11 The multicenter, randomized FAST trial explored the effect of low-dose prednisone and intravenous (iv) CYC for 6 months, followed by maintenance AZA in SSc-ILD. Compared with placebo, predicted FVC in the treatment group improved by 4.2%, but only with a trend towards significance ( p = 0.08) after 12 months. 17 Due to potential bladder toxicity, continuing CYC long-term is challenging.
