration on 35 patients of our cohort and on patients with lung adenocarcinoma from The Cancer Genome Atlas (TCGA). Results High SCNAs burden, computed in diverse ways, is negatively associated with ICIs progression-free survival (PFS), with the fraction of the genome altered (FGA) by arm and chromosome events showing the strongest association with PFS (p=0.002) (n=77). Nevertheless, we found differences in SCNAs across some clinicopathological features (sample site origin). A multivariate analysis adjusted for relevant characteristics showed that the FGA of arm and chromosome alterations was strongly associated with PFS (HR=2.21, p=3.3 x 10−5). Finally, we confirmed that SCNAs burden negatively correlates with tumor immune infiltration (n=35), although this correlation was not found for the males studied. Similar results were observed in the TCGA cohort. Conclusions SCNAs burden is a potential biomarker of benefit to ICIs in patients with NSCLC, although there appear to be some nuances worth consideration. Further studies will be needed to establish its role as a biomarker of benefit to ICIs.This work was supported by Merck Healthcare KGaA, Darmstadt, Germany (Grant for Oncology Innovation to the Vall d’Hebron Institute of Oncology (VHIO), Barcelona, Spain), Fundación Cientifica Asociación Española Contra el Cancer-AECC (grant number GCB14142170 to EF); the Catalan Government/AGAUR (2017–SGR–1738 to EF).

Overview of Checkpoint Inhibitors Mechanism of Action: Role of Immune-Related Adverse Events and Their Treatment on Progression of Underlying Cancer

Corticosteroids; Efficacy; Immune checkpoint inhibitorsCorticosteroides; Eficacia; Inhibidores del punto de control inmunitarioCorticoides; Eficàcia; Inhibidors del punt de control immunitariIn recent years, immunotherapy-based regimens have been included into the treatment's algorithm of several cancer types. Programmed death-1 (PD-1) and cytotoxic T lymphocyte antigen-4 (CTLA-4) interact with their ligands found on the surface of antigen presenting cells (APC) or tumor cells (PD-L1/2 and CD80/86). Through these interactions, stimulatory or inhibitory signals are established. Immune checkpoint inhibitors (ICIs), block these interactions, and when administered not only as monotherapy but also as part of combination regimens, have shown to improve survival results in multiple advanced cancers leading to an increasing number of patients treated with ICI and, as a consequence, a rise in the number of patients developing immune-related adverse events (irAEs). Presence of irAEs has been associated with greater benefit from treatment, especially when blocking PD-L1. Recent data suggests that treatment benefit persists after discontinuation of ICIs due to a treatment related adverse event, regardless of the grade. Patients experiencing grade 3-4 irAEs are at risk of toxicity recurrence after reintroducing immunotherapy and therefore, the decision to resume the treatment is challenging. In these cases, a multidisciplinary approach is always needed and several factors should be considered. Management of severe toxicities may require systemic corticosteroids which can impact on T-cell function. Due to their immunosuppressive properties, it is necessary to deeper determine how corticosteroids influence responses. In terms of overall survival (OS), the use of steroids as therapy for irAEs seems not to reduce OS and several studies have reported durable responses in patients experiencing autoimmune toxicities treated with corticosteroids

Efficacy of chemotherapy for malignant pleural mesothelioma according to histology in a real-world cohort

Cancer therapy; MesotheliomaTerapia del cáncer; MesoteliomaTeràpia del càncer; MesoteliomaCheckMate 743 trial demonstrated survival benefit of immunotherapy in first line in MPM with some differences in the efficacy of chemotherapy according to histology. The objective of this study is to characterize the impact of chemotherapy according to histology in patients diagnosed with MPM at our institution. Clinical records of all MPM patients diagnosed at Vall d’Hebron University Hospital between November 2002 and April 2020 were reviewed. Associations between clinical variables and outcomes were assessed with Cox regression models. Survival data were calculated by the Kaplan–Meier method. 189 patients were included with 76% of tumors classified as epithelioid subtype. First line chemotherapy was offered to 85% of patients. Median survival in overall population was 21.3 months (95% CI 17.2–24.3). We found that patients with epithelioid tumors had better overall survival (OS) and progression free survival (PFS). Median OS of epithelioid patients treated with first line chemotherapy was 26.7 months versus 15.0 months in non-epithelioid patients (HR 2.25 CI 95% 1.4–3.4; p < 0.001). Median PFS for patients with epithelioid tumors treated with chemotherapy was 4.8 months versus 3.6 months in non-epithelioid (HR 1.5 CI 95% 1.0–2.3; p = 0.03). The improvement of outcomes in patients with epithelioid histology was detected in patients treated with cisplatin or carboplatin. Histology was not a predictive factor for the platinum agent sensitivity (p of interaction PFS = 0.09, p of interaction OS = 0.65). In our series, patients with non-epithelioid tumors presented worse prognosis. Although epithelioid tumors exposed to cisplatin had higher PFS, histology was not a clear predictor of chemotherapy efficacy

RESILIENT Part 2: A Randomized, Open-Label Phase III Study of Liposomal Irinotecan Versus Topotecan in Adults With Relapsed Small Cell Lung Cancer

PURPOSE The phase III RESILIENT trial compared second-line liposomal irinotecan with topotecan in patients with small cell lung cancer (SCLC). PATIENTS AND METHODS Patients with SCLC and progression on or after first-line platinum-based chemotherapy were randomly assigned (1:1) to intravenous (IV) liposomal irinotecan (70 mg/m(2) every 2 weeks in a 6-week cycle) or IV topotecan (1.5 mg/m(2) daily for 5 consecutive days, every 3 weeks in a 6-week cycle). The primary end point was overall survival (OS). Key secondary end points included progression-free survival (PFS) and objective response rate (ORR). RESULTS Among 461 randomly assigned patients, 229 received liposomal irinotecan and 232 received topotecan. The median follow-up was 18.4 months. The median OS was 7.9 months with liposomal irinotecan versus 8.3 months with topotecan (hazard ratio [HR], 1.11 [95% CI, 0.90 to 1.37]; P = .31). The median PFS per blinded independent central review (BICR) was 4.0 months with liposomal irinotecan and 3.3 months with topotecan (HR, 0.96 [95% CI, 0.77 to 1.20]; nominal P = .71); ORR per BICR was 44.1% (95% CI, 37.6 to 50.8) and 21.6% (16.4 to 27.4), respectively. Overall, 42.0% and 83.4% of patients receiving liposomal irinotecan and topotecan, respectively, experienced grade >= 3 related treatment-emergent adverse events (TEAEs). The most common grade >= 3 related TEAEs were diarrhea (13.7%), neutropenia (8.0%), and decreased neutrophil count (4.4%) with liposomal irinotecan and neutropenia (51.6%), anemia (30.9%), and leukopenia (29.1%) with topotecan. CONCLUSION Liposomal irinotecan and topotecan demonstrated similar median OS and PFS in patients with relapsed SCLC. Although the primary end point of OS was not met, liposomal irinotecan demonstrated a higher ORR than topotecan. The safety profile of liposomal irinotecan was consistent with its known safety profile; no new safety concerns emerged
