Ipsen: New Surveys Show Over 80% of Patients with Spasticity and Cervical Dystonia Treated with Botulinum Toxin-A Experience Debilitating Symptom Recurrence

Regulatory News:


Ipsen (Euronext: IPN; ADR: IPSEY) today presents the results of two patient surveys. The surveys involved over 400 respondents from five countries, living with spasticity or cervical dystonia and receiving botulinum neurotoxin type A (BoNT-A) injections. The results show that over 80% of respondents experienced debilitating symptom recurrence, and revealed that a lack of long-lasting symptom control between injections has a profound impact on the personal and professional lives of patients.1-4


"The results from these two important patient surveys provide significant insight into the real-life burden of the two conditions; however, they also highlight a worrying disconnect between patientsa?? treatment expectations and their actual experience. The findings, which build on our growing understanding of spasticity and cervical dystonia, provide us with the potential to unlock meaningful changes in clinical practice,a?? said Dr Alberto Esquenazi, Department of Physical Medicine and Rehabilitation, Gait and Motion Analysis Laboratory, MossRehab and Albert Einstein Medical Centre, U.S. and lead investigator on the spasticity survey.


The first survey1,2 investigated the burden of spasticity on patientsa?? lives. Of the 210 respondents from France, Germany, Italy, the U.K., and the U.S., 83% reported that symptoms of spasticity returned between two sessions of BoNT-A, with 59% of these patients experiencing that return within three months of their last treatment. Symptom recurrence significantly impacted patientsa?? quality of life, including sleep, relationships, performance of daily tasks and working lives. In addition, 47% of working patients reported being unable to work when symptoms re-emerge and 45% of working patients felt less efficient at work than before.1,2


The second survey3,4 adopted a similar approach, analyzing data from 209 respondents with cervical dystonia from across France, Germany, Italy, the U.K., and the U.S. Of the respondents, 88% reported the reappearance of pre-existing symptoms between BoNT-A injections. The majority of working respondents reported a significant impact on their professional life, with 66% stating that they did not feel comfortable at work and 66% did not feel as efficient at work as usual. Patientsa?? personal lives were also significantly compromised by their symptom recurrence, with an impact on their ability to socialize, sleep well, drive, or perform daily tasks.3,4
