Open House: pm Public. Improvement of conspicuity of trailblazing signs, Phase III : evaluation of fluorescent colors. This report represents a Phase III effort to design and evaluate a new sign design for incident route trailblazing. The colors evaluated were fluorescent coral, fluorescent purple, fluorescent yellow-green, and non-fluorescent purple. The results ind Roberts, Barry C.

The amorphous blue phase III of cholesteric liquid crystals, also known as the "blue fog," are among the rising stars in materials science that can potentially be used to develop next-generation displays with the ability to compete toe-to-toe with disruptive technologies like organic light-emitting diodes. The structure and properties of the practically unobservable blue phase III have eluded scientists for more than a century since it was discovered.

This progress report reviews the developments in this field from both fundamental and applied research perspectives. The first part of this progress report gives an overview of the years-long scientific tour-de-force that very recently resulted in the revelation of the mysterious structure of blue phase III.

The second part reviews progress made in the past decade in developing electrooptical, optical, and photonic devices based on blue phase III. The strong and weak aspects of the development of these devices are underlined and criticized, respectively. The third- and-final part proposes ideas for further improvement in blue phase III technology to make it feasible for commercialization and widespread use.

KGaA, Weinheim. The development of monoclonal antibodies targeting IL and IL has enhanced the therapeutic options available for psoriasis patients. Recent research suggests that IL alone plays a role in the pathogenesis of psoriasis. The objective was to review the phase III clinical trial data for the anti-IL agents to evaluate the safety and efficacy profile of each agent. We reviewed the results of the phase III clinical trials for the anti-IL agents tildrakizumab and guselkumab. The results of phase III trials on risankizumab have not yet been reported. The safety profiles of the agents were comparable, with the most commonly reported adverse events of nasopharyngitis and upper respiratory tract infections.

The anti-IL agents demonstrated a rapid clinical improvement that is similar or superior to the improvement seen with currently marketed IL inhibitors with a favourable short-term safety profile. The results of the phase III trials support the notion that IL is a potential target in psoriasis treatment.

Blackstock Joseph O December 4. The purpose of this study was to examine the effects of PECS phase III application training on independent mands in young children with autism. Participants were five children with autism ranging from ages 2 to 4 years old.

This new report is that appendix broken out as a standalone document to assist utilities in recruiting and developing Secure Power Systems Professionals at their site. As opposed to describing the findings from the study that was conducted, it provides a tool-kit that can be used by Oklahoma principals and teachers to determine the best courses of action for their schools and classrooms.

This is a report on the third phase of Project IN-STEP, which was intended to develop a viable model for individualized, multi-media in-service teacher education programs. The rationale for Phase III was to see if the model could be successfully transferred to an area other than teaching…. These latter types of studies are usually carried out concurrently with Phase III studies.

This progression continues into the post-marketing period Phase IV with surveillance of long term efficacy and observational studies of possible rare adverse events to establish "safety" with more confidence. This paper examines, in general, the aims and designs of studies in each phase as an introduction to the more specific publications that follow. Analysis of phase II studies on targeted agents and subsequent phase III trials: what are the predictors for success? To identify the characteristics of phase II studies that predict for subsequent "positive" phase III trials those that reached the proposed primary end points of study or those wherein the study drug was superior to the standard regimen investigating targeted agents in advanced tumors.

We identified all phase III clinical trials of targeted therapies against advanced cancers published from to Characteristics of the preceding phase II studies were reviewed to identify predictive factors for success of the subsequent phase III trial. Data were analyzed using the chi 2 test and logistic regression models. Of phase II studies, Phase II studies from multiple rather than single institutions were more likely to precede a successful trial The percentage of successful trials from pharmaceutical companies was significantly higher compared with academic, cooperative groups, and research institutes On multivariate analysis, these factors and shorter time interval between publication of phase II results and III study publication were independent predictive factors for a positive phase III trial.

In phase II studies of targeted agents, multiple- versus single-institution participation, positive phase II trial, pharmaceutical company-based trials, and shorter time period between publication of phase II to phase III trial were independent predictive factors of success in a phase III trial. Investigators should be cognizant of these factors in phase II studies before designing phase III trials.

Perampanel is a selective, noncompetitive AMPA receptor antagonist approved as adjunctive treatment for partial seizures. Electrocardiograms were recorded at baseline, Day 7 post 6 mg dose , and Day 16 post 12 mg dose. Statistical comparisons were between the highest approved perampanel dose 12 mg versus placebo, a "mid-therapeutic" dose 6 mg versus placebo, and moxifloxacin versus placebo.

Acknowledging that the Phase I thorough QT study could not incorporate a true "supratherapeutic" dose due to length of titration and tolerability concerns in healthy subjects, Phase III studies of perampanel included expanded electrocardiogram safety evaluations specifically intended to support concentration-QT response modeling.

