Calliditas Therapeutics AB (CALT)

$CALT $38 STOCKHOLM, May 28, 2024 /PRNewswire/ -- Calliditas Therapeutics AB (Nasdaq: CALT) (Nasdaq Stockholm: CALTX) ("Calliditas"), today announced the presentations of an additional efficacy analysis of Nefecon (TARPEYO® (budesonide) delayed release capsules)) as well as a real-world analysis of the use of systemic glucocorticoids (SGC) in IgA nephropathy (IgAN). These were presented at ERA 2024 virtually and in Stockholm on May 23 - 26, 2024.

The presented efficacy analysis of Nefecon and sparsentan showed that treatment with Nefecon for 9 months was associated with estimated glomerular filtration rate (eGFR) benefit compared with continuous treatment with sparsentan.

Additionally, the findings of a real-world analysis of challenges associated with the use of systemic glucocorticoids demonstrate significant side effects and costs for IgAN patients treated with systemic glucocorticoids (SGC), such as Prednisone and Prednisolone.

"It was wonderful to participate in ERA 2024 and present data contributing to the discussion on the need for effective treatments in IgAN," said Richard Philipson, Chief Medical Officer of Calliditas, " We continue to gather evidence that highlights the importance of treating the underlying autoimmune pathogenesis associated with IgAN, and we believe TARPEYO, as the only approved immunomodulating therapy designed to target the production of Gd-IgA1, has the potential to become a cornerstone therapy in IgAN."

Poster presentation details are below and will be available on the Presentations and Publications page on the Calliditas' corporate website following the meeting.

Title: "Matching-adjusted indirect comparison of eGFR in patients with immunoglobulin A nephropathy treated with Nefecon (TRF budesonide) or sparsentan"

A matching-adjusted indirect comparison (MAIC) methodology is a widely accepted and relevant methodology for comparing treatments across trials in the absence of head-to-head comparisons. Here the effects of Nefecon, marketed as TARPEYO® and sparsentan, marketed as FILSPARI™, on kidney function deterioration in patients with IgAN were compared, as assessed by eGFR change from baseline at 9, 12 and 24 months. Results from the MAIC showed significantly favorable effects of Nefecon versus sparsentan on eGFR across all time points analyzed. Mean differences in the absolute change in eGFR of 5.68mL/min/1.73 m2 (95% credible interval [Crl] 3.14, 8.20; p
