Antibodies targeting the immune checkpoint molecules PD-1 or PD-L1 have demonstrated clinical efficacy in patients with metastatic non-small-cell lung cancer (NSCLC). In this trial we investigated the efficacy and safety of avelumab, an anti-PD-L1 antibody, in patients with NSCLC who had already received platinum-based therapy. JAVELIN Lung 200 was a multicentre, open-label, randomised, phase 3 trial at 173 hospitals and cancer treatment centres in 31 countries. Eligible patients were aged 18 years or older and had stage IIIB or IV or recurrent NSCLC and disease progression after treatment with a platinum-containing doublet, an Eastern Cooperative Oncology Group performance status score of 0 or 1, an estimated life expectancy of more than 12 weeks, and adequate haematological, renal, and hepatic function. Participants were randomly assigned (1:1), via an interactive voice-response system with a stratified permuted block method with variable block length, to receive either avelumab 10 mg/kg every 2 weeks or docetaxel 75 mg/m2 every 3 weeks. Randomisation was stratified by PD-L1 expression (≥1% vs <1% of tumour cells), which was measured with the 73–10 assay, and histology (squamous vs non-squamous). The primary endpoint was overall survival, analysed when roughly 337 events (deaths) had occurred in the PD-L1-positive population. Efficacy was analysed in all PD-L1-positive patients (ie, PD-L1 expression in ≥1% of tumour cells) randomly assigned to study treatment (the primary analysis population) and then in all randomly assigned patients through a hierarchical testing procedure. Safety was analysed in all patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov, number NCT02395172. Enrolment is complete, but the trial is ongoing. Between March 24, 2015, and Jan 23, 2017, 792 patients were enrolled and randomly assigned to receive avelumab (n=396) or docetaxel (n=396). 264 participants in the avelumab group and 265 in the docetaxel group had PD-L1-positive tumours. In patients with PD-L1-positive tumours, median overall survival did not differ significantly between the avelumab and docetaxel groups (11·4 months [95% CI 9·4–13·9] vs 10·3 months [8·5–13·0]; hazard ratio 0·90 [96% CI 0·72–1·12]; one-sided p=0·16). Treatment-related adverse events occurred in 251 (64%) of 393 avelumab-treated patients and 313 (86%) of 365 docetaxel-treated patients, including grade 3–5 events in 39 (10%) and 180 (49%) patients, respectively. The most common grade 3–5 treatment-related adverse events were infusion-related reaction (six patients [2%]) and increased lipase (four [1%]) in the avelumab group and neutropenia (51 [14%]), febrile neutropenia (37 [10%]), and decreased neutrophil counts (36 [10%]) in the docetaxel group. Serious treatment-related adverse events occurred in 34 (9%) patients in the avelumab group and 75 (21%) in the docetaxel group. Treatment-related deaths occurred in four (1%) participants in the avelumab group, two due to interstitial lung disease, one due to acute kidney injury, and one due to a combination of autoimmune myocarditis, acute cardiac failure, and respiratory failure. Treatment-related deaths occurred in 14 (4%) patients in the docetaxel group, three due to pneumonia, and one each due to febrile neutropenia, septic shock, febrile neutropenia with septic shock, acute respiratory failure, cardiovascular insufficiency, renal impairment, leucopenia with mucosal inflammation and pyrexia, infection, neutropenic infection, dehydration, and unknown causes. Compared with docetaxel, avelumab did not improve overall survival in patients with platinum-treated PD-L1-positive NSCLC, but had a favourable safety profile. Merck and Pfizer.

The phase III KEYNOTE-604 study confirmed the benefit of pembrolizumab combined with chemotherapy in the first-line treatment of extensive-stage small-cell lung cancer (ES-SCLC). Taken into account the clinical benefits of pembrolizumab and its high cost, this study aimed to assess the cost-effectiveness of adding pembrolizumab to standard first-line etoposide-platinum (EP) for patients with ES-SCLC from the US payer perspective. A Markov model was developed to compare the cost and quality-adjusted life-year (QALY) of pembrolizumab plus EP and placebo plus EP over a 10-year time horizon. Clinical efficacy and safety data were pooled from the KEYNOTE-604 trial. Utilities were obtained from published resources. Costs were mainly collected from Medicare in 2020. Sensitivity analyses were performed to examine the robustness of our model. Adding pembrolizumab to standard first-line EP resulted in the better effectiveness than EP chemotherapy alone for ES-SCLC by 0.22 QALYs. Pembrolizumab plus EP was dominated economically by placebo plus EP, leading to an incremental cost-effectiveness ratio (ICER) of $334,373/ QALY. Deterministic sensitivity analyses indicated that the uncertainty in model parameters exerted no substantial effect on our results. Probability sensitivity analysis indicated that probabilities for pembrolizumab plus EP being cost-effective within a wide range of willingness to pay were modest. From the US payer perspective, the first-line treatment for ES-SCLC with pembrolizumab plus EP was not cost-effective compared with placebo plus EP. Although pembrolizumab combination chemotherapy was beneficial to the survival of ES-SCLC, price reduction may be the necessary to improve its cost-effectiveness.

