RESUMO
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.

Osimertinib is the standard of care for patients with epidermal growth factor receptor-activating mutation-positive non-small cell lung cancer. Dose-toxicity has been previously reported, but no dose-response data within the range of 20-240 mg daily (mg/d). Thus, the current 80 mg/d dosing might be too high for elderly Japanese patients with an average body weight of only 50 kg, resulting in excessive toxicity and cost. We therefore initiated a study to investigate whether osimertinib at 40 mg/d is non-inferior to 80 mg/d in patients with advanced or recurrent epidermal growth factor receptor-activating mutation-positive non-small cell lung cancer aged ≥70 years, using a regression discontinuity design. Osimertinib is administered at 40 mg/d for body weight ≤50 kg, and 80 mg/d for body weight >50 kg. The primary endpoint is progression-free survival. Sample size is 550 patients, based on a non-inferiority margin of the progression-free survival hazard ratio 1.333, 0.10 one-sided type I error and 80% power.

To understand the relationship between the radioactive cesium (Cs) concentration in muscle of Japanese flounder Paralichthys olivaceus and the species' biological characteristics (size, sex, and age) under conditions of ecological equilibrium (i.e., distributed among ecosystem components over sufficient time, and with nearly constant ratios of Cs concentration in organisms to the concentration in water) as existed before the accident at the Fukushima Dai-ichi Nuclear Power Station (FDNPS), Japan, in 2011, we examined stable Cs, as it is thought to exist in equilibrium in the environment and behave similarly to radioactive Cs in aquatic animals. The concentration of stable Cs in 241 P. olivaceus (range 216-782 mm total length [TL]) collected in Sendai Bay, approximately 90 km north of the FDNPS, in June-July 2015 was expressed as an exponential function with size as an independent variable; the results show the concentration of stable Cs doubled with an increase in TL of 442 mm. Next, to evaluate the cause of the size-dependent change in stable Cs concentration, we examined 909 individuals (200-770 mm TL) collected in September 2013-July 2015 to determine their feeding habit based on size. Analysis of the frequency of occurrence of prey organisms in stomach contents showed that sand lance Ammodytes japonicus (55-180 mm standard length [SL]) was the most consistently consumed across size classes. Analysis on a wet-mass basis showed that A. japonicus and anchovy Engraulis japonicus (65-130 mm SL) were the main food of P. olivaceus sized 200-599 mm TL, whereas chub mackerel Scomber japonicus (120-230 mm SL) and two species of flatfishes (180-205 mm SL) were abundant in the diet of P. olivaceus sized ≥600 mm TL. All these prey items were presumed to have similar concentrations of stable Cs. Based on the above, the effect of diet on the relationship between stable Cs in muscle and fish size was considered negligible. That the diet of P. olivaceus largely did not change with size was also confirmed by C and N stable isotope ratios in P. olivaceus and their prey species. Therefore, the Cs-size relationship is probably determined by changes in the balance between the rate of Cs intake from food and seawater and the excretion rate during growth, both of which change as functions of body mass. Values of stable Cs concentrations among environmental components and animals appear to be a valid indicator for understanding the radioactive Cs distribution in the marine environment and aquatic animals under the equilibrium state, as existed before the 2011 nuclear accident.

PURPOSE: The TORG0503 study was undertaken to select a preferred platinum-based third-generation regimen for patients with completely resected non-small cell lung cancer (NSCLC). This study aimed to describe the quality of life (QOL) analysis of that study. METHODS: Patients with completely resected NSCLC were randomized to receive three cycles of docetaxel plus cisplatin (DC) or paclitaxel plus carboplatin (PC) on day 1 every 3 weeks. QOL was assessed at three time points (baseline, after two cycles, and after three cycles) using the Functional Assessment of Cancer Therapy-taxane (FACT-Taxane). The adjusted odds ratio (OR) and 95% confidence interval (CI) were calculated by logistic regression analysis that was adjusted for the baseline score in the FACT-Taxane total score and each subscale to evaluate treatment (PC vs. DC) effectiveness. RESULTS: QOL data from 104 patients (DC, n = 56 patients; PC, n = 48) were analyzed. In the FACT-Taxane total score, the baseline-adjusted OR (95% CI) of not worse QOL for the DC group was 3.3 (1.4-8.3) compared with the PC group. In the taxane subscale, the baseline-adjusted OR (95% CI) was 6.2 (2.6-16.0). CONCLUSION: Total QOL was maintained better in the DC group than in the PC group, especially the taxane subscale that consists of neurotoxicity and taxane components in spite of no treatment-related death in both arms between DC and PC. We might recommend DC as the control regimen for the next clinical trial from the viewpoint of QOL, similar to the primary outcomes in TORG0503.

