Durvalumab after Chemoradiotherapy in Limited-Stage Small-Cell Lung Cancer.

Background: Adjuvant therapy with durvalumab, with or without tremelimumab, may have efficacy in patients with limited-stage small-cell lung cancer who do not have disease progression after standard concurrent platinum-based chemoradiotherapy.

Methods: In a phase 3, double-blind, randomized, placebo-controlled trial, we assigned patients to receive durvalumab at a dose of 1500 mg, durvalumab (1500 mg) plus tremelimumab at a dose of 75 mg (four doses only), or placebo every 4 weeks for up to 24 months. Randomization was stratified according to disease stage (I or II vs.

The Utility and Limitations of Universal Polymerase Chain Reaction Screening for SARS-CoV-2 During Hospital Admission.

Objective: Universal polymerase chain reaction (PCR) screening for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on hospital admission is an effective approach to preventing coronavirus disease 2019 (COVID-19) outbreaks in medical facilities. However, false-positive test results due to a recent infection are a concern. We investigated the usefulness and limitations of universal PCR screening for SARS-CoV-2 on hospital admission in a real-world setting.

Osimertinib readministration for central nervous system metastases in non-small cell lung cancer positive for EGFR activating mutations.

Background: Osimertinib shows pronounced efficacy for EGFR mutation-positive non-small cell lung cancer (NSCLC) including associated central nervous system (CNS) metastases. Tumors inevitably develop resistance to the drug, however. Osimertinib is sometimes readministered after completion of standard chemotherapy.

Effectiveness and Safety of Immune Checkpoint Inhibitors Alone or in Combination With Chemotherapy in Pulmonary Sarcomatoid Carcinoma.

Introduction: Pulmonary sarcomatoid carcinoma (PSC) is a rare subtype of lung cancer associated with poor prognosis and resistance to conventional chemotherapy. Immune checkpoint inhibitors (ICIs), alone or in combination with chemotherapy, were found to have clinical benefits in PSC in recent studies. Nevertheless, because these studies included a small number of patients owing to disease rarity, larger studies are needed to evaluate the effectiveness and safety of ICI-based therapy for PSC.

Five Cases of Cytokine Release Syndrome in Patients Receiving Cytotoxic Chemotherapy Together With Nivolumab Plus Ipilimumab: A Case Report.

We conducted a phase 3 clinical trial to compare the efficacy of platinum-based combination chemotherapy together with nivolumab plus ipilimumab relative to that of platinum-based combination chemotherapy together with pembrolizumab in previously untreated patients with advanced NSCLC. The trial was terminated prematurely after treatment of 295 patients because of a high proportion of treatment-related deaths, three of which were due to cytokine release syndrome (CRS), in the nivolumab plus ipilimumab treatment arm. In addition, we encountered two cases of CRS that were effectively managed, for a total of five cases (3.

Acute myeloid leukemia and myelodysplastic syndrome associated with a combination of immune checkpoint inhibitor and platinum-based chemotherapy.

Therapy related-acute myeloid leukemia (t-AML) and myelodysplastic syndrome (t-MDS) are complications of chemotherapy and/or radiation therapy for malignant diseases. In this report, we describe a patient with advanced lung adenocarcinoma who developed autoimmune hemolytic anemia and MDS associated with a combination of atezolizumab and platinum-based chemotherapy. The patient showed progression from t-MDS to t-AML 20 months after the treatment was initiated.

Impact of increased plasma levels of calreticulin on prognosis of patients with advanced lung cancer undergoing combination treatment of chemotherapy and immune checkpoint inhibitors.

Background: Damage-associated molecular pattern (DAMP)-related immunogenic cell death triggers secondary adaptive immune responses. The relationship between DAMP levels and prognosis in patients with non-small cell lung cancer (NSCLC) who undergo a combination therapy of immune checkpoint inhibitors (ICI) and chemotherapy remains unclear.

Methods: Serial plasma samples were prospectively collected from 45 patients treated with ICI combination therapy for advanced NSCLC.

Impact of the pretreatment prognostic nutritional index on the survival after first-line immunotherapy in non-small-cell lung cancer patients.

Background: Immunotherapy has become a standard-of-care for patients with non-small-cell lung cancer (NSCLC). Although several biomarkers, such as programmed cell death-1, have been shown to be useful in selecting patients likely to benefit from immune checkpoint inhibitors (ICIs), more useful and reliable ones should be investigated. The prognostic nutritional index (PNI) is a marker of the immune and nutritional status of the host, and is derived from serum albumin level and peripheral lymphocyte count.

Phase 1 study of DS-1205c combined with gefitinib for EGFR mutation-positive non-small cell lung cancer.

Background: Tyrosine kinase inhibitors (TKIs) are effective for the treatment of non-small cell lung cancer (NSCLC) patients with activating mutations of the epidermal growth factor receptor (EGFR), but responses are not durable as tumors develop resistance. DS-1205c is a novel, specific, orally bioavailable, small-molecule AXL receptor TKI. In preclinical studies, DS-1205c restored TKI antitumor activity in a TKI acquired-resistance EGFR-mutant NSCLC tumor xenograft model.

Forthcoming Phase II Study of Durvalumab (MEDI4736) Plus Chemotherapy for Small Cell Lung Cancer with Brain Metastases.

Background: The standard of care for extensive-stage small cell lung cancer (ES-SCLC) is an immune checkpoint inhibitor (ICI) combined with platinum-etoposide (PE) chemotherapy. At initial diagnosis, about 25% of ES-SCLC patients have brain metastases, which are associated with a poor prognosis. The decision as to whether to treat brain metastases with local therapies such as surgery or radiotherapy before initiation of systemic chemoimmunotherapy is based on symptoms due to the brain lesions and the general condition of the patient.

