Active clinical trials for "Prader-Willi Syndrome"

PATH for PWS is a study to help researchers better understand serious medical events in PWS over a 4-year period, as well as evaluate how PWS-related behaviors change over time. The data from this study is intended to inform the development and clinical trial design of potential new treatments.

Abnormal body composition with increased body fat mass and decreased lean body mass has been found in adults with Prader-Willi syndrome (PWS), contributing to reduced physical capacity and impairment. The aim of this study was to investigate whether progressive elastic band resistance training can improve physical motor performance and regional body composition in adults with PWS.

The Polyvagal Theory focuses on how function and structure changed in the vertebrate autonomic nervous system during evolution. The theory is named for the vagus, a major cranial nerve that regulates bodily state. As a function of evolution, humans and other mammals have a "new" vagal pathway that links the regulation of bodily state to the control of the muscles of the face and head including the middle ear muscles. These pathways regulating body state, facial gesture, listening (i.e., middle ear muscles), and vocal communication collectively function as a Social Engagement System (SES). Because the Social Engagement System is an integrated system, interventions influencing one component of this system (e.g., middle ear muscles) may impact on the other components. Individuals with Prader-Willi Syndrome (PWS) exhibit many behaviors that are consistent with a compromised Social Engagement System. Atypical function of the Social Engagement System results in problems associated with state regulation (e.g., impulsivity, tantrums, and difficulty with change in routine), ingestion (e.g., difficulties in sucking at birth, hyperphagia), coordination of suck/swallow/breathe, intonation of vocalizations, auditory processing and hypersensitivity, and socialization. We propose to confirm that several features of the behavioral phenotype of PWS may be explained within the context of a dysfunctional SES (Specific Aim I), which may be partially rehabilitated via an intervention designed as a 'neural exercise' of the SES (Specific Aim II). Specific Aims: Aim I: To demonstrate that children with PWS have atypical regulation of the SES. We hypothesize these effects will be manifested by dampened vagal regulation of the heart (low parasympathetic tone); poor middle ear muscle regulation resulting in auditory hypersensitivities and poor auditory processing; lack of voice intonation (prosody), and difficulties in accurately detecting the emotions of others. Aim II: To demonstrate the effectiveness of the Listening Project Protocol (LPP) in decreasing the atypical features of the SES in adolescents with PWS. We hypothesize that individuals who complete the LPP will have improved vagal regulation of the heart, improved middle ear muscle regulation, increased voice intonation and improved ability to accurately detect the emotions of others.

The investigatiors propose to confirm that several features of the behavioral phenotype of PWS may be explained within the context of a dysfunctional SES, which may be partially rehabilitated via an intervention designed as a 'neural exercise' of the SES (i.e., the Safe and Sound Protocol, "SSP"). Specific Aims: Aim I: To demonstrate the effectiveness of the Safe and Sound Protocol (SSP) on improvement of social and regulation behaviors in individuals with PWS. Aim II: To evaluate a new methodology for collecting and evaluating vocal samples for analyses of prosody, one of the indices of the functioning of the SES.

This is a Phase 3 open-label extension (OLE) study in patients diagnosed with Prader-Willi Syndrome (PWS) who completed the Maintenance Period of the randomized, placebo-controlled Phase 2/3 study SCOUT-015. The primary objective of this study is to assess the long-term safety and tolerability of RAD011.

The hyperghrelinemia of children with PWS provides a unique model by which to explore the hormonal and metabolic effects of orexigenic hormones in normal and pathologic conditions. An important question to be addressed by this proposed research includes the macro-nutrient regulation of ghrelin and PYY in obese children and children with PWS. As ghrelin antagonists are considered potential future anti-obesity agents, it is essential to gain understanding of the developmental, nutritional and hormonal regulation of this important orexigenic hormone in children.

The primary objective of this study is to monitor the long-term safety of DCCR in PWS patients.

This is a placebo-controlled clinical trial to assess the utility of Guanfacine Extended Release (GXR) in the management of patients with Prader Willi Syndrome (PWS) who have significant aggression or self-injury. The purpose of this trial is to establish the safety of GXR with a specific focus on metabolic effects.

This study will evaluate the safety and efficacy of Tesomet (tesofensine + metoprolol) in subjects with PWS.

The main research question this protocol aims to answer is whether treatment with growth hormone will impact body composition, quality of life, and energy balance in PWS adults, and if there is a loss of effects after cessation of treatment for at least 12 months.
