Regulatory Discussions Ongoing; Drisapersen Re-Dosing to Start in Q3

LEIDEN, The Netherlands, 2014-05-20 13:00 CEST (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 first quarter ending March 31, 2014
and provided an update on the next steps for its exon-skipping platform for the
treatment of Duchenne Muscular Dystrophy (DMD). 

Hans Schikan, CEO of Prosensa said, 'We have made excellent progress during
this period, and are very pleased that we are now in a position to commence
re-dosing with drisapersen of boys that have previously participated in
drisapersen trials beginning in the third quarter of 2014. In addition, our
250-patient Natural History study, designed to better understand the disease
progression of DMD, has almost completed enrollment.' 

'We are encouraged by our ongoing interactions with the regulatory authorities,
in both the United States and Europe, and remain on track to communicating a
potential regulatory path forward for drisapersen by the end of June,' he
added. 'Prosensa is dedicated to enabling long term patient access to
drisapersen and its follow-on candidates as novel treatments for DMD. We are
determined to accomplish this as soon as possible.' 

Recent Corporate Highlights

-- Updates on the Drisapersen Development Program

  -- On January 13, we announced that we regained the rights to drisapersen from
     GSK and retained the rights to all other programs for the treatment of DMD.
     Prosensa now has full, unencumbered rights to continue the development of
     drisapersen in addition to each of our other DMD programs. Since then, we
     have made substantial progress in the transfer of the drisapersen program
     from GSK.
     
  -- On March 17, encouraging 48-week data from Prosensa's U.S. Phase II
     placebo-controlled study of drisapersen for the treatment of boys with DMD
     (DEMAND V, DMD114876) were presented by the principal investigator, Craig
     M. McDonald, M.D., Professor and Chair of Physical Medicine &
     Rehabilitation and Professor of Pediatrics at the University of California,
     Davis School of Medicine, at the Muscular Dystrophy Association 2014
     Clinical Conference in Chicago, Illinois (March 16-19). The results of this
     51 patient-study indicated that, compared to placebo, boys in the
     higher-dose drisapersen group (6 mg/kg once weekly) experienced
     stabilization and even improvements in their muscle function and physical
     activity as measured by the six-minute walk test (6MWT) for the 24-week
     treatment phase and maintained this improvement during the 24-week
     no-treatment follow-up period. Additionally, when evaluating the
     percent-predicted six-minute walk distance (6MWD), a clinically meaningful
     treatment difference of 5.2% was observed at week 24 and 4.8% at week 48.
     
  -- On April 30, Dr. Nathalie Goemans, Head of the Neuromuscular Reference
     Center for Children at the University Hospitals Leuven (UHL) in Belgium and
     a key investigator in the drisapersen clinical program presented detailed
     data up to week 48 (total of 96 weeks of treatment) from the second
     open-label extension study of drisapersen in 113 boys with DMD (DEMAND IV,
     DMD114349), who had previously completed a 48-week, double-blind,
     placebo-controlled treatment phase in one of two feeder studies (DEMAND II,
     DMD114117 and DEMAND III, DMD114044), during the 66th American Academy of
     Neurology (AAN) Annual Meeting in Philadelphia, PA. The data are supportive
     of the hypothesis that treating earlier in the disease and treating for a
     longer duration confers a treatment benefit for boys with DMD.
     
  -- On May 1, we confirmed that following positive feedback from patients and
     investigators regarding the willingness and desire of patients to go back
     on drisapersen and encouraging analyses of further clinical trial data, we
     will re-dose an initial group of boys, beginning with North America &
     Europe, in the third quarter of 2014.

-- Other Research & Development Update

  -- Twelve abstracts from Prosensa and its collaborators have been accepted for
     either poster or oral presentations for the 19th International World Muscle
     Society Congress, taking place in Berlin, Germany, October 7-11, 2014.
     
  -- PRO044, the next most advanced product candidate, addresses a separate
     sub-population of up to 6% of DMD patients. PRO044 has completed a Phase
     I/II study in Europe, and results were presented in October 2013. An
     extension study for PRO044 is planned for the second half of this year.
     
