COVID-19 studies are our top priority.

For new and updated trial submissions, we are processing trials as quickly as possible and appreciate your patience. We recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
Participants are eligible to be included in the study only if all of the following criteria
apply:

1. Participant is a male or female = 18 years of age at the time of signing the informed
consent.

2. Participant must have biopsy-confirmed IgAN.

3. Participant has medical records showing they have been on stable and maximally
tolerated doses of either ACEI or ARB, as per local SOC and applicable guidelines, for
at least 3 months preceding screening. Participants should optimally be on at least
50% of the maximum recommended dose of these agents; however, if a participant is on
their maximally tolerated dose (and this is < 50% of the maximum recommended dose) and
has been on this dose for at least 3 months, they may be enrolled. Participants who
are unable to tolerate ACEI/ARB therapy may be eligible for participation in the study
if their overall management of IgAN, including BP control, is as per local SOC and
applicable guidelines.

4. Participants must have screening uPCR = 0.75 g/g measured from a 24-hour urine or
24-hour urine protein = 1.0 g/d, as measured from 24-hour urine collection. The
proteinuria should be assessed when the participant is considered to be in a steady
state with no recent heavy exercise, fever, or other potential issues that could
impact the result.

5. Participants must have eGFR = 45 mL/min/1.73 m².

6. Participant's serum Ig values must meet specified criteria

7. Female participants of childbearing potential must have a negative serum pregnancy
test prior to the first dose.

8. Participant is willing to adhere to contraceptive requirements.

9. Participant or a legally authorized representative is able and is willing to give
voluntary written informed consent
Minimum age
18 Years
Maximum age
No limit
Gender
Both males and females
Can healthy volunteers participate?

Key exclusion criteria
Participants are excluded from the study if they meet any of the following criteria:

1. Participant has secondary forms of IgAN as defined by the treating physician.

2. Participant has co-existing CKD, other than IgAN.

3. Participant has evidence of additional pathological findings in the kidney biopsy (eg,
diabetic kidney disease, membranous nephropathy, or lupus nephritis). However,
hypertensive vascular changes are acceptable.

4. Participant has kidney biopsy MEST or MEST-C score as defined in the protocol.

5. Participant has nephrotic syndrome.

6. Participant has received a solid organ transplant, including kidney.

7. Participant has received bone marrow or hematologic stem cell transplantation.

8. Participant is currently receiving systemic immunosuppression (excluding topical,
ophthalmic, per rectum, or inhaled corticosteroids).

9. Participant has received treatment with systemic corticosteroid therapy within 16
weeks of initial screening.

10. Participant has received treatment with a systemic immunosuppressive agents within 16
weeks of initial screening.

11. Participant has any chronic infectious disease.

12. Participant has acute infectious disease at the time of screening.

13. Participant has Type 1 diabetes.

14. Participant has uncontrolled Type 2 diabetes, as evidenced by a screening hemoglobin
A1c value > 8%.

15. Participant has uncontrolled BP (> 140 mm Hg systolic or > 90 mm Hg diastolic)

16. Participant has a history of chronic autoimmune neurodegenerative disorder such as
multiple sclerosis.

17. Participant has a known allergy or intolerance to any component of the study
intervention.

18. Participant is breastfeeding.

19. Participant has poorly compensated or controlled ischemic heart disease or
cardiomyopathy, as judged by the Investigator.

20. Participant has chronic obstructive pulmonary disease (COPD) or asthma that has
required systemic steroid therapy during the prior year.

21. Participant has known cirrhosis or liver dysfunction, defined as presence of
coagulopathy, platelet count < 100,000/µL or alanine aminotransferase > 3× upper limit
of normal.

22. Participant has active malignancy or is receiving chemotherapy for malignancy, except
for nonmelanoma skin cancers and cervical carcinoma in situ. Participants with prior
malignancy who have been documented to be cancer-free for = 5 years may be enrolled.

23. Participant is planning or scheduled to undergo a tonsillectomy. Prior tonsillectomy
is acceptable (if greater than 6 months prior to screening).

24. Participant enrolled in another investigational drug or device study within 3 months
prior to initial screening.

25. Participant with a pre-existing illness other than those listed above that, in the
opinion of the Investigator, would place the participant at increased risk through
participation in this study.

26. Participant is unable to comply with study protocol procedures and/or study visit
schedules.

27. Participant with known or suspected alcohol or drug abuse that would compromise their
safety or study participation of the participant, in the opinion of the Investigator.
