The goal of this clinical trial is to better understand the effects of intrathecal baclofen (ITB) on children with dystonic cerebral palsy (CP). The main questions this study aims to answer are: (1) Determine if ITB reduces dystonia while identifying other potential benefits, (2) Identify the characteristics of children with the best response to ITB (3) Develop a holistically representative composite outcome measure for dystonic CP. This study will evaluate patient improvement by using a standardized titration, or medication management, protocol to gradually increase the childs ITB dosages over a 12-month period until they achieve maximum benefit with minimal to no side effects. This titration protocol mimics what is currently done through routine care but with more precision. This study will also directly measure the global effects of ITB, taking into account spasticity, known dystonia triggers (e.g. pain), and patterns of CNS injury that cause dystonia. Participants will: 1. Complete a total of 4 additional clinic visits outside usual care. These appointments will be with physical and occupational therapists as well as the study PI to complete evaluations for dystonia, spasticity, and function. 2. Complete several questionnaires at these visits. The total duration of the study for an individual child will be 12 months.

The purpose of this study is to measure the effects of non-regular temporal patterns of deep brain stimulation (DBS) on motor symptoms and neural activity in persons with Parkinson's disease (PD), essential tremor (ET), dystonia or multiple sclerosis (MS). These data will guide the design of novel stimulation patterns that may lead to more effective and reliable treatment with DBS. These data will also enable evaluation of current hypotheses on the mechanisms of action of DBS. Improving our understanding of the mechanisms of action of DBS may lead to full development of DBS as a treatment for Parkinson's disease and may lead to future applications of DBS.

Valbenazine for Torticollis

Richmond, Virginia
The most common form of idiopathic dystonia is adult-onset cervical dystonia (CD), a focal form of dystonia affecting the muscles of the neck. CD is often associated with pain and limited range of motion, and frequently leads to reduced quality of life and disability. Effective long-term treatment options are extremely limited. Recurring botulinum neurotoxin (BoNT) injections can ease the symptoms of CD, but they frequently provide only partial relief and can be associated with intolerable side effects. Deep brain stimulation can be used to treat more severe cases of CD, but this neurosurgical procedure is invasive, on average only about 50% effective and may lead to serious adverse effects. Novel treatment approaches for CD are desperately needed to alleviate symptoms and improve the quality of life for the many who suffer from this chronic and disabling neurological disorder.

Researchers want to test a procedure called deep brain simulation (DBS) to treat focal hand dystonia (FHD). A device called a neurostimulator is placed in the chest. It is attached to wires placed in brain areas that affect movement. Stimulating these areas can help block nerve signals that cause abnormal movements. Objectives: To test DBS as treatment for FHD. To learn about brain and nerve cell function in people with dystonia. Eligibility: People ages 18 and older with severe FHD who have tried botulinum toxin treatment at least twice Design: Participation lasts 5 years. Participants will be screened with: Medical history Physical exam Videotape of their dystonia Blood, urine, and heart tests Brain MRI scan Chest X-ray Neuropsychological tests: answering questions, doing simple actions, and taking memory and thinking tests. Hand movement tests Participants will have surgery: A frame fixes their head to the operating table. A small hole is made in the skull. Wires are inserted to record brain activity and stimulate the brain while they do simple tasks. The wires are removed and the DBS electrode is inserted into the hole. The neurostimulator is placed under the skin of the chest, with wires running to the electrode in the brain. They will have CT and MRI scans during surgery. Participants will recover in the hospital for about 1 week. The neurostimulator will be turned on 1 4 weeks after discharge. Participants will have regular visits until the study ends. Visits include: Checking symptoms and side effects MRI Movement, thinking, and memory tests If the neurostimulator s battery runs out, participants will have surgery to replace it.

