The study did not present data on any risks associated with new biologic medications, such as Embrel, Humira, and Remicade, which have been available since about 2000, Lindsey and Wilson said. There have been other studies with positive results for one category of these drugs, called TNF-alpha inhibitors, Wilson said. For severe cases, "when we treat them aggressively with a biologic modifier, perhaps we are bringing their risk down to similar to the general population," he said.
