Is this trial a fit for you?
✓Likely a good fit
Adults with biopsy-confirmed IgA nephropathy, C3 glomerulopathy, or IC-MPGN who have active disease, an eGFR ≥30 mL/min/1.73 m2, and are on standard supportive care (ACE inhibitor/ARB when applicable) are the intended candidates.
✕Probably not a fit
Patients with hereditary or acquired complement deficiency, prior complement inhibitor treatment, a kidney transplant or dialysis dependence, active systemic infection, or significant liver test abnormalities are unlikely to benefit or are excluded from participation.

What this trial studies
This Phase 2 interventional trial gives adults with biopsy-confirmed complement-mediated kidney diseases one of two dose levels of ADX-038 and follows them for safety, kidney outcomes, and drug exposure/effects (PK/PD). Eligible participants must have clinical evidence of active disease, an eGFR ≥30 mL/min/1.73 m2, and be on guideline supportive care including ACE inhibitor or ARB when appropriate, while several conditions (prior complement inhibitors, transplant, active infection, abnormal liver tests) exclude enrollment. The protocol compares two dose levels to characterize tolerability, biological target engagement, and preliminary signs of kidney benefit. Study visits take place at ADARx Clinical Sites in South Florida with required vaccinations and routine monitoring for infections and lab abnormalities.
Why it matters
Potential benefit: If successful, ADX-038 could reduce complement-driven kidney inflammation and slow loss of kidney function in affected patients.
How similar studies have gone: Other drugs that target the complement system have shown promising signals in related kidney diseases, but complement-targeting approaches are still being actively studied and are not yet definitive.
