Abstract
- To assess prevention of bone mineral density (BMD) loss and durability of the response during treatment with prasterone in women with systemic lupus erythematosus (SLE) receiving chronic glucocorticoids. METHODS: 155 patients with SLE received 200 mg/day prasterone or placebo for 6 months in a double-blind phase. Subsequently, 114 patients were re-randomized to receive 200 or 100 mg/day prasterone for 12 months in an open-label phase. Primary efficacy endpoints were changes in BMD at the lumbar spine (L-spine) from baseline to Month 6 and maintenance of BMD from Month 6 to 18 for patients who received prasterone during the double-blind phase. RESULTS: In the double-blind phase, there was a trend for a small gain in BMD at the L-spine for patients who received 200 mg/day prasterone for 6 months versus a loss in the placebo group (mean ± SD, 0.003 ± 0.035 vs -0.005 ± 0.053 g/cm2, respectively; p = 0.293 between groups). In the open-label phase, there was dose-dependent increase in BMD at the L-spine at Month 18 between patients who received 200 versus 100 mg/day prasterone (p = 0.021). For patients who received 200 mg/day prasterone for 18 months, the L-spine BMD gain was 1.083 ± 0.512% (p = 0.042). There was no overall change in BMD at the total hip over 18 months with 200 mg/day prasterone treatment. The safety profile reflected the weak androgenic properties of prasterone. CONCLUSION: This study suggests prasterone 200 mg/day may offer mild protection against bone loss in women with SLE receiving glucocorticoids.
