--Plaque tissue
While the results of the CEA trial did not demonstrate a reduction in
macrophages in the plaque tissue in carotid arteries of patients treated
with 100mg VIA-2291 compared to those treated with placebo, results of a
post-hoc analysis did show a reduction in necrotic core thickness relative
to plaque thickness. Furthermore, mRNA levels of IL-6, a pro-inflammatory
cytokine, appeared to decrease in plaque tissue from patients treated with
VIA-2291. These findings may indicate anti-inflammatory activity of
VIA-2291 in plaque tissue.
--Safety
The drug was generally well-tolerated in both trials. In the ACS trial, common (>10 percent) adverse events (AEs) with no clear difference between placebo and VIA-2291 treated patients included angina, fatigue, musculoskeletal pain, and headache. Laboratory abnormalities included generally mild, reversible >/= 3x upper limit of normal liver enzymes in the low dose VIA-2291 treated group (10 percent) and placebo (2 percent), not seen in the higher dose drug-treated groups; and asymptomatic >/= 1.5x lipase elevations that were more common in VIA-2291 treated patients. In the CEA study, common AEs (>7 percent) included fever, diarrhea and cystitis that occurred somewhat more commonly in VIA-2291 treated patients. Common laboratory abnormalities included mild reversible elevations of BUN and reversible decreases >1 gm/dL of hemoglobin that were more frequent in VIA- 2291 treated patients.
"We have conducted a preliminary review of the patient safety data for
the VIA-2291 ACS and CEA trials and found that the drug was well-tolerated
at the doses tested and support further development of VIA-2291," said
Sidney Goldstein, M.D., Division of Cardiovascular Medicine, Henry Ford
Hospital, Wayne State University and chairman of the VIA-2291 Data Safety
Monitoring Board (DSMB), wh