  -- PRO045 and PRO053 (each addressing a population for up to 8% of all DMD
     patients) are currently in phase I/II clinical trials. We expect data for
     PRO045 in the fourth quarter of 2014 and for PRO053 in the first quarter of
     2015. We expect confirmatory studies for these compounds to start in the
     first half of 2015.
     
  -- PRO052 and PRO055 are in advanced preclinical development.
     
  -- PROSPECT, which includes a new and innovative application our RNA
     modulation technology platform, applies multiple exon skipping. Initial
     efforts in the PROSPECT program are focused on the exon 10 to 30 region in
     the dystrophin gene: a 10 to 30 multiple skip could be applicable to 13% of
     all DMD patients. In vivo studies are currently ongoing.
     
  -- Natural History Study: 247 patients have been enrolled to date. The purpose
     of the study is to characterize the natural history and progression of DMD
     to help inform the design of future studies, to capture biomarkers of
     safety and disease progression and to provide comparative data for the
     development of rare exons for which formal controlled trials are not
     feasible.

-- Supervisory Board Appointment

  -- On April 8, Prosensa announced that Michael S. Wyzga, former CEO of Radius
     Health and CFO of Genzyme Corporation, was nominated for appointment to its
     Supervisory Board. The appointment of Mr. Wyzga will be submitted to a
     shareholder vote at the next shareholders' meeting on June 17, 2014.

Financial Highlights

  -- Cash Position and Cash Consumption: 
Prosensa's cash and cash equivalents as of March 31, 2014 were [Eur]77.4
     million, compared to [Eur]82.2 million as of December 31, 2013. The
decrease in 
     cash and cash equivalents was mainly due to operating activities. The
     company's cash consumption, excluding cash flows from financing for the
     three months ended March 31, 2014 was [Eur]4.9 million.
     
  -- Revenue: 
Revenue for the three months ended March 31, 2014 was [Eur]14.8 million,
     compared with [Eur]2.4 million in 2013 due to an increase in license
revenue of 
     [Eur]13.3 million and a decrease in collaboration revenue of [Eur]0.9
million. 
     License revenue for the three months ended March 31, 2014 in an amount of
     [Eur]14.7 million was exclusively related to the termination of the
research 
     and collaboration agreement with GSK. This was due to a one-time release of
     previously deferred revenue balances as well as [Eur]0.2 million revenue
     related to other services delivered under the research and collaboration
     agreement with GSK. In the three months ended March 31, 2014, collaboration
     revenue was minimal due to the termination of the research and
     collaboration agreement.
     
  -- R&D Expense: 
Research and development expense was [Eur]5.3 million for the three months
     ended March 31, 2014, compared to [Eur]4.1 million for the comparable
period in 
     2013. PRO044 has completed a Phase I/II study in Europe, and results were
     presented in October 2013. An extension study for PRO044 is planned for the
     second half of this year which resulted in lower expenses in the three
     month period ended March 31, 2014 compared to the corresponding period in
     2013. During the three month period ended March 31, 2014, we incurred
     expenses for the Phase I/II studies of both PRO045 and PRO053. Our research
     and development expenses increased substantially in connection with these
     clinical trials. In the three month period ended March 31, 2014 we also
     incurred research and development expenses for drisapersen as a result of
     the termination of the research and collaboration agreement with GSK, in
     addition to expenses for our other projects, such as the Natural History
     study, PROSPECT, PRO052 and PRO055.
     
  -- G&A Expense: 
General and administrative expense increased from [Eur]1.8 million to [Eur]2.5
     million in the three months ended March 31, 2013 and 2014, respectively.
     The increase is primarily due to share-based compensation expense and costs
     associated with operating as a public company.
     
  -- Net income/(loss): 
Net income for the three months ended March 31, 2014 was [Eur]7.3 million or
     [Eur]0.20 per share ([Eur]0.19 diluted income per share), compared to a
loss of 
     [Eur]3.5 million or [Eur]0.12 per share ([Eur]0.12 diluted loss per
share), for the 
     comparative period in 2013.

About DMD

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.
