Clinical Trials are Longitudinal........... Why Wait to Take a Look?? By their very nature, almost all clinical trials are longitudinal. It is practically impossible to recruit, enrol and randomize all the required subjects at exactly the same time. Therefore, subjects and their subsequent data are accumulated sequentially over time. Sometimes, instead of using fixed period trial methodology, researchers find it necessary (or even desirable) to employ a group sequential design with a number of planned interim analyses in a clinical trial. Efficacy & Economics Together……..A Powerful Force!! Sequential statistical methods have been developing over recent decades for ethical, administrative and economic reasons. In human and animal trials, it is essential to monitor results to ensure that the subjects are not exposed to unsafe, inferior or ineffective treatments. Equally, if a trial is showing a very positive result of overwhelming efficacy, early stopping means that a new product can be brought to market sooner. Thus saving time, money and other equally scarce resources. nTerim Software……..Power & Sample Size for Group Sequential Trials But group sequential designs present particular challenges when attempting to calculate sample size and power. nTerim has been developed to provide power and sample size calculations for group sequential trials. The sample size and power calculations in nTerim use the alpha spending function method of Lan & DeMets, and include the spending functions from O’Brien & Fleming, Pocock, Hwang-Shih-DeCani, and others.

Comprehensive Meta-Analysis

Fri, 18 May 2012 12:00:15 -0400

What is a Meta-Analysis?

Meta-analysis is the statistical procedure for combining data from multiple studies. When the treatment effect (or effect size) is consistent from one study to the next, meta-analysis can be used to identify this common effect. When the effect varies from one study to the next, meta-analysis may be used to identify the reason for the variation. Why do a Meta-Analysis? Decisions about the utility of an intervention or the validity of a hypothesis cannot be based on the results of a single study, because results typically vary from one study to the next. Rather, a mechanism is needed to synthesize data across studies. Narrative reviews had been used for this purpose, but the narrative review is largely subjective (different experts can come to different conclusions) and becomes impossibly difficult when there are more than a few studies involved. Meta-analysis, by contrast, applies objective formulas (much as one would apply statistics to data within a single study), and can be used with any number of studies. Meta-Analysis in applied and basic research Pharmaceutical companies use meta-analysis to gain approval for new drugs, with regulatory agencies sometimes requiring a meta-analysis as part of the approval process. Clinicians and applied researchers in medicine, education, psychology, criminal justice, and a host of other fields use meta-analysis to determine which interventions work, and which ones work best. Meta analysis is also widely used in basic research to evaluate the evidence in areas as diverse as sociology, social psychology, sex differences, finance and economics, political science, marketing, ecology and genetics, among others. Where does Meta-Analysis fit in the research process? Publications Many journals encourage researchers to submit systematic reviews and meta-analyses that summarize the body of evidence on a specific question, and this approach is replacing the traditional narrative review. Meta-analyses also play supporting roles in other papers. For example, a paper that reports results for a new primary study might include a meta-analysis in the introduction to synthesize prior data and help to place the new study in context. Planning new studies Meta-analyses can play a key role in planning new studies. The meta-analysis can help identify which questions have already been answered and which remain to be answered, which outcome measures or populations are most likely to yield significant results, and which variants of the planned intervention are likely to be most powerful. Grant applications Meta-analyses are used in grant applications to justify the need for a new study. The meta-analysis serves to put the available data in context and to show the potential utility of the planned study. The graphical elements of the meta-analysis, such as the forest plot, provide a mechanism for presenting the data clearly, and for capturing the attention of the reviewers. Some funding agencies now require a meta-analysis of existing research as part of the grant application to fund new research.

EquivTest is Equivalence Testing Software providing extensive tests and confidence intervals for equivalence testing as well as a comprehensive set of pharmacokinetic calculations. EquivTest provides a range of tests and confidence intervals for the statistical analysis of equivalence test studies. Researchers working in clinical equivalence and bioavailability studies can now use this equivalence testing software to investigate equivalence according to FDA and CPMP guidelines. EquivTest now has the added feature of simple-to-use, built-in pharmacokinetic measurement functions. It provides a fast and easy means of calculating and plotting the most commonly used pharmacokinetic parameters such as;

Cmax, Tmax, Lag Time, AUC(0-t), AUC(t-∞),
AUC(0-∞), AUC(0-t)/AUC(0-∞), Mean Residence Time,
AUMC(0-t), AUMC(0-∞), Half-Life, Elimination Rate Constant (λ).

All of the pharmacokinetic calculations in EquivTest are based on noncompartmental methods of analysis for the estimation of pharmacokinetic parameters. Once the pharmacokinetic parameters have been calculated, there is no need to export data to another application, because EquivTest can proceed to perform the bioequivalence phase of the study.
