Sildenafil for Traumatic Brain Injury

Philadelphia, Pennsylvania
Traumatic Cerebral Vascular Injury (TCVI) is a common consequence of traumatic brain injury (TBI), including mild TBI (mTBI). TCVI is associated with poor recovery after TBI in animal models. TCVI can be measured non-invasively in humans, and therapies targeting TCVI are attractive candidates to ameliorate the consequences of TBI. Sildenafil potentiates nitric oxide (NO) dependent vasodilatation and is approved by the Food and Drug Administration (FDA) for the treatment of erectile dysfunction and primary pulmonary hypertension. In pre-clinical models of stroke, sildenafil improves cerebral blood flow (CBF), promotes, angiogenesis, neurogenesis and improves recovery. In an initial Phase 2a trial (NCT01762475) of sildenafil in patients with chronic moderate to severe TBI, the investigators found that low dose sildenafil (25 mg BID) therapy is safe and well tolerated, that a single dose of sildenafil 50 mg potentiates CVR in areas of the brain with dysfunctional endothelium, and that CVR is a reliable diagnostic marker of TCVI and has potential as a pharmacodynamic and predictive biomarker. In this proposal, the investigators will conduct a randomized clinical trial to determine the optimal PDE5 inhibitor dose to improve or normalize microvascular function (as measured by the change in CVR measurements before and after a single dose of sildenafil, or ΔCVR) using a range of sildenafil citrate doses: 20, 40, 80 mg) in chronic TBI patients. The investigators will also test the safety and tolerability of the same dose ranges of chronic (4-week) thrice daily sildenafil or placebo administration in chronic TBI patients and explore its effects on chronic symptoms and clinical outcomes.

Contemporary left ventricular assist device (LVAD) therapy improves survival during advanced heart failure but vascular aging develops rapidly leading to major adverse events including stroke and bleeding in nearly half of patients. In this study, the study team aims to investigate whether sildenafil pharmacotherapy, which has anti-fibrotic effects, can reduce vascular aging during LVAD support. An aim of this study is to compare changes in small blood vessels in the gastrointestinal tract between participants receiving sildenafil or placebo. Video capsule endoscopy (VCE) will be used to assess these changes in small blood vessels.

Around the time of birth, some babies experience a condition called asphyxia, which means that their brain and other organs do not receive enough blood and/or oxygen to work properly. This life-threatening condition accounts for nearly 1 out of 4 deaths of all babies around the world, and often leads to severe brain damage, cerebral palsy, epilepsy, and trouble with learning and functioning in everyday life. At this time, no treatment is available to repair the brain damage caused by asphyxia. Excitingly, a drug called sildenafil (Viagra®) is already given safely to babies who suffer from increased blood pressure in their lungs' vessels. Recent studies using a laboratory model of asphyxia at birth suggest that sildenafil may also repair the brain damage caused by asphyxia. Similarly, recent small studies have shown that it is both feasible and safe to give sildenafil to human babies, who suffered from asphyxia at birth. These studies also highlight the first promising signs that sildenafil may improve how the brains of these babies work, which is consistent with the abovementioned laboratory studies. On the basis of these previous researches, the investigators predict that sildenafil can repair the damage to a baby's brain. The investigators will test whether sildenafil can be safely given to a large group of human babies who suffer from asphyxia at birth, and will confirm whether sildenafil improves or not how their brains and hearts/lungs work. This project will enable to determine whether sildenafil is a promising treatment for repairing brain damage in babies who suffer from asphyxia at birth. This project may also provide new solutions for these babies to improve their future life.

The investigators goal is to develop medical treatments for stress/mixed urinary incontinence. Sildenafil has been shown to improve blood flow as well as muscle mass and strength and to decrease muscle fatigue. The investigators believe that it will improve muscular atrophy in the pelvic floor, thus improving symptoms of urinary incontinence related to pelvic floor dysfunction.

Congenital diaphragmatic hernia (CDH) occurs in approximately 1 in 3000 US live births, similar to the incidence seen within the Utah Birth Defects cohort. The diaphragmatic defect compromises lung growth and alters pulmonary vascular development. This is reflected postnatally as respiratory failure, pulmonary hypertension (PH) and overall cardiopulmonary dysfunction, particularly post-repair. Currently, optimal management of post-repair PH remains poorly investigated. Sildenafil citrate is a highly selective phosphodiesterase-5 inhibitor that increases cGMP levels, leading to smooth muscle relaxation and an anti-proliferative effect within the pulmonary vasculature. It is used off-label for many neonatal PH disorders, including PH associated with bronchopulmonary dysplasia and idiopathic persistent PH. Most neonates with CDH born within the Mountain West referral basin are managed at a quaternary care center, Primary Children's Hospital (PCH). Of these neonates with PH, approximately 25% have been treated with off-label sildenafil. However, neither the PCH clinical care group nor others have developed/published a standardized approach for either initiating or discontinuing sildenafil therapy in this group of patients. Thus, the aim of this study is to assess the safety and effectiveness of sildenafil therapy for PH in neonates with CDH within the Utah cohort. Given the relatively short-term outcome and small sample size for this trial, the plan is to use this data to support a larger multicenter randomized trial targeting long-term cardiopulmonary outcomes of infants with CDH and post-repair PH.

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."

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 Sildenafil for Vascular Disease, Sildenafil for Traumatic Brain Injury and Sildenafil for Neonatal Encephalopathy to the Power online platform.