Phase I, consisting of developing and implementing institutional controls at Operble Unit sites and developing and implementing Idaho National Laboratory Site-wide plans for both institutional controls and ecological monitoring, was addressed in a previous report. Phase IV will remediate hazards from unexploded ordnance.

Investor interest in gene therapy has increased substantially over the past few years, and the next major catalyst for the field is likely to be Spark Therapeutics's phase III trial for the treatment of visual impairment caused by RPE65 gene mutations often referred to as Leber congenital amaurosis type 2, or LCA2, but may include other retinal disorders. Analysis of the approach from the basic genetics, underlying visual mechanisms, clinical data, and commercialization considerations helps frame investor expectations and the potential implications for the broader field.

There is currently no standard of care for treatment of negative symptoms of schizophrenia, although some previous results with glutamatergic agonists have been promising. Three SunLyte [WN], DayLyte [WN], and FlashLyte [NN] phase III , multicenter, randomized, week, double-blind, parallel -group, placebo-controlled studies evaluated the efficacy and safety of adjunctive bitopertin in stable patients with persistent predominant negative symptoms of schizophrenia treated with antipsychotics. SunLyte met the prespecified criteria for lack of efficacy and was declared futile. Following a 4-week prospective stabilization period, patients were randomly assigned to bitopertin 5 mg and 10 mg [DayLyte] and 10 mg and 20 mg [FlashLyte] or placebo once daily for 24 weeks.

The primary efficacy end point was mean change from baseline in Positive and Negative Syndrome Scale negative symptom factor score at week The intent-to-treat population in DayLyte and FlashLyte included and patients, respectively. At week 24, mean change from baseline showed improvement in all treatment arms but no statistically significant separation from placebo in Positive and Negative Syndrome Scale negative symptom factor score and all other end points. Bitopertin was well tolerated.

These studies provide no evidence for superior efficacy of adjunctive bitopertin in any of the doses tested over placebo in patients with persistent predominant negative symptoms of schizophrenia. Published by Elsevier Inc. Efficacy and safety of 3-month dosing regimen of degarelix in Japanese subjects with prostate cancer: A phase III study. Non-inferiority in the cumulative castration rate of the 3-month formulation of degarelix compared with the 3-month formulation of goserelin was evaluated in subjects with prostate cancer.

A phase III , open-label, parallel -arm study was carried out. Non-inferiority in castration rate and safety of degarelix to goserelin were evaluated. The cumulative castration rate was Analyses indicated the non-inferiority of the 3-month formulation of degarelix to goserelin. Degarelix showed more rapid decreases in testosterone, luteinizing hormone, follicle stimulating hormone, and prostate-specific antigen levels compared with goserelin. The most common adverse events in the degarelix group were injection site reactions.

Non-inferiority of the 3-month formulation of degarelix to goserelin was shown for testosterone suppression. The 3-month formulation of degarelix was also found to be tolerated as an androgen deprivation therapy for patients with prostate cancer. This trial was registered with ClinicalTrials. Comparison of futility monitoring guidelines using completed phase III oncology trials. Futility inefficacy interim monitoring is an important component in the conduct of phase III clinical trials, especially in life-threatening diseases.

Desirable futility monitoring guidelines allow timely stopping if the new therapy is harmful or if it is unlikely to demonstrate to be sufficiently effective if the trial were to continue to its final analysis. There are a number of analytical approaches that are used to construct futility monitoring boundaries. The most common approaches are based on conditional power, sequential testing of the alternative hypothesis, or sequential confidence intervals. The resulting futility boundaries vary considerably with respect to the level of evidence required for recommending stopping the study.

We considered published superiority phase III trials with survival endpoints initiated after There are 52 studies available for this analysis from different disease sites. Total sample size and maximum number of events statistical information for each study were calculated using protocol-specified effect size, type I and type II error rates.

In addition to the common futility approaches, we considered a recently proposed linear inefficacy boundary approach with an early harm look followed by several lack-of-efficacy analyses. For each futility approach, interim test statistics were generated for three schedules with different analysis frequency, and early stopping was recommended if the interim result crossed a futility stopping boundary. For trials not demonstrating superiority, the impact of each rule is summarized as savings on sample size, study duration, and information time scales.

For negative studies, our results show that the futility approaches based on testing the alternative hypothesis. Bevacizumab in ovarian cancer: A critical review of phase III studies. Bevacizumab BV is a humanized monoclonal antibody targeting vascular endothelial growth factor and it is the first molecular-targeted agent to be used for the treatment of ovarian cancer OC.

Randomized Phase III trials evaluated the combination of BV plus standard chemotherapy for first-line treatment of advanced OC and for platinum-sensitive and platinum-resistant recurrent OC. These trials reported a statistically significant improvement in progression-free survival but not in overall survival. Furthermore, BV effectively improved the quality of life with regard to abdominal symptoms in recurrent OC patients.

