E.3 | Principal inclusion criteria |
1. ≥18 to ≤80 years (at date of signing ICF) 2. Urine protein to creatinine ratio (UPCR) of ≥ 3.0000 g/g OR proteinuria ≥ 3.500 g/24 h from 24-hr urine at screening 3. Active and anti-PLA2R antibody positive MN in need for IST according to investigator judgement and with diagnostic biopsy, archival biopsy acquired within 5 years prior to screening is acceptable 4. Estimated glomerular filtration rate (eGFR) ≥50 ml/min/1.73m² or >30 and <50 ml/min/1.73m², and IFTA (interstitial fibrosis and tub-ular atrophy) score of less than 25% on a renal biopsy obtained within the last 6 months prior to start of screening. If a subject falls into the latter range without availability of an adequate biopsy, a biopsy at screening should be performed for IFTA assessment. 5. Not in spontaneous remission despite proper treatment with ACEIs, ARBs (sufficient dose and treatment duration) as per clinical practice and guidelines. If the PI determines that a subject is intolerant to an ACEI or ARB, the reason must be documented and approval obtained from the Medical Monitor prior to enrolment. 6. Systolic BP ≤ 150 mmHg and diastolic BP ≤ 100 mmHg after a period of 5 minutes of rest as measured at screening 7. Subject vaccinated against Pneumococcus within the last 5 years prior to date of signing ICF (subjects may be vaccinated during screening to meet this criterion; interval to first dose of MOR202 must be at least 14 days (1)). 8. Cohort 1 comprises newly or relapsed subjects: Serum anti-PLA2R antibodies ≥ 50.0 RU/mL determined by Euroimmun ELISA at central laboratory. 9.Cohort 2 comprises therapy refractory subjects: a. subject did not achieve immunological remission after prior IST(s) as documented by the investigator AND b. subject is without promising standard therapeutic options as documented by the investigator(i.e. investigator expects efficacy or safety issues with remaining IST options AND c. serum anti-PLA2R antibodies ≥20RU/mL measured at screening by the Euroimmun ELISA at central laboratory 10. Female of non-childbearing potential fulfilling one of the criteria: a. post-menopausal: after 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) b. surgically sterile: tubal ligation at least 6 weeks before taking trial treatment, hysterectomy, or bilateral oophorectomy c. genetically sterile: e. g. Turner syndrome, uterine agenesis. 11. Sexually active females of reproductive potential should use one of the following contraception options until 3 months after the last dose of MOR202: a. One method of contraception that has a typical use failure rate of <1% (i.e., less than 1 pregnancy expected per 100 women), which would include sterilization surgery for women, sterilization implant for women, sterilization surgery for men, Copper IUD, IUD with progestin, or implantable rod b. A hormonal method of contraception (i.e., shot/injection, oral contraceptive, contraceptive patch, vaginal contraceptive ring, having typical use failure rate ≤ 9%) plus a barrier method (i.e., diaphragm with spermicide, sponge with spermicide, cervical cap with spermicide, male condom, female condom, spermicide alone). Note: France will only enroll patients in Cohort 2. |

Hypogammaglobulinemia: Serum immunoglobulins ≤4.0 g/L 6. B-cells < 5 x 106/L 7. Secondary cause of MN (e.g. SLE, medications, malignancies) as determined by the investigator 8. Concomitant renal disease other than MN (e.g., diabetic renal disease, lupus nephritis, IgA nephropathy) 9. Diabetes mellitus type 1 10. Diabetes mellitus type 2: Subjects with type 2 diabetes mellitus may only enter the clinical trial if a kidney biopsy performed within 6 months prior to screening shows membranous nephropathy without histological signs of diabetic nephropathy and their disease is controlled, such as: o Hba1c <8.0 % or 64 mmol/mol, o No diabetic retinopathy known o No peripheral neuropathy known 11. Previous treatment with an anti-CD38 antibody 12. Subject received treatment with: a.Mycophenolate mofetil (MMF) or high dose corticosteroids (> 20 mg prednisone/day), within 30 days prior to screening OR b.Alkylating agents (e.g. cyclophosphamide [CYC]) or CNIs (e.g. tacrolimus, cyclosporine A [CSA]) within 90 days OR c.Biologic drugs including RTX within 180 days d.Any other oral/parenteral IST within 180 days. 13. Significant uncontrolled cardiovascular disease or cardiac insufficiency (New York Heart Association [NYHA] class IV) as judged by the investigator 14. Clinically relevant findings on a 12 lead ECG as determined by the investigator at screening 15. History of significant cerebrovascular disease or sensory or motor neuropathy of tox-icity ≥ grade 3 16. Total bilirubin, aspartate aminotransferase and alanine aminotransferase >1.5 x ULN, alkaline phosphatase >2.0 x ULN 17. Treatment within five terminal half-lives (if known) or within the last 30 days prior to baseline (whatever is longer) with investigational drugs. 18. Known or suspected hypersensitivity to MOR202 and its excipients (L-histidine, su-crose, polysorbate 20) 19. Serologic or virologic markers positive for HIV, hepatitis C (subjects with positive anti hepatitis C virus [anti-HCV] antibody but negative HCV RNA polymerase chain reaction [PCR] may enroll) or active or latent hepatitis B (subjects with positive hepatitis B surface antigen [HBsAg] are excluded, subjects with isolated positive hepatitis B core antibody [anti-HBc] but non-detectable hepatitis B virus (HBV) DNA by PCR may be enrolled). 20. For any other pre-existing symptoms and impairments of health classified or any re-sidual toxicity from prior therapy ≥ grade 3 (NCICTCAE, see 3.2): these subjects may be included upon confirmation by the medical department of the sponsor 21. Pregnancy or breast feeding 22.Any active infection (viral, fungal, bacterial) requiring systemic therapy. 23.Any malignancy within 5 years prior to date of screening, with the exception of adequately treated in situ carcinoma of the cervix, uteri, basal or squamous cell carcinoma or non-melanomatous skin cancer. |
