To achieve this objective, trials of adjuvant therapy must be conducted in high-risk patients.
These results were used to design an objective, prospectively randomised trial in the Cancer and Leukemia Group B and the North American Breast Intergroup: Study CALGB 9741 involved over 2000 volunteer female patients with node-positive operable primary breast cancer.
For readers, an objective reading of trial results, particularly negative results, requires knowledge of a priori and a posteriori estimated ICCs.
If fewer than seven patients achieved an objective response, the trial would close as the study treatment was not more effective than standard chemotherapy.
A major goal of trial registration is to enhance transparency and accountability in the conduct and reporting of clinical trials, an objective achieved by making details about the trial, including source of funding, methods, and design, publicly available [2], [3].
Detailed objectives, trial methods and primary endpoint analyses are presented elsewhere [ 27- 30].
The interviewees were provided with a description of the project and structured interviews were conducted initially focusing on the four project objectives (trial feasibility, facilitating recruitment, facilitating clinical trial delivery, and reporting of adverse drug events).
In an oncology clinical trial, an objective endpoint is survival and a subjective endpoint is a symptom score.
90 Only 1 patient (4%) with platinum-resistant EOC experienced an objective partial response; this trial was subsequently terminated due to poor response rate.
Using a two stage, phase II optimal design, powered to choose between an acceptable response rate of 40% and an unacceptable one of 20%, at the 5% significance level and 90% power, 19 patients were needed in the first stage and if four or less had an objective response than the trial had to be closed because of poor response.
Suppression of skin prick responses to allergen by QGE031 was an exploratory objective (subcutaneous trial).
