ClinConnect Summary

A protein in the blood called tumor necrosis factor (TNF-alpha) is abnormally elevated in patients with HIV infection and may cause the body to produce more virus. In vitro studies have demonstrated that thalidomide reduces TNF-alpha levels and inhibits production of HIV. However, more information on the pharmacological and immunological aspects of thalidomide is needed.

Patients are randomized to receive oral thalidomide or matching placebo (3:1) at one of three dose levels daily for 8 weeks. All 12 patients at a dose level must receive treatment for at least 2 weeks before dose escalatio...
