Study summary

This study is an open-label, single-arm, exploratory study designed to evaluate the efficacy and safety of Obinutuzumab beta combined with a rapid-tapering glucocorticoid regimen in patients with new-onset ANCA-associated glomerulonephritis (AAGN).

Read the detailed description

This study is an open-label, single-arm, exploratory study designed to evaluate the efficacy and safety of Obinutuzumab beta combined with a rapid-tapering glucocorticoid regimen in patients with new-onset ANCA-associated glomerulonephritis (AAGN). The primary objective is to assess the complete remission rate at Week 24.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • New diagnosis of ANCA-associated vasculitis (Granulomatosis with polyangiitis [GPA] or Microscopic polyangiitis [MPA]) according to the Chapel Hill Consensus Conference definitions.
  • Positive for PR3-ANCA or MPO-ANCA.
  • Active renal involvement indicated by recent renal (pauci-immune necrotizing and/or crescentic glomerulonephritis) OR active urine sediment characterized by glomerular hematuria and proteinuria.
  • Provided signed .

Exclusion criteria

Exclusion Criteria:

  • Prior treatment with targeted B-cell therapies (e.g., Rituximab) or standard cyclophosphamide, azathioprine, or mycophenolate mofetil for AAV.
  • Current requirement for dialysis, or history of dialysis.
  • Presence of life-threatening acute vasculitis manifestations other than renal involvement (e.g., diffuse alveolar hemorrhage, respiratory failure, bowel perforation, cerebral vasculitis).
  • History of within the past 5 years.
  • Coexisting multisystem diseases (e.g., systemic lupus erythematosus, anti-GBM disease).
  • Active severe infections, active tuberculosis, or chronic viral infections ( with positive HBsAg or HBV-DNA, active , ).
  • Pregnant or lactating women.
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorized to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Study arms

  • Experimental
    Obinutuzumab beta + Glucocorticoid

    Participants receive Obinutuzumab beta intravenous infusion during induction phase, combined with oral glucocorticoids following a prespecified rapid tapering schedule aiming for complete discontinuation by Week 24.

    Drug: Obinutuzumab beta · Drug: Glucocorticoids

Interventions

  • Intravenous infusion of Obinutuzumab beta administered during the induction phase.

    Also known as: MIL62

  • Oral glucocorticoid induction starting alongside Obinutuzumab beta, following a prespecified rapid tapering schedule aimed at complete discontinuation by Week 24.

What researchers measure

Primary outcomes

    Dynamic change of eGFR from baseline.

    Time frame: Up to Month 12

  3. Change in proteinuria

    Dynamic change of 24-hour urine protein or Urine Protein-to-Creatinine Ratio (UPCR) from baseline.

    Time frame: Up to Month 12

    Proportion of participants achieving a BVAS of 0.

    Time frame: Up to Month 12

  6. Proportion of participants achieving peripheral B-cell depletion

    Pharmacodynamic assessment of peripheral B-cell count changes from baseline.

    Time frame: Up to Month 12

  7. Change in ANCA serological status and titer levels

    Proportion of participants achieving ANCA negativity and changes in ANCA titers from baseline.

    Time frame: Up to Month 12

  8. Incidence of Treatment-Emergent Adverse Events (TEAEs)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 15, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