Bevacizumab is associated with adverse events such as hypertension, bleeding, thromboembolism, proteinuria, delayed wound healing, and gastrointestinal events. However, most of these events can be adequately managed. This review describes the latest evidence for BV treatment of OC and selection of patients for personalized treatment. Spark Therapeutics recently reported positive phase III results for SPK-RPE65 targeting the treatment of visual impairment caused by RPE65 gene mutations often referred to as Leber congenital amaurosis type 2, or LCA2, but may include other retinal disorders , marking an important inflection point for the field of gene therapy.

The results highlight the ability to successfully design and execute a randomized trial of a gene therapy and also reinforce the potentially predictive nature of early preclinical and clinical data. The results are expected to pave the way for the first approved gene therapy product in the United States and should sustain investor interest and confidence in gene therapy for many approaches, including retina targeting and beyond. Intermittent androgen deprivation IAD has been widely tested in prostate cancer. Different design and conduct issues must be critically evaluated to better interpret the results.

Seven published phase III trials were examined for prespecified design and outcomes. Treatment specifications; primary end point; superiority versus noninferiority design assumptions, including magnitude of assumed versus observed noninferiority margin NIM ; duration of follow-up; and quality-of-life QOL outcomes were considered in terms of the results and conclusions reported.

Five trials had a superiority and three had a noninferiority primary hypothesis. Only three trials had a uniform population and overall survival OS end point. All trials observed better outcomes in terms of OS and progression-free survival PFS than assumed at time of study design, translating into prespecified NIMs or hazard ratios that reflected larger absolute differences in OS or PFS between arms.

Lower-than-expected event rates also reduced statistical power for the trials. Other factors, including length of follow-up, cause of death, QOL, and primary end point, and their impact on trial interpretation are discussed. Trials concluding IAD is noninferior to CAD were based on wide NIMs that included clinically important survival differences, not likely to be considered comparable by physicians or patients. Interim analyses relying on short follow-up and including a majority of non-prostate cancer deaths will favor a noninferiority conclusion and should be interpreted cautiously.

Adequate follow-up is required to ensure capture of prostate cancer deaths in both superiority and noninferiority trials. The probability of success or average power describes the potential of a future trial by weighting the power with a probability distribution of the treatment effect. The treatment effect estimate from a previous trial can be used to define such a distribution. During the development of targeted therapies, it is common practice to look for predictive biomarkers.

The consequence is that the trial population for phase III is often selected on the basis of the most extreme result from phase II biomarker subgroup analyses. In such a case, there is a tendency to overestimate the treatment effect. We investigate whether the overestimation of the treatment effect estimate from phase II is transformed into a positive bias for the probability of success for phase III. This simulation allows to investigate selection probabilities and allows to compare the estimated with the true probability of success.

We consider the estimated probability of success with and without subgroup selection. Depending on the true treatment effects, there is a negative bias without selection because of the weighting by the phase II distribution. In comparison, selection increases the estimated probability of success. Thus, selection does not lead to a bias in probability of success if underestimation due to the phase II distribution and overestimation due to selection cancel each other out. We recommend to perform similar simulations in practice to get the necessary information about the risk and chances associated with such subgroup selection designs.

Additionally, we present evidence for 1, novel pairwise relationships across 9 populations. Surprisingly, significant Cotterman's coefficients of relatedness K1 IBD1 values were detected between pairs of known parents. Furthermore, significant K2 IBD2 values were detected in 32 previously annotated parent-child relationships. Consistent with a hypothesis of inbreeding, regions of homozygosity ROH were identified in the offspring of related parents, of which a subset overlapped those reported in previous studies Gibson et al.

Finally, 8 previously annotated parent-child relationships had unexpected K0 IBD0 values resulting from a chromosomal abnormality or genotype error , and 10 previously annotated second-degree relationships along with 38 other novel pairwise relationships had unexpected IBD2 indicating two separate paths of recent ancestry.

These newly described types of relatedness may impact the outcome of previous studies and should inform the design of future studies relying on the HapMap Phase III resource. Quality of reporting of outcomes in phase III studies of pulmonary tuberculosis: a systematic review. Despite more than 60 years of clinical trials, tuberculosis TB still causes a high global burden of mortality and morbidity. Treatment currently requires multiple drugs in combination, taken over a prolonged period. New drugs are needed to shorten treatment duration, prevent resistance and reduce adverse events.

However, to improve on current methodology in drug development, a more complete understanding of the existing clinical evidence base is required. A systematic review was undertaken to summarise outcomes reported in phase III trials of patients with newly diagnosed pulmonary TB. Reference lists of included studies were also searched. This systematic review considered all reported outcomes. Of included studies, considered "on-treatment" outcomes whilst reported "off-treatment" outcomes.

