Re: Re: what was the Vioxx news?

[Guest guest]

Hi ,

Thank you for this information. I will certainly talked with my doctor - and my druggist - about this.

Thank you for going to so much trouble.

SEE YOUR DOCTOR if you are worried: (this is response to the person that asked what the news was about Vioxx)The following is a letter that the FDA made MERCK send to all the doctors. You can read it and decide if it has any relevance to your medical history. The main point is this: “The information below should be taken into consideration and caution should be exercised when VIOXX® (rofecoxib) is used in patients with a medical history of ischemic heart disease.”Don’t forget that this should be a decision that is made with your doctor. As pointed out before there are other COX-2 drugs out there. The problem comes in if they do not work for you and this one does. All of these COX-2 drugs are much safer than the old NSAIDs (naproxen, ibuprofen etc.) which can cause or are more likely to cause bleeding ulcers.Read the stuff for yourself and then have an informative conversation with your doctor. If not satisfied try another doctor until you are satisfied you are getting an over whelming opinion about what the best judgment of the entire medical community is. That is my advice if I were worried about it... that is.THE PDF file is much easier to read than what I copied and pasted here into this e-mail. The link to the FDA site to down load that PDF file is: http://www.fda.gov/medwatch/SAFETY/2002/vioxx_deardoc.pdfSee other links below as well.April 2002Dear Healthcare Professional:Merck & Co., Inc., would like to bring to your attention recent changes to the current PrescribingInformation and Patient Product Information for VIOXX® (rofecoxib tablets and oral suspension). VIOXXis a nonsteroidal anti-inflammatory drug (NSAID) that was approved by the United States Food andDrug Administration (FDA) in May 1999 for relief of the signs and symptoms of osteoarthritis (OA), themanagement of acute pain in adults, and the treatment of primary dysmenorrhea.The Prescribing Information has been revised to reflect the results of the VIOXX GastrointestinalOutcomes Research (VIGOR) Study and the FDA approval of VIOXX for the relief of the signs andsymptoms of rheumatoid arthritis in adults. Excerpts of the changes to the Prescribing Informationare provided below.* * * * *

CLINICAL STUDIESRheumatoid Arthritis (RA)VIOXX has demonstrated significant reduction of joint tenderness/pain and joint swelling compared toplacebo. VIOXX was evaluated for the treatment of the signs and symptoms of RA in two 12-weekplacebo- and active-controlled clinical trials that enrolled a total of approximately 2,000 patients.VIOXX was shown to be superior to placebo on all primary endpoints (number of tender joints, numberof swollen joints, patient and physician global assessments of disease activity). In addition, VIOXX wasshown to be superior to placebo using the American College of Rheumatology 20% (ACR20)Responder Index, a composite of clinical, laboratory, and functional measures of RA. VIOXX 25 mgonce daily and naproxen 500 mg twice daily showed generally similar effects in the treatment of RA.A 50-mg dose once daily of VIOXX was also studied; however, no additional efficacy was seencompared to the 25-mg dose.Special StudiesThe VIGOR study was designed to evaluate the comparative GI safety of VIOXX 50 mg once daily(twice the highest dose recommended for chronic use in OA and RA) versus naproxen 500 mg twicedaily (common therapeutic dose). The general safety and tolerability of VIOXX 50 mg once daily versusnaproxen 500 mg twice daily was also studied. VIGOR was a randomized, double-blind study (medianduration of 9 months) in 8076 patients with rheumatoid arthritis (RA) requiring chronic NSAID therapy2(mean age 58 years). Patients were not permitted to use concomitant aspirin or other antiplateletdrugs. Patients with a recent history of myocardial infarction or stroke and patients deemed to requirelow-dose aspirin for cardiovascular prophylaxis were to be excluded from the study. Fifty-six percentof patients used concomitant oral corticosteroids. The GI safety endpoints (confirmed by a blindedadjudication committee) included:PUBs—symptomatic ulcers, upper GI perforation, obstruction, major or minor upper GI bleeding.Complicated PUBs (a subset of PUBs)—upper GI perforation, obstruction or major upper GI bleeding.Study ResultsGastrointestinal Safety in VIGORThe VIGOR study showed a significant reduction in the risk of development of PUBs, includingcomplicated PUBs in patients taking VIOXX® (rofecoxib) compared to naproxen (see Table 1).

