N-acetylcysteine for Lupus

Columbus, Ohio
Systemic lupus erythematosus (SLE) is a chronic inflammatory disease which often has debilitating and potentially life-threatening consequences. The cause of SLE is unknown and current therapies lack specificity and carry significant side-effects. We previously discovered the depletion of glutathione in lymphocytes of patients with SLE and associated this metabolic change with the elevation of the mitochondrial transmembrane potential. This study will titrate to tolerance during an initial 3 month open label period and then subjects will be randomized to one of 2 arms. It was determined by statistical analysis that each group must have 105 subjects. All subjects will be enrolled and evaluated for tolerance of NAC between dosages of 2.4 g/day and 4.8 g/day for 3 months. After A 3-month open-label dose-titration phase, SLE subjects will be randomized into 2 groups of 105 subjects either to continue the tolerated dosage of NAC or switched to equal number of placebo capsules. There will be up to seven study visits per SLE subject, including the screening and wash out visits. Visits 2-6 will be scheduled three months apart. The study will last 13 months with the wash-out visit. Each subject will donate approximately 100 ml of blood for biomarker studies at each visit. Healthy control subjects will donate blood at the same time. They will be matched to the SLE subjects by gender, age within 10 years, and ethnicity. Their blood will be used as reference for biomarker assays. There is a consent form required to participate in the phase II study.

Metformin for Osteoarthritis After ACL Surgery

Columbus, Ohio
This study is being done to find out if metformin is effective at reducing pain by delaying the onset of post-traumatic osteoarthritis (PTOA) after anterior cruciate ligament (ACL) reconstruction. This research study will compare metformin to placebo. The placebo tablet looks exactly like metformin, but contains no metformin. Placebos are used in research studies to see if the results are due to the study drug or due to other reasons. Metformin is approved by the U.S. Food and Drug Administration (FDA) to treat type II diabetes. Notably, it also has anti-inflammatory effects, suggesting it could benefit people who have an ACL injury and are undergoing ACL reconstruction.

Pimavanserin for Aggression

Columbus, Ohio
The investigators are studying how certain drugs can reduce anger outbursts in people with anger problems. In this study the investigators seek to determine if a single 34 mg (two 17 mg tablets) oral dose of the 5-HT2a receptor blocker, pimavanserin, will reduce aggressive responding in individuals with impulsive aggression (Intermittent Explosive Disorder: IED) on a laboratory task that assesses aggression (Taylor Aggression Paradigm: TAP). We will also be examining how this drug impacts hostile social cognition e.g., hostile attribution). If pimvanserin reduces aggression in this study a next step would be a placebo-controlled treatment trial of pimavanserin in study participants with IED. Participation will first involve a remote (e.g., TEAMS) screening session. If potential study participants appear eligible they will come into the lab for an in-person session where participants will complete interviews and questionnaires and have a medical evaluation (including a physical exam, electrocardiogram, and screens for alcohol and drug use). During the next study session, participants will complete a diagnostic interview and a series of questionnaires, all of which can all take place on-line. During the next two sessions (which will be in-person) participants will undergo two (2) study sessions during which study participants will be given a study drug (orally). The drug given, pimavanserin, is currently available and is known to block serotonin receptors thought to be involved in regulating anger. After participants take the study drug, study participants will complete questionnaires and computer tasks for assessment of aggression and of hostile social cognition. Each of these two in-person study sessions will take at least eight (8) hours. A final on-line session will be done to make certain the investigators have all the data required by the study protocol.

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."

AG
Paralysis PatientAge: 50

"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."

Dexmedetomidine for Congenital Heart Disease

Columbus, Ohio
The overall goal of this project is to determine the role of anesthetic management in children undergoing cardiac surgery utilizing CPB in the setting of fast tracking and early extubation. An ideal anesthetic technique would ensure abolishing or diminishing stress response as would be evident by the stress markers levels and the level of two cerebral injury biomarkers (S 100 B and NSE). This should translate to better immediate postoperative outcome and hopefully improve both the short and the long term neurodevelopmental outcome in these children. The project is prospective, randomized and blinded study. The first and second aim of the study should be conducted over 2 year period. Our long term aim will be concluded when these children reach the school age.

Ketone Ester + Nutritional Intervention for Sleep Deprivation

Columbus, Ohio
Sleep deprivation is a major problem in military populations. Some major consequences of sleep loss are inability to concentrate, poor work efficiency, and increase in errors during daily tasks. Ketogenic supplementation is speculated to alleviate some sleep deprivation issues via action of ketones. Ketones are small molecules that appear in the blood when following a ketogenic diet or consuming ketone supplements. The goal of this project is to find out if diet and/or ketones can improve sleep deprivation detriments over 5 days of sleep restriction (-50% from habitual sleep).

Radiosurgery for Spasticity

Columbus, Ohio
A scientific study is being done to test a special treatment for people who have spasticity or tight muscles. This treatment is called "stereotactic radiosurgery dorsal rhizotomy." It uses very accurate beams of radiation to target certain nerves in the back to help loosen up the muscles. In this study, people are put into two groups by chance: one group gets the real treatment, and the other group gets a "fake" treatment that doesn't do anything. This fake treatment is called a "sham." Doing this helps make sure the study is fair and the results are true. After the people in the study get their treatment, the researchers will watch and see how they do. They will check if their muscles are less stiff and if they have any side effects. By looking at the results from both groups, the researchers can find out if the special treatment really helps people with spasticity. Patients who got the "fake" treatment will be eligible to receive the "real" treatment after 6 months.

How Do Clinical Trials Work?Are Clinical Trials Safe?What Can I Expect During a Clinical Trial?

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 KarXT + KarX-EC for Alzheimer's Disease, Ketone Ester for Frail Elderly and Pimavanserin for Aggression to the Power online platform.