There was wide variation and ambiguity in the definition of reported outcomes, including their relationship to treatment and in the time points evaluated. Additional challenges were observed regarding the analysis approach taken per protocol versus intention to treat and the varying durations of "intensive" and "continuation" phases of treatment. Bacteriological outcomes were most frequently reported but radiological and clinical data were often included as an implicit or explicit component of the overall definition of outcome.

Terminology used to define long-term outcomes in phase III trials is inconsistent, reflecting evolving differences in protocols and practices. For successful future cumulative meta-analysis, the findings of this review suggest that greater availability of individual patient data and the development of a core outcome set would be desirable. In the meantime, we propose a simple and logical approach which should facilitate combination of key evidence and inform improvements in the.

Results of two randomized controlled phase III studies].

In November the results of 2 clinical phase III trials were published which addressed the effects of alemtuzumab in patients with relapsing-remitting multiple sclerosis MS. These data in the context of the mode of action of alemtuzumab provide evidence for the relevance of immune cells, especially T cells, in the pathophysiology of MS. Experience with long-term effects of alemtuzumab, e. The efficacy and safety of rifaximin in the treatment of hepatic encephalopathy HE are widely known, but they have not been confirmed in Japanese patients with HE.

Treatment periods were 14 days. Blood ammonia B-NH 3 concentration was significantly improved in the rifaximin group, but the difference between the two groups was not significant. The portal systemic encephalopathy index PSE index , including HE grade, was significantly improved in both groups.

In the phase III study, Adverse drug reactions ADRs were seen in The efficacy of rifaximin is sufficient and treatment is well tolerated in Japanese patients with HE and hyperammonemia. Psoriasis is a chronic inflammatory skin disease, affecting patients of a wide age range, including elderly patients. Elderly patients can respond differently to drug treatments and can be more vulnerable to adverse reactions.

There are limited data on biologic therapies for psoriasis in elderly subjects. Secukinumab, a fully human monoclonal antibody that selectively neutralizes ILA, has proven significant efficacy in the treatment of moderate to severe psoriasis. Studies were multicentre, randomized, parallel -group, double-blind, week phase III trials in subjects with moderate to severe plaque psoriasis.

Elderly subjects had higher baseline frequencies of cardiovascular and metabolic disorders. PASI 75 response was reached by The total rate of adverse events was similar between elderly and younger subjects. Phase ii involved the construction of a pilot facility and operation of two pilots. Phase iii of the Advanced Anodes and Cathodes Program was aimed at bench experiments to permit the resolution of certain questions to be followed by three pilot cells. All of the milestones related to materials, in particular metal purity, were attained with distinct improvements over work in previous phases of the program.

Some excellent metal purity results have been obtained with anodes of the following composition: Further improvements in anode material composition appear to be dependent on a better understanding of oxide solubilities in molten cryolite. For that reason, work was commissioned with an outside consultant to model the MeO - cryolite systems. That work has led to a better understanding of which oxides can be used to substitute into the NiO-Fe2O3 ceramic phase to stabilize the ferrites and reduce their solubility in molten cryolite. An extensive number of vertical plate bench electrolysis cells were run to try to find conditions where high current efficiencies could be attained.

TiB2-G plates were very inconsistent and led to poor wetting and drainage. Pure TiB2 did produce good current efficiencies at small overlaps shadowing between the anodes and cathodes. This bench work with vertical plate anodes and cathodes reinforced the importance of good cathode wetting to attain high current efficiencies.

Because of those conclusions, new wetting work was commissioned and became a major component of the research during the third year of Phase III. While significant progress was made in several areas, much work. From research to phase III : preclinical, industrial and clinical development of the Sanofi Pasteur tetravalent dengue vaccine. The vaccine is genetically and phenotypically stable, non-hepatotropic, less neurovirulent than YFV 17D, and does not infect mosquitoes by the oral route.

In vitro and in vivo preclinical studies showed that CYD TDV induces controlled stimulation of human dendritic cells, and significant immune responses in monkeys. The vaccine has now been administered to more than children and adults from dengue endemic and non-endemic areas and no safety concerns have arisen in any of the completed or ongoing trials. A three-dose vaccination regimen induces an immune response against all four serotypes in the large majority of vaccinees.

Preexisting flavivirus immunity favors quicker and higher immune responses to CYD TDV, without adversely effecting clinical safety or increasing vaccine viremia. The observed level and nature of the cellular immune responses in humans are consistent with the good safety and immunogenicity profile of the vaccine. Preliminary results of an ongoing, proof-of-concept efficacy and large scale safety study in Thai children are expected by the end of Here we discuss the different steps and challenges of developing CYD TDV, from research to industrialization, and summarize some of the challenges to the successful.

