A world-first trial led by the University of Sydney found that opioids are not more effective than a placebo for treating acute back and neck pain and may even pose a risk for harm. The researchers argue that treatment guidelines should be updated to advise against using opioids fo...
On microdosing, scientists say the illegal status of the drug has prevented serious research on the topic specifically and what the long-term negative effects may be, while separate placebo studies for microdosing both psilocybin and LSD have found thatusers' expectations are behind at least ...
A run-in period is commonly used in trials of placebo-controlled pharmaceutical studies (49). Of note, a run-in period for a human nutrition RCT may improve participants' health status, because the diet is healthier than the participant's habitual diet, even when that diet is designed to...
Atopic dermatitis (AD) is a common chronic inflammatory skin condition that significantly impairs patients’ quality of life as a result of intense it
Before it was licensed, the rotavirus vaccine had been given to about 11,000 children in placebo-controlled prospective studies. Because intussusception was very rare, studies performed prior to licensure were not big enough to determine that rotavirus vaccine caused the condition. Following the withdr...
drug might not have worked in many other placebo-controlled trials. Financial success would be difficult if a well-conducted trial showed that a new expensive drug is not any better than an old cheap one, or is worse. Head-to-head comparisons of drugs can be subject to bias, in all ...
It is also worth noting that the 90% failure rate is for the drug candidates that are already advanced to phase I clinical trial, which does not include the drug candidates in the preclinical stages. If drug candidates in the preclinical stage are also counted, the failure rate of drug ...
In addition, a country's economy can benefit from R&D, for it can support, boost, and sustain its progress. For example, the United Kingdom's Department of Business Innovation and Skills, or BIS (now known as the Department for Business, Energy and Industrial Strategy), used topublish an...
In this regard, treatment options with predictable and favourable pharmacokinetics, such as lipid formulations of amphotericin B with echinocandin provide a reasonable rationale for phase III randomized, double-blinded, placebo-controlled trials [63]. However, more work on the safety, tolerability, ...
