简要总结
This study is an exploratory, randomized, double-blind, multicenter, placebo-controlled study with repeated doses of AP1189. The study population will consist of patients with idiopathic membranous nephropathy (iMN) and severe proteinuria who are on ACE inhibitor or angiotensin II receptor blocker treatment.
详细描述
This study is an exploratory, randomized, double-blind, multicenter, placebo-controlled study with repeated doses of AP1189. The study population will consist of patients with idiopathic membranous nephropathy (iMN) and severe proteinuria who are on ACE inhibitor or angiotensin II receptor blocker treatment. Following a successful screening, subjects who fulfill the enrollment criteria will be randomized in a 2:1 ratio in group A and B: * Group A (12 subjects): AP1189 dose 100 mg, once daily for 12 weeks (28 days) as an add-on to any ongoing treatment, including ACE inhibitors/ angiotensin II receptor blocker * Group B (6 subjects): placebo for 12 weeks (28 days) as an add-on to any ongoing treatment including ACE inhibitors/ angiotensin II receptor blocker.

入排标准
入选标准
- •Written informed consent has been obtained prior to initiating any study-specific procedures
- •Male and female subjects, 18 to 85 years of age diagnosed with iMN within 6 months prior to inclusion
- •Diagnosed as anti-PLA2-Receptor positive by local laboratory within 6 months prior to 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 a P-albumin below the lower normal limit
- •eGFR \> 30 ml/min/1.73m2
- •Treated with ACE- inhibitors or angiotensin II receptor blocker for a minimum of 1 months 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 effect
- •Only Denmark and Norway:
- •Females of child-bearing potential using reliable means of contraception or are post-menopausal
- •Females of childbearing potential with negative pregnancy test at screening and baseline
- •Only Sweden:
排除标准
- •Participation in any other study involving investigational drug(s) during the study and within 4 weeks prior to study entry
- •Clinicial findings that in the opinion of the investigator would suggest condition(s) other than iMN as a major cause of severe proteinuria
- •Major surgery within 8 weeks prior to screening or planned surgery within 1 month following randomization
- •Blood pressure with systolic pressure above 160 mmHg and/or diastolic pressure above 100 mmHg despite antihypertensive treatment will in all cases be considered "uncontrolled"

- •Treated with rituximab within 12 months of screening
- •Evidence of active malignant disease
- •Uncontrolled disease states, such as asthma, psoriasis, or inflammatory bowel disease where flares are commonly treated with oral or parenteral corticosteroids
- •Evidence of serious uncontrolled concomitant cardiovascular, nervous system, pulmonary, renal, hepatic, endocrine or gastrointestinal disease
- •Pregnant women or nursing mothers