Patients with advanced HER2-positive breast cancer frequently develop CNS metastases. The metastases that progress after brain radiotherapy and HER2-targeted systemic therapy are a difficult therapeutic challenge. We aimed to assess the efficacy and safety of afatinib, an irreversible blocker of the ErbB protein family, alone or combined with vinorelbine, compared with treatment of the investigator's choice in women with HER2-positive breast cancer with progressive brain metastases during or after treatment with trastuzumab, lapatinib, or both. We did this randomised, open-label, multicentre, phase 2 trial in 40 hospitals in Canada, Finland, France, Germany, Italy, Spain, South Korea, and the USA. Women older than 18 years with histologically confirmed HER2-overexpressing breast cancer and CNS recurrence or progression as determined by Response Evaluation Criteria in Solid Tumors (RECIST version 1.1) during or after treatment with trastuzumab, lapatinib, or both, were eligible. We randomly assigned patients (1:1:1) centrally to afatinib 40 mg orally once per day, afatinib 40 mg per day plus intravenous vinorelbine 25 mg/m2 once per week, or investigator's choice of treatment in cycles of 3 weeks until disease progression, patient withdrawal, or unacceptable toxicity. Treatment assignment was not masked for clinicians or patients, but the trial team was masked until database lock to reduce bias. The primary endpoint, assessed in the intention-to-treat population, was patient benefit at 12 weeks, defined by an absence of CNS or extra-CNS disease progression, no tumour-related worsening of neurological signs or symptoms, and no increase in corticosteroid dose. Safety was assessed in all patients who received at least one dose of a study drug. This completed trial is registered with ClinicalTrials.gov, number NCT01441596. Between Dec 22, 2011, and Feb 12, 2013, we screened 132 patients, of whom 121 were eligible and randomly assigned to treatment: 40 to afatinib alone, 38 to afatinib plus vinorelbine, and 43 to investigator's choice. All patients discontinued study treatment before the data collection cutoff on Oct 16, 2014. Patient benefit was achieved in 12 (30·0%; 95% CI 16·6–46·5) patients given afatinib alone (difference vs investigator's choice: −11·9% [95% CI −32·9 to 9·7], p=0·37), 13 (34·2%; 19·6–51·4) given afatinib plus vinorelbine (difference vs investigator's choice: −7·6% [–28·9 to 14·2], p=0·63), and 18 (41·9%; 27·0–57·9) given investigator's choice. The most common treatment-related grade 3 or 4 adverse events were diarrhoea (seven [18%] of 40 patients in the afatinib only group vs nine [24%] of 37 patients in the afatinib plus vinorelbine group vs two [5%] of 42 patients in the investigator's choice group) and neutropenia (none vs 14 [38%] vs four [10%]). Patient benefit with afatinib-containing treatments was not different from that in patients given investigator's choice of treatments; however, adverse events were frequent and afatinib-containing treatments seemed to be less well tolerated. No further development of afatinib for HER2-positive breast cancer is currently planned. Boehringer Ingelheim.

Purpose The aim of the current study was to evaluate the effect of N-acetylcysteine (NAC) on the incidence and severity of paclitaxel-induced peripheral neuropathy (PIPN) in breast cancer patients. Method A prospective randomized controlled open label study was conducted on 75 breast cancer patients receiving adjuvant paclitaxel 80 mg/m 2 weekly for 12 weeks. Eligible patients were randomized to either the low dose group; 1200 mg daily NAC, the high dose group; 1200 mg NAC twice daily or the control group; received paclitaxel only. The primary endpoint was the incidence of different grades of PIPN using National Cancer Institute’s common toxicity criteria for adverse event (NCI-CTCAE) while secondary endpoints were the severity of PIPN using modified total neuropathy score (mTNS), quality of life (QOL) using Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT-GOG-NTX) subscale, serum nerve growth factor (NGF), and serum malondialdehyde (MDA). Results At the end of the 12-week period, the incidence of grade (2, 3) peripheral neuropathy was significantly lower in the high dose group (28.6%) compared to the low dose group (61.9%) and the control group (100%), p value < 0.001. A significant improvement in the mTNS and QOL scores was observed after 6 and 12 weeks in the high dose group and the low dose group compared to the control, p value < 0.001. Significantly higher levels of serum NGF in the high dose group and lower level of serum MDA in the high dose and the low dose group were observed. Conclusion Oral NAC (1200 mg once and twice daily) might reduce the incidence and severity of PIPN and improve the patients’ QOL. Trial registry Clinical Trial.gov registration number: NCT03492047.

