Autonomic Blockade for High Blood Pressure

Nashville, Tennessee
The purpose of this study is to better understand the role of the abdominal veins (splanchnic capacitance) and the sympathetic nervous system in human hypertension. The investigators will test the hypothesis that constriction of abdominal veins due to sympathetic activation contributes to human hypertension. Splanchnic capacitance will be assessed in normotensive and hypertensive subjects at baseline and during acute blockade of the autonomic nervous system.

Nitroglycerin for Migraine

Bronx, New York
Migraine is the most common headache disorder, prevalent in 18% of females and 6% of males. Emergency room visits, physician consults, hospitalizations, medications, and indirect costs such as lost work days and decreased productivity place the global economic burden of migraines at over 20 billion dollars. It is prevalent in 28 million people in the US alone. Symptoms include unilateral, throbbing, debilitating headache pain accompanied by nausea, vomiting, photophobia, and phonophobia. Upwards of 75% of migraine patients have reduced functionability, have lost time at work, and 1/3 of patients require bed rest to manage the symptoms. The health-related impact on quality of life was comparable with that experienced by patients with congestive heart failure, hypertension, or diabetes. While the burden of migraines on our society is clear, the pathophysiology of migraines remains largely unknown. The trigeminovascular system, including the external and internal carotid arteries and their associated sensory fibers which subserve the head have long been implicated in the pain and cutaneous allodynia experienced by migraine patients. Wolff in 1953, was the first to posit that migraine headache pain is the caused by dilation or circumferential expansion of the extracranial carotid artery. He demonstrated that migraineurs had twice the pulse amplitude in their external carotid arteries compared to control subjects and these changes were directly correlated to migraine symptoms. In a 2008 study, randomized migraineurs received nitroglycerin via peripheral IV or placebo for 20 minutes prior to obtaining magnetic resonance angiography (MRA). Nitroglycerin, a potent dilator of blood vessels, reliably induced migraine-like pain in up to 80% of patients, and transient dilation of vessels of up to nearly 40%, mostly in the extracranial vessels. Sumatriptan's efficacy in migraine relief provides further evidence for this theory, as it is a selective extracranial vessel constrictor which does not cross the blood brain barrier. The goal of this current work is to utilize the direct, real-time angiography, which provides a high resolution map of vasculature, and demonstrate changes in vessel flow in patients who have migraine headache attacks. This information may guide therapeutic interventions in the future in order to better treat these migraine patients.

Why Other Patients Applied

"I have dealt with voice and vocal fold issues related to paralysis for over 12 years. This problem has negatively impacted virtually every facet of my life. I am an otherwise healthy 48 year old married father of 3 living. My youngest daughter is 12 and has never heard my real voice. I am now having breathing issues related to the paralysis as well as trouble swallowing some liquids. In my research I have seen some recent trials focused on helping people like me."

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

"I've tried several different SSRIs over the past 23 years with no luck. Some of these new treatments seem interesting... haven't tried anything like them before. I really hope that one could work."

"As a healthy volunteer, I like to participate in as many trials as I'm able to. It's a good way to help research and earn money."

"I changed my diet in 2020 and I’ve lost 95 pounds from my highest weight (283). I am 5’3”, female, and now 188. I still have a 33 BMI. I've been doing research on alternative approaches to continue my progress, which brought me here to consider clinical trials."

Why We Started Power

We started Power when my dad was diagnosed with multiple myeloma, and I struggled to help him access the latest immunotherapy. Hopefully Power makes it simpler for you to explore promising new treatments, during what is probably a difficult time.

Frequently Asked Questions

How much do clinical trials pay?
Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.
How do clinical trials work?
After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length is 12 months.
How do I participate in a study as a "healthy volunteer"?
Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.
What does the "phase" of a clinical trial mean?
The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.
Do I need to be insured to participate in a medical study ?
Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.
What are the newest clinical trials ?
Most recently, we added Nitroglycerin for Migraine and Autonomic Blockade for High Blood Pressure to the Power online platform.
