FERRING PHARMACEUTICALS ANNOUNCES LAUNCH OF EUFLEXXA™ FOR OSTEOARTHRITIS KNEE PAIN
More Patients Treated with EUFLEXXA™ Symptom-Free at End of 12-Week Study Than Those Treated With the Leading Therapy in its Class
Suffern, NY – November 14, 2005 – Ferring Pharmaceuticals Inc. announced today the launch of EUFLEXXA™ (highly purified hyaluronan) for the treatment of pain caused by knee osteoarthritis (OA). It is the first and only non-avian* derived hyaluronic acid (HA) indicated for a three-injection treatment regimen for patients who have failed to respond adequately to conservative non-pharmacologic therapy and simple analgesics. At the end of a 12-week study, significantly more patients treated with EUFLEXXA™ were symptom-free (p=0.038) than those treated with Synvisc**, the leading HA product in its class.1
“EUFLEXXA™ is a new treatment option that can help millions of people who live with painful knees,” said Wayne C. Anderson, president, Ferring Pharmaceuticals. “It is proven to offer better drug-free symptom relief over a 12-week period than the current leading HA therapy. Additonally, it offers proven safety and efficacy with significantly fewer joint effusions and less use of simple analgesics than Synvisc. Not surprisingly, patients reported higher satisfaction with EUFLEXXA™.”
Clinical Advantages
In a prospective, multicenter, randomized, double-blind controlled trial, 321 patients with
confirmed knee osteoarthritis were randomized to treatment with either EUFLEXXA™ (n=160) or
Synvisc (n=161). The Western Ontario McMaster Universities Osteoarthritis (WOMAC) Index
pain subscale was the primary efficacy measure. Both products were administered as a course
of three weekly injections, with follow-up evaluations at weeks 3, 6 and 12. Both treatment
groups experienced statistically significant improvements from baseline (p=0.0001).
EUFLEXXA™ (WOMAC pain score = 29.8 mm (-61.6%)) was shown to be comparable in
efficacy to Synvisc (WOMAC pain score = 28.8 mm (-54.9%)).1 At the study endpoint, 63% of
patients treated with EUFLEXXA™ were symptom-free compared with 52% of those treated with
Synvisc (p=0.038), as determined by a VAS (100-mm visual analog scale) score of <20 for the
average of the five WOMAC pain questions.1
EUFLEXXA™ also showed a significant advantage over Synvisc in the number of
patients requiring supplemental simple analgesics (p=0.013), joint effusion (p=0.0015) and
patient satisfaction (p=0.03). For patient satisfaction, 50% of EUFLEXXA™ patients were ‘very
satisfied’ with treatment results compared to 37% for the Synvisc group. A subanalysis
performed on patients with unilateral OA found that only 49% of patients treated with
EUFLEXXA™ used supplemental simple analgesics compared to 82% of those treated with
Synvisc (p=0.001).1
About EUFLEXXA™
EUFLEXXA™ is the first and only non-avian derived hyaluronic acid approved in the
U.S. for the treatment of pain caused by knee osteoarthritis. Since it is not derived from an
avian source (chicken or rooster combs), the risk of related reactions is eliminated.2,3 In
addition, the process used to manufacture EUFLEXXA™ results in ultra-high-purity HA with
properties similar to the HA in human synovial fluid. EUFLEXXA™ is also free of chemical crosslinking
which minimizes the risk of related reactions.2-7
EUFLEXXA™ received approval from the U.S. Food and Drug Administration (FDA) on December 3, 2004, and is also approved in Israel and the European Union. Ferring acquired the product in July 2005 as part of its acquisition of the global biologics manufacturing business of Savient Pharmaceuticals, Inc.
About Hyaluronic Acid
HA is a viscous, elastic liquid that is naturally found in many tissues of the body and in
high concentrations in joint cartilage and synovial fluid. Within a joint, HA is essential to water
balance, viscosity, lubrication and the structure of cartilage.8 In cartilage, HA binds to other
molecules, helping it withstand weight-bearing force and movement of the joint. Inside the knee
joint, HA provides a cushion to protect the joint from mechanical damage and acts as both a
shock-absorbing fluid and regulator of water and metabolites.
Osteoarthritis and the General Population
The Arthritis Foundation estimates that 66 million Americans are affected by arthritis,
half of whom are unaware of available treatments, and that the disease costs the U.S. economy
more than $86.2 billion annually. The Foundation also estimates that 21 million American adults
suffer from osteoarthritis.9 Osteoarthritis, a form of arthritis, affects certain parts of the body,
most commonly the knee. Over time, articular cartilage in the knee loses elasticity and
becomes worn. As a result, the bony surfaces of the joint can grind together and eventually
wear the cartilage away entirely. This leads to symptoms of pain, stiffness and impaired joint
movement. There are a wide range of treatment options for knee OA, including behavior
modification, drug therapy, injections within the joint and knee replacement surgery.
Non-steroidal anti-inflammatory drugs (NSAIDs) are common first-line pharmacologic
treatments for knee pain relief. Serious side effects and risks (ie. potentially life-threatening
stomach bleeding and kidney disease) have been associated with such treatments.
The effectiveness of different treatments varies from person-to-person and with the
severity of the condition. Treatment options are generally a shared decision between the
patient and his/her physician with total knee replacement surgery usually sought as the last
option.
