Application of Botulinum Toxin Type A in Salivary Glands in the Treatment of Drooling in Patients With Cerebral Palsy

Cerebral Palsy Clinical Trial

Official title: Phase 2/3 Application of Botulinum Neurotoxin Type A in Salivary Glands as a Treatment of Chronic Drooling in Patients With Cerebral Palsy: A Controlled Clinical Trial.

Status Active, not recruiting

Clinical Trial Summary

The purpose of this study is to evaluate the safety and efficacy of botulinum toxin-A in salivary glands as a treatment for decrease drooling in patients with cerebral palsy and evaluate the long-term effects and tolerance . To assess whether patients with cerebral palsy have hypersalivation comparing with patients without treatment and healthy volunteers and if botulinum toxin may reduce the volume of drooling without altering the swallowing function.

Clinical Trial Description

Patients with cerebral palsy (CP) and other neurological diseases ( Parkinson´s disease (PD), bulbar amyotrophic lateral sclerosis, neurodegenerative diseases, idiopathic hypersalivation, head and neck carcinomas, etc) frequently have lifelong issues with oral motor control that may present as eating, drinking difficulties, drooling and/or speech problems.

Inadequate saliva control occurs in approximately 30% of patients with CP. Drooling usually caused by swallowing dysfunction and can lead to choking, salivary aspiration, pneumonia, chest infections,chronic irritation of the facial skin, and /or dehydration, in some cases the person loss of self esteem and impede community inclusion.

Numerous therapies, anticholinergic medication, surgery, etc, have all been used to reduce drooling with varying side effects and degrees of success, but none with optimal results.

Systemic anticholinergics may reduce salivary secretion but are frequently not tolerated by the patients because they have multiple side effects. Recently Botulinum toxin type A has been used in the treatment of sialorrhea, in clinical studies have found that botulinum toxin type-A may have a good response with fewer side effects. ;
