Recordati S.p.A. SUBMITS FILE FOR APPROVAL OF SILODOSIN TO THE EMEA
RECORDATI SUBMITS FILE FOR APPROVAL OF
SILODOSIN TO THE EMEA
Milan, 21 November 2008 - Recordati announces that it has submitted a
marketing approval authorization (MAA) request for silodosin, a new
compound indicated for the treatment of the signs and symptoms of benign
prostatic hyperplasia (BPH), to the EMEA (European Medicines Agency). This
submission will follow the centralized approval procedure with the British
MHRA acting as Rapporteur and the Italian AIFA as Co-Rapporteur. Approval
is expected in the first half 2010 and the product launch could take place
by end 2010 or beginning 2011.
Benign prostatic hyperplasia (enlargement of the prostate), characterized
by urination difficulties (such as weak stream, increased frequency and a
sense of urgency, nocturia), is the most frequent reason for patients to
see a urologist. The prevalence of this condition is increasing due to the
progressive ageing of the population. BPH is frequently observed in men
over fifty and its symptoms significantly reduce quality of life.
Silodosin is a new drug indicated for the symptomatic treatment of BPH. It
is a powerful antagonist of the á1 adrenergic receptors. In particular,
silodosin has a very high affinity for the á1A receptors. Blockade of the
á1A receptors leads to a rapid increase in urinary flow-rate and to an
improvement in symptoms associated with BPH. The compound was originally
developed by Kissei Pharmaceutical Co. Ltd., in Japan and is patent
protected until 2018 (including SPC) in Europe with clinical data
exclusivity until 2020. Silodosin has been obtained under license by
Recordati for the whole of Europe (45 countries) and for a further 18
countries in the Middle East and Africa. Recordati also has the right to
appoint co-marketers where deemed appropriate.
Worldwide development of the drug was conducted jointly by Watson
Pharmaceuticals in North America (where approval has already been granted
by the FDA and where launch is expected to take place in early 2009), by
Recordati for its territories, and by Kissei Pharmaceutical Co. for the
rest of the world.
In two Phase III placebo‑controlled clinical trials conducted in the
US by Watson Pharmaceuticals and in one placebo- and active-controlled
trial conducted in Europe by Recordati, over 800 patients received
silodosin 8mg once daily. In these studies, patients treated with silodosin
had a significant decrease in BPH symptoms, both irritative (frequency,
urgency, nocturia) and obstructive (hesitancy, incomplete empting
intermittency, weak stream). In addition, an improvement in the quality of
life linked to urinary symptoms (measured by the International Prostate
Symptom Score, IPSS) was observed with silodosin. Furthermore, in the
active-controlled study conducted in Europe, silodosin 8mg once daily was
not inferior to tamsulosin 0.4mg once daily, with an adjusted mean
difference between treatments in the IPSS Total Score in favour of
silodosin.
The significant improvement in BPH symptoms was observed within the first
week of treatment, and was maintained long-term. In addition, significant
improvements in the maximum urine flow-rate (Qmax) were evident within a
few hours after the first dose of silodosin, and were also maintained
long-term.
The safety of silodosin was extensively evaluated in a total of 1600
patients. As should be expected for a drug with low affinity for á1B
adrenergic receptors, only minimal cardiovascular side-effects were
observed. No changes were seen in supine blood pressure or heart-rate, and
the incidence of orthostatic hypotension was very low (1.2% with silodosin,
versus 1.0% with placebo). Furthermore, no effects on cardiac
repolarization were observed, even at high doses of silodosin. Retrograde
ejaculation (i.e., orgasm with reduced semen), due to silodosin's selective
receptor binding properties, was the most frequent adverse reaction
reported. However, this did not represent a safety concern (the dropout
rate due to retrograde ejaculation were very low), and is reversible upon
discontinuation of the treatment.
Urief® (silodosin) is successfully marketed in Japan by Kissei in
cooperation with Daiichi Sankyo Pharmaceutical Co., Ltd. since May of 2006
with annual sales of EUR 86 million and a market share at September 2008
of around 20%. The market for the class of drugs to which silodosin
belongs, in the five main European countries where Recordati has marketing
rights, is currently of around EUR 800 million per year. Furthermore,
within this class of drugs, there are currently no new molecules in
advanced development.
"The introduction of silodosin among our future new corporate products will
allow Recordati to consolidate its presence in the therapeutic area of
urology, an area within which it has been present for many years with
flavoxate, the first Italian active ingredient to be approved by the FDA in
the U.S.A., and more recently with Kentera®, a drug indicated for the
treatment of urinary incontinence" stated Giovanni Recordati, Chairman and
Chief Executive Officer. "Recordati has been conducting original innovative
research in the area of urology for a long time and has matured specific
know-how that is globally recognized."
Recordati, established in 1926, is a European pharmaceutical group, listed
on the Italian Stock Exchange (Reuters RECI.MI, Bloomberg REC IM, ISIN IT
0003828271),with a total staff of over 2,400, dedicated to the research,
development, manufacturing and marketing of pharmaceuticals. It has
headquarters in Milan, Italy, operations in the main European countries,
and a growing presence in the emerging markets of Eastern Europe. A
European field force of over 1,300 medical representatives promotes a wide
range of innovative pharmaceuticals, both proprietary and under license, in
a number of therapeutic areas including a specialized business dedicated to
treatments for rare diseases. Recordati's current and growing coverage of
the European pharmaceutical market makes it a partner of choice for new
product licenses from companies which do not have European marketing
organizations. Recordati is committed to the research of new drug entities
within the cardiovascular and urogenital therapeutic areas in which its
research team has proven scientific competence and a track record of
discovery and development of original drugs, the most recent of which,
lercanidipine, a latest generation calcium channel blocker for the
treatment of hypertension, is the company's leading product. Consolidated
revenue for 2007 was EUR 628.4 million, operating income was EUR 131.5
million and net income was EUR 84.9 million.
