Systemic Sclerosis
Conditions
Brief summary
This study evaluates the effect of intestinal microbiota therapy on gastro-intestinal symptoms in patients with systemic sclerosis (SSc). This is a mulicenter randomized controlled trial conducted at university hospitals in Oslo, Tromsø, Bergen and Trondheim in Norway. In part A1, half of the patients will receive active substance (intestinal microbiota cultured in the lab - ACHIM) in the small intestine twice by gastroduodenoscopy, the other half will receive placebo. The primary outcome will be measured on week 12 by patient reported outcome measures. In part A2, all participants receive ACHIM at week 12, with an 8 week follow-up for all. A step-wise follow-up will be done in part B up to 16 weeks after week 20 until the last participant finish week 20 visit, which is defined as end of study.The blind from the first intervention will not be opened before end of study.
Interventions
Culture of intesinal microbiota originally derived from a healthy subject are administered to a person with presumed dysbiotic intestinal symptoms with an objective to treat these symptoms.

Masking description
Masking will apply for the whole duration of study until end of study defined as week 20 visit for the last participant.
Intervention model description
The 20-week study period consists of a 12-week induction phase (Part A1), with randomized, double-blind parallel group interventions by endoscopic infusions at weeks 0 and 2, and an 8-week maintenance phase (Part A2) where all participants receive one single open label endoscopic infusion on week 12. Additionally, all participants who complete the 20-week study period are followed for a maximum 16 weeks monitoring period (Part B) to obtain longer-term data on safety and durability of intervention effects.
