In the last NephJC, we discussed interim results📊from the PROTECT trial on efficacy & safety of Sparsentan in IgAN.

New light✨on the horizon for IgAN yet?

What did I miss?

3 decades of fateful trials of ERAs in PAH, HTN, DKD, FSGS & IgAN (AFFINITY,ALIGN) set the stage for

270 weeks (114+156 weeks open label with SGLT2i!)

➡️Carefully selected population for nil significant cardio/cerebro-vascular or hepatic disease
➡️On MLD/50% MLD of RAASi
➡️1:1 randomisation
➡️Stratification as per eGFR & proteinuria
➡️MMRM statistics

After 36 weeks of Sparsentan👇
✅41% relative reduction in UPCR
✅Lesser number reached 40% reduction of eGFR, kidney failure or all-cause mortality📊

⏫Freq adverse effects in both groups! (88% vs 78%)

🟰 Similar body weight changes/use of diuretics/BP

A figure paints 1000 words

🔣Geometric least square mean ratio between groups was 0.59 (CI 0.51-0.69)

🛡️Maximal slope of reduction of proteinuria achieved at week 4, continued to accrue up to week 36

Additionally, proteinuria reduction was similar across all sub-groups!

Give me something clever to say

Burning questions defying IgAN trials
🔥A different disease in different ethnicities,fiery variants in some?
🔥Different natural history in primary vs secondary?
🔥Native vs post-transplant?
🔥In children?
🔥With vasculitis?

Chat consensus?

Very adequately put by @hswapnil
We need more data & accelerated approvals using surrogate end-points may not be a bad thing at all.

& Ahem, after rigorous trials & rounds of approval, there's the formidable next challenge- COST!💰

Quote (Question) of the fortnight (decade really)

Will we ever have an answer? Unless we look systematically at the natural course/course on non-immunosuppressive or immunosuppressive therapy by doing serial biopsies?

I want more info

Lots of information to check out!

Final thoughts

Sparsentan (FILSPARI) holds promise.
➡️Convincing biological plausibility
➡️Favourable reduction in proteinuria
➡️Early onset effect
➡️Comparable side-effect profile
➡️Safety in study group (though carefully selected)

"Hope is a good thing, maybe the best!"
