Planning study definition

With the transfer of most biopharmaceutical INDs from CBER to CDER in 2003, there has been an increased tendency to apply the small-molecule paradigm for evaluation of QT liability to biopharmaceutical product candidates, and to request information on hERG assays or plans for definitive clinical QT studies. This does not seem reasonable based on the postmarketing safety data for biopharmaceuticals, nor on scientific grounds as discussed above. If these investigations become routinely required, they will only add significant time and costs to the process of biopharmaceutical product evaluation and have little ultimate impact on patient safety. [Pg.320]

An experiment is a planned study of the effect of one or more independent variables (often called factors) on a dependent variable (generally called the response). The important difference between a simple observational study and a designed experiment is that in a designed experiment the factors are varied in a controlled manner. We begin by considering some basic definitions as suggested by Hunter et al. ... [Pg.2304]

Analysis and Interpretation of the Information and data resulting from the exploratory study will provide the basis for designing the final definitive monitoring study Including all elements of the QA/QC plan. For example, decisions must be made on whether or not the selected control area Is adequate and appropriate whether the hypothesized model Is valid whether the study area should be stratified and If so, how what number of samples should be collected at what locations and whether or not the QA/QC plan for sampling is adequate and if not, how it should be changed. [Pg.104]

The unprecedented inclusion of culture-bound syndromes in the DSM-IV (APA, 1994) highlights the need to study such syndromes and the chance to develop a research plan that allows a careful, thorough study of the issue. The DSM-IV contains symptomatic descriptions of 25 culture-bound syndromes developed by the Culture and Diagnosis Group (Mezzich et al., 1996), as well as including the definition of culture-bound syndrome. [Pg.13]

Drug development is ideally a logical, step-wise procedure in which information from small early studies is used to support and plan later larger, more definitive studies. To develop new drugs efficiently, it is essential to identify characteristics of the investigational drugs in the early stages of development and to plan an appropriate development based on this profile. [Pg.779]

The third axis in Fig. 1 is that of the perspective of an economic analysis of medical care. Costs and benefits can be calculated with respect to society s, the patient s, the payer s, and the provider s points of view. A study s perspective determines how costs and benefits are measured, and the economist s strict definition of costs (the consumption of a resource that could otherwise be used for another purpose) may no longer be appropriate when perspectives different from that of society as a whole are used. For example, a hospital s cost of providing a service may be less than its charge. From the hospital s perspective, then, the charge could be an overstatement of the resources consumed for some services. However, if the patient has to pay the full charge, it is an accurate reflection of the cost of the service to the patient. Alternatively, if the hospital decreases its costs by discharging patients early, the hospital s costs may decrease, but patients costs may increase because of the need for increased outpatient expenses that are not covered by their health insurance plan. [Pg.41]

Of particular interest in the present study is the apparent existence of an activated sorption mechanism for nitrogen in partially hydrated zeolite NaA, a further study of which is planned. The less definitely established irreversibly sorbed nitrogen on dehydrated zeolites NaA and NaX, but not on CaA and NaY, is in need of confirmation, and of further characterization. A practical utility of the results is the quantifying of nitrogen uptake from air, which persists even with appreciable sorbed water. This amount can be approximated from the isotherms as the capacity at 0.8 atm. inasmuch as the contribution due to oxygen is very small. Conversely, the isotherms can be used to assess the state of hydration of a zeolite, with the aid of a measurement of the amount of sorbed nitrogen, either by mass loss on evacuation at room temperature in a balance, or by collection of gas evolved on immersion of a sample in water. [Pg.120]

Chances are, you don t have an unlimited amount of time to prepare for the GRE General Test. You have a life outside your plans for graduate school that may include work and family obligations. Or you may already be in school. How can you maximize the study time you do have To study means to give one s attention to learning a subject to look at with careful attention. Notice that the word attention comes up twice in this definition. How you study is as important as how much time you spend studying. [Pg.13]

From a statistical point of view, compelling evidence of unexpected adverse events is the hardest to address satisfactorily. When unanticipated safety concerns arise, the fact that they are unanticipated means by definition that they would not have been addressed in the study protocol or statistical analysis plan and that no prespecified analytical strategy is in place. Additionally, file vast range of possible adverse events that might be anticipated means that controlling adequately for multiplicity problems is difficult (Ellenberg et al., 2003). [Pg.186]
