Information provided by:	The University of Texas Health Science Center at San Antonio
ClinicalTrials.gov Identifier:	NCT00125203

Purpose

The purpose of this study is to determine the safety and efficacy of Myobloc in ALS patients who are having excessive drooling.

The primary goal of the study is to determine if the patient perceives a benefit from the Myobloc in controlling excessive drooling.

Primary Outcome Measures:

Global impression of change by subject at eight weeks post injection

Secondary Outcome Measures:

Patient's subjective assessment of benefit
Change in volume of saliva produced over five minutes (measured with funnel and tube)
ALS Functional Rating Scale (ALSFRS)
Caregiver's subjective assessment of benefit
Change in anticholinergic medication doses and number of times per day suction is used
SEQOL-DW
Duration of benefit
Assessment of treatment assignment (final visit only)
Global assessment of change by investigator

Estimated Enrollment:	20
Study Start Date:	July 2003
Estimated Study Completion Date:	August 2007

Detailed Description:

The secondary goals of this study are to:

determine the safety of bilateral injections of Myobloc into the parotid and submandibular glands as an effort to control sialorrhea;
determine by objective measures if the Myobloc injection decreases the saliva produced;
determine caregiver perceived benefit from Myobloc injection.

Eligibility

Ages Eligible for Study:	21 Years to 85 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Diagnosis of probable or definite ALS based on current World Federation of Neurology criteria
Between the ages of 21-85, inclusive
Sialorrhea refractory to treatment with at least two anticholinergic medications OR has been intolerant of anticholinergic medications due to side effects
Capable of giving informed consent
Must be able to attend all study visits

Exclusion Criteria:

Patient has any uncontrolled significant medical, psychiatric or neurological disease (other than ALS) over the past 30 days
History of ongoing substance abuse
History of non-compliance with treatment in other experimental protocols
Cannot provide informed consent or comply with evaluation procedures
Has received any form of botulinum toxin in the past for any indication
Women who are pregnant, lactating, or of child bearing potential not using an adequate form of birth control
Currently being treated with coumadin
Forced vital capacity (FVC) <40% of predicted unless the tidal volume is > 600cc, as patients with significant bulbar weakness may show a falsely low FVC due to bulbar muscle spasticity
