Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with primary IgA nephropathy, 24-hour protein ≥1 g/day or UPCR ≥0.7 g/g, eGFR ≥30 mL/min/1.73 m2, and meeting the protocol's weight, BMI, and contraception requirements are the ideal candidates.

Probably not a fit

Patients with secondary causes of IgAN, a history of organ transplantation or splenectomy, recent or active malignancy, eGFR below 30 mL/min/1.73 m2, or proteinuria below the entry thresholds are unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, double-blind, placebo-controlled Phase II trial will enroll about 84 adults with primary IgA nephropathy who meet proteinuria and eGFR entry criteria. After a screening and run-in period, participants will receive SHR-2173 or placebo injections during a 48-week double-blind treatment period followed by a 12-week safety follow-up. The study will compare changes in proteinuria and kidney function while monitoring safety and tolerability. Background standard-of-care treatments and protocol-specified contraception measures are maintained throughout the trial.

Why it matters

Potential benefit: If SHR-2173 is effective, it could lower proteinuria and slow decline in kidney function, reducing the long-term risk of kidney failure for people with IgAN.

How similar studies have gone: Some other targeted therapies for IgAN have shown promising results in early trials, but SHR-2173 itself is a newer investigational agent without large Phase III data published yet.
