A Randomized, Double Blind, Placebo Controlled, Parallel-Group Study to Evaluate the Safety and Efficacy of Curene® versus Placebo in Reducing Symptoms of Knee OA.

Background Curene® is a bioavailable formulation of turmeric Curcucma longa extract comprising naturally derived curcuminoids formulated with proprietary Aquasome® technology. Curcuminoids were found to have anti-inflammatory properties by inhibiting Cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) enzyme and hence have potential application in the treatment of Osteoarthritis (OA). To evaluate the safety and efficacy of Curene® a randomized, double blind, placebo controlled, parallel-group study was conducted in subjects with knee OA. Significant improvements in clinical endpoints were observed during the trial along with excellent safety profile. Methods Fifty (50) subjects aged between 40 and 75 years who were suffering from unilateral or bilateral OA of the knee for greater than 3 months according to American College of Rheumatology (ACR) criteria were enrolled. They were randomized into two treatment groups; one group received Curene® 500 mg once daily and the other group received placebo. Efficacy was evaluated using change from baseline in Visual Analogue Scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score. Biochemical and hematological parameters including urine analysis were performed to evaluate the safety of Curene® in OA patients. Result Forty-six (46) subjects completed the study. The reduction from baseline in total WOMAC score (also subscale scores) and VAS score resulted in statistically significant difference when compared to placebo. It was also found to be safe and well tolerated as there was no incidence of treatment related AEs. Conclusion Curene® results in statistically significant and clinically meaningful reduction in pain, stiffness, and improvement in physical functioning in subjects suffering from knee OA. Curene® also demonstrates excellent safety profile during the study.

Lenvatinib as a novel treatment for anaplastic thyroid cancer: A retrospective study.

Anaplastic thyroid cancer (ATC) is associated with an extremely poor prognosis and is resistant to the majority of chemotherapies. In 2015, lenvatinib was approved for treating ATC in Japan. The present study aimed to evaluate the overall survival (OS) of patients with ATC treated with lenvatinib. A total of 23 patients with a definitive histological diagnosis of ATC who were treated at Kanagawa Cancer Center (Yokohama, Kanagawa. Japan) were enrolled. Surgical treatment was possible in 10 patients (including one debulking surgery), and lenvatinib treatment was postoperatively started. The remaining 13 patients were not eligible for debulking surgery; thus, lenvatinib was promptly approved as a life-saving treatment. The therapeutic effect was determined according to the Response Evaluation Criteria In Solid Tumors criteria (ver.1.1). The patients exhibited a lenvatinib response rate of 17.4% and a disease control rate of 43.5%. However, lenvatinib was associated with a 100% incidence of treatment-related adverse events (AEs), with hypertension being the most common AE (91.3%). Additionally, dose interruptions and reductions were required due to the development of tumor fistulas or other tumor-related AEs, and 9 (39.1%) patients discontinued treatment due to grade 3 or higher AEs. The median OS time was 166 days. Overall, the present study demonstrated the effectiveness of lenvatinib against ATC, which is often chemotherapy-resistant. Successful treatment of fistulas developing due to tumor necrosis at the site of the primary lesion is crucial for improving the patient outcome. The response to lenvatinib in patients with ATC varies on a case-by-case basis and requires further investigation in future studies.

Use of aspirin to reduce risk of initial vascular events in patients at moderate risk of cardiovascular disease (ARRIVE): a randomised, double-blind, placebo-controlled trial

The use of aspirin in the primary prevention of cardiovascular events remains controversial. We aimed to assess the efficacy and safety of aspirin versus placebo in patients with a moderate estimated risk of a first cardiovascular event. ARRIVE is a randomised, double-blind, placebo-controlled, multicentre study done in seven countries. Eligible patients were aged 55 years (men) or 60 years (women) and older and had an average cardiovascular risk, deemed to be moderate on the basis of the number of specific risk factors. We excluded patients at high risk of gastrointestinal bleeding or other bleeding, or diabetes. Patients were randomly assigned (1:1) with a computer-generated randomisation code to receive enteric-coated aspirin tablets (100 mg) or placebo tablets, once daily. Patients, investigators, and others involved in treatment or data analysis were masked to treatment allocation. The primary efficacy endpoint was a composite outcome of time to first occurrence of cardiovascular death, myocardial infarction, unstable angina, stroke, or transient ischaemic attack. Safety endpoints were haemorrhagic events and incidence of other adverse events, and were analysed in the intention-to-treat population. This study is registered with ClinicalTrials.gov, number NCT00501059. Between July 5, 2007, and Nov 15, 2016, 12 546 patients were enrolled and randomly assigned to receive aspirin (n=6270) or placebo (n=6276) at 501 study sites. Median follow-up was 60 months. In the intention-to-treat analysis, the primary endpoint occurred in 269 (4·29%) patients in the aspirin group versus 281 (4·48%) patients in the placebo group (hazard ratio [HR] 0·96; 95% CI 0·81-1·13; p=0·6038). Gastrointestinal bleeding events (mostly mild) occurred in 61 (0·97%) patients in the aspirin group versus 29 (0·46%) in the placebo group (HR 2·11; 95% CI 1·36-3·28; p=0·0007). The overall incidence rate of serious adverse events was similar in both treatment groups (n=1266 [20·19%] in the aspirin group vs n=1311 [20·89%] in the placebo group. The overall incidence of adverse events was similar in both treatment groups (n=5142 [82·01%] vs n=5129 [81·72%] in the placebo group). The overall incidence of treatment-related adverse events was low (n=1050 [16·75%] vs n=850 [13·54%] in the placebo group; p<0·0001). There were 321 documented deaths in the intention-to-treat population (n=160 [2·55%] vs n=161 [2·57%] of 6276 patients in the placebo group). The event rate was much lower than expected, which is probably reflective of contemporary risk management strategies, making the study more representative of a low-risk population. The role of aspirin in primary prevention among patients at moderate risk could therefore not be addressed. Nonetheless, the findings with respect to aspirin's effects are consistent with those observed in the previously published low-risk primary prevention studies. Bayer.

