Background More and more preclinical studies support the idea that curcumin, a plant-derived natural polyphenol, could be a promising anticancer drug. However, poor bioavailability has limited its efficacy in clinical trials, and plasma curcumin levels remain low despite patients taking gram doses of curcumin. Methods This study aimed to evaluate the safety and pharmacokinetics of newly developed nanoparticle curcumin with increased water solubility (named THERACURMIN). Six healthy human volunteers were recruited and received THERACURMIN at a single oral dose of 150 mg. After an interval of 2 weeks, the same subjects then received THERACURMIN at a single dose of 210 mg. Plasma curcumin levels were measured at 0, 1, 2, 4, 6, and 24 h after THERACURMIN intake using high-performance liquid chromatography (HPLC). Results One subject reported grade 1 diarrhea after intake of 150 mg THERACURMIN. No other toxicities were observed in this study. C max for THERACURMIN at 150 and 210 mg was 189 ± 48 and 275 ± 67 ng/ml (mean ± SEM), respectively, and the area under the curve for 24 h was estimated to be 2,649 ± 350 and 3,649 ± 430 ng/ml × h (mean ± SEM), respectively. The t 1/2 was estimated to be 9.7 ± 2.1 h for 150 mg and 13.0 ± 3.3 h for 210 mg. Conclusion THERACURMIN can safely increase plasma curcumin levels in a dose-dependent manner at least up to 210 mg without saturating the absorption system. To the best of our knowledge, THERACURMIN is the first nanoparticle formulation of curcumin that demonstrates improved bioavailability in human subjects. We believe this compound could be a promising tool when testing the potential anticancer effects of curcumin in clinical trials.

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.

Optimal treatment regimens for AIDS-associated Kaposi sarcoma, a frequent contributor to morbidity and mortality among people with HIV, have not been systematically evaluated in low-income and middle-income countries, where the disease is most common. In this study, we aimed to investigate optimal treatment strategies for advanced stage disease in areas of high prevalence and limited resources. In this open-label, non-inferiority trial, we enrolled people with HIV and advanced stage AIDS-associated Kaposi sarcoma attending 11 AIDS Clinical Trials Group sites in Brazil, Kenya, Malawi, South Africa, Uganda, and Zimbabwe. Eligible participants were randomly assigned (1:1:1) with a centralised computer system to receive either intravenous bleomycin and vincristine or oral etoposide (the investigational arms), or intravenous paclitaxel (the control arm), together with antiretroviral therapy (ART; combined efavirenz, tenofovir disoproxil fumarate, and emtricitabine). The primary outcome was progression-free survival (PFS) at week 48, using a 15% non-inferiority margin to compare the investigational groups against the active control group. Safety was assessed in all eligible treated study participants. The study was registered with ClinicalTrials.gov, NCT01435018. 334 participants were enrolled between Oct 1, 2013, and March 8, 2018, when the study was closed early due to inferiority of the bleomycin and vincristine plus ART arm, as per the recommendations of the Data and Safety Monitoring Board (DSMB). The etoposide plus ART arm also closed due to inferiority in March, 2016, following a DSMB recommendation. Week-48 PFS rates were higher in the paclitaxel plus ART arm than in both investigational arms. The absolute differences in PFS were −30% (95% CI −52 to −8) for the comparison of paclitaxel plus ART (week 48 PFS 50%, 32 to 67; n=59) and etoposide plus ART (20%, 6 to 33; n=59), and −20% (−33% to −7%) for the comparison of paclitaxel plus ART (64%, 55 to 73; n=138) and bleomycin and vincristine plus ART (44%, 35 to 53; n=132). Both CIs overlapped the non-inferiority margin. The most common adverse events, in 329 eligible participants who began treatment, were neutropenia (48 [15%]), low serum albumin (33 [10%]), weight loss (29 [9%]), and anaemia (28 [9%]), occurring at similar frequency across treatment arms. Non-inferiority of either investigational intervention was not shown, with paclitaxel plus ART showing superiority to both oral etoposide plus ART and bleomycin and vincristine plus ART, supporting its use in treating advanced AIDS-associated Kaposi sarcoma in resource-limited settings.

