What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Change of Proteinuria as Measured by Spot Urine Protein/Creatinine Ratio (sPCR) at Week 24

    Mean change from Baseline (Visit 2) of proteinuria as measured by the spot Protein-Creatinine Ratio (sPCR) at 24 weeks (Visit 9) for the ITT Population

    Measured: Baseline to 24 weeks

Secondary outcomes (14)
  1. Mean Change From Pre-treatment to Post-treatment in Mesangial Hypercellularity (M) on Renal Biopsies.

    Mean change from pre-treatment to post-treatment in mesangial hypercellularity on renal biopsies. Using the Oxford Classification of IgA Nepthropathy (IgAN), biopsy specimens with a minimum of 8 glomeruli, mesangial hypercellularity (M), endocapillary hypercellularity (E), segmental sclerosis (S), and interstitial fibrosis/tubular atrophy (T) lesions are scored for assessing histologic findings in IgAN.

    M = the mean score based on Oxford Classification system score is based on total count of mesangial cells for all glomeruli (count of <4=0 score, 4 to 5=1, 6 to 7=2, ≥8=3). A decrease in score equates to improvement from IgAN disease.

    Measured: Baseline to Week 24

  2. Percentage of Subjects With ≥50% Reduction in sPCR From Baseline (Visit 2) at Week 24 (Visit 9).

    Percentage of subjects with ≥50% reduction in sPCR from Baseline (Visit 2) at Week 24 (Visit 9)

    Measured: Baseline to Week 24

  3. Percentage of Subjects With ≥ 30% Reduction in Proteinuria From Baseline (Visit 2) at 24 Weeks (Visit 9).

    Percentage of subjects with ≥ 30% reduction in proteinuria from Baseline (Visit 2) at 24 weeks (Visit 9).

    Measured: Baseline to Week 24

  4. Mean Change From Pre-treatment to Post-treatment in Percentage of Glomeruli With Endocapillary Hypercellularity (E) on Renal Biopsies.

    Mean change from pre-treatment to post-treatment in mesangial hypercellularity on renal biopsies. Using the Oxford Classification of IgA Nepthropathy (IgAN), biopsy specimens with a minimum of 8 glomeruli, mesangial hypercellularity (M), endocapillary hypercellularity (E), segmental sclerosis (S), and interstitial fibrosis/tubular atrophy (T) lesions are scored for assessing histologic findings in IgAN.

    E = Percentage of glomeruli eypercellularity due to increased number of cells within glomerular capillary lumina causing narrowing of the lumina. A decrease in score equates to improvement from IgAN disease.

    Measured: Baseline to Week 24

  5. Mean Change From Pre-treatment to Post-treatment in Percentage of Glomeruli With Segmental Sclerosis/Adhesion (S) on Renal Biopsies.

    Mean change from pre-treatment to post-treatment in mesangial hypercellularity on renal biopsies. Using the Oxford Classification of IgA Nepthropathy (IgAN), biopsy specimens with a minimum of 8 glomeruli, mesangial hypercellularity (M), endocapillary hypercellularity (E), segmental sclerosis (S), and interstitial fibrosis/tubular atrophy (T) lesions are scored for assessing histologic findings in IgAN.

    S = Percentage of any amount of the tuft involved in sclerosis, but not involving the whole tuft or the presence of an adhesion in each glomeruli. A decrease in score equates to improvement from IgAN disease.

    Measured: Baseline to Week 24

  6. Mean Change From Pre-treatment to Post-treatment in Percentage of Glomeruli With Global Glomerulosclerosis Score on Renal Biopsies.

    Mean change from pre-treatment to post-treatment in mesangial hypercellularity on renal biopsies.

    Percentage of any amount of the tuft involved in sclerosis, but not involving the whole tuft or the presence of an adhesion in each glomeruli. A decrease in score equates to improvement from IgAN disease.

    Measured: Baseline to Week 24

  7. Mean Change From Pre-treatment to Post-treatment in Percentage of Glomeruli With Tubulointerstitial Scarring (T) on Renal Biopsies.

    Mean change from pre-treatment to post-treatment in mesangial hypercellularity on renal biopsies. Using the Oxford Classification of IgA Nepthropathy (IgAN), biopsy specimens with a minimum of 8 glomeruli, mesangial hypercellularity (M), endocapillary hypercellularity (E), segmental sclerosis (S), and interstitial fibrosis/tubular atrophy (T) lesions are scored for assessing histologic findings in IgAN.

    T= Percentage of cortical area involved by the tubular atrophy or interstitial fibrosis, whichever is greater. A decrease in score equates to improvement from IgAN disease.

    Measured: Baseline to Week 24

  8. Mean Change From Pre-treatment to Post-treatment in Percentage of Glomeruli With Cellular/Fibrocellular Crescent Score on Renal Biopsies.

    Mean change from pre-treatment to post-treatment in cellular/fibrocellular crescent score on renal biopsies. Biopsy specimens with a minimum of 8 glomeruli, mesangial hypercellularity (M), segmental sclerosis (S), and interstitial fibrosis/tubular atrophy (T) lesions are scored using the Oxford Classification of IgA nepthropathy (IgAN) system for assessing histologic findings in IgAN.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Fostamatinib 150 mg and Fostamatinib 100 mg in people with IGA Nephropathy, run by Rigel Pharmaceuticals at 20 sites in 6 countries.

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 4 inclusion and 2 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: finished, as of the sponsor's last update on 27 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in United Kingdom, United States, Germany, Austria, Hong Kong and 1 more country. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Jun 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Change of Proteinuria as Measured by Spot Urine Protein/Creatinine Ratio (sPCR) at Week 24 (time frame: Baseline to 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02112838, which also lists 3 linked publications.

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 27 Jun 2019.