Oral fluoropyrimidines are used for the first-line treatment of metastatic breast cancer to avoid severe adverse effects, although firm supporting evidence is lacking. We aimed to establish whether S-1 is non-inferior to taxanes in this setting. We did an open-label, non-inferiority, phase 3 trial at 154 hospitals in Japan. We enrolled individuals who had HER2-negative metastatic breast cancer who had received no chemotherapy for advanced disease, and who were resistant to endocrine treatment. Patients were randomly assigned (1:1) either to taxane (docetaxel 60–75 mg/m2 at intervals of 3–4 weeks; paclitaxel 80–100 mg/m2 weekly for 3 of 4 weeks; or paclitaxel 175 mg/m2 at intervals of 3–4 weeks) or to S-1 (40–60 mg twice daily for 28 consecutive days, followed by a 14-day break). Randomisation was done centrally with the minimisation method, with stratification by institution, liver metastasis, oestrogen and progesterone receptor status, previous treatment with taxanes or oral fluorouracil, and time from surgery to recurrence. The primary endpoint was overall survival, with a prespecified non-inferiority margin of 1·333 for the hazard ratio (HR). The primary efficacy analysis was done in the full analysis set, which consisted of all patients who took at least one study treatment and who had all data after randomisation. This trial is registered with the University Hospital Medical Information Network, Japan (protocol ID C000000416). Between Oct 27, 2006, and July 30, 2010, we enrolled 618 patients (309 assigned to taxane; 309 assigned to S-1). The full analysis set consisted of 286 patients in the taxane group and 306 in the S-1 group. Median follow-up was 34·6 months (IQR 17·9–44·4). Median overall survival was 35·0 months (95% CI 31·1–39·0) in the S-1 group and 37·2 months (33·0–40·1) in the taxane group (HR 1·05 [95% CI 0·86–1·27]; pnon-inferiority=0·015). The most common grade 3 or worse adverse events were neutropenia (20 [7%] of 307 patients in the S-1 group vs nine [3%] of 290 patients in the taxane group), fatigue (ten [3%] vs 12 [4%]), and oedema (one [<1%] vs 12 [4%]). Treatment-related deaths were reported in two patients in the taxane group. S-1 is non-inferior to taxane with respect to overall survival as a first-line treatment for metastatic breast cancer. S-1 should be considered a new option for first-line chemotherapy for patients with HER2-negative metastatic breast cancer.

GBS‐01, an extract from the fruit of Arctium lappa L. is an orally administered drug rich in arctigenin, which has been reported to exert antitumor activity by attenuating the tolerance of cancer cells to glucose deprivation. We investigated the maximum tolerated dose of GBS‐01 based on the frequency of the dose‐limiting toxicities (DLTs) and pharmacokinetics in patients with advanced pancreatic cancer refractory to gemcitabine. GBS‐01 was given orally at escalating doses from 3.0 g (containing 1.0 g burdock fruit extract) to 12.0 g q.d. A DLT was defined as a grade 4 hematological toxicity and grade 3 or 4 non‐hematological toxicity appearing during the first 28 days of treatment. Fifteen patients (GBS‐01 dose level 1 [3.0 g], three patients; dose level 2 [7.5 g], three patients; and dose level 3 [12.0 g], nine patients) were enrolled. None of the patients at any of the three dose levels showed any sign of DLTs. The main adverse events were increased serum γ‐glutamyl transpeptidase, hyperglycemia, and increased serum total bilirubin; however, all the toxicities were mild. Of the 15 patients, 1 showed confirmed partial response and 4 patients had stable disease. The median progression‐free and overall survival of the patients were 1.1 and 5.7 months, respectively. The pharmacokinetic study revealed a high bioavailability of arctigenin and rapid conjugation of the drug with glucuronic acid. The recommended dose of GBS‐01 was 12.0 g q.d, and favorable clinical responses were obtained. This trial was registered at UMIN‐CTR (http://www.umin.ac.jp/ctr/index-j.htm), identification number UMIN000005787. GBS‐01 is as an orally available drug rich in arctigenin, which attenuates the tolerance of cancer cells to glucose starvation and hypoxia. This phase I trial revealed favorable clinical responses, mild toxicity and a high bioavailability of GBS‐01 in patients with advanced pancreatic cancer.

