About this study
The study tests the notion that patients suffering from certain types of congenital myasthenic syndromes are benefitted by the use of Albuterol at doses used in clinical practice.
Read the detailed description
The aim of the proposal is to evaluate the effects of albuterol, an adrenergic agonist, in the treatment of congenital myasthenic syndromes (CMS). Over the past 2 decades I found that some CMS patients refractory to or worsened by cholinergic agonists, namely those suffering from defects in acetylcholinesterase (AChE) or Dok-7, respond to ephedrine, a medication used for over half-a-century in the treatment of autoimmune myasthenia gravis. After ephedrine became unavailable, I treated the same type of patients with albuterol in doses ranging from 4 mg daily to twice daily for adults; the dose for children 6 to 12 years is 2 mg two or three times daily; the dose for children 2 to 6 years is 0.1 mg/kg/day (maximum 2 mg) three times daily. Evaluation of the effects of the medications are based on the Table shown below.

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Name: Efficacy of albuterol in the treatment of congenital myasthenic syndromes (time frame: 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jan 2016.