BACKGROUND: Amrubicin (AMR) is one of the most active agents for small-cell lung cancer (SCLC). However, hematologic toxicity and infection at a commonly used dose (40 mg/m2) is problematic; the optimal dose remains undetermined. PATIENTS AND METHODS: To evaluate the optimal dose of AMR in terms of efficacy and safety, we reviewed consecutive data on patients with relapsed SCLC who received AMR at doses of 40, 35, and 30 mg/m2 (on days 1-3) at Nippon Medical School Hospital between October 2010 and November 2021. RESULTS: We reviewed the data of 86 patients (20, 45, 27 who received AMR doses of 40, 35, 30 mg/m2, respectively) according to our study criteria. For patients ≥ 75 years, the proportion who received second-line treatment tended to be higher in the 30-35 mg/m2 group. Objective response rates were 37/46/35%, median progression-free survival (PFS) were 3.0/4.7/3.2 months, and median overall survival (OS) were 7.8/16.3/8.0 months, respectively. Grade 4 neutropenia occurred in 58/39/31% of patients, which was higher for the 40 mg/m2 group. The incidence of febrile neutropenia did not differ between groups. Multivariate analysis identified the AMR dose was not associated with longer PFS and OS. CONCLUSION: Treatment with AMR between 30 and 35 mg/m2 showed relatively mild hematologic toxicity compared with AMR at 40 mg/m2, without any significant difference in efficacy. Lower dose of AMR for relapsed SCLC could be a promising treatment option.

Although adjuvant tegafur/uracil (UFT) is recommended for patients with completely resected stage I non-small-cell lung cancer (NSCLC) in Japan, only one-third of cases has received adjuvant chemotherapy (ADJ) according to real-world data. Therefore, robust predictive biomarkers for selecting ADJ or observation (OBS) without ADJ are needed. Patients who underwent complete resection of stage I lung adenocarcinoma with or without adjuvant UFT were enrolled. The status of ACTN4 gene amplification was analyzed by FISH. Statistical analyses to determine whether the status of ACTN4 gene amplification affected recurrence-free survival (RFS) were carried out. Formalin-fixed, paraffin-embedded samples from 1136 lung adenocarcinomas were submitted for analysis of ACTN4 gene amplification. Ninety-nine (8.9%) of 1114 cases were positive for ACTN4 gene amplification. In the subgroup analysis of patients aged 65 years or older, the ADJ group had better RFS than the OBS group in the ACTN4-positive cohort (hazard ratio [HR], 0.084, 95% confidence interval [CI], 0.009-0.806; P = .032). The difference in RFS between the ADJ group and the OBS group was not significant in ACTN4-negative cases (all ages: HR, 1.214; 95% CI, 0.848-1.738; P = .289). Analyses of ACTN4 gene amplification contributed to the decision regarding postoperative ADJ for stage I lung adenocarcinomas, preventing recurrence, improving the quality of medical care, preventing the unnecessary side-effects of ADJ, and saving medical costs.

