title: [Update on clinical activity of CCI779 (temsirolimus), mTOR inhibitor].
abstract: Temsirolimus (CCI779), an intravenous analog of rapamycin, presents immunosuppressive properties and also antiproliferative activity. Its principal target is the mTOR serine/threonin kinase which controls the initiation of the transcription of many ARNm implicated in carcinogenesis. Breast cancers, glioblastoma and renal cell carcinoma were particularly studied with response rates from 10 to 20 %. In haematology, mantle-cell lymphoma is of particular interest because of constitutional activation of cyclin D1 (response rate of 40 %). As a whole these data define temsirolimus as a promising new drug. Current and further developments are based on its association with chemotherapy in a concomitant or sequential way.
