Authorised Therapeutic exploratory (Phase II) Idiopathic membranous nephropathy and severe proteinuria

An exploratory, randomized, double-blind, multicenter, placebo-controlled study to assess the safety, tolerability, pharmacokinetics, and efficacy of AP1189 daily doses versus placebo administered for 12 weeks as an addon to patients, in ACE inhibitor or angiotensin II receptor blocker treatment, with idiopathic membranous nephropathy and severe proteinuria

EU CTIS ID: 2024-518384-36-00

What this study is testing

To compare the safety of AP1189 against placebo by evaluating adverse events (AEs), serious adverse events (SAEs), vital signs, electrocardiograms and laboratory abnormalities. The result of 12 weeks of treatment on 24 hours urinary protein excretion as expressed as changes in urine excretion from baseline to the end of the twelve weeks treatment period (baseline is defined as 24 h urinary protein excretion determined prior to dosing with AP1189 or placebo).

Who can take part

You may be able to join if

  • Written informed consent has been obtained prior to initiating any study-specific procedures
  • Male and female subjects, 18 to 85 years of age with iMN and severe proteinuria
  • Diagnosed as anti-PLA2-Receptor positive by local laboratory within 6 months prior to inclusion and/or having a renal biopsy consistent with iMN within 24 months of inclusion
  • Severe proteinuria defined by a U-protein/creatinine ratio >3.0 g/g and/or U-albumin/creatinine ratio >2.0 g/g and P-albumin below the lower normal limit
  • eGFR > 30 ml/min/1.73m2
  • Treatment with ACE- inhibitors or angiotensin II receptor blocker for a minimum of 1 month with a stable systemic arterial blood pressure OR treatment with ACE inhibitors and/or angiotensin receptor blocker was excluded or discontinued due to hypotension, intolerance or other side effects

You likely can't join if

  • Participation in any other study involving investigational drug(s) during the study and within 4 weeks prior to study entry
  • Pregnant women or nursing (breastfeeding) mothers
  • History of alcohol, drug, or chemical abuse within the 6 months prior to screening
  • Any condition that in the view of the investigator would suggest that the patient is unable to comply with study protocol and procedures (e.g., psychiatric disorders, dementia)
  • ONLY SWEDEN: Females of child-bearing potential
  • Clinical findings that in the opinion of the investigator would suggest condition(s) other than iMN as a major cause of severe proteinuria
