Pharmalink’s Core Patents for Nefecon® Treatment for Renal Disease Granted in United States, Europe, China and Hong Kong

July 10, 2014

STOCKHOLM, July 10, 2014 /PRNewswire/ –

Pharmalink AB, a specialty pharma company focused on orphan and niche products, has
had core patents for its late-stage clinical candidate Nefecon(R) issued in the key
markets United States, Europe, China and Hong Kong. A patent is pending in Japan.

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 (http://www.nefigan.net).
Pharmalink recently completed patient enrolment of this study, which 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.

The patents issued in the US (US 8,491,932), Europe (EP 2278958) China (200980127272.5
) and Hong Kong (1158510) provide protection around the formulation of Nefecon and its use
as a treatment of glomerulonephritis, including IgA nephropathy, the most common form of
primary glomerulonephritis and a cause of end-stage renal disease. The formulation
technology, TARGIT(R), was licenced by Pharmalink for exclusive use with Nefecon under a
2011 agreement with Archimedes Development Ltd (UK). The suite of recently issued patents
are the result of a very productive formulation development partnership between the

Johan Haggblad, Managing Director of Pharmalink, said: “Nefecon is a disease-modifying
medication and one of the first specifically aimed at addressing the underlying pathology
of progressive IgA nephropathy. The issuance of core patents in key global markets
reinforces the commercial package we are building around Nefecon.”

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).
