Background:

The 36-month maintenance phase of the ALMS study (NCT00377637) compared the efficacy and safety of mycophenolate mofetil (MMF) with azathioprine (AZA) in patients with lupus nephritis (LN) classes III, IV and V achieving a clinical response in the induction phase with corticosteroids (CS) and either MMF or cyclophosphamide (IVC).

Methods:

Patients were re-randomized 1:1 to a double-blind comparison of either placebo plus either oral MMF (2 g/day) or oral AZA (2 mg/kg/day). Patients were permitted to receive corticosteroids (maximum dose: 10 mg/day prednisone or equivalent). The primary efficacy outcome measure was time to treatment failure (death, end-stage renal disease, sustained doubling of serum creatinine, and/or renal flare [proteinuric or nephritic]). Patients who withdrew before reaching the primary endpoint were censored at the time of withdrawal. Although this was primarily an LN population, substantial extra-renal assessments were performed. Extra-renal secondary parameters included time to major extra-renal flare (British Isles Lupus Assessment Group [BILAG] score category A in one extra-renal system or three systems with concurrent category B scores) and the characterization of extra-renal activity. Immunology secondary parameters (levels of complement proteins C3 and C4, and titers of antibodies to double-stranded DNA [anti-dsDNA]) and adverse events (AEs) were also assessed.

Results:

Of 227 patients randomized (intent-to-treat population), 127 completed the full 3 years (MMF, 73/116 [62.9%]; AZA, 54/111 [48.6%]): MMF was superior to AZA in the primary endpoint (p=0.003). Extra-renal disease characteristics and immunology parameters were similar across groups at baseline. There were very few occurrences of major extra-renal flare in either group during the study (8 [6.9%] for MMF, 7 [6.3%] for AZA), and time to major extra-renal flare did not differ between groups (p=0.936). However, there were differences in the characteristics of extra-renal activity. The most common manifestation of major extra-renal flare in the MMF group was mucocutaneous and in the AZA group was hematological. In the MMF group, 75 subjects (65.2%) experienced lupus-related AEs compared with 79 (71.2%) in the AZA group, with musculoskeletal events being the most common in both groups (MMF, 39/115 [33.9%]; AZA, 37/111 [33.3%]). At the end of the study, in patients who had completed 3 years, mean C3 and C4 levels were lower in the AZA group and mean anti-dsDNA titers were lower in the MMF group; differences were not statistically significant.

Conclusions:

In this population of LN patients who had responded to induction therapy, there were low levels of extra-renal activity in the maintenance phase in both MMF and AZA groups.
