Clinical Trial Summary

This study will evaluate the use of botulinum toxin for microstomia (also known as reduced oral aperture) in scleroderma patients. Botox is a neurotoxin that functions as a paralytic by preventing the release of acetylcholine to inhibit muscle contracture and decrease fibrosis by decreasing differentiation of fibroblasts to myofibroblasts, decreasing expression of collagen, and increasing expression of matrix metalloproteinase1-3. The study will include three arms: the temporomandibular joint (TMJ) group who will receive injections of Botox to the masseter, the perioral group who will receive injections of Botox around the lips, and a control group who will receive no treatment for ROA. Outcome measurements will include measurement of oral aperture size through measurement inter-labial distance and between the upper and lower lips and the inter-incisal distance, patient satisfaction via a Skindex16 survey, mouth disability via the Mouth Handicap in Systemic Sclerosis Scale (MHISS), and patient and physician satisfaction using the Visual Analogic Scale (VAS). The maximum number of subjects to be consented for this study is 30. The study is expected to last four months per subject from time of consent to last clinical evaluation. Conditions that may result in a subject exiting the study prior to completion date include non-compliance, withdrawal of consent, or safety concerns such as adverse events as a result of treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes in inter-labial distance	Inter-labial distance is defined as the distance between the upper and lower lip at maximum mouth opening. Distance will be measured using digital calipers by the same operator	This will be measured at baseline before treatment, 2 weeks after treatment, and 3 months after treatment.
Primary	Changes interincisal distance	Interincisal distance is defined by the didistance between upper and lower incisor at maximum mouth opening. Distance will be measured using digital calipers by the same operator	This will be measured at baseline before treatment, 2 weeks after treatment, and 3 months after treatment.
Primary	quality of life via a Skindex16 survey	This is a patient quality of life survey using the skindex 16 survey form.	This information will be collected at baseline before treatment, 2 weeks after treatment, and 3 months after treatment.
Secondary	Changes in the inter-commissural distance	Inter-commissural distance is defined by the distance from corner to corner at the angle of the lip (also known as the oral commissures). Distance will be measured using digital calipers by the same operator.	This will be measured at baseline before treatment, 2 weeks after treatment, and 3 months after treatment.]
Secondary	Changes in the Mouth Handicap in Systemic Sclerosis Scale (MHISS)	Mouth disability will be assessed via the Mouth Handicap in Systemic Sclerosis Scale (MHISS). MHISS range from 0 to 48 with 48 being worse disability	This will be measured at baseline before treatment, 2 weeks after treatment, and 3 months after treatment.]
