This research is studying Definity ultrasound contrast agent, which is already approved by the Food and Drug Administration (FDA) for the ultrasound evaluation of the liver and heart. This research will investigate the ability to use ultrasound imaging with ultrasound contrast agents to evaluate kidney obstruction. Eligible participants that are enrolled will have two visits (one before and one after the planned surgery to relieve the kidney obstruction).

This phase III trial compares the use of contrast-enhanced multiparametric ultrasound (mp-US) to multiparametric magnetic resonance imaging (mp-MRI) for the diagnosis of clinically significant prostate cancer (PCa). A mp-US is a procedure in which a probe that sends out high-energy sound waves is inserted into the rectum. The sound waves are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissue called a sonogram. Perflutren lipid michrosphere (Definity) is a contrast agent that uses microbubbles to enhance ultrasound images of the prostate. Doctors hope to learn if the Definity-enhanced mp-US imaging technique can accurately direct targeted biopsy for the detection of clinically significant prostate cancer when compared to standard of care mp-MRI.

The Subharmonic Aided Pressure Estimation (SHAPE) technique is a noninvasive ultrasound-based imaging technique that can estimate ambient pressure using subharmonic emissions from ultrasound contrast agents. Ultrasound contrast agents are encapsulated microbubbles (mean diameter \< 8 µm) with a lipid, protein, or polymer shell that traverse the entire vasculature. When the contrast microbubbles are insonated with relatively high acoustic pressures (\>100-150 kPa), these microbubbles act as nonlinear oscillators yielding energy components in the received echo signals at frequencies ranging from the subharmonic (half of transmit frequency) to higher harmonics and even ultraharmonics. Based on empirical evidence, the subharmonic signal exhibits a sigmoidal relationship with incident acoustic pressure i.e., subharmonic signal can be divided into occurrence, growth and saturation stages. In the growth stage, the subharmonic signal has shown sensitivity to ambient pressure characterized by an inverse linear relationship between subharmonic signal and ambient pressure changes. This inverse linear relationship forms the basis for the SHAPE technique. Several pre-clinical and clinical studies have been conducted to utilize the SHAPE technique for in vivo pressure estimation e.g., to diagnose portal hypertension, to estimate intra-cardiac pressures and to determine interstitial fluid pressures. The core imaging mode underpinning the SHAPE technology (subharmonic imaging) is now available on some commercial scanners. In the proposed pilot study, the SHAPE technique will be leveraged for monitoring intracranial pressure (ICP). The use of SHAPE technique for the ophthalmic artery could potentially provide an accurate noninvasive method of measuring ICP in patients with idiopathic intracranial hypertension (IIH) and other conditions of raised ICP, which would revolutionize the field.

Why Other Patients Applied

"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."

"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 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."

"I've been struggling with ADHD and anxiety since I was 9 years old. I'm currently 30. I really don't like how numb the medications make me feel. And especially now, that I've lost my grandma and my aunt 8 days apart, my anxiety has been even worse. So I'm trying to find something new."

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.
