|Condition or disease||Intervention/treatment||Phase|
|Sialorrhea Cerebral Palsy||Biological: BOTULINUM NEUROTOXIN TYPE-A||Phase 2 Phase 3|
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.

|Estimated Study Completion Date :||November 2012|
Experimental: Botulinum Toxin
Botulinum Toxin type-A
Biological: BOTULINUM NEUROTOXIN TYPE-A
Botulinum toxin type A / First infiltration: 25U in each salivary gland=100 U in Parotid and submandibular glands. 24 weeks after first infiltration is a Second infiltration with 50U Botulinum toxin type -A 25 U in each salivary gland only in parotid glands.
No Intervention: Control Treatment
- Asses drool quantification pre and post-infiltration in submandibular and parotid glands with BoNT-A [ Time Frame: Change from baseline in drooling0,4,8,12,16,20,24 weeks post infiltration/baseline, and again second infiltration only in parotid glands ]
Drool quantification using a pre-and post injection "drool rating scale" dental roll weights, drool quotient.
Safety evaluate. The proportion of patients with a good response according to the criteria, defined response during treatment or follow-up.
- Asses at what period of time after infiltration occurs the maximum response in decreased drooling, and whether Botulinum toxin-A reduce the volume of drooling without altering the swallowing function. [ Time Frame: every 4 weeks ( after each infiltration) ]Salivary flow expressed in ml/ min evaluated in diferent subtypes of cerebral palsy compared before and after infiltration and compared with control group without infiltration and control group of healthy volunteers.