This trial tested the effect of adding bevacizumab, a monoclonal antibody against vascular endothelial growth factor A, to the taxane paclitaxel for the initial treatment of metastatic breast cancer. As compared with paclitaxel alone, the combination increased progression-free survival but not overall survival. The results are a demonstration of the potential benefit of antiangiogenic treatment for breast cancer. This trial tested the effect of adding bevacizumab, a monoclonal antibody against vascular endothelial growth factor A, to paclitaxel for the initial treatment of metastatic breast cancer. As compared with paclitaxel alone, the combination increased progression-free survival but not overall survival. Laboratory and clinical evidence supports the central role of angiogenesis in the progression of breast cancer. 1 , 2 Multiple angiogenic factors are commonly expressed by invasive breast cancers; the 121-amino-acid isoform of vascular endothelial growth factor (VEGF) predominates. 3 VEGF stimulates endothelial proliferation and migration, inhibits endothelial apoptosis, induces proteinases that remodel the extracellular matrix, increases vascular permeability and vasodilatation, and inhibits antigen-presenting dendritic cells. 4 Differences in function among the various VEGF isoforms are not well defined, though VEGF-C has a predominant role in lymphangiogenesis, whereas VEGF-A is more potent in inducing vasodilatation and pathologic angiogenesis. 5 , 6 Bevacizumab (Avastin, Genentech) is a . . .

Background NK105 is a novel nanoparticle drug delivery formulation that encapsulates paclitaxel (PTX) in polymeric micelles. We conducted an open-label phase III non-inferiority trial to compare the efficacy and safety of NK105 and PTX in metastatic or recurrent breast cancer. Methods Patients were randomly assigned in a 1:1 ratio to receive either NK105 (65 mg/m 2 ) or PTX (80 mg/m 2 ) on days 1, 8 and 15 of a 28-day cycle. The primary endpoint was progression-free survival (PFS), with a non-inferiority margin of 1.215. Results A total of 436 patients were randomised and 211 patients in each group were included in the efficacy analysis. The median PFS was 8.4 and 8.5 months for NK105 and PTX, respectively (adjusted hazard ratio: 1.255; 95% confidence interval: 0.989–1.592). The median overall survival and overall response rates were 31.2 vs. 36.2 months and 31.6% vs. 39.0%, respectively. The two groups exhibited similar safety profiles. The incidence of peripheral sensory neuropathy (PSN) was 1.4% vs. 7.5% (≥Grade 3) for NK105 and PTX, respectively. The patient-reported outcomes of PSN were significantly favourable for NK105 ( P  < 0.0001). Conclusions The primary endpoint was not met, but NK105 had a better PSN toxicity profile than PTX.

Background This phase I, four-arm, open-label study (NCT01347866) evaluated the PI3K/mTOR inhibitors PF-04691502 (arms A, B) and gedatolisib (PF-05212384; arms C, D) in combination with the MEK inhibitor PD-0325901 (arm A, D) or irinotecan (arm B, C) in patients with advanced solid tumors. Objectives Primary endpoint was dose-limiting toxicity with each combination. Secondary endpoints included safety, pharmacokinetics and preliminary antitumor activity. Patients and Methods Dose escalation followed a 3 + 3 design in arm C and a zone-based design in arm D. Results The PF-04691502 combination arms were closed prematurely due to low tolerability, and the maximum tolerated doses (MTDs) were not determined for either arm. The MTD for the combination of gedatolisib with irinotecan 180 mg/m 2 was estimated to be 110 mg weekly and for the combination with PD-0325901 was not reached at the highest dose evaluated (gedatolisib 154 mg weekly). Plasma concentrations of gedatolisib were generally similar across dose groups in arm C (with irinotecan) and arm D (with PD-0325901). Frequent dose delays or dose reductions were required for both combinations, potentially preventing sustained therapeutic drug concentrations. Gedatolisib plus irinotecan produced a response rate of ~5% and clinical benefit in 16% of patients with advanced colorectal cancer (progression-free survival, 2.8 months). Preliminary evidence of clinical activity was observed with gedatolisib plus PD-0325901 in patients with ovarian cancer (three partial responses, n  = 5) or endometrial cancer (one partial response, n  = 1) and KRAS mutations. Conclusions Further evaluations of gedatolisib are warranted in patients with advanced solid malignancies.

This randomized trial included almost 1500 women with breast cancer and positive axillary nodes and compared treatment with doxorubicin and cyclophosphamide combined with either fluorouracil or docetaxel. The rates of disease-free and overall survival were significantly higher among women in the docetaxel group. This trial compared treatment with doxorubicin and cyclophosphamide combined with either fluorouracil or docetaxel. The rates of disease-free and overall survival were significantly higher among women in the docetaxel group. Adjuvant chemotherapy for breast cancer has undergone a major change over the past two decades. Chemotherapy with a regimen that includes an anthracycline or a combination of cyclophosphamide, methotrexate, and fluorouracil significantly decreases the risks of disease recurrence and death among women with early-stage breast cancer. 1 The overview analysis of the Early Breast Cancer Trialists' Collaborative Group demonstrated that, as compared with standard treatment with cyclophosphamide, methotrexate, and fluorouracil, regimens that contained doxorubicin or epirubicin reduced the annual risk of recurrence of breast cancer by 12 percent and the annual risk of death by 11 percent.