Three 2-h…. Data were gathered on eight matched outlier pairs of schools during the school year. Background Personalized medicine is a growing area of research which aims to tailor the treatment given to a patient according to one or more personal characteristics. These characteristics can be demographic such as age or gender, or biological such as a genetic or other biomarker. While adaptive designs allow planned modifications based on accumulating information during a trial, non-adaptive designs are typically simpler but less flexible.

Methods and Findings We have undertaken a comprehensive review of biomarker-guided adaptive trial designs proposed in the past decade. We have identified eight distinct biomarker-guided adaptive designs and nine variations from studies. Substantial variability has been observed in terms of how trial designs are described and particularly in the terminology used by different authors. We have graphically displayed the current biomarker-guided adaptive trial designs and summarised the characteristics of each design.

Conclusions Our in-depth overview provides future researchers with clarity in definition, methodology and terminology for biomarker-guided adaptive trial designs. The incorporation of novel agents such as bortezomib and lenalidomide into initial therapy for multiple myeloma has improved the response rate of induction regimens. Together, these and other strategies have contributed to a prolongation of progression-free and overall survival in myeloma patients, and an increasing proportion are able to sustain a remission for many years.

Despite these improvements, however, the vast majority of patients continue to suffer relapses, which suggests a prominent role for either primary, innate drug resistance, or secondary, acquired drug resistance. This review will focus on novel drugs that have reached phase III trials, including carfilzomib and pomalidomide, which have recently garnered regulatory approvals. Among the factors proposed to explain the ProTECT III and SyNAPSe results, the investigators themselves and others have cited: 1 the pathophysiological complexity of TBI itself; 2 issues with the quality and clinical relevance of the preclinical animal models; 3 insufficiently sensitive clinical endpoints; and 4 inappropriate clinical trial designs and strategies.

This paper highlights three critical trial design factors that may have contributed substantially to the negative outcomes: 1 suboptimal doses and treatment durations in the Phase II studies; 2 the strategic decision not to perform Phase IIB studies to optimize these variables before initiating Phase III ; and 3 the lack of incorporation of the preclinical and Chinese Phase II results, as well as allometric scaling principles, into the Phase III designs. Given these circumstances and the exceptional pleiotropic potential of progesterone as a TBI and stroke therapeutic, we are advocating a return to Phase IIB testing.

We advocate the incorporation of dose and schedule optimization focused on lower doses and a longer duration of treatment, combined with the addressing of other potential trial design problems raised by the authors in the recently published trial results. Accelerated re-epithelialization of partial-thickness skin wounds by a topical betulin gel: Results of a randomized phase III clinical trials program. The clinical significance of timely re-epithelialization is obvious in burn care, since delayed wound closure is enhancing the risk of wound site infection and extensive scarring.

Topical treatments that accelerate wound healing are urgently needed to reduce these sequelae. Evidence from preliminary studies suggests that betulin can accelerate the healing of different types of wounds, including second degree burns and split-thickness skin graft wounds. The goal of this combined study program consisting of two randomized phase III clinical trials in parallel is to evaluate whether a topical betulin gel TBG is accelerating re-epithelialization of split-thickness skin graft STSG donor site wounds compared to standard of care.

The primary efficacy assessment was the intra-individual difference in time to wound closure assessed from digital photographs by three blinded experts. A total of patients were included and treated in the two trials. Wounds closed faster with TBG than without it Audits have been proposed for estimating possible recruitment rates to randomized controlled trials RCTs , but few studies have compared audit data with subsequent recruitment rates.

To compare the accuracy of estimates of potential recruitment from a retrospective consecutive cohort audit of actual participating sites and recruitment to four Phase III multisite clinical RCTs. The proportion of potentially eligible study participants estimated from an inpatient chart review of people with life-limiting illnesses referred to six Australian specialist palliative care services was compared with recruitment data extracted from study prescreening information from three sites that participated fully in four Palliative Care Clinical Studies Collaborative RCTs.

The predominant reasons for ineligibility in the audit and RCTs were analyzed. The audit overestimated the proportion of people referred to the palliative care services who could participate in the RCTs pain Ineligibility for general criteria language, cognition, and geographic proximity varied between studies, whereas the reasons for exclusion were similar between the audit and pain and anorexia studies but not for delirium or bowel obstruction.

The retrospective consecutive case note audit in participating sites did not predict realistic recruitment rates, mostly underestimating the impact of study-specific inclusion criteria. These findings have implications for the applicability of the results of RCTs.

