THOUSAND OAKS, Calif., and RADNOR, Penn., December 2, 2002 – Amgen (NASDAQ: AMGN) and Wyeth Pharmaceuticals, a division of Wyeth (NYSE: WYE), today announced that supply of the breakthrough biologic, ENBRELâ (etanercept), has been offered over the past 8 weeks to more than 40,000 patients on the ENBREL Prospective Patient List. These patients and their physicians are being notified that they may now order ENBREL.
“We are pleased to be able to deliver on the companies' commitment to release ENBREL supply as it becomes available for these rheumatoid arthritis, juvenile rheumatoid arthritis, and psoriatic arthritis patients,” said Kevin Young, vice president and general manager of Amgen's Inflammation Business Unit. “We have experienced improved efficiencies at the current ENBREL manufacturing facility that have helped enable us to make this large-scale offering of supply to patients.”
“This step is significant in that it opens the door for more patients to benefit from ENBREL, the only TNF receptor therapy distinguished by five years of data supporting its consistent and sustained efficacy and long -term tolerability,” said Joseph Mahady, president North America, Wyeth Pharmaceuticals.
The ENBREL Enrollment Program will remain in effect to help current patients continue to have access to ENBREL. Patients can enroll by calling 1-888-4ENBREL (1-888-436-2735). ABOUT ENBREL ENBREL is the only fully human, anti-TNF therapy approved for use to reduce the signs and symptoms of active arthritis in patients with psoriatic arthritis, and to reduce the signs and symptoms and inhibit the progression of structural damage in patients with moderately to severely active rheumatoid arthritis (RA). ENBREL is the only biologic therapy approved to treat newly diagnosed RA patients, and can be used alone. ENBREL is also approved to reduce the signs and symptoms of moderately to severely active polyarticular-course juvenile rheumatoid arthritis (JRA) in patients 4 years of age and older who have had an inadequate response to one or more disease-modifying antirheumatic drugs (DMARDs).
Rheumatologists have become familiar with the benefits and proven long -term tolerability profile of ENBREL, having treated over 129,000 patients worldwide in over four years of post-marketing experience. –
ENBRELâ (etanercept) acts by binding TNF, one of the dominant inflammatory cytokines or regulatory proteins that play an important role in both normal immune function and the cascade of reactions that causes the inflammatory process of psoriatic arthritis and RA. The binding of ENBREL to TNF renders the bound TNF biologically inactive , resulting in significant reduction in inflammatory activity. Important Treatment Considerations
SINCE THE PRODUCT WAS FIRST INTRODUCED, SERIOUS INFECTIONS, SOME INVOLVING DEATH, HAVE BEEN REPORTED IN PATIENTS USING ENBREL. MANY OF THESE INFECTIONS OCCURRED IN PATIENTS WHO WERE PRONE TO INFECTIONS, SUCH AS THOSE WITH ADVANCED OR POORLY CONTROLLED DIABETES. RARE CASES OF TUBERCULOSIS HAVE ALSO BEEN REPORTED. ENBREL SHOULD BE DISCONTINUED IN PATIENTS WITH SERIOUS INFECTIONS. DO NOT START ENBREL IF YOU HAVE AN INFECTION OF ANY TYPE OR IF YOU HAVE AN ALLERGY TO ENBREL OR ITS COMPONENTS. ENBREL SHOULD BE USED WITH CAUTION IN PATIENTS PRONE TO INFECTION. CONTACT YOUR PHYSICIAN IF YOU HAVE ANY QUESTIONS ABOUT ENBREL OR INFECTIONS.
There have been reports of serious nervous system disorders such as multiple sclerosis, seizures, or inflammation of the nerves of the eyes. Tell your doctor if you have ever had any of these disorders or if you develop them after starting ENBREL. There have also been rare reports of serious blood disorders, some involving death. Contact your doctor immediately if you develop symptoms such as persistent fever, bruising, bleeding, or paleness. It is unclear if ENBREL has caused these nervous system or blood disorders. If your doctor confirms serious blood problems, you may need to stop using ENBREL.
The most frequent adverse events in placebo-controlled RA clinical trials involving 349 adults were injection site reactions (ISR) (37%), infections (35%), and headache (17%). Only the rate of ISR was higher than that of placebo. The most frequent adverse events in a methotrexate-controlled clinical trial of 415 adults with early-stage RA were infections (64%), ISR (34%), and headache (24%). Of these, only the rate of ISR was higher than that of methotrexate. Patients have been observed in clinical trials for over 3 years. The incidence of malignancies has not increased with extended exposure to ENBREL and is similar to the projected background rate. Adverse events in the psoriatic arthritis trial were similar to those reported in RA clinical trials.
In a study of 69 patients with JRA, infections (62%), headache (19%), abdominal pain (19%), vomiting (13%), and nausea (9%) occurred more frequently than in adults. The types of infections reported in JRA patients were generally mild and consistent with those commonly seen in children. Serious adverse reactions reported rarely were chicken pox (3%), gastroenteritis (3%), serious infections (2%), depression/personality disorder (1%), skin ulcer (1%), inflammation in parts of the upper digestive tract (1%), and diabetes (1%).
