Sustained Efficacy of EMPAVELI: New data from the Phase 3 VALIANT study show that EMPAVELI (pegcetacoplan) significantly reduces proteinuria by 68% and maintains this reduction for one year, with one-third of patients achieving complete remission.
Comparative Effectiveness: Indirect treatment comparisons indicate that EMPAVELI is superior to iptacopan in lowering proteinuria levels and achieving composite renal endpoints in patients with C3 glomerulopathy (C3G).
Safety Profile: EMPAVELI demonstrated a favorable safety and tolerability profile, with no new safety signals reported, although it carries a risk of serious infections due to its mechanism as a complement inhibitor.
Transformative Potential: As the only approved treatment for C3G and primary immune complex membranoproliferative glomerulonephritis (IC-MPGN) in patients aged 12 and older, EMPAVELI has the potential to significantly improve care for patients at high risk of kidney failure.
