We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.
The incidence of Duchenne Muscular Dystrophy (DMD) is approximately 1 in 3.500 male newborns. During its progression there is loss of mobility, swallowing difficulties and a significant reduction in respiratory capacity. Due to the severity and consequences, is inevitable the need for a caregiver, that normally rely the mother.
Duchenne Muscular Dystrophy (DMD) is inherited neuromuscular disorders due to mutation in the gene that encodes critical muscle protein called dystrophin. Currently, there is no effective treatment option for the disease. A pharmacological approach by promoting mRNA translation regardless of the presence of premature stop codons by nonsense mutation, called the readthrough strategy, has been developing recently for DMD with nonsense mutation. NPC-14 is a candidate compound for the readthrough strategy, since effective readthrough activities were demonstrated in nonclinical studies. This study is a phase II study designed to assess safety, tolerability, and efficacy of NPC-14 in ambulant DMD patients with nonsense mutation that were confirmed by whole genome analysis. These goals will be accomplished by monitoring adverse events by physical examination, cardiac, pulmonary, auditory, balance, and laboratory tests as safety endpoints, and dystrophin expression in muscle biopsy as primary efficacy endpoint, muscle function (NSAA, timed test, muscle strength (QMT, MMT) , dairy activities by lifecorder), and biomarkers as secondary efficacy endpoints. The study is a randomized, double blind, placebo-controlled study in 21 DMD patients. After screening, eligible patients are allocated dynamically to weekly NPC-14 or a placebo (saline) in a 2:1 ratio and will receive study drugs for 36 weeks.
The purpose of the extension phase of this study is to determine whether Drisapersen is effective in the treatment of boys with Duchenne muscular dystrophy resulting from a mutation thought to be corrected by exon 51 skipping.
Muscular dystrophy is a group of disorders that are characterized by progressive muscle weakening and loss of muscle mass, caused by defects in muscle proteins. Muscular dystrophy is almost always inherited disorders, and so far, no curative treatments exist. Previous studies have shown that endurance training significantly improves fitness and self-assessed muscle function in a variety of muscular dystrophies. In this study, we wish to investigate whether patients with Bethlem myopathy (a specific form of muscular dystrophy) also benefit from endurance training. The study consists of two test days, a 10-week training period and five blood tests. Patients will be required to train, three times per week, for 10 weeks, on a bike ergometer with a specific training intensity, under pulse rate monitoring. The training period will be flanked by two test days, where we will determine, and compare the patients' muscle strength and fitness level, from before to after the training program. The patients conditioning level will be determined from a 15 minute cycle ergometer test and patients will undergo three functional tests to determine their functional muscle strength. We will as a safety measure analyze blood tests before, during and after the training program for the muscle enzyme creatine kinase (an indicator of muscle damage) and through adverse effects as reported by patients during weekly telephone-consultations with the Principal investigator. We anticipate, that Bethlem myopathy patients will have a similar rise in fitness level and functional muscle strength, as that seen in patients with other forms of muscular dystrophy, who undertake a similar training program.
This is a single arm, open-label continued access protocol of drisapersen for the treatment of male subjects with Duchenne muscular dystrophy (DMD) having dystrophin mutations correctable by drisapersen-induced DMD Exon 51 skipping. The purpose of this continued access protocol is to offer pre-approval access to drisapersen for the treatment of subjects with DMD who previously participated in eligible drisapersen studies. The protocol will collect safety data required to assure subject safety and periodic efficacy data on muscle function.
By supplying an adequate amount of calcium and vitamin D with the addition of weekly bisphosphonate, the investigators will be able to increase bone mass and decrease the incidence of fragility fractures in these children with muscular dystrophy. The investigators think this treatment will also decrease the intensity of pain frequently present in these patients and slow the progression of scoliosis.
The primary objective of this investigation is to assess the effectiveness of transcutaneous electrical nerve stimulation applied using VECTTOR to reduce the symptoms of Duchenne Muscular Dystrophy and reduce the impact of DMD upon the participants' quality of life. The primary outcome measures will include: 1. increased muscle strength, 2. increased range of joint motions and 3. improved sleep parameters of ASI, N3 and REM.
The main purpose of this study is to determine if tadalafil can slow the decline in walking ability of boys who have Duchenne muscular dystrophy (DMD). The study will also assess the safety of tadalafil and any side effects that might be associated with it in boys who have DMD. Participants will receive study treatment (tadalafil or placebo) for the first 48 weeks of the study, and can then continue into an open label extension (OLE) that consists of two periods during which all participants will receive tadalafil. In OLE period 1, all participants will receive tadalafil for 48 weeks. Participants completing OLE period 1 will continue into OLE period 2 and will receive tadalafil for at least another 48 weeks.