Phase III safety study of intravenous NEPA: a novel fixed antiemetic combination of fosnetupitant and palonosetron in patients receiving highly emetogenic chemotherapy

BackgroundNEPA, an oral fixed combination of the NK1RA netupitant (300mg) and clinically/pharmacologically distinct 5-HT3RA palonosetron (PALO, 0.50mg), is the first fixed antiemetic combination to have been approved. A single oral NEPA capsule plus dexamethasone (DEX) given before anthracycline–cyclophosphamide (AC) and non-AC highly emetogenic chemotherapy (HEC) showed superior prevention of chemotherapy-induced nausea and vomiting (CINV) over PALO plus DEX for 5days postchemotherapy. The safety of NEPA was well-established in the phase II/III clinical program in 1169 NEPA-treated patients. An intravenous (i.v.) formulation of the NEPA combination (fosnetupitant 235mg plus PALO 0.25mg) has been developed. Patients and methodsThis randomized, multinational, double-blind, stratified (by sex and country) phase III study (NCT02517021) in chemotherapy-naïve patients with solid tumors assessed the safety of a single dose of i.v. NEPA infused over 30min before initial and repeated cycles of HEC. Patients received either i.v. NEPA or oral NEPA, both with oral DEX on days 1–4. Safety was assessed primarily by treatment-emergent adverse events (AEs) and electrocardiograms. ResultsA total of 404 patients completed 1312 cycles. The incidence and type of treatment-emergent AEs were similar for both treatment groups with the majority of AEs as mild/moderate in intensity. There was no increased incidence of AEs in subsequent cycles in either group. The incidence of treatment-related AEs was similar and relatively low in both groups (12.8% i.v. NEPA and 11.4% oral NEPA during the entire study), with constipation being the most common (6.4% i.v. NEPA, 6.0% oral NEPA). No serious treatment-related AEs occurred in either group. No infusion site or anaphylactic reactions related to i.v. NEPA occurred. No clinically relevant changes in QTc and no cardiac safety concerns were observed. ConclusionsIntravenous NEPA was well-tolerated with a similar safety profile to oral NEPA in patients with various solid tumors receiving HEC.

Network meta-analysis of treatment regimens for inoperable advanced hepatocellular carcinoma with portal vein invasion.

PurposeWe assessed the efficacy and safety of different modalities using the network meta-analysis for inoperable hepatocellular carcinoma (HCC) with portal vein invasion. The interested modalities included stereotactic body radiotherapy (SBRT) combined with transarterial chemoembolization (TACE), three-dimensional radiotherapy (3D-RT) combined with hepatic arterial infusion chemotherapy (HAIC) or TACE, TACE plus sorafenib, and use of SBRT, HAIC, sorafenib, and TACE alone.MethodsPubMed and Cochrane Library electronic databases were systematically searched for eligible studies published up to June 2017. We used network meta-analysis to compare the disease control rate (DCR) and severe adverse events for the eight interested regimens included in this analysis. Study quality was assessed following the Grading of Recommendations, Assessment, Development and Evaluations method.ResultsFifteen studies published between 2010 and 2016 involving a total of 2,359 patients were enrolled in this network meta-analysis. With indirect comparison of DCR and overall safety, the pooled results showed that RT plus HAIC was the most effective regimen in treating advanced HCC with portal vein tumor thrombosis, followed by RT plus TACE. HAIC alone and sorafenib combined with HAIC appeared least effective intervention regimens. The incidence of treatment-related adverse events of grade 3 or 4 occurred less in the patients who received SBRT alone compared with other interested regimens.Conclusion3D-RT combined with HAIC or TACE showed more favorable treatment responses compared with other regimens in advanced HCC patients with portal vein tumor thrombosis.

Clinical outcomes of African American patients with advanced or metastatic non-small cell lung cancer on Nivolumab in a single community-based cancer center.

