LEIDEN, The Netherlands, Aug. 28, 2013 (GLOBE NEWSWIRE) -- Prosensa Holding N.V. (Nasdaq:RNA), the Dutch biopharmaceutical company focusing on RNA-modulating therapeutics for rare diseases with high unmet need, today reported financial results for the quarter ended June 30, 2013.
"We had a transformative second quarter, culminating with our successful IPO at the end of June, raising $89.7M. On July 3, 2013, the date we received our IPO proceeds, our cash and cash equivalents amounted to €94.3 million ($122.2 million), providing a substantial base to support the development of our portfolio especially our rapidly advancing Duchenne muscular dystrophy (DMD) product candidates. We were also very pleased with the results of the phase II DMD114117 double-blind, placebo-controlled study with drisapersen, which we exclusively licensed to GlaxoSmithKline (GSK). The study, which met its primary endpoint, was presented by GSK at the Cold Spring Harbor Conference in April 2013," said Hans Schikan, CEO of Prosensa.
Mr. Schikan continued, "We look forward to an incredibly busy and exciting remainder of the year, particularly as phase III data will become available for drisapersen. To date, more than 300 patients have participated in clinical studies with drisapersen at more than 50 trial sites in 25 countries. We believe that drisapersen, which was recently granted 'Breakthrough Therapy Designation' by the U.S. Food and Drug Administration, may potentially offer DMD patients with an amenable mutation an important, much-needed treatment option and we are dedicated to advancing the rest of our portfolio to help other sub-populations of boys with this devastating neuromuscular disease."
Prosensa's current portfolio includes six compounds for the treatment of DMD, all of which have received orphan drug status in the United States and the European Union. The compounds utilize an innovative technique called exon-skipping to provide a personalized medicine approach to treat different populations of DMD patients.
Recent Corporate Highlights
- On April 11, 2013 GSK presented results for the DMD114117 (DEMAND II) clinical trial. The primary endpoint in this double-blind, placebo-controlled, exploratory study was met and a statistically and clinically meaningful difference of 35 meters in the six-minute walk test between the continuous dosing regimen of 6mg/kg per week and placebo was achieved at 24 weeks. On July 31, 2013, summary results from this study were posted on GSK's Clinical Study Register.
- On June 27, 2013, GSK announced that the U.S. Food and Drug Administration, or FDA, had provided notification that drisapersen has been granted Breakthrough Therapy Designation for the treatment of DMD. Breakthrough Therapy Designation is an FDA program intended to facilitate and expedite development and review of new drugs to address unmet medical need in the treatment of serious or life-threatening conditions.

About Prosensa Holding N.V.
Prosensa (Nasdaq:RNA) is an innovative biotechnology company engaged in the discovery and development of ribonucleic acid-modulating, or RNA-modulating, therapeutics for the treatment of genetic disorders. Our primary focus is on rare neuromuscular and neurodegenerative disorders with a large unmet medical need, including Duchenne muscular dystrophy, myotonic dystrophy and Huntington's disease. Our clinical portfolio of RNA-based product candidates is focused on the treatment of Duchenne muscular dystrophy, or DMD. Each of our DMD compounds has been granted orphan drug status in the United States and the European Union. Our first product candidate, drisapersen, can address a variety of mutations in the dystrophin gene, such as a deletion of exon 50 or exons 48 to 50.
DMD is one of the most prevalent rare genetic diseases globally affecting up to 1 in 3,500 boys and is invariably fatal. There is currently no approved disease-modifying therapy for DMD. The progressive muscle-wasting that characterizes this disease is caused by inadequate production of dystrophin, a protein necessary for muscle function, as a result of mutations in the dystrophin gene. The different mutations, which are mostly deletions of one or more exons, found in the dystrophin gene result in distinct sub-populations of DMD patients. We are designing product candidates to address several sub-populations using our platform technology.
About exon skipping and RNA modulation
The dystrophin gene is the largest gene in the body, consisting of 79 exons. Exons are small sequences of genetic code which, via an intermediate step involving RNA, lead to the assembly of sections of protein. In DMD, when certain exons are mutated/deleted, the RNA cannot read past the fault. This prevents the remainder of the exons from being read, resulting in a non-functional dystrophin protein and the severe symptoms of DMD. RNA-based therapeutics, specifically antisense oligonucleotides inducing exon skipping, are currently in development for DMD. These antisense oligonucleotides skip an exon next to a defective exon and thereby correct the reading frame, enabling the production of a novel, largely functional dystrophin protein. Prosensa's exon skipping technology was licensed from Leiden University Medical Center.
