Facioscapulohumeral muscular dystrophy (FSHD) is the second most common adult muscular dystrophy in the world with a global prevalence of ~4:100,000. Clinically, patients with FSHD experience progressive weakness, muscle wasting, fatigue, and respiratory decline. As adult patients with FSHD age, they frequently develop difficulty walking or lose the ability to ambulate due to profound weakness and muscle atrophy. Currently, there are no therapies that have been demonstrated to reverse or even slow the progressive symptoms associated with FSHD. Large scale clinical trials have found that testosterone combined with recombinant human growth hormone (rHGH) (combination therapy) is well tolerated and effective in synergistically improving respiratory function, lean body mass, protein synthesis, strength, and aerobic endurance in healthy adult human populations. Both testosterone and rHGH are readily available and approved for human use but have never been formally studied together in a muscular dystrophy population. We propose a 36-week, proof-of-concept clinical study of the safety and tolerability of daily rHGH combined with biweekly testosterone injections in men with FSHD. All participants will be serially and closely monitored during a 24 week period of combination therapy followed by a 12 week washout period. Safety assessments will include monitoring for medication side effects, laboratory abnormalities, physical exam changes, and EKG alterations. As a secondary objective, we will examine the pharmacokinetic effects of combination therapy on lean body mass and serum biomarkers. Participants will also have serial assessments of their ambulation, strength, physical function, patient-reported disease burden, and respiratory function. Ultimately, this study will generate extensive data regarding the clinical safety, pharmacokinetics, and change in body composition and clinical function associated with combination therapy in a predefined FSHD population.

面肩肱型肌营养不良症（FSHD）是第二个最常见的成人肌营养不良症， 全球患病率约为4：100，000。临床上，FSHD患者经历进行性 虚弱、肌肉萎缩、疲劳和呼吸下降。随着FSHD成年患者年龄的增长，他们经常 行走困难或因极度虚弱和肌肉萎缩而丧失行走能力。 目前，还没有任何疗法被证明可以逆转或甚至减缓进展， 与FSHD相关的症状大规模的临床试验发现，睾酮与 重组人生长激素（rHGH）（联合治疗）耐受性良好，有效， 协同改善呼吸功能、瘦体重、蛋白质合成、力量和有氧运动 健康成年人的耐力。睾酮和rHGH都是现成的， 批准用于人类使用，但从未在肌营养不良人群中一起正式研究。 我们提出了一项为期36周的概念验证临床研究的安全性和耐受性的每日rHGH结合 每两周注射一次睾丸激素所有参与者都将受到连续和密切的监测 在24周的联合治疗期间，随后是12周的清除期。安全性评估 将包括监测药物副作用、实验室异常、体格检查变化和EKG 改变。作为次要目的，我们将检查联合治疗对以下药物的药代动力学影响： 瘦体重和血清生物标志物。参与者还将对他们的ambership进行一系列评估， 力量、身体功能、患者报告的疾病负担和呼吸功能。最终，这项研究将 生成有关临床安全性、药代动力学和身体成分变化的广泛数据， 在预定的FSHD人群中与联合治疗相关的临床功能。
