Low dose mycophenolate mofetil versus cyclophosphamide in the induction therapy of lupus nephritis in Nepalese population: a randomized control trial.

ABSTRACT: BACKGROUND:The management of proliferative lupus nephritis (LN) comprises timely and coordinated immunosuppressive therapy. This study aimed to evaluate and compare the effectiveness and safety profile of low dose mycophenolate mofetil (MMF) and cyclophosphamide (CYC) in induction therapy of LN in Nepalese population. METHODS:We conducted a prospective, open-label, randomized trial over a period of one and half years. Forty-nine patients with class III to V lupus nephritis were enrolled, out of which 42 patients (21 in each group) could complete the study. CYC was given intravenously as a monthly pulse and MMF was administered orally in the tablet form in the maximum daily dose of 1.5 g in two divided doses. RESULTS:The mean age of the patients was 25.43?±?10.17 years with female to male ratio of 7.3:1. Mean baseline serum creatinine was 1.58?±?1.38 mg/dL and eGFR was 62.38?±?26.76 ml/min/1.73m2. Mean 24-h urinary protein was 4.35?±?3.71 g per 1.73 m2 body surface area. At 6 months, serum creatinine (mg/dL) decreased from 1.73 to 0.96 in CYC and from 1.24 to 0.91 in the MMF group with improvement in eGFR (ml/min/1.73 m2) from 60.33 to 88.52 in CYC and from 64.42 to 89.09 in MMF group. Twenty-four-hour urinary protein (gm/1.73m2) reduced from 4.47 to 0.94 in CYC and from 4.5 to 0.62 in the MMF group. Primary end point was achieved in higher percentage of patients with MMF than CYC (28.6% vs. 19%) while equal proportion of patients (67% in each group) achieved secondary end point in both groups. Number of non-responders was higher in CYC group than in the MMF group (14.3% vs. 4.8%). There was no difference in the rate of achievement of secondary end point in both CYC and MMF groups (3.16 vs. 3.05 months). The occurrence of adverse events was higher in the CYC than in MMF group (56 vs. 15 events). CONCLUSION:Present study has concluded that MMF, used in relatively lower dose, is equally effective in inducing remission with reduction of proteinuria and improvement of kidney function with lesser adverse events than CYC in the induction therapy of proliferative lupus nephritis. TRIAL REGISTRATION:Retrospectively registered to ClinicalTrials.gov PRS. NCT03200002 (Registered date: June 28, 2017).

Project description:IntroductionBoth mycophenolate mofetil (MMF) and intravenous cyclophosphamide (CYC) have been recommended in the induction therapy of lupus nephritis (LN) for years; nevertheless, their effectiveness and safety in a real-world setting are extremely lacking. Therefore, we decided to conduct this real-world study.MethodsA total of 195 Chinese patients with LN who were initially treated with MMF (n = 98), or intravenous CYC (n = 97) as induction therapy were enrolled. All of the patients were followed up to 12 months. Complete renal remission (CRR) was defined as 24-h urinary protein (24 h-UTP) < 0.5 g, and partial renal remission (PRR) was defined as ≥ 50% reduction in 24 h-UTP to the subnephrotic level, however > 0.5 g, both with a change of serum creatinine (SCr) within 10% from baseline. The proportions of CRR, PRR, and total renal remission (TRR), as well as adverse events, were compared by Chi-square test and Kaplan-Meier analysis (log-rank test). Inverse probability of treatment weighting (IPTW) was used for propensity score matching and multivariable logistic regression analyses were employed.ResultsThe cumulative proportion of TRR in 6 months (79.4 vs. 63.8%, p = 0.026) and CRR in 12 months (72.8 vs. 57.6%, p = 0.049) in MMF group were significantly higher than CYC group, and the above conclusions were further confirmed by IPTW. The proportions of PRR, CRR, and TRR at other time points were equivalent between two groups. Further subgroup analysis in 111 patients with biopsy-proven III-V LN also showed a significantly higher proportion of TRR at 6 months in the MMF group than in the CYC group (78.3 vs. 56.9%, p = 0.026). In the Kaplan-Meier analysis and after IPTW, the MMF group showed better TRR and CRR responses than CYC group in 12 months. Multivariable logistic regression analyses revealed that MMF use was the only predictor of CRR (HR 2.12, 95% CI 1.90-4.09, p = 0.026), while low complement level was also a predictor, albeit risk was reduced (HR 0.38, 95% CI 0.17-0.86, p = 0.019). Moreover, compared to the CYC group, MMF group patients were more likely to have significantly lower SCr (μmol/l) [72.5 (62.5, 86.5) vs. 79.0 (71.1, 97.5), p = 0.001] and daily dose of prednisone (mg/day) (15.7 ± 5.2 vs. 18.6 ± 11.3, p = 0.022) at 6 months; lower 24 h-UTP (g) [0.1 (0.1, 0.3) vs. 0.2 (0.1, 0.9), p = 0.005] and daily dose of prednisone (mg/day) (9.6 ± 3.3 vs. 11.2 ± 5.5, p = 0.023) at 12 months. Infection was the most common adverse event. Pneumonia and gastrointestinal discomfort were more frequently observed in the CYC group.ConclusionsReal-world data are a key component of the evidence supporting the effectiveness of drugs and are of interest to all stakeholders. Our comparative study demonstrated the effectiveness of MMF in LN induction therapy was at least equivalent to intravenous CYC, with superior tolerance.

Project description:Mycophenolate mofetil (MMF) is an immunosuppressant drug being used for induction and maintenance of remission of lupus nephritis in systemic lupus erythematosus. Evidence about its use was sought from full publications and abstracts of randomised trials and cohort studies by using a variety of search strategies. Efficacy and adverse event outcomes were sought. Five randomised trials enrolled patients with World Health Organization (WHO) class III, IV, or V (mostly IV) lupus nephritis, predominantly comparing MMF (1 to 3 g daily) with cyclophosphamide and steroid. Complete response and complete or partial response was significantly more frequent with MMF than with cyclophosphamide, with numbers needed to treat of 8 (95% confidence interval 4.3 to 60) to induce one additional complete or partial response, with wide confidence intervals. Death was reported less frequently with MMF (0.7%, 1 death in 152 patients) than with cyclophosphamide (7.8%, 12 deaths in 154 patients), with a number needed to treat to prevent (NNTp) one death of 14 (8 to 48). Hospital admission was also lower with MMF (1.7% versus 15%; NNTp 7.4 [4.8 to 16]). Serious infections, leucopaenia, amenorrhoea, and hair loss were all significantly less frequent with MMF than with cyclophosphamide, but diarrhoea was significantly more common with MMF. Ten of 18 cohort studies enrolled only patients with lupus nephritis (author-defined or WHO class III to V). Seven of these 10 reported that complete or partial response with MMF (mostly 1 or 2 g daily) with steroid occurred in 121/151 (80%) and that treatment failure or no response occurred in 30/151 (20%). Adverse events were generally similar in cohort studies with and without only patients with lupus nephritis. In all 18 cohorts, gastrointestinal adverse events (diarrhoea, nausea, vomiting) occurred in 30%, infection in 23%, and serious infection in 4.3%. Adverse event discontinuations occurred in 14% and lack of efficacy occurred in 10%. There was a single death with MMF, a mortality rate over the course of 1 year of approximately 0.2%. The results form a basis on which to plan future studies and provide a guide for the use of MMF in lupus nephritis until results of larger studies are available. At least one such study is under way.