Background The biological effect of oral metronomic vinorelbine (mVNB) alone or in combination with endocrine therapy in patients with hormone receptor-positive (HR+)/HER2-negative breast cancer has been scarcely addressed. Methods Postmenopausal women with untreated stage I–III HR+/HER2-negative breast cancer were randomized (1:1:1) to receive 3 weeks of letrozole (LTZ) 2.5 mg/day, oral mVNB 50 mg 3 days/week, or the combination. The primary objective was to evaluate, within PAM50 Luminal A/B disease, if the anti-proliferative effect of LTZ+mVNB was superior to monotherapy. An anti-proliferative effect was defined as the mean relative decrease of the PAM50 11-gene proliferation score in combination arm vs. both monotherapy arms. Secondary objectives included the evaluation of a comprehensive panel of breast cancer-related genes and safety. An unplanned analysis of stromal tumor-infiltrating lymphocytes (sTILs) was also performed. PAM50 analyses were performed using the nCounter®-based Breast Cancer 360™ gene panel, which includes 752 genes and 32 signatures. Results Sixty-one patients were randomized, and 54 paired samples (89%) were analyzed. The main patient characteristics were mean age of 67, mean tumor size of 1.7 cm, mean Ki67 of 14.3%, stage I (55.7%), and grades 1–2 (90%). Most baseline samples were PAM50 Luminal A (74.1%) or B (22.2%). The anti-proliferative effect of 3 weeks of LTZ+mVNB (− 73.2%) was superior to both monotherapy arms combined (− 49.9%; p  = 0.001) and mVNB (− 19.1%; p  < 0.001). The anti-proliferative effect of LTZ+mVNB (− 73.2%) was numerically higher compared to LTZ (− 65.7%) but did not reach statistical significance ( p  = 0.328). LTZ+mVNB induced high expression of immune-related genes and gene signatures, including CD8 T cell signature and PDL1 gene and low expression of ER-regulated genes (e.g., progesterone receptor) and cell cycle-related and DNA repair genes. In tumors with ≤ 10% sTILs at baseline, a statistically significant increase in sTILs was observed following LTZ (paired analysis p  = 0.049) and LTZ+mVNB ( p  = 0.012). Grade 3 adverse events occurred in 3.4% of the cases. Conclusions Short-term mVNB is well-tolerated and presents anti-proliferative activity alone and in combination with LTZ. The high expression of immune-related biological processes and sTILs observed with the combination opens the possibility of studying this combination with immunotherapy. Further investigation comparing these biological results with other metronomic schedules or drug combinations is warranted. Trial registration NCT02802748 , registered 16 June 2016.

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.

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.

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.

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.

Multiple paclitaxel-based regimens are widely used in chemoradiation therapy against esophageal cancer, including regimens combining paclitaxel with fluorouracil, cisplatin, and carboplatin. However, which among these 3 regimens provides the best prognosis with minimum adverse events is still unknown. To compare the efficacy and adverse events of fluorouracil, cisplatin, and carboplatin in definitive chemoradiotherapy in patients with esophageal squamous cell carcinoma (ESCC). This randomized clinical trial of patients with ESCC was conducted in 11 treatment centers in China. Eligible patients were aged 18 to 75 years and had histologically confirmed ESCC stages IIa to IVa with no prior treatment, Eastern Cooperative Oncology Group performance status of 2 or lower, and adequate organ functions. The study was conducted between July 2015 and February 2018, and the cutoff date for data analysis was August 31, 2020. Patients with locally advanced ESCC were randomly assigned (1:1:1) to groups combining paclitaxel treatment with fluorouracil, cisplatin, or carboplatin. Patients in the cisplatin group were treated with 2 cycles of concurrent chemoradiotherapy followed by 2 cycles of consolidation chemotherapy with monthly paclitaxel plus cisplatin. For the fluorouracil group, patients were administered 6 cycles of weekly paclitaxel plus fluorouracil in concurrent chemoradiotherapy followed by 2 cycles of monthly paclitaxel plus fluorouracil in consolidation chemotherapy. Patients in the carboplatin group were treated with 6 cycles of weekly paclitaxel plus carboplatin in concurrent chemoradiotherapy followed by 2 cycles of monthly paclitaxel plus carboplatin in consolidation chemotherapy. All patients received radiotherapy of 61.2 Gy delivered in 34 fractions. The primary end point was overall survival (OS). The secondary end points were progression-free survival and adverse events. Overall, 321 patients (median [IQR] age, 64 years [59-69 years]; 248 [77.3%] men) with ESCC from 11 centers were randomized into fluorouracil, cisplatin, or carboplatin groups between July 2015 and February 2018. Over a median (IQR) follow-up time of surviving patients of 46.0 months (36.6-53.0 months), the 3-year OS rates were 57.2% in the fluorouracil group, 60.1% in the cisplatin group, and 56.5% in the carboplatin group, respectively (fluorouracil vs cisplatin: HR, 1.06; 95% CI, 0.71-1.60; P = .77; fluorouracil vs carboplatin: HR, 0.94; 95% CI, 0.63-1.40; P = .77). The cisplatin group had significantly higher incidences of acute grade 3 or 4 neutropenia (69 events [60.8%] vs 19 [17.8%] for fluorouracil and 37 [34.6%] carboplatin; P < .001), thrombocytopenia (14 events [13.1%] vs 4 [3.7%] for fluorouracil and 5 [4.7%] for carboplatin; P = .01), anemia (50 events above grade 2 [46.7%] vs 25 [23.4%] for fluorouracil and 37 [34.6%] for carboplatin; P = .35), fatigue (11 events [10.3%] vs 2 [1.9%] for fluorouracil and 1 [0.9%] carboplatin; P = .007), and vomiting (17 events above grade 2 [15.9%] vs 3 [2.8%] for fluorouracil and 5 [4.7%] for carboplatin; P < .001) than the other 2 groups. In this randomized clinical trial, paclitaxel plus fluorouracil did not show OS superiority over paclitaxel plus cisplatin or paclitaxel plus carboplatin regimens in definitive chemoradiation in patients with locally advanced ESCC. Higher rates of hematologic and gastrointestinal toxic effects were reported in the cisplatin group compared with those in the fluorouracil or carboplatin groups.