Secondary menu

Prospective pilot studies are more likely to predict actual recruitment. A phase III randomized trial of gantenerumab in prodromal Alzheimer's disease. We evaluated treatment effects on cerebrospinal fluid biomarkers all patients and amyloid positron emission tomography substudy. Safety was assessed in patients who received at least one dose. Of the patients screened, were randomized. The study was halted early for futility; dosing was discontinued; and the study was unblinded. Exploratory analyses suggested a dose-dependent drug effect on clinical and biomarker endpoints.

The study was stopped early for futility, but dose-dependent effects observed in exploratory analyses on select clinical and biomarker endpoints suggest that higher dosing with gantenerumab may be necessary to achieve clinical efficacy. Registered on October 14, Estimation of parameters related to vaccine efficacy and dengue transmission from two large phase III studies. A tetravalent dengue vaccine was shown to be efficacious against symptomatic dengue in two phase III efficacy studies performed in five Asian and five Latin American countries.

The objective here was to estimate key parameters of a dengue transmission model using the data collected during these studies. Parameter estimation was based on a Sequential Monte Carlo approach and used a cohort version of the transmission model. Serotype-specific basic reproduction numbers were derived for each country. Parameters related to serotype interactions included duration of cross-protection and level of cross-enhancement characterized by differences in symptomaticity for primary, secondary and post-secondary infections.

We tested several vaccine efficacy profiles and simulated the evolution of vaccine efficacy over time for the scenarios providing the best fit to the data. Two reference scenarios were identified. The first included temporary cross-protection and the second combined cross-protection and cross-enhancement upon wild-type infection and following vaccination. Our study is an important first step in deriving a general framework that combines disease dynamics and mechanisms of vaccine protection that could be used to assess the impact of vaccination at a population level.

Published by Elsevier Ltd.. Virologically confirmed dengue VCD episode was defined with a positive test for dengue nonstructural protein 1 antigen or dengue polymerase chain reaction. Compared with VCD, the sensitivity and specificity of probable dengue definition were Overall positive and negative predictive values were Vaccination-induced bias toward false-positive diagnosis was more pronounced among individuals seronegative at baseline.

There is an urgent need for new practical, dengue-specific diagnostic algorithms now that CYD-TDV is approved in a number of dengue-endemic countries. Assumptions of expected benefits in randomized phase III trials evaluating systemic treatments for cancer. RCTs evaluating systemic therapy in adult cancer patients published in 10 journals from January 1, , through December 31, , were identified. Data were extracted from each publication independently by two investigators.

A total of RCTs met the eligibility criteria and were included in the analysis. Given the limited resources available to conduct clinical trials, it is important to understand how trial sponsorship differs among different therapeutic modalities and cancer types and to consider the ramifications of these differences.

We searched clinicaltrials. The burden of childhood asthma and its risk factors is an important but neglected public health challenge in Latin America. Per-country adjusted logistic regressions were performed, and combined effect sizes were calculated with meta-analyses. In children aged years, current wheeze was negatively associated with higher fruit intake adjusted odds ratio [aOR] 0.

Current rhino-conjunctivitis and eczema were statistically negatively associated with fruit intake aOR 0. A higher intake of fruits and vegetables was associated with a lower prevalence of allergic symptoms in Latin American children. Conversely, intake of fastfood was positively associated with a higher prevalence of wheeze in adolescents. Improved dietary habits in children might help reduce the epidemic of allergic symptoms in Latin America. Food interventions in asthmatic children are needed to evaluate the possible public health impact of a better diet on respiratory health.

Based on the suboptimal research pathways that finally led to multicenter randomized clinical trials MRCTs of treadmill training with partial body weight support and of robotic assistive devices, strategically planned successive stages are proposed for pilot studies of novel rehabilitation interventions Stage 1, consideration-of-concept studies, drawn from animal experiments, theories, and observations, delineate the experimental intervention in a small convenience sample of participants, so the results must be interpreted with caution.

Stage 2, development-of-concept pilots, should optimize the components of the intervention, settle on most appropriate outcome measures, and examine dose-response effects. A well-designed study that reveals no efficacy should be published to counterweight the confirmation bias of positive trials. Stage 3, demonstration-of-concept pilots, can build out from what has been learned to test at least 15 participants in each arm, using random assignment and blinded outcome measures.

A control group should receive an active practice intervention aimed at the same primary outcome. A third arm could receive a substantially larger dose of the experimental therapy or a combinational intervention. If only 1 site performed this trial, a different investigative group should aim to reproduce positive outcomes based on the optimal dose of motor training. Stage 3 studies ought to suggest an effect size of 0. By developing a consensus around acceptable and necessary practices for each stage, similar to CONSORT recommendations for the publication of phase III clinical trials, better quality pilot studies may move quickly into better designed and more successful MRCTs of experimental interventions.

Dose-dense temozolomide for newly diagnosed glioblastoma: a randomized phase III clinical trial. Radiotherapy with concomitant and adjuvant temozolomide is the standard of care for newly diagnosed glioblastoma GBM. Stratification included clinical factors and tumor MGMT methylation status.

