The 15th International Symposium on IgA nephropathy accepts Calliditas Therapeutics abstracts

Non Regulatory

Calliditas Therapeutics AB (publ) (”Calliditas”) today announced that five abstracts connected to its successful Phase 2 study NEFIGAN have been accepted by the International IgA Nephropathy Network meeting (IIgANN) in Buenos Aries, Argentina, September 27-29, 2018.

The new results stem from exploratory analyses and extended post-hoc analyses of the randomized, double-blind controlled Phase 2b study NEFIGAN which Calliditas conducted with 149 IgA nephropathy (IgAN) patients at risk of developing ESRD. In 2017, the primary results from nine months’ treatment with either Nefecon or placebo were published in The Lancet. They demonstrated the effectiveness of Nefecon in reducing proteinuria and stabilizing the kidney function as well as confirming that the treatment was safe and tolerable for the patients. The NEFIGAN study strongly supports that local treatment of the mucosal immune system of the GI tract with budesonide is effective in reducing renal leakage and preventing loss of kidney function.

The following abstracts are accepted by the 15th International Symposium on IgA nephropathy: 

  • Title: Extent of segmental glomerulosclerosis in IgA nephropathy is associated with the level of eGFR response to TRF-budesonide (Nefecon)
    Authors: Maria Soares, Andrew Stone, Jonathan Barratt and Ian Roberts
  • Title: Treatment of IgA nephropathy with Nefecon, a targetedrelease formulation of budesonide – extended posthoc results from the Nefigan trial 
    Authors: Bengt Fellström, Jonathan Barratt, Jürgen Floege et al, on behalf of NEFIGAN investigators
  • Title: Targeted Release-Budesonide modifies mucosal IgA responses and possibly gut permeability in IgA nephropathy 
    Authors: Masahiro Muto, Jasraj Bhachu, Jeremy Brown, Karen Molyneux, Rosanna Coppo and Jonathan Barratt
  • Title: Targeted Release-Budesonide modifies circulating IgA-IgG immune complex levels and levels of poorly O-galactosylated IgA in IgAN 
    Authors: Jasraj Bhachu, Katrin Scionti, Masahiro Muto, Karen Molyneux and Jonathan Barratt
  • Title: Nefecon, an oral disease modifying treatment for progressive IgA nephropathy. The strategy behind developing proteinuria as surrogate endpoint for accelerated approval 
    Authors: Johan Häggblad, Ann-Kristin Myde and Jens Kristensen

All abstracts and summaries of the sessions will be published in a special number of the scientific journal Kidney Diseases.

The information was submitted for publication, through the agency of the contact person set out below, at 8:00 am CEST on August 6, 2018.

About Calliditas
Calliditas Therapeutics is a specialty pharmaceutical company based in Stockholm, Sweden, focused on developing high quality pharmaceutical products for patients with a significant unmet medical need in niche indications, in which the Company can partially or completely participate in the commercialization efforts. The Company is focused on the development and commercialization of the product candidate Nefecon, a unique formulation optimized to combine a time lag effect with a concentrated release of the active substance budesonide, within a designated target area. This patented, locally acting formulation is intended for treatment of patients with the inflammatory renal disease IgA nephropathy. Calliditas Therapeutics aims to take Nefecon through a global Phase 3 study to commercialization. The company is listed on Nasdaq Stockholm (tícker: CALTX). Visit for further information.

About Nefecon 
Nefecon is a potential treatment for patients with IgAN at risk of developing ESRD. It is a proprietary oral formulation of budesonide, designed to deliver budesonide to the ileum where the so-called Peyer’s patches, which harbor the majority of B-cells producing IgA antibodies, are found. By delivering budesonide locally instead of systemically, Nefecon greatly reduces the side-effect burden observed with high dose steroid treatment while optimizing the effective dose level of the drug where it is required. Budesonide has been used to treat patients with asthma, inflammatory bowel disease and allergic rhinitis for over 35 years. It is rapidly degraded soon after entering the circulatory system, making it an ideal basis for drugs such as Nefecon because local delivery to disease tissue minimizes the systemic effects seen with other corticosteroids.
Nefecon has been granted orphan drug designation for IgAN by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA).

About IIgANN 
The International IgA Nephropathy Network (IIgANN) was established in 2000 based on The International IgA Nephropathy Club that started in 1987. The purpose with IIgANN is to increase the awareness of the disease since it was felt that the clinical impact of IgAN was underappreciated by nephrologists and general physicians in many countries. This year’s IIgANN meeting will also mark the 50th anniversary of the initial description of IgAN by Dr. J Berger and Dr. N. Hinglais in 1968. Approximately 175 participants are expected at this global meeting focused exclusively on IgAN.