African Americans (AA) have the highest incidence and mortality rates with lung cancer. They are diagnosed at an earlier age with more advanced disease. Programmed cell death protein-1 inhibitor, Nivolumab, was approved as a second-line agent after failure of platinum-based therapy for advanced or metastatic non-small cell lung cancer (NSCLC). The original studies leading to the approval of Nivolumab had insufficient AA patients, thus there is still inadequate knowledge on treatment outcomes among AA patients. Our primary study endpoints were to determine the median overall survival, 1-year overall survival rate, median progression-free survival, and 1-year progression-free survival rate of patients with advanced or metastatic non-small cell lung cancer on Nivolumab. Our secondary study endpoints were to determine the overall tumor response rate, median time to response, median duration of response, and incidence of treatment-related adverse events of grade 3 or 4. In this retrospective study, we reviewed the charts of 38 patients, 29 of which were AA, with advanced or metastatic NSCLC who received Nivolumab from March 1, 2015 until November 30, 2017 from a single community-based cancer center and compared our results with historical data. Adenocarcinoma was the most common histology (71%) among all patients. Seven (18%) continued to use Nivolumab while 21 (55%) discontinued the treatment mainly due to progression of the disease. The median overall survival was 21.4months (95% CI 13.5-27.4) and 17.6months (95% CI 11.5-27.6) for all the patients and AA, respectively. Both have statistically significant difference (P < 0.001) compared to the historical studies of Borghaei et al. and Brahmer et al. At 1 year, the overall survival rate was 73% (95% CI 50-86) and 66% (95% CI 40-82) for all patients and AA, respectively. The median progression-free survival was also statistically significant (P < 0.001) between all the patients 6.3months (95% CI 2.8-8), AA 6.0months (95% CI 2.3-8.0), and the said historical studies. The 1-year progression-free survival rate was 23% (95% CI 10-39) and 28% (95% CI 12-47) for all patients and AA, respectively. Overall tumor response rate which includes complete and partial responses was 21% (95% CI 10-37) and 24% (95% CI 10-43) for all patients and AA, respectively. The median time to response was 3 and 2.8months for all patients and AA, respectively. The median duration of response was 3.8 and 4.0months for all patients and AA, respectively. Treatment-related adverse events of grade 3 or 4 were reported in 8 and 10% in all patients and AA, respectively, similar to the rates previously shown. AA patients with advanced or metastatic NSCLC on Nivolumab had increased overall survival and progression-free survival with similar grade 3 or 4 treatment-related adverse events. Providing adequate access to immunotherapy is indispensable to maximize survival benefit for AA patients.

Safety and Antitumor Activity of Pembrolizumab in Patients with Estrogen Receptor–Positive/Human Epidermal Growth Factor Receptor 2–Negative Advanced Breast Cancer

Purpose: We investigated the safety and antitumor activity of the anti-programmed death 1 monoclonal antibody pembrolizumab in patients with estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer with programmed death ligand 1-positive (PD-L1-positive) tumors in the phase Ib open-label, multicohort KEYNOTE-028 (NCT02054806) study.Patients and Methods: Patients with ER+/HER2- advanced breast cancer with PD-L1-positive tumors (combined positive score ≥1) received pembrolizumab (10 mg/kg every 2 weeks) up to 2 years or until confirmed progression/intolerable toxicity. Primary endpoints were safety and overall response rate (ORR), based on Response Evaluation Criteria in Solid Tumors, version 1 (RECIST v1.1) as assessed by investigator review.Results: Between April 2014 and January 2015, 25 patients were enrolled. Median number of prior therapies for breast cancer, including endocrine agents, was 9 (range, 3-15). Median follow-up was 9.7 months (range, 0.7-31.8 months). Three patients experienced partial response (PR) and none experienced complete response (CR), resulting in an ORR of 12.0% (95% CI, 2.5%-31.2%); 16% of patients had stable disease (SD) and clinical benefit rate (CR + PR + [SD for ≥24 weeks]) was 20% (95% CI, 7-41). Median duration of response was 12.0 months (range, 7.4-15.9 months). The incidence of treatment-related adverse events was 64%; nausea (20%) and fatigue (12%) were most common and were predominantly grade 1/2. No treatment-related discontinuations or deaths occurred.Conclusions: Pembrolizumab was well tolerated with modest but durable overall response in certain patients with previously treated, advanced, PD-L1-positive, ER+/HER2- breast cancer.

BAY 81-8973, a full-length recombinant factor VIII for the treatment of hemophilia A: product review

BAY 81-8973 (Kovaltry®) is an unmodified, full-length recombinant factor VIII (rFVIII) approved for the prevention and treatment of bleeding episodes in patients with hemophilia A. The amino acid sequence for BAY 81-8973 is identical to that of sucrose-formulated rFVIII (rFVIII-FS; Kogenate® FS/KOGENATE®, Bayer), but the two products differ in their manufacturing approaches. The manufacture of BAY 81-8973 includes several modifications and enhancements, such as the introduction of the gene for human heat shock protein 70, a molecular chaperone protein that facilitates folding of proteins; no addition of human- or animal-derived proteins in the cell culture, purification process, or final formulation; and use of a 20-nm filter to remove any potential aggregates and pathogens. BAY 81-8973 was extensively studied in the LEOPOLD clinical development program, which enrolled participants of all age groups (children, adolescents, and adults) with severe hemophilia A. The pharmacokinetic profile of BAY 81-8973 was shown to be noninferior to, and for some variables more favorable than, rFVIII-FS and another commercial full-length rFVIII product. BAY 81-8973 was shown to be efficacious when used for prophylaxis, on-demand treatment, and perioperative hemostasis. The efficacious prophylaxis dose of BAY 81-8973 was approximately 20-40 IU/kg given two or three times per week, which achieved low annualized bleeding rates. Either the one-stage or the chromogenic assay provides accurate measurements for postinfusion monitoring of BAY 81-8973 levels, with no product-specific calibration standard needed. The incidence of treatment-related adverse events was ⩽7% across all LEOPOLD studies, and no previously treated patient developed anti-BAY 81-8973 inhibitors in the completed primary studies.

