Pharmalink Extends Patent Protection for Nefecon® Treatment for Renal Disease

STOCKHOLM, October 27, 2014 /PRNewswire/ —


Key patent granted in Japan  

Pharmalink AB, a specialty pharma company focused on orphan and niche products, has had an important patent for its late-stage clinical candidate Nefecon® granted in Japan (5608641). Key patents protecting Nefecon have also been granted in the United States, Europe, China and Hong Kong, giving Pharmalink strong patent protection for Nefecon in key pharmaceutical markets around the world.

Nefecon is a potential disease-modifying treatment for patients with primary IgA nephropathy at risk of developing end-stage renal disease. Nefecon has shown positive results in an open-labelled Phase II trial evaluating safety and efficacy and is now being tested in a placebo-controlled randomized Phase IIb study ( The study has been designed to enable an optimal dose of Nefecon to be selected for a Phase III registration trial. Headline data is anticipated in Q3 2015.

Nefecon is an enteric formulation of a locally-acting and potent corticosteroid that down-regulates the disease process in the kidney through suppression of the gastrointestinal immune system thus exploiting the pivotal role the gastrointestinal tract plays in the overall immune response. Early treatment with Nefecon of patients with primary IgA nephropathy at risk of developing end-stage renal disease may slow or halt disease progression and further loss of renal function, and provide an alternative to dialysis and transplantation. Nefecon has received orphan drug designation by the US Food and Drug Administration (FDA).

About IgA Nephropathy 

IgA nephropathy is the most common form of glomerulonephritis (inflammation of the kidney glomeruli). The disease is characterized by deposits, predominantly containing polymeric IgA antibody, in the kidney that cause inflammation and renal damage.

IgA nephropathy can occur at any age, but the clinical onset is commonly during the second or third decades of life. It has been estimated that 20-40% of patients with IgA nephropathy progress to renal failure, often referred to as end-stage renal disease within 5-30 years following diagnosis. This patient population is estimated to at least 200,000 in major markets.

Patients suffering renal failure require dialysis or kidney transplantation. IgA nephropathy accounts for 10% of renal transplants among patients with primary glomerulonephritis in the US and between 7-20% of patients in Europe and Australia in long-term dialysis and renal transplantation programs.

About the Nefigan trial 

The Nefigan trial is a multicenter, randomized, double-blind, placebo controlled study conducted at more than 60 centers in ten European countries. The objective of the study is to evaluate efficacy and safety of two different doses of Nefecon in the treatment of patients with primary IgA nephropathy at risk of developing end-stage renal disease (ESRD), under standardized rigorous blood pressure control with an angiotensin-converting enzyme inhibitor (ACEI) and/or angiotensin II receptor I blocker (ARB).
