Abstract:
BACKGROUND:Nevirapine (NVP) is a nonnucleoside reverse transcriptase inhibitor used in HIV patients and recently evaluated as a differentiating and antiproliferative agent in human malignancies. However, while NVP is a safe treatment in immunocompromised patients, NVP-containing regimens have been associated with severe immune-mediated toxicities in non-HIV individuals. METHODS AND RESULTS:We describe the toxicity profile of single-agent NVP in 6 non-HIV cancer patients treated for a median period of 7.3 months (range 1-24), reporting only a reversible grade III increase in glutamyl transpeptidase and glutamic pyruvic transaminase serum values. Interestingly, NVP treatment correlates with either a decrease in CD8+ T cell counts or a parallel increase in CD4/CD8 ratio, antithyroglobulin and antithyroid peroxidase autoantibody titers. CONCLUSIONS:These results, although obtained in a small cohort of patients, suggest that the toxicity profile of single-agent NVP may be worth testing in a phase I/II study in non-HIV cancer patients and that NVP toxicity may depend on its capacity to trigger autoimmune responses in susceptible individuals.