Efficacy and safety of febuxostat extended release and immediate release in patients with gout and moderate renal impairment: phase II placebo-controlled study

BackgroundFebuxostat immediate release (IR), a xanthine oxidase inhibitor, is indicated for the management of hyperuricemia in patients with gout by lowering urate levels. An extended release (XR) formulation of febuxostat was developed to provide equal or superior efficacy on urate lowering compared with the IR formulation and potentially lower the risk of treatment-initiated gout flares due to an altered pattern of drug exposure. The present study evaluated the efficacy and safety of febuxostat XR and IR formulations in patients with gout and moderate renal impairment (estimated glomerular filtrate rate ≥ 30 and < 60 ml/min).MethodsThis was an exploratory, 3-month, phase II, multicenter, placebo-controlled, double-blind proof-of-concept study. Patients (n = 189) were randomized 1:1:1:1:1 to receive placebo or febuxostat IR 40 mg, XR 40 mg, IR 80 mg, or XR 80 mg once daily. Endpoints included: proportion of patients with serum uric acid (sUA) < 5.0 mg/dl at month 3 (primary endpoint), proportion of patients with sUA < 6.0 mg/dl at month 3, and proportion of patients with ≥ 1 gout flare requiring treatment over 3 months.ResultsAt month 3, all febuxostat treatment groups were associated with greater proportions of patients achieving sUA < 5.0 mg/dl (p < 0.05 vs placebo). A greater proportion of patients receiving XR 40 mg achieved sUA < 5.0 mg/dl versus those receiving IR 40 mg (p = 0.034); proportions were similar in the IR 80 mg and XR 80 mg groups. Higher proportions of febuxostat-treated patients achieved sUA < 6.0 mg/dl at month 3 (p < 0.05 vs placebo) and experienced ≥ 1 gout flare (significant for all comparisons, except XR 40 mg). Incidences of treatment-related adverse events were low across all treatment groups; the majority were mild or moderate with no apparent trends correlating with IR or XR doses. The most common treatment-emergent adverse event was hypertension. One death (unrelated to the study drug) was reported.ConclusionsThese exploratory data demonstrate that febuxostat (XR and IR) formulations were effective and well tolerated in patients with gout and moderate renal impairment.Trial registrationClinicalTrials.gov, NCT02128490 Registered on 29 April 2014.

Systematic clinical evidence review of NASHA (Durolane hyaluronic acid) for the treatment of knee osteoarthritis.

BackgroundPain and limitations in joint mobility associated with knee osteoarthritis (OA) are clinically challenging to manage, and advanced progression of disease can often lead to total knee arthroplasty. Intra-articular injection of hyaluronic acid (HA), also referred to as viscosupplementation, is a non-surgical treatment approach for OA, the effectiveness of which may depend on the HA composition, and the length of time over which it resides in the joint. One of the available options for such therapies includes NASHA (Durolane HA), a non-animal, biofermentation-derived product, which is manufactured using a process that stabilizes the HA molecules to slow down their rate of degradation and produce a unique formulation with a terminal half-life of ~1 month. The objectives of the current review were to assess, in patients with OA of the knee, the efficacy and safety of intra-articular treatment with NASHA relative to control (saline) injections, other HA products, and other injectables (corticosteroids, platelet-rich plasma, mesenchymal stem cells).MethodsThis systematic evidence review examines patient outcomes following NASHA treatment as described in published data from studies conducted in subjects with knee OA. A Preferred Reporting Items for Systematic Reviews and Meta-analyses-compliant literature search strategy yielded 11 eligible clinical studies with a variety of comparator arms. Outcomes assessed at various time points following intra-articular treatment included measures of pain, function, quality of life, and incidence of treatment-related adverse events (AEs).ResultsThe available evidence reported for the clinical studies assessed demonstrates sustained and effective relief of knee OA symptoms following a single injection of NASHA. In addition, an excellent biocompatibility profile is observed for NASHA as an intra-articular therapy for OA, as reflected by the low rate of AEs associated with treatment.ConclusionTreatment with NASHA is an effective and safe single-injection procedure, which can be beneficial in the clinical management of knee OA.

The use of a novel non-steroidal mineralocorticoid receptor antagonist finerenone for the treatment of chronic heart failure: A systematic review and meta-analysis.

