First, rats are required to press the lever in response to distinct Go or No-Go tones to initiate a trial (initiation).
Trial initiation and publication/stopping rules (e.g. industry or investigator initiated, publication constraints, sponsor rights to stop the trial) We use a web-based password-protected database (Squiekero, http://www.squiekero.org) for data extraction.
Approval was obtained from the independent ethics committees and institutional review boards at each site before trial initiation.
Heifers were weighed (shrunk) at trial initiation, end of feeding, breeding, and at pregnancy diagnosis.
MATCH uses genomic analysis with in vitro testing of patient tumors to select optimal drug regimens before clinical trial initiation.
In addition, we intend to provide a compound identification number for each of the trials on clinicaltrials.gov at the time of trial initiation.
Professional experience in clinical care, and particularly care of children, predicted favorable attitudes toward nonanimal preclinical models and trial initiation when sub-optimal treatments were available.
Ninety-six multiparous Holstein cows, 105 ± 31 d in milk at trial initiation, were stratified by DIM and randomly assigned to 12 pens of 8 cows each.
Holstein cows (n = 120; 81 ± 8 d in milk at trial initiation), stratified by parity, days in milk, and milk yield, were randomly assigned to 15 pens of 8 cows each.
Twenty-four multiparous Holstein cows averaging 71 d in milk at trial initiation were in a replicated 4 × 4 Latin square design with 28-d periods; one square was comprised of ruminally cannulated cows for rumen measurements.
Key concepts addressed in this record include: compound identification; lead optimization; pharmaceutical profiling; the use of animal models to predict efficacy and safety and toxicological assessment as these relate to the regulatory requirements for Phase I trial initiation.
