Paid Clinical Trials in Wisconsin

Wisconsin history is deep and layered. Between Milwaukee and Madison, there are cultural influences in the state that percolate through the rest of the country. Included are medical breakthroughs. You can become involved, and even get paid. There are lots of paid clinical trials for healthy volunteers nearby in Wisconsin.

To find them, you want to look at three main things. One, how many CROs (Clinical Research Organizations) are there, two, how many people are in the state, and three, how many people need to be involved in medical trials continuously to advance the science.

Wisconsin has 5,935,064 people, approximately 220 CROs, and medical experts say 1 out of every 200 people in the USA (.005%) need to be involved in clinical trials on an ongoing basis to meaningfully advance the science year over year.

That means for each of those 220 CROs, there are approximately 134 to 135 individual opportunities. Following we’ll explore a little information that can help you narrow down your choices as to which clinical studies best fit your particular situation.

Demographic Data Helps Show Trial Availability in Wisconsin

A notable bit of data pertaining to paid clinical trials nearby for healthy volunteers will involve local demographics. When you know what sort of “sample pool” medical scientists can draw from, you’ll get a better idea of the sort of studies available, and which might best match your particular situation.

According to census data, 84.3% of Wisconsin are white, 6.34% are black, and 3.35% are 2 or more races. The median age of the state is 38.5, with 50.24% being female, and 49.76% being male.

We have compiled the following list of paid clinical trials for healthy volunteers, click the Search All button at the bottom to find more:

Integrated Cancer Repository for Cancer Research
Recruiting
The iCaRe2 is a multi-institutional resource created and maintained by the Fred \& Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer... Read More

The ENHANCE Study: taVNS and Psilocybin
Recruiting
This study will examine whether combining a single dose of psilocybin with non-invasive transcutaneous auricular vagus nerve stimulation (taVNS), a potential inducer of neuroplasticity and enhanced memory formation, will enhance the long-term beneficial behavioral effects of psilocybin when compared to sham taVNS or no VNS by allowing memory for insights gained during the psychedelic experience to remain vivid after they will have faded in subjects who receive psilocybin followed by sham taVNS o...

Evaluation of Vitamin A Absorption From Fortified Bouillon
Recruiting
The goal of this clinical trial is to measure how well different formulations of vitamin A (VA) are absorbed by the body when they are added to bouillon (broth) as vitamin A palmitate (VAP). Fortifying bouillon cubes with VA is one potential approach to addressing VA deficiency, which is a major public health issue in many low- and lower-income countries. The main question this study aims to answer is to compare the amount of VA that is absorbed by the body from three different VAP formulations... Read More

Rapid Eye Movement Restoration and Enhancement for Sleep-deprived Trauma-adaptation
Recruiting
The goal of this clinical trial is to find out whether stimulating the brain with electrical current during naps can increase certain kinds of brain activity that happen during sleep and lead to improvements in emotional health and stress resilience. Participants will attend up to 3 study visits, each of which may last up to 4-5 hours. During these visits, participants will wear a high density electroencephalography (hdEEG) cap and take a nap.

Neuromodulation-assisted Ego-disengagement: The NEURO-EGO Study Stage 1
Recruiting
The goal of this clinical trial is to learn whether brain stimulation technology can help people reach a meditative state quickly and easily without years of meditation training. The researchers want to see if this will help people distance themselves from their thoughts and feeling, and if this will lead to improvements in openness and wellbeing the same way meditation can. Participants will: * Complete questionnaires * Perform a guided meditation task (The Bell Task) * Wear a high density el... Read More

Interpreting Wisconsin Diversity Data to Find Paid Trials

What this indicates is that the preponderance of paid clinical trials for healthy volunteers will be aimed at white women in their late thirties, followed by men in a similar category, blacks, and those with 2 or more ethnicities in their background.

Keep in mind, that studies often exist that require no gender or ethnic component to produce valid results. Ultimately, the majority of human beings are so similar in a genetic sense, that unless you’re an expert, it’s hard to tell one person from another under a microscope. That said, there are differences, and that may mean trials calibrated toward one particular group or another.