BACKGROUND: Fosnetupitant (FosNTP), an intravenous neurokinin 1 receptor antagonist, demonstrated a favorable safety profile with a potentially low risk of injection site reactions (ISRs) and promising antiemetic efficacy in patients receiving cisplatin-based highly emetogenic chemotherapy in a previous phase 2 study. We conducted a randomized, double-blind safety study to evaluate the safety profile of FosNTP, including ISRs, in patients receiving doxorubicin-cyclophosphamide or epirubicin-cyclophosphamide (AC/EC) chemotherapy. METHODS: Patients scheduled to receive AC/EC were randomized 1:1 to receive 235 mg of FosNTP or 150 mg of fosaprepitant (FosAPR), both in combination with 0.75 mg of intravenous palonosetron and 9.9 mg of dexamethasone on day 1. The stratification factors were age category (<55 vs ≥55 years) and study site. The primary end point was the incidence of treatment-related adverse events (TRAEs) with FosNTP. RESULTS: Overall, 102 patients were randomized to FosNTP (n = 52) or FosAPR (n = 50), and all were treated with the study drug and evaluated for safety. The primary end point, the incidence of TRAEs, was similar with FosNTP (21.2%; 95% confidence interval [CI], 11.1%-34.7%) and FosAPR (22.0%; 95% CI, 11.5%-36.0%), with any-cause ISRs observed in 5.8% and 26.0% of patients, respectively, and treatment-related ISRs observed in 0% and 10.0%, respectively. The overall (0-120 hour) complete response (defined as no emetic event and no rescue medication) rate, standardized by age category in the full analysis set, was 45.9% (23 of 51 patients) with FosNTP and 51.3% (25 of 49 patients) with FosAPR. CONCLUSIONS: FosNTP demonstrated a favorable safety profile with a very low risk of ISRs in the AC/EC setting.

BACKGROUND: Interstitial pneumonia (IP) is a poor prognostic comorbidity in patients with non-small cell lung cancer (NSCLC) and is also a risk factor for pneumonitis. The TORG1936/AMBITIOUS trial, the first known phase II study of atezolizumab in patients with NSCLC with comorbid IP, was terminated early because of the high incidence of severe pneumonitis. METHODS: This study included patients with idiopathic chronic fibrotic IP, with a predicted forced vital capacity (%FVC) of >70%, with or without honeycomb lung, who had previously been treated for NSCLC. The patients received atezolizumab every 3 weeks. The primary endpoint was the 1-year survival rate. RESULTS: A total of 17 patients were registered; the median %FVC was 85.4%, and 41.2% had honeycomb lungs. The 1-year survival rate was 53.3% (95% CI, 25.9-74.6). The median overall and progression-free survival times were 15.3 months (95% CI, 3.1-not reached) and 3.2 months (95% CI, 1.2-7.4), respectively. The incidence of pneumonitis was 29.4% for all grades, and 23.5% for grade ≥3. Tumor mutational burden and any of the detected somatic mutations were not associated with efficacy or risk of pneumonitis. CONCLUSION: Atezolizumab may be one of the treatment options for patients with NSCLC with comorbid IP, despite the high risk of developing pneumonitis. This clinical trial was retrospectively registered in the Japan Registry of Clinical Trials on August 26, 2019, (registry number: jRCTs031190084, https://jrct.niph.go.jp/en-latest-detail/jRCTs031190084).

Patients with uncommon EGFR-mutated non-small-cell lung cancer (NSCLC) demonstrated lower clinical efficacy of first-generation EGFR-tyrosine kinase inhibitors compared with patients harboring common EGFR-mutated NSCLC. The US FDA has approved afatinib for uncommon EGFR mutation positive NSCLC based on the pooled analysis in the first- or second-line setting. Osimertinib has limited evidence in the small sample sizes of phase 2 studies in any-line settings. The aim of the present single-arm, multicenter, phase 2 study is to evaluate the efficacy of osimertinib for previously untreated NSCLC. The primary end point is to assess the overall response to osimertinib. The secondary end points include disease control rate, progression-free survival, duration of time-to-treatment failure, overall survival and safety. Clinical trial registration: jRCTs071200002.
Lay abstract Tyrosine kinase inhibitor (TKI) medications are targeting EGFR work on the first-line treatment for patients with common EGFR mutation positive non-small-cell lung cancer (EGFR+ NSCLC) that has spread to other parts of the body and has the EGFR+ NSCLC in tumor testing. Uncommon EGFR mutations and compound EGFR mutations have less activity for first-generation EGFR-TKIs; however, second- or third-generation EGFR-TKIs are broader spectrum than first-generation EGFR-TKIs have activities ideally. The authors describe the need for and design a study of osimertinib in patients with uncommon/compound EGFR+ NSCLC.