Background: - Deep brain stimulation (DBS) is an approved surgery for certain movement disorders, like Parkinson's disease, that do not respond well to other treatments. DBS uses a battery-powered device called a neurostimulator (like a pacemaker) that is placed under the skin in the chest. It is used to stimulate the areas of the brain that affect movement. Stimulating these areas helps to block the nerve signals that cause abnormal movements. Researchers also want to record the brain function of people with movement disorders during the surgery. Objectives: * To study how DBS surgery affects Parkinson s disease, dystonia, and tremor. * To obtain information on brain and nerve cell function during DBS surgery. Eligibility: - People at least 18 years of age who have movement disorders, like Parkinson's disease, essential tremor, and dystonia. Design: * Researchers will screen patients with physical and neurological exams to decide whether they can have the surgery. Patients will also have a medical history, blood tests, imaging studies, and other tests. Before the surgery, participants will practice movement and memory tests. * During surgery, the stimulator will be placed to provide the right amount of stimulation for the brain. Patients will perform the movement and memory tests that they practiced earlier. * After surgery, participants will recover in the hospital. They will have a followup visit within 4 weeks to turn on and adjust the stimulator. The stimulator has to be programmed and adjusted over weeks to months to find the best settings. * Participants will return for followup visits at 1, 2, and 3 months after surgery. Researchers will test their movement, memory, and general quality of life. Each visit will last about 2 hours.

This is a parallel arm non-randomized dose-escalation, open-label basket exploratory phase 1 clinical trial where Mitochondrial encephalopathy, lactic acidosis, stroke-like episodes (MELAS) and Leber's hereditary optic neuropathy-Plus (LHON-Plus) participants will undergo simultaneous enrollment in two disease-based arms and receive daily oral doses of glycerol tributyrate to assess its safety and potential for efficacy using clinical, biochemical, and molecular evidence. This study will utilize a two-month baseline lead-in phase to establish and document the clinical baseline for each participant in both arms in order to compare the molecular and clinical parameters. This is clinically relevant in light of the high clinical heterogeneity among subjects affected by the same mitochondrial disease (MELAS or LHON-Plus). For ethical concerns prompted by the lack of treatment for these two intractable and progressive mitochondrial diseases, there will not be a placebo control group. Thus, each participant will act as their own control and receive oral doses of glycerol tributyrate, eliminating the need for a placebo. Considering the high clinical heterogeneity among participants affected by MELAS or LHON-Plus and some clinical divergence between MELAS and LHON-Plus, this strategy is beneficial to every enrolled participants, as each will receive the investigational drug, glycerol tributyrate. In addition, this approach will determine the subject-specific maximal optimized dose in a personalized medicine-based approach. After approval of the IRB protocol from the Institutional Review Board Data and signed consent form from all participants, this investigational basket clinical trial has three phases spanning over 20 months: * A baseline lead-in phase (2 months) to collect participant-specific baseline for clinical, biochemical, molecular and metabolic biomarkers that will be monitored throughout the subsequent dose-escalation and clinical phases. * A dose-escalation phase (6 months) to determine the participant-specific maximum tolerated dose (MTD) during which participant-specific clinical and biochemical biomarkers are collected every month. * A clinical phase at a fixed subject-specific MTD dose (12 months) to collect participant-specific clinical, biochemical, molecular and metabolic biomarkers and to perform three scheduled skin biopsies: at the outset, mid-point, and the end of this clinucal phase. We have planned for a 12-month-long clinical phase at a fixed participant-specific MTD considering the absence of reliable predictors that makes idiosyncratic disease-specific symptoms for MELAS and LHON-Plus impossible to forecast among participant for assessing the potential efficacy of glycerol tributyrate by monitoring clinical symptoms specific for each disease. During the 12-month-long time-frame, disease-specific clinical symptoms will be collected as preliminary evidence of efficacy of glycerol tributyrate using disease-specific biomarkers. Finally, discharge procedure during which the clinical investigator will record non-serious adverse events or serious adverse events for 7 or 30 days, respectively, after the last day of study participation.

Prolonged labor is usually managed with continuous oxytocin infusion. "Oxytocin rest" has been proposed as a strategy to resolve protracted labor in patients who have received continuous oxytocin without progress. This strategy involves discontinuing oxytocin then restarting infusion after a period of time, under the theory that washout of the oxytocin receptor will strengthen uterine contractions to improve labor progress. "Oxytocin rest" is performed on labor and delivery units across the United States. Yet, there is no randomized or prospective data to support the practice. The purpose of this study is to assess whether oxytocin rest of 60 minutes in patients with prolonged labor reduces risk for cesarean delivery.

Frequently Asked Questions

How much do Dystonia 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 Dystonia 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 Dystonia 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 for Dystonia 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 Dystonia 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 Dystonia clinical trials ?

Most recently, we added Voice Restoration Device for Loss of Voice, Sleep Disturbance Analysis for Gastrointestinal Cancer and Mindfulness Intervention for Blood Cancers to the Power online platform.
