FDA approves Vera Therapeutics' Trutakna for IgAN treatment
Vera Therapeutics Inc. received FDA accelerated approval for Trutakna (atacicept-vymj) to reduce proteinuria in adults with IgA Nephropathy at risk of disease progression. The approval was supported by interim Phase 3 ORIGIN 3 trial data showing a 46% reduction from baseline in UPCR and a 42% reduction compared to placebo at 36 weeks. The company anticipates eGFR results in the third quarter of 2026 and plans to submit an sBLA for full approval in the fourth quarter of 2026.

The U.S. Food and Drug Administration (FDA) on Tuesday granted accelerated approval to Vera Therapeutics Inc.'s Trutakna (atacicept-vymj) to reduce proteinuria in adults with primary immunoglobulin A nephropathy (IgAN) who are at risk for disease progression. Following the announcement, the company's stock climbed nearly 9%. The approval is based on the therapy's ability to reduce proteinuria, though long-term evidence demonstrating whether the treatment slows kidney function decline has not yet been established. Continued approval may depend on confirmation of clinical benefit in the ongoing ORIGIN 3 study.
The Biologics License Application (BLA) submission was supported by a prespecified interim analysis from the ongoing Phase 3 ORIGIN 3 trial involving the first 203 participants. Patients treated with Trutakna recorded a 46% reduction from baseline in urine protein-to-creatinine ratio (UPCR). Compared with placebo, the therapy delivered a statistically significant 42% reduction in proteinuria at 36 weeks.
ORIGIN 3 Trial and Future Plans
The ORIGIN 3 trial remains an ongoing study evaluating adults with IgA nephropathy. Participants receive either once-weekly 150 mg subcutaneous Trutakna injections administered at home or a placebo. The study continues in a blinded, placebo-controlled manner to assess changes in kidney function measured by estimated glomerular filtration rate (eGFR). Vera Therapeutics expects those results in the third quarter of 2026. Pending these results, the company plans to submit a supplemental Biologics License Application (sBLA) for full approval in the fourth quarter of 2026.
Competitive Landscape
Novartis AG remains a key competitor in the IgAN treatment space. In April 2025, the FDA granted accelerated approval to Novartis's Vanrafia (atrasentan) for the reduction of proteinuria in adults with IgAN. In February, Novartis shared final results from the Phase 3 ALIGN study, which supported a slowing decline in kidney function in adults with IgAN treated with Vanrafia. Following the trial data, Novartis plans to submit for traditional approval in 2026.
Key Trial Data for Trutakna
| Metric | Result |
|---|---|
| Proteinuria reduction (baseline) | 46% |
| UPCR reduction (vs placebo) | 42% |
| Treatment duration | Week 36 |
Vera Therapeutics shares were up 8.97% at $43.73 at the time of publication on Tuesday.
How will the lack of long-term data regarding kidney function decline impact physician adoption and insurance reimbursement for Trutakna?
Can Trutakna capture significant market share given Novartis's Vanrafia already demonstrated a slowing of kidney function decline in Phase 3 trials?
What are the potential commercial consequences for Vera Therapeutics if the ORIGIN 3 study fails to confirm clinical benefit by the 2026 deadline?
