Sobi

Stockholm – November 03, 2026 -- Sobi (STO: SOBI) will present six abstracts on two late-stage gout assets, pozdeutinurad (AR882) and nanoencapsulated sirolimus plus pegadricase (NASP), at ACR Convergence 2026, the American College of Rheumatology annual meeting, in Orlando, Florida, on 6–11 November 2026.

Phase 3 REDUCE-2 results for pozdeutinurad headline the program

The presentations include results from the Phase 3 REDUCE-2 study of pozdeutinurad, an investigational once-daily oral, highly selective URAT1 inhibitor for uncontrolled gout. REDUCE-2 is one of two 12-month, randomised, double-blind, placebo-controlled Phase 3 studies, alongside REDUCE-1, that are evaluating the drug in more than 800 patients. Both trials assess its ability to lower serum urate (SU) in patients with uncontrolled gout.

Earlier Phase 2 studies showed a sustained SU reduction, dissolution of tophi and a generally well-tolerated safety profile, according to Sobi.

STOCKHOLM – October 29, 2026 -- Sobi's investigational gout drug pozdeutinurad (AR882) met the primary endpoint of the Phase 3 REDUCE-2 study, with 69.2% of patients on the 75 mg dose reaching serum urate (SU) below 6 mg/dL at month 6, against 8.1% on placebo. The company is presenting the late-breaking data at ACR Convergence 2026.

Both pozdeutinurad doses beat placebo on the primary endpoint at month 6

REDUCE-2 randomised 811 gout patients to pozdeutinurad 75 mg, pozdeutinurad 50 mg or placebo. In the 50 mg arm, 56.6% of patients achieved SU below 6 mg/dL at month 6. Both doses were significant versus placebo (p<0.0001).

Pozdeutinurad is a once-daily oral, highly selective URAT1 inhibitor. Sobi is developing it for uncontrolled gout, defined as SU above 6 mg/dL with persistent flares and/or tophi despite oral urate-lowering therapy.

Stockholm – October 19, 2026 -- Sobi will present seven accepted abstracts on Aspaveli/Empaveli (pegcetacoplan) at the American Society of Nephrology (ASN) Kidney Week 2026, running 21–25 October in Denver, Colorado, including two oral and five poster presentations.

Oral sessions report 76-week outcomes in two rare kidney diseases

The two oral presentations cover 76-week outcomes with Aspaveli/Empaveli in C3 glomerulopathy (C3G) and primary immune-complex membranoproliferative glomerulonephritis (IC-MPGN). According to Sobi, the data show maintained proteinuria reduction and stabilised eGFR. The package includes a paediatric subgroup analysis from the VALIANT study and its VALE extension.

Stockholm – September 24, 2026 -- Sobi (STO: SOBI) will present new clinical data on its rare-disease drug Gamifant (emapalumab) at the 2026 Annual Meeting of the Histiocyte Society (HS2026), running September 26-29 in Rotterdam, the Netherlands, with a pooled survival analysis nominated for the meeting's top poster prize.

Pooled transplant-survival analysis earns Robert J. Arceci Prize nomination

The accepted abstract set includes a new pooled analysis of pre- and post-transplant survival outcomes in primary haemophagocytic lymphohistiocytosis (HLH), drawing on data across three prospective trials. Sobi said the analysis was selected as one of the ten highest-scoring poster abstracts at HS2026 and has been nominated for the Robert J. Arceci Prize for Best Poster.
