Pfizer said Friday it has stopped a late-stage study of its
drug Lyrica as a potential treatment for HIV-related nerve
pain. In the United States, Lyrica already is approved to
treat nerve pain from diabetes, pain following shingles,
fibromyalgia, and some seizures in adults with epilepsy.
Pfizer has been studying Lyrica's potential use for HIV
neuropathy, a condition involving nerve damage marked by
burning pain that typically begins in the feet. However, an
early analysis of study data found that pain improvements in
treated patients were almost identical to those who received a
placebo. The study did not raise any safety concerns; Pfizer
plans further analysis of the results.