Background:The non-steroidal mineralocorticoid receptor antagonist finerenone (BAY 94–8862) has been used to treat chronic heart failure (CHF) with reduced ejection fraction (HFrEF). However, conflicting results were reported for its efficacy and safety. The study aimed to compare the efficacy and safety of finerenone versus spironolactone or eplerenone in patients with chronic heart failure.Methods:Electronic databases including MEDLINE, EMBASE, and CENTRAL were searched from inception to December 2017 for randomized controlled trials assessing finerenone treatment in patients with chronic heart failure. Data concerning the study's design, patients’ characteristics, and outcomes were extracted. Risk ratio (RR) and mean differences (MD) were calculated using either fixed or random effects models.Results:Three trials with 1520 CHF patients were included in the systematic review. In terms of anti-ventricular remodeling, we calculated the effective number of cases with a 30% reduction in NT-proBNP. Finerenone was equivalent to the existing steroidal mineralocorticoid antagonist (P < .05). However, the efficacy of finerenone appeared to be dose-dependent. At a dose of 10 mg/d finerenone was found to be marginally better than that of steroidal mineralocorticoid receptor antagonists (MRAs) (RR = 1.18, 95% confidence interval [CI] 0.88, 1.57, P > .05). The incidence of treatment-related adverse events (TEAEs) of finerenone at 10 mg/d was significantly lower than 25 to 50 mg/d of steroidal MRAs (RR = 0.81, 95% CI = 0.66–0.99, P = .04). Moreover, the serum potassium levels in the finerenone 10 mg/d group were lower than those in the 25 to 50 mg/d steroidal MRAs group (MD = –0.14, 95% CI –0.30–0.02, P = .09), whereas the estimated glomerular filtration rate (eGFR) was higher in finerenone versus steroidal MRAs treated patients (MD = 2.07, 95% CI –0.04–4.17, P = .05).Conclusions:Finerenone reduced NT-proBNP level, urinary albumin/creatinine ratio (UACR), and other biochemical indicators, in a dose-dependent manner. In terms of anti-ventricular remodeling in patient with chronic heart failure, finerenone at 10 mg/d is as effective as 20 to 50 mg/d of steroidal MRAs. However, finerenone is much safer to patients with chronic kidney disease.

Safety of a novel intranasal formulation of azelastine hydrochloride and fluticasone propionate in children: A randomized clinical trial.

The safety of a novel intranasal formulation of azelastine hydrochloride (AZE) and fluticasone propionate (FP) has been established in adults and adolescents with allergic rhinitis but not in children <12 years old. To evaluate the safety and tolerability of an intranasal formulation of AZE and FP in children ages 4-11 years with allergic rhinitis. The study was a randomized, 3-month, parallel-group, open-label design. Qualified patients were randomized in a 3:1 ratio to AZE/FP (n = 304) or fluticasone propionate (FP) (n = 101), one spray per nostril twice daily, and to one of three age groups: ≥4 to <6 years, ≥6 to <9 years, and ≥9 to <12 years. Safety was assessed by child- or caregiver-reported adverse events, nasal examinations, vital signs, and laboratory assessments. The incidence of treatment-related adverse events (TRAEs) was low in both the AZE/FP (16%) and FP-only (12%) groups after 90 days' continuous use. Epistaxis was the most frequently reported TRAE in both groups (AZE/FP, 9%; FP, 9%), followed by headache (AZE/FP, 3%; FP, 1%). All other TRAEs in the AZE/FP group were reported by ≤1% of the children. The majority of TRAEs were of mild intensity and resolved spontaneously. Results of nasal examinations showed an improvement over time in both groups, with no cases of mucosal ulceration or nasal septal perforation. There were no unusual or unexpected changes in laboratory parameters or vital signs. The intranasal formulation of AZE and FP was safe and well tolerated after 3 months' continuous use in children with allergic rhinitis.The study was registered on <ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://ClinicalTrials.gov">ClinicalTrials.gov</ext-link> (NCT01794741).

Multiple Antigen Stimulating Cellular Therapy (MASCT) For Hepatocellular Carcinoma After Curative Treatment: A Retrospective Study.

Background & Aims: The prognosis of hepatocellular carcinoma (HCC) remains poor and available treatment options are limited. This retrospective study evaluated the efficacy of Multiple Antigen Stimulating Cell Therapy (MASCT) as an adjuvant therapy for the treatment of HCC after curative treatment.Methods: Patients who underwent HCC curative treatments were classified into two groups: the MASCT group, in which patients received MASCT treatment after curative treatment (n = 47), and the control group, in which patients did not receive any treatment after curative treatment (n = 99). Patients who received ≥ 5 courses of MASCT treatment before recurrence or death (n = 26) were further stratified into a subgroup (multiple-course MASCT group) for analysis. The primary endpoint was overall survival (OS). The secondary endpoints were disease-free survival (DFS) and safety.Results: Kaplan-Meier analysis showed no statistically significant difference in OS between the MASCT group and the control group (P = 0.132), nor in DFS (P = 0.310) (median: 36.17 vs. 24.27 months). However, when comparing the multiple-course MASCT treated group to the control group, Kaplan-Meier analysis showed a significant difference in OS (P = 0.011), but not in DFS (P = 0.104) (median: 47.10 vs. 24.27 months). The overall incidences of treatment-related adverse events in the MASCT group and control group were 14.89% (7/47) and 19.19% (19/99), respectively. No MASCT treatment-related serious adverse events were reported.Conclusions: Although the MASCT group was not associated with significantly longer OS or DFS, the multiple-course MASCT group showed significantly improved overall survival after curative treatment, and the treatment procedures were well-tolerated. Multiple-course MASCT may therefore provide another choice for patients with HCC after curative treatment.

