Sequential Therapy With Tacrolimus and Rituximab in Primary Membranous Nephropathy (STARMEN)
European Multicenter and Open-Label Controlled Randomized Trial to Evaluate the Efficacy of Sequential Treatment With Tacrolimus-Rituximab Versus Steroids Plus Cyclophosphamide in Patients With Primary Membranous Nephropathy (The STARMEN Study)
In this study, investigators will evaluated the long-term efficacy and safety (two years) of Tacrolimus-Rituximab (RTX) therapy compared to Methylprednisolone-Cyclophosphamide (CYC) therapy in patients with primary Membranous Nephropathy (MN).
PRINCIPAL OBJECTIVE To evaluate whether sequential therapy with tacrolimus leads to a greater increase in the proportion of primary MN patients with Complete or Partial Remission when compared with patients receiving standard treatment. It will be assessed 24 months after the beginning of treatment.
Phase of the trial: and design: Phase III study, open label, randomized, and active controlled trial.
This study will have 3 stages: screening and recruitment of patients for 18 months, treatment period for six months in corticosteroids plus CYC group and 9 months in Tacrolimus-RTX group, and finally post-treatment follow-up period until to complete 24 months of follow-up since initial treatment.
This study will compare the standard therapy for primary MN patients with nephrotic range proteinuria (active control of steroids plus CYC) with a novel sequential therapy of tacrolimus and RTX, an approach of potential high efficacy, low toxicity and more acceptable safety profile.

PRIMARY AND SECONDARY ENDPOINTS/OUTCOME MEASURES
Primary end-point:
The proportion of patients reaching CR defined as a reduction of proteinuria since baseline level to a value equal or lower than 0.5 g/24 h proteinuria plus stable renal function (eGFR ≥ 45 ml/min/1.73m2) or PR defined as a reduction of proteinuria since baseline level to a value less than 3.5 g/24 h and 50% lower than baseline proteinuria plus stable renal function (eGFR ≥ 45ml/min/1.73m2) at 24 months of study treatment.
Secondary end-points
- The proportion of patients with Limited response (LR) defined as a reduction of proteinuria since baseline level > 50% but to a value > 3.5g/24 h. at 12, 18 and 24 months of study treatment..
- The number of patients with an increase ≥ 50% of serum creatinine (SCr) from baseline at 12, 18 and 24 months (end of the follow-up).
- The time of renal survival (status free of increase ≥ 50% of baseline SCr) in both arms overall after the study.
- The proportion of patients with preserved renal function (estimated GFR ≥ 60 ml/min) in both treatment arms after the treatment period.
- The proportion of patients with relapse (defines as the reappearance of proteinuria > 3.5 gr/24h and at least 50% increase over the lowest baseline value in at least three consecutive visits in those patients who previously presented a PR or CR) and the time to relapse after the treatment period.
- Serum levels of anti-phospholipase A2 receptor antibodies (anti-PLA2R), before of treatment and at 3, 6, 9, 12, 18 and 24 months of study, in both treatment arms.
- The proportion of patient with drug-related adverse events and serious adverse events.
STUDY POPULATION

Genders Eligible for Study
Description
Inclusion Criteria:
- Patients are willing and able to read and correctly understand the patient's information sheet and give their consent for participation in the study (by correctly signing and dating the informed consent form document, which has been previously approved by an Ethics Committee/ International Review Board), before initiating any protocol specific selection procedure.
- Patients are able to understand study procedures and to comply with them for the entire length of the study.
- Age older than 18 years.
- Biopsy-proven primary MN. Patients with nephrotic syndrome relapse after remission (either spontaneous or induced by immunosuppression) can be included without a new renal biopsy, provided that they meet all the other inclusion/exclusion criteria.
- Estimated GFR ≥ 45 ml/min/1.73m2 in one measurement performed within the screening period (in the 30 days after informed consent signature).
- Nephrotic-range proteinuria (>4 g/day and not decreasing >50% in the last 6 months) accompanied by hypoalbuminemia ≤ 3, 5 g/dL during the screening period OR patients showing severe or disabling symptoms related to the nephrotic syndrome or severe hypoalbuminemia (<2 g/dL), that can be included before the completion of this 6-month observation period, at the investigator's discretion, independently of proteinuria values.
- Treatment with an ACEI or ARB for at least 2 months before screening (unless intolerance to ACEI/ARB, contraindications to their use or a low blood pressure that could induce side effects at the investigator's discretion) with a controlled blood pressure for at least the last three months (Mean SBP/DBP ≤ 150/90 mmHg in the last three months).
- Negative urine pregnancy test for potentially fertile female.
Exclusion Criteria:
- Diagnosis of secondary causes of membranous nephropathy: malignancy (cancer), systemic infections (which include B and C hepatitis), systemic autoimmune diseases (e.g. Systemic Lupus Erythematosus; SLE) or any other acute or chronic inflammatory disease.
- HIV infection.
- Moderate or severe liver disease (AST and ALT > 2.5x upper range limit and total bilirubin > 1.5 x upper range limit).
- Patients are taking part in any other study with an investigational study and/or are receiving or have received treatment with another investigational drug or intervention (within the first month prior to the signature of the informed consent).
- Suspected or known hypersensitivity, allergy and/or immunogenic reaction history to either rituximab, cyclosporine, tacrolimus, corticosteroids, CYC or any of their ingredients (which include excipients) and of any other drug from the same pharmacotherapeutic group (i.e. calcineurin inhibitors, specific monoclonal antibodies or alkylating agents).
- Previous treatment with corticosteroids in the three months period before screening, or previous treatment with other immunosuppressive agent in the six month period before screening.
- Previous treatment with rituximab or any other biological agent in the two years period before screening.
- Patients who were non-responders to previous immunosuppressants.
- Women with a positive pregnancy test at screening or in lactation period or planning to become pregnant within the next 24 months. Women not willing to use contraceptive methods during the complete study period.
- Inability or unwillingness of individual or legal guardian/representative to give written informed consent.
- Any other medical unstable, uncontrolled, or severe condition or any other relevant laboratory test finding which, at the investigator's own discretion, could possibly increase the associated risk of the patient's participation in the study.
- Current drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements.