Patients were randomly assigned to standard temozolomide arm 1 or DD temozolomide arm 2 for 6 to 12 cycles. The primary end point was OS. Secondary analyses evaluated the impact of MGMT status. A total of patients were randomly assigned to either arm 1 or arm 2 1, registered.

No statistically significant difference was observed between arms for median OS Efficacy did not differ by methylation status. Gilbert, Mark R. Purpose Radiotherapy with concomitant and adjuvant temozolomide is the standard of care for newly diagnosed glioblastoma GBM.

Results A total of patients were randomly assigned to either arm 1 or arm 2 1, registered. Topical analgesics can be defined as topical formulations containing analgesics or co-analgesics. Since , interest in such formulations has been on the rise. There are, however, four critical issues in the research and development phases of topical analgesics: 1 The selection of the active pharmaceutical ingredient. Analgesics and co-analgesics differ greatly in their mechanism of action, and it is required to find the most optimal fit between such mechanisms of action and the pathogenesis of the targeted neuropathic pain.

For relevant clinical efficacy, specific characteristics for the selected vehicle eg, cream base or gel base are required, depending on the physicochemical characteristics of the active pharmaceutical ingredient s to be delivered. In fact, we will demonstrate that underdosing is one of the major hurdles to detect meaningful and statistically relevant clinical effects of topical analgesics. End point selection can make or break a trial.

For instance, to include numbness together with tingling as a composite end point for neuropathic pain seems stretching the therapeutic impact of an analgesic too far. Given the fast onset of action of topical analgesics usually within 30 minutes , enrichment designs might enhance the chances for success, as the placebo response might decrease. Topical analgesics may become promising inroads for the treatment of neuropathic pain, once sufficient attention is given to these four key aspects. Factors associated with reduced early survival in the Oxford phase III medial unicompartment knee replacement.

The aim of this study was to determine the prognostic value of preoperative patellofemoral osteoarthritis, BMI and age for implant survival of unicompartmental knee arthroplasty UKA performed in patients meeting strict admission criteria.

Stakeholder perspectives on the use of positron emission tomography in phase III oncology trials in the UK. Responses were analysed quantitatively and by qualitative content analysis of free-text responses.

A total of responses were received from a wide range of stakeholders representing several professional groups and working environments. There was the general perception that using PET in clinical research is beneficial in oncology. Other factors included limited coverage of PET in training, uncertainty about developing imaging protocols or the status of tracers other than 18F-fluorodeoxyglucose, and low awareness of the role of PET in patient selection for therapeutic trials.

Patient concerns about radiation were not perceived as a research barrier. Interventions that improve the availability and funding pathways for PET research scans and that increase researcher awareness could help promote the use of PET for phase III oncology trials in the UK. The paper focuses on the development of the phase III module, collaborating with seven European countries, including a patient sample of patients.

The phase II FA15 was revised on the basis of qualitative analyses comments of the patients , quantitative results descriptive statistics as well as the multi-item response theory analyses.

This longitudinal study extends the previous research on low participation rates and high dropout rates in phase III cardiac rehabilitation CR exercise programmes. It examines the correlates of motivation and participation 6 months after inpatient phase II CR T1 and the predictors of dropout 6 months later T2 using the health action process approach HAPA. Risk perception, outcome expectancies, self-efficacy, intention at T1 , and participation at T1 and T2 in relation to phase III CR programmes was assessed in patients. Group differences were confirmed in outcome expectancies and self-efficacy.

Dropouts and maintainers differed in intention and self-efficacy at T1. One equation was created for each of five sub-seasons based on the daily lightning climatology instead of by month as was done in Phase II. The assumption was that these equations would capture the physical attributes that contribute to thunderstorm formation more so than monthly equations. However, the SS values in Section 5. Three warm seasons were added to the Phase II dataset to increase the POR from 17 to 20 years , and data for October were included since the daily climatology showed lightning occurrence extending into that month.

None of the three methods tested to determine the start of the subseason in each individual year were able to discern the start dates with consistent accuracy. Therefore, the start dates were determined by the daily climatology shown in Figure 10 and were the same in every year. The procedures used to create the predictors and develop the equations were identical to those in Phase II.

The equations were made up of one to three predictors. TI and the flow regime probabilities were the top predictors followed by 1-day persistence, then VT and Ll. The reason for the degradation may be due to the fact that the same sub-season start dates were used in every year. It is likely there was overlap of sub-season days at the beginning and end of each defined sub-season in each individual year, which could very well affect equation.

