The current evidence base for sociobehavioral issues germane to PrEP predominantly comprises data collected in the context of investigational RCTs.
The demographic and behavioral characteristics of trial participants, the acceptability of investigational products, and the community context, may all have a bearing on adherence decisions and capabilities.
Many factors differ between one's engagement with an open-label PrEP regimen and a regimen that is provided in the context of an investigational controlled research trial.
For example participants framed the news within the context of understanding the investigational nature of the gels and the double-blind trial design.
For the time being the detection of CK-19 CTCs as a marker for therapeutic decision making in patients with early breast cancer should be considered investigational and used only in the context of clinical trials.
However, at the present time, rechallenge with an anti-EGFR therapy remains investigational and should be conducted in the context of a clinical trial.
The importance of close and early dialogue with the US Food and Drug Administration FDAA) within the context of mechanisms, such as pre-Investigational New Drug meetings, is also discussed.
As such, the approach described by Pink et al. 18 cannot be implemented in the context of early drug development of a novel investigational agent.
Where the toxicity of an investigational treatment is well known, or thought to be modest in the context of the phase II decision-making process, the primary phase II trial outcome measure will usually be antitumour activity, with toxicity among the secondary outcome measures.
However, in daily clinical practice, conventional biomarkers are always interpreted in the context of their reference values; hence, such a comparison with a new investigational biomarker is sensible.
In this context, we set out to determine whether a multiplex screening strategy built around an investigational quad multiplexed rapid POC test was feasible, preferred to the conventional strategy, and, most importantly, if it improved case finding/detection of HIV and co-infections with linked confirmatory testing and follow-up (notification), even in the absence of clinical suspicion.
