Participants will:
- Receive a single dose of 100 mg rituximab IV
- Have regular follow-up consultations for 6 months following rituximab infusion
- Follow a simultaneous corticosteroid tapering plan

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Rituximab (RTX)Drug
A single ultra-low dose rituximab (100 mg) infusion for patients with immune-related adverse events
| Study group | Role | What they receive |
|---|---|---|
| Rituximab | Experimental | Not described Receives: Drug: Rituximab (RTX) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence and severity of rituximab-related adverse events graded according to CTCAE v. 6.0
Safety of rituximab is evaluated by the Common Terminology Criteria for Adverse Events (CTCAE) v. 6.0 and include the incidence and severity of rituximab-related adverse events until 6 months post treatment.
Measured: Until 6 months post treatment
Secondary outcomes (4)
Immune-related adverse event management response
The immune-related adverse events management response, defined as number of days until symptom control (corresponding to CTCAE grade 0-1 of the immune-related adverse event)
Measured: Until 6 months post treatment
Corticosteroid dependency
Corticosteroid dependency in rituximab treated patients measured as the number of days on corticosteroids following rituximab infusion.
Measured: Until 6 months post treatment
Dose of corticosteroids
Assessment of rituximab efficacy measured as cumulative dose and peak dose of corticosteroids.
Measured: Until 6 months post treatment
Second- or third-line immunosuppressants
Assessment of rituximab efficacy measured as the proportion of patients requiring second- or third-line immunosuppressive therapy after rituximab
Measured: Until 6 months post treatment

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Rituximab (RTX) in people with Immune-Related Adverse Events, run by Inge Marie Svane at 1 site in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Inge Marie Svane, Professor, MD, PhD (004538683868, inge.marie.svane@regionh.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence and severity of rituximab-related adverse events graded according to CTCAE v. 6.0 (time frame: Until 6 months post treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Oct 2026.
