Critères de sélection

Critères d'inclusion

Inclusion Criteria:

1. Renal biopsy report supporting diagnosis of primary IgAN or IgA vasculitis-associated nephritis within 10 years prior to the screening visit.
2. UPCR greater than or equal to (\>=) 1 milligram per milligram (mg/mg) or urine protein excretion (UPE) \>=1 gram per day (g/day) by 24-hour urine collection during the screening period.
3. Estimated glomerular filtration rate (eGFR) \>=45 milliliter per minute per 1.73 square meter (mL/min/1.73m\^2) at screening.
4. Receiving stable background therapy for IgAN (angiotensin-converting enzyme inhibitor \[ACE-I\] or angiotensin receptor blocker \[ARB\]) for 12 weeks prior to screening. The ACE-I and ARB dose should represent the maximum tolerated or maximum labeled dose, as determined by the investigator, for a minimum of 3 months and remain stable during the entire duration of the study.

Exclusion Criteria:

1. Kidney biopsy confirming significant renal disease other than IgAN.
2. Secondary IgAN (such as with significant liver disease, inflammatory bowel disease, and seronegative spondyloarthropathies).
3. Evidence of rapidly progressive glomerulonephritis (loss of \>=50 percent (%) of eGFR within 3 months prior to the screening visit).
4. Diagnosis of nephrotic syndrome defined as 24-hour proteinuria greater than (\>) 3.5 g/day, hypoalbuminemia (smaller than \[\<\] 30 g/L) with or without peripheral edema at the screening visit.
5. Diagnosis of acute active extrarenal IgA vasculitis (Henoch-Schönlein purpura) manifested by the involvement of other organs (palpable purpura, abdominal pain, and arthritis) at the screening visit and within 1 year prior to the screening visit.
6. Previous treatment with immunosuppressive agents such as cyclophosphamide, mycophenolate mofetil (MMF), cyclosporine, azathioprine, calcineurin inhibitors within 6 months prior to the screening visit or expected use of any of these agents for the duration of the study.
7. Use of systemic corticosteroids within 4 months from screening visit or expected use for the duration of the study.

Use of B-cell-directed biologic therapies such as blisibimod, belimumab, rituximab, ocrelizumab or have used other biologics (example, anti-tumor necrosis factor \[TNF\], abatacept, anti-interleukin \[IL\]-6) within 6 months prior to the screening visit or expected use of any of these agents for the duration of the study.
8. Participation in another investigational study within 4 weeks or 5 half-lives of study drug, whichever is longer, before the screening visit (the 4-week window is derived from the date of the last study procedure, and/or AE related to the study procedure in the previous study, to the screening visit of the current study) or expected use of an investigational agent from another investigational study during the time of this study.
9. Administration of any vaccine within 28 days before the screening visit or of any live or live-attenuated vaccination planned for the duration of the study.
10. An opportunistic infection smaller than or equal to (\<=) 12 weeks before screening visit or currently receiving treatment for a chronic opportunistic infection, such as tuberculosis (TB), pneumocystis pneumonia, cytomegalovirus, herpes simplex virus, herpes zoster, or atypical mycobacteria. A mild, localized herpes simplex infection within 12 weeks of study dosing is allowed, as long as the lesion has resolved prior to Day 1.
11. A positive T-cell interferon-gamma release assay (TIGRA) (result through QuantiFERON-TB Gold test or T-Spot/Elispot) at the screening visit.
12. A positive test result for hepatitis B surface antigen, or hepatitis B core antibody, or hepatitis C antibody, or HIV antibody/antigen at screening. However, an individual who has a known history of chronic hepatitis C and has been treated and fully cured of the disease, confirmed with a negative hepatitis C virus RNA polymerase chain reaction (PCR) test at screening, is not excluded on the basis of the positive hepatitis C antibody alone.
13. Inadequate organ and bone marrow function at screening visit.
14. Presence of uncontrolled or New York Heart Association (NYHA 1994) Class 3 or 4 congestive heart failure at the screening visit.
15. Uncontrolled diabetes manifested by glycosylated hemoglobin (HbA1c) \>8% at the screening visit.
16. Current malignancy or history of malignancy during the previous 5 years, except adequately treated basal cell or squamous cell carcinomas of the skin or carcinoma in situ/cervical intraepithelial neoplasia of the uterine cervix.

    Description de l'étude

    Résumé de l'étude

    This study will have two parts. The main aims are to:

    * check the side effects from mezagitamab.
    * check for long-term side effects from mezagitamab.

    Before starting the study, participants will be asked to provide a 24-hour urine sample. A few weeks later, if enrolled they will begin receiving a subcutaneous injection (under the skin) of mezagitamab once a week for 8 weeks then once every 2 weeks for 16 weeks. When treatment has ended, there will be a 24-week follow-up period.

    Participants who receive benefit from the treatment may continue in the second part of the study where they will be monitored for up to 96 weeks and possibly retreated for another 24 weeks.

    The drug being tested in this study is called mezagitamab. Mezagitamab is being tested for the first time in this patient population and might help to treat people who have Primary Immunoglobulin (IgA) Nephropathy. This study will evaluate the safety, tolerability, pharmacokinetics, and efficacy of mezagitamab in combination with stable background therapy.

    The study will enroll approximately 16 participants. The study will consist of 2 key components: a main study and a long-term extension (LTE) study, which includes an observation period and a retreatment period. The observation period of the LTE study is a non-interventional study segment and the retreatment period of the LTE study consists of a redosing period in which participants will be administered mezagitamab at the same dose level as in the main study. Only participants who have a positive outcome during the main study will enter LTE study.

    Participants will be enrolled to the following cohort:

    • Mezagitamab

    This multi-center trial will be conducted in the United States, Europe, and Asia Pacific. The overall time to participate in this study is approximately 154 weeks.
