Clinical Trial Summary

Peripheral T-cell lymphomas (PTCLs) are neoplasias from post-thymic T-cells at different stages of differentiation and are a heterogeneous group of malignancies which present with different morphological patterns, phenotypes, and clinical presentations.

These tumours have a striking epidemiological distribution with a lower incidence in Western countries than in Asia. In Korea, PTCLs including T- or natural killer (NK)-cell lymphomas constitute approximately 25 to 35% of all non-Hodgkin's lymphomas. This incidence is quite similar to that of other Eastern Asian countries, including Japan, Hong Kong, and China.

Recent studies suggest that the T-cell phenotype is an independent significant prognostic factor, with PTCLs having one of the lowest overall survival and failure-free survival rates. Based on the investigator's experience, the overall complete remission rate was 61.2% (95% confidence interval [CI]: 48.5-72.8%) and the 5-year probability of failure-free survival was 33.5%. Median survival of all patients was 45 months (range 0-64+ months) and the 5-year probability of survival was 36.2%. Rassidakis et al. reported that expression of pro-apoptotic proteins BAX and BCL-XS, may explain the poor response of many types of PTCL to standard chemotherapy.

To overcome such poor outcome, the optimal therapy for PTCLs remains to be defined. However, because of the rarity of the disease in Western countries, only a few trials have been reported.

Bortezomib (Velcade) is a modified dipeptidyl boronic acid, and a reversible inhibitor of the chymotrypsin-like activity of the 26S proteosome. Bortezomib may induce tumor cell apoptosis or decreased bcl-2 associated drug resistance. Through phase II studies, single agent bortezomib in patients with relapsed indolent and mantle cell lymphomas showed its activity. And also preliminary data indicate that bortezomib can be safely administered in combination with dose adjusted etoposide, prednisolone, vincristine, cyclophosphamide and doxorubicin (EPOCH) chemotherapy. Therefore, it can be possible to improve the poor outcome of patients with PTCLs by a combination of cyclophosphamide, doxorubicin, vincristine, prednisolone (CHOP) with bortezomib as a first-line therapy.

Primary Hypothesis: Based on the clinical trials and experimental data, bortezomib can overcome pro-apoptotic proteins BAX and BCL-XS induced drug resistance.