Idiopathic pulmonary fibrosis (IPF), a progressive disorder of unknown etiology, is characterized by pathological lung fibroblast activation and proliferation resulting in abnormal deposition of extracellular matrix proteins within the lung parenchyma. The pathophysiological roles of exosomal microRNAs in pulmonary fibrosis remain unclear; therefore, we aimed to identify and characterize fibrosis-responsive exosomal microRNAs. We used microRNA array analysis and profiled the expression of exosome-derived miRNA in sera of C57BL/6 mice exhibiting bleomycin-induced pulmonary fibrosis. The effect of microRNAs potentially involved in fibrosis was then evaluated in vivo and in vitro. The expression of exosomal microRNA-16 was increased by up to 8.0-fold on day 14 in bleomycin-treated mice, compared to vehicle-treated mice. MicroRNA-16 mimic administration on day 14 after bleomycin challenge ameliorated pulmonary fibrosis and suppressed lung and serum expression of secreted protein acidic and rich in cysteine (SPARC). Pretreatment of human lung fibroblasts with the microRNA-16 mimic decreased the expression of rapamycin-insensitive companion of mTOR (Rictor) and TGF-ß1-induced expression of SPARC. This is the first study reporting the anti-fibrotic properties of microRNA-16 and demonstrating that these effects occur via the mTORC2 pathway. These findings support that microRNA-16 may be a promising therapeutic target for IPF.

OBJECTIVE: Monitoring quality of life (QoL) in patients with cancer can provide insight into functional, psychological and social consequences associated with illness and its treatment. The primary objective of this study is to examine the influence of cultural factors on the communication between the patient and the health care provider and the perceived QoL in women with breast cancer in Japan and the Netherlands. METHODS: In Japanese and Dutch women with early breast cancer, the number, content and frequency of QoL-related issues discussed at the medical encounter were studied. Patients completed questionnaires regarding QoL and evaluation of communication with the CareNoteBook. RESULTS: The total number, frequency and content of QoL-related issues discussed differed between the two countries. Japanese women (n = 134) were significantly more reticent in discussing QoL-issues than the Dutch women (n = 70) (p < .001). Furthermore, Dutch patients perceived the CareNoteBook methodology significantly more positively than the Japanese patients (p < .001). Both groups supported the regular assessment via a CareNoteBook methodology. CONCLUSIONS: Japanese women are more reluctant in expressing their problems with the illness, its treatment and patient-physician communication than Dutch women.

BACKGROUND: An earlier analysis in this phase 3 trial showed that durvalumab significantly prolonged progression-free survival, as compared with placebo, among patients with stage III, unresectable non-small-cell lung cancer (NSCLC) who did not have disease progression after concurrent chemoradiotherapy. Here we report the results for the second primary end point of overall survival. METHODS: We randomly assigned patients, in a 2:1 ratio, to receive durvalumab intravenously, at a dose of 10 mg per kilogram of body weight, or matching placebo every 2 weeks for up to 12 months. Randomization occurred 1 to 42 days after the patients had received chemoradiotherapy and was stratified according to age, sex, and smoking history. The primary end points were progression-free survival (as assessed by blinded independent central review) and overall survival. Secondary end points included the time to death or distant metastasis, the time to second progression, and safety. RESULTS: Of the 713 patients who underwent randomization, 709 received the assigned intervention (473 patients received durvalumab and 236 received placebo). As of March 22, 2018, the median follow-up was 25.2 months. The 24-month overall survival rate was 66.3% (95% confidence interval [CI], 61.7 to 70.4) in the durvalumab group, as compared with 55.6% (95% CI, 48.9 to 61.8) in the placebo group (two-sided P=0.005). Durvalumab significantly prolonged overall survival, as compared with placebo (stratified hazard ratio for death, 0.68; 99.73% CI, 0.47 to 0.997; P=0.0025). Updated analyses regarding progression-free survival were similar to those previously reported, with a median duration of 17.2 months in the durvalumab group and 5.6 months in the placebo group (stratified hazard ratio for disease progression or death, 0.51; 95% CI, 0.41 to 0.63). The median time to death or distant metastasis was 28.3 months in the durvalumab group and 16.2 months in the placebo group (stratified hazard ratio, 0.53; 95% CI, 0.41 to 0.68). A total of 30.5% of the patients in the durvalumab group and 26.1% of those in the placebo group had grade 3 or 4 adverse events of any cause; 15.4% and 9.8% of the patients, respectively, discontinued the trial regimen because of adverse events. CONCLUSIONS: Durvalumab therapy resulted in significantly longer overall survival than placebo. No new safety signals were identified.