A similar risk reduction for PUBs and complicated PUBs(approximately 50%) was also maintained in patients with or without Helicobacter pylori infection orconcomitant corticosteroid use.Other Safety Findings: Cardiovascular SafetyThe VIGOR study showed a higher incidence of adjudicated serious cardiovascular thrombotic eventsin patients treated with VIOXX 50 mg once daily as compared to patients treated with naproxen 500mg twice daily (see Table 2). This finding was largely due to a difference in the incidence of myocardialinfarction between the groups. (See Table 3.) (See PRECAUTIONS, Cardiovascular Effects.)Adjudicated serious cardiovascular events (confirmed by a blinded adjudication committee) included:sudden death, myocardial infarction, unstable angina, ischemic stroke, transient ischemic attack andperipheral venous and arterial thromboses.3

WARNINGSGastrointestinal (GI) Effects—Risk of GI Ulceration, Bleeding, and Perforation[The standard NSAID warning of gastrointestinal effects is retained, with the following addition:]Although the risk of GI toxicity is not completely eliminated with VIOXX® (rofecoxib), the results of theVIOXX GI outcomes research (VIGOR) study demonstrate that in patients treated with VIOXX, therisk of GI toxicity with VIOXX 50 mg once daily is significantly less than with naproxen 500 mg twicedaily. (See CLINICAL STUDIES, Special Studies, VIGOR.)4

PRECAUTIONSCardiovascular EffectsThe information below should be taken into consideration and caution should be exercised whenVIOXX® (rofecoxib) is used in patients with a medical history of ischemic heart disease.In VIGOR, a study in 8076 patients (mean age 58; VIOXX n=4047, naproxen n=4029) with a medianduration of exposure of 9 months, the risk of developing a serious cardiovascular thrombotic eventwas significantly higher in patients treated with VIOXX 50 mg once daily (n=45) as compared topatients treated with naproxen 500 mg twice daily (n=19). In VIGOR, mortality due to cardiovascularthrombotic events (7 vs 6, VIOXX vs naproxen, respectively) was similar between the treatmentgroups. (See CLINICAL STUDIES, Special Studies, VIGOR, Other Safety Findings: CardiovascularSafety.) In a placebo-controlled database derived from 2 studies with a total of 2142 elderly patients(mean age 75; VIOXX n=1067, placebo n=1075) with a median duration of exposure of approximately14 months, the number of patients with serious cardiovascular thrombotic events was 21 vs 35for patients treated with VIOXX 25 mg once daily versus placebo, respectively. In these same 2placebo-controlled studies, mortality due to cardiovascular thrombotic events was 8 vs 3 for VIOXXversus placebo, respectively. The significance of the cardiovascular findings from these 3 studies(VIGOR and 2 placebo-controlled studies) is unknown. Prospective studies specifically designed tocompare the incidence of serious CV events in patients taking VIOXX versus NSAID comparators orplacebo have not been performed.

Because of its lack of platelet effects, VIOXX is not a substitute for aspirin for cardiovascularprophylaxis. Therefore, in patients taking VIOXX, antiplatelet therapies should not be discontinuedand should be considered in patients with an indication for cardiovascular prophylaxis. (SeeCLINICAL STUDIES, Special Studies, Platelets; PRECAUTIONS, Drug Interactions, Aspirin.)Prospective, long-term studies on concomitant administration of VIOXX and aspirin evaluatingcardiovascular outcomes have not been conducted.

ADVERSE REACTIONSRheumatoid ArthritisApproximately 1,100 patients were treated with VIOXX in the Phase III rheumatoid arthritis efficacystudies. These studies included extensions of up to 1 year. The adverse experience profile wasgenerally similar to that reported in the osteoarthritis studies. In studies of at least three months, theincidence of hypertension in RA patients receiving the 25 mg once daily dose of VIOXX was 10.0%and the incidence of hypertension in patients receiving naproxen 500 mg twice daily was 4.7%.

DOSAGE AND ADMINISTRATIONRheumatoid ArthritisThe recommended dose is 25 mg once daily. The maximum recommended daily dose is 25 mg.Management of Acute Pain and Treatment of Primary Dysmenorrhea[The following statement has been added:]Chronic use of VIOXX 50 mg daily is not recommended.* * * * *These and other changes are highlighted in the enclosed Prescribing Information and in the PatientProduct Information, both of which are enclosed.At Merck, we constantly evaluate data concerning our products.

You should see or call your doc. The media and news reporters in general can be deceiving by boiling things down to very simplistic albeit illogical conclusions.
