Brief Summary
Translational studies have demonstrated reduced hyaluronidase activity in the skin of patients with systemic sclerosis. It is thought this may contribute to the progressive fibrosis seen in this disease. Several studies have demonstrated that exogenous hyaluronidase is very effective at improving systemic sclerosis associated microstomia. Therefore, this study aims to explore hyaluronidase for systemic sclerosis associated sclerodactyly.

Outcome Measures
Primary Outcomes (2)
Feasibility Assessment
The primary measures of feasibility will be study refusal rate and visit adherence during the treatment period. If the study refusal rate is more than 70% the study will be deemed unfeasible
28 weeks
Evaluate Safety
Will monitor for adverse events and serious adverse events at every 4 week visit. All will be graded using Common Terminology Criteria for Adverse Events
32 weeks
Secondary Outcomes (2)
Estimate preliminary efficacy in digital range of motion
28 weeks
Estimate preliminary efficacy based on patient reported outcomes
28 weeks
Study Arms (1)
Intradermal Hyaluronidase
EXPERIMENTALInterventions
Patients will receive monthly injections of hyaluronidase into 1 finger on each hand over a 28 week treatment period.
