TORONTO, ON --(Marketwired - March 24, 2016) - The live webinar on April 12, 2016, will review a recent article in Pain by Cooper et al that summarizes the findings of a meeting convened by IMMPACT, the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials.
The article looked at key considerations and best practices governing design of acute pain studies. A single-dose analgesic study is usually the first step in a clinical development plan to establish the safety and efficacy for an acute pain medication. This first study should be conducted in an established postsurgical model to determine proof of concept, the effective dose range, analgesic properties such as time to onset of analgesic activity, magnitude of analgesic activity, and duration of analgesic effect. The relationship between dose and efficacy/safety also can be defined. Inclusion of a placebo arm allows for determination of the treatment effect and relative safety versus an untreated population. A positive control arm provides validation of the model, and relative potency against an established analgesic medication also can be determined.
Importance of Preclinical Research
Data derived from preclinical in vitro studies and in vivo animal models can provide important guidance on designing the clinical development plan. Determination of receptor binding characteristics, mechanism of action, whether the drug has central or peripheral nervous system activity, the metabolic profile, and the degree of protein binding can provide clues regarding the appropriate clinical models and study designs.
Key elements to consider in every acute pain analgesic study are:
Efficacy and safety in acute pain models. Fully characterizing these factors is essential to any analgesic trial. Efficacy attributes include onset of effect, maximum analgesic effect and duration of effect, and overall effect across the dosing interval. It's also important to characterize the full adverse effect profile.
General research design considerations. A placebo treatment arm and a positive control arm are highly recommended.
Proof of concept and dose ranging. The initial proof-of-concept study should define the dose-response relationship, and comparator analgesics should be used as benchmarks for judging assay sensitivity and the relative efficacy of the investigational compound.
Choosing the right active comparator. In the absence of established standards, it's wise to choose comparators whose mechanism of action is similar to the treatment under study.
The major efficacy domains in acute pain trials are pain intensity and pain relief. Additionally, analgesic onset and duration are important measures in most conditions. The webinar also will address documentation and reporting of adverse events and conclude with 10 best practices and principles that should be factored into every acute pain analgesia trial as recommended by the IMMPACT group.
