Brief summary

Phase I trial to study the effectiveness of combining bortezomib with paclitaxel in treating patients who have advanced or metastatic solid tumors. Bortezomib may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Combining bortezomib with paclitaxel may kill more tumor cells.

Detailed description

PRIMARY OBJECTIVES: I. Determine the maximum tolerated dose of bortezomib when given in combination with paclitaxel in patients with locally advanced or metastatic solid tumors. OUTLINE: This is a multicenter, dose-escalation study of bortezomib. Patients receive bortezomib IV on days 2 and 9 and paclitaxel IV over 1 hour on days 1 and 8. For the first course only, patients do not receive paclitaxel on day 1. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of bortezomib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity or greater than 80% 20S proteasome inhibition. Once the MTD is determined, an additional 6-9 patients are accrued and treated at that dose. Patients are followed at 21 days. PROJECTED ACCRUAL: A total of 45 patients will be accrued for this study.

Maximum-tolerated dose (MTD) based on the incidence of DLT21 days

Secondary

MeasureTime frameDescription
Change in NF-kb biomarkers TRAP I and c-IAP-2 in tumor tissue blocksFrom baseline to 6 hours of day 2 (weeks 1 and 2)Descriptive data will be computed and compared using analysis of variance and non-parametric rank equivalents for continuous data and chi-square or Fisher's exact test for discrete data.
Response according to the Response Evaluation Criteria in Solid Tumors (RECIST) CommitteeUp to 21 daysReported descriptively using all eligible patients and evaluable patients separately. Response rates will include 95% confidence limits.
Change in phosphorylation of c-Jun and JNK in tumor tissue blocksFrom baseline to 6 hours of day 2 (weeks 1 and 2)Descriptive data will be computed and compared using analysis of variance and non-parametric rank equivalents for continuous data and chi-square or Fisher's exact test for discrete data.
Change in the level of p27 and Bax proteins in peripheral blood mononuclear cellsFrom baseline to 6 hours of day 1 (week 1) and day 2 (week 2)Descriptive data will be computed and compared using analysis of variance and non-parametric rank equivalents for continuous data and chi-square or Fisher's exact test for discrete data.
Change in plasma levels of TNF, IL-1, IL-6, and C-reactive proteinFrom baseline to 6 hours of day 2 (weeks 1 and 2)Descriptive data will be computed and compared using analysis of variance and non-parametric rank equivalents for continuous data and chi-square or Fisher's exact test for discrete data.