  5. The primary end point was overall survival OS. Bone scan response BSR at week 12 as assessed by independent review committee was the secondary end point; radiographic progression-free survival rPFS and effects on circulating tumor cells CTCs , bone biomarkers, serum prostate-specific antigen PSA , and symptomatic skeletal events SSEs were exploratory assessments. Median OS was Open-label, phase III trial evaluating whether sunitinib was superior or equivalent to sorafenib in hepatocellular cancer.

    Patients were stratified and randomly assigned to receive sunitinib Primary end point was overall survival OS. Early trial termination occurred for futility and safety reasons. For sunitinib and sorafenib, respectively, median OS was 7. Median OS was similar among Asian 7. Sunitinib was associated with more frequent and severe adverse events AEs than sorafenib. Discontinuations owing to AEs were similar sunitinib, OS with sunitinib was not superior or equivalent but was significantly inferior to sorafenib.

    OS was comparable in Asian and hepatitis B-infected patients. OS was superior in hepatitis C-infected patients who received sorafenib. Sunitinib-treated patients reported more frequent and severe toxicity. Efforts during Phase III focused mainly on the shell-alloy systems.

    A high melting point alloy, PH stainless steel, was considered. The experimental part of the program was conducted at ORNL and commercial foundries, where wax patterns were injected, molds were invested, and alloys were poured. Shell molds made of fused-silica and alumino-silicates were considered. A literature review was conducted on thermophysical and thermomechanical properties alumino-silicates. Material property data, which were not available from material suppliers, was obtained.

    A comparison between the predicted material property data and measured property data was made. It was found that most material properties were accurately predicted only over several temperature ranges. No experimental data for plastic modulus were found. Thus, several assumptions were made and ProCAST recommendations were followed in order to obtain a complete set of mechanical property data at high temperatures.

    Thermal expansion measurements for the PH alloy were conducted during heating and cooling. As a function of temperature, the thermal expansion for both the alloy and shell mold materials showed different evolution on heating and cooling. Numerical simulations were performed using ProCAST for the investment casting of PH stainless steel parts in fused silica molds using the thermal expansion obtained on heating and another one with thermal expansion obtained on cooling. Since the fused silica shells had the lowest thermal expansion properties in the industry, the dewaxing phase, including the coupling between wax-shell systems, was neglected.

    The shell mold was considered to be a pure elastic material. The alloy dimensions. Novel concepts for the compression of large volumes of carbon dioxide- phase III. In Phase III , a pilot compression plant consisting of a multi-stage centrifugal compressor with cooled diaphragm technology has been designed, constructed, and tested. The power savings, heat exchanger effectiveness, and temperature drops for the cooled diaphragm were all slightly higher than predicted values but showed the same trends.

    Optical studies of blue phase III , twist-bend and bent-core nematic liquid crystals in high magnetic fields. This dissertation is mainly divided into three parts. First, the dynamic light scattering measurements on both calamitic and bent-core nematic liquid crystals, carried out in the new split-helix resistive magnet at the National High Magnetic Field Laboratory, Tallahassee is discussed. In a nematic liquid crystal the molecules tend to be aligned along a constant direction, labeled by a unit vector or "director" n. However, there are fluctuations from this average configuration.

    These fluctuations are very large for long wavelengths and give rise to a strong scattering of light. The magnetic field reduces the fluctuations of liquid crystal director n. The relaxation rate and inverse scattered intensity of director fluctuations exhibit a linear dependence on field-squared up to 25 Tesla. We also observe evidence of field dependence of certain nematic material parameters. In the second part of the dissertation, magneto-optical measurements on two liquid crystals that exhibit a wide temperature-range amorphous blue phase BPIII are discussed. Blue phase III is one of the phases that occur between chiral nematic and isotropic liquid phases.

    Samples were illuminated with light from blue laser; the incident polarization direction of the light was parallel to the magnetic field. This effect appears to increase non-linearly with the field strength. The effect of high fields on established BPIII's is also discussed, in which we find significant hysteresis and very slow dynamics.

    Possible explanations of these results are discussed. In the third part of the dissertation, magneto-optic measurements on two odd-numbered dimer molecules. A comparison of liquid and solid culture for determining relapse and durable cure in phase III TB trials for new regimens. Tuberculosis kills more people than any other infectious disease, and new regimens are essential. The primary endpoint for confirmatory phase III trials for new regimens is a composite outcome that includes bacteriological treatment failure and relapse.

    Culture methodology is critical to the primary trial outcome. Patients in clinical trials can have positive cultures after treatment ends that may not necessarily indicate relapse, which was ascribed previously to laboratory cross-contamination or breakdown of old lesions. The data from this trial, therefore, provide a unique opportunity to investigate and compare the incidence of false 'isolated positives' in liquid and solid media and their potential impact on the primary efficacy results.

    A total of 12, sputum samples were available from patients; cultures were more often positive on MGIT than LJ. In patients with a favourable trial outcome, 9.
