Phase 1 studies are likely to provide the least reliable data on efficacy because
Effects are unlikely at the lowest dose is tested.
189
In a phase 1 oncology study and adults the subjects are likely to be
Patients with cancer who have failed standard therapy.
190
In a phase 3 trial subjects are randomize to treatment group and a control group the assignments remain unchanged for the duration of the trial this is an example of what study design
Parallel design
191
The declaration of Helsinki advises this design for clinical trials whenever possible
Treatment drug with a comparator | control
192
Bias in clinical trial can result from
Aspects of trial design, operational aspects of the trial, statistical analysis and evaluation of the results.
193
The most common techniques utilized to prevent bias in a clinical trial R
Randomization in blinding
194
In a two group parallel design trial neither the investigator nor the subject is aware of whether the group is the treatment drug or a placebo. This is an example of
Double blinding
195
In a double blind placebo controlled design the reasons for the blinding of the investigator include
Prevent the investigator from reviewing the treatment group more strenuously, prevent the investigator from not recording or reporting serious adverse events in the treatment group, prevent the investigator from making protocol changes which favor of the treatment group.
196
The goals of a phase 4 trial include
Detection of rare side effects, detection of side effects associated with chronic use of the drug, and desensitization and loss of the fact of the drug upon continued treatment.
197
And important rare side effect is observed for a drug phase for trial. The likely outcome would be
The sponsor reports it to the FDA which then imposes a black box warning on the product label.
198
Drug trial, which phase would most influence FDA approval and the final product label for a drug is
Phase 3