BACKGROUND: First-line pembrolizumab monotherapy improves overall and progression-free survival in patients with untreated metastatic non-small-cell lung cancer with a programmed death ligand 1 (PD-L1) tumour proportion score (TPS) of 50% or greater. We investigated overall survival after treatment with pembrolizumab monotherapy in patients with a PD-L1 TPS of 1% or greater. METHODS: This randomised, open-label, phase 3 study was done in 213 medical centres in 32 countries. Eligible patients were adults (≥18 years) with previously untreated locally advanced or metastatic non-small-cell lung cancer without a sensitising EGFR mutation or ALK translocation and with an Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1, life expectancy 3 months or longer, and a PD-L1 TPS of 1% or greater. Randomisation was computer generated, accessed via an interactive voice-response and integrated web-response system, and stratified by region of enrolment (east Asia vs rest of world), ECOG performance status score (0 vs 1), histology (squamous vs non-squamous), and PD-L1 TPS (≥50% vs 1-49%). Enrolled patients were randomly assigned 1:1 in blocks of four per stratum to receive pembrolizumab 200 mg every 3 weeks for up to 35 cycles or the investigator's choice of platinum-based chemotherapy for four to six cycles. Primary endpoints were overall survival in patients with a TPS of 50% or greater, 20% or greater, and 1% or greater (one-sided significance thresholds, p=0·0122, p=0·0120, and p=0·0124, respectively) in the intention-to-treat population, assessed sequentially if the previous findings were significant. This study is registered at ClinicalTrials.gov, number NCT02220894. FINDINGS: From Dec 19, 2014, to March 6, 2017, 1274 patients (902 men, 372 women, median age 63 years [IQR 57-69]) with a PD-L1 TPS of 1% or greater were allocated to pembrolizumab (n=637) or chemotherapy (n=637) and included in the intention-to-treat population. 599 (47%) had a TPS of 50% or greater and 818 patients (64%) had a TPS of 20% or greater. As of Feb 26, 2018, median follow-up was 12·8 months. Overall survival was significantly longer in the pembrolizumab group than in the chemotherapy group in all three TPS populations (≥50% hazard ratio 0·69, 95% CI 0·56-0·85, p=0·0003; ≥20% 0·77, 0·64-0·92, p=0·0020, and ≥1% 0·81, 0·71-0·93, p=0·0018). The median surival values by TPS population were 20·0 months (95% CI 15·4-24·9) for pembrolizumab versus 12·2 months (10·4-14·2) for chemotherapy, 17·7 months (15·3-22·1) versus 13·0 months (11·6-15·3), and 16·7 months (13·9-19·7) versus 12·1 months (11·3-13·3), respectively. Treatment-related adverse events of grade 3 or worse occurred in 113 (18%) of 636 treated patients in the pembrolizumab group and in 252 (41%) of 615 in the chemotherapy group and led to death in 13 (2%) and 14 (2%) patients, respectively. INTERPRETATION: The benefit-to-risk profile suggests that pembrolizumab monotherapy can be extended as first-line therapy to patients with locally advanced or metastatic non-small-cell lung cancer without sensitising EGFR or ALK alterations and with low PD-L1 TPS.