Association of thyroid transcription factor-1 (TTF-1) expression with efficacy of PD-1/PD-L1 inhibitors plus pemetrexed and platinum chemotherapy in advanced non-squamous non-small cell lung cancer.

Background: Thyroid transcription factor-1 (TTF-1) expression in advanced non-squamous non-small cell lung cancer (NSCLC) has been associated with the efficacy of pemetrexed plus platinum chemotherapy. However, the relation between TTF-1 expression and efficacy of the combination of programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) inhibitors plus pemetrexed and platinum chemotherapy, a standard first-line treatment regimen for advanced non-squamous NSCLC, has remained unclear.

Methods: We retrospectively evaluated TTF-1 expression in tumor tissue of patients with advanced or recurrent non-squamous NSCLC treated with PD-1/PD-L1 inhibitors plus pemetrexed and platinum chemotherapy in the first-line setting.

Phase II study of carboplatin/nab-paclitaxel/atezolizumab combination therapy for advanced nonsquamous non-small cell lung cancer patients with impaired renal function: RESTART trial.

Background:  First-line treatment of nonsquamous non-small cell lung cancer (NSCLC) has undergone a paradigm shift to platinum combination therapy together with immune checkpoint inhibitors (ICIs). However, phase III studies of combinations of cytotoxic chemotherapy and ICIs have included only patients with maintained organ function, not those with renal impairment.

Methods: Cytotoxic chemotherapy-naïve advanced nonsquamous NSCLC patients aged 20 years or older with impaired renal function (creatinine clearance of 15 to 45 mL/min) are prospectively registered in this single-arm phase II study and receive combination therapy with carboplatin, nanoparticle albumin-bound (nab-) paclitaxel, and atezolizumab.

A Randomized Comparison of Nivolumab versus Nivolumab + Docetaxel for Previously Treated Advanced or Recurrent ICI-Naïve Non-Small Cell Lung Cancer: TORG1630.

Purpose: The addition of cytotoxic chemotherapy to immune-checkpoint inhibitor (ICI) may enhance antitumor effects. We conducted an open-label randomized phase II/III study to evaluate nivolumab + docetaxel combination therapy in comparison with nivolumab monotherapy for previously treated ICI-naïve non-small cell lung cancer (NSCLC).

Patients And Methods: The primary endpoint of the phase III study was overall survival (OS), and the secondary endpoints included progression-free survival (PFS), overall response rate (ORR), and toxicity.

Nivolumab Retreatment in Non-Small Cell Lung Cancer Patients Who Responded to Prior Immune Checkpoint Inhibitors and Had ICI-Free Intervals (WJOG9616L).

Purpose: To explore the efficacy of retreatment with immune checkpoint inhibitors (ICI) in patients with advanced non-small cell lung cancer (NSCLC) who responded to prior ICI and had adequate ICI-free interval.

Patients And Methods: Patients with advanced NSCLC who had achieved complete response (CR), partial response (PR), or stable disease for ≥6 months with prior ICI therapy preceding progression were prospectively enrolled. All patients should have had ICI-free interval ≥60 days before registration.

Exploratory Analysis Comparing Fosnetupitant Versus Fosaprepitant for Prevention of Highly Emetogenic Chemotherapy-Induced Nausea and Vomiting (CINV): A Randomized, Double-Blind, Phase 3 Study (CONSOLE).

Introduction: We describe the results of an exploratory analysis performed on the first head-to-head study (JapicCTI-194611) comparing two different intravenous (IV) neurokinin 1 (NK) receptor antagonists, fosnetupitant and fosaprepitant, in combination with palonosetron (PALO) and dexamethasone (DEX) for the prevention of highly emetogenic chemotherapy (HEC)-induced nausea and vomiting (CINV). This analysis was performed to validate the findings of the primary analysis (previously published) utilizing a last observation carried forward (LOCF) approach for missing values for the efficacy endpoint of complete response (no emetic event and no rescue medication), while also evaluating the time periods encompassing the 0-168-hour (h) "extended overall phase" interval.

Methods: Patients scheduled to receive cisplatin-based chemotherapy were randomized 1:1 to fosnetupitant 235 mg or fosaprepitant 150 mg in combination with PALO 0.

A Multicenter, Randomized Phase III Study Comparing Platinum Combination Chemotherapy Plus Pembrolizumab With Platinum Combination Chemotherapy Plus Nivolumab and Ipilimumab for Treatment-Naive Advanced Non-Small Cell Lung Cancer Without Driver Gene Alterations: JCOG2007 (NIPPON Study).

Background: First-line treatment of non-small cell lung cancer (NSCLC) has undergone a paradigm shift to platinum combination chemotherapy together with an immune checkpoint inhibitor, regardless of the expression level of the programmed cell death-1 (PD-1) ligand PD-L1 on tumor cells. Moreover, such chemotherapy plus nivolumab (antibody to PD-1) and ipilimumab (antibody to cytotoxic T lymphocyte-associated protein-4) prolonged survival in advanced NSCLC patients compared with chemotherapy alone. We have now designed a randomized, controlled phase III trial (NIPPON, JCOG2007) to confirm that platinum combination chemotherapy plus nivolumab and ipilimumab is superior to such chemotherapy plus pembrolizumab (antibody to PD-1) for treatment-naive patients with advanced NSCLC.
