Brief Summary
This study aims to assess whether or not a single injection schedule of botulinum toxin A (BTX-A) in both hands improves Raynaud phenomenon (RP) secondary to systemic sclerosis (SSc) better than a placebo at 4, 12 and 24 weeks after the treatment. This study's hypothesis is that the number of RP attacks per week from baseline to 4 weeks after treatment is significantly lower in the group treated with BTX-A than in the control group treated by the placebo. Furthermore, BTX-A in both hands is expected to improve both symptomatic (attack frequency, digital ulcer healing) and functional (pain, hand function, quality of life) symptoms of RP secondary to SSc more than placebo.

Outcome Measures
Primary Outcomes (1)
Absolute change from baseline in the number of RP attacks per week at 4 weeks
Comparison between the 2 groups of the change (absolute) from baseline in the number of RP attacks per week at 4 weeks. An attack is defined as an episode of pallor or cyanosis (with or without pain, tingling or numbness). Subjects will keep a daily record of the number of RP attacks they experienced per day and the duration of each attack, from Day -14 to Day 0 (+/- 4 days) and from Day 14 to Day 28 ( +/- 4 days)
4 weeks
Secondary Outcomes (9)
Absolute change from baseline in the number of RP attacks per week at 12 and 24 weeks
24 weeks
Comparison between the 2 groups at 4, 12 and 24 weeks of follow-up after the treatment of the percentage of digital ulcers with complete healing
24 weeks
Comparison between the 2 groups at 4, 12 and 24 weeks of follow-up after the treatment of the number of new digital ulcers.
24 weeks
Comparison between the 2 groups at 4, 12 and 24 weeks of follow-up after the treatment of the change in Raynaud's pain score.
24 weeks
Comparison between the 2 groups at 4, 12 and 24 weeks of follow-up after the treatment of the change in Raynaud's Condition Score.
24 weeks

Study Arms (2)
" BTX-A" group
EXPERIMENTAL* BOTOX® solution * Saline serum * lidocaine/prilocaine cream * Nitrous oxide/oxygen (50%/50%) Intervention Description : * BOTOX 100 UNITES (Allergan, Courbevoie, France, and São Paulo, Brazil) Single injection schedule of BOTOX® in both hands, diluted in 2 ml of sterile serum saline, with a dosage of 50 UI (1 ml) by hand. Injections will be performed at the level of the distal palmar crease, targeting the neurovascular bundles in the 4 web spaces (0.25 ml/injection site) * between 2 to 3 hours before the procedure, application of lidocaine/prilocaine cream under an occlusive dressing (polyurethane film) in each palmar crease of the patients (1/2 tube/hand), according to the recommendations of the manufacturer * inhaled nitrous oxide/oxygen (50% / 50%) may be used, if needed
Placebo group
PLACEBO COMPARATOR* Saline serum * lidocaine/prilocaine cream * Nitrous oxide/oxygen (50%/50%) Intervention Description : * Sterile saline solution Single injection schedule of 2 ml (1 ml by hand) of serum saline, in both hands. Injections will be performed at the level of the distal palmar crease, targeting the neurovascular bundles in the 4 web spaces (0.25 ml/injection site). * between 2 to 3 hours before the procedure, application of lidocaine/prilocaine cream under an occlusive dressing (polyurethane film) in each palmar crease of the patients (1/2 tube/hand), according to the recommendations of the manufacturer of the lidocaine cream. * inhaled nitrous oxide/oxygen (50% / 50%) may be used, if needed
Interventions
Botox solution + Saline serum + lidocaine/prilocaine cream + Nitrous oxide/oxygen (50%/50%)