BACKGROUND: Most patients with locally advanced, unresectable, non-small-cell lung cancer (NSCLC) have disease progression despite definitive chemoradiotherapy (chemotherapy plus concurrent radiation therapy). This phase 3 study compared the anti-programmed death ligand 1 antibody durvalumab as consolidation therapy with placebo in patients with stage III NSCLC who did not have disease progression after two or more cycles of platinum-based chemoradiotherapy. METHODS: We randomly assigned patients, in a 2:1 ratio, to receive durvalumab (at a dose of 10 mg per kilogram of body weight intravenously) or placebo every 2 weeks for up to 12 months. The study drug was administered 1 to 42 days after the patients had received chemoradiotherapy. The coprimary end points were progression-free survival (as assessed by means of blinded independent central review) and overall survival (unplanned for the interim analysis). Secondary end points included 12-month and 18-month progression-free survival rates, the objective response rate, the duration of response, the time to death or distant metastasis, and safety. RESULTS: Of 713 patients who underwent randomization, 709 received consolidation therapy (473 received durvalumab and 236 received placebo). The median progression-free survival from randomization was 16.8 months (95% confidence interval [CI], 13.0 to 18.1) with durvalumab versus 5.6 months (95% CI, 4.6 to 7.8) with placebo (stratified hazard ratio for disease progression or death, 0.52; 95% CI, 0.42 to 0.65; P<0.001); the 12-month progression-free survival rate was 55.9% versus 35.3%, and the 18-month progression-free survival rate was 44.2% versus 27.0%. The response rate was higher with durvalumab than with placebo (28.4% vs. 16.0%; P<0.001), and the median duration of response was longer (72.8% vs. 46.8% of the patients had an ongoing response at 18 months). The median time to death or distant metastasis was longer with durvalumab than with placebo (23.2 months vs. 14.6 months; P<0.001). Grade 3 or 4 adverse events occurred in 29.9% of the patients who received durvalumab and 26.1% of those who received placebo; the most common adverse event of grade 3 or 4 was pneumonia (4.4% and 3.8%, respectively). A total of 15.4% of patients in the durvalumab group and 9.8% of those in the placebo group discontinued the study drug because of adverse events. CONCLUSIONS: Progression-free survival was significantly longer with durvalumab than with placebo. The secondary end points also favored durvalumab, and safety was similar between the groups.

BACKGROUND: The current randomized, double-blind, phase 2 study assessed the efficacy and safety profile of a single intravenous administration of fosnetupitant, a neurokinin 1 receptor antagonist prodrug, for the prevention of chemotherapy-induced nausea and vomiting in Japanese patients receiving cisplatin-based chemotherapy. METHODS: Patients scheduled to receive cisplatin (at a dose of ≥70 mg/m2 )-based regimens were randomly assigned to receive fosnetupitant at a dose of 81 mg or 235 mg or placebo in combination with palonosetron at a dose of 0.75 mg and dexamethasone. The primary endpoint was complete response (CR; no vomiting and no rescue medication) during the overall phase (0-120 hours). The overall CR rate was compared between each dose of fosnetupitant and the placebo group adjusting for the stratification factors of sex and age class (age <55 years vs age ≥55 years). Safety was assessed, with special attention given to events that potentially were suggestive of infusion site reactions. RESULTS: A total of 594 patients were randomized. Of these, 194 patients, 195 patients, and 195 patients, respectively, in the placebo and fosnetupitant 81-mg and 235-mg dose groups were evaluable for efficacy. The overall CR rate was 54.7% for the placebo group, 63.8% for the fosnetupitant 81-mg dose group (adjusted difference, 9.1%; 95% CI, -0.4% to 18.6% [P = .061]), and 76.8% for the fosnetupitant 235-mg dose group (adjusted difference, 22.0%; 97.5% CI, 11.7% to 32.3% [P < .001]). Safety profiles were comparable between the 3 groups. The incidence of infusion site reactions related to fosnetupitant was ≤1% in each dose group. CONCLUSIONS: Fosnetupitant at a dose of 235 mg provided superior prevention of chemotherapy-induced nausea and vomiting among patients receiving cisplatin-based chemotherapy compared with the control group, and with a satisfactory safety profile.

