Background

CPI-1189 is a proapoptotic cytokine tumor necrosis factor (TNF) alpha inhibitor.

AIDS dementia complex is characterized by increased gliosis, apoptosis, and oxidative stress in the CNS, as well as a compromised blood-brain barrier. TNF-alpha has been reported to be elevated in AIDS dementia complex brains and may contribute to AIDS dementia complex.

In vitro: CPI-1189 could potently inhibit p38-MAPK phosphorylation displaying protective action against tumor necrosis factor-alpha (TNFalpha)-induced neurodegeneration. Moreover, in primary astrocytes treated with interleukin 1beta, CPI-1189 inhibited p38-MAPK phosphorylation at low concentrations [1].

In vivo: To model elevated TNF-alpha in AIDS dementia complex, TNF-alpha was infused into rats. Results showed that the co-administration of CPI-1189 prevented TNF-alpha induced apoptosis. Both TNF-alpha and CPI-1189 treatment could suppress glial fibrillary acidic protein staining. TNF-alpha alone did not affect the integrity of the blood-brain barrier significantly, but CPI-1189 treatment increased blood-brain barrier integrity [2].

Clinical trial: Previous clinical study showed that CPI-1189 was well tolerated, with 91% of CPI-1189-treated subjects and 76% of placebo-treated subjects completing the trial. Skin rash was equally found in placebo and drug-treated arms. One subject developed a cataract on CPI-1189. CD4 lymphocyte counts and plasma HIV viral load remained stable in all groups throughout the trial [3].
