PEAPACK, NJ -- November 19, 2001 -- Pharmacia Corporation today announced
that the Committee for Proprietary Medicinal Products (CPMP), which is
responsible for evaluating drug products in the European Union for the
European Agency for Evaluation of Medicinal Products (EMEA), has recommended
granting a Marketing Authorization for Dynastat® (parecoxib sodium for
injection) for the short term treatment of postoperative pain.
Dynastat -- the first injectable cyclooxygenase (COX)-2 specific inhibitor
-- will have a single Marketing Authorization with unified labeling that
will be valid in all 15 European Union (EU) member states, as well as Norway
and Iceland.
"We are excited that CPMP has voted to approve Dynastat for the
treatment of postoperative pain," said Carrie Cox, Executive Vice
President and Head of Global Prescription Business at Pharmacia Corporation.
"In clinical trials, Dynastat provided fast and long-lasting relief of
post-operative pain with fewer of the gastrointestinal and platelet effects
typically associated with previously available nonsteroidal
anti-inflammatory drugs [NSAIDs], and reduced the need for opioid
analgesics. We are confident that Dynastat will help fulfill the need for
improved pain medications in the EU and around the globe."
The Committee for Proprietary Medicinal Products formed its positive
opinion based on a review of the results of Dynastat clinical studies
involving patients in a variety of surgical models, including hip and knee
replacement, abdominal gynecologic surgery, coronary artery bypass graft
surgery, and third molar extraction with bone resection.
In the clinical trials program, Dynastat was compared with placebo as
well as with the opioid analgesic, morphine, and the conventional NSAID,
ketorolac, both of which are widely used to control postoperative pain.
In a Phase III, double-blind, placebo-controlled study of 208 patients
who had undergone knee-replacement surgery, a single intravenous (IV) dose
of Dynastat (40 mg) was found to be as effective as a single IV dose of
ketorolac (30 mg) and more effective than a single IV dose of morphine (4
mg). Dynastat 40 mg IV also provided superior and longer-lasting analgesia
compared with morphine 4 mg IV in two Phase III, placebo-controlled,
single-dose studies among patients who had undergone total hip-replacement
or abdominal gynecologic surgery.
Multiple Phase III studies demonstrated that patients who received
Dynastat 40 mg IV required significantly less opioid analgesics than
patients treated with opioids alone, while still maintaining the desired
level of pain control. In studies using three different surgical models,
administration of Dynastat reduced morphine consumption by 20 to 40 percent.
In addition, patients treated with Dynastat were more likely to discontinue
morphine patient-controlled analgesia within 24 hours after surgery.
In clinical studies, administration of Dynastat was associated with
significantly fewer of the side effects that typically accompany treatment
with conventional NSAIDs (e.g., bleeding and gastrointestinal ulceration) or
opioids (e.g., respiratory depression). The most common side effects of
Dynastat were nausea, vomiting, and itching, all of which occurred at a
similar rate among patients receiving placebo.
Dynastat should not be administered to patients with aspirin-sensitive
asthma or allergic reactions to aspirin or other NSAIDs, or to women in
their third trimester of pregnancy.
In addition, Dynastat should be used with caution to treat pain following
coronary artery bypass graft surgery. As with all NSAIDs, serious
gastrointestinal tract ulcerations can occur without warning symptoms.
Dynastat is the first injectable COX-2 specific inhibitor. Like other
agents in its class, the drug works by selectively inhibiting the
cyclooxygenase (COX)-2 enzyme, which plays a critical role in the response
to injury (pain and inflammation). At therapeutic doses, Dynastat does not
appear to affect the COX-1 enzyme, which helps to maintain normal function
in the stomach and blood.