Purpose We investigated the safety, tolerability, pharmacokinetics, and efficacy of TAS-121, a novel, potent, and highly selective third-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in Japanese patients with advanced EGFR mutation-positive non-small-cell lung cancer (NSCLC) previously treated with EGFR-TKI. Methods This was an open-label, non-randomized, multi-center, dose escalation, phase I study conducted in three phases (dose escalation, expansion, and extension phases). TAS-121 was administered orally once daily (QD) or twice daily (BID) under fasting conditions in a 21-day treatment cycle. The primary endpoint was dose-limiting toxicities (DLTs) during Cycle 1 of the dose escalation phase. Results In total, 134 patients received treatment. Five and three patients presented a DLT with the QD and BID regimens, respectively. The DLTs were drug-induced liver injury, platelet count decreased, urticaria, interstitial lung disease, and left ventricular failure. The maximum tolerated dose (MTD) was 10 mg/day QD and 8 mg/day BID in the dose escalation phase. The most common adverse drug reactions (ADRs) were dermatological toxicity (89.6%), platelet count decreased (67.2%), and pyrexia (44%) among all patients. Rate of discontinuations due to ADRs at the MTD level were 11.1% with TAS-121 10 mg/day QD and 7.9% with TAS-121 8 mg/day BID. Among 86 T790M-positive patients (confirmed by blood serum sampling in most patients), the objective response rate (ORR) was 28% and highest at 8 mg/day BID (39%). Among 16 T790M-negative patients, the ORR was 19%. Conclusions TAS-121 was well tolerated up to the MTD and demonstrated antitumor activity in Japanese T790M-positive NSCLC patients.

OBJECTIVE: Netupitant is a novel, selective neurokinin-1 receptor antagonist used for prevention of chemotherapy-induced nausea and vomiting, a distressing side effect of chemotherapy. This double-blind, randomized, Phase II study investigated the dose-response of oral netupitant in Japanese patients receiving highly emetogenic chemotherapy. METHODS: Chemotherapy-naïve patients were randomized (1:1:1) to a single oral netupitant 30-, 100- or 300-mg dose before chemotherapy initiation. Patients received concomitant palonosetron (0.75 mg intravenously [i.v.] Day 1) and dexamethasone (9.9 mg i.v. Day 1, 8 mg orally Days 2-4). RESULTS: Overall, 402 patients (30 mg: 134; 100 mg: 135; 300 mg: 133) were treated and evaluable for efficacy and safety. The primary endpoint of overall (0-120 h after chemotherapy administration) complete response (CR) rate (no emesis, no rescue medication) was 64.2%, 60.0% and 54.9% in the 30-, 100- and 300-mg arms, respectively, without statistical significance for dose-response. The safety profile of netupitant was comparable in the three arms. The plasma concentrations of netupitant and its metabolites increased with the dose increase from 30 mg to 300 mg. CONCLUSIONS: No dose-response relationship of netupitant in terms of overall CR rate was observed in this study. Netupitant was well tolerated at all doses without clinically harmful safety signals observed. CLINICAL TRIAL REGISTRATION: JapicCTI-142 483.

BACKGROUND: Nanoparticle albumin-bound paclitaxel is indicated for the treatment of patients with lung cancer. It can induce interstitial lung disease, but the incidence of nanoparticle albumin-bound paclitaxel-associated interstitial lung disease in clinical practice has not been determined. We investigated the incidence of interstitial lung disease in patients with lung cancer who had received nanoparticle albumin-bound paclitaxel therapy at our institution. METHODS: We reviewed clinical data for patients with advanced lung cancer who received nanoparticle albumin-bound paclitaxel with or without carboplatin or bevacizumab therapy at the Nippon Medical School Main Hospital between April 2013 and September 2017. Interstitial lung disease was diagnosed based on clinical symptoms, radiographic findings and exclusion of other diseases. RESULTS: A total of 110 advanced lung cancer patients received nanoparticle albumin-bound paclitaxel, and nine of them (8.2%) developed interstitial lung disease. Of those who developed interstitial lung disease, eight were treated with corticosteroids and three received cyclophosphamide pulse therapy. High-resolution computed tomography images demonstrated diffuse alveolar damage pattern pneumonitis in seven patients and organized pneumonia pattern pneumonitis in two patients. Six of the patients with diffuse alveolar damage pattern pneumonitis died from respiratory failure. The two patients with organized pneumonia pattern pneumonitis recovered. The incidence of interstitial lung disease was 19.0% (8/42) among patients with preexisting interstitial pneumonia and 1.5% (1/68) among those without preexisting interstitial pneumonia. Six patients with preexisting interstitial pneumonia met the criteria for acute exacerbation of interstitial pneumonia (14.3%). CONCLUSION: Nanoparticle albumin-bound paclitaxel-associated interstitial lung disease was a severe and potentially fatal adverse event. We found it demonstrated diffuse alveolar damage or organized pneumonia pattern pneumonitis, and preexisting interstitial pneumonia was associated with higher rate of nanoparticle albumin-bound paclitaxel-associated interstitial lung disease.

