Randomized Study of Albuterol in Patients With Facioscapulohumeral Muscular Dystrophy

Condition(s) targeted: Muscular Dystrophy, Facioscapulohumeral

Intervention: albuterol (Drug)

Phase: N/A

Status: Active, not recruiting

Sponsored by: FDA Office of Orphan Products Development

Official(s) and/or principal investigator(s):
John T. Kissel, Study Chair, Affiliation: Ohio State University

OBJECTIVES: I. Determine whether albuterol increases strength in patients with facioscapulohumeral dystrophy as measured by quantitative voluntary isometric contraction testing.

II. Determine whether albuterol increases muscle mass in this patient population as determined by 24 hour urinary creatinine excretion and dual energy x-ray absorptiometry (DEXA).

III. Examine the long term safety of albuterol in this patient population.

Study design: Treatment, Randomized, Double-Blind, Placebo Control

Detailed description: PROTOCOL OUTLINE: This is a randomized, double blind, placebo controlled study. Patients are randomized into one of three treatment groups. The first group receives placebo. The second group receives low dose albuterol orally every 12 hours. The third group receives high dose albuterol orally every 12 hours. Treatment continues for 52 weeks unless unacceptable side effects occur.

All patients return for follow up assessments at weeks 4, 12, 24, and 52.

Minimum age: 18 Years. Maximum age: 80 Years. Gender(s): Both.

Criteria:

PROTOCOL ENTRY CRITERIA:

including frontalis, orbicularis oculi, or orbicularis oris Weakness of scapular stabilizers or foot dorsiflexors Weakness of grade 2 or worse in the arm using the upper extremity grading scale No other neuromuscular diseases that may mimic the clinical presentation of facioscapulohumeral dystrophy: Ptosis or ophthalmoparesis (other than congenital strabismus) Elbow contractures Strictly unilateral weakness Dermatomyositis-like skin rash Symmetric distal sensory loss Muscle biopsy findings of mitochondrial myopathy, chronic denervation, dermatomyositis, inclusion body myositis, or congenital myopathy Electromyographic (EMG) findings of myotonia, fasciculations, or neurogenic motor unit

potentials - -Prior/Concurrent Therapy-- Endocrine therapy: No prior long term use of oral

corticosteroids for more than 1 year At least 3 months since prior use of corticosteroids No concurrent use of immunosuppressive agents Surgery: No concurrent surgeries Other: No concurrent use of sympathomimetic agents, antidepressants, or beta receptor blockers

- -Patient Characteristics-- Age: 18 to 80 Performance status: Ambulatory Cardiovascular: No