Catheter-based endobronchial electroporation is feasible for the focal treatment of peribronchial tumors

ObjectiveTo evaluate the feasibility of catheter-based endobronchial electroporation for the treatment of peribronchial tumors and assess the incidence of treatment-related adverse events. MethodsCytotoxicity of electroporation with or without cisplatin or gefitinib was assessed in vitro with lung cancer and normal cell lines. A novel catheter was designed for endobronchial electroporation, and computer simulations were used to predict in vivo treatment effects. Electroporation with the test catheter was performed (2000 V, 70 pulses) in the main bronchus of 8 pigs at 11 locations. Computed tomography imaging was performed before they were killed at 4 hours (6 animals) or 4 weeks (2 animals) posttreatment. Treated airway and surrounding parenchyma were compared with sham treatment via gross and histopathology. ResultsSignificant cell death due to electroporation and increased cytotoxicity in combination with cisplatin or gefitinib were observed in cancer cells only (P < .05). Simulations predicted penetrative electroporation of peribronchial parenchyma without tissue heating. Electric pulse delivery in vivo induced transient venous and bronchial spasms that resolved without intervention. Cross-sectional measurement of electroporation effects on computed tomography (14.4 ± 1.4 by 10.5 ± 1.3 mm) and gross pathology (17.2 ± 3.0 by 8.8 ± 0.6 mm) were representative of values predicted by simulation (P < .001). Cell death due to irreversible electroporation was observed in bronchial and parenchymal tissue in acute tissue samples. Treated lung rapidly recovered from the effects of electroporation without change in bronchial patency at 4 weeks posttreatment. ConclusionsCatheter-based endobronchial electroporation is a reproducible technique that can be used to treat peribronchial tumors in combination with cisplatin, without affecting patency of the treated bronchus.

Efficacy and safety of fesoterodine treatment for overactive bladder symptoms in elderly women with and without hypertension.

To assess fesoterodine treatment in elderly women with overactive bladder with and without hypertension. Data for 2527 elderly women with overactive bladder symptoms, including urgency urinary incontinence, were pooled from 10 double-blind, placebo-controlled fesoterodine studies. A total of 1523 elderly women (60.3%) had a history of hypertension, and 1004 women (39.7%) had no hypertension history. Overactive bladder symptoms, mean bodyweight and mean body mass index at baseline were significantly higher in women with overactive bladder and hypertension versus those without hypertension (P<0.05). Statistically significant improvements in overactive bladder symptoms at week12 were observed for fesoterodine treatment versus placebo in women with hypertension and those without (P<0.05). The diary-dry rate (no urgency urinary incontinence episodes), the proportion with less than eight micturitions/24h, overactive bladder symptom bother and health-related quality of life were also statistically significantly improved by fesoterodine treatment in both populations. Incidence of treatment-related adverse events with fesoterodine was similar in women with hypertension (39.3%) and without hypertension (44.6%). Dry mouth and constipation were the most common treatment-related adverse events with fesoterodine in women with hypertension (26.2% and 5.2%, respectively) and without hypertension (30.5% and 8.0%). A relationship among the severity of overactive bladder symptoms, hypertension and obesity in elderly women is suggested. Fesoterodine provides significantly greater improvements in overactive bladder symptoms and health-related quality of life versus placebo in women with or without hypertension. Hypertension does not appear to affect the efficacy and safety of fesoterodine in elderly women with overactive bladder symptoms, including urgency urinary incontinence.

Pharmacokinetics and Safety of a Single Oral Dose of Mirogabalin in Japanese Subjects With Varying Degrees of Renal Impairment.

Mirogabalin (DS‐5565) is a novel preferentially selective α2δ‐1 ligand being developed for the treatment of diabetic peripheral neuropathic pain and postherpetic neuralgia. The current multicenter open‐label study determined the effect of varying degrees of renal impairment on the pharmacokinetics and safety of a single dose of mirogabalin 5 mg in Japanese subjects. A total of 30 subjects (6 subjects per renal function category [normal, mild, moderate, or severe impairment; and end‐stage renal disease (ESRD)]) were enrolled and completed the study. The AUClast increased with severity of renal impairment; the geometric least‐squares mean ratios of AUClast compared with subjects with normal renal function were 1.3, 1.9, 3.6, and 5.3 for patients with mild, moderate, and severe impairment and ESRD, respectively. In accordance with this AUClast increase, apparent total body clearance (CL/F), renal clearance (CLr), and the cumulative percentage of mirogabalin dose excreted into urine all decreased with severity of renal impairment. There were no deaths and no severe treatment‐related adverse events (TEAEs), serious TEAEs, or TEAEs resulting in study discontinuation. Mirogabalin was well tolerated in Japanese subjects with normal renal function and those with mild to severe renal impairment. It was also tolerated in subjects with ESRD but with a higher incidence of TEAEs. The most frequently reported TEAEs were dizziness (ESRD, n = 3), somnolence (ESRD, n = 2), and vomiting (ESRD, n = 2). Based on these data, a mirogabalin dose adjustment will be considered in Japanese subjects with moderate to severe renal impairment and those with ESRD.