BACKGROUND: S-1 plus cisplatin is a standard chemotherapy regimen for advanced non-small cell lung cancer (NSCLC). The addition of bevacizumab has been shown to significantly improve overall survival (OS) in patients with advanced non-squamous (NSq) NSCLC who received carboplatin plus paclitaxel, however, failed to show an OS advantage in patients who received cisplatin plus gemcitabine. METHODS: Chemotherapy-naive patients with Stage IIIB, IV or recurrent non-SQ NSCLC were treated with a 3-week cycle of S-1 80 mg/m2 on days 1-14, cisplatin 60 mg/m2 on day 8 and bevacizumab 15 mg/kg on day 8 for 4-6 cycles. Patients without progressive disease (PD) received maintenance bevacizumab 15 mg/kg on day 1 with a 3-week cycle and S-1 80 mg/m2 every other day. The primary endpoint was progression-free survival (PFS). Secondary endpoints were objective response rate (ORR), OS, toxicity profile and Quality of life (QOL). RESULTS: From June 2013 to January 2015, 39 eligible patients were enrolled from eight institutions. Thirty-one patients (79%) completed four cycles of induction chemotherapy, and maintenance chemotherapy was initiated in 23 patients (59%). Median PFS, OS and ORR were 7.3 months (95% CI: 5.9-8.7), 21.4 months (95% CI: 14.7-not reached) and 64%, respectively. The most common grade 3/4 toxicities were leukopenia (12.8%), neutropenia (23.0%) and hypertension (28.2%). QOL analyses showed detrimental effects after initiation of the regimen. CONCLUSIONS: S-1 plus cisplatin in combination with bevacizumab met the primary endpoint in patients with advanced NSq-NSCLC. RR was anticipated to be high with acceptable toxicities.

BACKGROUND: Idiopathic interstitial pneumonias (IIPs) are associated with increased risk of lung cancer. In Japan, acute exaberation of IIPs induced by anticancer treatment is a critical issue. For this reason, there is limited available evidence regarding the optimal treatment approach for lung cancer patients complicated with IIPs. Our previous prospective pilot study demonstrated the safety and efficacy of weekly paclitaxel in combination with carboplatin for advanced non-small-cell lung cancer (NSCLC) with IIPs. The current study was conducted to confirm the results of the same combination therapy used in a larger patient population. METHODS: Chemotherapy-naïve patients with advanced stage or post-operative recurrent NSCLC patients complicated by IIPs were enrolled. Patients received paclitaxel (100 mg/m2) on days 1, 8, and 15, and carboplatin (AUC 5.0) once every 4 weeks. RESULTS: Thirty-three of 35 enrolled patients were evaluable for analysis and received a median of four treatment cycles (range 1-6). Four patients (12.1%; 95% confidence interval 3.4-28.2%) had acute exacerbation (AEx)-related IIPs to the study treatment. However, no fatalities due to AEx were observed. The overall response was 69.7%. The median progression-free survival, median survival time, and 1-year survival were 6.3 months, 19.8 months, and 55.4%, respectively. CONCLUSIONS: The efficacy of carboplatin plus weekly paclitaxel treatment for advanced NSCLC patients with IIPs was comparable to that of conventional chemotherapy in advanced NSCLC patients without IIPs. Moreover, the primary endpoint was set to the frequency of treatment-related acute exacerbation, and the primary endpoint was met. These results suggest that patients with advanced NSCLC complicated by IIPs may benefit from this combination chemotherapy.
