Sales of the Trimeris AIDS drug Fuzeon plunged 34 percent in the first quarter, the biopharmaceutical firm reported Wednesday.
Trimeris (Nasdaq: TRMS) cited sharp declines in sales in the U.S. and Canada as the primary reasons for the falloff.

U.S. and Canada sales plummeted to $17 million, compared with $29.3 million for the same three months in 2007.
