Monday, January 24, 2005 Continuing Concerns of the Cardiovascular Risks of the COX-2s
As the European Medicines Agency is set to determine the fate of COX-2s in the European community and the US Food and Drug Administration readies for a rare advisory meeting in mid-February, the journal Circulation has presented a meta-analysis of two clinical trials that provide further evidence that valdecoxib increases cardiovascular risk in CABG patients, including a study that provides a better understanding of the mechanisms in these agents that may accelerate the atherogenic process& Egan KM, et al. Circulation. 2005; 111:334-342.

Friday, January 21, 2005 The Promise and Peril of the Next Generation of COX-2 Inhibitors
CIAOMed continues its series on the impact of the withdrawal of rofecoxib (VioxxR) from the worldwide market. The first installment (CIAOMed.org; November 9, 2004) discussed possible mechanisms of the cardiovascular (CV) risk observed with rofecoxib, and whether they apply to other selective cyclooxygenase-2 (COX-2) inhibitors. The second (CIAOMed.org; December 10, 2004) examined the impact of recent disclosures about COX-2s and CV risk on patient management. This third and final installment focuses on the clues to CV risk profiles of the second-generation COX-2 inhibitors and the role these newer drugs will play if they are approved for marketing in the US& Brune K, Hinz B. Scand J Rheumatol. 2004;33:1-6.

Friday, January 21, 2005 Interpreting TARGET: Who Faces CV Risk?
Rheumatologists interviewed by CIAOMed express caution about the use of lumiracoxib and disagree with some of the interpretations of TARGET findings...Farkouh ME, et al.  Lancet. 2004;364:675-684.

Wednesday, January 19, 2005 Next Generation of Antibody-Based Designer Biologics in Development
Trubion announces first Phase I study of small modular immunopharmaceutical SMIP technology in rheumatoid arthritis…

Tuesday, January 18, 2005 One-Third of US Adults Including Growing Numbers of Arthritis Patients Turn to Complementary and Alternative Medicine
In response to continued use of these products, rheumatologists are urged to become more aware of nonprescription medications and drug-herb interactions...Tindle HA. Altern Ther Health Med. 2005;11:42-49.

Wednesday, December 22, 2004 National Institutes of Health Halts Alzheimer's Prevention Trial Involving Aleve and Celebrex
Federal officials noted that patients taking the OTC formulation of naproxen had a 50% greater rate of cardiovascular (CV) events compared with placebo; those in the COX-2 inhibitor arm of the trial saw no increased CV risk...National Institutes of Health, December 20, 2004.

Tuesday, December 21, 2004 Cancer-Prevention Trial Reveals Elevated Cardiovascular Risk Associated With Celebrex
National Cancer Institute study results, which showed a heightened cardiovascular risk versus placebo among patients taking the COX-2 inhibitor celecoxib at up to 4 times higher than recommended doses, runs counter to recent evidence that the agent may have cardioprotective properties in some arthritis patients... Kimmel SE, et al. Ann Intern Med. 2005;142(3).

Thursday, December 16, 2004 Pfizer's COX-2 Agent to Include Updated Risk Warnings on Label
The FDA announces important new information on risks of CV adverse events in some postsurgical cardiac patients and potentially life-threatening skin reactions associated with use of valdecoxib...US Food and Drug Administration. December 9, 2004.

Tuesday, December 14, 2004 Comparative Trial Analyzes MI Risk Associated With Rofecoxib and Celecoxib
A new study that examines histories of analgesic use in recent MI patients revealed a significant difference in the levels of risk for MI associated with rofecoxib and celecoxib. The study concludes that this is due not to an increase in risk associated with rofecoxib, but rather to a significant decrease in risk in patients using celecoxib&Kimmel SE, et al. Ann Intern Med. 2005;142(3).

Monday, December 13, 2004 Synovial Tissue Interleukin-18 Expression Correlates With Inflammatory Arthritis Disease Activity
New study underscores the important proinflammatory role of IL-18 in the pathophysiology of inflammatory arthritis, and suggests that treatment that inhibits or neutralizes endogenous IL-18 may become an effective tool in controlling synovial tissue inflammation&Rooney T, et al. Ann Rheum Dis. 2004;63:1393-1398.