Effect of Electroacupuncture on Urinary Leakage Among Women With Stress Urinary Incontinence: A Randomized Clinical Trial.

Electroacupuncture involving the lumbosacral region may be effective for women with stress urinary incontinence (SUI), but evidence is limited. To assess the effect of electroacupuncture vs sham electroacupuncture for women with SUI. Multicenter, randomized clinical trial conducted at 12 hospitals in China and enrolling 504 women with SUI between October 2013 and May 2015, with data collection completed in December 2015. Participants were randomly assigned (1:1) to receive 18 sessions (over 6 weeks) of electroacupuncture involving the lumbosacral region (n = 252) or sham electroacupuncture (n = 252) with no skin penetration on sham acupoints. The primary outcome was change from baseline to week 6 in the amount of urine leakage, measured by the 1-hour pad test. Secondary outcomes included mean 72-hour urinary incontinence episodes measured by a 72-hour bladder diary (72-hour incontinence episodes). Among the 504 randomized participants (mean [SD] age, 55.3 [8.4] years), 482 completed the study. Mean urine leakage at baseline was 18.4 g for the electroacupuncture group and 19.1 g for the sham electroacupuncture group. Mean 72-hour incontinence episodes were 7.9 for the electroacupuncture group and 7.7 for the sham electroacupuncture group. At week 6, the electroacupuncture group had greater decrease in mean urine leakage (-9.9 g) than the sham electroacupuncture group (-2.6 g) with a mean difference of 7.4 g (95% CI, 4.8 to 10.0; P < .001). During some time periods, the change in the mean 72-hour incontinence episodes from baseline was greater with electroacupuncture than sham electroacupuncture with between-group differences of 1.0 episode in weeks 1 to 6 (95% CI, 0.2-1.7; P = .01), 2.0 episodes in weeks 15 to 18 (95% CI, 1.3-2.7; P < .001), and 2.1 episodes in weeks 27 to 30 (95% CI, 1.3-2.8; P < .001). The incidence of treatment-related adverse events was 1.6% in the electroacupuncture group and 2.0% in the sham electroacupuncture group, and all events were classified as mild. Among women with stress urinary incontinence, treatment with electroacupuncture involving the lumbosacral region, compared with sham electroacupuncture, resulted in less urine leakage after 6 weeks. Further research is needed to understand long-term efficacy and the mechanism of action of this intervention. clinicaltrials.gov Identifier: NCT01784172.

AbobotulinumtoxinA: A Review in Pediatric Lower Limb Spasticity.

AbobotulinumtoxinA (Dysport®) is currently the only botulinum toxin A formulation approved by the US FDA for the treatment of lower limb spasticity in pediatric patients aged ≥2 years. Intramuscular abobotulinumtoxinA was approved based on the results of a pivotal phase 3 trial in children with lower limb spasticity due to cerebral palsy. In this trial, a single treatment cycle with abobotulinumtoxinA 10-15 U/kg/leg injected into the gastrocnemius and soleus muscles significantly improved ankle plantar flexor muscle tone (primary endpoint), with abobotulinumtoxinA recipients showing a significant response to treatment relative to placebo. AbobotulinumtoxinA treatment also improved spasticity grade. The improvements in muscle tone and spasticity were associated with an improved ability to attain functional goals. Clinical benefits of abobotulinumtoxinA treatment lasted for 16-22 weeks in most patients, and were maintained with multiple treatment cycles during 1 year in an open-label extension study. AbobotulinumtoxinA was generally well tolerated, with a relatively low incidence of treatment-related adverse events. In summary, abobotulinumtoxinA is an effective and generally well tolerated treatment option for children with lower limb spasticity.

Phase 2 study to evaluate safety and efficacy of MEDI4736 (durvalumab [DUR]) in glioblastoma (GBM) patients: An update.

