SIALORRHEA CAN NEGATIVELY
IMPACT PATIENTS’ QUALITY
OF LIFE AND CONTRIBUTE
TO SOCIAL ISOLATION.1,2
XEOMIN® is indicated in adults for the symptomatic treatment of:3

- blepharospasm and hemifacial spasm,
- cervical dystonia of a predominantly rotational form
(spasmodic torticollis), - spasticity of the upper limb and
- chronic sialorrhea due to neurological disorders.
XEOMIN® is the first and only pharmaceutical product licensed for the treatment of chronic sialorrhea due to neurological disorders in adults.3
XEOMIN® (botulinum neurotoxin type A) is recommended by NICE, within its marketing authorisation, as an option for treating chronic sialorrhea caused by neurological conditions in adults. It is recommended only if the company provides it according to the commercial arrangement.4

XEOMIN® showed a significant reduction in salivary flow rate vs placebo5
In SIAXI, a prospective, placebo-controlled, randomised, double-blind, parallel-group phase III study (n=184), XEOMIN® demonstrated:
Significant reduction in salivary flow by up to 33% vs. placebo5
The coprimary endpoints were the change in unstimulated salivary flow rate (uSFR) from study baseline to week 4, and the patients’ Global Impression of Change Scale (GICS) score at week 4.
CHANGE FROM BASELINE IN uSFR
Adapted from Jost WH et al. 2019.
- Study includes adult patients with Parkinson's, Atypical parkinsonism, Stroke or Traumatic Brain Injury (TBI)5
- Sustained reductions in salivary flow were observed with repeat treatments over 64 weeks6
- Significant improvements in patients’ perception of functioning vs. placebo at week 4 (p=0.002)5
XEOMIN® has an established tolerability and safety profile5,7
- Generally well-tolerated in the initial main study phase up to 16 weeks7
Most common treatment-emergent adverse events (TEAEs)
TEAEs were defined as adverse events (AEs) with onset or worsening at or after the 1st injection of XEOMIN® or placebo up to and before 1st injection of extension period (EP) or in case of discontinuation before EP up to and including 16 weeks after 1st injection or date of last study visit, whichever was later. | Placebo (n=36) | XEOMIN® 75 U (n=74) | XEOMIN® 100 U (n=74) |

- The percentage of patients with AEs and treatment-related AEs in the XEOMIN® group was similar to
those observed with placebo. There were no unexpected AEs with XEOMIN® 5 - Furthermore, XEOMIN® was generally well-tolerated in the extension phase up to 64 weeks8
- No unexpected safety concerns were identified during three additional cycles of XEOMIN® 8
XEOMIN® is injected directly into the salivary glands providing targeted treatment of sialorrhea4
