By enrolling as many and as diverse a population as possible, the data will be more likely to reflect real-world efficacy, he adds. Expectations for these agents, however, need to be tempered. A patient trial of the lopinavir plus ritonavir combination has already failed, Cao and colleagues reported in the New England Journal of Medicine in March, although subgroup analyses of the data suggest the drugs might still have efficacy.
Researchers have been finding preliminary antiviral efficacy signals with repurposed agents including hydroxychloroquine for decades, says Bausch. But these rarely translate into clinical success. But I am opposed to what I'm seeing around the world, with this drug being worked into clinical algorithms already. This leaves plenty of room—and need—for other agents. Beyond the traditional antivirals, a few candidates are already attracting attention.
Virally targeted antibodies might be able to help the immune system to ward of infection, for example. There is also hope that anti-inflammatory agents might be able to keep overactive immune responses in check. The Solidarity trial has been set up such that some of these other agents can be added in as new arms, as the trial progresses.
But there is a trade-off here—and elsewhere throughout the COVID drug development landscape—between speed and breadth. The different classes of agents might also be most useful in different stages of diseases. Antiviral agents, for example, might be most beneficial when used as early as possible in the course of disease, prophylactically even if possible.
Anti-inflammatory agents might, by contrast, be harmful if used early on, if they dampen the immune response too much. Many more trials, consequently, are going to be needed. WHO might yet start another Solidarity trial in an earlier disease setting. Industry sponsored trials will also be needed, both to prioritise which agents to test at scale and potentially to secure regulatory approvals.
Gilead is aiming to recruit more than patients into its phase 3 trial of remdesivir, in addition to its collaborative efforts with WHO, the US National Institutes of Health, and others. Having multiple parties and funders pursue their own favoured agents also provides a safeguard against groupthink, adds Kieny. Bausch similarly urges for more coordination around clinical data collection.
While finding effective drugs is no easy feat on its own, it is also only at best a single step on a long journey towards taming the COVID beast. Manufacturing, regulatory approval, and supply and access decisions are also going to need collective solutions, as will vaccine and diagnostic development.

Only a third-party knows whether the medication was real or not. The placebo effect is a crucial component of double-blind studies. A placebo is an inactive substance that has no effect on the individual who is taking it. Subjects in double-blind studies are typically divided into three different groups: treatment or experimental group, placebo group, and control group. Participants who are not receiving any treatment are placed in the control group.
This group serves as a baseline for determining whether the medication in question has any significant effects. If the control group gets better over time, then this improvement will set a standard against which the other two groups are compared.
People placed in the treatment group are given the actual medication, while subjects in the placebo group are offered a placebo pill. Neither the participants in the treatment and placebo groups nor the experimenters have the information on who is receiving the real drug. At the end of the trial, data collected from the groups are compared to determine if the treatment had the expected outcome. But if people in the treatment group improve more than those in the placebo one, then the results can be attributed to the effect of the medication.
Several different types of blind studies are being used in research, such as double-blind comparative studies, single-blind studies, and triple-blind studies. In double-blind comparative studies, one group of participants is given a standard drug instead of a placebo. These studies compare the effects of new medicine and an old one whose impact has already been proven.
This kind of study is useful in determining whether a new treatment is more effective than the existing one. In single-blind studies, only the participants are not informed whether they are receiving the real treatment. The experimenters, on the other hand, know which participants belong to which group. Triple-blind studies are clinical trials in which knowledge about the treatment is hidden not only from subjects and experimenters but also from anyone involved in organizing the study and data analysis.
Despite their significance, double-blind studies hold a number of limitations and are not applicable to every type of research. To be effective, a double-blind study must include at least participants and preferably as many as Although effective treatments can also be proven in some small-scale trials, many double-blind studies are too limited in size to provide a representative sample and establish meaningful patterns.
Double blinding is not feasible in all types of trials. For instance, it is not possible to design studies on therapies such as acupuncture, physical therapy, diet, or surgery in a double-blind manner. Participants in clinical trials must be informed of the possible side effects that may result from the experimental treatment. However, the mere suggestion of a negative outcome may lead to the adverse placebo effect, also known as the nocebo effect.
It can result in participant dropouts and the need for additional medications to treat the side effects. In research, the use of a placebo is acceptable only in situations when there is no proven acceptable treatment for the condition in question. For ethical reasons, participants must always be informed of the possibility that they will be given a placebo. As a consequence, some participants may think that they feel the effects of the placebo, which makes them believe that they are in the treatment group.
This high positive expectancy is a disadvantage that can lead to a misinterpretation of the results. Double-blind procedures are very expensive. They may take several months to complete, as experiments often require numerous trials using different groups in order to collect enough data.
As a result, double-blind studies can cost up to several million dollars, depending on the amount of work required and the industry in which the product is being tested.

All participants in the study will take a pill, but only some of them will receive the real drug under investigation.
The rest of the subjects will receive an inactive placebo. With a double-blind study, the participants and the experimenters have no idea who is receiving the real drug and who is receiving the sugar pill. Double-blind experiments are simply not possible in some scenarios. For example, in an experiment looking at which type of psychotherapy is the most effective, it would be impossible to keep participants in the dark about whether or not they actually received therapy.
So why would researchers opt for such a procedure? There are a couple of important reasons. The double-blind procedure helps minimize the possible effects of experimenter bias. Researchers sometimes have subjective feelings and biases that might have an influence on how the subjects respond or how the data is collected. In one research article, randomized double-blind placebo studies were identified as the "gold standard" when it comes to intervention-based studies.
Imagine that researchers want to determine if consuming energy bars before a demanding athletic event leads to an improvement in performance. The researchers might begin by forming a pool of participants that are fairly equivalent regarding athletic ability. Some participants are randomly assigned to a control group while others are randomly assigned to the experimental group.
Participants are then be asked to eat an energy bar. All of the bars are packaged the same, but some are sports bars while others are simply bar-shaped brownies. The real energy bars contain high levels of protein and vitamins, while the placebo bars do not. Because this is a double-blind study, neither the participants nor the experimenters know who is consuming the real energy bars and who is consuming the placebo bars.
The participants then complete a predetermined athletic task, and researchers collect data performance. Once all the data has been obtained, researchers can then compare the results of each group and determine if the independent variable had any impact on the dependent variable. A double-blind study can be a useful research tool in psychology and other scientific areas. By keeping both the experimenters and the participants blind, bias is less likely to influence the results of the experiment.
A double-blind experiment can be set up when the lead experimenter sets up the study but then has a colleague such as a graduate student collect the data from participants. The type of study that researchers decide to use, however, may depend upon a variety of factors, including characteristics of the situation, the participants, and the nature of the hypothesis under examination.