2042 Background: DUR is a human IgG1 monoclonal Ab against PD-L1. PD-1/PD-L1 blockade has shown benefit in solid tumors. PD-L1 is expressed by many GBM tumors while cytotoxic lymphocytes infiltrating GBM tumors often express PD-1; thus, there is a rationale for exploring PD-1/PD-L1 blockade in GBM. Bevacizumab (BEV) is a VEGF-specific angiogenesis inhibitor approved for recurrent GBM. PD-L1 blockade and angiogenesis inhibition may be synergistic. Methods: This ongoing Phase 2, multicenter, open-label study (NCT02336165) evaluates safety/efficacy of DUR (10 mg/kg every 2 wks) in 5 GBM cohorts. Secondary endpoints are safety/tolerability, median PFS/OS, overall response rate and quality of life measures. Exploratory endpoints: neurologic function and immunocorrelative biomarkers. Results: Enrollment as of 16 Dec 2016: Cohort A = 35, B = 31, B2 = 34, B3 = 34, and C = 20 pts. Enrollment is ongoing for Cohorts A and C. This is an update to the interim analysis that was reported for Cohort B (male: 83.9%; mean age: 54.0 [24-77] years; baseline ECOG PS0: 51.6%, PS1: 48.4%; baseline measurable lesions: 77.4%). Incidences of treatment-related adverse events (TRAEs) by max CTCAE grade (Gr) were Gr1: 35.5%; Gr2: 41.9%; Gr3: 9.7%; and Gr4/5: 0%. Most common TRAEs (≥3 pts): fatigue, headache, hemiparesis, gait disturbance, increased AST, and decreased platelets/WBCs/lymphs. Six of 30 evaluable pts were progression free at 6 months (Kaplan-Meier, 20.0% [90% CI: 9.7, 33.0]); best overall response: partial response, 4 (13.3%) pts and stable disease, 14 (46.7%). At 1 year, 4 pts remained progression free (longest PFS ongoing at 80 wks, n=2). OS-6 and OS-12 are 59.0 and 44.4%, respectively. As of 16 Dec 2016, 7 pts remain alive (longest OS ongoing at 86 wks). Conclusions: DUR monotherapy appears to be well tolerated and shows durable activity in a subset of BEV-naïve recurrent GBM pts. Study is ongoing. Clinical trial information: NCT02336165.

Nivolumab in patients with advanced hepatocellular carcinoma (CheckMate 040): an open-label, non-comparative, phase 1/2 dose escalation and expansion trial

For patients with advanced hepatocellular carcinoma, sorafenib is the only approved drug worldwide, and outcomes remain poor. We aimed to assess the safety and efficacy of nivolumab, a programmed cell death protein-1 (PD-1) immune checkpoint inhibitor, in patients with advanced hepatocellular carcinoma with or without chronic viral hepatitis. We did a phase 1/2, open-label, non-comparative, dose escalation and expansion trial (CheckMate 040) of nivolumab in adults (≥18 years) with histologically confirmed advanced hepatocellular carcinoma with or without hepatitis C or B (HCV or HBV) infection. Previous sorafenib treatment was allowed. A dose-escalation phase was conducted at seven hospitals or academic centres in four countries or territories (USA, Spain, Hong Kong, and Singapore) and a dose-expansion phase was conducted at an additional 39 sites in 11 countries (Canada, UK, Germany, Italy, Japan, South Korea, Taiwan). At screening, eligible patients had Child-Pugh scores of 7 or less (Child-Pugh A or B7) for the dose-escalation phase and 6 or less (Child-Pugh A) for the dose-expansion phase, and an Eastern Cooperative Oncology Group performance status of 1 or less. Patients with HBV infection had to be receiving effective antiviral therapy (viral load <100 IU/mL); antiviral therapy was not required for patients with HCV infection. We excluded patients previously treated with an agent targeting T-cell costimulation or checkpoint pathways. Patients received intravenous nivolumab 0·1-10 mg/kg every 2 weeks in the dose-escalation phase (3+3 design). Nivolumab 3 mg/kg was given every 2 weeks in the dose-expansion phase to patients in four cohorts: sorafenib untreated or intolerant without viral hepatitis, sorafenib progressor without viral hepatitis, HCV infected, and HBV infected. Primary endpoints were safety and tolerability for the escalation phase and objective response rate (Response Evaluation Criteria In Solid Tumors version 1.1) for the expansion phase. This study is registered with ClinicalTrials.gov, number NCT01658878. Between Nov 26, 2012, and Aug 8, 2016, 262 eligible patients were treated (48 patients in the dose-escalation phase and 214 in the dose-expansion phase). 202 (77%) of 262 patients have completed treatment and follow-up is ongoing. During dose escalation, nivolumab showed a manageable safety profile, including acceptable tolerability. In this phase, 46 (96%) of 48 patients discontinued treatment, 42 (88%) due to disease progression. Incidence of treatment-related adverse events did not seem to be associated with dose and no maximum tolerated dose was reached. 12 (25%) of 48 patients had grade 3/4 treatment-related adverse events. Three (6%) patients had treatment-related serious adverse events (pemphigoid, adrenal insufficiency, liver disorder). 30 (63%) of 48 patients in the dose-escalation phase died (not determined to be related to nivolumab therapy). Nivolumab 3 mg/kg was chosen for dose expansion. The objective response rate was 20% (95% CI 15-26) in patients treated with nivolumab 3 mg/kg in the dose-expansion phase and 15% (95% CI 6-28) in the dose-escalation phase. Nivolumab had a manageable safety profile and no new signals were observed in patients with advanced hepatocellular carcinoma. Durable objective responses show the potential of nivolumab for treatment of advanced hepatocellular carcinoma. Bristol-Myers Squibb.
