What the trial is, and whether it could suit you
The goal of this pilot study is to assess the feasibility of a larger study on the efficacy of mycophenolate mofetil in people diagnosed with systemic sclerosis with mild lung involvement. Participants will be recruited over 12 months at 3 academic centers and assigned randomly to receive either mycophenolate mofetil or placebo, a look-alike substance that contains no active drug, for 96 weeks.

5. Persistent anemia (hemoglobin \<100 g/L)
6. Baseline liver enzymes (alanine transaminase (ALT) or aspartate transaminase (AST)) or bilirubin \>1.5 times the upper limit of normal, other than due to Gilbert's disease
