We performed a multi-centre phase I study to assess the safety, pharmacokinetics (PK) and pharmacodynamics (PD) of the orally available small molecule mitogen-activated protein kinase kinase (MEK) 1/2 inhibitor, WX-554, and to determine the optimal biological dose for subsequent trials.
Phase I clinical trials are conducted to find recommended doses, where toxicity of the agent is typically assessed to determine what dose is appropriate for subsequent trials.
Compliance with the above procedures was checked via written logs of nutritional intake, and participants were asked to replicate nutritional practices for subsequent trials (adherence = 100%).
Among the concentrations of AS investigated (0, 50, 100, 200, and 400 μM), 200 μM was selected for subsequent trials because this concentration yielded the most transformants.
Additionally, participants were asked to replicate their diet during the first experimental visit for subsequent trials to ensure a similar metabolic state.
The data will go to the Food and Drug Administration and pharmaceutical companies; they, in turn, will use their own platforms for subsequent trials.
This study provides important information on optimal MRI timing for subsequent trials.
This study provides essential information on optimal MRI timing for subsequent trials.
Our present results suggest that Ca2+ could play this role, priming neuronal units for subsequent trials and preparing for LTM formation.
Indeed, for subsequent trials with APC the inclusion criteria have all focused on ensuring high severity of illness, including the important ongoing PROWESS-SHOCK trial [ 8, 9].
Thus, effect sizes with 95% confidence intervals will be calculated in favour of significance testing in order to provide information for subsequent trials.
